  • Patent number: 9982367
    Abstract: A method of making a spun-bond nonwoven fabric of thermoplastic filaments has the steps of first spinning the thermoplastic filaments, then cooling the spun filaments, and then conducting the cooled and spun filaments in a travel direction through a stretcher with primary air such that the primary air exits a downstream end of the stretcher with the filaments at a predetermined primary air volume/flow VP. The filaments and substantially all of the primary air are passed together as a flow from the downstream end of the stretcher into a diffuser. Secondary air is introduced into the flow at a secondary air volume/flow VS such that a ratio VP/VS of the primary rate VP to the secondary rate is equal to at least 4.5 and the primary and secondary air flow with the filaments in the travel direction through the diffuser.

A polymer membrane and/or a textile may be laminated to the woven fabric to produce a laminated article. The ePTFE woven fabric simultaneously possesses high moisture vapor transmission (highly breathable) and high water entry pressure (water resistant). The woven fabric is quiet, soft, and drapable, making it especially suitable for use in garments, gloves and footwear applications. Treatments may be provided to the surface of the ePTFE fiber and/or the woven fabric to impart one or more desired functionality, such as, for example, oleophobicity.

  • Publication number: 20110290397
    Abstract: A steel cord (10) adapted for the reinforcement of rubber products, the steel cord comprises a core (12) and a layer of filaments (14) with round cross-sections twisted around the core (12). The core (12) comprises a flat wire at a waveform, which lies in the plane of the flat wire. The wire is obtainable by first crimping a round wire and thereafter flattening the crimped wire. The filaments of the layer do not substantially contact each other to make spaces between each other to insure adequate rubber penetration into the cords. The steel cord has improvements on elongation at break.

  • Publication number: 20110086224
    Abstract: A planar sheet comprises a plurality of polyamide yarns having a yarn modulus of from 3.7 to 6.8 N/dtex, an elongation to break of from 2.9 to 4.7% and a denier of from 130 to 15,000 and a plurality of steel wires wherein the steel wire is provided with a first crimp and a second crimp, the first crimp lying in a plane that is substantially different from the plane of the second crimp. The first and second crimp pitches and amplitudes of the steel wire are such that, when the steel wire and polyamide yarns are combined, the elongation to break of the wire is similar to that of the polyamide yarn. The wires and yarns are arranged such that they are oriented parallel to each other within the planar sheet. The sheet has utility in the construction of elastomeric components for tires and belts.

  • Patent number: 7862891
    Abstract: The present invention includes a nontwisted composite tether comprising one or more composite rods encased in a jacket and a method for manufacturing same. A portion of the rods may be bundled into one or more strands, provided however that the rods comprising the strands are not twisted into twisted strands in the assembled nontwisted tether. Such untwisted strands, if any, additionally are not twisted relative to each other. Temporary and/or permanent buoyancy may be to the tether. The present invention includes methods for preparing, transporting, and installing a composite tether on a floating platform. The tether, preferably assembled at a waterfront, is launched into the water and towed to an offshore installation site, where the tether is upended and connected via a bottom end connector on the tether to an anchor foundation in the seabed and connected a top end connector on the tether to the floating platform.
