Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a novel loosely dyed fabric exhibiting an elegant appearance and a method for producing the loosely dyed fabric at a relatively low cost using an ordinary mechanical printing process. It is.

Conventional unraveling fabrics are made by printing on a sheet-like group of warp yarns in which the weft yarns are woven extremely coarsely to prevent the warp yarns from coming apart.Then, the weft yarns are removed, regular weft yarns are inserted, and the warp yarns are woven. It was manufactured using a very complicated process in which the outline of the printed pattern was made uneven by the difference in tension between the two. For this reason, workers are required to have highly skilled techniques, and the amount of production is limited, making the fabrics extremely expensive.

The present inventors have invented a new loose-textured fabric and a method for obtaining such a loose-textured fabric without complicated processes and without requiring a high level of technical skill.

That is, in the present invention, two or more types of synthetic fiber multifilament yarns having different t#4 shrinkage percentages as warp threads are arranged in an appropriate order and woven, and then a textile pattern is provided with a high shrinkage ratio. It is a loosened mediation dyed fabric characterized by only the threads moving in the yarn length direction and the outline of the printed pattern forming unevenness, and also a composite of two or more types of warp yarns with different heat shrinkage rates. A method for producing a loosened printed fabric, characterized by arranging fiber multifilament yarns in an appropriate order and weaving them in a plain weave structure, then performing a printing process, mechanically shifting the high shrinkage yarns, and performing a finishing process. be.

The present invention will be explained in detail below.

In the present invention, two or more types of synthetic fiber multifilament yarns having different heat shrinkage rates are used as warp yarns. The two or more types of synthetic fibers having different heat shrinkage rates may be, for example, fibers of the same type but with different heat shrinkages, or fibers of different types with different heat shrinkages. In this case, it is desirable that the difference in water shrinkage rate between the high shrinkage yarn and the low shrinkage yarn is 4% or more. Further, the surface effect will be better if the thickness of the high shrinkage yarn is at least twice as thick as that of the low shrinkage yarn. In addition, for the distribution of high-shrinkage yarns and low-shrinkage yarns, the hogshi effect is greater when the total number of high-shrinkage yarns is equal to or less than the total number of low-shrinkage yarns, but if the difference is less than 1/3 , the effect will be smaller, which is not good. The method of arranging high-shrinkage yarns and low-shrinkage yarns is that if one yarn of each is arranged alternately, warp misalignment is less likely to occur, so it is necessary to alternate at least two yarns, and to avoid a rough surface appearance. for? '110 or less alternately is desirable.

In addition, the number of twists of low shrinkage yarn is 1500-3500 times/m (
7) When using highly twisted yarn, after weaving, the fabric is subjected to impact in hot water, which develops the latent swirling force of the yarn, which increases the difference in edge width, length, and length during finishing. This is preferable because the high-shrinkage yarn is likely to "slip" and a better loosened texture can be obtained.

The weft may be any yarn, but it is preferable to use a yarn with a shrinkage rate comparable to that of the low shrinkage yarn of the warp.

It is woven into a plain weave using the warp and weft described above. If the fabric density is too high, "zun" of high shrinkage yarn will not easily occur,
Moreover, if it is too low, a so-called slip phenomenon may occur, which may impair commercial value. For example, if the low shrinkage yarn used for the warp and weft is 50 denier, the fabric density is 2.54 c
80 or more warps and 150 or less warps per m, 70 or more wefts 1
In addition, when the low shrinkage yarn is 75 denier, it is preferably 70 to 130 warp yarns and 60 to 90 weft yarns.

Printing may be carried out by a normal printing process, but transfer printing that involves high temperatures should be avoided. All of the coloring, fixing, washing, and drying steps can be carried out in the usual manner, and there is no need to use special equipment or conditions. The final finishing machine may be any ordinary equipment, but it is necessary to mechanically shift only the high shrinkage yarns constituting the woven fabric, that is, to partially apply tension.

A tensioning device having an uneven surface is effective as a device for partially applying tension to the printed fabric. The same effect can be obtained by rotating the Tensilan device or by keeping it stationary. Further, when the pressure of the cloth is strengthened, the hogshi effect becomes stronger, and when the pressure is weakened, the hogshi effect becomes weaker.

The unraveling 'A printed fabric according to the present invention is obtained by the difference in heat shrinkage of the warp threads and by mechanically shifting the warp threads. A pattern with delicate uneven contours that cannot be obtained with textiles is formed.

In this application, the heat shrinkage rate was calculated based on J Engineering SI, -1073.

Example 1 Warp: 50 denier 36 filament with water shrinkage rate of 4%, polyester multifilament with twist number of 2700 T/M Kenjin + Itp 150 denier 48 filament with water shrinkage rate of 12%, polyester multifilament with twist number of 1000 T/M Using yarn B, 4 A yarns and 2 B yarns are arranged in a repeating manner, and the weft is a 50 denier 36 filament yarn with a ring water shrinkage rate of 4 meloes and a polyester multifilament yarn with a twist number of 3000 T/M. A plain weave fabric with a density of 120 17'2 yarns, a 54 cmsm weft density of 78 yarns, and a density of 546 nm was woven. After applying an impact to the fabric in hot water at 120°C to develop the latent swirling force of the yarn,
Printing is done using a flat screen printing machine, the color develops and fixes,
After that, using a finishing tenter, the fabric was crimped onto a tensilan device with uneven surfaces and finished by applying uneven tension locally in the warp direction, making it possible to obtain a loose-textured fabric with an ambiguous appearance. Ta.

Example 2 As the warp, 75 denier 72 filament with a drainage shrinkage rate of 2%, polyester multifilament pre-inserted with a twist number of 2500T/M, and 150 denier 4B with a drainage shrinkage rate of 12%.
Using filament and polyester multifilament yarn B with a twist number of 1000 T/u, A12, B4, A6
Book, B are arranged in two repeats, and the weft is a 75 denier 72 filament with a drainage shrinkage rate of 2%, the number of twists is 25
Using 00T/M polyester multifilament yarn, the warp density is 100. ? A plain weave fabric with a weft density of 1C/2.54crn and a weft density of 68/2.54crn was woven. When the plain weave fabric was finished in the same manner as in Example 1, it was possible to obtain a loosened fabric with an elegant appearance.
