Abstract
Official abstract text for this publication.
Disclosed is a colored napped artificial leather including: a fiber-entangled body including ultrafine fibers having an average single fiber fineness of 0.5 dtex or less; and an elastic polymer impregnated into the fiber-entangled body, the napped artificial leather having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers, wherein the napped artificial leather further includes particles of a fatty acid amide-based compound that are at least attached to surfaces of the ultrafine fibers and that have an average particle size of 0.1 to 10 μm.
First claim
Opening claim text (preview).
1 . A colored napped artificial leather comprising: a fiber-entangled body including ultrafine fibers having an average single fiber fineness of 0.5 dtex or less; and an elastic polymer impregnated into the fiber-entangled body, the napped artificial leather having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers, wherein the napped artificial leather further comprises particles of a fatty acid amide-based compound that are at least attached to surfaces of the ultrafine fibers and that have an average particle size of 0.1 to 10 μm. 2 . The napped artificial leather according to claim 1 , wherein the particles of the fatty acid amide-based compound are attached to the ultrafine fibers constituting the napped surface. 3 . The napped artificial leather according to claim 1 , wherein the fatty acid amide-based compound has a melting point of 110° C. or more. 4 . The napped artificial leather according to claim 1 , wherein a content ratio of the particles is 0.2 to 5 mass %. 5 . The napped artificial leather according to claim 1 , wherein the napped surface has a lightness L* value of 40 or less in a color coordinate space (L*a*b* color space). 6 . A method for producing a napped artificial leather, comprising: preparing a napped artificial leather gray fabric including a fiber-entangled body of ultrafine fibers having an average single fiber fineness of 0.5 dtex or less, and an elastic polymer impregnated into the fiber-entangled body, the napped artificial leather gray fabric having, at least on one side thereof, a napped surface formed by napping the ultrafine fibers; and applying, to the napped artificial leather gray fabric, a dispersion of particles of a fatty acid amide-based compound that have an average particle size of 0.1 to 10 and drying the dispersion at a temperature less than a melting point of the fatty acid amide-based compound.
