Abstract

The invention relates to a manufacturing method of an antibacterial deodorizing polyester fiber, which comprises the following steps of: compounding zinc oxide whiskers with sterilizing and antibacterial functions, palygorskite fibers and various antibacterial agents with different antibacterial effects into a broad-spectrum antibacterial agent; preparing the broad-spectrum antibacterial agent and ethanediol into antibacterial ethanediol in the presence of a tiny amount of sodium hexametaphosphate; when polymerization esterification rate reaches 85%-90%, adding the antibacterial ethanediol to a polycondensation kettle, and polymerizing to prepare a copolyester antibacterial polyester, or blending and fusing the broad-spectrum antibacterial agent and the conventional polyester to prepare a blended antibacterial polyester; and fusing, compounding and spinning the antibacterial polyester as a shell layer and PET (Polyethylene Terephthalate) and PTT (polytrimethylene Terephthalate) serving as a core layer together to obtain the shell-core antibacterial deodorizing polyester fiber.

Description

technical field [0001] The invention relates to a method for manufacturing antibacterial and deodorizing polyester fibers. The antibacterial and deodorizing polyester fibers include zinc oxide whiskers, palygorskite fibers, silver-based antibacterial agents, and zeolite antibacterial agents, and belong to the technical field of textile fiber manufacturing . Background technique [0002] Polyester fiber is made of polyethylene terephthalate, and the trade name in China is polyester. It is the largest variety of synthetic fibers at present. Polyester fiber is an ideal textile raw material. Because of the high rigidity of the fiber macromolecular chain and high elastic modulus, the fiber is not easily deformed. Easy to wash and dry. It also has good heat resistance, sun resistance and abrasion resistance, and can be used at -70 to 170 °C. Polyester fiber has a wide range of uses in clothing, home textiles and industrial applications. But can not satisfy people's requirement...
