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, at least one multiple-inserted multifilament 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.
Claims6
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, at least one multiple-inserted multifilament yarn, and optionally 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 multiple-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.
