Research on beating-up process and weaving variables

Aiming at the determination of weaving variables such as weaving resistance,through force analysis of weaving weft in beating-up period,tension relation between the front and back warps of weaving weft is given,and the expressions of elastic resistance,frictional resistance and total resistance exerted on weaving weft by single warp are deduced.Based on weaving situation of modern loom and mechanical properties of fabric and warp,force-deformation equations of fabric and warp are established.Moreover,formulae of warp tension,weaving resistance and warp extension,which are expressed in term of the position of weaving weft,are obtained by solving force-deformation equations and warp tension relation.Finally,variations of weaving variables,such as warp tension and weaving resistance,with the position of weaving weft are calculated and analyzed by use of previous experiment data,and the results show that the formulae are quite accurate.
