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 and 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.
Claims14
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 an alternating pattern containing first weave zones and partial float weave zones, 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 within each first weave zone each warp yarn passes successively over and under each adjacent weft yarn forming a plain weave,
- wherein within each partial float zone only a portion of the warp yarns within at least a portion of the warp groupings float over 3 weft yarns 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 an alternating pattern containing first weave zones and partial float weave zones, 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, wherein the warp yarns are monofilament yarns;
- and,
- a plurality of picks of weft yarns, wherein the ratio of picks in the first weave zone to picks in the partial float zone is between about 1:2 to 2:1;
- wherein within each first weave zone each warp yarn passes successively over and under each adjacent weft yarn forming a plain weave,
- wherein within each partial float zone only a portion of the warp yarns within at least a portion of the warp groupings float over 3 weft yarns and wherein outside of the floats the non-floating warp yarns pass successively over and under alternating picks of weft yarns.
