PROBLEM TO BE SOLVED: To provide trifoliate cross-section fiber having excellent see-through-proof effect, slight in the abrasion of guides and the like in respective steps therefor including spinning and post-processings, giving good color developability after dyed, and furnished with unconventionally powdery touch, and to provide woven/knitted fabrics comprising the fiber. SOLUTION: The trifoliate cross-section fiber is such that, among its three sides, there are inorganic particles on the respective surface layers of two of the sides and there are no inorganic particles on the surface layer of the rest of the sides. It is more preferable to be 0.5-1.5 mass% in the inorganic particles' content of the fiber. COPYRIGHT: (C)2007,JPO&INPIT
