Embodiment

[0017] 1. The synthesis of polyester is first the catalyst solution configuration: the synthetic raw materials are 1,2-propanediol and terephthalic acid, using titanium sulfate and tetrabutyl titanate as catalysts, first determine the amount of 1,2-propanediol, and then put The catalyst is added to the catalyst configuration container, and the addition amount of titanium sulfate is 150×10 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.

[0018] 2. Then the slurry configuration: add terephthalic acid into the slurry configuration tank according to the ratio of a...

Abstract

The invention relates to nanometer pearl poly terephthalate 1, 2-trimethylene glycol ester polyester fiber which is characterized in that nanometer titanium dioxide, nanometer silver oxide, nanometer pearl powder and nanometer magnesium oxide are added in the process of synthesizing poly terephthalate 1, 2-trimethylene glycol ester polyester to obtain the nanometer modified poly terephthalate 1, 2-trimethylene glycol ester polyester, and the poly terephthalate 1, 2-trimethylene glycol ester polyester can be directly processed with the melt spinning process to obtain the nanometer pearl poly terephthalate 1, 2-trimethylene glycol ester polyester fiber.

Description

technical field [0001] The invention relates to the field of fiber preparation, in particular to a nano-pearl poly(trimethylene terephthalate) 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] Poly(1,2-trimethylene terephthalate) fiber, as one of the new fibers, is attracting people's attention. It can be synthesized by chemical process to continuously develop new products, which can be applied to the textile field and have industrialization prospects. However, polytrimethylene terephthalate polyester fiber also has it...
