Abstract

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.

First claim

What is claimed is:

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

2. The woven fabric of claim 1 , 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.

3. The woven fabric of claim 1 , wherein the repeating pattern of zones comprises first weave zones, partial float weave zones, and second weave zones.

4. 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, at least one multiple-inserted multifilament yarn, and optionally at least one single-inserted multifilament yarn,
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, at least one multiple-inserted multifilament yarn, and optionally 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 multiple-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 weft yarns in both the first weave zone and the partial float zone comprise a repeating pattern of at least one monofilament yarn, at least one double-inserted multifilament yarn, and optionally at least one single-inserted multifilament yarn throughout the entire fabric.

5. The woven fabric of claim 1 , wherein the weft yarns in both the first weave zone and the partial float zone comprise a repeating pattern consisting of one monofilament yarn, one double-inserted multifilament yarn, and one single-inserted multifilament yarn.

6. 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, at least one multiple-inserted multifilament yarn, and optionally at least one single-inserted multifilament yarn,
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, at least one multiple-inserted multifilament yarn, and optionally 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 multiple-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 warp yarns are monofilament yarns.

7. 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, at least one multiple-inserted multifilament yarn, and optionally at least one single-inserted multifilament yarn,
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, at least one multiple-inserted multifilament yarn, and optionally 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 multiple-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 at least a portion of the yarns in the woven fabric comprise a UV stabilizer.

8. The woven fabric of claim 1 , wherein between 1 warp yarn and half of the warp yarns within each warp grouping float over 3 weft yarns including floating over at least one multiple-inserted multifilament weft yarn in each weft pattern repeat.

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