Problems solved by technology

[0004] The disadvantage of this patented technical solution is that the edges of graphene particles have irregular geometric shapes and high hardness. The surface of graphene polyester fibers prepared by the blending method has a burr feeling due to the irregular geometric shapes of graphene particles, which affects its wearing comfort
However, grinding and ultrasonic dispersion can only solve the problem of graphene powder dispersion in polyester, but they cannot improve the wearing comfort of polyester fiber

Abstract

The invention relates to the field of polyester synthesis and discloses a catalyst-loaded graphene-modified polyester chip and a preperation method thereof. The polyester chip is prepared through esterification and polycondensation reaction of catalyst-loaded graphene powder, ethylene glycol and terephthalic acid. The prepared graphene-modified polyester chip is used for the production polyester fibers which are further processed into textiles. Consequently, the catalyst-loaded graphene-modified polyester chip has the advantages of enabling good comfort of the textiles, reducing processing costs, and having good anti-static and anti-ultraviolet effects.

Description

technical field [0001] The invention relates to the field of polyester synthesis, in particular to a catalyst-loaded graphene-modified polyester chip and a preparation method thereof. Background technique [0002] Graphene is often used as a functional phase and a reinforcing phase in composite materials due to its excellent properties. With the maturity of graphene preparation, chemical modification and dispersion technology, research on graphene-based polymer composites has progressed rapidly in recent years. At present, many domestic enterprises and research institutes are also actively exploring the application of graphene in the field of polyester chemical fiber, and have achieved some results. At present, there are many kinds of chemical fibers modified by graphene on the market, but the quality varies. [0003] Invention patent CN 104164707 A discloses a preparation method of graphene conductive polyester fiber with good conductivity and long-lasting antistatic. The...
