Abstract
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.
Claims22
A woven fabric comprising an alternating pattern containing first weave zones and partial float weave zones, wherein the woven fabric comprises:
- a plurality warp yarns arranged into groupings of warp yarns, wherein each grouping contains between 2 and 10 warp yarns;
- and,
- a plurality of picks of weft yarns;
- wherein in each first weave zone the picks of weft yarns comprise a repeating first weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn, wherein within the first weave zones each warp yarn passes successively over and under alternating picks of weft yarns forming a plain weave,
- wherein in each partial float zone the picks of weft yarns within the partial float weave zone comprise a repeating second weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn,
- wherein 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 single-inserted multifilament weft yarn in at least a portion of weft pattern repeats, and wherein outside of the floats the non-floating warp yarns pass successively over and under alternating picks of weft yarns.
An innerduct for a cable comprising one or more strip-shaped lengths of woven textile fabric configured to create a flexible, longitudinal compartment for enveloping a cable, wherein the woven fabric comprises a plurality warp yarns and a plurality of picks of weft yarns, wherein the weft yarns comprise a repeating first weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn, wherein the woven fabric comprises an alternating pattern containing first weave zones and partial float weave zones,
- wherein in the first weave zones, the warp yarns pass successively over and under each adjacent weft yarn forming a plain weave,
- wherein in the partial float zones, at least a portion of the warp yarns float over some adjacent weft yarns including floating over at least one single-inserted multifilament weft yarn in at least a portion of first weft pattern repeats, and wherein outside of the floats the non-floating warp yarns pass successively over and under alternating picks of weft yarns.
An innerduct for a cable comprising one or more strip-shaped lengths of woven textile fabric configured to create a flexible, longitudinal compartment for enveloping a cable, wherein the textile fabric comprises:
- a plurality warp yarns arranged into groupings of warp yarns, wherein each grouping contains between 2 and 10 warp yarns;
- and,
- a plurality of picks of weft yarns;
- wherein in each first weave zone the picks of weft yarns comprise a repeating first weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn, wherein within the first weave zones each warp yarn passes successively over and under alternating picks of weft yarns forming a plain weave,
- wherein in each partial float zone the picks of weft yarns within the partial float weave zone comprise a repeating second weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn,
- wherein 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 single-inserted multifilament weft yarn in at least a portion of weft pattern repeats, and wherein outside of the floats the non-floating warp yarns pass successively over and under alternating picks of weft yarns, and wherein the repeating pattern of the zones in the woven fabric consists of an alternating pattern of first weave zones and partial float weave zones.
An apparatus comprising:
- a conduit;
- an innerduct positioned inside the conduit, the innerduct comprising at least one strip-shaped panel of woven textile material folded about a centrally located longitudinal axis and adjoined along the longitudinal edge portions to define at least one longitudinal channel that is configured to enclose and carry a cable, wherein said woven textile material comprises:
- a plurality warp yarns arranged into groupings of warp yarns, wherein each grouping contains between 2 and 10 warp yarns;
- and,
- a plurality of picks of weft yarns;
- wherein in each first weave zone the picks of weft yarns comprise a repeating first weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn, wherein within the first weave zones each warp yarn passes successively over and under alternating picks of weft yarns forming a plain weave,
- wherein in each partial float zone the picks of weft yarns within the partial float weave zone comprise a repeating second weft pattern of at least one monofilament yarn and at least one single-inserted multifilament yarn,
- wherein 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 single-inserted multifilament weft yarn in at least a portion of weft pattern repeats, and wherein outside of the floats the non-floating warp yarns pass successively over and under alternating picks of weft yarns.
