Problems solved by technology

Although the conductive fiber has been greatly developed, there are still some problems, such as the fabric made of metal conductive fiber and metal-plated conductive fiber feels rough, poor comfort, conductive polymer process is more complicated, and the pollution is serious
Furthermore, the composite firmness of graphene fiber products produced by coating or simple impregnation process is not strong enough, and the additional functions will be lost after washing many times.

Abstract

The invention discloses a modified polyester fiber production method. Graphene sheet layers exist inside and outside polyester fiber of a modified polyester fiber product; the polyester fiber productcomprises polyester fiber, polyester yarn and polyester fabric. Graphene is attached or added to the inside and outside of the polyester fiber and the uniformity and firmness of graphene are improved.The conductivity of the polyester fiber is improved by adding graphene and / or biomass graphene. The far infrared performance of the polyester fiber is further reinforced by adding graphene oxide and / or biomass graphene. With the adoption of the production method, the graphene can be effectively added to the inside of the polyester fiber, meanwhile, the outside of the polyester fiber is coated with the graphene sheet layer, and graphene can be uniformly distributed on the polyester fiber by impregnating the polyester fiber product with a graphene solution.

Description

Technical field [0001] The invention belongs to the field of fiber product production, and specifically relates to a method for producing modified polyester fibers. Background technique [0002] The development of conductive fiber began in the 1960s. Conductive fiber usually means that under a standard environment (temperature 20°C, humidity 65%), the specific resistance is lower than 107Ω·cm. Its development process roughly includes 4 stages: metal fiber, carbon fiber and composite conductive fiber containing carbon black composite polymer, conductive fiber containing metal salt, conductive polymer conductive fiber. Although conductive fibers have made considerable progress, there are still certain problems. For example, fabrics made of metal conductive fibers and metal-plated conductive fibers have rough hand feel, poor comfort, conductive polymer technology, and serious pollution. Furthermore, the fiber product graphene produced by coating or a simple dipping process is not s...
