Abstract

The invention belongs to the field of fiber materials, in particular to a far-infrared fiber for a physiotherapy travel mat and a preparation method of the far-infrared fiber. The preparation method of the far-infrared fiber for the physiotherapy travel mat comprises the following steps: S1 deacetylation of chitosan; S2 preparation of quaternary ammonium salt modified chitosan; S3 preparation of a spinning stock solution; S4 preparation of a nanometer powder dispersion; S5 preparation of a spinnable solution; S6 wet spinning. The far infrared fiber prepared with the method has better far infrared performance, antibacterial property, washing resistance and high durability, is comfortable, insulated, environmentally friendly and safe, and has effects of refreshing the mind, diminishing inflammation, promoting wound healing and effectively relieving human fatigue.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to a far-infrared fiber used for a physiotherapy travel pad and a preparation method thereof. Background technique [0002] The physiotherapy travel pad includes a travel pad body, a battery slot, a graphene heating layer, and wires. The travel pad body contains a far-infrared emitting layer, and the wires are connected to the far-infrared emitting layer and the graphene heating layer, which makes cleaning difficult. However, if it is used for a long time without cleaning, the dander produced by the human body will adhere to the physiotherapy mat, which will easily lead to the breeding of bacteria and mites, which is not good for the human body, and will lead to a decrease in far-infrared performance and a shorter service life. At present, antibacterial far-infrared fibers are generally prepared by adding antibacterial agents and far-infrared powders, but their antibacteri...
