Description

Jacquard cloth using bi-shrink blended yarn {Jacquard Cloth}

The present invention relates to a woven fabric using two-shrink blended yarn and jacquard weave, and more particularly, to a fabric woven in a jacquard method (1,200 balls, 2,400 balls) using a two-shrink blended yarn. It shrinks according to the principle of high shrinkage and low shrinkage, and it relates to a jacquard fabric that has a low shrinkage due to high shrinkage and soft to the touch and forms various colors and patterns.

The conventional fabric using bi-shrink blended yarn is a synthetic fiber, which is similar to the appearance and feel of Korean Patent Application No. 1992-0001984, natural waste fabric to obtain the surface feel and appearance like natural silk. Republic of Korea Patent Application No. 1999-0038807 for the consumption tank having a, and the Republic of Korea Patent Application No. 1992-0023401 and 1997-0038628 for the suede fabrics that give the characteristics of natural suede touch and appearance.

Since the fabric using the conventional biaxial blended yarn is a common loom, Dobi does not form a jacquard pattern on the surface of the woven fabric. Therefore, in the conventional fabric using this shrink horn fiber, the pattern by the tissue can not appear, not by color, so the surface and appearance of the fabric is plain and plain without design. In addition, it is impossible to obtain the surface effect of the design and the design touch woven by jacquard except the touch according to the touch and the nature of the yarn itself.

Accordingly, the same applicant of the present invention applied for a 'patterned fabric using biaxial blended yarn' in 2006 and was determined to be registered in 2008. (Patent No. 10-0816862)

However, the above-described invention can realize various types of cover by forming a jacquard pattern to give a tactile feeling, but this is a characteristic of weaving only polyester yarns and bi-shrink blend yarns, and only dyeing after dyeing. There is a limit to trying.

In addition, in order to manufacture a moquette fabric that gives a luxurious feel such as velvet and suede, it is based on cotton yarn or fiber thread, and wool or fiber thread is used as a pile yarn to weave it into squid tissue to make long hair on the surface. It is to make a non-rod shape, the conventional moquette fabric had the disadvantage of missing hairs after the completion of manufacturing.

The present invention is to solve this problem, the problem of the present invention is that shrinkage action occurs when the heat is applied to the fabric woven by using a biaxial horn fiber yarn through a post-process, wherein the jacquard difference in the shrinkage phenomenon The purpose of the present invention is to provide a jacquard fabric that expresses a textile pattern but can express various colors through mixing of various materials and processing.

In addition, 1,200 or 2,400 ball Jacquard looms are used in the weaving of the fabric, and the jacquard fabric has a variety of textures ranging from soft to rough and bulky, depending on the number of crossings of warp and weft. .

In addition, even when manufacturing a moquette fabric that gives a luxurious feeling such as velvet, suede, it is intended to minimize the hair fall from the moquette fabric after the manufacture is completed.

In order to solve the above problems, in the present invention, in the woven fabric to form a pattern on the surface by using a jacquard machine, a high shrinkable fiber made of a polyester copolymer for the warp yarn, a natural fiber for the weft yarn, and between the warp yarn and the weft yarn After weaving the fabric forming the pattern part and the bottom part according to the ratio, the refining process is carried out to form the pattern skin loops on the surface, and the bottom part is the bishrink horn manufactured to form the pitch skin loops on the back side. A jacquard fabric is provided using yarn.

According to the present invention configured as described above, by applying heat to the fabric woven by blending yarn for a predetermined time to cause a shrinkage action, it is possible to form a variety of patterns by the shrinkage difference between the low shrinkage fibers and high shrinkage fibers.

In addition, when weaving the fabric using a Jacquard (Jacquard) method, it is possible to provide a fabric having a variety of touch, from a soft touch to a rough and bulky feeling depending on the number of crossings of warp and weft.

In addition, since the fabric can be manufactured by performing a dyeing operation on each of the highly shrinkable fibers and the low-shrinkable fibers, various colors can be given to the finished product, thereby improving aesthetics.

In addition, through the buffing and shirring process, it is possible to give the jacquard fabric a mocket effect that gives a luxurious feeling such as velvet and suede, and when manufacturing the moquette fabric according to the present invention stably without hairs by buffing and shearing processing maintain.

Hereinafter, a preferred embodiment of the jacquard fabric using the blended yarn according to the present invention will be described in detail.

Figure 1 shows the blended yarn before shrink processing, Figure 2 shows the blended yarn made of shrink processing.

The blend fiber used in the present invention is a fiber in which a high shrink fiber and a low shrink fiber are interlaced.

At this time, the high-shrinkable fiber is applied to the polyester chemical fiber of 90 to 150 denier 24-72 filament, the low-shrinkable fiber is applied to natural fibers of 100 to 1000 denier.

Such mixed fiber is twisted as shown in Figure 1 by the hollow 30 is formed in the interlace spacing is to increase the apparent fineness.

When weaving the jacquard design using a blended yarn in which the highly shrinkable fibers and the low-shrinkable fibers are mixed, the fiber shrinks through refining shrinkage. As shown in FIG. The sinking, relatively low shrinkage fibers 20 made of natural fibers rarely shrink and rise to the surface to form a micro pitchskin loop.

As such, when the natural fiber is used as the low-shrinkable fiber, it is collected from nature, and thus environmental pollution is less, and even when disposed after use, it is easy to decompose and thus does not pollute the surrounding environment, thereby making it possible to manufacture environmentally friendly fabrics.

However, the natural fiber has a disadvantage that its strength is relatively weak, in the present invention, polyester high shrink fiber can compensate for this.

[Example]

3 and 4 respectively show the front and back of the jacquard fabric according to the embodiment of the present invention, Figure 5 is a block diagram showing the process of the present invention in order.

The fabric according to this embodiment is woven in a jacquard loom (Jacquard loom), wherein the number of looms are used 1200 spheres, 2400 spheres.

For the warp yarns, a biaxially blended blend of a polyester copolymer of 240 denier 96 filaments and natural fibers is used. As a weft yarn, ordinary natural fibers are used. Since natural fibers are used in the weft yarns as described above, diversification of the yarns can be achieved, and environmentally friendly fabrics can be produced.

In the weaving process, wefts are alternately transferred to the warp yarns, and the warp and weft yarns are crossed at intervals of 5 to 10 sheets. Here, the five-piece tissue is alternately engraved in such a way that when the weft enters the warp, the four wefts go up the warp and one piece goes down the warp.

At this time, according to the formation of the pattern, the weft yarn can go up and down than the inclination can be set differently. That is, as shown in Figure 3, the pattern portion 40, which forms a pattern on the front surface, the four weft yarns go up than the inclination, one sheet goes down, while the bottom portion 50, which does not form a pattern as shown in Figure 4, one weft yarn is inclined It goes up, and four pieces go down. (S2)

On the other hand, in the present embodiment, the natural fiber is included as the yarn, but before weaving, the biaxial shrink fiber and the natural fiber can be fabricated, such as ombre, respectively, so that fabrics of various colors can be obtained after weaving is completed.

Next, after weaving, heat treatment is performed to move the fabric at a speed of 15 to 25 yards / min under environmental conditions of 150 to 170 ° C. At this time, the fabric is reduced by approximately 10 to 20% in length by the contraction action of the warp yarn composed of biaxial intertwined yarn, the width is reduced by approximately 15 to 20% due to the nature of the tissue formed by the cross weft and weft yarn (S3).

At the same time, due to the difference in shrinkage between the shrink shrink yarn and the natural fiber, the shrink shrink blend yarn sinks and the natural fiber floats to the surface, and the surface of the fabric has a micro pitch skin effect that gives a soft surface texture similar to wool appearance. Accordingly, as shown in FIGS. 3 and 4, the pattern part 40 has a loop on the surface (front direction), and the bottom part 50 has a loop on the back surface (back direction), so that a pattern having a unique touch is formed. Is formed. In the case of the fabric woven at intervals of 5 sheets, the tissue is densely formed, so that the surface loop is uniform and fine.

In addition, it is possible to make the fabric feel softer and richer by buffing the nap on the loops to create a peach-like surface on the fabric surface. For this buffing process, a large, seamless sandpaper (belt type) is rotated at a high speed (40 to 45 M / min) in a rotatable manner, causing friction with the fabric and buffing (S4).

Next, the surface of the fabric irregularly raised on the surface of the fabric due to the buffing process to cleanly cut to the desired height of the hair to cut the ends of the hair through a shearing operation to enhance the feel and visual effect of the fabric. (S5)

As described above, the jacquard fabric using biaxial horn sum yarn and natural fibers, which have undergone buffing and shirring, can be applied to clothes, sofas, etc. by giving a mocket effect to give a luxurious feeling such as velvet and suede. In this case, when manufacturing the moquette fabric according to the present embodiment, since the hair is stably maintained by buffing and shearing processing, the hair does not fall out unlike the fabric exhibiting the existing moquette effect.

After that, if necessary, roller-type calendering, which is a uniform work of surface treatment, improves gloss, smoothness of fabric, and flexibility, and commercializes it directly (S6) or by applying a secondary coating process according to the use of the cover paper. Air permeability, durability, etc. can be improved. (S7)

On the other hand, in the embodiment of the present invention has been described with respect to the embodiment of applying the diaxial horn mixed yarn to the warp, it is also possible to use a diaxial horn mixed yarn for the weft, not the warp and to use natural fibers in the warp.

1 and 2 are schematic diagrams showing biaxial intertwined yarns before and after shrinkage processing, respectively.

3 and 4 respectively show the front and back of the jacquard fabric according to the present invention.
