Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns (“wales”) of knitting, rather than a single row (“course
The camouflage netting covers radar as both as near and far-infrared frequency ranges. A special coating also imitates the so-called chlorophyll curve, i.e. when the netting is evaluated it exhibits the same frequency ranges that are characteristic of chlorophyll in leaves.
Adaptive camouflage is also currently under development because today’s camouflage nets appear to be too two-dimensional due to their unnatural regularity.
Camouflaging by imitating “heat signatures”.

Warp knitting and biotextiles
The warp knitting process is also being used to create biotextiles. For example, a warp knitted polyester cardiac support device has been created to attempt to limit the growth of diseased hearts by being installed tightly around the diseased heart. Current research on animals “have confirmed that…the implantation of the device reverses the disease state, which makes this an alternative innovative therapy for patients who have side effects from traditional drug regimes”.
