ABSTRACT:
A process for producing a non-woven fabric of ultrafine polyolefin fibers by subjecting a web of splittable conjugate polyolefin fibers to a water needle processing, and non-woven fabric thus obtained are described. The polyolefin composite fibers, contain 1.0 to 7.0% by weight of a hydrophilic component blended therein. The non-woven fabrics include ultrafine fibers having a size of 0.5 denier or less and a non-circular cross-section. Splitting and peeling off of the conjugate fibers and generation of static electricity with the composite fibers at a carding step is suppressed. The non-woven fabrics have an excellent wiping property, softness, and hydrophilic property.
