Influence of 3D Warp Interlock Fabric Parameters on Final Geometry

FRANCOIS BOUSSU, CAROLINE CHEVALIER, CHRISTOPHE KERISIT and DANIEL COUTELLIER

Abstract


The exact geometry of 3D warp interlock fabric during production is highly dependent on the weaving process. Several fabric parameters as the number of layers, the weave diagram of linking warp yarns and the end and pick densities can influence the final geometry. Several fabrics have been produced on the same dobby weaving machine using para-aramid yarns with different warp and weft densities. Thanks to these observations, differences between final geometries of 3D warp interlock fabric as the different position of yarn insertion and the cross-section shapes have been revealed.
