ABSTRACT:
A process for the production of bulky, fiber-containing textile sheet material fills a material of loose fibers with a binding agent of an aqueous polymer dispersion containing a foaming adjuvant and puffs it up to a multiple of its original volume by the action of radiofrequency radiation in the range from 30 kHz to 30 GHz. The volume increase is then made permanent by drying. Even cellulosic fibers which formerly matted down when wet can be treated in the stated manner. The puffed textile sheet material is usable as padding for articles of clothing, for sound and heat insulation soft and resilient packing materials, clothing, protective padding and the like, but especially for products which are to absorb liquids to a relatively great extent.
