ABSTRACT:
A non-woven solidified by means of a melt binder is described, which is based on supporting aramid fibers and on binding fibers made of thermoplastic aramids whose melting point is below the melting or decomposition point of said supporting aramid fibers. In the non-woven, the binding fibers are virtually completely melted. The non-wovens are distinguished by high strength.
