Problems solved by technology

However, although the existing polyester fiber itself has excellent mechanical properties, its antibacterial properties are relatively poor, and it cannot effectively inhibit the reproduction of microorganisms.
The reproduction of microorganisms is not only detrimental to the health of the wearer, but also causes damage to the polyester fiber fabric to a certain extent, thereby shortening the life of the fabric.

Abstract

The invention relates to the technical field of fiber material preparation, in particular to an antibacterial fiber material and a preparation process thereof. The antibacterial fiber material is prepared from the following raw materials in parts by weight: 100-120 parts of PET polyester chips and 3-6 parts of antibacterial master batch, wherein the antibacterial master batch is composed of a proper amount of PET polyester chips, and 6-10% by mass of an antibacterial agent, 0.3-0.8% by mass of an ultraviolet absorbent, 0.2-0.6% by mass of an antistatic agent, 0.6-1.8% by mass of zinc stearate, 1.5-3.6% by mass of sodium hypophosphite, and 2.8-4.2% by mass of 3-hydroxy-1,3,5-valeric acid based on the mass of the PET polyester chips. The fiber material prepared by the preparation method disclosed by the invention not only has excellent antibacterial performance, but also is relatively long in antibacterial time; the effects of slow release and long-acting sterilization are achieved, and the antibacterial performance and quality of the prepared antibacterial fiber material are guaranteed; the antibacterial agent used in the invention has the advantages of small toxicity, small irritation to human bodies and high safety; in addition, the fiber material also has certain ultraviolet resistance and antistatic property, and is comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of fiber material preparation, in particular to an antibacterial fiber material and a preparation process thereof. Background technique [0002] Fiber is the basic unit of textiles, which determines the functional properties of textiles. Fiber is a substance composed of continuous or discontinuous filaments, and is widely used in many fields such as textiles, military affairs, environmental protection, medicine, construction, and biology. There are two types of fibers: natural fibers and chemical fibers. Natural fibers exist naturally and are divided into plant fibers, animal fibers and mineral fibers; while chemical fibers are processed through chemical treatment and can be divided into man-made fibers, synthetic fibers and inorganic fibers. [0003] Polyester has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent set properties...
