Functional rayon staple comprising nanopowder material

Abstract

A functional rayon staple containing nanoparticles is prepared from fiscose fibres (96-98 wt.%), natural tourmalinite nanoparticles under 100 nm (1.5-2.5 wt.%) and zinc oxide nanoparticles under 100 nm (0.5-1.5 wt.%) through mixing and jet spinning. Its advantages are health-care and regulation action on human body and organs, excellent infrared radiation, high resistance to ultraviolet ray, and generating negative ions.

Description

technical field [0001] The invention relates to an artificial fiber material with health-care and regulating effects on human skin and organs, in particular to a functional artificial cotton containing nanometer powder material. Background technique [0002] With the continuous development of science and technology, people are more concerned about the impact of textiles on consumers' bodies from the perspective of textile consumer ecology, which leads to the research on various functional man-made fiber materials. At present, the functional artificial fibers or their textiles that have been developed are mainly composed of viscose fibers containing industrial ceramic powder materials such as aluminum oxide, titanium dioxide, silicon dioxide, and zinc oxide. The functional textile and its manufacturing method provided by the invention patent specification, the medical non-woven fabric containing inorganic oxide composite powder provided by the Chinese inv...

AI Technical Summary

Problems solved by technology

The inorganic oxide composite powder of functional fibers and their textiles is contained in the main component of artificial viscose fiber. The diameter of artificial viscose fiber is generally tens of microns. If the inorganic oxide composite powder added If the particle size is greater than 500 nanometers, the strength of the fiber will be greatly reduced

At the same time, if the particle size of the inorganic oxide composite powder is too large, its specific surface area will also be reduced, that is, the area in contact with the outside world will be reduced, which will affect its negative ion release function.
