Embodiment 1

[0038] Preparation process of nanometer zinc oxide modified polyester:

[0039] 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 modifier, nano-titanium dioxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of nano-zinc oxide to terephthalic acid is 1.75%, and the addition of nano-titanium dioxide to terephthalic acid The mol ratio is 0.35%, and the mol ratio of the addition of matting agent titanium dioxide to phthalic acid is 0.12%;

[0040] Then, the above-mentioned slurry is continuously and stably transported to the esterification-I and esterification-II reaction kettles, and a stabilizer is added to the esterification-II reaction kettles to control the esterification rate to 98%, and the viscosity to be controlled...

Abstract

The invention relates to a method for preparing a nano-ZnO (zinc oxide) modified polyester pre-oriented yarn. The method comprises preparation of modified polyester melt and preparation of direct-spun polyester pre-oriented yarn (POY); and in the process of preparing a modified polyester melt, a pure terephthalic acid (PTA) and an ethylene glycol (EG) monomer are taken as raw materials, and a nano modifier is added so as to prepare a modified copolyester melt, then the polyester melt is directly conveyed by a melt, and through carrying out metering, spinning assembly extrusion, air blast cooling, oil applying, channel passing, and winding on the polyester melt, a nano-ZnO modified polyester pre-oriented yarn is obtained. A fiber prepared by using the method provided by the invention has a good ultraviolet-resistant function, and the ultraviolet reflection capacity of the fiber is as high as 50-60%.

Description

technical field [0001] The invention relates to a synthetic fiber, in particular to a modified polyester pre-oriented 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 i...
