Problems solved by technology

[0008] The current anion fibers are mainly post-processing and finishing. The post-finishing process is generally to disperse the anion powder in the liquid, and then attach it to the surface of the polyester fiber through a coupling agent. There are many defects in this product: the first is Poor durability and washing resistance; secondly, the downstream use of fibers is limited; finishing processing increases the uncertainty of the use of post-spinning auxiliaries

Abstract

The invention discloses a negative ion polyester fiber and a preparation method thereof. The negative ion polyester fiber is prepared from the following raw materials in parts by weight: 70-90 parts of polyester fiber chip and 10-30 parts of negative ion master batch, wherein the negative ion master batch is prepared from the following raw materials in parts by weight: 75-94 parts of polyester fiber chip, 5-34 parts of ultra-disperse negative ion powder, 0.5-5 parts of phthalic ester, 0.5-5 parts of pentaerythritol stearic acid ester, 0.05-1 part of tris-(2,4-ditertbutyl-pheny)-phosphite and 0.05-1 part of tetra [beta-(3,5-ditertbutyl-4-hydroxy phenyl) propionate] pentaerythritol ester. The negative ion polyester fiber disclosed by the invention has good usability, high spinnability and great advantages for the spinning of fine denier and the negative ion fiber with high occurrence quantity, and is high in occurrence quantity of negative ions and wide in application range; the preparation method of the negative ion polyester fiber is simple to operate and facilitates industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to an anion polyester fiber and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET), also known as polyester Polyethyeneterephthalate, is a polymer compound that is prepared by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). The technology of PET polyester spinning is known and common polyester fibers are abundantly available on the market. With the gradual improvement of living standards and the continuous deterioration of the natural environment, people have an increasingly strong desire for health, environmental protection and health care. It is under such conditions that the concept of negative ion health has begun to appear in the public's field of vision. [0003] Negative ions are called "air vitamins" in the medical field, and their main functions are as follows: [0004] 1. It affects the...
