Abstract

PURPOSE: To obtain a porous sheet of improved dye-affinity by impregnating a nonwoven fabric of polyamide fibers with a polyurethane elastomer dissolved in an organic solvent, incorporated with a dye-affinity improver to which a specific aliphatic diamine is bound, and solidifying the fabric. CONSTITUTION: This porous sheet-like product is obtained by impregnating a nonwoven fabric of polyamide fibers with a polyurethane elastomer dissolved in an organic solvent, and solidifying the fabric, wherein the solution of organic solvent is incorporated with 1 to 30 wt.%, based on the solid elastomer, of a dye-affinity improver, with two aliphatic diamine molecules bound thereto, the aliphatic diamine having tertiary amino group and primary amino group, and/or tertiary amino group and secondary amino group, at both terminals of the polyol via an organodiisocyanate. This sheet-like product can be dyed uniformly, without causing uneven dyeing, to have soft feel of touch.
