    摘要: A flexible innerduct structure having a first margin region, a second margin region, and a middle region, where the middle region is located between the first and second margin regions. The innerduct structure contains at least two flexible, longitudinal chambers, with each chamber being designed for enveloping at least one cable.
    The flexible innerduct structure contains at least one strip-shaped textile, each strip containing a first side and a second edge and extending in the longitudinal direction. All first and second edges of the strips are located in the middle region and each strip-shaped textile extends outwards from the middle region, folds about a fold axis located in either the first or second margin region and returns to the middle region. At least one strip extends from the first to the second margin region and the strips are attached together in the middle region.

    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: An innerduct for a cable containing one or more strip-shaped lengths of woven textile fabric configured to create a flexible, longitudinal compartment for enveloping a cable. The woven fabric comprises a plurality warp yarns and a plurality of picks of weft yarns, the weft yarns contain a repeating first weft pattern of at least one monofilament yarn and optionally at least one single-inserted multifilament yarn. The woven fabric contains an alternating pattern containing first weave zones and partial float weave zones. The warp yarns in the first weave zone pass successively over and under each adjacent weft yarn and at least a portion of the warp yarns in the partial float zone float over some adjacent weft yarns.

    摘要: A woven fabric containing an alternating pattern containing first weave zones and partial float weave zones. The woven fabric contains a plurality warp yarns arranged into groupings of warp yarns. In each first weave zone, the picks of weft yarns contain a repeating first weft pattern. In each partial float zone, the picks of weft yarns within the partial float weave zone contain a repeating second weft pattern of at least one monofilament yarn and at least one multiple-inserted multifilament yarn. Within the partial float zone, only a portion of the warp yarns within at least a portion of the warp groupings float over 3 weft yarns including floating over at least one multiple-inserted multifilament weft yarn in at least a portion of weft pattern repeats. An innerduct structure containing the woven fabric is also described.

    摘要: A flexible innerduct structure having a first edge, a second edge, a first margin region, a second margin region, and a middle region. The middle region is located between the first and second margin regions. The innerduct structure comprises at least two flexible longitudinal tubes, each longitudinal tube forming two chambers. Each chamber is designed for enveloping at least one cable, where at least one of the longitudinal tubes extends from the first margin region to the second margin region, and wherein the tubes are attached together at an attachment in the middle region.
