  • Publication number: 20100255270
    Abstract: The present invention provides a fabric and a fabric structure made of yarns with reduced water absorption. The fabric comprises yarns and interstices between the yarns, the interstices between the yarns having an average width of greater than 100 ?m. At least one of the yarns is comprised of multiple fibers. Said at least one yarn has voids between the fibers wherein the voids are filled up with a polymer material. The interstices remain open and the size of the interstices is the same as before the treatment. The filling of the voids between the fibers with the polymer material prevents the absorption of water into said voids and therefore leads to reduced water absorption of the fabric. The polymer material is substantially only located within the voids of the yarn and has embedded the fibers within the outer surface of said yarn.

  • Patent number: 7786032
    Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.

  • Publication number: 20100167615
    Abstract: The present invention describes a process for the surface finishing of materials via application of specific polymethacrylate layers. The polymethacrylate layers are composed of blends of at least two (co)polymers of polymethacrylates, and specific “reactive monomers” are present here in a polymerized mixture which forms the polymethacrylate layer. At the application temperature established, these form a chemical and, where appropriate, also a physical bond to the substrate, and therefore have adhesion-promoting action.
