Blended yarn product of copper modified polyester fibers and bamboo fibers and spinning method

Abstract

The invention discloses a blended yarn product of copper modified polyester fibers and bamboo fibers and a spinning method of the blended yarn product. The blended yarn product comprises 38%-43% of the copper modified polyester fibers and the balance bamboo fibers. Premixing is conducted on the copper modified polyester fibers and the bamboo fibers, and the blended yarn product is obtained through a sliver blending method in a multi-step blending mode. According to the indexes of the spun yarn, the CVm is 12.60%, H is 3.0, snicks below 50 account for 5%, slugs above 50 account for 15%, neps above 200 account for 18%, the strength is 260 CN, and the nip gauge is 2.25 mm. According to the blended yarn product of the copper modified polyester fibers and the bamboo fibers and the spinning method of the blended yarn product, 38%-43% of the copper modified polyester fibers and the bamboo fibers are blended to obtain the blended yarn product, the advantages that the bamboo fibers are smooth, overhanging and naturally antimicrobial and have the excellent moisture absorption and desorption property stand out, and the defects that the bamboo fibers are low in strength and poor in abrasive resistance are overcome; fabric of the blended yarn product has the advantages of being smooth, stiff, unrestrained, good in conformality, hygroscopic, breathable, resistant to ultraviolet rays, antibacterial and bacteriostatic, deodorant, healthy, sanitarian and the like; noble and elegant demeanor is absolutely shown.

Description

Technical field [0001] The invention relates to spinning technology, specifically a blended yarn of copper modified polyester fiber and bamboo fiber and a spinning method. Background technique [0002] With the advancement of human science and technology, population growth, and the continuous improvement of people's consumption levels, the demand and requirements for clothing are also developing to higher levels and requirements. In terms of textiles, it is not only required to keep warm, but also to pursue new and emerging functions such as novelty, ecology, fashion, high-end, function, environmental protection, and health. Copper modified polyester fiber / bamboo fiber blended yarn is made by blending a certain proportion of bamboo raw fiber and a certain proportion of copper modified polyester fiber. Both are primary color fibers, no dyeing, energy saving, environmental protection, and pollution-free. And both are functional fibers, which can complement each other in spinnabili...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the bamboo fiber is white with a slight yellow color, and the copper-modified polyester fiber is light brown, the two do not need to be dyed into primary color yarn after blending, but the appearance color difference between the two is too large, the mixing is uneven, and the proportion is not appropriate. There will be flowery yarns, and the fabric flowers will affect the appearance

[0007] 2. Due to poor cohesion of bamboo fiber, brittle fiber and low strength, copper modified polyester fiber has high strength, wear resistance and soft hand feeling, but the cost is high. The two can only complement each other by blending, but the direct blending ratio of the two can be Reach the need to reduce costs and meet the quality requirements of users in all aspects

[0008] 3. For single yarn ring spinning, due to the special drafting parts in each process and the accidental drafting of the process, the spinning product has poor evenness and more hairiness
