Problems solved by technology

[0007] If graphene is not modified and modified, the prepared graphene polyester fiber has poor antibacterial and deodorizing properties, but the modified graphene, due to the access of oxygen atoms, destroys the delocalized large π bond, As a result, the original high electron conductivity of graphene is lost, and the conductivity of graphene is greatly reduced.

Description

technical field [0001] The invention relates to a polyester fiber, in particular to a graphene polyester fiber with a deodorizing function and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. Polyester fiber is mainly made of polyethylene terephthalate. The trade name in China is polyester, or PET fiber for short. It is the largest variety of synthetic fiber at present. Its biggest advantage is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It's strong, durable, wrinkle-resistant and easy-care. [0003] Graphene has antibacterial properties, which can prevent the reproduction of bacteria and fundamentally avoid the generation of odor; graphene also has high conductivity and is the material with the lowest resistivity...
