    摘要: The leather-like sheet substrate of the present invention comprises a fiber-entangled nonwoven fabric that comprises a microfine fiber bundle (A) and a microfine fiber bundle (B) in a blending ratio (A)/(B) of 30/70 to 70/30 by mass and a polymeric elastomer contained in the fiber-entangled nonwoven fabric. The microfine fiber bundle (A) comprises 10 to 100 microfine fibers each of which has a single fiber fineness of 0.5 dtex or less and which are made of an elastic polymer having a JIS A hardness of 90 to 97. The microfine fiber bundle (B) comprises a microfine fiber which has a single fiber fineness of 0.5 dtex or less and which is made of a non-elastic polymer. Because of its excellent stretchability in both the machine and transverse directions and drapeability, the leather-like sheet substrate is particularly suitable as the material for clothing.

    摘要: A method of producing an entangled sheet of microfine long fibers using long fibers for forming microfine fibers. The method includes a step of forming a long-fiber web made of long fibers for forming microfine fibers, at least one component of the long fibers being a water-soluble, thermoplastic polyvinyl alcohol resin; a step of entangling the long-fiber web to form a long-fiber entangled sheet; a step of shrinking the long-fiber entangled sheet to form a long-fiber shrunk sheet; and a step of converting the long fibers for forming microfine fibers in the long-fiber shrunk sheet to microfine long fibers, thereby producing the entangled sheet of microfine long fibers. The step of entangling is conducted so as to allow the long-fiber entangled sheet to have an interlaminar peel strength of 2 kg/2.5 cm or more. The step of shrinking is conducted so as to shrink in an areal shrinkage of 35% or more.

    摘要: In accordance with the present invention, it has now been found that the coagulation property of polyurethane elastomers can be considerably improved without spoiling any desirable chemical property of the original elastomer, if polyurethane elastomers which are different only in N%, are mixed together in a specified range of mixing ratio or if a polyurethane elastomer is synthesized using a mixture of polymer glycols whose structural units are chemically the same, however, whose molecular weights are different from each other in a specified range, and a solution of the obtained elastomer is coagulated by a specified wet coagulation condition.
