  • Patent number: 8679292
    Abstract: A method is conceived for producing hydrophobic lignocellulosics based on the graft copolymerisation of vinyl-type monomers onto the lignocellulosic backbone initiated by a redox couple initiator in aqueous medium. The green modification process can be carried out on any lignocellulosic material, for example, chemical, chemi-thermomechanical or thermo-mechanical pulps, bleached or unbleached. The technology disclosed in this invention yields individual lignocellulosic entities, for instance, hydrophobic pulp fibers, that can be used in combination with other fibers or polymers to produce nonwoven fibrous materials or composites. A significant aspect of the invention is that the modified lignocellulosic material possesses an efficient hydrophobic barrier and minimum interfacial energy to generate optimum adhesion when introduced to polymer resins.

  • Publication number: 20100098944
    Abstract: In a method of producing a moulded product, fibre such as carbon fibre is supplied to a robot delivery head where it is cut into shorter lengths and delivered to a moulding tool in a desired orientation and in a desired number of layers to achieve a desired thickness and strength. Resin is then applied to the aligned fibres and cured to form the product. Alignment or substantial alignment of fibre is maintained by applying vacuum to the mould, by electrostatic means, or by coating the fibre with resin prior to application to the moulding tool and heating the moulding tool surface, or by coating or impregnating the fibre with a ferric powder and magnetizing the moulding tool, or by applying a mist layer of epoxy in front of the shortened lengths of fibres. Fibre lengths and deposition rates are varied as required. The method facilitates fully automated production reducing process time and component costs. The invention also comprises a corresponding moulded product.

  • Publication number: 20090197080
    Abstract: Disclosed is a method and device for creating three dimensional (3D) self-crimping fluoropolymer(s) and perfluoropolymer(s) filaments via extrusion through a spinneret plate orifice with a hole and elliptical gap and using die swell to close the elliptical gap in the filament forming a seam causing uneven stresses in the longitudinal length of the filament while cooling thereby causing the filament to self-crimp toward the seam.

  • Patent number: 7560142
    Abstract: A fiber containing a bound active material, such as a metal oxide, under 20 microns in diameter. The inventive fiber is formed through the mixing of the fibers with a cationic or anionic polymer in one tank, the active material with a cationic or anionic polymer in a second tank, the opposite zeta potential of that used with the active material, and then mixing the active material/polymer and fiber/polymer blends together.

  • Publication number: 20090025359
    Abstract: Input fibers to be used for the manufacture of textile components are cut to a proper length [113]. The fibers are metallized [115] with silver and copper. The metallized fibers are opened [121] and blended [123] with other fibers. The blended fibers are preferably opened again [125]. Then the blended fibers are oriented [127] and drawn [129] into a sliver. Roving [140] may be applied to the sliver to condense the fibers. The length of the fibers, the denier of the fibers, the amount of metal coating and composition of the metal coating are selected to provide an optimum amount of metal ion discharge to have the proper antimicrobial properties, while optimizing wound healing properties, and minimizing manufacturing costs.

  • Patent number: 7410650
    Abstract: A method of fabricating nano-silver fibers is provided. An organic solution of a dispersant is prepared. Then, a silver salt and a reductant are added into the organic solution. The organic solution is stirred to let the silver salt and the reductant react to form silver nanoparticles dispersed in the organic solution uniformly. Next, a spinnable polymer resin is dissolved in the organic solution to form a spinning solution. A wet spinning method is performed to let the spinning solution form nano-silver fibers.
