  • Patent number: 9222206
    Abstract: A nonwoven fabric facilitating permeation of loose passage. A nonwoven fabric is formed of short fibers of thermoplastic synthetic resin fused together. The nonwoven fabric is formed on a top side thereof with ridges and troughs undulating in a width direction and extending in parallel to one another in a length direction. When the nonwoven fabric is placed on a horizontal plane with the back side put in contact with the horizontal plate, highly void regions are formed between the back side and the horizontal plane. In the vicinity of apices of the respective ridges, the short fibers slope down so as to extend in a thickness direction of the nonwoven fabric.

    Abstract: Absorbable polyester fibers, braids, and surgical meshes with prolonged strength retention have been developed. These devices are preferably derived from biocompatible copolymers or homopolymers of 4-hydroxybutyrate. These devices provide a wider range of in vivo strength retention properties than are currently available, and could offer additional benefits such as anti-adhesion properties, reduced risks of infection or other post-operative problems resulting from absorption and eventual elimination of the device, and competitive cost. The devices may also be particularly suitable for use in pediatric populations where their absorption should not hinder growth, and provide in all patient populations wound healing with long-term mechanical stability. The devices may additionally be combined with autologous, allogenic and/or xenogenic tissues to provide implants with improved mechanical, biological and handling properties.

  • Patent number: 7772137
    Abstract: Breathable materials comprise a low-elongation fabric layer and a microporous coating thereon. The microporous coating comprises a crystalline polymer composition and a filler. The materials are suitable for use in various applications including housewrap and other construction embodiments. Methods of making a breathable material comprise extrusion coating a low-elongation fabric layer with a composition comprising a crystalline polymer composition and a filler to form a coating on the low-elongation fabric layer, and incrementally stretching the coated nonwoven layer to render the coating microporous.

  • Patent number: 7772136
    Abstract: A roofing underlayment comprises a reinforcing layer, which is extrusion coated on at least one side with an anti-slip coating layer. Preferably, the reinforcing layer comprises a woven polyethylene or polypropylene scrim. The anti-slip coating layer comprises a compound based on a styrene and ethylene/butylene-styrene, S-E/B-S, block copolymer, such as the compound sold under the trademark KRATON® MD6649. The anti-slip coating layer is low in cost and helps prevent water from penetrating the primary roofing material. In addition, the anti-slip coating layer provides an improved anti-skid surface upon which an individual may safely walk.

  • Patent number: 7625827
    Abstract: A corrosion-resistant lath is provided for use in exterior finishing systems, such as stucco systems and exterior insulation and finish systems (“EIFS”). The lath includes in a first embodiment an open, woven fabric comprising weft and warp yarns containing non-metallic fibers, such as glass fibers. A portion of the weft yarns are undulated, resulting in an increased thickness for the fabric. The fabric is coated with a polymeric resin for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making an exterior finish system and building wall including an exterior finish system using such a lath.

  • Publication number: 20090269564
    Abstract: By the extrusion method, (position 1) polyethylene yarns are produced (position 2). These yarns are cooled in a cold water container (position 3). Following that and after having been pre-stretched (position 4), the yarns come into a heating oven (position 5), where they are drawn by shafts (position 6). The monofilament that has been created by the method is then coiled in bobbins (position 8) through an appropriate coiling system (position 9). Following that, the monofilament bobbins are placed on the Raschel knitting machine and are knitted together with polyethylene yarns in latticed fabric. The final product shall be a net utilized for the palletization of various materials. This net has high elasticity, extensibility and breaking resistance.
