Abstract
The invention discloses a preparation process and a method of a nano silver spunlace non-woven cloth composite antibacterial material, which mainly relate to the fields of nano antibacterial materials and spinning. Nano silver with different grain sizes is prepared through a liquid-phase chemical method, to obtain nano silver paste which is dispersed uniformly; the nano silver is uniformly dispersed into aqueous solution, to obtain nano silver dispersion liquid which has high efficiency, quick effect, broad-spectrum antimicrobial activity and different concentration is obtained; the dispersion liquid and PVP, adhesive FWT and the like which are in a certain ratio are compounded into modified nano silver dispersion liquid; and nano silver particles with the grain size of 10 to 30nm are firmly adhered on the surface of a spunlace non-woven cloth fiber, to form the nano silver spunlace non-woven cloth composite antibacterial material. The nano silver spunlace non-woven cloth composite antibacterial material prepared by the invention has quick effect and long effect in antibacterial performance, and spectrum antibacterial properties.
