Weft take-up distribution over the width of woven fabrics manufactured with the use of jet looms

An investigation of weft take-up uniformity over the width of decorative woven fabrics for drapery manufactured with the use of a NISSAN LW 551 hydraulic loom and a PICANOL OMNI pneumatic loom is presented. The influence of the loom picking mechanism settings on the value and the distribution of weft take-up in woven fabrics has been estimated. The authors state that to achieve as good a weft take-up distribution as possible and thereby a uniform woven fabric structure, with the use of a pneumatic loom, the best solution is to use high air pressure in the crimp removal jet or low air pressure in the subnozzles; with the use of a hydraulic loom the most advantageous solution is to set a great water portion volume.
