Abstract

The invention relates to the field of chemical fiber. Aiming at the problem of poor dispersibility in the graphene-modified fiber process in the prior art, the invention discloses a preparation methodof a graphene-modified polyethylene terephthalate (PET) blend fiber. The preparation method of the graphene-modified PET blend fiber comprises the following preparation steps of (1) modifying graphene by using a cationic modifier; (2) preparing graphene-modified slices: blending the modified cationic graphene, a modifier and PET slice powder; (3) melting: melting PET slices and the graphene-modified slices; (4) blending: spraying two spinning melts from a composite spinneret so as to form the blend fiber; and (5) carrying out aftertreatment: cooling, oiling, stretching for setting and windingthe blend fiber. Through improving the dispersibility of a graphene slice layer, the uniformity of the graphene in the composite fiber is improved, the graphene-modified PET composite fiber with an excellent performance is obtained, and the fiber has a favorable mechanical property; and through spinning the graphene masterbatch slices and the PET slices through the composite spinneret, the four-leaf clover-shaped composite fiber is prepared.

Description

technical field

[0001] The invention relates to the field of chemical fibers, in particular to a method for preparing graphene-modified PET blended fibers. Background technique

[0002] Graphene is a new type of carbon material with excellent properties such as thermal conductivity, electrical conductivity, and good mechanical strength. It is praised by researchers at home and abroad as the most potential material in the 21st century. Because graphene has many outstanding properties, it is widely used in various fields such as chemistry, composite fibers, and catalyst carriers. my country is rich in graphite reserves, and has formed a series of comprehensive industries, such as mining, processing, and quality purification. Now my country's annual output of graphite has become the first in the world, about half of the world's total output, and the research and preparation process of graphene is also constantly developing, improving, and maturing. Therefore, graphene is used ...
