Method for weaving pile fabrics and pile fabric with shadow cut pile zones

摘要

In this method for simultaneously weaving two pile fabrics (C1, C2) with shadow cut pile zones on a face-to-face weaving machine, an upper backing fabric (F1) and a lower backing fabric (F2) are woven one above the other with at least one filling warp yarns (f1, f2), at least one binding warp yarn (b1, b2), weft yarns (Wi, Wb) inserted in successive weft insertion cycles (P1-P32) between binding warp yarns and filling warp yarns, the weft yarns comprising inner weft yarns (Wi) inserted on a pile side of the filling warp yarns and back weft yarns (Wb) inserted on a back side of the filling warp yarns, opposite to the piles of the fabric. Patterning pile yarns (V) are interlaced in the upper backing fabric (F1) and in the lower backing fabric (F2), each patterning pile yarn turning externally around an inner and a back weft yarns (Wi, Wb) in each backing fabric. At least one patterning pile yarn (V) follows a path where, in a first series of weft insertion cycles (P1-P16) and at least in a first backing fabric (F1, F2), the patterning pile yarn (V) turns externally around an inner weft yarn (Wi) before it turns externally around a consecutive back weft yarn (Wb) and, in a second series of weft insertion cycles (P20-P32) and at least in the first backing fabric, the patterning pile yarn (V) turns externally around a back weft yarn (Wb) before it turns externally around a consecutive inner weft yarn (Wi).
