Abstract (en)
Production of polyurethaneurea fibers comprises spinning a polyurethaneurea solution containing 0.1-5% of a polydimethylsiloxane with a viscosity of 2-20 cS, 0.1-5% of an alkoxylated polydimethylsiloxane and 0.01-3% of a Group Ia-IIIa metal or zinc salt of C6-C30 fatty acid (all percentages are by weight of fibers). Production of polyurethaneurea fibers comprises spinning a polyurethaneurea solution containing 0.1-5% of a polydimethylsiloxane with a viscosity of 2-20 cS, 0.1-5% of an alkoxylated polydimethylsiloxane of formula (1) and 0.01-3% of a Group Ia-IIIa metal or zinc salt of C6-C30 fatty acid (all percentages are by weight of fibers): PE = (CH2)3O(EOv/POw)mZ; EO = ethylene oxide; PO = propylene oxide; Z = H or 1-6C alkyl; v, w = 0 or more, but not both 0; x, y, m = 1 or more. An Independent claim is also included for polyurethaneurea fibers produced from a spinning solution as above, where the polydimethylsiloxane, alkoxylated polydimethylsiloxane and fatty acid salt are finely dispersed or dissolved in the fibers.
Abstract (de)
Es werden Polyurethanharnstofffasern beschrieben, die durch einen Trocken- oder Nassspinnprozess hergestellt werden und eine Mischung von Polydimethylsiloxan, alkoxyliertem Polydimethylsiloxan und Fettsäuresalz als Additiv fein dispergiert oder gelöst enthalten. Außerdem wird ein Verfahren zur Herstellung der Polyurethanharnstofffasern mit einer Mischung von Polydimethylsiloxan, alkoxyliertem Polydimethylsiloxan und Fettsäuresalz als Additiv beschrieben.
