Abstract: The object of the invention is a strengthened fibre fleece from staple fibres containing as strengthening agent a copolymer based on acrylic and/or methacrylic acid esters and styrene. The copolymer contains additionally in copolymerised form a monomer having nonconjugated carbon double bonds, acrylic acid and methacrylic acid, and methacrylamido-N-methylolmethylether. In a process for producing the strengthened fibre fleece, the fibre fleece is impregnated with an aqueous dispersion of the copolymers and subsequently dried at temperatures between 60* and 130*C.

Abstract: A high bulk bonded non-woven fibre fleece containing natural and/or synthetic fibres and binder fibres, which are adhesive at higher temperatures, said binder fibres consisting of a saponified ethylene-vinyl acetate copolymer, the molar ratio of vinyl acetate to ethylene in said copolymer before saponification being in the range of 1:1 to 1:20. In the process to produce the bonded fleece, the fibres containing 5 to 50 percent by weight of binder fibres are formed to a non-woven fleece and the formed fleece is heated to temperatures of above 110* C, to render adhesive the binder fibres.
