Abstract

The invention relates to the field of fiber processing, and especially relates to a graphene polymer fiber and a preparation method thereof. The preparation method of the graphene polymer fiber comprises the following steps: spinning a graphene mixture and polymer resin mixture used as a core layer and a water-soluble polyester slice used as a skin layer to obtain a double-component composite fiber; and removing the surface water-soluble polyester from the double-component composite fiber to obtain the graphene polymer fiber. The graphene mixture and polymer resin mixture used as the core layer and the water-soluble polyester slice used as the skin layer are spun, and the skin layer is removed through a water dissolving treatment technology to prepare the high-profile degree conductive graphene fiber. The method is simple and is easy to implement; the prepared fiber has high profile degree, and has an enhanced siphon effect on sweat; and a fabric made of the fiber has the characteristics of soft, comfortable, dry and clean hand feeling, high electric conductivity, good antibiosis and bacteriostasis property, and good moisture absorption and sweat perspiration property. The fabric made of the fiber realizes multifunctional compounding of single fibers, and greatly increases the added values of products.

Description

Technical field [0001] The invention relates to the field of fiber processing, in particular to a graphene polymer fiber and a preparation method thereof. Background technique [0002] Conductive fiber usually means that the resistivity is less than 10 in the standard state (20℃, 65% relative humidity) 7 Ω·cm fiber, this fiber has good conductivity and durability, especially in low humidity, widely used in industrial and civilian fields. The antistatic mechanism of conductive fibers is to generate corona discharge between the fibers. When the static voltage reaches a certain value, a spark-free corona discharge is generated to eliminate static electricity. At present, antistatic fabrics mostly use composite spinning technology to add conductive substances to the fibers, so that the fibers have both excellent processing performance and electrical conductivity. [0003] Graphene is a two-dimensional sheet material composed of a single carbon atom in thickness. The special layer str...
