Problems solved by technology

However, after the traditional pre-dyeing, dyeing, and post-finishing of bamboo fiber fabrics, their natural antibacterial properties have declined sharply.
Therefore, it is necessary to use antibacterial agents for treatment. Traditional antibacterial agents are mainly obtained through chemical synthesis. Not only the physical properties of the fabric undergo significant changes after treatment, but also the treated fabric has a certain stimulating effect on the skin. It will also gradually release harmful substances, which is not conducive to human health.

Abstract

The invention provides a preparation method of an antibacterial underwear fiber fabric. The antibacterial underwear fiber fabric is mainly prepared from 10-30% of bamboo fibers, 50-70% of cotton fibers, 10-20% of polyester fibers and 5-10% of nano silver ion fibers. All fiber materials are mixed evenly, a spinning melt is prepared, a natural antibacterial agent and natural plant mixed liquid are then added, the modified spinning melt is prepared, spinning fibers are obtained through melt spinning, then subjected to water washing, bleaching, oiling and drying and finally spun into the fabric, and the antibacterial underwear fiber fabric is obtained. The fiber fabric preparation technology adopts the ultra-low temperature crushing technology and the low temperature pressure-reducing drying technology. Effective components of the fabric can be mixed evenly, the antibacterial effect is good, the safety performance is high, the quality of the fabric is excellent, the application prospect iswide, and the fabric has good market value.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for preparing antibacterial underwear fiber fabrics. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for quality of life. Underwear is a necessary item for everyone, and the quality of its fabric affects people's lives. It is best to choose underwear made of natural fibers. Among them, cotton products are more suitable. It has good hygroscopicity and warmth retention, and the price is moderate. Synthetic fiber products generally have poor hygroscopicity, which is not conducive to the absorption and distribution of human sweat, and it is difficult to adjust the microclimate environment between the skin and underwear, so it often feels stuffy when worn next to the body. [0003] Bamboo itself has antibacterial properties, and there is no insects, no rot, and no need t...
