3D-Weaving: Theory and Practice

The development of the first-ever dual-directional shedding system has now empirically validated the findings and the technical characterization of the 3D-weaving process presented about three years ago, which hypothesized that such an operation alone forms the basis for defining and carrying out the 3D-weaving process. Through this shedding operation it becomes possible to interlace a grid-like multiple-layer warp with vertical and horizontal sets of wefts to produce a fully interlaced 3D fabric. This development therefore conclusively establishes that certain different types of fabric-forming processes, which are regarded as 3D-weaving, are technically not so because of the discrepancies in their assumed theory and actual practice. The supposed and the technically complying 3D-weaving processes are comprehensively explained here to make available their essential technical details and practical relevance as a complementary whole for the first time to form the necessary basis for initiating open discussions and to further their understanding and development.
