Embodiment

[0018] Preparation of polybutylene succinate as degradable polyester

[0019] 1. The synthesis of polyester starts with catalyst solution configuration: the synthetic raw materials are butanediol and succinic acid, using titanium sulfate and tetrabutyl titanate as catalysts, first determine the amount of butanediol, and then add the catalyst to the catalyst configuration container, The amount of titanium sulfate added is 150×10 of the amount of butanediol -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.

[0020] 2. Then slurry configuration: add succinic acid into the slurry configuration tank according to the ratio of ...

Abstract

The invention relates to a fluorescent degradable polyester fiber which is characterized in that first, nano titanium dioxide, silver oxide, strontium aluminate and nickel powder are added into the synthesis of degradable polyester, and modified nano degradable polyester can be obtained; and the polyester is directly processed by melt spinning technique, so that the fluorescent degradable polyester fiber is obtained.

Description

technical field [0001] The invention relates to the field of fiber preparation, in particular to a fluorescent degradable polyester fiber. Background technique [0002] 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. The unique advantages of new fibers have created functional, comfortable and high-end textile fabrics. The new fiber has many advantages, and of course the added value created is also high. Compared with the general fiber, the new fiber is different, which is the value point. [0003] As one of the new fibers, environmentally friendly fibers are attracting people's attention, and new polybutylene succinate fibers have been developed continuously, which are applied to many fields such as medical, clothing, fishery, construction, sanitation, decoration, industrial processing, etc. . Among them, aliphatic polyesters that c...
