Warp Knitting Camou Nets

Adaptive camouflage is also currently under development because today’s camouflage nets appear to be too two-dimensional due to their unnatural regularity. In addition, large camouflage nets reflect the cold from outer space, so that they might be detectable as cold spots. Thus artificial vegetation that is actively cooled and heated is to imitate the heating up and cooling off of tufts of grass, for example, and be selectively positioned on the camouflage nets. It is also conceivable, but not yet under development, that the tufts of grass independently adapt to the respective temperatures.

Thermal Targets are also pursued based on the same technology. Thermal Targets are textiles with integrated heating which, for example, imitate the heat signature of tanks.

 

Ultra-thin, electrically conductive warped knitted netting makes it possible to produce extremely light and foldable large reflectors for satellites. Tec-Knit manufactures warp knitted netting from ultra-thin, gilded molybdenum yarns for the radar reconnaissance satellite TechSAR for the Israeli military. They are opened up like an umbrella in outer space. Above all, the structure of the knitted fabrics is crucial for the reflector properties. The reflector must also exhibit a certain degree of electrical conductivity in its deployed state. In order to precisely adjust these properties the client is on location at the start of production. A total of 20 centimeters are warp knitted, tested on site, the machine adjusted and then another 20 centimeters are warp knitted. This process usually takes several days in order to then produce 50 meters per year – a quantity that is unusually small for the textile industry. However, Tec-Knit is the only manufacturer of folding reflectors of this kind in Europe. The satellites are suitable for military deployment, but can also be used for civilian purposes – for example, for determining the ripeness of fruit.
