  • Solid-color weave pattern belt
    Patent number: 5054524

The weave comprises a 2/2 twill weave having four warp threading phases with warp threading arrangement units selected from three kinds of units formed by omitting one to three warp threading phases from the four warp threading phases. A plurality of at least one warp threading arrangement units are successively adjacent to each other, thereby forming an uneven weave pattern of wefts substantially hidden behind the warps on the surface of the belt.
