Process for the treatment of fibres e.g. of nylon or polyester/cotton in which the fibres are contacted with a polydiorganosiloxane having at least one -OM group, in which M represents H, alkyl or alkoxyalkyl, and at least one quaternary ammonium salt substituent -RN<+> (R sec )2R min X<-> in which R represents a divalent hydrocarbon or hydrocarbonoxy group, R min represents a monovalent hydrocarbon group or an alkyleneoxy or polyalkyleneoxy group, each R sec represents methyl or ethyl and X represents a halogen atom. The treatment facilitates the removal of oily stains during laundering and may be applied in conjunction with other silicones. |
