发明名称 Treatment of fiberfill fibers with aqueous dispersions of organopolysiloxanes
摘要 <p>Treatment of fiberfill fibers includes contacting fibers with aqueous dispersion of organopolysiloxane obtained by reacting organopolysiloxane comprising condensation-capable groups and specific siloxane units with silane or its hydrolysate in the presence of water and emulsifier. Treatment of fiberfill fibers includes contacting fibers with aqueous dispersion of organopolysiloxane obtained by reacting organopolysiloxane comprising condensation-capable groups and units of formula R a(OR 1>) bSiO (4-(a+b))/2(I) with silane of formula (R 3>O) 3SiCR 2>2-Y (II) or its hydrolysate in the presence of water, emulsifier, optionally further silane of formula (R 3>O) xR 3-xSi-R 6>-Z (III) or its hydrolysate, and optionally further materials which do not take part in the reaction of organopolysiloxane with silane (II). Provided that no metal-containing catalysts are used and the organopolysiloxane and silane (II) are used in such amounts that the organopolysiloxane forms toluene-insoluble elastomeric film after removal of water. R : H or 1-18C monovalent hydrocarbyl optionally substituted with heteroatoms N and/or O; R 1>H or 1-8C alkyl, preferably H, Me, or Et; a : 0-3; b : 0-2; R 2>1-4C monovalent alkyl or preferably H; R 3>1-8C alkyl; Y : -NHR 4>, -NR 4>2, or -NR 5>; R 4>1-18C monovalent hydrocarbyl optionally containing N and/or O; R 5>3-12C divalent hydrocarbyl optionally containing N and/or O; R 6>3-18C divalent hydrocarbyl; Z : amino, aminoalkylamino, epoxy, or (meth)acryloyloxy; and x : 1-3. Provided that a+b is = 3 and the organopolysiloxane contains an average OR 1>radical(s)/molecule.</p>
