Claims
- 1. A method for preparing a three dimensional fabric having a face surface, an opposite fabric surface and a piled body of pile fibers therebetween, the steps comprising heating and compressing the face surface of said pile fibers to adhere adjoining pile fibers at said face surface with each other, form apexes over a wide surface area and make thereby a film-shaped surface, and thereafter crumpling said film-shaped surface and splitting said film-shaped surface into film-shaped surface units of smaller area.
- 2. A method for preparing a three dimensional fabrics as recited in claim 1 in which the step of heating and compressing is carried out with calendar rolls.
- 3. A method for preparing a three dimensional fabric as recited in claim 1 wherein said piled fiber is an ultra-fine synthetic fiber.
- 4. A method for preparing a three dimensional fabric as recited in claim 1 including the further step of adhering a resin to the surface layer of said fabric before said film-shaped surface is crumpled.
- 5. A method for preparing a three dimensional fabric as recited in claim 1 including the further step of adhering a resin to at least said film-shaped surface units of smaller area after forming said units of small area by said crumpling.
- 6. A method for preparing a three dimensional fabric as recited in claim 3 wherein said ultra-fine synthetic fiber is of monofilament having a denier of 1 or less.
- 7. A method for preparing a three dimensional fabric as recited in claim 3 wherein said ultra-fine synthetic fiber is monofilament having a denier of 0.5 or less.
