METHOD OF THREAD PROCESSING Russian patent published in 2010 - IPC D02G3/44 B82B1/00 

FIELD: textile, paper.

SUBSTANCE: method includes thread impregnation with a collagen solution with antimicrobial substance and further drying. To impregnate the thread, a water nanosystem is used on the basis of collagen with nanodisperson of at least one bentonite powder, modified with cations Ag⁺ and/or Cu²⁺, with amount of these metals in the powder of 2.0-8.0 wt %, at the following ratio of components in nanosystem, wt %: collagen - 0.5-4.0, bentonite powder - 2-8.0, water - the rest. For impregnation, not more than 50 wt % of specified nanosystem is used per mass of dry thread. Dispersion of bentonite powder nanoparticles makes not more than 150 nm. A mixture of bentonite powder nanoparticles modified with ions Ag⁺ and Cu²⁺ with content of specified metals of 2-6 wt % in the mixture, at the ratio of powders of 1÷(0.3-0.5), accordingly. Deionised water is used to produce water nanosystem.

EFFECT: giving the thread prolonged antimicrobial properties in part of wide spectrum of gram-positive and gram-negative microorganisms, and adsorptive properties at simultaneous reduction of its toxicity and cost of technological process.
