Embodiment 1

[0035] Preparation process of modified polyester:

[0036] 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 to EG of 1:1.20 In beating, add nano silicon dioxide, nano copper oxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of nano silicon dioxide to terephthalic acid is 1.85%, and the nano copper oxide addition is the same as terephthalic acid. The mol ratio of formic acid is 0.50%, and the mol ratio of the addition of matting agent titanium dioxide and phthalic acid is 0.45%;

[0037] 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 98.5%; the esterification product is ...

Abstract

The invention relates to a method for preparing modified terylene fully drawn yarns (FDYs) with good abrasion resistance performance, which comprises a polycondensation modified polyester melt preparation step and a direct spinning terylene FDY preparation process, wherein in the polycondensation modified polyester melt preparation process, terephthalic acid (PTA) and ethylene glycol (EG) monomers are used as raw materials, in addition, nano silicon dioxide is added for preparation to obtain the modified copolyester melt, the modified copolyester melt is directly carried out melt conveying, and the modified terylene FDYs are prepared through metering, spinning assembly extrusion, air blowing cooling, oiling, course ways, a first yarn guide roller, a second yarn guide roller and coiling process. The modified terylene FDY fiber prepared by the method provided by the invention has good abrasion resistance performance and also has better reflecting capacity on ultraviolet rays, the prepared fiber has stable shrinkage rate, the dyeing is uniform, and the spinning performance is excellent.

Description

technical field [0001] The invention relates to a synthetic fiber, in particular to a modified polyester full-drawn yarn. 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 polyester industry has developed rapidly. The output of polyester fiber has grown from 5.165 million tons in ...
