Embodiment 1

[0034] Preparation process of nano-modified slices:

[0035] First, on the continuous polyester equipment, use terephthalic acid (PTA) and ethylene glycol (EG) monomers to continuously and stably meter and feed them into the slurry tank according to the molar ratio of PTA and EG at a ratio of 1:1.25 In beating, add nano-tin dioxide, nano-manganese monoxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of nano-tin dioxide to terephthalic acid is 5.9%, and the addition of nano-manganese monoxide is the same as that of terephthalic acid. The mol ratio of phthalic acid is 1.3%, and the mol ratio of the addition of matting agent titanium dioxide and phthalic acid is 1.8%;

[0036] Then, the above-mentioned slurry is continuously and stably transported to the esterification-I and esterification-II reactors, and the stabilizer is continuously added to the esterification-II reactors at the same time to control the esterification rate of 98.0%, an...

Abstract

The invention relates to a preparation method of a nano-tin dioxide modified polyester fiber, and the preparation method comprises preparation of a nano-tin dioxide modified polyester chip, as well as spinning by a blending FDY (fully drawn yarn) process. The method can be completed on conventional spinning equipment, tow evenness is uniform, colors are distributed uniformly, and the obtained fabric is flat and has the characteristic of mild gloss. The nano-tin dioxide modified polyester fiber can be widely applied in the fields of clothes, decoration and industry.

Description

technical field [0001] The present invention relates to a kind of preparation method of synthetic fiber, specifically, the present invention relates to a kind of preparation method of nano tin dioxide modified polyester fiber. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material to weave various textiles due to their good drapability, high strength and crispness. With the globalization of the economy and the internationalization of the market, people's requirements for clothing are getting higher and higher. Not only must they be comfortable, but they must also be functional. There is a constant need to improve performance to meet weaving requirements. [0003] In the past ten years, my country's poly...
