ABSTRACT:
A tubular fabric for use as a carcass for power transmission and conveyor belts. A plurality of longitudinal warp yarns and a plurality of transverse weft yarns are interwoven in a warp weave wherein the transverse weft yarns form adjacent pairs having upper yarns and lower yarns. The longitudinal warp yarns pass above a first upper yarn of a pair of transverse weft yarns, between a second upper yarn and a second lower yarn of a second pair of transverse weft yarns adjacent the first pair, below a third lower yarn of a third pair of transverse weft yarns adjacent the second pair and between a fourth upper yarn and a fourth lower yarn of a fourth pair of transverse weft yarns adjacent the third pair.
From a planar view of the surface of the tubular fabric, the yarns are substantially perpendicular and have a weft weave which has the same configuration as the warp weave. At recurrent intervals, the longitudinal warp yarns and transverse weft yarns pass over, between, under and between the transverse weft yarns and longitudinal warp yarns, respectively. The symmetrical two-ply construction results in each warp yarn and weft yarn appearing on the inner and outer surface of the tubular fabric. This also results in the yarns being arranged in a one-third broken twill order wherein the warp and weft yarns are arranged in a 4-end satin order. As described above, the fabric is two-ply and it can also be woven in three and four-ply layers by interweaving a layer of the tubular fabric with a layer of another tubular fabric.
