ANTIBACTERIAL TEXTILE FIBRE MATERIAL AND METHOD OF OBTAINING IT Russian patent published in 2009 - IPC A61L2/16 

FIELD: textiles.

SUBSTANCE: present invention pertains to textile fibre material production, containing antibacterial substances. Antibacterial textile fibre material is based on cotton or lint or silk or wool, 97.9-99.7 wt % and partially soluble inorganic salts of silver - 0.3-2.5 wt %. Method of obtaining antibacterial textile fibre material consists of reduction of silver from an aqueous solution of silver nitrate with a reducing agent, in this case tannin and fixing the tanning agent on the fibrous material through soaking it in an aqueous solution of tartar emetic with a concentration of 0.5-1.5 wt %, separation from the aqueous phase, after which the moist fibrous material is put in an aqueous solution of silver nitrate of concentration 0.1-3.0 wt % heated to 50-100°C, separated from the aqueous phase and dry the obtained fibrous material with the silver applied on it followed by treatment with an aqueous solution of sodium hypochlorite or potassium dichromate.

EFFECT: invention makes it possible to increase in resistance to wet treatment of textile fibrous materials and expanding the colour range of antibacterial textile fibrous materials in towards light tones.
