  • Velour needle-punched nonwoven material and use thereof
    Patent number: 8287983
    Abstract: 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.
