Suede-finished leather-like sheet and production method thereof |
摘要 |
<p>The suede-finished leather-like sheet of the present invention comprises a fiber-entangled nonwoven fabric comprising a layer (I) made of a microfine fiber (A) having an average fineness of 0.5 dtex or less and a layer (II) made of a microfine fiber (B) having an average fineness equal to or less than that of the microfine fiber (A), and a polymeric elastomer impregnated in the fiber-entangled nonwoven fabric. The layers (I) and (II) are integrated by entanglement such that a ratio of the microfine fiber (A) to the microfine fiber (B) is 10/90 to 90/10 by mass. The surface of the layer (I) is a napped surface made mainly of a raised microfine fiber (A). The microfine fibers (A) and (B) are respectively formed by converting a microfine fiber-forming fiber (a) and a microfine fiber-forming fiber (b), each having an elongation at break and a tenacity of specific ranges, into microfine fibers. The suede-finished leather-like sheet simultaneously exhibits a soft feel like natural leathers and good mechanical properties, especially good shape stability and tear strength.</p> |
