Embodiment 1

[0039] Preparation process of nanometer zinc oxide modified polyester:

[0040] 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-zinc oxide, nano-copper oxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of nano-zinc oxide to terephthalic acid is 1.85%, and the molar ratio of nano-copper oxide to terephthalic acid The molar ratio is 0.35%, and the molar ratio of the addition of matting agent titanium dioxide to phthalic acid is 0.35%;

[0041] 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, and the esterification rate is controlled to 98.5%, and the viscosity ...

Abstract

The invention relates to a method for preparing nanometer zinc oxide modified terylene low-elasticity network yarns, which comprises a polycondensation modified polyester melt preparation step and a polyester ortl yarn (POY)-draw textured yarn (DTY) circular air blowing cooling process, wherein in the polycondensation modified polyester melt preparation process, the terephthalic acid (PTA) and ethylene glycol (EG) monomers are used as raw materials, in addition, nanometer zinc oxide modifier is added for preparation to obtain the modified copolyester melt, the modified copolyester melt is directly carried out melt conveying to prepare the modified terylene low-elasticity network yarn through the POY-DTY circular air blowing cooling process. The fiber prepared by the method disclosed by the invention has a good ultraviolet ray prevention function, the reflecting capacity on ultraviolet rays is as high as 50 percent to 60 percent, in addition, 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 low-elastic network 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...
