Abstract
The present invention relates to an acrylic fiber having excellent water absorbency. The fiber has a porous core and a relatively dense skin structure. It is a blended polymer which comprises an acrylic polymer copolymerized with a synthetic polymer which is miscible but substantially incompatible therewith, and is soluble in a solvent for the acrylic polymer but is insoluble in water.
