Embodiment

[0030] A preparation method of functional strong-twisted color-dot silk, comprising the steps of:

[0031] Step 1, preparation and dyeing of cupro ammonia fiber filaments: dissolving natural cellulose raw materials such as cotton linters in the concentrated ammonia solution of copper hydroxide or alkaline copper salt, making spinning solution, and dissolving them in water or dilute alkali solution Spinning and forming in the coagulation bath, and then in the second bath containing 2-3% sulfuric acid solution, decompose the molecular chemical substances of cupro ammonia fiber to regenerate cellulose, generate hydrated cellulose, and obtain cupro ammonia fiber after post-processing; and carry out Dyeing treatment.

[0032] Step 2, UHMWPE filament coloring treatment:

[0033] In this method, the organic pigment solution and the ultra-high molecular weight polyethylene fiber spinning stock solution are co-extruded in a twin-screw extruder. Because the internal temperature of the ...

Abstract

The invention discloses a method for preparing functional highly-twisted color dot yarn. The color dot yarn prepared by means of the method is formed through the steps that color fibers are intermittently implanted in the process of twisting filaments, discontinuous color dots are formed on the surfaces of the filaments, and the thickness and length of the color dots can be controlled. The color dot yarn has more changes in the color of the yarn, the three-dimensional feeling of the yarn is stronger, more changes are provided for the style of fabric, the variety of the filaments is enriched, and the progress and development of a filament technology are promoted. In the prepared color dot yarn, copper ammonia fiber filaments and ultra-high molecular weight polyethylene fiber filaments adopted as the filaments, and after being highly twisted, the filaments have the performance of cooling, air permeability, moisture absorption, high strength, wear resistance and the like; in the twistingprocess, luminous fiber color dots with two colors are added, the luminous fibers can emit light in the daytime and at night, different colors are presented, and the color richness and three-dimensional feeling of the highly-twisted yarn are improved; by means of the method, the application of the functional fibers is promoted, and the design of textile products is enriched.

Description

technical field [0001] The invention belongs to the field of spinning, and in particular relates to a preparation method of functional strongly twisted colored dotted yarn. Background technique [0002] The raw material of cupro viscose is extracted from the short fluff of cottonseed in cotton. The cupro fiber is easily decomposed by bacteria in soil and water, and will not damage the natural environment. Even if it is burned, no toxic gas will appear, which is in line with the current environmental protection trend "Green Fiber". [0003] Cupro viscose has a good moisture absorption and release effect, and it feels soft and delicate in contact with the skin. In addition, it has anti-static function and has a good touch feeling, which can avoid stuffy and uncomfortable feeling. Copper ammonium viscose fiber has four functions: breathing, refreshing, antistatic, and good drapability. Its most attractive feature is that it is hygroscopic and dehumidifying, and it is a breat...
