Problems solved by technology

[0003] The traditional preparation methods of nano-zinc oxide composite textile fabrics include dipping method, coating method, magnetron sputtering method and spinning dope addition method, etc. Among them, the bonding fastness of the composite fabric is poor and uneven in the dipping method and coating method. and other problems, the service life of the composite fabric is greatly reduced
The cost of the magnetron sputtering method is relatively high, and it is not easy to promote and large-scale industrial production
The problem with the spinning dope addition method is that the addition of nano-zinc oxide materials increases the difficulty of spinning and the formation of fibers.
[0004] At present, most of the research focuses on supercritical fluid dyeing and conventional chemical preparation of nano-zinc oxide composite textile fabrics, and there is no report on the preparation of nano-zinc oxide composite textile fabrics using supercritical fluid technology.

Description

technical field [0001] The invention belongs to the field of multifunctional textile fabrics, and in particular relates to an anti-ultraviolet nano-zinc oxide composite textile fabric and a preparation method thereof. Background technique [0002] Nano-zinc oxide composite textile fabric refers to coating or wrapping nano-zinc oxide inside the fiber through physical and chemical means. Because nano-zinc oxide particles have unique surface effects, strong catalytic efficiency, macroscopic quantum tunneling effect and Small size effect, so it has special properties that ordinary zinc oxide does not have in terms of magnetism, electricity, light, heat, etc. At the same time, nano-zinc oxide has excellent physical and chemical properties in ultraviolet shielding, magnetic materials, and antibacterial disinfection. Has broad development prospects. [0003] The traditional preparation methods of nano-zinc oxide composite textile fabrics include dipping method, coating method, mag...
