Recent developments have allowed air-jet weaving machines to handle filling yams with thickness variations, thus joining the solid shuttleless weaving systems in producing fabrics from novelty filling yarns. The increasing popularity of shuttleless weaving technologies and their ability to weave such filling yams has created a need to expand the weavability limit theory to fabrics constructed on shuttleless weaving machines. In this paper, theoretical weavability limit relationships of such fabrics are derived in terms of warp and filling cover factors, warp and filling yam characteristics, and the distribution of thick and thin places of filling yam over the fabric surface.
