[0019] Example

[0020] 1. The synthesis of polyester first is the catalyst solution configuration: the present invention uses titanium sulfate and tetrabutyl titanate as the catalyst, first determines the amount of 1,2-propanediol, and then adds the catalyst to the catalyst configuration container. The addition amount of titanium sulfate is 1,2-propanediol amount 100×10 -6 , Tetrabutyl titanate addition amount is 300×10 of 1,2-propanediol amount -6 , Inject a small amount of 1,2-propanediol, stir and heat to dissolve the catalyst in 1,2-propanediol at 100°C, the dissolved 1,2-propanediol catalyst solution enters the dilution vessel, and inject the remaining 1,2-propanediol . After stirring, the content of the catalyst is measured to complete the configuration of the catalyst solution.

[0021] 2. Then the slurry configuration: add terephthalic acid to the slurry configuration tank according to the ratio of alkyd material to 1.13, inject the catalyst solution, stir and mix into sl...

Abstract

An anti-bacterial poly terephthalic acid 1, 2-propylene glycol ester fiber is characterized in that a nano-modified poly terephthalic acid 1, 2-propylene glycol ester is firstly obtained by adding 3-5percent of nanometer titanium dioxide and 3-6 percent of silver oxide in the synthesis of a polyester, and then the anti-bacterial poly terephthalic acid 1, 2-propylene glycol ester fiber can be directly obtained by a melt spinning process from the polyester.

Description

technical field [0001] The invention relates to the field of fiber preparation, in particular to an antibacterial poly(1,2-trimethylene terephthalate) 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. . Polypropylene terephthalate fiber, as one of the new fibers, is attracting people's attention, and new polypropylene terephthalate fiber is continuously developed, which is applied to medical, food, ...
