Problems solved by technology

The above methods are all made of antibacterial masterbatch first, and then mixed with polyester resin. First, the process route is complicated and the efficiency is low. In addition, it is difficult to spin fine denier yarns, especially when nano silver is used as an antibacterial agent.
The disadvantages of the use of nano-silver are that it is expensive, easy to change color, and the precipitation of silver ions produces pigmentation. The effect on Candida albicans is weak. In addition, silver ions are easy to cause adverse effects on the environment and human health.

Abstract

The invention provides a rapid preparation method and an application of antibacterial and deodorant polyester yarn. The technical scheme is that the method comprises the following steps: various soluble metal salts and a polymer complexing dispersing agent are dissolved in water, and an aqueous solution is prepared; the aqueous solution is added to ethylene glycol under intense stirring, and a water-in-oil system is formed; a reaction is performed in a microwave oven at 140-170 DEG C for 15-60 min, ultrasonication is performed for 20-40 min, and a multi-component nano metal oxide self-assembled dispersion is obtained; free water in the nano metal oxide self-assembled dispersion is evaporated and concentrated in a vacuum state, and water content is controlled at 0.5%-1%. In the polymerization spinning process of polyester, the nano metal oxide self-assembled dispersion is injected in the mass ratio of 2%-10% of the total quantity of a chemical fiber polymer, and the antibacterial and deodorant polyester yarn and polyester staple fibers are obtained through esterification, polycondensation, spinning, cooling and forming. The process for the antibacterial and deodorant polyester yarnis simple, high in efficiency, energy-saving and environmentally friendly; the product has efficient and lasting antibacterial and deodorant functions, is free of metal ion release and is quite safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of preparation of special textile materials, in particular to a rapid preparation method and application of antibacterial and deodorizing polyester yarn.
