ABSTRACT:
A surface-modified synthetic fiber is provided by plasma irradiating a synthetic fiber containing fine particles. Recesses and projections are formed on the surface of the fiber. The recesses are formed by being etched with plasma in the portion not shielded by the fine particles; the projections are formed by not being etched in the portion shielded by the fine particles. The resulting fiber has an irregular surface such that the distance between the center points of adjacent projections is between approximately 0.03 and 1 microns and the number of projections is between approximately 1 and 200 per square micron.
