Abstract

The invention relates to a method for preparing a high-comfortable composite functional polyester fiber, comprising the steps of: first esterification reaction section, secondary esterification reaction section, polymerization reaction process and spinning process, wherein aliphatic dicarboxylic acid and / or non-centrosymmetrically aromatic dicarboxylic acid is led into the first esterification reaction section to serve as a third monomer; flexible polyethylene glycol is led into the secondary esterification reaction section to serve as a fourth monomer; after finishing the esterification reactions, hindered amine light stabilizer and hindered phenolic antioxidant which are respectively prepared by taking acetic acid and ethylene glycol as solvents and hydroxyl silicone oil are added; after finishing pre-polymerization and before final polymerization of the polymerization reaction process, ultraviolet light absorber and antistatic agent are added; and before finishing the spinning process, polyester slices are performed pre-crystallization and drying; fibers with odd-shaped cross sections of three-leaf, cross, five-leaf and the like are prepared by melt spinning. The obtained polyester fiber is anti-ultraviolet light, antistatic, anti-pilling and has wet-absorbing quick-drying performance; and the fabric has high comfort.

Description

technical field

[0001] The invention relates to a preparation method of a high-comfort composite functional polyester fiber. Background technique

[0002] The development of comfortable polyester fiber, after the rapid development of fine denier and ultra-fine denier in the chemical fiber industry, has become a key area of ​​development in the international and domestic industries in recent years. Since the international financial crisis in 2008, developed countries have accelerated the upgrading of textile technology In the footsteps of China, a variety of high-quality functional fiber fabrics have been put on the market in batches, and great progress has been made in the fine finishing and processing of natural fibers including cotton, wool, silk, and hemp. The quality and function of fabrics have achieved leapfrog upgrades. At the same time, the breakthrough of natural fiber pulp spinning technology has also brought a huge impact on the market of polyester chemical fiber ...
