[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fabric in which a pattern is formed on the surface of the fabric by partially varying the relaxation effect with respect to the cellulosic fiber fabric in the form of a pattern.

[0002]

[Prior art]

 Conventionally, as a method of imparting a design to a cloth, in addition to a method of coloring, for example, a method of printing, a thread dyeing, etc., a method of expressing a pattern by the structure of a woven or knitting method, for example, a method using a jacquard, or a chemical treatment is used. There are known a method of partially dissolving or shrinking a part in a pattern, and a method of causing a strain in a tissue by performing a partial heat treatment in a pattern with an engraved heat roll or the like.

However, although these methods have many advantages, they have a big problem in industrial production. For example, in the case of expressing or forming a design by the structure of weaving or knitting, it is necessary to incorporate a special device capable of forming a design by the structure in the loom or knitting machine or install it as an auxiliary device. The composition of the design depends on the performance of the device for forming the design and is limited.

Further, when a pattern is formed by a chemical treatment, the chemical treatment causes the strength of the cloth itself to be partially reduced, but there is a high risk that the quality becomes unstable. When a pattern is formed by partial heat treatment with a hot roll, it is necessary to manufacture an expensive chilled roll engraved according to the pattern. In addition, this chilled roll is heated at a high temperature, for example, of a polyester fiber cloth. In this case, it is necessary to heat to 150 to 195 ° C., and to control the variation in temperature to be shivering. In other words, in the method using chemical treatment and heat roll, the clearer the pattern, the less the feeling of thickness and unevenness of the fabric, and the more easily the strength of the fabric decreases. . Further, in the case of cellulose fiber cloth, such a method, that is, a method of forming a pattern by a chemical treatment or a heat roll could not express a durable uneven feeling itself, so that the pattern was expressed. There was no cloth.

[0005]

[Problems to be solved by the device]

 The purpose of the present invention is to eliminate the above-mentioned conventional problems, and in particular, there is no decrease in strength due to embrittlement of the pattern forming portion of the fiber cloth, and there is a sharp pattern with unevenness. It is to provide a strongly twisted yarn fabric having

[0006]

[Means for Solving the Problems]

 As a result of diligent research on such problems, the present inventor applied a pattern forming agent containing caustic soda according to the desired design before relaxing treatment on the strongly twisted yarn fabric, and then relaxed the fabric. The inventors have completed the present invention by finding that it is possible to cause a difference in relaxation effect in the form of a pattern and form a clear and uneven pattern on the surface of a fabric without a decrease in strength.

That is, the present invention relates to a cellulosic fiber cloth characterized in that a pattern is expressed by partially expressing the untwisted state of the twisted thread in the fiber cloth containing the twisted thread in at least a part thereof. is there. Specifically, in the present invention, a pattern forming agent containing caustic soda is applied to a woven or knitted fabric using a cellulosic strong twisted yarn in a state close to a raw machine in a pattern according to the desired pattern, and then dried. Then, by relaxing with a washer or the like, a partially different treatment effect is obtained to form a pattern on the surface of the cloth. In other words, the strong twisted yarn of the fabric develops a wrinkle due to the torque by the relaxation treatment, but when the pattern forming agent is applied to the surface of the fabric, the caustic soda contained in the pattern forming agent eliminates the torque of the strong twisted yarn. As a result, the subsequent relaxation process does not cause the appearance of wrinkles, and as a result, unevenness due to the presence or absence of wrinkles and a partially watermark-like pattern are generated.

[0008]

[Embodiment of device]

 The present invention will be described in detail below. (1) Fiber fabric subject to pattern formation The cellulosic fiber fabric subject to pattern formation in the present invention means, specifically, natural fibers such as cotton and hemp, viscose rayon, cupra rayon and modified. A woven or knitted fabric made from recycled fibers such as high quality rayon. Cellulose fibers and synthetic fibers may be used in combination. The mixing method at that time is mixed spinning, twisting, weaving, knitting, etc. There is no particular limitation.

(2) Preparation of pattern forming agent The pattern forming agent used in the present invention, that is, the pattern forming agent containing caustic soda applied or printed on the surface of the fabric can be easily removed during the relaxation treatment. Desirably, it consists of the following major components: a. Gluing agents There are substances that can withstand high concentrations of alkalis such as caustic soda and that have good desizing properties, such as soluble starch, sodium alginate, and carboxymethyl cellulose (CMC). b. Viscosity adjustment The optimum viscosity varies depending on the method of applying the pattern forming agent, but usually 2000 to 20000 cps is preferable. The viscosity is usually adjusted according to the concentration of the paste used. c. In addition, an antiseptic agent, an antifoaming agent, etc. may be added if necessary.

(3) Application of Pattern Forming Agent The method of applying the pattern forming agent in the present invention is not particularly limited as long as it can be applied according to the pattern for which the pattern forming agent is sought. There is a method using a printing equipment or a method using a gravure method or the like. When the conventional printing equipment is used, any method such as rotary screen printing, roller printing and screen printing may be used, and the target cloth made of cellulosic fibers can be used in a wide range. When the gravure method is used, the target fabric is somewhat limited as compared with the above-mentioned textile printing machine, but it is possible to express finely from clear patterns to partially blurred patterns.

(4) Drying Treatment of Cloth After Application of Design Forming Agent The drying treatment of the fabric after application of the pattern forming agent in the present invention is carried out at a drying temperature of 100 to 140 ° C. using an ordinary dryer for fabric. And

(5) Relaxation treatment The relaxation treatment after applying the pattern forming agent of the present invention is almost the same as the ordinary relaxation treatment in a bath, and is performed by a rotary-washer type relaxer or a jet type dyeing machine. The temperature of the processing liquid is room temperature to 80 ° C. The processing time is 30 to 90 minutes. As a result, the part to which the pattern forming agent is not applied during the relaxation process is relaxed by the relax process, that is, the wrinkle rising effect is exhibited by untwisting, and the part to which the pattern forming agent is applied is relaxed. The effect is not expressed. In other words, a pattern is formed by the contrast effect depending on the presence or absence of the textured effect. On the other hand, the pattern forming agent attached to the cloth falls off during relaxation.

(6) Intermediate Drying Treatment The intermediate drying treatment of the present invention, that is, it is possible to dye the fabric immediately after the washing treatment, but if the dyeing treatment is not necessary or the fabric is temporarily held, the drying treatment is performed. I do.

(7) Dyeing treatment The dyeing treatment of the present invention allows dyeing under the same conditions as for ordinary fiber cloth. That is, the dyeing conditions are set according to the constituent material of the cloth, the structure, the hue and the like.

(8) Finishing Treatment and Set In the finishing treatment and setting of the present invention, the finishing treatment and setting are performed under the same conditions as for ordinary cloth. That is, the conditions are set according to the constituent material and structure of the fabric, and a finishing agent is further added if necessary.

【Example】

 Next, the present invention will be described in detail by the following specific examples.

Example 1 As a test cloth, a warp and a weft were both viscose rayon yarns of 120 d, and the weft yarn was a strongly twisted yarn of S twist (2600 T / M), and the weft warp density was 109 yarns each. / Inch, 48 pieces / inch rayon Yangyanagi crepe was used. The coating liquid as a pattern forming agent was prepared as follows. Carboxymethyl Cellulose Sodium Complex Composite 12 parts [Fine Gum SDR-30 (Daiichi Kogyo Seiyaku Co., Ltd.)] Caustic soda 10 parts Water 78 parts ──────────────── ─────────────── Total 100 parts Incidentally, the viscosity of this coating solution was 10,000 cps. The above coating solution was applied in a pattern using a screen printing machine, and then dried by a dryer at 120 ° C. for 2 minutes. The dried cloth was subjected to a wet heat relax treatment at 50 ° C. for 60 minutes with a rotary washer, and after the liquid was drained, it was washed with room temperature water for 15 minutes. The cloth that had been washed with water was taken out and subjected to tenter-drying with a tenter type dryer at 130 ° C. for 2 minutes. After tentering and drying, the fabric was subjected to dyeing and finishing set under ordinary processing conditions of rayon Yangyanagi crepe. Results In FIG. 1, the part a is a part coated with the pattern forming agent, and the part b is a part not coated with the pattern forming agent. The portion a has a flat effect because the relaxing effect of the yarn is not expressed and the grain-like texture of the Yangyanagi is not generated, and the relaxing effect of the yarn is exhibited in the portion b and the effect is a Yangyanagi tone. Therefore, as shown in the figure, the portion a is represented as a clear pattern on the fabric surface.
