Modified fiber product, preparation method and applications thereof

Abstract

The invention relates to a modified fiber product, a preparation method and applications thereof. The modified fiber product contains modified fiber, wherein the modified fiber contains graphene substances, graphene substances with the particle size of being less than 1mum are mainly inside the modified fiber, and the graphene substances with the particle size of being 1-20mum are mainly outside the modified fiber. By reasonably matching the distribution of graphene substances inside and outside the fiber, the distribution evenness of the graphene substances can be realized, especially the distribution evenness in longitudinal direction can be realized; by distributing different particle sizes of graphene inside and outside, the density of graphene can be increased, and the conductivity of the fiber can be improved; by adding biomass graphene, the far infrared function of the fiber can be enhanced, so as to enhance the microcirculation of a human body after wearing; and graphene substances are compounded inside and outside the fiber, especially at the crystallization area inside, the firmness of the graphene substances can be greatly increased, and the washability of the fiber can be improved.

Description

technical field [0001] The invention belongs to the field of fiber product preparation, specifically relates to a modified fiber product, a preparation method and its application, in particular to a conductive modified fiber product, a preparation method and its application. 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 pol...

AI Technical Summary

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, in the fiber products prepared by coating or simple impregnation process, the adhesion of graphene is not strong enough, and the additional function will be lost after repeated washing.
