PROCESS FOR PRODUCING SHEET-LIKE FORMATIONS BY USING A MIXTURE OF FIBERS AND FOAMABLE MATERIAL AS WELL AS FOAMABLE MATERIAL

摘要

The invention relates to a method for the production of flat structures using foamable material and fibers with a high fineness coefficient. The foamable material is applied by spinning or is foamed totally or partially thereafter on the flat structure by applying energy. Fibers with a fineness coefficient greater than 50 are used. A considerable enlargement of the active surface is achieved by using foamed or post-foamed fibers. This leads to a reduction in bonding agent or binding fiber consumption and in thickness. A reduction in material consumption and costs is also achieved. Insulation values are improved while emissions are reduced.
