Three-dimensional light fiber embedded composite yarn and preparation method

Abstract

The invention discloses three-dimensional light fiber embedded composite yarn and a preparation method. The composite yarn comprises a yarn body, wherein the yarn body comprises four pieces of core yarn, a light fiber bundle and fasciated yarn; the four pieces of core yarn are distributed in a square shape; the four pieces of core yarn are symmetrically arranged by taking the center of the yarn body as a symmetric axis, and are spirally wound and stranded in the length direction of the yarn body; the light fiber bundle is formed by stranding light short fibers in parallel in a non-twist manner; the light fiber bundle passes through a space between two adjacent core yarn in the axial direction of the yarn body; the fasciated yarn is spirally wound outside the four pieces of core yarn. The method is simple and reasonable; light fibers are embedded in a yarn forming process of the composite yarn to form flocking-like yarn with a three-dimensional structure, so that the spinnability is good; meanwhile, the excellent characteristics of the light fibers can be brought into full play, and the composite yarn is soft, fluffy and smooth in touch, high in yarn strength, and good in heat retention property and using effect, and the hair is not easy to fall off.

Description

technical field [0001] The invention relates to the field of textile yarns, in particular to a three-dimensional lightweight fiber-embedded composite yarn and a preparation method thereof. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to the functional requirements of clothing. Health and comfort have become more and more people's basic requirements for clothing. Yarn is the basic material for making clothing, and the structure of yarn will directly affect the quality of clothing. Functionality and usability. Yarn is a kind of textile, which is processed into a certain fineness product with various textile fibers, usually blended with one or more fibers to form a spiral-wrapped thread structure. For some lightweight staple fibers such as cashmere, mink, acrylic, etc., although they have the characteristics of lightness, softness, slipperiness, and warmth, but due to their short length, small fineness, l...

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a three-dimensional lightweight fiber embedded composite yarn and its preparation method. By changing the traditional yarn structure and adopting a three-dimensional yarn structure design, it solves problems such as cashmere, mink, Due to the short length, small fineness, large dispersion and poor cohesion of acrylic and other light staple fibers, the spinnability is not ideal.
