A composite fiber and polyolefin microfibers made therefrom.

摘要

Disclosed is a composite fiber comprising at least two different polymers, one of which is a water-insoluble polyolefin and the other is a water-soluble polymer, having a plurality of at least 19 segments of the water-insoluble polyolefin, uniformly distributed across the cross-section of the fiber and being surrounded by the water-soluble polymer, a process for the manufacture of such a fiber and a process for the manufacture of microfibers therefrom.
