  • Publication number: 20070298209
    Abstract: A textile substrate is patterned by the selective application of various dyes to the substrate surface in a way that provides desirable, visually apparent enhancements in the area of pattern detail, definition, and color range, through the use of a novel patterning system, including the application of various chemical agents, that makes such enhancements possible. In one embodiment, the patterning system described herein is capable of producing pile-faced textile substrates, useful as floor coverings, that exhibit a unique combination of desirable pattern attributes that have been identified and measured using novel techniques specifically developed for these substrates and pattern attributes.

  • Publication number: 20070204444
    Abstract: Compositions and methods for treating textile substrates to obtain superior liquid repellent properties are disclosed. Durable microscopic surface structures imparted to the fibrous substrate allow liquids to bead up and roll off of its surface. Mechanical abrasion or sanding techniques may be used to create the microscopic surface structures on the surface of a fibrous textile substrate, without substantially breaking fibers, followed by a chemical treatment using, for example, fluorocarbon-containing repellent compositions. Particles may be employed in combination with repellent compositions to achieve superior repellent properties. A property of the roughened surface fibers, the Roughness Factor, is used to characterize the microscopic surface structures on the treated textile surface. Treated textile substrates are disclosed which achieve superior water and oil repellency, even after multiple abrasion or laundering cycles.

  • Publication number: 20070037462
    Abstract: This disclosure generally pertains to a method for manufacturing a distributed optical fiber scrim comprising a functional optical fiber, the functional optical fiber scrim thus manufactured, and composites in which an optical fiber scrim is incorporated. The present disclosure describes a variety of textile scrims, particularly adhesively bonded nonwoven scrim materials, each comprising at least one optical fiber with a continuous path across at least the length or width of the fabric. Such optical fiber scrims may be useful as sensor components (for example, as a detector of breakage, strain, pressure, or torque), as illumination components (for example, in a variety of light-providing applications), or as data-distribution components, either alone or in combination with other materials, such as fabrics, films, foams, and the like.

  • Publication number: 20060213233
    Abstract: The present disclosure relates to a tape that comprises a weft-inserted warp knit fabric, which utilizes a combination stitch to secure the wales of the fabric. The combination stitch comprises a majority of successive chain stitches that are used with a minority of subsequent successive tricot stitches, such that the stitch follows the expression x+y, where x is the number of successive chain stitches and y is the number of subsequent successive tricot stitches. Contemplated x values are in the range of 5 to 15, and contemplated y values are in the range of 1 to 4. Multiple stitch formations can also be used (e.g., following an x+y/m+n/etc. configuration). The resulting weft-inserted warp knit fabric possesses superior dimensional stability and internal geometry, while maintaining the tearability requisite for a hand-tearable tape product.

  • Publication number: 20050233656
    Abstract: The present disclosure relates to cementitious articles that are reinforced with a fabric made at least partially of high modulus polyolefin monofilament fibers. Preferably, the polypropylene monofilament yarns have a 3% secant modulus of elasticity of at least 100 g/denier. The high modulus polypropylene fabric has an intrinsic resistance to the alkaline conditions present in a cementitious composite, as well as a low elongation at break. The high modulus polypropylene may contain a nucleating agent to facilitate the process of obtaining desired draw ratio.
