Embodiment

[0022] 1. The synthesis of polyester is catalyst solution configuration at first: the present invention uses titanium sulfate and tetrabutyl titanate as catalyst, first determines the consumption of butanediol, then adds catalyst to the catalyst configuration container, and the addition amount of titanium sulfate is butanediol 100×10 of the amount of alcohol -6 , the amount of tetrabutyl titanate added is 300×10 of the amount of butanediol -6 , inject a small amount of butanediol, stir and heat to dissolve the catalyst in butanediol at 100°C, the dissolved butanediol catalyst solution enters the dilution container, and inject the remaining butanediol. After stirring, the content of the catalyst is measured to complete the configuration of the catalyst solution.

[0023] 2. Then slurry configuration: add succinic acid into the slurry configuration tank according to the ratio of alkyd to material ratio of 1.12, inject the catalyst solution, stir and mix to form a slurry, and tr...

Abstract

The invention relates to an antibacterial degradable polyester fibre. The invention is characterized in that firstly nano modified degradable polyester is obtained by adding 3-5% of nano silicon oxide and 3-6% of nano silver oxide in synthesis of polyester and then melt spinning is directly carried out, so as to obtain the antibacterial degradable polyester fibre.

Description

technical field [0001] The invention relates to the field of fiber preparation, in particular to an antibacterial and degradable polyester fiber. Background technique [0002] With the improvement of people's living standards, the requirements for textile fabrics are getting higher and higher. Today, with the rapid development of textile technology, fabrics made of various new fibers are being gradually applied to the development of textile fabrics by domestic textile enterprises. In fact, the unique advantages of new fibers have created functional, comfortable and high-grade textile fabrics. New fibers have many advantages, and of course the added value created is also high. Compared with ordinary fibers, new fibers are differentiated, which is the selling point. . [0003] Polybutylene succinate fiber, as one of the new fibers, is attracting people's attention, and new polybutylene succinate fibers are continuously developed, which are applied to medical, clothing, fisher...
