AI Technical Summary

Technical Problem

Existing light-absorbing and heat-generating fabrics are difficult to achieve antistatic effects, and the antistatic agent has weak bonding force with the fiber, resulting in a high rate of shedding after washing, which affects color fastness and durability.

Method used

By using CuS nanoparticles to coat silica, combined with disperse dyes, crosslinking agents, surfactants and adhesives, the silica-encapsulated copper sulfide nanoparticles are attached to the fabric through a pad dyeing process, forming a "core-shell" structure, thus achieving a combination of light absorption and heat generation with antistatic functions.

Benefits of technology

It achieves efficient photothermal conversion and electrical conductivity of the fabric, improves the antistatic level and the bonding strength between dye particles and fibers, reduces production costs, and has UV protection, making it suitable for everyday clothing and extreme outdoor scenarios.

Abstract

The application discloses a preparation method of a fabric with light-absorbing, heat-generating and antistatic composite functions. CuS nanoparticles are dispersed in a dispersion liquid, and tetraethyl orthosilicate is slowly added dropwise. After continuous stirring reaction, the reaction precipitate is dried to obtain silica-coated copper sulfide nanoparticles. The dispersion liquid is a mixed solution of ethanol, water and ammonia water. The silica-coated copper sulfide nanoparticles, disperse dye, crosslinking agent, surfactant, dispersant and deionized water are stirred and mixed, and ultrasonic dispersion is carried out. Then, the adhesive is added and stirred uniformly. Grinding particles are added to the mixed solution for grinding, and the grinding particles are removed through sieving to obtain a finishing liquid. The pretreated polyester fabric is pad-dyed in the finishing liquid, and is dried and solidified. Finally, the fabric product is obtained through washing and drying. The silica-coated copper sulfide nanoparticles realize the combination of light-absorbing, heat-generating, warm-keeping and static elimination functions, and the production cost is low, and the process is simple.
