    摘要: 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 are disclosed. 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).

    摘要: A sheet is produced by (i) producing a sheet by entangling woven or knitted material including a thread composed of a composite fiber such that two kinds or more of polyethylene terephthalate polymers different in intrinsic viscosity are stuck together in a side-by-side type along the fiber length direction and/or of a core-in-sheath type composite fiber such that two kinds or more of polyethylene terephthalate polymers different in intrinsic viscosity form an eccentric core-in-sheath structure, with a fiber capable of converting into ultra fine fibers composed of two kinds or more of polymeric substances different in solubility in solvent, (ii) developing an ultra fine fiber with an average single fiber fineness of 0.001 dtex or more and 0.5 dtex or less by treating the sheet with a solvent to thereafter provide elastomer having polyurethane as a main component by impregnating and solidifying solvent solution of elastomer having polyurethane as a main component into the sheet, or of providing elastomer having polyurethane as a main component by impregnating and solidifying solvent solution of elastomer having polyurethane as a main component into the sheet to thereafter develop an ultra fine fiber with an average single fiber fineness of 0.001 dtex or more and 0.5 dtex or less by treating the sheet with a solvent, and (iii) rubbing and shrinking the woven or knitted material under the condition of 110° C. or more.
