NON-WOVEN VELOUR FABRIC AND ITS APPLICATION

The non-woven fabric used, is a spun-bonded fleece. This is optionally pre-bonded. It contains multi-component filaments, including at least one high-melting component and at least one low-melting component. The latter can be thermally-activated. Bi-component filaments are used, in a proportion preferably exceeding 15%, based on the total fabric weight. The filament structure is core/casing, side-by-side, island-in-the-sea and/or pie (or hollow pie). The low melting component is CoPET, CoPA, PA, PP, CoPP, atactic PP and/or PE. The high-melting component is PET, PLA, PBT, PA and/or PP. The spun fleece contains up to 75 wt% of staple fibers. The fibers and/or filaments are crimped. At least one layer forming a velour surface is included; this is made from needled fleece as described. A heavy backing layer is included on the rear of the velour surface, optionally with a sound-damping layer. One or more bonding layers are included between the other layers. These include fibers or filaments of low- and high-melting polymer as described. The filaments and/or fibers of all layers are made from the same polymer and/or its derivatives.
