  • Patent number: 6248440
    Abstract: A method for obtaining a floor covering comprising one or more resilient polymer substrates coated with a protective layer is described, wherein said layer contains one or more amorphous inorganic components and has a Vickers hardness of more than 1 GPa and a modulus of elasticity (Young's modulus) of less than 80 GPa, using a delayed cold plasma that induces a decomposition reaction of a volatile precursor compound so that a thin film of said amorphous inorganic component is formed on said substrate. A floor covering comprising one or more resilient polymer substrates obtained by the method of the invention is also described, wherein the substrate is coated with a protective layer containing one or more amorphous inorganic components and with a Vickers harness of more than 1 GPa and a modulus of elasticity (Young's modulus) of less than 80 GPa.

  • Patent number: 6012205
    Abstract: A method for making a textile product from a web of fibers and/or filaments moving in a feed direction. The method comprises a pre-looping step in which the fibers and/or filaments are individually transversely looped relative to the feed direction and optionally transversely stretched, whereafter they pile up in the form of a crimped pseudo-yarn in which the fibers and/or filaments are parallelized. Prior to the pre-looping step, the method comprises a crimping step in which the fibers and/or filaments are crimped with a spacing and a depth that are a multiple of the spacing and depth of the "crimp" formed in the pre-looping step.
