Problems solved by technology

[0002] Cotton fiber fabrics have the following problems: lint is generated when part of the surface falls off, and even when dyed with a dark dye, it is difficult to form a dark color, and it appears to be whitish and fuzzy, and the color is not deep
[0013] However, if the previously used mercerizing process for the purpose of improving the dyeability of cotton fibers is performed on composite fiber products formed of cotton fibers and regenerated cellulose fibers, the hardening of the regenerated cellulose is large, and the dead hair on the surface of the cotton fibers cannot be completely eliminated. , so there is a problem of difficulty in dark color dyeing
Therefore, the resulting product has little value as a commodity
[0014] In addition, for liquid ammonia processing or processing using amines, there is a problem that the dyeability cannot be improved.

Embodiment 1-1

[0080]As a cloth made of cotton fibers, use a 0.1% by weight aqueous solution of an anionic-nonionic mixed active agent (manufactured by Nikka Chemical, Sunmol BH-75) at 80° C. for 20 minutes, and then use hydrogen peroxide (35%) 15% by weight and 0.2% by weight of sodium silicate and 0.1% by weight of sodium hydroxide aqueous solution bleached cotton fibers (30 single yarn) under the condition of 90 ℃ * 60 minutes plain weave fabric. The plain weave fabric was dipped in a 20°C aqueous solution containing 45% by weight of potassium hydroxide for 60 seconds without applying tension, and then subjected to two 10-minute hot water washes at 80°C. Next, neutralization was carried out at 80° C. for 10 minutes with a 0.05% by weight aqueous solution of acetic acid to completely remove the alkali. After that, SUMIFIX BLACK E-XF (manufactured by Sumitomo Chemical Industries, Ltd.) at a concentration of 5% owf (% by weight of the dye compound relative to the weight of the fiber) was use...

Embodiment 1-2

[0085] The same fabric as in Example 1-1 was immersed in 5% by weight of sodium hydroxide, 40% by weight of potassium hydroxide and an anionic surfactant (manufactured by Daido Synthetic Chemical Industry Co., Ltd. S0600) in a 5% by weight aqueous solution for 60 seconds, then perform two 10-minute hot water washes at 80°C, and then neutralize with 0.05% by weight acetic acid aqueous solution at 80°C for 10 minutes to completely remove the alkali. Then dye with the same prescription as Example 1-1. The evaluation results are shown in Table 1.

[0086] As shown in Table 1, by adding a surfactant as a penetrating agent, the surface tension of the treatment liquid becomes 30 dyn / cm 2 , and the same as Example 1-1 before adding surfactant, about 70dyn / cm 2 . In addition, the treatment was carried out until the coefficient of static friction was about 56% of the unprocessed product. In Example 1-2, all aspects of dyeability, gloss, and pilling were superior to those of Example ...

Embodiment 1-3

[0089] Tension was applied and treated under substantially the same conditions as in Example 1-2. That is, the same fabric used in Example 1-1 was immersed in 5% by weight of sodium hydroxide, 40% by weight of potassium hydroxide, and an anionic surfactant (manufactured by Daido Synthetic Chemical Industry Co., Ltd., Daido) under tension. 1 ルS0600) 5% by weight aqueous solution for 60 seconds, followed by two 10-minute hot water washes at 80°C, and then neutralized with 0.05% by weight acetic acid aqueous solution at 80°C for 10 minutes to completely remove the alkali. Then dye with the same prescription as Example 1-1. The evaluation results are shown in Table 1.

[0090] As shown in Table 1, although the treatment liquid was the same, by applying tension, the decrease in the coefficient of static friction was slightly larger than in the case of Examples 1-2. However, the dyeability, luster, pilling property, and touch were all the same as in Examples 1-1 to 2 and the like....

Abstract

Manufactures cotton fibers and fabrics containing cotton fibers with a glossy surface, soft touch, and excellent dyeability. Or when dyeing yarn or cloth containing both cotton fibers and regenerated cellulose fibers, the uniformity (same color) of the degree of dyeing between cotton fibers and cellulose fibers can be improved without impairing the hand feeling , and impart sufficient dyeability. Through the aqueous solution of potassium hydroxide whose surface tension is less than 75dyn / cm2, the yarn or cloth is treated under the condition of no tension until the static friction coefficient of the cotton fiber surface is 50-75% of the unprocessed product. Or process under tension until the coefficient of static friction is 40-65% of the unprocessed product.

Description

technical field [0001] The present invention relates to a method for the manufacture of fiber products containing cotton fibers. First, it relates to a cotton fiber product having excellent hand feeling, luster and dyeability, and more specifically, to a method for producing a cotton fiber product with a smooth fiber surface. The cotton fiber products here are yarns, cloth and raw cotton containing cotton fibers. Next, the present invention relates to a method for producing a fiber product having improved dyeability (same color) without impairing softness of a composite fiber product made of cotton fibers and regenerated cellulose fibers. technical background [0002] Cotton fiber fabrics have the following problems: lint is generated when part of the surface falls off, and even when dyed with a dark dye, it is difficult to form a dark color, and it appears in a whitish and blurred state, and the color is not deep. [0003] Therefore, so-called "mercerization" (mercerizati...
