Abstract
Hydrophilic polyolefin fibers containing more than 50 weight % of basic pigment, are obtained if a mixture of polyolefin, a solvent for this polyolefin, a basic pigment, a hydrophilization agent, water and an organic acid flows from a pressure vessel through a nozzle into a low-pressure chamber. The thus obtained fibers may be used for preparing synthetic paper without requiring much expenditure for work-up.
