Abstract

The invention relates to a preparation method of antibacterial conductive cotton fiber. Cotton fiber short fiber loose wool is used as a raw material. The method comprises the following steps that the cotton short fiber is deoiled, coarsened and subjected to sensitization pretreatment, a low concentration silver nitrate-ammonia water solution is added for activation, then chemical silvering is carried out, a chelating ligand agent is added during chemical silvering to replace some ammonia water, and high-temperature solidifying treatment is carried out after chemical silvering. The operation is simple, the technological performance is stable, energy consumption is small, and industrial production is easy. By the adoption of the antibacterial conductive cotton fiber, the plating layer combining firmness degree is high, the conductivity is good, the specific surface area resistance reaches 10-100 ohm / cm, the properties of common cotton fiber are reserved, and the cotton fiber can be used as the antibacterial and conductive cotton fiber, and can be made into antibacterial conductive cotton yarn after being matched with different proportions of common cotton short fiber to be used for various textiles.

Description

technical field [0001] The invention relates to a method for preparing antibacterial conductive cotton fibers. The method enables the substrate to have better electrical conductivity by plating a metal silver film on the surface of the substrate, and belongs to the field of new textile materials. Background technique [0002] Silver-plated fiber is a high-performance functional fiber. Its unique functions of antibacterial and deodorizing, anti-electromagnetic radiation, antistatic, and temperature regulation have attracted people's attention. There are three main types of fiber metal plating technology: chemical plating, electroplating and vacuum plating. The chemical silver plating process has the advantages of simple process, suitable for irregular substrate materials, and low cost. However, the current chemical silver plating process has difficulties in reaction, poor stability of the control bath, and expensive silver plating. The prepared conductive fibers The coating ...
