Problems solved by technology

This kind of spinning method has high yarn evenness, many details, insufficient strength, and easy yarn breakage. The yarn production rate is low by 1.34, and the cost increases. The product sticks to the lap, it is difficult to form a web, the phenomenon of wrapping rollers is serious, and the uneven mixing leads to uneven fiber distribution in the yarn body, large hairiness on the fabric surface, and it is very easy to have holes, and there are too many neps on the fabric surface, which affects the fabric surface. quality

Embodiment

[0037] A preparation method of modal polyester fine cotton seaweed yarn, comprising the steps of:

[0038] (1) Preparation of pre-blended cotton rolls: prepare pre-blended cotton rolls with modal fiber and seaweed fiber at a weight ratio of 90:10; specifically: weigh modal fiber and seaweed fiber at a weight ratio of 90:10 Weigh, spray antistatic liquid evenly on the modal fiber, and let it stand for 6 hours; evenly spray and crude oil (commercially available) on the seaweed fiber, and stuff it with a plastic bag for 12 hours; then, mix the two fibers , the disc mixing is specifically to place the modal fiber and seaweed fiber on the disc of the disc catching machine, and use the gripper of the catching machine to grab it; On the mixed opener, small porcupine beaters and parallel beaters are used to remove harmful defects in the fibers; then, in the cotton opener, comb needle beaters are used to continue opening and removing impurities, and at the same time, the cotton roller ...

Abstract

The invention discloses a preparation method of modal polyester refined cotton seaweed yarns. The preparation method comprises the steps of (1) preparing a premixed cotton roll; (2) preparing pure polyester card slivers; (3) preparing a mixed cotton roll; (4) preparing mixed card slivers; (5) preparing combed cotton slivers; (6) performing primary drawing; (7) performing secondary drawing and final drawing; (8) forming roving; (9) forming spun yarn; and (10) finally, removing yarn faults and forming a bobbin by adopting an automatic winder. The formed yarn has the advantages of low neps, few thick and thin threads and less hairiness, the utilization rate of raw materials can be improved by 100%, the yarn yield is improved to 1.02, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a method for preparing modal polyester fine cotton seaweed yarn. Background technique [0002] The raw material of Modal fiber comes from natural wood, which can be naturally degraded after use. The fineness of Modal fiber is 1dtex, while the fineness of cotton fiber is 1.5-2.5tex, and the fineness of silk is 1.3dtex. Modal fiber is soft, smooth, bright in color, the fabric feels very soft, the surface of the fabric is bright and shiny, and its drapability is better than that of existing cotton, polyester, and rayon. It has luster and hand feeling. It is a natural mercerized fabric. Modal fiber has the strength and toughness of synthetic fibers, with a dry strength of 3.56cn / tex and a wet strength of 2.56cn / tex. The strength is higher than that of pure cotton and polyester cotton, which reduces the phenomenon of broken ends during processing. The moisture abs...
