Abstract:

In order to solve peoblems on the weaving of weft curved fabrics, the forming technology for weft weave curved fabrics were developed by changing the mechanical structure, adjustment the combination of fabric structures and using elastic beat-up; or by changing straight line beat-up state to produce weft curves; or by modifying partial the let-off rate to achieve weft bending, et al. A variety of devices were developed one after another to meet the requirements of different weaving machine models. For instance, for weaving machines suitable for employing large jacquards, the elastic free reed was designed; and for weaving machines suitable for employing dobby, the double-curved three-dimensional surfaced reed was designed; and for the universal model adapting to those including air-jet loom the devices to control, the warp let-off was designed to produce latitudinal curve fabrics and weft directional curve fabrics, so that the fabric is more unique and novel in style, and is more vivid and rich in appearance by the fashion design of colors and patterns.
