Description

METHOD FOR PRODUCING DOUBLE SHRINK FABRIC AND ITSELF BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a method of manufacturing a double shrink fabric and an invention relating to the fabric by the manufacturing method, and more particularly, to a method of manufacturing a fabric composed of a surface fabric, a back fabric and a cushion layer, A plurality of warp yarns made of warp yarns are placed in a weaving machine and the surface fabric, the cushion layer and the back fabric are simultaneously weighed and knitted to produce a double shrink fabric having a contraction portion and a raised portion on the surface of the fabric .

A general fabric which is woven by crossing a warp and a weft forms a two-dimensional flat shape, so that a plurality of layers of the same kind or different kinds of fabrics are laminated so as to impart functionality such as cold or warmth through volume feeling or volume feeling Have been developed and provided.

A representative example of multi-layered fabrics is a fabric which is made by sewing cotton or wool between two layers of fabric with an embedding material and sewing it with an outer embroidering material to fix them. Because of the voluminous feeling due to the bulkiness of my charm, it is used for various purposes by imparting soft touch as well as warmth.

On the other hand, a method of fabricating various fabrics for improving the feel by providing a unique texture to the surface of the fabric is provided in a manner different from the method of imparting a sense of volume through the multi-layered fabric as described above.

The most typical example is calendering. The surface of the fabric is smooth and polished by using a roller type calendar, or the embossing calender is used to form texture on the surface of the fabric.

Various processing methods such as forming a wrinkle pattern on the surface of a fabric using a chemical such as resin, acid, or alkali, or imparting a crepe effect have been carried out in addition to a physical method such as calendar processing and brushed processing.

In addition, in recent years, a method of imparting texture to the surface of a fabric using heat shrinkability of fibers has been provided. For example, a configuration of a technique known in Patent Publication No. 10-0389283 will be briefly described below.

The fabric is sewn in a longitudinal direction or a transverse direction by using a heat-shrinkable and water-soluble sewing thread, and the stitched garment is heat-treated at 140 to 170 DEG C for about 1 to 3 minutes, The shrinkage wrinkles are formed in the longitudinal direction or the transverse direction by causing the shrink wrinkles to be contracted so that the garment having the shrink wrinkles is put into the wrinkle forming machine to form straight wrinkles in the direction intersecting the shrink wrinkles, So that natural shrinkage wrinkles and simple straight wrinkles are formed on the garment and the fabric.

As another example, in the case of forming a wrinkled molded fabric on the surface, such as the technique disclosed in Registration Practical Utility Model No. 20-0337190, in the case where the shrinkage rate is 3 to 8% A plurality of stitched stitches are exposed by the stitched area, and wrinkled stitches are formed on the stitched area of the stitched fabric by the woven fabric that is shrunk when the stitched fabric is thermally treated and pressed. .

As another example, there is a first step of inserting a shrinkable fabric to be shrunk by heat treatment between a cloth and a lining so as to overlap with each other, as in the technique disclosed in Patent Document 10 - 2001 - 0083507, A second step of performing a quilting operation in which the fabric is folded in one direction or both in the vertical and horizontal directions by using a quilting machine or a sewing machine; and a second step of heating the fabric to a predetermined temperature after completion of quilting in the second step, And a third step of shaping the fabric so that the fabric is contracted and the outer cloth is swollen to a predetermined width.

Registration No. 10 - 0389283 (Jun. 25, 2003) Registration Utility Model No. 20-0337190 (2004.01.03) Published Patent No. 10 - 2001 - 0083507 (September 1, 2001) Registration No. 10 - 0974443 (Aug. 6, 2010)

According to the above-described conventional method for manufacturing a pleated garment and a fabric, a heat-shrinkable sewing thread is used to stitch the garment into a garment, followed by heat treatment to form a corrugation, and after the corrugation is formed, the sewing thread is dissolved and removed.

Therefore, in the prior art, since the wrinkles are formed on the fabric along the lines stitched by the saddle-stitching yarns, it takes a considerable amount of time and effort only for the process of stitching when the woven fabric is formed over the entire fabric. It is also accompanied by a considerable difficulty.

On the other hand, another prior art wrinkle fabric processing fabric is constructed to superimpose a skin support portion having no shrinkage ratio and a backing support portion having a shrinkage ratio, and then forming a wrinkle on the skin by a shrinkage caused by heat treatment.

Another method of manufacturing a quilted fabric using a conventional shrinkable fabric is as follows: a process of weaving outer materials and lining, inserting shrinkable fabrics therebetween, overlapping them, quenching them, and then heat- .

Therefore, in the conventional techniques, since the process of weaving each fabric, the process of superimposing and laminating them, and the process of heat treatment are separately performed, the professional manpower and the device according to the execution of the corresponding process must be separately provided There is a problem in that the manufacturing process is inefficient such that the time required for the process is increased and the economic burden is caused thereby.

In addition, when the multi-layered fabric is laminated and stacked as described above, the individual fabric is pushed or stretched along the sewing line, or the fabric is deformed by the heat treatment, so that the stranded wire is often deformed or cut. It is difficult to properly form the desired wrinkles even after the subsequent heat treatment, thereby lowering the quality of the finished fabric.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art,

(S10) of sewing a surface fabric by crossing a plurality of surface warps with surface weft yarns, a back weaving process (S20) of weaving a plurality of back warp yarns crossing the back weft yarns, And a cushion layer forming step (S30) for forming a cushion layer by putting a cushion weft between the fabrics is performed simultaneously, the method comprising:

The front surface and back surface inclination are adjusted so as to alternate with the same inclined beam in the weft direction by a predetermined number of strands using a low shrinkage warp and a high warp yarn,

The surface weaving process (S10) and the back weaving process (S20)

(S11, S21) of forming a contraction portion by surface and back side warp yarns with a front and back weft yarns constituting a corrugated fiberboard stock, and a surface and back side warp yarns composed of a low contraction yarn are woven with front and back weft yarns to form a raised portion (S12, S22);

In the surface weaving process or the cushion layer forming process (S10 to S30), the front surface and back surface inclination are crossed with each other at intervals of a predetermined number of stitches so that the surface cloth, the cushion layer, and;

The fabric having been subjected to the surface weaving process or the final process (S10 to S40) is subjected to a finishing process (S50), wherein the shrinkage of the length L of the unit warp relative to the ridge is shorter than that of the ridge, It is possible to easily produce a double shrink fabric having a contraction portion and a protrusion portion.

The present invention has the advantage of making it easier to produce dual shrinkage fabrics having a shrink portion and a bulge portion in the surface fabric and the back fabric in the production of the fabric comprising the surface fabric, the cushion layer and the back fabric.

That is, a plurality of surface and back surface warp yarns constituted by a stiff core yarn and a low-shrink yarn are positively wound on the same oblique beam so as to be overlaid on the weaving machine, and the weaving and binding results of the surface fabric, the cushion layer, Can be greatly shortened and productivity can be improved accordingly.

Particularly, as compared with a conventional method in which a separate thread is stitched on a fabric or a multi-ply fabric having different shrinkage ratios is stitched and heat treated, the present invention relates to a method for fabricating a surface fabric and a backing fabric, There is an advantage that the surface texture (wrinkle, volume feeling) of a desired bar can be derived more naturally and evenly semi-permanently by using the warp yarns formed.

The method of manufacturing a double shrink fabric according to the present invention and the fabrics according to the fabrication method of the present invention can be applied to the fabrics of the surface fabric 110, the back fabric 120 and the cushion layer 130, It is noted that the present invention relates to a technique for easily manufacturing a double shrinkage fabric formed by alternately arranging the contraction portion 140 and the protrusion portion 150 on the surface of a fabric using a plurality of surfaces made of contraction yarns and a back surface inclination 111 and 121.

As shown in FIG. 1, the method for fabricating a double shrink fabric according to the present invention includes a surface weaving process S10, a back weaving process S20, a cushion layer forming process S30, Are concurrently carried out. Concretely, it is as follows.

The duplex shrinkage fabric of the present invention is a multiple fabric having a cushion layer 130 formed between a surface fabric 110 and a backing fabric 120 so that the surface fabric 110 and the backing fabric 120 have the same tissue structure .

The surface weaving process S10 wraps the surface fabric 110 by crossing the surface weft yarns 112 up and down in a plurality of surface warps 111. [

In the back side weaving process S20, the back side fabric 120 is woven by intersecting the back side wefts 122 in a vertical alternating manner.

As shown schematically in FIG. 2, the plurality of surface and back surface warp threads 111 and 121 used for the surface fabric 110 and the back surface fabric 120 are made to be the same oblique beam, In the weft direction, and the weft yarn is transferred to the weaving machine.

Generally, the high-stiffness fiber is a heat-shrinkable fiber having an average shrinkage ratio of 7 to 8%, which is the average shrinkage percentage of the synthetic fiber. The fibers are stretched after sizing after sizing the fibers to have properties such as bulging property, tensile strength, and change in physical properties due to heat, thereby exhibiting stretching properties of the fiber structure by heat treatment. The manufacture and characteristics of the cornucopia are well known in the art, so a detailed description thereof will be omitted.

That is, the front and back warp yarns 111 and 121 are alternately arranged on the same oblique beam so as to cross the front and back weft yarns 112 and 122 to weave the front and back weft yarns 110 and 120, After completion of the post-processing step (S50) to be described later, the difference in shrinkage ratio between the tortuous sloping slopes 111a and 121a and the sloping slopes 111b and 121b included in the tissue regions of the surface fabric 110 and the backing fabric 120 Thereby forming different surface textures in each region.

The surface weaving process S10 includes a shrinking process S11 in which a plurality of surface warp yarns 111a made of hard core stock are woven with a surface weft yarn 112 to form a shrinkage portion 140, (S11) in which the surface warp threads 111b of the warp threads 111 are woven with the surface weft yarns 112 to form the protruding portions 150. The surface weft yarns 110 are woven.

Therefore, after the shrinking portion 140 and the protruding portion 150 formed on the surface fabric 110 as described above are subjected to the post-processing step S50 to be described later, the contraction portion 140 is taut And a feeling of volume is formed in the protrusion 150 relatively.

Similarly, the back side weaving process S20 is performed simultaneously with the surface weaving process S10, and the back side weft yarn 121a, which is made up of a high number of stock yarns, is woven with the back side weft yarn 122 to form the contraction portion 140 And a raising and lowering step S21 in which a plurality of back side warp yarns 121b made of a low shrinkage yarn are woven with the back side weft yarns 122 to form a raised portion 150, do.

3, the shrinkage portion 140 and the ridge portion 150 formed on the back fabric 120 may have different shrinkage ratios due to different shrinkage ratios between the fibers after the post- The portion 140 is stretched tightly and relatively to the raised portion 150 to form a sense of volume.

In the present invention, the above-mentioned high-strength stock yarns used for the front and back warp yarns 111 and 121 are synthetic fibers having a fineness of 90 denier and a shrinkage ratio of 12 to 18%, and the low shrinkage yarn is a synthetic fiber having a fineness of 75 denier and a shrinkage ratio of 3% And polyester yarn is preferable. The difference in the fineness and the shrinkage rate between the shelf and the shelf is determined by the shape of the contraction portion 140 and the protrusion 150 formed on the surface of the fabric and the quality of the finished fabric, Do.

At the same time as the surface fabric 110 and the back fabric 120 are woven by the surface weaving process S10 and the back weaving process S20, the cushion layer forming process S30 is performed, The cushioning weft yarn 131 is placed between the backing fabric 110 and the backing fabric 120 to form the cushioning layer 130.

The cushion weft yarn 131 may be made of a heat-shrinkable core, a water-holding core, a water-holding core, and the like. In order to sufficiently fill a space between the surface fabric and the back fabric, It is preferable that it is composed of synthetic fibers having a denier of 300 to 450 denier.

Accordingly, as a minute loop is developed in the cushion weft yarn 131 by the heat treatment through the post-processing step (S50) to be described later, the void is formed as if it is through the pitch skin processing or the loop processing, The cushion layer 130 is formed.

In addition, the cushion weft yarn 131 is provided in a non-woven state by using a separate inclination, so that the volume feeling of the contraction yarn is doubled to increase the thermal effect and the aesthetics due to the cushion layer 130.

In the surface weaving process or the cushion layer forming process S10 to S30, the front surface fabric 110, the cushion layer 130, and the back surface fabric 120 (S40) are concurrently carried out.

That is, as shown in the cross-sectional view of FIG. 5, one of the plurality of surface warp yarns 111 that weave the surface cloth 110 crosses the surface weft yarn 112 instead of crossing the surface weft yarn 112 One of the plurality of back side warp yarns 121 crossing the back side weft yarns 120 intersects with the surface weft yarns 112 instead of intersecting the back side weft yarns 122 so that the three- .

Thus, in the prior art, it is possible to exclude processes such as laminating fabrics already woven in the manufacture of fabrics made up of multiple-ply fabrics, and then joining them with pile fabrics.

As shown in comparison with FIGS. 5 (a) and 5 (b), the raw fabric having passed through the surface weaving process or the final process (S10 to S40) is subjected to heat treatment through a post-process (S50) The shrinkage portion 140 whose length L is shorter than that of the ridge portion 150 is formed so as to alternate with the ridge portion 150 in the weft direction, Shrink fabric.

As shown in FIGS. 3 to 4, the raw fabric according to the method of manufacturing a double shrink fabric according to the present invention having the above-described structure is formed by crossing a plurality of surface warp yarns 111 with a surface weft yarn 112 A backing fabric 120 that is woven to cross the backing weft yarns 122 with a plurality of backing warp threads 121 and a cushion weft yarn 131 between the front and back fabrics 110 and 120. [ And a cushion layer 130 which is formed by overtopping the cushion layer 130.

That is, the surface fabric 110, the cushion layer 130, and the backing fabrics 110 to 130 are crossed with each other at intervals of a predetermined number of stitches between the surface warp threads 111 and the back surface warps 121, The back yarns 110 and 120 are formed in such a manner that the constricted portion 140 and the protruding portion 150 are alternately arranged in the weft direction at regular intervals.

5 to 6, the shrinkage portion 140 is formed by weaving the front and back warp yarns 111a and 121a made of a large number of stock yarns with the front and back weft yarns 112 and 122, Is formed to be shorter than that of the ridge portion 150.

The raised portion 150 is made of a low shrinkage yarn and the back side warp yarns 111b and 121b are woven with the front and back weft yarns 112 and 122 so that the length L of the unit warp and warp slope is longer than that of the shrinkage portion 140 And has a sense of volume.

The method of manufacturing a double shrink fabric according to the present invention as described above may be applied to the surface fabric 110 and the back fabric 120 at the fabric made up of the surface fabric 110, the cushion layer 130 and the back fabric 120 It is possible to more easily manufacture the double shrinkage fabric having the shrinkage portion 140 and the protrusion portion 150, which is advantageous in that the process can be greatly shortened and the productivity can be improved as compared with the prior art.

Particularly, as in the prior art, the present invention is different from the conventional method in which a saddle-stitching yarn is stitched on a woven fabric, or a multi-layered fabric having different shrinkage ratios is stitched and heat- (S 10 to S 40) at the same time, and after finishing the process (S 50), the texture (wrinkle, volume feeling) of the desired bar is applied to the surface of the fabric It is more natural and evenly semi-permanently derived, so that there is an advantage that a high quality double shrinkage fabric can be manufactured more easily.
