Application of bundle-filling technology on weaving modified warp-rib fabric

To improve the filling insertion rate during weaving modified warp-rib fabric with air-jet looms,this paper discussed the new methods and process based on the analysis of the features of modified warp-rib′s structures.The research indicates that while applying bundle-filling technology on air-jet looms with functions of multiple-color filling,electronic take-up and let-off,and modified pick count,the plain-weave cam shedding motion can be used to weave modified warp-rib fabric.During every opening,different numbers of weft should be inserted in preset orders.According to the numbers of weft that are inserted,the take-up and let-off devices send out different lengths of warp,and guide the relevant length of fabric away from the cloth-fell to realize the weaving of modified warp-rib. The practice has proven that weaving modified warp-rip with bundle-filling technology can increase air-jet looms′ operating speed,filling insertion rate and production,while reducing cost,thus improving the economic benefit of enterprises.
