Abstract
Description
Technical Field
[0001] This utility model relates to the field of covered yarn technology, specifically a low-elasticity cotton composite fiber covered yarn. Background Technology
[0002] Covered yarn, also known as wrapped yarn, is a new type of yarn with a core of filament or staple fiber wrapped around another type of filament or staple fiber yarn. The outer wrapping yarn wraps around the core yarn in a spiral pattern. Its characteristics include evenness, fullness, smoothness with minimal hairiness, high strength, and low breakage. Existing covered yarns are spun on hollow spindle spinning machines, where a layer of fiber material is wrapped around the core yarn. This type of covered yarn has a single function and limited applications.
[0003] Traditional covered yarns have certain limitations in terms of elasticity and feel. For example, some high-elasticity yarns are not soft and comfortable enough and lack the natural softness of cotton fibers; while cotton-based yarns are not elastic enough, are prone to deformation during wear and lack resilience, and cannot meet the requirements of some clothing styles that have high requirements for elasticity and shape retention.
[0004] To address this issue, we propose a low-elasticity cotton-like composite fiber-coated yarn. Utility Model Content
[0005] The purpose of this invention is to provide a low-elasticity cotton composite fiber covered yarn, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-elasticity cotton composite fiber covered yarn, comprising a yarn core, a covering yarn disposed on the outside of the yarn core, and an outer covering layer disposed on the outside of the covering yarn.
[0007] Preferably, the yarn core is made of multiple single low-elastic polyester fiber filaments wound together. The low-elastic polyester fiber has a certain elastic recovery, which can provide the yarn with moderate elasticity. At the same time, it has high strength, which is conducive to maintaining the overall structural stability of the yarn.
[0008] Preferably, the low-elastic polyester fiber filament has a linear density of 100D~150D, an initial modulus between 100~150cN / dtex, and a breaking elongation of 20%~30%. This specification of low-elastic polyester fiber can ensure that the yarn has a certain degree of elasticity without making the elasticity too high and affecting its low-elasticity characteristics.
[0009] Preferably, the covering yarn is made of multiple modified viscose fibers wound in the opposite direction to the winding direction of the yarn core. The modified viscose fibers have good softness and drape, and after special modification treatment, their strength and abrasion resistance are significantly improved.
[0010] Preferably, the outer covering layer is made of the same material as the yarn core.
[0011] This invention provides a low-elasticity cotton-like composite fiber covered yarn. This low-elasticity cotton-like composite fiber covered yarn has the following beneficial effects:
[0012] The covered yarn provided by this utility model has properties such as low elasticity, excellent cotton-like feel, good strength and abrasion resistance, while reducing production costs and improving production efficiency. Attached Figure Description

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0018] A preferred embodiment of the low-elasticity cotton composite fiber covered yarn provided by this utility model is as follows: Figures 1 to 3 As shown: A low-elasticity cotton-like composite fiber covered yarn includes a yarn core 1, which is formed by winding multiple single low-elasticity polyester fiber filaments. The low-elasticity polyester fiber has a certain degree of elastic recovery, which can provide moderate elasticity to the yarn. At the same time, it has high strength, which is conducive to maintaining the overall structural stability of the yarn. The linear density of the low-elasticity polyester fiber filaments is 100D~150D. The low-elasticity polyester fiber filament has an initial modulus between 100 and 150 cN / dtex and a breaking elongation of 20% to 30%. This specification of low-elasticity polyester fiber can ensure that the yarn has a certain degree of elasticity without making the elasticity too high and affecting its low-elasticity characteristics. The yarn core 1 is provided with a covering yarn 2, which is made of multiple modified viscose fibers wound in the opposite direction to the winding direction of the yarn core 1. The modified viscose fiber has good softness and drape, and after special modification treatment, its strength and abrasion resistance are significantly improved. The covering yarn 2 is provided with an outer covering layer 3, which is made of the same material as the yarn core 1.
