Description

Method of manufacturing for light-insulating wrinkled fabrics {Method of manufacturing for Wrinkled, light and warm fiber fabrics}

The present invention relates to a method for manufacturing a lightweight insulating wrinkle fabric.

In order to form wrinkles on the fabric, a method of pushing the fabric into a bag provided with a certain shape and fixing the wrinkles with high-temperature steam or hot water was done manually, but the fabric was not evenly formed with wrinkles.

In addition, the shape of the wrinkles is simple, wrinkles are easily spread, mass production by hand is not possible, there is a problem that the product cost increases during production.

Accordingly, recently, an apparatus for forming wrinkles using a forming roller and a blade is used.

For example, after forming the wrinkles by the reciprocating motion of the blade on the supplied fabric, and passing the fabric between the forming rollers equipped with a heating device, the fabric is pressurized and heated to form a wrinkle pattern repeatedly.

However, this prior art is a method of forming a wrinkle by pressing and heating the entire surface of the fabric, and the fabric fabric used is limited to a high concentration of polyester fabric fabric.

In the case of polyester, it has excellent thermal stability and dyeability, and has a soft touch, and is widely applied to clothing materials. However, it is difficult to use as a clothing material for autumn and winter when the weather is cold due to lack of light weight and heat retention.

In addition, the prior art is a method in which the fabric fabric is gathered in the form of wrinkles and then depressurized by heating through a molding roller, whereby not only the portion where the wrinkles are caught, but also the entire fabric fabric to be injected is affected by deterioration.

In addition, for this reason, limitations occur in the temperature and time of heat that can be applied to the fabric. Therefore, it is not only possible to use a fabric fabric made of a thick material having excellent heat retention properties, but there is a problem in that wrinkles are easily released even when the wrinkles are molded by using them.

Hereinafter, preferred embodiments of the present invention designed to solve the above problems will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a cross-section of a core sheath composite fiber in a method for manufacturing a lightweight insulating pleated fabric according to an embodiment of the present invention, and FIG. 2 is a process flow diagram showing a method for manufacturing a lightweight insulating pleated fabric according to an embodiment of the present invention .

1 and 2, the method for manufacturing a lightweight insulating pleated fabric according to an embodiment of the present invention is an input step (S100), a fixing step (S105), a pressing step (S110a, S110b, S115a, S115b) and a molding step (S120a, S120b).

In more detail, by inserting and fixing the fabric fabric 100 having light weight insulation to the wrinkle fabric manufacturing apparatus, and pressing and heating to form the wrinkles, a wrinkle fabric having light weight insulation is manufactured.

In one embodiment of the present invention, the fabric fabric 100 may be a core sheath composite fiber 110.

The composite fiber is a composite yarn made of chemical fibers having a special structure and properties, and is made by extruding polymer materials having two different components from the same spinneret. The core sheath composite fiber 110 is a core component and fibers constituting the inside of the fiber. It is a composite fiber composed of super fiber constituting the outside of the material using different fiber materials.

The fiber cross-section of the core sheath composite fiber 110 may be made of a core component judging 111 and a super component core yarn 113 as illustrated in FIG. 1. That is, as shown in (a), it may be composed of a screening section 111 and a yarn 113 having a circular cross section, and as shown in (b), a screening section 111 formed of a plurality of circular sections and a screening section 113 with a single circular section may be formed. It may be made, and (c) may be made of a deformed star-shaped cross-section 111 and a circular cross-section 113.

The core sheath composite fiber 110 according to an embodiment of the present invention may be manufactured by composite spinning of 30 to 70% by weight of the core component containing polyolefin and 70 to 30% by weight of the super component containing polyester.

The core component is composed of a polyolefin and a compatibilizer, and the super component may be polyester.

The polyolefin can be polyethylene or polypropylene.

The polyolefin may be at least one homopolymer selected from the group consisting of polyethylene, polypropylene and polybutene having a melting point of 100 ° C or higher, or a copolymer thereof, and polypropylene is particularly preferred in terms of fiber molding.

The polypropylene component is a homopolypropylene having a linear structure of 90 to 99% isotetic, and the melt flow rate (hereinafter “MF”) may be about 15 to 40 g / 10 minutes according to ASTM D-1238 (L). When the MF value is high, the viscosity of the core portion is lowered, which makes it difficult to form an interface with the polyester resin of the super component, and shows an eccentric structure that is tilted to one side. When the MF value is 15 g / 10 min or less, trimming occurs during spinning due to a decrease in flowability of the core component. It can cause process failure.

The compatibilizer may occupy 0.1 to 3% by weight in the core component. The compatibilizer is preferably a polyolefin in which 2 to 10% by weight of maleic anhydride is grafted with respect to the total use agent. A polyolefin-based compatibilizer with maleic anhydride grafted may be used to prevent separation of the interface of the core-sheath type cross-section.

More specifically, the maleic anhydride-grafted polyolefin-based compatibilizing agent may be a resin (hereinafter referred to as 'MA-PP' or 'MA-PE') in which maleic anhydride is grafted to polypropylene or polyethylene at a level of 2 to 10% by weight. have.

At this time, maleic anhydride cross-links the carboxyl group of the polyester, which is a super component, and serves to prevent separation or separation of the core component and the super component from external forces in a later process. The long fiber composite material has a problem in that the amount of dyeing occurs because the polyolefin as a core component is not dyed when the interface is separated. However, a maleic anhydride (MA) grafted polyolefin-based compatibilizer is used as a core component to form a crosslink between the super component and the core component, thereby preventing separation and separation of the core component and the super component in a subsequent process. have.

The polyester resin used in the super component means all aromatic polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate, or aliphatic polyesters such as polylactide.

When producing the core sheath composite fiber 110, the temperature of the polymer line and the spinning temperature of the super component and the core component should be adjusted according to the relative viscosity and the MF value of the super component and the core component. Generally, 265 ~ 295 ℃ is suitable for polyester, and 250 ~ 285 ℃ is suitable for polypropylene as a core component. However, when the polymer viscosity of the super component and the core component are different from each other, the complex cross-section formation of the super component and the core component becomes non-uniform, and thread trimming is likely to occur during spinning. Therefore, in order to control the melting viscosity of the super component and the core component in proportion to the spinning temperature, it is desirable to maintain the melt viscosity of the super component slightly lower than the core component.

As described above, when the fabric fabric 100 is manufactured using a core sheath composite fiber 110 composed of a polyolefin core component and a polyester super component, a wrinkle fabric having a soft feel while having light weight and heat retention is manufactured. can do.

In more detail, since the fabric fabric 100 used in the production of the pleated fabric must be molded through thermal processing, there is a limit in material selection to use the polyester fabric fabric 100 having excellent thermal safety. However, since the polyester fabric fabric 100 is weak in heat retention and light weight, wrinkled clothes using the polyester fabric fabric 100 are difficult to wear in the winter, and also the insulation of the polyester fabric fabric 100 is maintained. To increase the thickness of the polyester fabric fabric 100 in order to improve, there is a problem in that the produced wrinkled clothes become heavy and difficult to wear.

In addition, when the polyolefin has a low specific gravity and a low thermal conductivity, it can be used as a yarn for clothing to obtain a product with excellent light weight and heat retention. However, there is a problem in that it is difficult to use for clothing because it is not dyed and has low thermal safety.

Therefore, when polyolefin is used as the core component and the core sheath composite fiber 110 using polyester as the super component is used, it is possible to manufacture a wrinkle fabric having excellent light weight and heat retention compared to a wrinkle fabric previously used only for polyester. .

In other words, by using polyester, which has excellent thermal stability and dyeability, and expresses with a soft touch, as a super component, it is possible to manufacture a wrinkled fabric due to the super component of polyester, while producing a wrinkled fabric conventionally due to the core component of polyolefin. Compared to the polyester fabric fabric (100) used in the has the advantage of being able to produce a wrinkled fabric excellent in light weight and heat retention.

The core sheath composite fiber 110 may be made of a structure of the screening 111 and the screening 113 to be thick. When the thickness of the fabric fabric 100 is thick, there is difficulty in forming wrinkles. This difficulty can be solved by using the method for manufacturing a wrinkled fabric according to an embodiment of the present invention.

According to an embodiment of the present invention, an apparatus for manufacturing a pleated fabric may include an operation command input unit, a controller, a fabric fabric supply unit, a fabric fabric molding unit, and a fabric fabric discharge unit.

The operation command input unit consists of a power on / off button, a work start button, a setting value change button, etc., and outputs an operation command signal to the controller according to the operator's button operation. When the operation command input unit is composed of a touch screen capable of inputting and outputting, it provides a plurality of menus to receive the operation command, and the operator can select a desired menu among a plurality of menus and input a desired command value.

The controller receives the operation command input through the operation command input unit and controls the fabric fabric supply unit, the fabric fabric molding unit, and the fabric fabric discharge unit, so that the fabric fabric 100 is formed with wrinkles.

After the fabric fabric supply unit is placed on the supply end for the wrinkle forming operation, when the fabric fabric supply command is input from the controller, the fabric fabric 100 placed on the supply end is transferred at a predetermined speed to the upper portion of the fabric fabric forming part. To be inserted between the jig 300 and the lower jig 500.

In this way, in the fabric fabric forming part, when the fabric fabric 100 is placed between the upper jig 300 and the lower jig 500, the upper jig 300 and the lower jig 500 are coupled to each other, and the upper jig 300 ) Presses the fabric fabric 100 by the upper projection 310 formed on the lower projection 510 formed on the lower jig 500 and fixes the fabric fabric 100. At this time, the upper protrusion 310 and the lower protrusion 510 may be formed to correspond to each other so as to be engaged with each other and combined.

The fabric fabric 100 is fixed in the form of a wrinkle by the upper protrusion 310 and the bottom protrusion 510 which are engaged and combined to maintain the wrinkle shape.

Next, the end of the upper projection 310 and the end of the lower projection 510 presses one surface of one end of the fabric fabric 100. And, the upper heating layer 700 and the lower heating layer 800 is pressed on the other surface of one end of the pressurized fabric fabric 100 corresponding to one surface of one end of the pressurized fabric fabric 100, the fabric fabric 100 In the pressurized state, wrinkles are fixed by the heat of each heating layer.

In more detail, the end of the upper projection 310 presses one surface of one end of the fabric fabric 100, and the lower heating layer 800 presses and heats the other surface of one end of the fabric fabric 100 corresponding thereto. The end of the lower projection 510 presses one surface of one end of the fabric fabric 100, and the upper heating layer 700 presses and heats the other surface of one end of the fabric fabric 100.

After the fabric fabric discharge portion is wrinkled on the fabric fabric 100, it is transferred at a preset speed between each jig to be separated, so that the wrinkle fabric having the wrinkle formed is discharged.

Below is a detailed description of each step of manufacturing the wrinkled fabric is configured as described above.

The input step (S100) is to insert between the upper jig 300 and the lower jig 500 to fix the fabric fabric 100 to form a wrinkle.

In more detail, the upper jig 300 and the lower jig 500 are formed to correspond to each other and are separated from each other, and when the fabric fabric 100 is inserted between the upper jig 300 and the lower jig 500, the upper jig 300 ) And the lower jig 500 are combined.

The fixing step (S105) is to fix the fabric fabric 100 in order to form wrinkles on the fabric fabric 100 inserted between the upper jig 300 and the lower jig 500.

In more detail, the upper jig 300 has a plurality of upper protrusions 310 formed at regular intervals in the direction of the lower jig 500, and the lower jig 500 has a plurality of lower protrusions 510 in the direction of the upper jig 300 ) Is formed at regular intervals. The upper protrusion 310 and the lower protrusion 510 are preferably formed in a serrated shape.

The upper projection 310 and the lower projection 510 are arranged to be staggered with each other, and each projection and recess are correspondingly engaged and engaged to each other at a certain depth, so that the fabric fabric 100 to be fixed is folded in the form of horizontal or vertical wrinkles. It can be fixed.

That is, since the upper projection 310 and the lower projection 510 are engaged with each other and coupled, the fabric fabric 100 fixed between the ends may exhibit a wrinkled shape.

The pressing step (S110a, S110b, S115a, S115b) is a lower heating layer located below the upper projection 310 and the lower end of the upper projection 310 formed below the upper jig 300 through the fixing step (S105). One end of the (800) is pressed against each of the corresponding both surfaces of the one end of the fabric fabric 100, and is located on the upper end of the lower projection 510 and the lower projection 510 formed above the lower jig 500. That is, one end of the upper heating layer 700 is pressed against each of the corresponding both surfaces of one end of the fabric fabric 100.

In more detail, the lower end of the upper projection 310 and the upper surface of the lower heating layer 800 are placed with one end of the fabric fabric 100 interposed therebetween, and pressure is applied to the fabric fabric 100 from both sides, and the lower projection ( The upper end of 510) and the lower surface of the upper heating layer 700 are placed with one end of the fabric fabric 100 interposed therebetween, and the fabric fabric 100 is pressurized from both sides.

The forming step (S120a, S120b) is to form a wrinkle on one end of the fabric fabric 100 in contact with each heating layer, while heating each heating layer.

In more detail, the heating layer may be formed by heating one end of the fabric fabric 100 in contact with each other at about 140 degrees for 1 minute. However, the present invention is not limited thereto, and it is obvious that the temperature and time applied to the fabric fabric 100 for wrinkle forming may vary depending on the composition and thickness of the fabric fabric 100.

In addition, in forming the wrinkles, the method of manufacturing a wrinkled fabric according to an embodiment of the present invention pressurizes and heats only one end of the fabric fabric 100, so that it is concerned with the overall deterioration of the fabric fabric 100 and is sufficiently pressurized for wrinkle formation and Unlike the case where the heating was not possible, since only one end of the fabric fabric 100 is deteriorated, it is possible to pressurize and heat the fabric fabric 100 with sufficient time.

In addition, after the forming steps (S120a, S120b), when the wrinkles are molded on the fabric fabric 100 may include a release step (S125) that the upper projection 310 and the lower projection 510 are separated from each other.

In addition, after the release step (S125), a discharge step (S130) for discharging and discharging the fabric fabric 100 formed by wrinkles between the separated upper jig 300 and the lower jig 500 at a predetermined speed is discharged. It may further include.

According to the present invention of the above configuration, it is possible to manufacture a wrinkled fabric having wrinkles while reducing the thermal damage of the fabric fabric 100 to a minimum.

That is, by heating only one end of the fabric fabric on which the wrinkles are molded to form the wrinkles, a wrinkle fabric having an original texture of the fabric fabric can be produced at other portions except for the region on which the wrinkles are molded.

In more detail, in the prior art, in the method of manufacturing the pleated fabric with the fabric fabric 100, the pleats were molded using a blade device while the fabric fabric 100 was inserted between the rotating upper roller and the lower roller.

At this time, since the front surface of the fabric fabric 100 for forming the wrinkles is heated, the fabric fabric 100 is deteriorated when high temperature and long time heat is applied to the fabric fabric 100 to mold the wrinkles so that the wrinkles are not easily released. There was a problem that the soft texture of the produced wrinkled fabric disappeared. In addition, in the case of molding at a temperature and time insufficient to mold the wrinkles in order to maintain the original texture of the produced wrinkled fabric, the original texture is maintained, but the wrinkles are not well molded or the generated wrinkles are easily released. there was.

According to the present invention of the above configuration, by using each projection formed orthogonal to each jig, there is an advantage that can form the wrinkles in a state erected on the fabric fabric (100). The pleated fabric with erected wrinkles has the advantage of superior aesthetics compared to the pleated fabric with folds formed.

In more detail, the conventional method of manufacturing a pleated fabric with the fabric fabric 100 has a problem in that the pleated fabric is inevitably produced by manufacturing the pleated fabric through a rotating upper roller and a lower roller.

According to the present invention of the above configuration, it is possible to reduce the time and effort required to hold the erected wrinkles.

In more detail, in the related art, in order to manufacture a pleated fabric erected with a fabric fabric 100, after cutting a wrinkle shape in a separate paper fabric, a person manually folds the fabric fabric and fabric fabric 100 and puts it in the oven and steams it. Use This is a manual process, so it has a problem that it takes a long time.

Figure 3 is a schematic cross-sectional view showing a state in which the fabric fabric 100 is fixed to a jig in the method of manufacturing a lightweight insulating wrinkle fabric according to an embodiment of the present invention, Figure 4 is a lightweight insulating wrinkle according to an embodiment of the present invention It is a schematic perspective view showing the lower jig 500 in the fabric manufacturing method.

Since the upper jig 300 is also formed to correspond to the lower jig 500, the upper jig 300 will be described with reference to FIG. 4.

 3 and 4, the upper jig 300 is opened to correspond to the lower protrusion 510 so that the lower protrusion 510 penetrates and a part of its end protrudes upward from the upper jig 300. It includes an upper perforation 330, the lower jig 500 is opened to correspond to the upper projection 310 so that the upper projection 310 penetrates and a part of its end may protrude downward of the lower jig 500 A lower perforation 530 may be included.

The end of each projection protrudes outward of the perforation opened to a predetermined height, and the protruding height at this time may be a height that can be covered by the elastic layer of each heating layer.

In this case, one end of the fabric fabric 100 that is pressed by the lower protrusion 510 and protrudes to the upper side of the upper jig 300 is in contact with the upper heating layer 700 formed on the upper side of the upper jig 300 and wrinkles while being heated While being formed, and pressed by the upper protrusion 310, one end of the fabric fabric 100 protruding to the lower side of the lower jig 500 is heated while contacting the lower heating layer 800 formed on the lower side of the lower jig 500 Wrinkles can be molded.

According to this, it is limited to one end of the fabric fabric 100 protruded by each perforation, so that wrinkles forming by heat proceeds, and heat is not transmitted to the fabric fabric 100 that does not protrude, thereby forming a wrinkle on the fabric fabric 100 When the wrinkle lines are formed, deterioration can be prevented in other areas.

The heating layer is to form a wrinkle by applying heat to one end of the fabric fabric 100, and the lower heating formed on the lower side of the upper heating layer 700 and the lower jig 500 formed on the upper side of the upper jig 300. Layer 800 may be included.

The upper heating layer 700 may be separated or combined with the upper jig 300, and may include a heat resistant upper elastic layer 710 on the lower surface.

The upper elastic layer 710 may contact the one end of the fabric fabric 100 protruded by the lower protrusion 510 and transfer heat of the upper heating layer 700 to one end of the fabric fabric 100.

The upper elastic layer 710 may be formed of an elastic material capable of wrapping and pressing one end of the fabric fabric 100 protruding while being heat resistant.

The lower heating layer 800 may be separated or combined with the lower jig 500, and may include a heat resistant lower elastic layer 810 on the upper surface.

The lower elastic layer 810 may be in contact with one end of the fabric fabric 100 protruded by the upper protrusion 310 to transfer heat of the lower heating layer 800 to one end of the fabric fabric 100.

The lower heating layer 800 may be formed of an elastic material that can wrap around and press one end of the fabric fabric 100 protruding while being heat resistant.

Figure 5 is an enlarged view of the main portion of the lower projection in the method for manufacturing a lightweight insulating wrinkle fabric according to an embodiment of the present invention.

Since the upper projection 310 is also formed to correspond to the lower projection 510, the upper projection 310 will be described together with reference to FIG. 5.

3 to 5, the upper projection 310 includes an upper jetting port (not shown) capable of jetting a printing material at the lower end facing the lower heating layer 800, and the lower projection 510 is The upper heating layer 700 may include a lower jetting port 511 capable of jetting a printing material at an upper end facing the upper heating layer 700.

The ejection opening formed in each projection can be supplied with a printing material from the inside of each projection, so that a predetermined amount can be ejected to be cut on one surface of one end of the fabric fabric 100 facing the end of each projection. At this time, the amount ejected can be controlled by an operation command input unit or a controller.

The printing agent is a printing agent for forming wrinkles containing a water-soluble resin and a blowing agent.

Wrinkle-forming printing material containing a water-soluble resin and a foaming agent, after the printing material is printed on the fabric fabric 100 through each spout, and heated by each heating layer, forming a wrinkle including the water-soluble resin and the foaming agent The foaming agent contained in the molten printing material is foamed to form wrinkles on the fabric fabric 100.

That is, wrinkles are formed once on the fabric fabric by each protrusion and each heating layer, and wrinkles are further molded by a printing material for forming wrinkles including a water-soluble resin and a foaming agent.

This has the effect of forming wrinkles on the thick fabric fabric 100, which is not well formed with wrinkles, as well as the general fabric fabric.

This has the effect of forming wrinkles that are not easily spread even on the thick fabric fabric 100 made of the core sheath composite fiber 110.

In addition, the conventional wrinkle forming method has a problem in that wrinkles easily spread over time. On the other hand, the wrinkles formed by the printing material for forming wrinkles containing a water-soluble resin and a foaming agent have an advantage that shape change does not occur even after washing.

The spraying of the printing material for forming wrinkles containing a water-soluble resin and a foaming agent on the contact surface of the fabric fabric 100 (S117a, S117b) is a pressing step in which each projection and each heating layer are in contact with the fabric fabric 100 therebetween. It is preferable to perform (S115a, S115b, S117a, S117b). In this case, in the state where each protrusion and each heating layer hold the pleated shape of the fabric fabric 100, it can be made to be cut only in a predetermined area when each spout comes into contact.

In the case of forming wrinkles using a printing material for forming wrinkles containing a water-soluble resin and a foaming agent, it is preferable to apply the wrinkles by foaming at a temperature of 100 to 200 ° C. This temperature prevents the shrinkage of the fabric and makes the wrinkles free and the washing process easy with the expanded part swollen during high-temperature foaming.

6 is a process flow diagram illustrating some additional processes in the method for manufacturing a lightweight insulating pleated fabric according to an embodiment of the present invention.

Referring to FIG. 6, the printing material for wrinkles including water-soluble resin and foaming agent that has been blown out and sealed on the contact surface of the fabric fabric 100 may be foamed by heat of the heating layer in the forming step (S120a-1, S120a-2).

In more detail, the fabric fabric 100 is fixed in a corrugated shape through the process of engaging and engaging each projection, and under one fixed condition, one surface and the other surface of one end of the fabric fabric 100 by each projection and each heating layer. It is pressurized.

Thereafter, a printing material for forming wrinkles containing a water-soluble resin and a foaming agent is ejected on one surface of one end of the fabric fabric 100 pressurized by the respective projections and printed.

Thereafter, heat applied to each heating layer contacting the other surface of one end of the fabric fabric 100 to which the printing material for wrinkle formation including the water-soluble resin and the foaming agent is sealed is transferred.

At this time, when the heat reaches a certain temperature or more, the foaming agent contained in the printing material for forming wrinkles containing a water-soluble resin and a foaming agent foams and can form wrinkles.

After the molding step (S120a-1, S120a-2) in which the wrinkles are molded on the fabric fabric 100 by a printing material for forming wrinkles containing a water-soluble resin and a foaming agent, the fabric fabric 100 with wrinkles is washed with water It may include a washing step (S135) for removing the printing material for wrinkles containing water-soluble resin and blowing agent.

In more detail, the washing step (S135) is to remove the printing material for wrinkle formation including the water-soluble resin and the foaming agent remaining in the water washing process of the wrinkled wrinkled fabric.
