Problems solved by technology

Although it is mentioned in CN101413213A that cotton fiber can be mercerized in liquid ammonia under tension, there is no specific practical condition, and a truly feasible way has not been found, so only the theoretical basis lacks the conditions for implementation

Abstract

The invention relates to a mercerizing fiber and a processing method of the mercerizing fiber and belongs to the technical field of textile. The processing method of the fiber liquid ammonia mercerization comprises steps as below: fiber mercerization, rope braid weaving, pre-drying, liquid ammonia mercerization, drying and steaming and rope braid degradation. The fiber mercerization means that fibers are manufactured into fiber strips through a conventional spinning process. The rope braid weaving means that a plurality of untwisted fiber strips are mutually weaved to form rope braid shaped structure according to certain rules, such as a ponytail-shaped rope, a braid-shaped rope. The pre-drying means that the liquid-carrying rate of the fiber is reduced below 3%. The liquid ammonia mercerization means that fiber rope braids after pre-drying complete liquid ammonia mercerization. The drying and steaming means that ammonia carried by the fibers after padding is removed to reduce the ammonia content of the fibers. The rope braid degradation means that the fiber rope braids after steaming are degraded into single fiber strips to be used for spinning into yarn in followed step. The steps of obtaining of the slurry-free woven materials by utilizing the above mercerizing fibers are as follows:spinning, slurry-free weaving and slurry-free woven material forming. Yarns formed by fibers after being processed by liquid ammonia are good in strength, low in hairiness, and are good in wear resistance. The fibers are spun into yarns and are used for the slurry-free woven materials, and therefore no slurry residues exist in the woven materials, and the fabrics have the advantages of being soft in touch, and silky.

Description

technical field [0001] The invention relates to the technical field of textiles, and relates to a method for mercerizing fibers and a prepared size-free woven fabric, specifically a method for mercerizing fiber strips with liquid ammonia and then decomposing them into fiber strips for spinning. The processing method of yarn, and then the yarn is used for size-free woven fabrics made by size-free weaving. Background technique [0002] The liquid ammonia finishing of fibers and fabrics is generally similar in effect to liquid alkali mercerizing, but caustic soda has high viscosity and uneven penetration, which makes fibers and fabrics feel hard and uneven dyeing, and the special structure of protein fibers makes it impossible to use caustic soda. Mercerized, otherwise the protein fibers will be severely damaged. Liquid ammonia is a bulking agent with good penetration performance, which can fully swell the surface of the fiber, remove uneven deformation to a greater extent, r...
