Embodiment 1

[0030] This embodiment provides a method for preparing an antistatic, anti-pilling, normal-pressure cationic dyeable polyester chip, which includes the following steps:

[0031] (1) One-time esterification reaction process: Take 18kg of purified terephthalic acid (PTA) and 7.05kg of ethylene glycol (EG), add 70 liters of polyester experimental equipment, stir evenly, start to heat up and pressurize to 0.3Mpa , carry out esterification, the esterification temperature is controlled at 255 ~ 260 ° C, until the esterification water is completed, return to normal pressure, and end the reaction.

[0032] (2) Transesterification reaction process: After the primary esterification is completed, add ethylene glycol to cool down and depolymerize, control the temperature at 220-245°C for 0.4-1.0 hours, then add 1400g of three-monomer solution, stir evenly, and heat up to At 255°C, the transesterification reaction is carried out, so that the unreacted SIPM can complete the transester...

Abstract

The invention relates to a preparation method of an antistatic, anti-balling, and ordinary pressure cation dyeable polyester chip, comprising the following steps: a primary esterification reaction step, an ester exchange reaction step, a secondary esterification reaction step, and a polymerization reaction step, wherein, a ternary-monomer is added in the ester exchange reaction step, hindered anime light stabilizers, hindered phenol antioxygens and hydroxyl silicone oil are added after the ester exchange reaction and before a prepolymerization reaction, and an antistatic agent is added after the prepolymerization of the polymerization reaction step and before a final polymerization. Fabrics prepared from polyester fibers produced by using the polyester chips disclosed herein have good antistatic behavior and good anti-balling behavior, and have unlimited dyeing possibilities by using the ordinary pressure cation dyeability, thus the uniform requirements of present high-grade spring and summer clothes for functionality and colors can be satisfied. The obtained fibers can be dyed with wool together, and the blending of the fibers with wool has good dress effect. The polyester chips and fibers disclosed herein are an important supplement of present cation dyeable polyester fiber market, and have a wide market prospect.

Description

technical field [0001] The invention relates to a preparation method of a polyester chip, in particular to a preparation method of an antistatic, anti-pilling, normal-pressure cationic dyeable polyester chip. Background technique [0002] In recent years, with the rapid development of domestic polymerization technology, my country's functional polyester synthesis technology has made great progress. Domestic cationic dyeable polyester has formed a scale of nearly 400,000 tons, and its differentiated varieties emerge in endlessly. There is a momentum of booming production and sales, but we should also see that there is a considerable gap between my country's cationic polyester synthesis technology and application range and developed countries. The main application fields of my country's cationic dyeable polyester fibers are decorative fabrics and fabrics. Garment moldings, which have a great distance from the original intention of the development of cationic dyeable polyeste...
