METHOD FOR PRODUCTION OF ANTIMICROBIAL SILVER-CONTAINING FIBRE BASED ON NATURAL POLYMER Russian patent published in 2010 - IPC D06M11/01 D06M11/65 D06M101/12

Abstract RU 2402655 C2

FIELD: textile, paper.

SUBSTANCE: method for production of specified material includes impregnation of natural polymer with aqueous solution of silver nitrate. Natural polymer is represented by natural silk fibroin, which is treated for 20-60 min by aqueous solution of silver nitrate with concentration of 0.025-1.0 wt % at room temperature. Moreover, sodium borohydride is added to solution at the ratio of silver nitrate: sodium borohydride 1:1 - 1:10. Material impregnation is carried out at bath module of 1:10 - 1:25.

EFFECT: invention makes it possible to use material such as fibre, woven, nonwoven or jersey fabric.
