SHEET-SHAPED OBJECT AND PROCESS FOR PRODUCING SAME |
摘要 |
The 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/cm3. 1>(A')/(B')≥0.5 (a) 1>(A")/(B")≥0.6 (b) |
