Embodiment 1

[0041] First, on the continuous polyester equipment, according to the molar ratio of terephthalic acid (PTA), succinic acid (IPA), and ethylene glycol (EG) monomers in a ratio of 1:0.12:1.38, they are continuously and stably metered and Add it into the slurry kettle for beating, add zinc acetate and sulfamic acid in the beating kettle, wherein the molar ratio of the amount of zinc acetate to terephthalic acid is 0.03%, and the molar ratio of the amount of sulfamic acid to phthalic acid 0.05%;

[0042] Then, the above-mentioned slurry is continuously and stably transported to the esterification-I and esterification-II reactors, and a stabilizer is added in the esterification-II reactors to control the esterification rate to 98%, and the viscosity of the melt is controlled to be 0.66; The esterified product is pumped to the polycondensation section, and the modified polyester melt is prepared according to the polycondensation process at a temperature of 281-285° C., wherein the ...

Abstract

The invention relates to a succinic acid-modified terylene low-elasticity network fiber, which is prepared by the following steps of: preparing a succinic acid-modified terylene slice; performing a POY-DTY (Polyester Pre-Oriented Yarn-Draw Textured Yarn) circular blowing cooling process. The method can be finished on the conventional spinning equipment; and the fiber has the characteristics of tow yarn irregularity, uniform color distribution, flat texture and soft gloss and can be widely applied to the fields of clothing and decoration.

Description

technical field [0001] The invention relates to a synthetic fiber, in particular to a succinic acid modified polyester low-elastic network 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 output of polyester fiber has grown fro...
