Abstract

The invention relates to a post treatment method of a fiber product. The post treatment method of the fiber product comprises the following steps: (A1) impregnating the fiber product with first graphene type substance dispersion, taking out, then heating to the high-elastic state temperature of a fiber material, and carrying out primary compound treatment at a constant post-treatment temperature, wherein the particle size of graphene type substances in the first graphene type substance dispersion is less than 1mu m; and (A2) impregnating the fiber product subjected to the primary compound treatment into second graphene type substance dispersion, taking out, then heating to a second post treatment temperature, carrying out secondary compound treatment at a constant temperature, then cooling, and drying, so that a composite fiber product is obtained, wherein the particle size of graphene type substances in the second graphene type substance dispersion is 1-20mu m. The post treatment method provided by the invention has the advantages that adhesion firmness of the graphene type substances on fibers is improved; meanwhile, from the viewpoint of radial direction of the fibers, more graphene type substances with small particle size are distributed inside, and distribution uniformity of the graphene type substances in the radial direction of the fibers is improved.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and in particular relates to a post-treatment method of fiber products, the obtained modified fiber products and uses thereof. Background technique [0002] The development of conductive fibers began in the 1960s. Conductive fibers usually refer to those with a specific resistance lower than 10 in a standard environment (temperature 20°C, humidity 65%). 7 Ω·cm. Its development process roughly includes four 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 been greatly developed, there are still certain problems, such as fabrics made of metal conductive fibers and metal-plated conductive fibers, which have rough hand feeling and poor comfort, and the conductive polymer process is complicated and serious pollution. Furthermore, the ...
