    摘要: A method of producing an entangled fabric for artificial leathers including a step of uniting a woven/knitted fabric and an entangled nonwoven fabric by entanglement. The method includes (1) a step of superposing the woven/knitted fabric on one surface of the entangled nonwoven fabric; (2) a step of needle-punching the superposed body from a side of the entangled nonwoven fabric so as to allow fibers constituting the entangled nonwoven fabric to enter into the woven/knitted fabric and then penetrate through the woven/knitted fabric, thereby forming a nonwoven fabric layer composed of the penetrated fibers on an outer surface of the woven/knitted fabric; and (3) a step of needle-punching from a side of the nonwoven fabric layer so as to allow a part of the fibers which have penetrated through the woven/knitted fabric and form the nonwoven fabric layer to turn back into the woven/knitted fabric, thereby uniting the woven/knitted fabric and the entangled nonwoven fabric together by entanglement. The method hardly causes wrinkles, etc. and is good in process passing properties. The artificial leathers produced from the entangled fabric for artificial leathers have a good shape stability, a high-quality appearance and a soft, high quality hand.

    摘要: A raised sheet composed of three layers which are united by entanglement. The three layers are united in a layered structure of entangled nonwoven fabric A made of microfine fibers/polyurethane sheet B/woven or knitted fabric C or a layered structure of entangled nonwoven fabric A made of microfine fibers/woven or knitted fabric C/polyurethane sheet B. On the surface of the entangled nonwoven fabric A, raised naps of the microfine fibers are formed. A part of the microfine fibers constituting the entangled nonwoven fabric A penetrates through the polyurethane sheet B and the woven or knitted fabric C in this order, or penetrates through the woven or knitted fabric C and the polyurethane sheet B in this order. At least a part of the penetrated microfine fibers bonds to polyurethane which constitutes the polyurethane sheet B. The raised sheet is excellent in the shape stability, for example, it does not lose its shape even after a long term use. In addition, the raised sheet has a good surface abrasion resistance and a soft and high-quality hand.

    摘要: An artificial leather including an entangled body made of bundles of microfine fibers and an elastic polymer impregnated into the entangled body. A part of the elastic polymer penetrates into the bundles of microfine fibers. The degree of penetration of the elastic polymer is from 1 to 30% by area when measured on a cross section which is taken along a direction perpendicular to a lengthwise direction of the bundles of microfine fibers. The fiber-holding property is improved by the elastic polymer which partly penetrates into the bundles of microfine fibers, and therefore, the artificial leather has a good hand without deteriorating the surface quality.

    摘要: A colored polyamide fiber composed of a polyamide resin, a pigment, a coupling agent and a compound represented by the following formula I: R′—CO—NH—R—NH—CO—R″  (I) wherein R is an alkylene group having 1 to 4 carbon atoms, and R′ and R″ are each independently an aliphatic hydrocarbon group having 9 to 18 carbon atoms. The colored polyamide fibers are produced without causing bending and fiber break during the melt spinning even when the raw composition contains the pigment in a high concentration. Since the pigment is uniformly dispersed throughout the colored polyamide fibers, the coloration is deep and the strength is high. The colored polyamide fibers are suitable for the production of artificial leathers.
