Method for preparing fiber-grade polyester chip for textile processing

Abstract

The invention discloses a method for preparing a fiber-grade polyester chip for textile processing, and the method comprises the following steps: S1, preparation of antibacterial powder, namely a certain amount of zeolite with 400-800 ml of an antibacterial metal ion solution are reacted at 40DEG C for 2-4 hours; after the reaction is completed, centrifugal separation is carried out, and deionizedwater is used for washing until no antibacterial ion is separated out from a washing liquid; the obtained antibacterial ions are dried at 100 DEG C for 1 hour and then burned at 500 DEG C for 3 hoursto obtain the antibacterial powder. In the invention, high-temperature activated carbon powder and the antibacterial powder containing the antibacterial metal ions are added into the traditional rawmaterials of the polyester chip, and the antibacterial powder and the activated carbon powder have antibacterial and disinfecting effects, and are fully mixed and reacted with the polyester raw materials, so that the formed new polyester also has antibacterial and disinfecting effects, and further a textile fabric made of the polyester chip also has antibacterial and disinfecting effects.

Description

technical field [0001] The invention relates to the technical field of polyester chips, in particular to a method for fiber-grade polyester chips used in textile processing. Background technique [0002] Polyester is a general term for polymers obtained by polycondensation of polyols and polybasic acids. Generally, dibasic acids, dibasic alcohols and additives are adjusted into slurry to make finished polyester through direct esterification. The finished polyester mainly refers to poly Ethylene phthalate, which also customarily includes linear thermoplastic resins such as polybutylene terephthalate and polytrimethylene terephthalate, is one of the earliest materials used as textile raw materials, and it is also the mainstay of synthetic fibers. Number one variety. Its biggest advantage is that it has good wrinkle resistance and shape retention, and has high strength. It is durable, wrinkle-resistant, non-ironing, and non-sticky. Polyester chips have many excellent textile ...

Problems solved by technology

In the prior art, the textiles are generally soaked in the disinfectant and antibacterial agent after the textiles are made. Although this method can make the textiles have the characteristics of disinfection and antibacterial, the characteristics only exist on the surface of the textiles, resulting in many After the first use, the antibacterial and disinfection properties are easy to fade and disappear, and it cannot be stored for a long time, which is not conducive to the user's use
