    摘要: The present invention refers to a process for the preparation of a non-woven microfibrous suede-like synthetic fabric that does not require the use of organic solvents and that makes it possible to obtain a finished product offering a good hand, excellent resistance to yellowing and high durability. It comprises needle-punching a felt of sea/island fibres, (a) impregnation with hot aqueous solution of PVOH having a degree of saponification of at least 94% or (b) impregnation with hot water followed by impregnation with cold PUR, removing the sea component, impregnating with PUR, coagulating the PUR, removing the PVOH, grinding the surface, dyeing and splitting in two sheets.

    摘要: The present invention provides: a method for producing, by an eco-friendly production step, a sheet-form product that has an elegant napped appearance and that has excellent wear resistance and texture; and the sheet-form product. This sheet-form product includes a fibrous base material including ultrathin fibers with an average monofilament diameter of 0.3 to 7 [mu]m; and a water-dispersible polyurethane contained inside the fibrous base material, the water-dispersible polyurethane including both a substance having a molecular weight of 100 to 500 and having an amide bond, and inorganic particles having an average particle diameter of 1 nm to 10,000 nm. Porous particles having a BET specific surface of 5 m2/g or greater are preferably used as said inorganic particles.
