Polyurethane-urea fibres with improved resistance |
摘要 |
Polyurethane-urea compositions are described, and, in particular, elastic polyurethane-urea fibers are described which result therefrom and which contain a dialkylsulphosuccinate as a finely dispersed or dissolved additive which considerably increases the strength of the fibers. Moreover, a method is described of producing polyurethane-urea fibers using a dialkylsulphosuccinate as an additive. |
