Abstract
The invention discloses a woven fabric weft curve fabric and a weaving method. By means of a device capable of controlling the warp supply amount of part of warp, by changing the warp supply amount of warp, the density is changed, and therefore bending deformation happens to weft, and the curve effect is embodied on the cloth surface. By changing the weft density, the traditional ground horizontal flat effect is changed on the aspect of the fabric array of weft, and the curve appearance of weft is generated. By changing the weft density, the beautiful dual-curve pattern can be generated by means of colorful threads, and the variety level of the woven fabric is improved.
