Abstract (en)

Basically modified carbon black (I) is used to produce dark polyurethaneurea fibers, where (I) is uniformly dispersed in the fibers in an amount of 0.05-8 wt.%. Independent claims are also included for: (1) polyurethaneurea fibers comprising 70-99.9 wt.% polyurethaneurea, 0.05-8 wt.% (I) and 0-20 wt.% additives, where (I) is uniformly dispersed in the fibers; (2) producing colored polyurethaneurea fibers by preparing a polyurethaneurea solution containing 0.05-8 wt.% (I), spinning the solution, forming fibers by drying or precipitation, and lubricating and spooling the fibers.
