Virtual Testing Method and Its Analysis of the Warp Let-off Motion on Water-jet Loom

Aim at the start mark of a water-jet loom during weaving,a virtual testing method to test the warp Let-off motion was introduced in this paper.The apparatus can accurately test the characteristic curve of the warp let-off motion during weaving and calculate the warp let-off value and the histogram per pick.Furthermore,based on testing results,the let-off mechanism of the water-jet loom was analyzed and the improving method was also introduced.
