Abstract

The invention discloses a cotton-like polyester fiber. The cotton-like polyester fiber is prepared from 86.6-96wt% of hydrophilic polyester masterbatch, 1.0-5.0wt% of TiO2 masterbatch, 2.0-4.0wt% of amolecular weight regulator, 0.3-2.0wt% of an antioxidant, 0.5-1.5wt% of a lubricant and 0.2-0.9wt% of a wear-resistant agent. A spinning process is simple, and by adoption of the hydrophilic polyester masterbatch and the molecular weight regulator, the prepared cotton-like polyester fiber is quick in moisture absorption, delivery, diffusion and volatilization and capable of quickly absorbing moisture and sweat on the surface of skin and discharging to the outer layer; since part of body heat is taken away by high evaporation of sweat, the temperature drops, and a user can feel cool; the fiberhas great moisture absorption and water absorption performances and is excellent in hygroscopicity and liquid water hydroscopicity. The cotton-like polyester fiber is long in service life and high inwash fastness and has advantages of soft gloss in visual effect, novelty, fashionableness and easiness in caring.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a cotton-like polyester fiber and a production process thereof. Background technique [0002] With its excellent performance, polyester fiber has developed rapidly since industrialization. Polyester fiber has become the largest chemical fiber variety in my country. From January to December 2015, the cumulative production of chemical fiber in the country exceeded 35 million tons, of which polyester Fiber accounts for 79%, and polyester is widely used in clothing and home textiles. However, due to the regular arrangement of the molecular structure of conventional polyester fibers, the crystallinity is as high as 40% to 60%, and the macromolecules lack polar hydrophilic groups. The moisture regain of the fiber is only 0.4%, which makes the hygroscopicity of the fiber worse than that of natural fibers, which affects its comfort. At present, the research on improving the hygroscopic...
