Warm-keeping antibacterial knitted underwear fabric and preparation method thereof

Abstract

The invention discloses warm-keeping antibacterial knitted underwear fabric and a preparation method thereof, and belongs to the technical field of knitted underwear fabric. The method comprises the following steps: blending high-shrinkage acrylic fibers and cotton fibers according to a blending ratio of (0.66-1.25):1 to obtain grey yarn, carrying out heat-moisture treatment to obtain bulked yarn,uniformly mixing a regenerated cellulose fiber solution with an antibacterial agent, and performing wet spinning to obtain antibacterial yarn, wherein the antibacterial agent is a silver ion antibacterial agent, spinneret orifices for wet spinning are trilobal, surface fabric comprises the following components in percentage by weight: 90%-95% of bulked yarn and 5%-10% of fine denier spandex; inner fabric comprises the following components in percentage by weight: 65%-80% of antibacterial yarn, 10%-25% of cotton fibers and 5%-10% of fine denier spandex; the surface fabric and the inner fabricare connected through elastic fibers; the obtained fabric is sequentially subjected to napping, velvet ironing and velvet shearing finishing to obtain the warm-keeping antibacterial knitted underwearfabric. The knitted fabric provided by the invention has multiple effects of pilling resistance, elasticity, antibiosis, warm keeping and the like.

Description

technical field [0001] The invention belongs to the technical field of knitted underwear fabrics, and in particular relates to an antibacterial and warm knitted underwear fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for dressing are getting higher and higher. Thermal clothing has developed from outerwear to underwear, and cold clothing has gradually developed from the traditional "warm, thick, heavy, and swollen" to "warm, light, thin, soft, and healthy". Today's thermal underwear is also developing from a single warm-keeping type to a comfortable, functional, healthy and warm-keeping type. Thermal underwear has become a new pillar product in my country's knitting industry. [0003] The warmth, elasticity and comfort of the fabric are the eternal themes of thermal underwear. As thermal underwear that emphasizes practical functions, no matter how it changes, it cannot be separ...

AI Technical Summary

Problems solved by technology

[0004] In terms of functionality, the existing underwear has a single function and generally only has the function of keeping warm

Existing thermal underwear is often made of cotton fibers and artificial synthetic fibers. The thermal insulation effect of cotton fibers is not ideal, and artificial synthetic fibers are likely to cause skin allergies, dryness, roughness, thickening, and even chapped, dermatitis, etc.

In addition, people wear more clothes in winter, and it is difficult to remove them in time after sweating, which leads to the breeding of bacteria in the inner layer of thermal underwear and affects human health.
