<p>A composition for rendering polyolefin fibres, filaments or nonwovens permanently hydrophilic comprises: (A) 15-75 parts by weight at least one nonionic surfactant; and (B) 25-85 parts by weight of a component comprising at least one quat. ammonium (sic) compound of formula (I) and/or at least one cationically modified polydimethylsiloxane of formula (IIa) or (IIb): ÄR<1>-C(O)-X-(CH2)n-N(R<2>)(R<3>)-(CH2)m-X-C(O)-R<1>Ü<+> Y<-> (I) R<4>-Si(CH3)2-O-ÄSi(CH3)2-O-ÜrSi(CH3)2-R<4> (IIa) CH3-Si(CH3)2-O-ÄSi(CH3)2-O-Ür-ÄSi(CH3)(R<4>)-O-ÜsS i(CH3)2-CH3 (IIb) R<1> = 1-18C alkyl or 2-18C alkenyl; R<2>, R<3> = 1-18C alkyl, hydroxyethyl or polyglycol; X = O, NH, N-CH3 or (OC2H4)z-; z = 1-10; Y = CH3OSO3<->, C2H5OSO3<->, CH3COO<->, Cl<->, phosphate or lactate; m, n = 1-6; r, s = 1-50; R<4> = group of formula: (CH2)q-O-CH2-CH(OH)-CH2-NR<5+.> Y<-> or (CH2)q-O-CH2-CH(OH)-CH2-N<+)<R<5>)2-Z Z = CH2COO<-> or CH2-CH2-CH2-NH-CO-R<6>.Y<->; R<5> = methyl or C2H4OH; R<6> = optionally unsaturated 4-22C alkyl; and q = 3-18. Also claimed are: (i) the use of the composition for the above permanent hydrophilic treatment, (ii) polyolefin fibres or filaments made hydrophilic using this composition and (iii) nonwovens comprising these hydrophilic fibres or filaments.</p> |
