Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a fiber structure having a wrinkle pattern.

[0002]

2. Description of the Related Art Conventionally, methods for producing fiber structures having various wrinkle patterns have been studied. For example, JP-A-48-
Japanese Patent No. 968887 discloses a method of bundling a cloth in a rope shape and / or forming an indentation crimp, and dyeing the cloth at the same time as or immediately after that to develop a wrinkle pattern on the cloth, and JP-A-59-15582. The publication discloses that when a dye or pigment is applied to a three-dimensional woven or knitted fabric by a padding and / or coating method, the woven or knitted fabric is pressed at the time of pressing by the method.
˜75% overlapping padding and / or coating to develop a wrinkle pattern, and in Japanese Patent Laid-Open No. 1554059/1990, a cloth made of synthetic fibers is subjected to hot water treatment at 90 to 140 ° C. in a rope state. Then, a method of coating a solution containing a pigment and then kneading the solution to develop a wrinkle pattern is also disclosed in JP-A-49 / 49
No. 13484 discloses a solid dye composition comprising a dye and an organic medium having a low melting point which is at least partially compatible with the dye, which is randomly applied to a cloth and pressed and melted on a heating roller. Then, a method of randomly applying the composition to the heating roller and press-melting the composition to adhere the composition to transfer the composition to the cloth to develop a dyeing pattern is proposed.

[0003]

However, the methods disclosed in JP-A-48-968787 and JP-A-59-15582 are for dyeing in a wrinkled state at the time of dyeing, and are therefore partially dyed. However, it has the drawback that white space may remain. Further, the method disclosed in JP-A-2-154059 has a defect that the texture is hard because a binder is used to fix the pigment. In addition, JP-A-49
The method of -13484 has the drawback that it requires special measures to randomly apply a solid dye composition consisting of a dye and an organic medium onto a fabric or heating roller.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method capable of obtaining a fiber structure having a wrinkle pattern with good operation stability and at an industrial cost.

[0005]

Means for Solving the Problems The above-mentioned object is to perform a wrinkling process on a cellulosic fiber structure, then to carry out a caustic treatment, and then to dye the fiber structure having a wrinkle pattern. It is achieved by the manufacturing method of.

The present invention will be described in detail below.

Examples of the cellulosic fibers applicable to the present invention include cotton, rayon, polynosic, cupra, and refined cellulosic fibers (trademark: TENCEL). However, cotton is preferable in terms of processing effect and strength reduction. Is preferred. Of course, other synthetic fibers may be mixed together.
Examples of the fiber structure include woven fabric, knitted fabric, and non-woven fabric. Such a cellulosic fiber structure is subjected to a pretreatment process such as hair burning, desizing, scouring and bleaching by a known method.

First, the cellulosic fiber structure as described above is subjected to wrinkling. For wrinkling, the wrinkling may be performed by grasping it with a hand or using a wrinkling processing device. The apparatus used for wrinkling is not particularly limited, but it is a jet dyeing machine, a mangle, a heated embossing roll, and JP-B-5.
6-5867 is sandwiched between tapered guide devices having upper and lower guide edges which mesh with each other to give a vertical wrinkle to the fabric, and then the fabric is pushed in an intermittent corrugated shape to cross it. A device configured to give wrinkles, Japanese Patent Publication No. 59-
The cloth described in Japanese Patent No. 39548 is rubbed against the rotating surface of a rubbing roller, which is formed in a conical shape and has projections that are screwed in opposite directions on the outer peripheral surface so that the cloth width is automatically retracted. A vertical wrinkle is caused on the fabric, and then a pair of feed rollers is stuffed in a form of overfeed between a pair of conveyors circulating at a surface speed reduced from the surface speed of the feed rollers to proceed. A device that bends in the direction to form horizontal wrinkles and fixes vertical and horizontal wrinkles.
The fabric described in Japanese Patent Publication No. 20 is folded by a plurality of folds extending substantially in the vertical direction, and the fabric folded in this manner is passed through the first mangle in a rope shape, whereby the folds in the vertical direction of the fabric are crushed and unfolded. Forming regular longitudinal creases, then folding the fabric laterally and then passing through a second mangle to collapse the transverse folds of the fabric to form irregular lateral creases. Device, JP-A-1-
Guide the cloth to the guide pipe described in 2015573,
An example is a device that pushes this cloth into a guide pipe with a stamp rod having a columnar projection at its tip, and pokes the cloth with the columnar projection.

The caustic treatment referred to in the present invention is equivalent to so-called mercerizing processing performed under tension.
Alkali treatment is achieved by applying an aqueous solution of caustic alkali to the wrinkled fiber structure by spraying, padding, etc., and performing tension treatment as necessary. In the present invention, the concentration is in the range of 150 to 350 g / l, preferably 1
It is in the range of 80 to 300 g / l. When the concentration is less than 150 g / l, a remarkable wrinkle pattern is not obtained after dyeing, while when the concentration exceeds 350 g / l, the texture becomes hard, which is not preferable.

After the alkali treatment, dyeing is carried out by a known method. For example, as dyes, reactive dyes, vat dyes, direct dyes, etc. may be used for immersion dyeing with a jet dyeing machine, wince dyeing machine, beam dyeing machine, Jigga dyeing machine, etc., or continuous dyeing with a continuous dyeing machine etc. Although dyeing is performed, the immersion dyeing is preferable because a wrinkle pattern is remarkably exhibited.

EXAMPLES The method of the present invention will be specifically described based on examples.

Example 1 In this example, a fibrous structure having a warp density of 50 count single yarn and a weft count of 50 count single yarn and having a warp density of 125 yarns / inch and a weft density of 85 yarns / inch was used. Using. The plain weave was fried, desizing, scouring and bleaching by known methods. Then, using a jet dyeing machine, a temperature of 100
It was subjected to wrinkling at a bath temperature of 1:10 at a temperature of 1 ° C., dried in a tumbler drier, and subsequently subjected to caustic alkali treatment using 200 g / l of caustic soda, followed by hot water washing and water washing. The plain woven fabric was dyed yellow with a reactive dye using a jet dyeing machine by a known method to obtain a product of Example 1.

The product obtained in Example 1 had a noticeable wrinkle pattern.

Example 2 In this example, a warp density of 125 yarns / inch composed of a warp yarn 50 count (65% polyester, 35% cotton) and a weft yarn 50 count (65% polyester, 35% cotton) was used as a fiber structure. A polyester / cotton blended plain weave fabric having a weft density of 85 filaments / inch was used. The plain weave was fried, desizing, scouring and bleaching by known methods. Then, using a jet dyeing machine, a wrinkle process was performed at a temperature of 120 ° C. and a bath ratio of 1:10, followed by drying with a tumbler dryer, followed by a caustic treatment with 200 g / l of caustic soda, and washing with hot water. It was washed with water. The plain woven fabric was dyed red by a known method using a jet dyeing machine using a disperse dye and a reactive dye, and Example 2
Got the product.

The product obtained in Example 2 had a noticeable wrinkle pattern.
