ABSTRACT:
Polyurethane elastomeric filaments of improved physical properties and chemical resistance prepared by preforming the filamentary material such that the polyurethane contains at least about 100 up to about 700 milliequivalents/kilogram of reactive terminal amino groups, and then aftertreating this preformed filamentary polyurethane, optionally under simultaneous stretching, with an organic polyisocyanate and then preferably heating the treated material at an elevated temperature above about 140.degree.C. The polyurethane filamentary product is particularly useful in providing durable elastic filaments, fibers, threads, yarns, fabrics and similar textile materials.
