Problems solved by technology

[0004] Chinese invention patent CN00800536.2 adds magnesium aluminum hydrotalcite to the antibacterial composition, which can inhibit the discoloration of plastic products containing silver-based antibacterial agents. Hydrotalcite is cheap, but its effect in textiles is unknown
Chinese invention patent CN2005100109965 provides an anti-discoloration inorganic antibacterial agent. First, the silver-zinc mixed solution is dispersed in the silica gel solution, and then sintered to make the silver ions embedded in the crystal lattice, thereby reducing the precipitation and oxidation of silver and improving the discoloration. , has good antibacterial and anti-discoloration effects, but the preparation process is more complicated
In summary, there is currently a lack of an antibacterial agent with excellent performance or a simple process to make nylon fibers have antibacterial properties and good discoloration resistance.

Abstract

The invention relates to a color-change-resistant anti-bacterial polyamide fiber, which is mainly prepared from polyamide and antibacterial masterbatch according to a weight ratio of 100:(1 to 10), wherein the antibacterial masterbatch is prepared from the following raw materials in parts by weight: 70 to 95 percent of long-carbon-chain nylon and 5 to 30 percent of silver carried ion antibacterialagents; the color-change-resistant anti-bacterial polyamide fiber also contains at least one kind of materials in dispersing agents, antioxidants and light stabilizing agents. The prepared color-change-resistant anti-bacterial polyamide fiber hardly generates color change in the processing and use process; the excellent color-change-resistant performance is realized; in addition, the anti-bacterial performance is stable and durable.

Description

technical field [0001] The invention belongs to the field of antibacterial fiber preparation, and in particular relates to a discoloration-resistant and antibacterial nylon fiber. Background technique [0002] With the increase of people's attention to health, the antibacterial function of textiles is also required, and the antibacterial effect of textiles is mainly realized by antibacterial fibers. Antibacterial fibers have antibacterial and bactericidal functions, which can prevent infection and infection, and are widely used in home textiles, underwear, sweatshirts, etc., especially clothing for the elderly, pregnant women and infants. Clothes made of this fiber have good antibacterial properties and can resist the adhesion of bacteria on clothing, thereby keeping people away from the invasion of germs. The antibacterial fiber's resistance and killing effect on bacteria is not a one-time temporary effect, but a long-term effect of several weeks to years. The reason why ...
