The invention describes a velour needle-punched nonwoven material, which is produced by placing an optionally pre-strengthened nonwoven material on a brush-like stitch base and needling of the nonwoven on this stitch base. The velour needle-punched nonwoven material according to the invention is characterized in that the nonwoven material comprises a spun-bound nonwoven with filaments, wherein the filaments comprise multicomponent filaments with at least one component with a high melting point and at least one thermally activatable component with a low melting point. The velour needle-punched nonwoven material according to the invention not only has excellent mechanical properties, it is also particularly compatible with the environment and health and therefore suited for applications as a textile lining not only in the private field, but particularly in the public domain.

1. A velour needle-punched nonwoven material, which is produced by placing an optionally pre-strengthened nonwoven material on a brush stitch base support and needling of the nonwoven on this stitch base, characterized in that the nonwoven material comprises a spun-bound nonwoven with filaments and staple fibers admixed in the spunbond nonwoven up to 75% of the total base weight of the velour needle-punched nonwoven material, the filaments comprising multicomponent filaments with at least one component with a high melting point and at least one thermally activatable component with a low melting point and wherein said velour needle-punched nonwoven is a thermally bonded nonwoven and said multicomponent filaments function as a binding agent. 2. The velour needle-punched nonwoven material according to claim 1, characterized in that the multicomponent filaments comprise bicomponent filaments. 3. The velour needle-punched nonwoven material according to claim 2, characterized in that the portion of the bicomponent filaments is greater than 5%, in relation to the overall weight of the velour needle-punched nonwoven material. 4. The velour needle-punched material according to claim 2, characterized in that the bicomponent filaments are configured as sheath/core, side-by-side, island-in-the-sea, hollow pie or pie filaments. 5. A velour needle-punched nonwoven material according to claim 2, characterized in that the component with a low melting point of the bicomponent filaments comprises copolyester, copolyamide, polyamide, polypropylene, copolypropylene, atactic polypropylene or polyethylene. 6. A velour needle-punched nonwoven material according to claim 2, characterized in that the component with a high melting point comprises polyester, polylactide, polybutylene, polyamide or polypropylene. 7. A velour needle-punched nonwoven material according to claim 1, characterized in that the staple fibers and/or filaments comprise curled staple fibers and/or filaments. 8. A textile lining comprising at least one layer forming a velour surface made of a velour needle-punched nonwoven material, characterized by a velour needle-punched nonwoven material according to claim 1. 9. The textile lining according to claim 8, characterized in that on the rear surface of the textile lining facing away from the velour surface a heavy layer is provided comprising polyethylene, calcium carbonate and ethylene vinyl-acetate, or nonwoven material. 10. The textile lining according to claim 8, characterized in that on the rear surface of the textile lining facing away from the velour surface a sound damping layer is provided. 11. A textile lining according to claim 8, characterized in that bonding layers are provided between individual or all layers. 12. The textile lining according to claim 11, characterized in that the bonding layers comprise fibers and/or filaments made of a polymer with a low melting point. 13. A textile lining according to claim 11, characterized in that the bonding layers comprise multicomponent fibers and/or filaments, comprising at least one component with a high melting point and at least one component with a low melting point. 14. A textile lining according to claim 12, characterized in that the polymer with a low melting point or the component with a low melting point of the multicomponent or bicomponent fibers and/or filaments comprises copolyester, copolyamide, polyamide, polypropylene, atactic polypropylene or polyethylene. 15. The textile lining according to claim 14, characterized in that the component with a high melting point comprises polyester, polyamide, polylactide, polybutylene or polypropylene. 16. A textile lining according to claim 13, characterized in that the multicomponent fibers and/or filaments comprise bicomponent fibers and/or filaments, wherein said bicomponent fibers and/or filaments are configured as sheath/core, side-by-side, island-in-the-sea, hollow pie or pie filaments. 17. A textile lining according to claim 9, characterized in that the filaments and/or fibers of all layers are made of one and the same polymer and/or the derivatives thereof. 18. The textile lining of claim 8, wherein said textile lining is in the form of a lining for interior motor vehicle spaces. 19. The textile lining of claim 8, wherein said textile lining is in the form of carpeting.
