A composition for inhibiting the growth of microorganisms on non-cellulosic fibres having a moisture regain of & 5% comprising a self-cross linkable resin, a catalyst, an antimicrobial agent and water. Preferably, the non-cellulosic fibres are selected from polyester, polyamide, polypropylene, polyurethane and cellulose acetate. Preferably, the self-cross linkable resin is an amino resin, more preferably a formaldehyde condensate with urea or melamine, most preferably DMDHEU or DHDMEU. Preferably, the catalyst is selected from magnesium chloride, ammonium chloride, ammonium sulphate, ammonium salts of formic acid, boric acid, phosphoric acid, oxalic acid or most preferably poly(hexamethylene biguanide) hydrochloride. Preferably, the antimicrobial agent is selected from quaternary ammonium salts, biguanides and monoguanides. In another aspect, on non-cellulosic fibres carrying a composition comprising a self-cross linkable resin and an antimicrobial agent reacted with the resin. |
