Abstract of the Disclosure In a method for producing a soft sheet material containing thinned fibers or filaments and a viscoelastic substance, the improvement comprising: (A) applying a mixture of a viscoelastic substance and a temporary filler to a sheet Material containing thinnable fibers or filaments; (B) thinning the thinnable fibers or filaments forming said sheet material; (B') applying temporary filler to said sheet material or relocating said temporary filler applied previously at step (A) within said sheet material, whenever necessary; (C) applying a viscoelastic substance; (D) removing said temporary filler; and (E) napping the sheet, whenever necessary, to thereby obtain a leather- like sheet Material which, though soft, has good mechanical properties such as high abrasion resistance and high tear strength. A leather-like sheet material is produced which is free from deficiencies such as low abrasion re- sistance and tear strength even where the thickness is further reduced.
