ABSTRACT:
Surface-modified cellulose acetate filaments having a microporous structure located in the peripheral surface layer thereof are prepared by bringing non-modified cellulose acetate filaments which have an average degree of acetylation of 50 to 62% into contact with an organic solvent which is capable of dissolving or swelling the non-modified filaments and by rapidly evaporating the solvent from the filaments. The microporous structure causes the surface-modified filaments to exhibit a desirable silklike touch and an increased intensity in dye exhaustion of from 1.1 to 2.0 times that of the non-modified filaments.
