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-silver oxide, nano-copper oxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of the addition of nano-silver oxide to terephthalic acid is 3.6%, and the addition of nano-copper oxide and terephthalic acid The mol ratio is 0.88%, and the mol ratio of the addition of matting agent titanium dioxide and phthalic acid is 2.5%;

[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 to 98.0%, and the viscosity of the melt is...

Abstract

The invention relates to a preparation method of nano silver oxide modified polyester fiber, which comprises a process of preparing nano silver oxide modified terelyene slices and a process of blending FDY for spinning. The method of the invention can be finished on the routine spinning equipment, the tow has the characteristics of dry and uniform strips, uniform color distribution, flat fabric, luster and softness, and can be widely used in the clothing field, the decoration field and the industry field.

Description

technical field [0001] The invention relates to a method for preparing a synthetic fiber, in particular to a method for preparing a nanometer silver oxide 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 polyester industry has developed rapidly. The outp...
