    • A process for producing an entangled object for artificial leathers which includes a step in which a woven or knit fabric and an entangled nonwoven fabric are united with each other by entangling. The production process comprises: (1) a step in which a woven or knit fabric is superposed on one side of an entangled nonwoven fabric; (2) a step in which needle punching is conducted from the entangled nonwoven fabric side to cause fibers constituting the entangled nonwoven fabric to penetrate into and through the woven or knit fabric and thereby form, on the outer surface of the woven or knit fabric, a nonwoven fabric layer consisting of the fibers which have penetrated therethrough; and (3) a step in which needle punching is conducted from the nonwoven fabric layer side to fold at least part of the fibers which have penetrated through the woven or knit fabric and constitute the nonwoven fabric layer and to cause these fibers to come again into the woven or knit fabric and thereby unite the woven or knit fabric with the entangled nonwoven fabric by entangling. This production process less causes rumples, etc., and the web has the excellent property of running through the steps. An artificial leather obtained from the entangled object for artificial leathers has excellent shape stability, a highly elegant appearance, and a soft texture giving a highly fashionable feeling.
    • 一种人造革用缠结物的制造方法,其特征在于,包括编织物或针织物和缠结无纺布通过缠结而相互结合的工序。 制造方法包括:(1)在缠结无纺布的一面上重叠织造针织物的步骤; (2)从缠结无纺织物侧进行针刺的步骤,使构成缠结无纺布的纤维穿透织造针织物并穿过机织物或针织物,从而在机织或针织物的外表面上形成, 由穿过其中的纤维构成的无纺布层; (3)从非织造织物层侧进行针刺的步骤,使至少部分穿过编织物或针织物的纤维折叠并构成无纺织物层并使这些纤维再次进入 织造或编织织物,从而通过缠结将织造或针织织物与缠结的无纺织物相结合。 这种生产过程较少会导致隆起等,并且网络具有贯穿步骤的优秀特性。 从人造皮革的缠结物体获得的人造革具有优异的形状稳定性,高雅的外观和柔软的质地赋予高度时尚的感觉。

    • An artificial leather containing a web structure formed of an ultrafine fiber bundle and a polymer elastic body impregnated in the inside of the web structure. Part of the polymer elastic body is impregnated in the inside of the ultrafine fiber bundle and the ratio thereof is in the range of from 1 to 30% in terms of an area ratio at a given cross-section vertical to the longitudinal direction of the ultrafine fiber bundle. The artificial leather formed of the ultrafine fiber bundle in which the polymer elastic body is partially impregnated has an improved fiber holding property, therefore, it has a good texture without deterioration of the surface grade. ® KIPO & WIPO 2009
    • 包含由超细纤维束形成的网状结构的人造革和浸渍在纤维网结构内部的聚合物弹性体。 聚合物弹性体的一部分浸渍在超细纤维束的内部,其比例以与超细纤维的长度方向垂直的给定横截面的面积比为1〜30% 纤维束。 由聚合物弹性体部分浸渍的超细纤维束形成的人造革具有改善的纤维保持性,因此其具有良好的质地,而不会使表面等级劣化。 ®KIPO&WIPO 2009

    • A piled sheet composed of three layers entangled/united with each other. The three layers have a layer structure which is an entangled nonwoven fabric (A) made of ultrafine fibers/polyurethane sheet (B)/woven or knit fabric (C) or an entangled nonwoven fabric (A) made of ultrafine fibers/woven or knit fabric (C)/polyurethane sheet (B), wherein the entangled nonwoven fabric (A) has piles of the ultrafine fibers formed on the surface. Part of the ultrafine fibers constituting the entangled nonwoven fabric (A) pass through the polyurethane sheet (B) and the woven or knit fabric (C) in this order or through the woven or knit fabric (C) and the polyurethane sheet (B) in this order, at least part of the ultrafine fibers passing through these being bonded to the polyurethane constituting the polyurethane sheet (B). The piled sheet having such features has excellent shape retentivity, e.g., the property of not deforming even through long-term use. The sheet has satisfactory surface wearing resistance and a soft satisfactory texture giving a high-grade feeling. ® KIPO & WIPO 2008
    • 由三层组成的堆叠板彼此缠结/结合。 三层具有由超细纤维/聚氨酯片材(B)/编织物或针织物(C)制成的缠结无纺布(A)或由超细纤维/编织物或编织物制成的缠结无纺布(A)的层结构 织物(C)/聚氨酯片材(B),其中所述缠结无纺布(A)具有在表面上形成的超细纤维堆。 构成缠结无纺布(A)的超细纤维的一部分依次通过聚氨酯片材(B)和编织物或针织物(C),或通过编织物或针织物(C)和聚氨酯片材(B) 通过这些顺序,通过这些的超细纤维的至少一部分与构成聚氨酯片(B)的聚氨酯结合。 具有这种特征的堆叠片材具有优异的形状保持性,例如即使长期使用也不变形的性质。 该片具有令人满意的表面耐磨性和令人满意的柔软质感,具有高档感。 ®KIPO&WIPO 2008
