Embodiment

[0021] 1. The synthesis of polyester is catalyst solution configuration at first: the present invention uses p-toluenesulfonic acid and tetrabutyl titanate as catalyst, first determines the consumption of 1,2-propanediol, then adds catalyst to the catalyst configuration container, p-toluenesulfonic acid The amount added is 100×10 of the amount of 1,2-propanediol -6 , the amount of tetrabutyl titanate added is 300×10 of the amount of 1,2-propanediol -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 container, and inject the remaining 1,2-propanediol . After stirring, the content of the catalyst is measured to complete the configuration of the catalyst solution.

[0022] 2. Then the slurry configuration: add terephthalic acid into the slurry configuration tank according to the ratio of alkyd to material ratio of 1.12, inject the catalyst solution...

Abstract

The invention relates to an antistatic polyester fibre. The invention is characterized in that firstly nano modified poly (1, 2-propylene glycol terephthalate) is obtained by adding 3-5% of nano silicon oxide (SiO2) and 3-5% of nano zinc oxide (ZnO) in synthesis of polyester and then melt spinning is directly carried out, so as to obtain the antistatic polyester fibre.

Description

technical field [0001] The invention relates to the field of fiber preparation, in particular to an antistatic poly(1,2-trimethylene terephthalate) 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 selling point. [0003] Polypropylene terephthalate 1,2-trimethylene terephthalate polyester fiber, as a kind of new fiber, is attracting people's attention, and new modified polytrimethylene terephthalate polyester fiber is continuously developed. It can be synthesized by chemical process, and the industrialization prospect is promisin...
