Document Type and Number:
Japanese Patent JP2928364
Kind Code:
B2
Abstract:
PURPOSE:To provide the subject fiber having excellent processing stability and comprising a sheath-core conjugate fiber whose sheath portion comprises separable plural portions, the sea portion of whose core portion comprises a solvent-dissolvable polymer and the island portions of whose core portion form ultra-fine fibers. CONSTITUTION:The objective fiber comprises a sheath-core fiber, the sheath portion comprising a plurality of mutually separable portions 2 and 3, the core portion 1 having a sea-island structure, the sea component of the core portion 1 comprising a polymer removable with a solvent, such as PVA, and the island component comprising a polymer such as PE and forming ultra-fine fibers having a single fineness of <=0.1d. The separable portions of the sheathe portion of a woven fabric prepared of the conjugate fibers are separated from each other and the sea portions of the core portions are removed with a solvent to provide the woven fabric containing ultra-fine fibers and having excellent touch.
