Abstract

A technique for a reciprocal hydrometer is presented which includes a pair of fabric reels with a hydrophobicity process arranged intermediate. The hydrometer process is configured to impart a minimum amount of hydrometering to the fabric that passes through it and may comprise a single vacuum roller and associated with a single stream of hydrometer (other arrangements can be used with two or three vacuum rolls and jets with the object of providing controllable treatments by the front or the back side for each step). The fabric to be treated is first loaded on a first reel, goes through the process of hydrometer and is taken on the other reel, on the whole length of the fabric has been treated and loaded on the second reel and is now inverted or made work in reverse, the fabric leaves the second reel and becomes entangled in the first, the process is reversed and a second forward movement of the fabric is made. This will be a reciprocal movement until the desired degree of hydrometer is reached. Measurement units, such as a permeability measuring system, can be used to evaluate the hydrometer at each step, thus controlling the different parameters, as well as stopping the process.

Description

«*" RECIPROCAL HYDROMBLER SYSTEM DESCRIPTION OF THE INVENTION The present invention relates to a reciprocal hydrometer system, and more particularly to a hydrometer apparatus and method that provides efficiency and increased flexibility in the textile finishing capacity, and also provides a reduction in size compared to the systems of Hydrometer standards. In conventional hydrotreated processes, the carrier webs of the nonwoven fibers are treated with high pressure fluids, while they are supported on a wire coupling substrate. Typically, the wire of the substrate is provided on a drum or a flat continuous conveyor that is pierced by a series of pressurized fluid jets to gather the fabric into cohesively ordered fiber groups and configurations corresponding to open areas on the screen, Xa stirring is effected by the series action of fluid jets that cause the individual fibers in the fabric to migrate to open areas in the area of the screen, mix or combine. The hydrometer is a term used to describe the process of hydroconfusion that is used specifically in a woven fabric, in the hydrometer, the properties of a woven fabric are modified or improved by exposing the fabric to a sequence of high pressure jets which act on the fabric, the yarn fibers that form the fabric. During the improvement process, the fibers of the same or adjacent yarns are mixed thereby changing the properties of the fabric, (usually resulting in a decrease between the open spaces between the warp yarns and the weft yarns). In a conventional continuous process of the hydrometer system, a relatively large number of pressurized water jets is required to provide the required amount of hydrometer in a single step. For example, it would not be an extraordinary thing for a hydrometer system to require 6 to as many as 20 separate pressurized water jets to achieve the desired degree of hydrometer. As a consequence, the number of "active" jets, the associated water pressure and the speed of the manufacturing line must be modified frequently for different fabrics that are passed through the system. In general, it can be assumed that an exemplary hydrometer system is designed, so that it is capable of providing the maximum degree of hydrometer in a single step, and the system must be backed up or decreased (for example by shutting down one or more jets, reducing the speed of the line or reducing the precession of the stream of water that leaves with the jets), during any situation where a lower degree of hydro ejora is required.

Limitations associated with prior art arrangements include the large floor space that is needed to form a hydrometer process line that is sufficient to reach the maximum hydrometer value, which has been described above. In addition, if any fabric requires a degree of improvement beyond the design of the original equipment, the entire line line must be modified (that is, more jets will need to be added), or the fabric will have to be completely reprocessed (this is to go through the whole hydrometer line a second time). Additionally, the maximum nature of the system is in "excess" for many applications, either for small runs of material or applications where a minimum degree of hydrometer would be required. In these situations, the overall efficiency of the process (compared to the size of the processing line) is too low. Finally, the continuous nature of conventional hydrometer systems is problamatic in the development of new hydrodynamic fabrics, since the ability to test the required degree of hydrometer to be imparted to a given fabric is virtually non-existent. Therefore, there is a need in the art for a more robust hydrophobic process that essentially imparts the proper degree of hydrometer for woven materials, and at the same time be more efficient and economical when used. The present invention concerns a reciprocal hydrometer process that uses a minimum number of jets under pressure arranged between a pair of reciprocal coils controlled by tension. According to the present invention, a or b of the coils can be replaced by a tension controlled structure or frame A or any suitable means for supporting the fabric, where the A-frame is a structure that is generally used in the industry for transporting the fabric during processing, the fabric is loaded on the first spool or reel, it is passed under the jet or jets of hydrometer and is received on the second spool (this defines a first or front step through the system). Once the entire length of the fabric has been wound on the second reel, the process is reversed, that is, the fabric is unwound from the second reel, passed under the jet or jets of hydrometer and is received in the first reel ( which defines a second or reverse step through the system). This reciprocal process is repeated back and forth until the required degree of hydrometer is acquired. Thus, the fabric is contained within the hydrometer system until the appropriate degree of hydrometer is obtained. In one embodiment of the invention, the hydrometer of the fabric can be measured using a process such as that presented in my co-pending application NO series. 922,412, and is used as a control signal to stop the hydrometer process when the proper degree of hydrometer is achieved (indicated for example by a predetermined decrease in the permeability of the fabric). Additionally, the reciprocal nature of the present invention allows the degree of hydrometer to be modified on a basis of each step. Therefore, several parameters of the process including but not limited to line speed, fabric tension, number and location (of inido as identity), of the jets active in the set of hydrometer jets and hydrosmera energy ( defined by the pressure of the liquid that leaves the hydrometer jets), can be modified in each step to provide any desired hydrometer result in the final product. It is an aspect of the present invention that the spools and jets can be configured, so that the "front side" hydrometer (F), and the "back side" (B), can be made in any desired sequence. For example, a front treatment and a back treatment may be performed at each front step (a FB sequence), and an inverse step (a BF sequence), resulting in a series of steps characterized as FB-BF-FB-BF- FB, which can be replaced until the required degree of hydrometer is achieved. Alternatively, a frontal side treatment can be performed in each forward step, and a back side treatment in each reverse step, which is mentioned as an alternate step system (this is FBBFB ..) »In general, any combination is possible and is considered to be included within the scope of the present invention. Thus advantageously any number of suitable steps can be made through the apparatus. Additionally, compared to conventional hydrometer arrays, the apparatus of the present invention requires a minimum floor space only the space needed for a pair of reels and a limited number of hydrometer jets and associated equipment. In fact, a reciprocal example hydrometer system can include only a single jet and an associated fabric support system (eg, vacuum roll or moving wire system), a system for performing both the front side and the front side hydrometer. back side can be formed using only two or three jets (each jet having its own fabric support system), depending on how the jets are controlled. It is an advantage of the reciprocal movement hydrometer arrangement arrangement, what additional processes can be carried out simultaneously with the hydrometer process (this is without moving the fabric to another machine), for example, an acid bath (or any suitable process of pretreatment or post-treatment), can be added before or after or simultaneously inside a hydrometer unit, allowing two or more separate determination processes simultaneously, improving the overall efficiency of the line line with reduced product handling. It is to be understood that the reciprocal process which will be described in detail below may also be used in certain circumstances to provide brokering on non-woven materials. In such cases, the non-woven material will require sufficient strength to resist the nature back and forth of the reciprocal process, without stretching or breaking. Other features and aspects of the present invention will become apparent during the course of the following description with reference to the accompanying drawings. DESCRIPTION OF THE DRAWINGS FIGURE 1 illustrates an exemplary reciprocal arrangement of hydrometer of the present invention, utilizing a single pressurized jet; FIGURE 2 illustrates an alternative embodiment of the invention for providing both front and rear side hydrometers using a pair of pressurized jets; FIGURE 3 illustrates a variation of the arrangement of the Fig. 2, configured to include an additional processing step in serié with the hydrometer process; FIGURE 4 illustrates another reciprocal hydrometer system arrangement using a movable wire conveyor in place of the vacuum roller presented in Figs. 1-3, and formed to include a set of three jets under pressure for hydromera; and FIGURE 5, presents a modality that uses a set of three associated vacuum jets and rollers, where the three jets are controlled to provide a suitable pattern for the front and rear side process. Figure 1 illustrates a relatively simple reciprocal hydrophobic system according to the present invention, the system 10 receives the woven fabric 12 from a main roll, where the woven fabric 12 is initially loaded on a first reel 14 so that the entire length of the fabric to be subjected to hydrometer has been loaded onto the reel 14. Alternatively, the first reel 14 can simply comprise a portable main roll (such as a frame A) which can subsequently be used to transfer the hydro-enhanced product to another. The first reel 14 includes a permanent or semi-permanent grip guide which provides a means for attaching a cloth 12 to the first reel 14, wherein the guide is of sufficient length to accommodate complete improvement of the fabric, preferably the guide The grip is formed of a non-absorbent metal wire screen with respect to the dye material. The use of such a material as a grip guide allows it to be re-used as each new cloth reel is loaded. The fabric 12 then passes through a pair of tension adjusting devices 16, 18 9 cooperating with the reels 14 and 30 to control the speed of the line and the tension of the fabric during the hydrometer) and subsequently passes over a vacuum roller 20.If different tension adjustment devices are required, the reels 14 and 30 can be configured to directly sense and control the voltage. OR? Hydro-jet stream 22 is associated with the vacuum roller 20 and is used to impart a predetermined amount of hydrometer to the front side F of the fabric 12. For example a jet 22 can emit the liquid stream eg water, at a pressure determined, for example 3.5 kg per square centimeter and up to 420 kilograms per square centimeter. On the front side F of the fabric. Other liquids may be used. A recirculating liquid system 23 may be used in conjunction with the jet 22 and the vacuum roller 20 to provide a liquid. { in this case water) for the hydrometer process, In general, a water system 23 includes a pressurization module to create a predetermined pressure as mentioned. In addition, the water system 23 functions to filter the water back out from the vacuum roll 20. Filtration works to separate any fibers from the water before allowing the water to enter the pressurization module. If a dye is included in the water, the filtration system must be able to remove the filters without the temptation of the water. Such filtration systems are conventional and known in the art. A vacuum source would also be included in the system 23 to effect the movement of the water from the vacuum roller 20 and return it to the system 23. The jet 22 can be allowed to vibrate or oscillate slightly with respect to the roller 20, wherein this movement of the Jet 22 is known to carry a minimum or prevent any undesired pattern on the surface of the fabric being processed. Referring to Figure 1, once an exposed section of the fabric 12 has been subjected to a hydrometer treatment, it will pass through another pair of voltage controllers 24, 26 and. it will enter a metering unit 28. Generally speaking, the permeability of the fabric 12 is an indicator of the degree of hydrophobicity achieved, and a permeability measurement can therefore be used to control the reciprocal micro-brewing process. The control can simply be used to stop the hydrometer process once the proper degree of hydration has been achieved. Additionally, the evaluation performed by the measuring unit 28, can be used as described above and indicated by the lines interrupted in the Figures, to control step-based, one or more processes associated with the hydrometer process, for example, the speed of the line, the tension of the fabric, the hydrometer power, (this is the pressure of the liquid that leaves the stream of improvement) or the sequence of "quenching and ignition" of the jet can be controlled (either manually or automatically ) to impart the desired type of hydrometer to the finished product. Advantageously, the reciprocal nature of the present invention allows such modifications to be made theoretically at any step through the system. The previous systems of a single step did not have the capacity to make any such modifications in real time to the fabric that was being processed. An exemplary hydrometer measuring unit and a control system are presented in my co-pending application, which is incorporated by reference. N Upon leaving the measuring unit 28, the fabric 12 is taken on a second rail 30. Like the first rail 14, the second rail 30 may also include a permanent or semi-permanent guide to provide a means for joining the end of the tea * 12 to a second rail 30 to provide the fabric with an improvement coverage along its entire length, the use of the guide sections at each end of the fabric allow the total length of the product to be subjected to the hydrometer process . The speed at which the fabric 12 passes through the system 10, as well as the tension of the fabric, must be carefully controlled so that a uniform degree of hydrometer is imparted to the total length of the fabric 12. Therefore, the first spool and second 14 and 30, are equipped with suitable drive motors and control equipment (not shown) which are used to continuously control the line speed of the system and its voltage, and to adjust the winding and unrolling rates of the system. the reels conveniently. As discussed above, the speed and / or tension can be intentionally modified at any "step" by the system to impart a desired quality to the processed fabric. Any modification would only occur in a time interval between steps such that the parameters must remain fixed throughout the length of the fabric during processing at any particular step. Once the entire length of the fabric 12 has passed through the system 10, and taken on a second reel 30, the system is reversed or reversed and the fabric passes in the opposite direction, as indicated by the dotted arrows at Through the measuring unit 28, the controllers 26 and 24 are subsequently subjected again to hydrometer under the pressure jet 22 associated with the vacuum roll 20., the degree of hydrometer added to the fabric 12 during the reverse process can be measured by another second unit of hydrometer 32 (including control capabilities of the similar process parameter, as indicated by the interrupted lines). With the forward process, the reverse hydrometer continues until all the fabric has again been re-wound in the first reel 14. Depending on the hydrometer reading of the measuring unit 32, the process can again be repeated or stopped if has achieved enough hydrometer. Advantageously, the forward and backward nature of the reciprocal hydrometer process allows the fabric to be processed as many times as needed to achieve exactly the desired degree of hydrometer. therefore, instead of the conventional one-step technique, the hydrometer system which may require for example 6 to 20 separate jets (and the space and support of the water system associated with a large number of jets) The reciprocal system of the present invention can use as little as one jet per pass and perform 20 steps (or more or less, as desired) to achieve essentially the same degree of hydrometer as the conventional one-step system. The ability to control hydrometer per step is extremely useful during the processing of new fabrics, where the exact energy and line speed requirements can be ignored. In the prior art, the fabric should pass through the entire system and then be analyzed to see if too much hydro has been received or too little. obviously, there is a waste of cloth associated with such an experiment. In contrast, the reciprocal system of the present invention allows the tension of the fabric to be controlled, since the settings for the tension adjustment devices 16, 18 and 24, 26 can be controlled and re-adjusted at each step through the system. . In particular, the devices can be readjusted to maintain a constant web tension at each step, or alternatively intentionally increasing or decreasing the tension of the fabric to provide a special effect on the finished product. As mentioned above, it may be desirable to perform hydrometer both on the front co or on the back of the fabric. A reciprocal hydrometer system capable of providing back and front treatment is shown in Figure 2. This arrangement differs from that, of Figure 1, by the addition of a second vacuum roller 34 and the associated pressure jet 36. The roll vacuum 34 and jet 36 are disposed downstream of first vacuum roller 20 and jet 22 and positioned so that the back surface B of fabric 12 is exposed to the stream of water exiting jet 36, as shown in Figure 2. Although not shown, a water recirculation system, similar to system 23 of Figure 1 can be used in association with the vacuum and jet rolls of the arrangement of Figure 2. Referring again to Figure 2 , the fabric that leaves the second vacuum roller 34 has been subjected to hydrometer from a pair of jets 22, 36, performing the process on the front surfaces and (F) and back (B), respectively of the fabric 12. The fabric 12, then go through of the measuring unit 28, as described above in relation to Figure 1, and wound on the second reel 30. Once the entire length of the fabric has been subjected to the first step, hydrometer on both the front side F as in the back B of the fabrics (a sequence FB as defined above) and assuming that a sufficient degree of hydrophobicity has not been achieved (as measured by unit 28), the system will function as a reverse and the fabric 12 it will pass in the opposite direction, as indicated by the interrupted arrows. Again the fabric 12 will receive both a front and back treatment, passing first under the second hydro-jet stream 36 to receive a back treatment and then passing under the first hydro-jet stream 22 to receive a front treatment (a BF sequence as defined above). ) and finally re-rolling on the first reel 14. The reciprocal process will continue with a series of forward and backward steps of the fabric (ie FB-BF-FB-BF) until the measuring unit 28 (or the measurement 32, if applicable) indicate that the appropriate amount of hydrometer has been obtained. Since the reciprocal process can be easily controlled (either manually by an operator or automatically by a computer) any permutation of the process can be performed. For example, the system can be configured to perform front and rear hydrometer treatments (FB) at each forward step, (ie in the direction of the first roller 14 to the second roller 30) and only a frontal improvement F in each reverse step (this is in the direction of the second roller 30 to the first roller 14). Alternatively, a front treatment may be applied in the forward direction and a back treatment in the reverse direction (F-B-F-B ..). The flexibility associated with the reciprocal system in terms of process variation is significantly greater than would be possible with a conventional one-step system. For example, the process can be controlled by controlling the speed, that is to perform first a series of reciprocal steps at a speed and then perform another set of steps at a second speed. In the conventional system, it was impossible to make such a change in speed. Similarly, the tension of the fabric and the hydrometer energy (that is, the pressure of the liquid expelled from the jets, measured in kilograms per square centimeter) can be controlled or modified on the basis of each step or step. Another unique quality of the reciprocal arrangement is that the side to be treated with hydrometer can easily be controlled by opening or closing the different jets, as discussed below. In a conventional single-step design, there is no ability to stop the process and switch the side of the fabric that has to be subjected to the hydrometer process, changing the line speed, modifying the tension, etc. The variations of the system are endless, exemplary variations are discussed below with respect to Figure 5. Figure 5 illustrates an alternative embodiment of the present invention, wherein an additional processing step has been added in sequence with the hydrometer treatment. Any desired process of termination, whether a "preliminary processing" and / or a subsequent processing, can be included and increase the overall efficiency of the system by performing two (or more) essentially simultaneous operations. Referring to Figure 3, an acid bath treatment zone 40 has been inserted between the hydrometer measuring unit 28 and the second roller 30. Other processes may be inserted in an area 40, include but are not limited to, dyeing, washing , blanching or abrasion of the fabric 12. An additional zone 42, illustrated in phantom in Figure 3, can be inserted between the first roller 14 and the measuring unit 32 (or first vacuum roller 20, as the case may be) and used to provide a "treatment" to the fabric 12 (a non-liquid immersion treatment, for example an ultraviolet light treatment »or the spraying of an additive, could be appropriate), before it enters the hydrometer process. In general the system can be configured so that the fabric 12 passes through additional zones 40 and 42 in a single pass through the system 10 (and subsequently skips those zones) or alternatively travels through those zones at each step through of the system. The selection can be a design-only issue and the type of additional processing that has been introduced. Each of the reciprocal hydrometer systems described so far, has used a combination of vacuum roller and jet pressure to provide the hydrometer treatment. There are other arrangements capable of providing hydrometer that are viable alternatives for use in the reciprocal hydrometer system. In general any arrangement that allows the t'ela to be exposed to a stream of a liquid that comes out with a jet of pressure will be sufficient, any curved or flat surface, whether permeable or non-permeable with or without vacuum, may be appropriate. Figure 4, in particular, illustrates an exemplary hydrometer system, utilizing a movable wire conveyor arrangement 46, disposed between a first spool 48 and a second spool 50. As in the devices already described, the fabric 12 is fully loaded in the first reel 48. Then the fabric passes under the hydro-jets. Three separate jets 52, 54, and 56 are shown in Figure 4 and should be considered as an example. As in the arrangements of Figures 1-3, the embodiment of Figure 4 may include a single jet and a pair of jets. A hydrometer measuring unit 58 is illustrated as interposed between the final jet 56 and the second reel 50. The degree of hydrometer imparted to the fabric 12 is thus measured as the fabric is wound onto the second reel 50. Once the fabric 12 it has been completely wound on the second reel 50, the process is reversed and the fabric is completely rerolled on the first reel 48. The reciprocal process will continue until the desired degree of hydroreapering is reached. It should be understood that further processing, such as the one illustrated in figure 3 can also be incorporated in the reciprocal system illustrated in figure 4. As mentioned, the use of a minimum number of jets in a reciprocal system allows great flexibility in the hydrometer process. Figure 5 illustrates another embodiment of the reciprocal system of the invention. This arrangement uses vacuum rollers and includes three separate hydrometer jets. As with the other embodiments, the fabric 12 is first loaded on the first reel 60. Subsequently the fabric 12 is passed through a pair of tension adjusters 62 and 64 and subsequently passes over a first roller 66. a first hydrometer jet 68 is placed to provide a front hydrometer treatment to the fabric 12, as indicated by the letter F in Figure 5. Subsequently the fabric 12 passes over a second vacuum roll 70, wherein a second hydro-jet stream 72 is used. to perform a back treatment of the fabric 12 (indicated by B in Figure 5). Finally the fabric 12 passes through a third vacuum roller 74, where it passes through a second pair of tension adjusters 78 and subsequently enters a humidity measurement unit 80. The fabric 12 is taken on a second spool 82, (must it is understood that a permanent or semi-permanent guide may be used to join the fabric 12 between the first reel 60 and the second reel 82). According to the teachings of the invention, once it has been fully loaded on the second reel 82, the process is reversed and the fabric is subjected to a hydrometer in the opposite direction, as indicated by the dotted lines, until the fabric has been fully reloaded in the first reel 60. Any number of forward and backward steps required to impart the desired degree of hydrometer can be made. The ability to control the three separate jets 68, 72, 76 in combination is the control of the number of forward and backward steps resulting in a very flexible system. For example, the arrangement of Figure 5 could be controlled so that the first jet and the second jet 72 are used in a forward direction (front / rear treatment) with the third jet 76 and the second jet 72 used in the direction of Reverse (front / back treatment, thus providing the most effective side-by-side improvement). Alternatively, the jets 68 and 76 could be used in the forward direction (two front treatments for single-sided improvement) or only the jet 72 used (treatment only on the rear side). Various other modifications and alternatives may be thought and considered to fall within the scope of the present invention, for example, although the above discussion has been directed to the hydrometer process, the same reciprocal technique can be used in certain processes of "hydrorevoltage or -coupling" with non-woven material.

In particular, the nonwoven materials that have been reinforced (for example with a needle) can have sufficient integrity to allow a reciprocal hydro-coupling system.
