Multi-Axial Warp Knit Fabrics

A Multi-axial warp knit fabric essentially consists of four yarn layers placed in perfect order each on top of the other. Each layer shows the uniformity of the non-crimped parallel yarns interlaced by stitches. The structure is dimensionally stable in all directions: +45°/-45°/0°/90°. Multi-axial multi-ply structures are fabrics bonded by a loop system, consisting of one or several yarn layers stretched in parallel. Said yarn layers may have different orientation and different yarn densities of single ends. Multi-axial multi-ply fabrics are used to reinforce different matrices. The combination of multi-directional fibre layers and matrices has proved capable of absorbing and distributing extraordinarily high strain forces. The typical feature of warp-knitted multi-axial multi-ply structures for substrates is the interlacing of single ends in line with the stitch courses and the associated almost smooth processing of fed yarns. These products are multi-ply structures with angles of 30° up to 60° and/or 90°/0°.

Applications: inflatable bodies, such as airships, inflatable boats, inflatable life-rafts, rescue tents, gas membranes, V-belts, flexible roofing membranes etc.
