Sheet Shaped Object And Process For Producing Same
Abstract: 3The present invention provides: a sheet shaped object which is thin and despite this has a surface that is dense and is soft to the touch and which has practicable strength; and a process for producing the sheet shaped object. This sheet shaped object comprises ultrafine fibers having an average single fiber diameter of 0.1 7 µm and a polymeric elastomer comprising a polyurethane as a major component wherein when a layer extending from one surface to a depth of 50% of the thickness is referred to as layer (A) and a layer extending from the other surface to a depth of 50% of the thickness is referred to as layer (B) then the ratio of the density of fibers (A ) in the layer (A) to the density of fibers (B ) in the layer (B) satisfies the following expression (a) and the ratio of the density of the polymeric elastomer comprising a polyurethane as a major component (A") in the layer (A) to the density thereof (B") in the layer (B) satisfies the following expression (b). The sheet shaped object as a whole has a density of 0.2 0.6 g/cm. 1>(A )/(B )=0.5 (a) 1>(A")/(B")=0.6 (b)
