  • Patent number: 9730429
    Abstract: A flexible abrasion resistant omnidirectionally reflective retractable pet leash has an omnidirectionally reflective pet leash housed within a retractable housing device. The omnidirectionally reflective pet leash reflects an incoming light beam back in the same direction as it was emanated. The reflected light beam provides accurate illumination of the pet leash and the location of the pet during dusk or nighttime hours. This retractable pet leash is created by surrounding a central braided rope of nylon or polyethylene fibers with a cylindrically braided reflective sleeve. The braided reflective sleeve is composed of braided narrow width reflective strips each comprising a plurality of reflective threads worked together to form a weave. Due to the braided weave of the reflective threads and the arrangement of the microscopic reflectors light incident thereon from virtually any angle is reflected back to its source.

    Abstract: A composite hemp and cotton yarn is formed by blending hemp fibers with cotton fibers which have been regenerated from waste cotton material such as trimmings and cuttings from the apparel manufacturing industry. The fibers are cleaned and blended, then carded to align the fibers into strands. Depending on the size and texture of the desired yarn, the fibers are stretched and drawn into slivers prior to spinning to join the fibers together. The hemp fibers are up to three time longer than the regenerated cotton fibers, so that the hemp fibers overlap and braid onto the regenerated cotton fibers during spinning. The resultant yarn is stronger and more absorbent than yarns made solely out of regenerated cotton fibers or a blend of cotton and acrylic or cotton and polyester fibers.

  • Patent number: 7461500
    Abstract: A twisted rope for use in rigging systems that includes a differently colored yarn positioned within at least one strand. As the rope is worn, the differently colored yarn will become exposed, thereby serving as a visual indicator of wear to the rope. A plastic strip printed with identifying information about the rope is placed within the fibers of the rope during manufacture may also be positioned with a strand of the twisted rope. A user can simply unravel one end of the rope and read the information printed on the strip to determine, for example, the composition of the rope, when the rope was manufactured, the load-bearing characteristics of the rope, and who was the rope manufacturer.

  • Patent number: 7309667
    Abstract: A fabric includes mutually transverse thread systems, with at least one of the thread systems including a differential shrinkage yarn C. The shrinkage yarn C has at least one effect component A that irreversibly elongates itself upon heat treatment, and at least one shrinkage component B that shortens itself upon heat treatment. The components A and B are bound together by nodes, wherein the number (y) of nodes per meter in the yarn C is predetermined as a function of the yarn count (x) of the transverse thread system so that the number (y) of nodes exceeds a minimum value and increases proportionally above the minimum value as a function of the yarn count (x).

  • Patent number: 7291389
    Abstract: Articles, particularly fibers, whose shape is dependent on temperature. The articles have a first component composed of a sharply-melting crystalline polymer and an overlapping second component. As the crystalline polymer is cooled through its melting range, the volume of the first component increases much more rapidly than the volume of the second component. As a result, the shape of the article changes. Such fibers can be incorporated into fibrous articles having temperature-dependent thermal insulation properties.

  • Patent number: 7288306
    Abstract: A textile substrate is made from two or more strands of yarn that are twisted together using a very low variable twist level. The amount of slight twist and variation in the twist are effective to give the finished carpet made from the textile substrate a uniform appearance in spite of any slight variations in one or more characteristics of the yarn. The textile substrate, by using such a low variable twist level, can avoid streaks in the carpet, for instance, caused by variations in yarn lots and the like.

  • Patent number: 7189295
    Abstract: Yarn suitable for tufting comprises a base fiber ring spun or wrap spun with a second fiber at least partially comprising a heat-activated adhesive material such that the yarn includes from 0.1 to 12, preferably 0.25 to 10, weight percent adhesive material having a melting point within the range of 105° to 190° C., more preferably 165° to 190° C. A preferred base fiber is a synthetic staple fiber bundle. A preferred wrapping or insert fiber comprises copolyamide material, including ternary copolyamides of the 6/66/12 type. When the yarn is twist set by conventional processes and then tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.

  • Patent number: 7138167
    Abstract: A preform for a fiber-reinforced composite material including a bent portion along a curved line for bending, a flange portion corresponding to an outer circumferential portion, and a semi-cylindrical portion formed by bending an inner circumferential portion along the curved line for bending located in a flat plane or a curved plane region. The preform is formed from a precursor having a predetermined extension. The outer circumferential portion corresponds to a first region where a first plurality of reinforced fibers is partially disposed in parallel along the curved line for bending. The inner circumferential portion corresponds to a second region constituted solely of a second plurality of reinforced fibers disposed throughout the entire area, so as to intersect the first plurality of reinforced fibers at a predetermined angle in the first region.
