Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for producing a textured fabric, in which a fabric using synthetic fiber threads is partially textured by post-processing.

(Prior art) As a method for producing grain in textiles through post-processing, a paste prepared by mixing strong caustic soda is printed in an arbitrary pattern on a textile made of cellulose fibers such as cotton textiles, and the printed area is coated with the action of the caustic soda. A method of shrinking the printed area to create a grain around the printed area, a method of mixing a dye with the above paste and printing at the same time, shrinking the printed area and creating a grain around the printed area, and a method of resist printing. A known method is to apply paste and then immerse it in a caustic soda solution to create a grain in the resist-dyed area. On the other hand, any fabric is printed with a printing paste containing a condensation-type thermosetting resin, heat-treated to form a resin layer on the printed pattern area, and a shrink finish is applied to this to shrink the area other than the printed pattern. A method is known in which grains are produced in the printed pattern by

(Problems to be Solved by the Invention) The method using caustic soda can only be used for cellulose fiber fabrics such as cotton fabrics, cannot be used for synthetic fiber fabrics, and requires caustic soda.

In order to generate grain in the printed pattern, after the printed pattern has been printed, caustic soda paste must be printed on the outside of the printed pattern, which requires pattern matching. On the other hand, the method using a thermosetting resin requires a thermosetting resin (a resin layer of the thermosetting resin is formed and the texture changes, and the presence of the resin layer causes the grain to become rough). easy.

(Means for solving the problem) A woven fabric using synthetic fiber threads in at least one of the warp and weft is stretched in the direction of the synthetic fiber threads, and colored starch is applied to the stretched woven fabric in an arbitrary pattern. The fabric is printed in a shape, dried and solidified in a stretched state to fix the printed part of the fabric in a stretched state, and then the fabric is heated in a relaxed state to color the printed part and shrink the parts other than the printed part. Then, it is washed with water and dried to create a grain in the printed area.

(Function) When the colored paste on the stamped area is dried and solidified, and then heated in a relaxed state to develop color, parts other than the stamped area shrink due to heating, but the colored paste remains fixed in place. Therefore, it does not shrink. Therefore, when the colored paste is removed and the restriction on the printed area is released, a grain appears on the printed area.

The stretching ratio of the fabric during printing is preferably 3 to 30%; if the stretching ratio is less than 3%, no grain will be generated, and if it exceeds 30%, it will be too large and may break. In addition,
The synthetic fiber yarn can be in any form as long as it has an elongation of 3% or more, and it suffices if it is used in either the warp or the weft, and the woven fabric is stretched in the direction of the synthetic fiber yarn,
When synthetic fiber yarns are used as both warp and weft yarns, they can be elongated in both directions, and the method of using the synthetic fiber yarns is selected depending on the desired grain shape.

The glue used for the colored paste may be any glue that can maintain the printed area in an elongated state during the process of shrinking the area other than the printed area, such as starch paste, starch derivatives, CMC derivatives, bean gum, tragacanth gum, and crystal. One type of gum, British gum, etc., or a mixture thereof is used, and the mixing ratio is determined by taking into consideration factors such as size removal, color development, adhesive cutting, level dyeing, film strength, mold edge, etc.1 The viscosity of the colored paste is preferably 5,000 to 25,000 cp, and it is applied to the fabric to the extent that it passes through the back.

The printing may be done by rotary printing, machine printing, screen printing, etc., and the pattern of the printing can be vertically or horizontally striped, lattice-like, or in any other arbitrary shape.

Drying after printing is to dry and solidify to the extent that almost all the moisture in the color glue disappears, preferably at a dry heat of 100 to 120°C.The time varies depending on the fabric, but in the case of blouse fabrics, it takes about 5 minutes. Appropriate. Then, heating for color development is
It is carried out by steam or dry heat in a relaxed state; in the case of steam, the preferred temperature is 170-180°C for 7-8 minutes for 1 hour.

(Example) False twisted yarn made of polyester fiber (50 denier 3
6 filaments) are used for both warp and weft, warp density 42.1/c+s, weft density 36.6
After weaving a plain fabric of 1/l, relaxing it in hot water and reducing the alkali weight by 15%, we used a disperse dye at 110°C.
Discharge and unstaining was performed for 30 minutes. After underdying and drying, 160℃
Set the width to 113C11 and the weft density to 41.7 threads/am, then stretch this fabric by 6% in the warp direction to make the weft density to 39.4 threads/al, and in this state, machine print the fabric in the warp direction. Printed with a striped pattern. The colored paste used was 2 parts of disperse dye and 50 parts of original paste (CMC 8%).
Department.

It consisted of 0.2 parts of malic acid and 47.8 parts of hot water (100 parts in total), and the solid content was 45 g/rrr. Then,
Drying was performed for 5 minutes at 120° C. under the above-mentioned tension condition. Further, the product was steamed at 180° C. for 8 minutes without tension using a loop-type high-temperature steaming machine to develop color, and then washed with water and dried as usual to finish. As a result, grains appeared in the areas where the colored paste had been applied, and a soccer-like fabric that matched the color pattern was obtained.

(Effects of the Invention) By printing a woven fabric using synthetic fiber threads, grains are generated in the printed portion, and a woven fabric in which the printed pattern matches the grained portion can be obtained. The appearance of the grain differs depending on the stamped area; vertical stripes have a soccer-like appearance, streaks have a willow-like appearance, dotted patterns have a dechine-like or squeeze-like appearance, and one pattern has a bulge-like appearance. becomes.
