Description

  In the present invention, a pressurized steam flow is jetted onto a fiber fabric comprising at least a woven fabric, a knitted fabric, a nonwoven fabric, or a laminated sheet thereof, and various pressures such as washing and decoloring are caused by allowing the pressurized steam to penetrate the fabric. The present invention relates to a steam treatment method for a fiber fabric to be treated.

  Conventionally, proposals for producing a fiber entangled nonwoven fabric using high-pressure steam instead of high-pressure liquid are disclosed in, for example, International Publication No. 95/06769 pamphlet (Patent Document 1) and Japanese Patent Application Laid-Open No. 7-310267 (Patent Document 2). Or it is proposed by the said Unexamined-Japanese-Patent No. 9-256254 (patent document 3).

  For example, according to the method for producing a nonwoven fabric of Patent Document 1, synthetic fibers having a melting point lower than the vapor temperature or the superheated vapor temperature are mixed with all or part of the constituent fibers of the sheet-like fibrous web, A raw material nonwoven fabric is prepared by entanglement of fibers constituting the fiber web by applying a liquid flow in advance, and steam or superheated steam is jetted to the inside of the nonwoven fabric surface to reduce the low of the constituent fibers of the web. A non-woven fabric, which is the final product, is manufactured by welding while melting the melting point fibers. The web entanglement method described in Patent Document 2 attempts to entangle web fibers with each other by using water vapor as a high-pressure fluid. On the other hand, according to the method for producing a nonwoven fabric disclosed in Patent Document 3, water vapor is directly sprayed on the fiber web instead of the conventional high-pressure jet water, and together with the mist-like water generated by the temperature drop at that time Water vapor is applied to the fiber web to entangle the constituent fibers of the web to produce a nonwoven fabric.

  By the way, the technology disclosed in these documents 1 to 3 is a product in which the fibers constituting the sheet-like fiber web whose form is not fixed are entangled by applying steam and the form is stable. A non-woven fabric is to be manufactured.

By the way, conventionally, fabrics made of fiber woven fabrics, knitted fabrics, etc., including the above-mentioned non-woven fabrics whose forms have been stabilized, are various in the process before and after the dyeing or finishing process, or in the dyeing / finishing process. Is being processed. For example, there are various treatments such as steaming heat treatment at the time of dyeing or final finishing, washing after dyeing, removal processing of glue, oil agent, excess resin, etc. adhering to the constituent fibers and yarns of the fabric. In the steaming heat treatment, the fabric is usually introduced into a sealed chamber filled with high-temperature steam and continuously processed, or batch processing is performed by placing it in a high-pressure steam tank for a required time. This steaming heat treatment is indispensable especially for the heat setting of fabrics made of synthetic fibers. The washing is an indispensable process for finishing, and usually, excess dye or dirt adhering to the fabric by pretreatment is washed away through a plurality of washing tanks. Similarly to the cleaning, the removal treatment also removes paste, oil, excess resin, and the like through a plurality of removal liquid tanks.
As described above, in the finishing of the conventional fabric, the treatment is often performed by vapor or liquid.
International Publication No. 95/06769 Pamphlet JP 7-310267 A JP-A-9-256254

  In the conventional finishing process for fabrics, “steaming heat treatment” is a process in which a fabric is placed in or passed through a high-temperature steam atmosphere under various pressures, and the steam is passed through the fabric. In order to completely infiltrate, it takes inevitably a long time and a large amount of steam must be used. As a result, the drainage of the condensed water generated from it must be enlarged.

  In addition, the above-described cleaning treatment and removal treatment are not limited to the long time required for the treatment as in the case of the steaming heat treatment, and the amount of the washing water and the removal liquid is larger than the steaming heat treatment. On the other hand, steam heat treatment is performed for the purpose of, for example, stabilizing the stitches of the knitted fabric, but in this case as well, there is little generation of sewage, but the washing treatment and removal treatment originally wash away excess materials and spots attached to the fibers. In order to remove, sewage is always generated. Further, the cleaning process and the removing process always require a drying process after these processing processes, and a drying facility for that purpose is necessary. This is not only a mere equipment cost, but also leads to a huge increase in the heat energy used compared to the steaming process.

  An object of the present invention is to provide a steam processing method that not only solves many problems of the conventional finishing process but also enables various processes that cannot be predicted by those skilled in the art.

  The present inventors first tried a multi-faceted approach in order to find a new finishing method to replace the conventional finishing process of the fiber fabric as described above. However, in the technical field that is completely different from the conventional finishing process, it is of course impossible to find an alternative technique. Then, when we turned our attention to the technical field related to the same fiber processing again, we were able to find the above-mentioned Patent Documents 1 to 3 in which fibers are entangled to produce a nonwoven fabric.

  The contents of these Patent Documents 1 to 3 are similar to the steam heat treatment in the above finishing treatment in that the heating steam is used even in the production of the nonwoven fabric, and it is expected that this can be used. did. Therefore, as a result of examining the contents of Patent Documents 1 to 3 in detail, it has been concluded that it is difficult to surpass the conventional finishing process unless significant improvements are made as a whole.

The specific reason was as follows.
As long as the contents of Patent Document 1 are analyzed, it is mentioned that high-temperature steam is used, but the steam pressure at the time of injection and the size and shape of the nozzle hole are unique to fiber entanglement by steam. There is no special description regarding various conditions. From this, the production of the nonwoven fabric by high-temperature, for example, superheated steam flow disclosed in the document 1 is not the main purpose of fiber entanglement by the steam flow, and the constituent fibers of the fiber web made of a heat-meltable material with so-called steam heat It can be understood that the main purpose is to melt. Usually, in an entangled nonwoven fabric produced by jetting a high-pressure water stream, a blow mark or an opening mark by the jet fluid remains on the fiber web surface.

  In the nonwoven fabric manufacturing method of Patent Document 1, fiber entanglement is performed by a jet water flow as a pre-process for jetting steam onto a fiber web. Therefore, naturally the above-mentioned striking marks and hole marks remain in the fabric entangled with this jet of water flow, and the high-temperature steam sprayed there does not penetrate the entire surface of the fabric in the thickness direction. , It is thought that it mainly passes through the hitting marks and hole marks. Of course, at this time, the low melting point fibers existing on the other web surface where the hitting marks and the opening marks are not formed are melted at the same time. This can be recognized from FIGS. 4 to 5 of the document 1 because there is a portion where the fibers are fused even in the region where the hitting marks and the opening marks are not formed. As a result, the non-woven fabric shown in the figure has no difference in flexibility from the conventional non-woven fabric by point bonding, and in particular, the surface has hardened portions of many welding materials.

  In addition, Patent Document 2 discloses a structure of one form of a water vapor ejection nozzle, and does not specifically describe the structure, size, usage, or the like of the water ejection nozzle.

  On the other hand, Patent Document 3 describes a specific structure of a water vapor ejection nozzle. However, how water vapor is fed into the water ejection nozzle, and high-pressure water vapor is uniformly distributed from the nozzle under any conditions. There is no specific description of whether or not to erupt continuously. The water vapor used for this ejection is usually industrial water with a slight addition of additives, and it passes through various pipes, so that the water vapor may contain very fine foreign matter. It is easy to close the ejection nozzle hole. Alternatively, a part of the water vapor introduced into the nozzle is condensed and becomes drainage and accumulates in the vicinity of the nozzle hole, so that the nozzle hole is likely to be blocked, and the water vapor is likely to be intermittently ejected without being continuously ejected. Moreover, even if the nozzle structure disclosed in the document 3 can be suitably employed as long as it is a liquid flow injection nozzle, the number of parts is too large and complicated as a vapor injection nozzle.

  Unless the above points are overcome, it is impossible to apply to finishing processing for fabrics. Then, as a result of repeating further examinations and tests to overcome the above problems, the present invention has finally been reached.

That is, the basic configuration of the fiber fabric steam treatment method according to the present invention has a steam inlet connected to a pressurized steam supply pipe at one end and a steam outlet connected to an external steam discharge pipe at the other end. A hollow cylindrical nozzle holder having an opening along the length of the lower surface, and a nozzle member detachable from the lower surface of the nozzle holder and having a plurality of nozzle holes formed facing the opening ; using pressurized steam jetting nozzle comprising comprise, along the width direction of the textile fabric running in one direction and continuously injected pressurized steam from said plurality of nozzle holes on the surface of the textile fabric fibers A steam treatment method for a fabric , wherein the pressurized steam is first introduced from the steam inlet and the pressurized steam is discharged to the outside from the steam outlet, and the temperature in the pressurized steam jet nozzle measuring, the pressure When the temperature of the gas jet inside the nozzle has reached the required temperature, by switching the connection of the steam discharge port drainage passageway through the trap, stopping the discharge of the pressurized steam, the discharge of the pressurized steam after stopping, the textile fabric so as to face the plurality of nozzle holes of the pressurized steam jetting nozzle is continuously running, the pressurized steam jetted from the plurality of nozzle holes between the fibers constituting the textile fabric Vapor suction means is arranged on the opposite side of the pressurized steam jet nozzle with respect to the fiber fabric , and the steam passing through the fiber fabric is sucked out by the steam suction means to the outside. It is in the steam processing method of the textile fabric characterized by including discharging | emitting .

  Such a processing method can be efficiently carried out by a fabric processing apparatus having the following basic configuration. That is, the basic configuration of this processing apparatus relates to an apparatus for processing a fabric by jetting pressurized steam from a plurality of nozzle holes formed in the longitudinal direction of the pressurized steam jet nozzle to the fabric traveling in opposition. A pressurized steam supply source connected to one end of the pressurized steam jet nozzle via a pressurized steam supply pipe; and a steam discharge pipe connected to the other end of the pressurized steam jet nozzle via an open / close valve. A porous fabric transfer body facing the plurality of pressurized steam jet nozzle holes formed in the pressurized steam jet nozzle at a predetermined interval and moving in one direction across the pressurized steam jet nozzle; It is characterized by comprising suction means arranged on the opposite side of the pressurized steam jet nozzle with the transfer body interposed therebetween. As the pressurized steam jet nozzle, it is desirable to employ a pressurized steam jet nozzle in the present invention described later.

  The nozzle holder of the pressurized steam jet nozzle is usually encapsulated with a heat insulating material or the like to prevent the temperature of the pressurized steam passing through the inside from being lowered. Can be heated. Specific methods include heating with a heat medium such as silicon oil and heating with an electric heater such as induction heating. In addition, for example, the entire pressurized steam ejection nozzle is opened on the pressurized steam ejection side. Housed in a box, hot hot air heated in the box is introduced. In this way, if the entire pressurized steam jet nozzle is heated to a temperature equal to or higher than the saturated steam temperature of the steam to be used, for example, by hot air, and maintained, the temperature drop of the internal pressurized steam can be effectively prevented. Thus, not only is it easy to efficiently obtain the amount of steam at the required temperature that acts on the fabric, but it is also easy to obtain a high-quality fabric that has been subjected to the desired treatment.

  On the other hand, normally, the pressurized steam jet nozzle is disposed above the fabric running to apply a pressurized steam jet flow toward the upper surface of the fabric, but the pressurized steam jet nozzle is disposed below the fabric running. Thus, a jet stream of pressurized steam can be applied upward from the lower surface of the fabric. Thus, when the jet stream of pressurized steam is jetted upward from below the fabric, the condensed water of the steam is less likely to accumulate in the nozzle holes arranged on the upper surface side of the nozzle holder, and the nozzle holes are clogged. Does not occur, and stable vapor ejection is possible, which is preferable.

  Even if the pressurized steam is applied from one surface of the fabric with a set of the pressurized steam jet nozzles and the suction means for the steam disposed opposite to the nozzles, the initial object of the present invention is achieved. Alternatively, two or more sets of the pressurized steam ejection nozzle and the steam suction means may be prepared, and these may be alternately arranged on both the front and back surfaces of the fabric so that the pressurized steam is ejected from both the front and back surfaces of the fabric. In this case, since a jetted flow of pressurized steam is applied from the front and back of the fabric, it acts evenly not only on the surface layer of the fabric but also on the internal constituent fibers, and is desired uniformly throughout the thickness direction of the fabric. Can be processed. Moreover, a vapor | steam reflecting plate can also be distribute | arranged between the said fabric which drive | works in one direction, and the said suction means.

  When the pressurized steam is ejected from the pressurized steam ejection nozzle toward the surface of the fabric under suitable conditions, the pressurized steam penetrates the fabric, and the fibers and yarns constituting the fabric while passing through the fabric. The pressurized steam is subjected to various treatments as will be described later. However, when comparing the processing results of the fibers and yarns on the pressurized steam ejection side and the through side of the fabric, the processing of the constituent fibers and yarns on the steam ejection side proceeds more than the processing of the constituent fibers and yarns on the penetration side. I found out. Therefore, when the pressurized steam is jetted in both directions with respect to the front and back surfaces of the fabric as described above, the progress of the processing is naturally equalized on the front and back surfaces of the fabric. Also, by arranging the above-described vapor reflector, the vapor that has penetrated the fabric is reflected by the vapor reflector on the surface on the penetration side of the fabric, and the treatment of the constituent fibers or yarns on the vapor reflector is promoted. For example, even when pressurized steam is ejected from one direction to the fabric, processing of fibers and yarns constituting the fabric on the opposite side proceeds, so that both the front and back surfaces are easily treated in a uniform and stable manner.

The fabric transfer body may be a porous endless belt that rotates and drives in one direction, or a porous rotary drum that rotates and drives in one direction.
In the former case, a suction means having a slit-like suction opening is arranged inside the endless belt and facing the nozzle hole of the pressurized steam jet nozzle, but also in the latter case, Desirably, a suction means having a slit-like suction opening is disposed at a portion facing the nozzle hole of the pressurized steam jet nozzle inside the rotating drum. All of these suction means are fixed so that the slit-like suction opening is along the nozzle hole of the pressurized steam jet nozzle. It is desirable that the endless belt or the rotating drum rotate as close to the slit-like suction opening surface as possible.

  When a porous rotating drum is employed as the fabric transfer body, the overall size of the apparatus can be reduced. The structure and arrangement of the rotating drum and suction means can be substantially the same as the structure and arrangement of the rotating drum and suction means employed in the circular net paper machine. Further, as the porous endless belt and the rotating drum, for example, a metal net or punching metal can be used. At this time, the mesh degree of the fabric transfer body is desirably 20 (pieces / 2.54 cm) or more. If the mesh degree of the fabric transfer body is less than 20 (pieces / 2.54 cm), the suction efficiency by the suction means is increased. It decreases and moisture tends to remain in the fabric. Further, it is particularly preferable that the mesh degree exceeds 40 (pieces / 2.54 cm) because the suction efficiency is increased and the action of the vapor is uniformly applied to the entire fabric. The vapor reflector preferably has a hole with a diameter of 1 to 10 mm and a porosity of about 10 to 50%.

  Usually, the pressurized steam jet nozzle is fixed at a predetermined position and is in an immobile state, and the fabric transfer body is also only moved in one direction so as to transfer the fabric in one direction. In the present invention, the pressurized steam jet nozzle is reciprocated in a short stroke in the transverse direction of the cloth transfer path, or the pressurized steam jet nozzle is fixed, and the cloth transfer body is moved to the cloth transfer path. It is preferable to reciprocate with the same short stroke in the transverse direction. Both the pressurized steam jet nozzle and the fabric transfer body may be reciprocated. As described above, when either or both of the pressurized steam ejection nozzle and the fabric transfer body are reciprocated, the pressurized steam is uniformly ejected in the width direction of the fabric, and the nozzle is formed on the surface of the fabric to be manufactured. A moire-like pattern due to the steam ejected from the holes is not formed, and a fabric having a uniform surface form is obtained. The stroke width of this reciprocation may be slightly longer than the pitch between nozzles, specifically about ± 5 mm, and the reciprocating speed is 30 to 300 times / min.

  By the way, although the gap between the nozzle hole of the pressurized steam jet nozzle and the fabric varies depending on the purpose of processing the fabric, it is often preferable that the gap is as small as possible. However, when the nozzle hole of the pressurized steam jet nozzle and the fabric are brought into sliding contact with each other, damage due to wear of both is severe, and it becomes difficult to obtain the required durability. Therefore, it is desirable to have means for adjusting the gap between the nozzle hole of the pressurized steam jet nozzle and the fabric. By this gap adjusting means, the gap between the nozzle hole of the pressurized steam jet nozzle and the fabric can be optimally adjusted, and at the same time, the durability of the apparatus is ensured. Further, the fabric transfer may be performed while holding the fabric. In this case, the fabric may be provided with a fabric support transport body that supports the fabric from below and a fabric press transport body that presses the fabric from above. Also in this case, it is desirable to provide a second gap adjusting means for adjusting the gap between the cloth carrying and transporting bodies so that the holding force can be adjusted in accordance with the constituent fiber material and the web thickness of the cloth. .

  Further, in this processing apparatus, a steam storage part is arranged in the pipe line of the pressurized steam supply pipe, the steam is temporarily stored in the steam storage part, and the dust etc. in the steam stored there is condensed liquid. At the same time, it is preferable that the gas can be discharged to the outside through a trap, for example. Further, a heating means is disposed in a pressurized steam supply pipe line between the steam storage section and one end of the pressurized steam jet nozzle, and between the steam storage section and the steam jet nozzle, It is preferable to generate superheated steam by additionally superheating the steam of the pressurized steam passing through the heated steam supply pipe, so that extremely high temperature steam can be ejected to the fabric under a desired high pressure. At this time, when the vapor pressure introduced into the vapor ejection nozzle is 0.1 to 2 MPa, it is often preferable because the vapor can surely penetrate the front and back of the fabric.

  The pressurized steam ejected from the steam ejection nozzle is ejected to the outside from the nozzle hole, and at the same time, the temperature is rapidly lowered by adiabatic expansion. Due to this decrease in temperature, the vapor is likely to condense into a mist-like liquid, which blows up to the periphery and is no longer a high-pressure fluid, so that it is difficult to reach the inside of the fabric. Superheated steam is steam that has been heated to a temperature equal to or higher than the saturation temperature under saturated steam pressure, and condensate liquefaction hardly occurs between the saturation temperature and the superheated temperature. Therefore, the superheated steam ejected from the steam ejection nozzle does not condense even if it hits the fabric, penetrates and penetrates to the inside, and advances the processing while heating the surrounding fibers.

  Further, in the processing apparatus, a trap pipe branching from a pipe of a steam discharge pipe between the opening / closing valve and the other end of the pressurized steam jet nozzle can be arranged. Prior to the start of operation of the apparatus as described above, the open / close valve provided in the steam discharge pipe connected to the steam discharge port of the steam discharge nozzle is opened, and pressurized steam is introduced from one end of the steam discharge nozzle, and the other end When the steam is discharged from the steam outlet and the internal temperature of the steam ejection nozzle rises to a predetermined temperature, the open / close valve is closed.

  As described above, if a trap pipe branched from the pipe of the steam discharge pipe is provided, the minute foreign matter contained in the condensate or steam generated in the steam jet nozzle after the opening / closing valve is closed. Flows along with the condensate to the trap line via the vapor discharge pipe and is discharged to the outside in a timely manner, and the nozzle hole is not clogged with the condensate and fine foreign matter even during operation of the device. Steam can be stably ejected from all nozzle holes.

  As the steam jet nozzle applied to the processing apparatus for carrying out the same method as the processing method of the present invention, a pressurized steam jet nozzle having the following configuration can be employed. In the present invention, the pressurized steam jet nozzles are generally arranged in a single stage without causing any particular trouble, but the steam jet nozzles can be arranged in multiple stages in the running direction of the fabric. In this case, as described above, if the pressurized steam jet nozzle and the suction means are alternately arranged on the front and back of the fabric, uniform fabric processing can be performed. Furthermore, it is desirable to displace the nozzle holes of the pressurized steam nozzle in the width direction of the fabric for each step.

  The basic structure of the pressurized steam jet nozzle has a steam inlet connected to a pressurized steam supply pipe at one end, a steam outlet connected to an external steam discharge pipe at the other end, and in the length direction of the lower surface. A hollow cylindrical nozzle holder having an opening extending along the nozzle holder, and a nozzle member that is detachably disposed on the lower surface of the nozzle holder and has a plurality of nozzle holes formed facing the opening. desirable.

  The most notable point here is that the nozzle holder has a steam inlet at one end and a steam outlet at the other end. Steam cannot always be ejected from the steam ejection nozzle. For example, the supply of steam is also stopped during periodic inspections or when the machine is stopped. When the vapor ejection is stopped in this way, the temperature in the nozzle naturally decreases rapidly. In order to restart the ejection of steam and start the treatment of the fabric, it is necessary to raise the temperature of the interior of the steam ejection nozzle to a predetermined temperature. When the temperature is raised, when the configuration other than the steam inlet is sealed like the conventional ejection nozzle, the amount of steam introduced into the nozzle holder is limited to the amount ejected from the nozzle hole, and the amount of heat exchange is small. It takes a long time to raise the temperature of the nozzle itself.

  Therefore, in the present invention, as described above, a steam exhaust port is provided at the other end of the nozzle holder, and an open / close valve or the like is attached to the steam exhaust pipe connected to the steam exhaust port, as described later. The outlet can be opened and closed. Now, before starting the fabric manufacturing apparatus, steam is introduced into the nozzle holder. At this time, the steam outlet is opened, and the steam introduced from the steam inlet is continuously discharged to the outside through the steam outlet. The temperature of the nozzle holder is measured, and when the temperature reaches a predetermined high temperature, the steam outlet is closed. Simultaneously with this closing, the vapor pressure at the vapor inlet is measured, and when the vapor pressure reaches a predetermined pressure, the fabric production apparatus is started. The time to start at this time is significantly shortened compared to the case where there is no steam outlet as in the conventional case because the temperature of the nozzle holder is quickly raised by new high-temperature steam passing through the nozzle holder.

  Specific examples of the shape of the hollow cylindrical nozzle holder include a cylindrical nozzle holder and a rectangular nozzle holder, and the cylindrical nozzle holder is particularly preferable from the viewpoint of uniform flow of pressurized steam and production. Used. Also, during actual work, a mesh cylindrical filter, such as a cylindrical filter in the case of a cylindrical nozzle holder, or a rectangular filter in the case of a rectangular nozzle holder, is used inside the nozzle holder. Although it is desirable to arrange | position on the same axis line, it is not necessarily limited to these.

  In the present invention, when a cylindrical nozzle holder is used as described above, it is desirable to dispose a mesh cylindrical filter on the same axis inside the nozzle holder. In this case, the steam introduced from the steam inlet provided at one end of the nozzle holder is introduced into the cylindrical filter, passes through the filter, reaches the nozzle hole formed in the nozzle plate, and the nozzle hole Erupts outside. At this time, the pressure distribution in the longitudinal direction on the inner wall surface of the nozzle holder is made uniform by the cylindrical filter, and fine foreign substances contained during the introduction of the steam are removed from the steam by the cylindrical filter. Without blocking the nozzle hole of the nozzle member formed along the direction, high-pressure steam is stably ejected from the nozzle hole with an equal ejection pressure. The mesh filter has a pore diameter of about 1 to 50 μm for the purpose of removing fine foreign substances contained during the introduction of steam.

  The nozzle holder has a drain outlet at its lower part. Furthermore, it is preferable that the nozzle holder is inclined alone or together with the nozzle member. This is because the drain accumulates in the nozzle holder during operation, so that the drain can be easily discharged to the outside. For this reason, a drain discharge port is formed at the lower end of the nozzle holder in the tilt direction and can be opened and closed by an open / close valve, for example, and the drain is collected inside the nozzle holder by opening the valve at an arbitrary time zone. Is discharged to the outside. At this time, since the nozzle holder is inclined, an extra device such as suction is not required if it is allowed to flow naturally. The nozzle holder may be tilted independently or may be tilted together with the nozzle member.

  Furthermore, since the drain does not cause clogging such as nozzle holes, a step is provided between the bottom surface of the nozzle holder and the arrangement plane of the nozzle member, or a drain channel (groove) is formed on the bottom surface of the nozzle holder, Furthermore, a drain channel that communicates with a part of the bottom surface of the nozzle holder may be provided independently of the nozzle holder. In the case of providing the drain flow path independently, only the flow path may be tilted without tilting the nozzle holder as described above. The gradient is desirably 1/100 at the maximum (100 mm length and 1 mm height gradient), and more preferably 1/500 or more. If it exceeds 1/100, uniform steam treatment cannot be performed, and if it is less than 1/500, the drain does not flow easily unless surface treatment is applied to the inner wall surface of the nozzle holder.

  On the other hand, the opening formed in the lower surface of the nozzle holder may be a slit-like opening formed continuously in the length direction of the nozzle holder, or formed in a staggered shape in the length direction of the nozzle holder. It may be a large number of small holes. The pressure of the steam reaching the nozzle holes formed in the nozzle member through these openings is equalized, and the steam can be uniformly injected in the longitudinal direction of the nozzle. Naturally, the drain flow path is formed at a portion off the opening of the nozzle holder.

  The nozzle member can be composed of a nozzle plate having a number of nozzle holes and a plate support member that supports the nozzle plate. The nozzle hole preferably has a cylindrical hole. The shape of the cylindrical hole may be a simple cylindrical shape, but may further have an inverted trapezoidal portion continuous to the upper end of the cylindrical hole of the nozzle hole, or the nozzle hole may extend from the lower end periphery of the cylindrical hole. You may make it have a ring piece extended concentrically toward the inside of a mustache, Preferably on a concentric circle. Furthermore, a continuous groove portion having an inverted trapezoidal cross section that is continuous in the longitudinal direction of the nozzle plate may be provided at the upper end of the cylindrical hole of the nozzle hole, or an inverted truncated conical hole is provided at the upper end of each cylindrical cylindrical hole. You may make it have.

  The nozzle holes formed in the nozzle plate may be formed in a single row in the longitudinal direction of the nozzle plate, but may be formed in a plurality of rows in the width direction of the nozzle plate, for example. In this case, it is preferable to arrange a plurality of rows of nozzle holes in a zigzag pattern because the jetted steam acts uniformly in the width direction of the fabric.

  The ratio between the height and the inner diameter of the cylindrical hole, preferably a cylindrical cylindrical hole, is preferably 1 to 2. If the value is smaller than 1, the steam flow is difficult to be a columnar flow, and if it is larger than 2, high-precision machining is difficult due to the small nozzle hole diameter and the thickness of the nozzle plate. In addition, although the accuracy in processing is required, if possible, the nozzle hole is configured to have a ring piece that extends concentrically from the lower peripheral edge of the cylindrical tube hole toward the inside of the mouthpiece as described above. By doing so, the steam flow ejected from the nozzle holes is converged at a certain point, and for example, the penetration force to the fabric is increased, and the front and back of the web can be easily penetrated. The focusing point is determined by the diameter of the nozzle hole and the vapor pressure.

  It is preferable that the thickness of the nozzle plate is 0.5 to 1 mm, the inner diameter of the vapor outlet of the nozzle hole is 0.05 to 1 mm, and the pitch between the nozzles is 0.5 to 3 mm. If the plate thickness of the nozzle plate is smaller than 0.5 mm, it is difficult to obtain sufficient strength to withstand the vapor pressure, and if it exceeds 1 mm, it is difficult to process a fine nozzle hole with high accuracy. Electric discharge machining or laser machining can be employed for forming the nozzle holes. Also, depending on the purpose of processing the fabric, if the inner diameter of the steam outlet of the nozzle hole is smaller than 0.05 mm, the processing is difficult, and clogging is likely to occur. Is difficult to obtain. When the pitch between the nozzles is 0.5 to 3 mm, there is no interference with the steam flow ejected from the adjacent nozzle holes, and at the same time, the pressurized steam stably penetrates the fiber fabric, and the constituent fiber or configuration of the fabric Pressurized steam reaches the yarn sufficiently, and the desired treatment is performed evenly and uniformly. In addition, the pitch between nozzles says the distance between the center points of each nozzle hole.

  Further, in the present invention, the nozzle member includes a ship-shaped recessed groove portion communicating with the lower end opening of the nozzle holder, a rectangular cross-sectional groove portion formed along the bottom of the recessed groove portion, and the rectangular cross-sectional groove portion. It comprises a single member comprising a plurality of inverted frustoconical holes formed at a predetermined pitch along the length direction and a cylindrical tube hole formed continuously at the lower end of each inverted frustoconical hole. You can also By configuring the nozzle member as a single member in this way, not only the number of parts can be greatly reduced, but also the spray opening end of the nozzle hole can be brought close to the spray surface of the fabric. Pressure loss due to adiabatic expansion of pressurized steam is reduced, and more penetration force in the web is obtained. Furthermore, if the lower end surface shape in the width direction of the nozzle member is a curved surface shape protruding downward, the introduction of the fabric is facilitated. Even in this invention, it is preferable that the value of the ratio between the height and the inner diameter of the cylindrical hole is 1-2, and the inner diameter of the steam outlet of the nozzle hole is 0.05-1 mm, and the pitch between the nozzles Is preferably 0.5 to 3 mm. The pitch between the nozzles in this case also refers to the distance between the center points of the nozzle holes, as described above. Also in this case, it is preferable to form the nozzle holes in a plurality of rows in the longitudinal direction of the nozzle member.

  By the way, the fiber fabric referred to in the present invention may include at least a woven fabric, a knitted fabric, a non-woven fabric, or a laminate sheet of these, and may have a structure through which steam penetrates. Things are also fiber fabrics. The fibers constituting the fabric of the present invention include organic fibers (natural fibers such as wool, hemp and silk, synthetic fibers such as polyester fibers, acrylic fibers and polyamide fibers, semi-synthetic fibers such as acetate fibers, and rayon. Recycled fibers represented), inorganic fibers (glass fibers, mineral fibers, metal fibers, etc.) alone, or organic fibers or inorganic fibers, or organic fibers and inorganic fibers in combination.

  According to the method for steam treatment of a cloth according to the present invention, for example, it is possible to perform a washing process, a decoloring process, a liquid removing process after a liquid process, a fabric texture improving process, and various chemical treatments for the cloth. Become. Of these examples, steaming heat treatment may be performed for fabric texture improvement treatment or normal heat setting, etc., but fluid treatment is generally adopted for other treatments, and the fabric is also subjected to the steaming heat treatment. It is placed in an atmosphere of high temperature steam or simply passed through the same atmosphere.

  As described above, the fabric steam treatment method according to the present invention tries to perform various treatments as described above by ejecting pressurized steam from the pressurized steam ejection nozzle toward the fabric and penetrating the fabric. Is. Therefore, the heated steam treatment method ejected from the pressurized steam ejection nozzle of the present invention is a treatment method essentially different from the conventional liquid treatment method, and also coincides with the conventional steaming heat treatment in that steam is used. However, not only the configuration but also the functions and effects are completely different.

  The washing treatment of the fabric according to the present invention can remove excessive dyes and the like in the same manner as with conventional washing liquid or water, but further, such as glue, oil agent, various resins, etc. adhering to the fabric or its constituent fibers. It is possible to reliably remove deposits. This is because when the pressurized steam penetrates the fabric, it is not affected by the material of the adhered material such as glue, oil, and various resins that adhere to the fibers and yarns constituting the fabric. By instantaneously entraining the fabric with steam. For example, a woven fabric or knitted fabric made of metal fibers is used as a web transfer means in the production process of a spunbond nonwoven fabric or a melt blown nonwoven fabric, but is in a fibrous state in a molten state on the fabric made of the woven fabric or knitted fabric. When the formed polymer cools, it can also be used to wash the deposits stuck to the fabric. In this invention, since it is a vapor | steam (gas) process instead of a liquid process, various processes can be performed, without making a water | moisture content adhere to the fiber and yarn which comprise a fabric. Therefore, as described later, it is not necessary to pass the washed fabric again through a heat drying step or a solvent removal step. This leads to a significant reduction in equipment costs and energy costs.

  In addition, the above decolorization treatment is performed by, for example, easily decolorizing a part of the dyeing in the case of a raw material before it becomes a product easily by the steam treatment method of the present invention instead of decolorization using a conventional decolorizing agent. If the cloth transfer speed and the vibration in the width direction between the cloth and the transfer means are appropriately combined and controlled, a moire pattern can be created and the original fabric can be damaged. There is nothing.

  Further, after the liquid treatment, for example, the liquid removal (drying) treatment for the washed fabric is impregnated or adhered with a large amount of the treatment liquid in all steps as in the washing treatment. That is, since the liquid component can be efficiently removed from the fabric as in the normal drying step, the method of the present invention may be applied in place of all the conventional drying steps. In this case, a large drying chamber, a large number of heating lamps, heating drums and heating rolls, electrical energy and fluid energy supply equipment connected to these heating lamps, heating drums or heating rolls, exhaust equipment, etc. are unnecessary and used. The amount of energy is also greatly reduced compared to the conventional case. In addition, the fabric texture-improving treatment also has fewer steps compared to, for example, conventional washing and knitting methods for woolen fabrics and knitted fabrics, and the surface that is clogged in a short time has a soft feeling. A rich wool fabric can be processed continuously and efficiently. Further, in the present invention, if the medicine injection path is further joined to the steam introduction path of the steam nozzle holder and the medicine is ejected to the fabric together with the pressurized steam, the medicine treatment can be performed simultaneously with other processes.

  These various treatment methods can be carried out by suitably combining treatment conditions such as the transfer speed of the fabric, the temperature and vapor pressure of the pressurized steam, and the gap between the fabric and the ejection opening end of the nozzle. Become. Furthermore, these values are determined by determining the type of fabric (woven fabric, knitted fabric, non-woven fabric, etc.) and structure (woven or knitted structure, woven or knitted density, non-woven fabric fiber density), fabric constituent fiber and yarn material, and fabric. Since it is made based on fabric conditions such as the thickness of the film, it cannot be determined uniformly.

Hereinafter, a preferred embodiment of a method for treating a fiber fabric using pressurized steam according to the present invention will be specifically described with reference to the drawings.
FIG.1 and FIG.2 has shown the outline | summary of the fabric treatment process which is 1st Embodiment of the processing method of the fiber fabric based on this invention. Specifically, an endless belt 30 is disposed below the pressurized steam jet nozzle 10 described later at a predetermined interval. The endless belt 30 rotates in one direction so as to cross the pressurized steam jet nozzle 10. Therefore, both end reversing portions of the endless belt 30 are driven and supported by a driving roll 31 and a driven roll 32 that are driven by a driving motor (not shown), and are supported by a tension roll 33 on the lower side to be suitable for the endless belt 30. Giving proper tension. The endless belt 30 is made of, for example, a mesh-like woven fabric or a thin metal punching plate material woven coarsely by using a thick filament made of synthetic resin.

  The mesh degree is arbitrarily set. Further, the interval between the pressurized steam jet nozzle 10 and the fabric carried by the endless belt 30 is also a cleaning process, or a paste, an oil agent that adheres to fibers and yarns constituting the fabric, It depends on the type of treatment, such as whether it is a resin removal treatment, and the type of fabric, whether it is a woven fabric, a knitted fabric or a non-woven fabric, and further, the material of the constituent material, woven / knitted density, fiber density, yarn thickness It differs depending on the size, fineness, fabric thickness, etc., and is generally difficult to determine. The steam pressure introduced into the pressurized steam jet nozzle 10 is preferably 0.1 to 2 MPa. If the steam jetted from the steam jet nozzle is superheated steam, the steam is jetted from the pressurized steam jet nozzle 10. Even if the superheated steam causes a temperature drop due to adiabatic expansion, it does not become a mist-like steam and does not scatter.

  A suction means is disposed below the endless belt 30 corresponding to the installation site of the pressurized steam jet nozzle 10. In the present embodiment, the suction means includes a suction box 40, a vacuum pump 42 connected to the suction box 40 via a separator tank 41 via a pipe, and a mist separator 43 connected to the discharge side of the vacuum pump 42. Consists of Here, the separator tank 41 is a gas-liquid separation tank for separating the vapor sucked by the suction box 40 into a gas-liquid, and the mist separator 43 is a foreign substance or harmful gas in the vapor discharged from the vacuum pump 42. Alternatively, the liquid or the like is removed from the vapor to release clean vapor (gas) to the outside, and also has a function as a silencer that reduces noise generated from the vacuum pump.

  The pressurized steam jet nozzle 10 has a nozzle structure as shown in FIGS. 3 to 18 to be described later, and high-pressure steam supplied from the pressurized steam supply source S is introduced into the steam introduction side end thereof. It is introduced through the side main line (c1). In the steam introduction side main pipe (c1), the steam sent from the steam supply source S is once guided to the steam storage section 51, and the drain contained in the steam is stored at the bottom thereof, and this is connected to the second trap pipe. It collects in a collection tank (not shown) via 57. The steam introduced into the steam reservoir 51 is heated by the heater 54 through the pressure control valve 52 and the precision filter 53 to become superheated steam, and is sent to the pressurized steam jet nozzle 10.

  In the present embodiment, a temperature detector TI and a pressure detector PI are arranged between the heater 54 and the steam introduction side end of the pressurized steam jet nozzle 10. The steam introduction side pipe line (c1) has a steam replenishment line (c2) branched from the installation site of the heater 54, and this steam replenishment line (c2) is connected to the pressurized steam supply source S. ing. A first open / close valve 55 that operates in response to a temperature detection signal from the heater 54 is interposed in the middle of the steam replenishment line (c2), and the steam temperature detected by the temperature detector TI is When the temperature falls below the lower limit, the on-off valve 55 is opened to supply new steam to the steam introduction side main pipe (c1) to raise the superheated steam temperature to a predetermined temperature range. When the steam temperature exceeds the upper limit temperature, the opening / closing valve 55 is closed to shut off the supplementary steam.

  With the system as described above, the temperature of the target steam can be controlled within a predetermined temperature range. The pressure detector PI is connected to a pressure control valve 52 disposed on the upstream side of the precision filter 53, and adjusts the vapor pressure in the vapor introduction side main pipe (c1) to be kept constant. The precision filter 53 preferably has a pore diameter of 0.5 to 10 μm.

  On the other hand, a second temperature detector TI is disposed at the end of the steam discharge nozzle 10 on the steam discharge side, and the end of the steam discharge side is connected to the steam discharge pipe (c3). A second open / close valve 56 connected to the second temperature detector TI and closed when the steam temperature detected by the temperature detector TI reaches a set temperature is connected to the steam discharge pipe (c3). It is intervened. Further, even when the second trap pipe 57 is branched from the downstream side of the second on-off valve 56 and the second on-off valve 56 is closed and the steam discharge pipe (c3) is closed, The drain generated inside the nozzle holder 11 (FIG. 2) of the pressurized steam jet nozzle 10 is always discharged to a collection tank (not shown).

  Further, in the present embodiment, in FIG. 2, a steam condensate discharge port is formed on the bottom surface of the nozzle holder 11 at the pressurized steam introduction side end, and the discharge port is connected to the drain line (c4). The third open / close valve 62 is connected. At this time, the pressurized steam jet nozzle 10 lifts the end of the steam discharge pipe (c3) slightly with the pressurized steam introduction side end as a base end, Keep it tilted. The pressurized steam introduced into the nozzle holder 11 inevitably condenses and liquefies during operation of the pressurized steam ejection nozzle 10. As described above, a first nozzle plate support member, which will be described later, is fixedly attached to the bottom side opening of the nozzle holder 11. For this reason, a step is formed between the bottom surface of the nozzle holder 11 and the first nozzle plate support member so that the top surface of the support member becomes higher. Normally, a condensate liquid generated in the nozzle holder 11 ( Water) does not reach the nozzle plate, but when the amount of condensate increases, it does not necessarily flow into the nozzle plate beyond the step. As a result, clogging occurs in the nozzle holes formed in the nozzle plate, and the pressurized steam is not smoothly ejected.

  As described above, if a steam condensate discharge port is formed on the bottom surface of the pressurized steam introduction side end of the nozzle holder 11 and is connected to the drain line (c4) via the third on-off valve 62, If necessary, the third open / close valve 62 can be opened to discharge the condensate accumulated on the bottom surface of the nozzle holder 11 to the outside. At this time, if the pressurized steam introduction side end of the nozzle holder 11 is set to be slightly lower than the end of the steam discharge pipe (c3) as described above, the bottom surface of the nozzle holder 11 Since the condensate accumulated in the gas is automatically collected at the condensate discharge port at the end of the pressurized steam introduction side, the discharge becomes easy. In order to collect the condensate on the bottom surface side of the nozzle holder 11 and smoothly flow to the end of the pressurized steam introduction side, a concave groove extending in the longitudinal direction is formed on the bottom surface of the nozzle holder 11. Is preferred.

  An exhaust port of the top plate portion of the separator tank 41 is connected to a suction pipe (c4) connecting the vacuum pump 42 via an opening / closing valve 47, and the bottom of the separator tank 41 is connected to a water pump via a fluid pump 48. It is connected to a supply source W. Further, a water level detector 49 is arranged between the upper limit water level portion and the lower limit water level portion of the separator tank 41, and when the water level of the separator tank 41 exceeds the upper limit or falls below the lower limit, a signal is sent to the not shown. The operation of the fluid pump 48 is stopped by a command from the control device.

  Further, in the present embodiment, the opening / closing lid 60 is installed so as to enclose the installation part of the pressurized steam jet nozzle 10. A suction pump 61 is connected to the top plate portion of the open / close lid 60. The suction pump 61 constantly sucks and discharges mist-like water vapor generated at the installation portion of the pressurized steam jet nozzle 10 to the outside. ing. Although not shown in the present embodiment, naturally, the pressurized steam jet nozzle 10 and its steam introduction pipe and steam discharge pipe are insulated by a glass fiber mat with an aluminum foil except for the steam jet nozzle hole. It is covered with a material.

  According to the fabric processing apparatus of the present embodiment configured as described above, prior to operation, first, the second on-off valve 56 of the steam discharge conduit (c3) of the pressurized steam jet nozzle 10 is opened to introduce steam. When high-pressure superheated steam is introduced from the side main pipe (c1), fresh superheated steam flows through the inside of the nozzle holder 11 of the pressurized steam jet nozzle 10 from its introduction side opening to the discharge side opening. The temperature is quickly raised to the required superheat temperature. At this time, the temperature is detected by the temperature detector TI installed at the vapor discharge side end of the nozzle holder 11, and when the detected temperature reaches a required temperature, the second opening / closing valve 56 is closed. Simultaneously with closing the opening / closing valve 56, the endless belt 30 is driven to start its rotation.

  On the surface of the fabric T transferred on the belt by the rotation of the endless belt 30, columnar or convergent flow superheated steam having uniform pressure and temperature ejected from each nozzle hole of the pressurized steam ejection nozzle 10. The strong superheated steam flow penetrates into the fabric, and the fiber fabric by steam is continuously processed through the web while simultaneously setting the heat while entangling the surrounding fibers. At this time, the second open / close valve 56 installed in the steam discharge pipe (c3) is in a closed state, and drainage is generated inside the nozzle holder 11 of the pressurized steam jet nozzle 10. The fuel is always collected in a recovery tank installed outside the system via a second trap pipe 57 branched from the upstream side of the second opening / closing valve 56.

  As a result, the nozzle hole 16a is not clogged, and the superheated steam ejected from the nozzle hole 16a is ejected stably and continuously without being intermittently ejected. In this way, stable superheated steam is continuously jetted onto the surface of the traveling fiber web, so that the entire web is evenly entangled and an extremely high-quality fabric with the required strength is processed. Is done.

  FIGS. 3-6 has shown the 1st structural example of the typical Example of the said pressurized steam injection nozzle which is also an important structural member of this invention. The pressurized steam jet nozzle 10 according to the first structure example includes a nozzle holder 11, first and second flanges 12 and 13 fixed to both ends of the nozzle holder 11 by welding, and the nozzle holder 11. A cylindrical mesh filter 14 that is inserted and supported at both ends by first and second flanges 12 and 13 and a number of nozzle holes that are fixed by welding or bolts along the lower surface of the nozzle holder 11. And a nozzle member 15. The nozzle member 15 according to the illustrated example includes a first and second nozzle plate support members 15a and 15b, and a nozzle plate 16 fastened by a fixing bolt between the first and second nozzle plate support members 15a and 15b. And.

  The first flange 12 fixed to the steam introduction side end of the nozzle holder 11 has a through hole 12c formed of a large diameter portion 12a and a small diameter portion 12b along the center line, and is not shown. It is connected via a plug 17 to a pressurized steam supply pipe (not shown) connected to a supply source. The second flange 13 fixed to the steam discharge side end of the nozzle holder 11 is also formed with a through hole 13c having a large diameter portion 13a and a small diameter portion 13b along the center line, and an exhaust gas not shown in the figure. It is connected to a steam exhaust pipe (not shown) connected to the fan. At both ends of the mesh filter 14, ring-shaped fixing members 18 and 19 that are airtightly fixed to the large-diameter portions 12 a and 13 a of the first and second flanges 12 and 13 are fixed.

  On the lower surface of the nozzle holder 11, a cut surface 11a is formed by being cut out in a plane until the inner space is reached, leaving both ends thereof. As a result, a slit-like opening 11 b is formed in the longitudinal direction at the center of the lower surface of the nozzle holder 11. As shown in FIGS. 3 and 4, the nozzle member 15 includes a prismatic first nozzle plate support member 15a and a plate-like second nozzle plate support member 15b having the same length and width as the first support member 15a. It consists of. A concave portion 15a 'is formed in the longitudinal direction at the center of the lower surface of the first nozzle plate support member 15a except for both ends in the longitudinal direction. Further, a large number of through-holes 15a ″ communicating with the recessed portions 15a ′ are formed in the central portion of the upper surface so as to be arranged in a staggered manner in the longitudinal direction as shown in FIG.

  On the other hand, the second nozzle plate support member 15b is formed with a slit-like opening 15b 'extending in the longitudinal direction at a portion corresponding to the recessed portion 15a' as shown in an enlarged view in FIG. The cross section of the slit-shaped opening 15b 'has a vertically long rectangular cross section on the opposite side of the recessed portion 15a', and a trapezoidal cross section that continuously expands downward at the lower end thereof. The portion of the second nozzle plate support member 15b where the slit-like opening 15b ′ is formed is formed in a thin portion 15b ″ having a predetermined width compared to the other portions, and the first nozzle facing the thin portion 15b ″. The lower surface of the plate support member 15a has a protruding portion 15c that fits into the thin portion 15b ″.

  The nozzle plate 16 is formed of an elongated thin plate piece having a size and a shape to be fitted into the thin wall portion 15b ″, and a plurality of nozzle plates 16 formed in a row or in a row in the longitudinal direction at a predetermined pitch at the center in the width direction. 3 and 5, the first nozzle plate support member 15a brings the upper surface of the first nozzle plate support member 15a into close contact with the cut surface 11a of the nozzle holder 11. In this state, the nozzle plate 16 is fixedly integrated by welding.The nozzle plate 16 has a mating surface between the protruding portion 15c of the first nozzle plate support member 15a and the thin portion 15b ″ of the second nozzle plate support member 15b. The first nozzle plate support member 15a and the second nozzle plate support member 15b are bolted through the O-ring 20 while being sandwiched between them. It is firmly supported by being fixed to the hermetically by one. Accordingly, the nozzle plate 16 can be easily removed by removing the bolts 21, so that cleaning and replacement can be easily performed.

  The nozzle hole 16a is not limited to a simple cylindrical shape, but may have a shape as shown in FIGS. As for the shape of the nozzle hole 16a shown in FIG. 7, the upper part is an inverted frustoconical shape, and the lower part continuing to the inverted frustoconical shape is formed in a cylindrical shape. When this hole shape is adopted, as shown in the figure, when the height of the cylindrical shape is L and the diameter of the cylindrical shape is D, the value of L / D can be set to 1-2. It is desirable from both sides to ensure good convergence and to enable high-precision drilling.

  In FIG. 8, a groove having an inverted trapezoidal cross section is formed on the upper surface of the nozzle plate 16, and a large number of cylindrical holes are formed on the bottom surface with a predetermined pitch in the length direction. Is excised. If the tip ridge line portion of the protruding cylindrical hole is processed into an arc shape at this time, the surface fibers of the fiber cloth will not be disturbed even if the nozzle hole 16a is brought into contact with or close to the fiber cloth during the ejection. The shape of the nozzle hole 16a shown in FIG. 9 forms a ring piece 16a 'that extends concentrically from the peripheral edge of the lower end of the cylindrical hole inward. By adopting such a hole shape, the high-pressure steam ejected from the nozzle hole 16a becomes a focused flow.

  According to the pressurized steam jet nozzle 10 having such a configuration, as will be described later, for example, when high-temperature and high-pressure steam is jetted from the pressurized steam jet nozzle 10, steam is introduced from one end of the pipe-shaped nozzle holder 11 during startup. If the steam is discharged from the other end, the high-temperature and high-pressure fresh steam passes through the inside of the nozzle holder 11 without any obstruction, so that the temperature of the nozzle holder 11 whose temperature has decreased is raised to a predetermined temperature in a short time. Can be made. This is because when the nozzle holder is provided with only a steam introduction opening as in the prior art, even if fresh high-temperature and high-pressure steam is introduced into the nozzle holder, the steam does not circulate inside the nozzle holder. Since it only fills the inside, the amount of heat is not exchanged and vapor condensation is likely to occur, and it takes a long time to raise the temperature of the nozzle holder.

  FIG. 10 shows a second structural example of the pressurized steam jet nozzle 10 according to the present invention. The difference between the second structure example and the first structure example described above is the structure of the first nozzle plate support member 15a fixed to the cut surface 11a of the nozzle holder 11 by welding. According to the second structural example, the through holes 15a ″ arranged in a staggered manner are eliminated from the first nozzle plate support member 15a, and the recessed portion 15a ′ is formed in the cut surface 11a of the nozzle holder 11 as it is. In the case of high-temperature and high-pressure steam, when the vapor pressure in the nozzle holder 11 is in a stable state, there is almost no fluctuation in the pressure distribution in the length direction. On the contrary, the presence of the through hole 15a ″ disturbs the steam flow. Further, since a large number of through holes 15a ″ are eliminated from the first nozzle plate support member 15a, the structure is simplified and the processing is also simplified.

  FIG. 11 shows a third structural example of the pressurized steam jet nozzle 10 according to the present invention. The difference between the third structural example and the first structural example described above is that the periphery of the nozzle holder 11 is encapsulated by a cylindrical jacket 22 having an open bottom surface, and the opening end portion of the third structural example is the first nozzle. The plate support member 15a is fixed by welding. By supplying a heating medium such as steam or a heat medium into the cylindrical jacket 22 and heating it, it is possible to prevent partial condensation of the steam from occurring inside the nozzle holder 11 due to the cooling action by the outside air. It is also effective to use an electric heater or the like instead of the cylindrical jacket 22 for heating.

  FIG. 12 shows a fourth structural example of the pressurized steam jet nozzle 10 according to the present invention. The difference between the fourth structure example and the third structure example is fixed to the cut surface 11a of the nozzle holder 11 by welding in the same manner as the difference between the first structure example and the second structure example. The first nozzle plate support member 15a has the structure. According to the fourth structure example, the through holes 15a ″ arranged in a staggered pattern are excluded from the first nozzle plate support member 15a in the third structure example, and the recessed portion 15a ′ is removed as it is. It communicates with a slit-shaped opening 11b formed in the surface 11a, which has the above-described function of the third structure example in addition to the function of the second structure example.

  In the above embodiment, an example is given in which a plurality of nozzle holes 16a formed in the nozzle plate 16 are arranged in a line. However, in the present invention, a large number of nozzle holes 16a formed in the nozzle plate 16 are provided. Further, as shown in FIGS. 13A and 13B, they can be arranged in two or more rows. As described above, when the nozzle holes 16a are arranged in, for example, two rows, it is preferable that the nozzle holes 16a arranged between the rows are arranged in a staggered manner with a ½ pitch shift. When the nozzle holes 16a are arranged in a staggered pattern, the pitch is substantially reduced as a whole even if the pitch between the nozzle holes 16a on the same row is longer than that in the case of a single row. The pressurized steam ejected from the nozzle 10 is uniformly applied in the width direction of the fiber fabric to be transferred, and the moire pattern is hardly attached.

  FIGS. 14-18 has shown 2nd Embodiment of the said pressurized steam injection nozzle which is the characteristic structure part of this invention. In this embodiment, the difference from the first to fourth structural examples is that the nozzle member 23 is composed of divided pieces of the first and second nozzle plate support members 15a and 15b as in the above embodiment. Instead, it is composed of a single member, and the nozzle hole 26 is directly formed in the nozzle member 23. Therefore, the nozzle plate 16 as a separate body is not required as in the above-described embodiment.

  On the upper surface of the nozzle member 23 according to the second embodiment, a ship-shaped recessed groove portion 24 that communicates with a slit-shaped opening 11b formed in the center of the lower surface of the nozzle holder 11 and extending in the longitudinal direction. A groove 25 having a rectangular cross section formed along the bottom, a number of inverted frustoconical holes 26a formed at a predetermined pitch along the length direction of the rectangular cross section groove 25, and a lower end of each reverse frustoconical hole 26a And a cylindrical hole 26b formed continuously. The inverted truncated cone hole 26a and the cylindrical hole 26b constitute the nozzle hole 26 in this embodiment. Furthermore, the external shape of the nozzle member is an elongated rectangular shape in a front view, and has a curved shape in which a lower surface protrudes downward in a side view (see FIG. 16).

  As described above, the nozzle member 23 according to the present embodiment is configured as a single member, and the nozzle member 15 is configured separately from the nozzle plate 16 as in the above-described embodiment, and the nozzle member 15 is also configured as the first and second nozzle members. Since the nozzle plate support members 15a and 15b are not divided, the number of parts is reduced, and the complexity of the assembling work is eliminated. In particular, in the first embodiment, the nozzle hole 16a is formed in the nozzle plate 16, and the surface facing the fiber fabric is not formed directly in the ejection side opening of the nozzle hole 16a but in the second nozzle plate support member 15b. In this embodiment, since the nozzle hole 26 can be directly opposed to the fiber cloth, the gap between the ejection opening end of the nozzle hole 26 and the fiber cloth is arbitrarily set. And more efficient fabric processing can be realized.

  Further, according to the present embodiment, since the concave groove portion 24 of the ship shape and the groove portion 25 having a rectangular cross section formed along the bottom of the concave groove portion 24 are formed in the same nozzle member 23, steam loss is reduced. Furthermore, since the nozzle member itself has a curved shape (see FIG. 16) in which the lower surface protrudes downward, the contact area with the fiber fabric can be reduced when the fiber fabric travels, and the fiber fabric travels more. To be smoothed. Also in this embodiment, similarly to the first embodiment, it is desirable to set the value of the ratio between the height and the inner diameter of the cylindrical hole 26b to 1 to 2, and the diameter of the cylindrical hole 26b is The pitch between the nozzle holes 26 is set to 0.1 to 1 mm and 0.2 to 3 mm.

  FIG. 19: has shown the outline | summary of 2nd Embodiment of the process process by the pressurized steam of the fiber fabric based on this invention. In this embodiment, the difference from the processing method is that a second endless belt 34 that rotates in the opposite direction to the endless belt 30 facing the fabric transfer surface of the endless belt 30 that is a cloth carrying and transferring means is provided. The superheated steam that is disposed and transported with the fiber fabric T sandwiched between the first and second endless belts 30 and 34 and ejected from the pressurized steam ejection nozzle 10 is passed through the second endless belt 34. This is a point directed from the upper surface of the fiber fabric F toward the endless belt 30 below.

  As described above, when the pressurized steam is applied to the web surface while the fiber fabric T is sandwiched between the two endless belts 30 and 34, the pressurized steam is ejected from the pressurized steam ejection nozzle 10 by the blow. In this case, the surface of the fabric is not disturbed, and as a result, the pressure of the pressurized steam ejected from the pressurized steam ejection nozzle 10 can be further increased, and the steam flow ejected at a high pressure ensures the fiber fabric T. Will be able to penetrate. In this embodiment, the porosity (mesh degree) of the second endless belt 34 facing the upper surface of the fiber fabric T is set to be coarser than that of the lower endless belt 30, but it is not necessarily rough. An equivalent porosity can also be set.

  FIG. 20 shows an outline of a third embodiment of the treatment process of the fiber fabric according to the present invention using pressurized steam. According to this embodiment, when the pressurized steam jet nozzle 10 and the suction box 40 arranged to face the nozzle 10 are set as one set, the plurality of sets (two sets in the illustrated example) are fiber fabrics T. Further, the arrangement of the pressurized steam jet nozzle 10 and the suction box 40 in each set is reversed upside down. That is, the pressurized steam jet nozzle 10 is disposed with the nozzle hole 16a of the first set of pressurized steam jet nozzles 10 facing the upper surface of the fiber cloth T, and the suction opening of the suction box 40 is formed from below the fiber cloth. A suction box 40 is disposed toward the lower surface of the endless belt 30 that carries the fiber fabric. On the other hand, the second set of pressurized steam jet nozzles 10 are arranged with the nozzle holes 16a facing the lower surface of the endless belt 30 carrying the fiber fabric T from below, and the suction box 40 includes The suction opening is disposed toward the upper surface of the fiber fabric T.

  In this way, when the pressurized steam is jetted alternately from the pressurized steam jet nozzle 10 toward the upper surface and the lower surface of the fabric T that is carried and transferred by the endless belt 30, the fiber The pressurized steam acts equally on both the front and back surfaces of the fabric T, and the constituent fibers or yarns of the fabric T are easily and easily treated on the front and back surfaces of the treated fiber fabric T. There is no distinction between the front and back, and the product value is improved.

  FIG. 21 shows an outline of the main part of the most preferred fourth embodiment in the process step of the fabric according to the present invention. Reference numeral 23 in the figure denotes a nozzle member of the high-pressure steam jet nozzle shown in FIGS. 13 to 18, a fiber cloth is arranged close to the lower surface of the nozzle member 23, and is supported on an endless belt 30 as a fiber cloth transfer means. Then, high-pressure superheated steam is ejected to the surface of the fiber cloth through the nozzle hole 26 of the nozzle member 23 during the transfer of the fiber cloth T transferred. A suction box 40 serving as a suction means is disposed in the vicinity of the inner surface of the first endless belt 30.

  In this embodiment, the suction opening of the suction box 40 is disposed at a position facing the nozzle hole 26 of the nozzle member 23, and the shape thereof is a slit shape so as to avoid suction of surrounding gas as much as possible. In many cases, the opening width of the slit opening is preferably about 10 mm, and the exhausting capacity of a ventilation fan used in a normal factory, that is, about 300 Pa is sufficient. It tends to give orientation to the fiber, and if it is smaller than that, it tends to be insufficient in suction force. Of course, it is necessary to adjust this suction force within a required range depending on the thickness and density of the fiber fabric T and the vapor pressure when ejected from the nozzle member 23.

  In this embodiment, in order to maintain the gap between the nozzle member 23 and the fiber fabric T and the gap between the first endless belt 30 and the suction box 40, a plurality of supporting and guiding the lower surface of the first endless belt 30 is provided. The support rotation roll 35a is provided. By providing these support rotating rolls 35a, it is possible to avoid the sliding contact between the endless belt 30 and the suction box 40, and at the same time keep the facing gap minute. Note that these supporting rotary rolls 35a can be adjusted using known vertical position adjusting means.

  FIG. 22: has shown the outline | summary of 5th Embodiment of the processing apparatus of the textile fabric which concerns on this invention. In this embodiment, a porous rotating drum 36 is employed as a means for carrying and transferring the fiber fabric T. A fiber fabric T is introduced into the rotary drum 36 via an endless belt 37, a guide plate or a guide roll (not shown), and the fiber fabric T is guided along the peripheral surface of the rotary drum 36 to rotate corresponding to a required central angle. It is sent out to the discharge side while circling the peripheral surface of the drum 36.

  On the other hand, the high-temperature high-temperature steam ejected from the pressurized steam ejection nozzle 10 disposed in the vicinity of the upper surface of the fiber fabric T enters the fiber fabric T transferred by the rotary drum 36, The fiber fabric T penetrates between constituent fibers or yarns and is discharged to the outside through a suction box 38 installed inside the rotary drum 36. The suction box 38 has a suction port 38a formed in a slit shape that is equal to the width dimension of the fiber fabric T and is long in the width direction, and performs efficient suction. The width dimension of the suction port 38a is preferably about 10 mm, as in the fourth embodiment described above, but changes to some extent depending on the thickness and density (void ratio) of the fiber fabric T or its material. Is possible. The suction port 38a of the suction box 38 is located at a position facing the nozzle hole 16a of the pressurized steam jet nozzle 10, and is fixed in the vicinity of the inner wall surface of the rotary drum 36. The sucked steam is not shown. It is discharged to the outside through a discharge path formed at the center of the rotation shaft of the rotary drum 36 via the swivel joint.

  In the present embodiment, a pressurized high-temperature air ejection device 39 is further installed on the upstream side of the pressurized steam ejection nozzle 10 above the fiber fabric T, and inside the rotating drum 36. A second suction port 38b is formed on the upstream side of the suction port 38a of the arranged suction box 38 and at a site corresponding to the pressurized high-temperature air ejection device 39. The shape and dimensions of the suction port 38b are substantially the same as those of the suction port 38a, but the ejection pressure of the hot pressurized air ejected therefrom is set to be smaller than the ejection pressure from the pressurized steam ejection nozzle 10. In addition, the size of the nozzle hole (not shown) may not be set strictly. The pressurized steam jet nozzle 10 may be employed in place of the pressurized hot air jet device 39.

  When the pressurized high-temperature air ejection device 39 is arranged on the upstream side, the application of the pressurized air to the fiber fabric T is different from the application of the pressurized steam, and the pressurized air is applied prior to the application of the steam. Then, the fiber fabric T is dry-heat set, and after the surface form of the fiber fabric T is fixed in advance, various processes are efficiently and reliably performed by the pressurized steam ejected from the pressurized steam ejection nozzle 10. Will be made. The nozzle member shown in FIGS. 3 to 18 can also be used as the nozzle member of the pressurized high-temperature air ejection device 39 used in the present embodiment, and the pressurized steam ejection nozzle in this embodiment. The circuit illustrated in FIG. 1 and FIG.

  In the embodiment described above, the nozzle hole 16a of the steam-pressurized steam ejection nozzle 10 is simply disposed toward the fiber fabric T. However, in the present invention, the entire pressurized steam-ejection nozzle 10 is further disposed. It can also be actively heated to maintain a high temperature. FIG. 23 shows an example. According to the figure, a heating box 27 that accommodates the entire pressurized steam jet nozzle 10 including the nozzle holder 11, the nozzle plate support member 15, and the nozzle plate 16 is used. The heating box 27 is formed of an elongated rectangular parallelepiped that accommodates the entire pressurized steam jet nozzle 10 and has the entire surface opened on the side to which the nozzle hole 16a of the pressurized steam jet nozzle 10 is directed. The hot air inlet 27b is formed in the upper part. The hot air inlet 27b is connected to an external hot air supply pipe 28. The high temperature purified air introduced through the filter 28b by the fan 28a and heated by the heater 28c is sent to the heating box 27 through the hot air supply pipe 28, and the pressurized steam jet nozzle 10 is supplied. The whole is actively heated with hot air.

  In this way, by heating the entire pressurized steam jet nozzle 10, temperature drop of the pressurized steam and superheated steam introduced into the nozzle holder 11 is effectively prevented, and the required temperature is maintained and applied. It can be made to eject toward the fiber fabric T from the pressure steam ejection nozzle 10. As a result, not only can the amount of steam used be reduced, but at the same time, efficient fiber entanglement can be realized, and the form of the fabric to be treated can be stabilized and desired strength and texture can be obtained.

  Moreover, according to the example of illustration, it exists in the front-and-back wall surface 27a, 27b of the fiber fabric transfer direction of the superheat box 27, Comprising: The peripheral surface of the seal rolls 29a, 29b is contact | abutted to the lower end part. These seal rolls 29a and 29b are stainless steel smooth rolls or rolls coated with resin on the peripheral surface, and may be free rotating rolls or driven and rotated in synchronization with the transfer speed of the fiber fabric T. Good. By providing such seal rolls 29a and 29b, it is possible to prevent the escape of hot air from the overheating box 27 and at the same time prevent the intrusion of outside air, and the heating efficiency for the pressurized steam jet nozzle 10 is improved.

  In this example, the endless belt 30 is further provided with an outside air shielding plate 63 having an opening corresponding to the suction opening of the suction box 40 disposed opposite to the endless belt 30 which is a carrying and conveying body of the fiber fabric T. And the suction box 40. The front and rear end portions of the outside air shielding plate 63 in the fiber fabric transfer direction are curved downward so that the passage of the fiber fabric T is smoothly stabilized. In this way, by interposing the outside air shielding plate 63 between the endless belt 30 and the suction box 40, the outside air enters the ejection area of the pressurized steam or superheated steam ejected from the pressurized steam ejection nozzle 10. The fiber fabric T passing between the pressurized steam jet nozzle 10 and the suction box 40 is not affected by outside air, and the loss of thermal energy is greatly reduced. Therefore, efficient continuous processing is performed.

  FIG. 24 shows a further modification of the steam processing apparatus. According to this modified example, the vapor reflecting plate 64 is interposed between the endless belt 30 and the suction box 40 in the same manner as the outside air shielding plate 63. The difference between the vapor reflecting plate 64 and the outside air shielding plate 63 is that the outside air shielding plate 63 has an opening extending in the column direction of the nozzle holes 16a at the center and is formed on a smooth surface. On the other hand, the vapor reflecting plate 64 is made of a porous plate material. Now, when the pressurized steam or superheated steam ejected from the pressurized steam ejection nozzle 10 passes through the second endless belt 34, the fiber fabric T, and the first endless belt 30, a part of the steam is sucked by the suction box 40. However, most of the light is reflected by the vapor reflecting plate 64 and acts again on the lower surface of the fiber fabric T, so that the surface on the lower surface side of the fiber fabric T is equally processed.

  Further, in the present invention, the pressurized steam jet nozzle 10 is reciprocated slightly in the longitudinal direction thereof, or the first and second endless belts 30 and 34 are crossed along the fiber cloth transport path together with the fiber cloth. It can be reciprocated minutely in the direction. A driving mechanism for the reciprocating motion is not shown in the figure, but a conventionally known mechanism for applying lateral vibration to a net such as a long net paper machine can be employed. Further, the stroke of reciprocation (vibration) is preferably about 5 mm to the left and right from the center of reciprocation, and the number of reciprocations is arbitrarily adjusted in the range of 30 to 300 times / min. As described above, when the pressurized steam ejection nozzle 10 or the first and second endless belts 30 and 34 are reciprocated, the pressurized steam or superheated steam ejected from a large number of nozzle holes arranged in a row is obtained. The surface of the fiber fabric T acts evenly in the width direction, and even when high-pressure steam is ejected from the pressurized steam ejection nozzle 10, a moire-like pattern is not formed on the fabric surface, and a more uniform treatment is performed. Made.

  By the way, the processing method using the high-temperature and high-pressure steam ejected from the above-mentioned pressurized steam ejection nozzle includes the processing conditions such as the transfer speed of the fabric, the steam temperature and the vapor pressure, the gap between the fabric and the ejection opening end of the nozzle, and the fabric. Types (woven fabrics, knitted fabrics, non-woven fabrics, etc., alone or in combination), fabric structure (woven / knitted structure, woven / knitted density, non-woven fabric fiber density), fabric constituent fiber or yarn material, fabric thickness By appropriately combining the fabric conditions such as the above, various fabric treatments as described below can be performed efficiently. However, since these treatments are determined for each type of treatment from the above-mentioned many treatment conditions and fabric conditions, it is difficult to uniformly determine those conditions.

  According to the method for steam treatment of a fabric according to the present invention, naturally, normal heat setting is also possible, but in particular, for example, fabric washing treatment and decoloring treatment, fabric drainage treatment after liquid treatment, fabric texture improvement treatment. Furthermore, various chemical treatments can be performed on the fabric. Among these examples, steam heat treatment is sometimes performed for heat setting, fabric texture improvement, etc., but fluid treatment is generally employed for other treatments. In addition, even in the steaming heat treatment, the fabric is placed in a high-temperature steam atmosphere or is treated through the same atmosphere.

  On the other hand, as described above, the steam treatment method for a fabric according to the present invention ejects high-temperature and high-pressure pressurized steam (gas) from a pressurized steam ejection nozzle toward the fabric and penetrates the fabric as described above. It is intended to perform various processes. Therefore, the heating steam treatment ejected from the pressurized steam ejection nozzle of the present invention and the conventional steaming heat treatment are the same in terms of the use of steam, but of course the construction and the functions and effects are completely different. It is.

  That is, in the above-described washing treatment, by simply applying pressurized steam, naturally the dirt during the treatment in the previous step as in the prior art or the excess dye remaining on the fabric after dyeing is coarsened by the washing liquid or water. It can be removed in the same manner as flowing, and it is also possible to reliably remove deposits such as glue, oil, and various resins adhering to the fabric or its constituent fibers. This is unexpectedly applied when pressurized steam penetrates the fabric without being affected by the material of the adhered material, such as glue, oil, and various resins that adhere to the fibers and yarns constituting the fabric. This is because the kimono is instantaneously blown out of the fabric with the same steam. Moreover, in the present invention, since the vapor (gas) treatment is used instead of the liquid treatment, the treatment can be performed without adhering moisture to the fibers and yarns constituting the fabric. There is also no need to pass through a removal step of solvent and solvent. This leads to a significant reduction in equipment costs and energy costs.

  In addition, the above decolorization treatment is performed by, for example, removing a part of the dyeing after a uniform dyed product such as denim clothing, or when the product becomes an original fabric. This decolorization often uses a decolorizing agent, and even the fabric may be damaged. However, even when the pressurized steam treatment method of the present invention is adopted, such partial decoloring treatment can be performed without using a decoloring agent again, and at the same time, the fabric is not damaged.

  Further, for example, in the liquid removal treatment for the fabric after the liquid treatment, the fabric is impregnated or adhered with a large amount of the treatment liquid in the previous step, similarly to the washing treatment. If the method of the present invention is carried out in this state, while the pressurized steam ejected from the pressurized steam ejection nozzle penetrates the fabric, the liquid impregnated or adhered to the fabric evaporates or volatilizes at the same time as the steam. And blown out of the fabric. That is, since the liquid component can be efficiently removed from the fabric in the same manner as the normal drying step, the method of the present invention may be applied instead of the conventional drying step. In this case, the conventional drying process requires a large drying chamber as basic equipment, and further, for example, a large number of heating lamps, heating drums or heating rolls are arranged inside the chamber, and these heating lamps and heating drums are arranged. Alternatively, a supply facility for electrical energy or fluid energy is connected to the heating roll, and at the same time, an exhaust facility is arranged. Drying in the drying chamber is extremely low in drying efficiency because of its large heat capacity, and it takes a long time to dry, and naturally enormous amount of heat energy is consumed.

  On the other hand, in the dewatering method according to the present invention, the large chamber as described above is unnecessary, and the nozzle is ejected from the nozzle onto the fabric that is simply transferred from the pressurized steam ejection nozzle connected to the steam supply facility. The liquid component impregnated in the fabric fibers or yarns can be removed to the outside simply by applying the pressurized steam, and even if the liquid component remains inside the fabric, Immediately after passing through the liquid removal step, the fabric is maintained at a high temperature by steam heating, and drying of the fabric is accelerated by the heat. At this time, since the heat energy used is piping or a pressurized steam jet nozzle which is a very narrow space, the energy application efficiency is extremely excellent. As a result, the amount of energy used is also small compared to the prior art.

  In addition, the method for improving the texture of the fabric can employ the method of the present invention in place of a texture improving treatment such as a washing method or a steaming method for a conventional wool fabric or knitted fabric. According to the method of the present invention, it is not necessary to wind up the fabric in advance before the treatment as in the conventional washing method or steaming method, and the surface is clogged continuously and in a short time, and the surface is soft. A rich and excellent wool fabric can be obtained efficiently.

  Further, in the present invention, the chemical treatment may be performed by further joining a chemical injection path to the vapor introduction path of the nozzle holder and ejecting the chemical together with the pressurized vapor to the fabric. The chemicals at this time include fragrances, deodorants, insect repellents, etc., and the chemicals merge with the pressurized steam flowing through the nozzle holder's vapor introduction path to the nozzle introduction opening and dispersed there. It is introduced into the inside of the holder, and is ejected along with the steam toward the surface of the fabric through the nozzle hole. This chemical also penetrates the fabric together with the vapor, adheres to the surface of the constituent fibers of the fabric or between the fibers during the penetration, or penetrates into the constituent yarn or adheres to the surface of the yarn, and the desired chemical treatment is performed. It is made uniform throughout the fabric.

  As described above, according to the method of the present invention, high-temperature and high-pressure steam can be more surely penetrated into the fiber fabric in spite of the pressurized steam jet nozzle having the simple structure as described above. In addition to opening both ends in the longitudinal direction of the nozzle holder, especially when the opening on the vapor discharge side can be opened and closed by an opening / closing valve, and the trap pipe is branched upstream of the opening / closing valve The opening / closing valve is opened in advance at the start of the processing of the fabric, fresh pressurized steam is introduced into the pressurized steam jet nozzle, and the pressurized steam is discharged to the outside through the steam discharge side opening. As a result, the internal temperature of the nozzle holder rapidly rises, so that the preparation time at the start of the fabric treatment can be greatly shortened.

  When the processing of the fabric is started, the opening / closing valve is closed, but the drain generated inside the nozzle holder is always collected from the opening on the vapor discharge side through the trap pipe to the collection tank. There is no adverse effect such as clogging, and a high-quality fabric can be processed continuously and stably. In the above embodiment, superheated steam is used as the steam, but normal steam may be used depending on the material of the constituent fiber of the fiber fabric.

  As described above, the processing conditions such as the transfer speed of the fabric, the temperature and pressure of the pressurized steam, the fabric type such as woven fabric, knitted fabric or non-woven fabric, and the fabric conditions such as the fabric structure can be appropriately combined. For example, it is possible to efficiently perform various treatments of the fiber fabric, such as washing with ordinary liquid, drying, decolorization, improvement of texture by steaming, and chemical treatment.
