High-hygroscopicity yarn and preparation method thereof

Abstract

The invention discloses a high hygroscopicity yarn and a preparation method thereof. The high hygroscopicity yarn is provided with a core yarn, a core-spun layer and a surface layer, the core yarn is formed by spirally twisting regenerated soybean protein fibers, water-soluble vinylon short fibers and high hygroscopicity fibers; the core-spun layer is formed by twisting polynosic yarn and forming the polynosic yarn on the outer surface of the core yarn; and the surface layer is formed by twisting skin-friendly fibers and is formed on the outer surface of the core-spun layer. During preparation, the soybean protein fibers are pretreated to form regenerated soybean protein fibers with space gaps inside, and then the regenerated soybean protein fibers, the water-soluble vinylon short fibers and the high-moisture-absorption fibers are spirally twisted to form the yarn, the yarns are subjected to vinylon removal treatment to remove water-soluble vinylon short fibers in the yarns to form space gaps among the yarns, and the space gaps are used for improving the yarns and filling the yarns with antibacterial materials. The yarn has better moisture absorption, air permeability, bacteriostasis and heat preservation effects, and the wearing comfort of a fabric woven by using the yarn can be effectively improved.

Description

technical field [0001] The invention relates to yarn processing technology in the field of textile technology, in particular to a highly hygroscopic yarn and a preparation method thereof. Background technique [0002] Yarn is a soft and slender fiber aggregate with certain mechanical properties formed by the aggregation of various textile fibers along the length direction. It is also the most important and basic material for fabric production. It can be widely used in weaving and rope making. , thread making, knitting, embroidery and other textile operations, and with the advancement of textile technology and the improvement of people's pursuit of quality of life, people's needs for various daily necessities are becoming more and more diverse, and the requirements for fabrics are not only Limited to comfort, but also hope that the fabric or fiber has some functionality. [0003] In recent years, people have higher and higher requirements for the comfort, health, safety and ...

Problems solved by technology

[0003] In recent years, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. As people spend more time outdoors, the market demand for sports towels and personal sportswear is getting higher and higher. , the fabrics used to make sports towels and close-fitting sportswear require not only good comfort, but also good hygroscopicity, air permeability and thermal insulation. In the prior art, cotton fiber yarns of a single material are mostly used As a raw material for weaving, bamboo fiber yarns have also appeared in recent years, but whether it is cotton fiber yarns or bamboo fiber yarns, the hygroscopicity of the yarn itself is not satisfactory, and after absorbing moisture, the fibers swell laterally after a large amount of moisture absorption, while The gaps between the yarns are closed, resulting in slow moisture distribution, the inhaled moisture cannot be diffused outward, the moisture distribution is slow, and it is very easy to breed bacteria in a warm environment or not dried in time or air-dried
