Abstract
A sheet material is formed of a base cloth consisting of a woven fabric, knit fabric, nonwoven fabric, or web material having a favorable form stablity and a short fiber material consisting at least partly of a natural fiber material, said sheet material having a structure in which said base cloth is covered on at least one surface with the short fiber material and a part of the short fiber material is stuffed into the gaps in the network of the base cloth so that the base cloth and short fiber material are substantially integrated with each other.

A method of producing sheet materials, comprising:
- laminating a web material of a short fiber material consisting at least partly of a natural fiber material on a base cloth formed of fibers having a latent shrinkability;
- subjecting said laminate to high pressure liquid jet streams on said web material surface so that said base cloth and web material are substantially integrated with each other;
- and then shrinking the obtained sheet.

- subjecting said laminate to a high pressure liquid jet stream on said web material surface so that said base cloth and web material are substantially integrated with each other;
- shrinking said sheet, and then incorporating an elastic polymer in said integrated laminate in an amount of less than 50% based on the total weight of the base cloth and short fiber material.
