PURPOSE: To provide the subject fiber sheet-like article having excellent strength, bulkiness and voluminous touch and useful for clothes, etc., by adding a resin composition solution such as a natural resin to a fiber composition capable of being formed into fibrils, such as vegetable fibers, drying, crumpling and self-cross-linking the treated fiber composition.

CONSTITUTION: The objective fiber sheet is characterized by treating a fibril- forming fiber composition comprising a kind of fibers selected from vegetable fibers and fibril-forming chemical fibers or synthetic fibers, their blend, etc., with a resin composition consisting mainly of a natural resin, a synthetic resin, a wax, etc., or a resin-foaming composition such as a finely foamed resin solution or a foaming agent-containing resin as a seizing agent, or with a paper solution as a part of the seizing agent to produce paper, or by integrating the fibril-forming fiber composition with a fiber sheet such as cloth or paper, followed by drying and crumpling the produced paper or sheet-like product to partially or wholly loose the entanglements of the fiber tissue or by creasing and simultaneously or subsequently self-cross-linking or reacting or foaming the sheet-like product.
