(also filling), yarns or threads in a fabric running perpendicular to and interwoven with the warp yarns or threads. Weft yarns are interwoven with warp yarns during shedding and are then beaten up. Material of lower quality is often used for weft yarns, because the weft is subjected to less tension during weaving than the warp. In tulle, curtain fabrics, and knitwear, yarns running in the filling direction are also called weft yarns.
