    • PURPOSE: A sheet like leather is characterized by containing elastic fiber having porous partly and having excellent elasticity, shape maintainability, shape stability, shape recoverable property, texture and drapeability. A manufacturing method thereof is provided. CONSTITUTION: A sheet like leather contains tangled non-woven fabric mixed fiber comprised of elastic polymer and super-fine fiber comprised of non-elastic fiber having below 0.1dtex of average single yarn fineness. The fiber comprised of the elastic fiber has porous partly and is fused each other partly. The sheet is obtained by the steps of: (I) manufacturing the tangled non-woven fabric comprised of fiber(A) capable of constituting the fiber comprised of the elastic fiber exposed to a surface partly and fiber capable of constituting the super-fine fiber comprised of the non-elastic fiber; (II) dipping a solution containing a good dissolving agent into the entangled non-woven fabric to dissolve partly the elastic fiber of the fiber(A); (III) dipping a solution containing a bad dissolving agent into the entangled non-woven fabric to make the dissolved elastic fiber into the elastic fiber having porous partly; and then (IV) changing the fiber(A) and the fiber(B) into the fiber comprised of the elastic polymer and the super-fine fiber comprised of the non-elastic polymer.
    • 目的:一种类似皮革的片材的特征在于含有部分多孔的弹性纤维,具有优异的弹性,形状可维持性,形状稳定性,形状可恢复性,质地和悬垂性。 提供其制造方法。 构成:皮革片包含由弹性聚合物构成的缠结无纺布混合纤维和由平均单丝细度低于0.1dtex的非弹性纤维构成的超细纤维。 由弹性纤维构成的纤维部分地具有多孔,并且部分地彼此熔合。 通过以下步骤获得片材:(I)制造由能够构成由部分暴露于表面的弹性纤维构成的纤维的纤维(A)和能够构成超细纤维的纤维构成的缠结无纺织物 由非弹性纤维组成; (II)将含有良好溶解剂的溶液浸入缠结的无纺布中以部分地溶解纤维(A)的弹性纤维; (III)将含有不良溶解剂的溶液浸渍到缠结的无纺布中,使溶解的弹性纤维进入部分多孔的弹性纤维中; 然后(IV)将纤维(A)和纤维(B)变为由弹性聚合物构成的纤维和由非弹性聚合物构成的超细纤维。
