    Abstract: PURPOSE:A leathery sheet having improved appearance, feeling in touch, and colorability, having a surface layer of a sheet made of a three-dimensional entangled material of porous hollow fiber, and a silver face layer consisting of a dense entangled material of thin fiber (bundle) obtained by fibrillating and branching the porous hollow fiber and a resin on the surface layer of it. CONSTITUTION:A leathery sheet obtained by forming a silver face layer consisting of a fiber entangled material of thin fiber (preferably one having

    Abstract: PURPOSE:Silvered artificial leather that is produced by forming in turns a porous resin layer and a nonporous resin layer of specific thickness, respectively, on the surface layer of a densely interwinding fine fiber and/or bundle fabric thus showing excellent smoothness, expecially when extended. CONSTITUTION:The base material has, at least on one surface, a densely intertwinding fiber structure in which very fine fibers or bundles of less than 0.2, perferably less than 0.05 denier interwinding one another so that the distance between intercrossing points of fibers is less than 200 micros, preferably less than 100 microns. Then, a porous resin layer which is mainly composed of polyurethane elastomer of 3-500 micron, preferably 10-200 micron thickness (preferably containing gigantic pores from view points of moisture and gas permeation) and further the top coat of 0.1-20, preferably 1-10 micron thick nonporous resin layer are formed on the surface.

    Abstract: PURPOSE:The titled sheet having improved surface smoothness and flexibility, by jetting a high-speed fluid flow to a sheet of conjugated fiber of extremely thin fiber-forming type comprising components having different solvent solubility and softening point, hot-pressing it, providing it with a resin, hot-pressing it, and removing the component, successively. CONSTITUTION:At least one side of a sheet of multiple component fiber of extremely thin fiber-forming type comprising two components having different solvent solubility and softening points especially (preferably sea-island type fiber having a low softening component as the sea component) is sprayed with a high- speed fluid flow so that the fiber is split and entangled (i), hot-pressed at a temperature higher than the softening point of the low-softening component and lower than that of the high-softening component (ii), provided with (solid content), preferably solution or dispersion of a resin (preferably polyurethane elastomer) on the pressed face (iii0, the impregnated face is hot- pressed by the carving face or smooth face (iv), and the component softened by the process (ii0 is dissolved and removed (v).
