    摘要: A flexible innerduct having a seam region and a chamber region, where the innerduct structure contains at least two flexible, longitudinal chambers, each chamber designed for enveloping at least one cable. The flexible innerduct comprises at least one strip of textile material, where each strip of textile material comprises a first edge and a second edge and extends in the longitudinal direction. All of the first and second edges of the strips are located in the seam region. Each strip of textile material extends outwards from the seam region, folds about a fold axis located in the chamber margin region and returns to the seam region forming a chamber. The chamber length, defined to be the distance between the seam region and the fold axis of the chamber, is different between at least two of the flexible, longitudinal chambers.

    摘要: A wound dressing comprising a multi-ply knit fabric containing a first knit ply, a second knit ply, and at least one silver ion-containing compound. The first knit ply contains a plurality of first yarns and forms the upper surface of the fabric. The second knit ply contains a plurality of polytetrafluoroethylene (PTFE) yarns, where the PTFE yarns have a transmission in the IR region of 8-10 µm at least about 40%, a thermal conductivity of at least about 0.2 W/(m.K), and forms the lower surface of the fabric. The first and second ply are integrated through combined portions formed by interlacing first yarns among the PTFE yarns of the second knit ply, interlacing PTFE yarns among the first yarns of the first knit ply, or interlacing a plurality of third yarns among the first yarns and the PTFE.

    摘要: A strengthened polyethylene tubular member, where the polyethylene tubular member has an outer surface, a circumference, a wall thickness, an area to be strengthened, and the outer surface of the polyethylene tubular member contains polyethylene. The strengthened polyethylene tubular member contains a fabric layer wrapped around the circumference of the tubular member at least two full rotations and covering the area to be strengthened. The fabric layer contains a plurality of interwoven tape elements with a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. The tape elements within the fabric layer are bonded together and the tape elements adjacent the tubular member are bonded to the tubular member.
