Document Type and Number:
Japanese Patent JP7226435
Kind Code:
B2
Abstract:
This sheet-shaped article comprises a polymer elastic body and a nonwoven fabric obtained from ultrafine fibers having an average single-fiber diameter of 0.1 to 10 µm. The sheet-shaped article is characterized in that the polymer elastic body is a polyurethane resin obtained using, as the reaction components, the following: a polycarbonate diol containing structural units derived from a C8-20 alkane diol; an organic diisocyanate; and a chain extender. The sheet-shaped article is also characterized in that the bending and crease recovery rate thereof is 80 to 100%.
