20080253712 | Optical fiber substrate useful as a sensor or illumination device component - 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. | 10-16-2008 |
20090126411 | Textile-reinforced composites with high tear strength - The present disclosure relates to a reinforcing textile material that comprises a weft-inserted warp knit fabric, in which the warp yarns are configured in a pattern having a majority of successive flat stitches that are used in conjunction with a minority of subsequent successive round stitches. The warp yarn configuration may be represented by the expression x+y, where x is the number of successive needle positions in which a warp yarn is positioned in a flat stitch arrangement and y is the number of subsequent successive needle positions in which the same warp yarn is positioned in a round stitch arrangement. The present weft-inserted warp knit fabrics possess improved dimensional stability, high tensile strength, high tear strength, and a relatively smooth surface, making them well-suited for use as reinforcements in roofing membranes, signs, banners, tents, and the like. | 05-21-2009 |
20100218878 | Treated Textile Substrate and Method For Making A Textile Substrate - 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. | 09-02-2010 |
20130112625 | CONSOLIDATED NANOFIBER NONWOVENS AND CONSOLIDATED NANOFIBER NONWOVEN COMPOSITES CONTAINING ROPED FIBER BUNDLES - A consolidated nanofiber nonwoven comprising a plurality of roped fiber bundles having a length axis. The roped fiber bundles comprise a plurality of nanofibers having a median diameter of less than one micrometer, where at least 50% by number of the nanofibers are oriented within 45 degrees of the length axis of the roped fiber bundles. The nanofibers within the same roped fiber bundle are entangled together. The roped fiber bundles are randomly oriented within the nanofiber nonwoven and are entangled with other roped fiber bundles within the nanofiber nonwoven. At least a portion of the nanofibers are entangled with and adhered to other nanofibers within the same roped fiber bundle and at least a portion of the roped fiber bundles are entangled with and adhered to other roped fiber bundles within the consolidated nanofiber nonwoven. | 05-09-2013 |
20130115837 | NANOFIBER NONWOVENS AND NANOFIBER NONWOVEN COMPOSITES CONTAINING ROPED FIBER BUNDLES - A nanofiber nonwoven comprising a plurality of roped fiber bundles having a length axis. The roped fiber bundles comprise a plurality of nanofibers having a median diameter of less than one micrometer, where at least 50% by number of the nanofibers are oriented within 45 degrees of the length axis of the roped fiber bundles. The nanofibers within the same roped fiber bundle are entangled together. The roped fiber bundles are randomly oriented within the nanofiber nonwoven and are entangled with other roped fiber bundles within the nanofiber nonwoven. | 05-09-2013 |
