  • Patent number: 10640893
    Abstract: Disclosed are technical fibers and yarns made with partially aromatic polyamides and non-halogenated flame retardant additives. Fabrics made from such fibers and yarns demonstrate superior flame retardancy over traditional flame retardant nylon 6,6 fabrics. Further, the disclosed fibers and yarns, when blended with other flame retardant fibers, do not demonstrate the dangerous “scaffolding effect” common with flame retardant nylon 6,6 blended fabrics.

  • Patent number: 10087574
    Abstract: Markings visible by automatic optically guided cutting equipment are provided in a fabric such as a double layer fabric for one-piece-woven air bags by groups of black marker weft yarns which contrast with the other (white) weft yarns and warp yarns. The marker weft yarns emerge onto the upper face of the fabric only in predetermined marker areas spaced apart in the warp direction by other white weft yarns to afford optically identifiable markings spaced apart along said weft yarns and spaced apart along the direction of the warp yarns. The arrangement avoids the need for black warp yarns and thus avoids the inconveniences and loom down-time associated with required alterations to the locations of such optically detectable marker areas in the fabric web.
