Example Embodiment

[0034] Example 1

[0035] Preparation process of modified polyester:

[0036] First of all, on the continuous polyester equipment, terephthalic acid (PTA) and ethylene glycol (EG) monomers are used, and the molar ratio of PTA to EG is 1:1.20, respectively, continuously and stably measured and added to the slurry tank In the middle beating, add nano zinc oxide, nano titanium dioxide, and matting agent titanium dioxide into the beating kettle. The molar ratio of nano zinc oxide to terephthalic acid is 1.65%, and the molar ratio of nano titanium dioxide to terephthalic acid 0.58%, the molar ratio of the added amount of matting agent titanium dioxide to phthalic acid is 0.20%;

[0037] Then, the above slurry was continuously and stably transported to the esterification-I and esterification-II reactors, and the stabilizer was continuously added to the esterification-II reactor at the same time to control the esterification rate of 98.5%; the esterification was pumped to the polycondensa...

Abstract

The invention relates to a method for preparing a modified polyester fully drawn yarn with ultraviolet resistance, which comprises the preparation step of condensing and polymerizing modified polyester melt and the preparation process of directly spinning the polyester fully drawn yarn (FDY). In the preparation process of condensing and polymerizing modified polyester melt, the modified co-polyester melt is prepared from pure terephthalic acid (PTA) and ethylene glycol (EG) monomers as raw materials by adding nano zinc oxide. The polyester melt is directly transported through a melt, extruded through metering and spinning assemblies, cooled by blowing air, oiled and wound by a channel, a first yarn guide roller and a second yarn guide roller to prepare the modified polyester fully drawn yarn. The prepared fiber has good ultraviolet resistance, and the reflecting ability to ultraviolet rays reaches as high as 50-60%. The prepared fiber has stable contraction rate, uniform dyeing and excellent spinning performance.

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 ...
