Terry Towelling Shedding and Pile Formation
topic
Terry towelling loom shedding uses a three-pick terry cycle where two picks are woven at a temporary fell position distant from the cloth fell, then the third pick beats up all three picks to the fabric fell, with the pile warp held under low tension allowing it to buckle into pile loops of defined height determined by the distance between the temporary and actual fell positions, controlled by a special back rest mechanism.
Role
Produces the pile loop structure of terry towelling by exploiting the differential tension and beat-up timing that allows the pile warp to form loops of controlled height at each terry cycle completion, with pile height, loop density, and pile yarn tension management being the key process parameters that determine the absorbency, softness, and hand characteristics of towelling and robe fabrics.
