A functional core-spun yarn and its spinning process

Abstract

The invention relates to the technical field of spinning, in particular to functional covered yarn and a spinning technology thereof. The functional covered yarn is prepared by mixing, by weight, 10-30% of EKS fiber and 70-90% of ultrafine acrylic fiber to form core yarn, and the core yarn is wrapped by taiji stone viscose as yarn skin. The spinning technology of the functional covered yarn comprises the steps of 1 spinning a yarn core, 2 spinning the yarn skin and 3 combining the yarn skin and the yarn core, namely spinning the covered yarn. The functional covered yarn can lower the risk thata white part of a cloth cover is leaked due to the fact that EKS fiber is leaked out of the cloth cover, the functional covered yarn has the good anti-pilling effect and high water absorbability, hasthe effect of promoting the moisture absorption and heating function, meanwhile has the far infrared effect and further has the anti-ultraviolet and antibacterial advantages, and the spinning technology of the functional covered yarn has the advantages of being simple, low in production cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a functional core-spun yarn and a spinning process thereof. Background technique [0002] EKS fiber is a new type of fiber with moisture absorption and heating function developed by Japan Toyobo. In winter, it absorbs the moisture discharged from the human body and generates heat, which makes the temperature of the wearing space of the human body rise, making people feel warm and comfortable. A new fiber material is provided. However, non-dyeable EKS fibers have high rigidity, thick fibers, and are easy to swell after absorbing water. In the subsequent processing process, the fibers are easily transferred to the outside, exposing the cloth surface, so that the surface of the fabric is prone to white wool and old phenomenon, which reduces the fabric's durability. Wear aesthetics. [0003] In addition, the fabrics containing EKS fibers in the prior art also have the disadvantage...

AI Technical Summary

Problems solved by technology

However, non-dyeable EKS fibers have high rigidity, thick fibers, and are easy to swell after absorbing water. In the subsequent processing process, the fibers are easily transferred to the outside, exposing the cloth surface, so that the surface of the fabric is prone to white wool and old phenomenon, which reduces the fabric's durability. Wear aesthetics

[0003] In addition, the fabrics containing EKS fibers in the prior art also have the disadvantages of poor moisture absorption and lack of far-infrared effects.
