Abstract (en)
[origin: WO9514803A1] The proposed multi-layered needle punched nonwoven fabric comprises at least one staple fibre layer (1, 2) and has as a high-strength support (3) a staple fibre nonwoven fabric made of bi-component fibres of high tensile strength and low streching which is drawn before needle punching with the staple fibre layer. After needle punching with the staple fibre layer (1, 2), the material undergoes heat treatment and simultaneous compression. This makes it particularly suitable as a belt material for conveyor belts.
