Staple Length Fiber Patents (Class 428/359)
  • Patent number: 10239788
    Abstract: A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and means for molecular scale healing has the ability to repair structural defects by a bio-mimetic, close-then-heal process. The shape memory polymer serves to bring surfaces of a structural defect into proximity, after which the healing means moves into the defect and provides molecular scale healing. The means for molecular scale healing can be a thermoplastic, such as fibers, particles or spheres, which are heated to or above the thermoplastic's melting point, and then the composition is cooled below that melting temperature. The compositions can not only close macroscopic defects, but they can also do so repeatedly even if damage recurs in a previously healed/repaired area.

  • Publication number: 20120321832
    Abstract: An extruded oriented thermo-plastic polymeric element for industrial textiles, and textiles comprising polymeric elements. The polymeric elements are constructed of a material selected from yarn material, fiber material and film, and comprise a thermoplastic polymer, and at least one dry lubricant, selected from molybdenum disulphide, tungsten disulphide, boron nitride, and a soft metal, the dry lubricant comprising particulate matter having an average particle size between about 0.05? and about 100?, and present in the polymeric element in an amount from between about 0.1% and about 10% parts by weight, based on a total weight of the polymeric element. The polymeric elements can be used as yarns in woven and non woven textiles, and as seaming elements. The polymeric elements provide increased abrasion resistance in industrial textiles, and reduced co-efficient of friction.
