Abstract
Abstract PCT No. PCT/AU85/00297 Sec. 371 Date Aug. 7, 1986 Sec. 102(e) Date Aug. 7, 1986 PCT Filed Nov. 29, 1985 PCT Pub. No. WO86/03528 PCT Pub. Date Jun. 19, 1986.A method for protecting proteinaceous fibres, either dyed or in their natural form, against photodegradation and thermal degradation. The method comprises treating the fibres with a sulfonated s-triazine derivative of formula (I), wherein R1 is hydrogen, alkyl, hydroxyl, O-alky, OOC-alkyl or OOCNH-alkyl; R2 is hydrogen, alkyl or SO3X; R3 is aryl, substituted aryl or O-alkyl; and X is hydrogen, NH4 or alkali metal, or formula (II), wherein R1 and R4 are hydrogen, alkyl, hydroxyl, O-alkyl, OCC-alkyl or OOCNH-alkyl; R2 and R5 are hydrogen, alkyl or -SO3X; R3 is hydrogen or -SO3X; R6 is aryl, substituted aryl, O-alkyl or O-aryl; and X is hydrogen, NH4 or alkali metal; under acidic conditions. The method is particularly suitable for treating dyed and undyed wool, silk, mohair and cashmere fibers, including blends thereof.
