Abstract

The invention provides an antistatic, antibacterial and graphene-reinforced composite polyester fiber, which is characterized in that the composite polyester fiber comprises a component A and a component B, wherein the component A is polyester excluding graphene, and the component B is polyester including 0.3-3.0wt% of graphene. The invention also provides a preparation method of the composite polyester fiber. The composite polyester fiber provided by the invention is low in cost, high in strength, and high in antistatic and antibacterial properties.

Description

technical field [0001] The invention relates to the field of chemical fiber processing, in particular to a composite polyester fiber reinforced with graphene and a preparation method thereof. Background technique [0002] Due to its poor hygroscopicity, polyester fiber products tend to accumulate charges to form static electricity in dry climates, causing discomfort when wearing and using, and also restricting the application of polyester fibers in many fields, such as electronics and medical fields. . In order to improve its antistatic performance, it can be modified by adding conductive substances. The volume resistivity of general synthetic fibers is in the range of 10 15 Ω·cm or more, but to make the human body feel comfortable and not produce discharge phenomenon, the volume resistivity of the fiber should be 10 10 Ω·cm or less. With the improvement of people's requirements for the comfort of taking fibers, antistatic fibers combined with antibacterial properties ha...
