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.
Claims5
Micro-fibers-generating conjugate fibers, wherein at least one conjugate component of said fibers has an island-in-sea structure, said micro-fibers-generating conjugate fibers has a fineness of one denier or more, the other conjugate component of said micro-fibers-generating conjugate fibers has a fineness of 0.5 denier or more, said at least one conjugate component having an island-in-sea structure is exposed on the surface of said micro-fibers-generating conjugate fibers, the sea part of said conjugate component is removable by a solvent treatment, the island part of said conjugate component after removing the sea part has a fineness of 0.1 denier or less.
