METHOD FOR FORMATION OF FABRIC WITH WARP VARYING DENSITY IN LONGITUDINAL DIRECTION ON LOOM

摘要

FIELD: textile industry, weaving. SUBSTANCE: method for formation of fabric with warp varying density in longitudinal direction on loom includes tensioning of warp threads, their releasing, insertion and beating-up of weft, withdrawal of formed fabric, shedding by separation of warp threads into two systems, their moving in vertical plane and moving of groups of the second system of warp threads in horizontal plane to respective groups of the first system of warp threads. During shedding, in lifting and lowering of warp, weft intercrossings of weaves of derivatives from plain weave within the repeat of weft fabric pattern. EFFECT: reduced attrition of warp by loom guide members due to exclusion in operation of shedding of additional moving in horizontal plane, the groups of the second system of warp in zone of reed-heald that results in decrease of breakage of warp threads by 31.8%; higher efficiency. 3 dwg
