Abstract
Micro-fibers-generating conjugate fibers having a practically sufficient tenacity, a broad tolerance of spinning conditions and a stabilized spinnability, and a woven fabric or non-woven fabric prepared from the same are provided, which micro-fibers-generating conjugate fibers comprises one conjugate component of island-in-sea structure and the other conjugate component of a normal structure, the former component being exposed on the surface of the conjugate fiber and the sea part of the island-in-sea structure being removed by a solvent treatment at a later stage after or before forming into a woven or non-woven fabric to generate micro-fibers along with the fibers of the other component.
