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.

The present invention relates to a process for preparing a microfibrous non-woven synthetic suede-like fabric, which does not require the use of organic solvents and which enables a soft finished product to be obtained that is provided with a good hand, that is elastic and with excellent resistance to yellowing and high durability.

Fibrous material webs and methods of making the fibrous material webs. Binderless webs can be formed in a continuous process where fiber material, such as glass is melted and formed into fibers. The fibers are formed into a web of binderless glass fibers or a web with a dry binder. The binderless web or the web with dry binder can be layered and/or the fibers that make up the web can be mechanically entangled, for example, by needling.

The object of the present invention is to provide an interior trim surface material with a more excellent texture. The interior trim surface material of the present invention comprises a print layer on at least one main surface of a fiber aggregate, and has a main surface (a main surface on which the print layer is exposed in the interior trim surface material) with a surface roughness (SMD) of less than 2.71 m and an average frictional coefficient (MIU) of more than 0.27. When these conditions are satisfied, it is possible to provide an interior trim surface material that has an excellent texture, such as a feeling of high moistness, while still imparting a sensation that feels smooth and fine texture. Further, the interior trim surface material of the present invention comprises a print layer containing hollow particles having an average particle size of 106 m or less, whereby a feeling of resistance or sliminess is imparted, thereby achieving an interior trim surface material with a more excellent texture, such as a feeling of high moistness.
