Abstract
Hot-melt-adhesive, micro-fibers-generating conjugate fibers (A), hot-melt-adhesive, micro-conjugate fibers (B) and a woven or non-woven fabric using the former fibers (A) are provided. The former fibers (A) have a sufficient tenacity and afford a stabilized spinability. The former fibers (A) have at least one conjugate portion of the conjugate fibers with an island-in-sea structure exposed onto the surface of the conjugate fiber. The sea part in the island-in-sea structure being removed by means of a solvent or the like, with the remaining island part having a fineness of 1 d or less. The other conjugate portion being a fiber composed of a thermoplastic resin having a melting point lower than that of the resin constituting the super-fine fibers and having 0.5 d or more, and the conjugate fibers having 1 d or more in total. The latter fibers (B) are those obtained by removing the sea component from the former fibers (A). The woven or non-woven fabric having micro-fibers prepared by removing the sea component from a woven or non-woven fabric using, the former fibers (A); the former fibers (A) and normal hot-melt-adhesive conjugate fibers; or the former fibers (A) applied thereonto or…
