Jute and Thermal Cameras
Updated: Feb 7
why to use it for multispectral camouflage
Jute and its properties have been the subject of discussion for several years. Despite being perceived by some as an outdated material unsuitable for modern warfare and criticized by others for its tendency to retain water, we believe that Jute still has a place in today's world.
This brief blog article will not delve into the outstanding visual and NIR camouflage effectiveness of Jute (only if properly processed), nor its low cost and relatively lightweight nature. The focus is hygroscopicity and how this can be wisely used to conceal against thermal cameras.
Indeed, Jute has high hygroscopicity, which is the ability of a material to absorb and retain moisture. This property has led to the exploration of its potential use in hiding from thermal cameras.
As you may already know, thermal cameras detect infrared radiation emitted by objects, which is then used to generate an image of the objects and their surroundings. In simple terms, thermal cameras pick up heat signatures, making it possible to detect people, animals, and objects that emit heat. In this regards, in terms of interfering with "reception of thermal radiation", the high hygroscopicity of jute can be used as an effective features for hiding from thermal cameras.
Jute, being a natural fiber, has a high moisture content that facilitates the absorption and retention of water molecules. As a result, Jute can quickly adapt to temperature changes and harmonize with the surrounding environment, much like natural vegetation. This helps to decrease the heat signature of objects and make them less visible to thermal cameras. The absorption of heat and moisture by Jute creates a cooler micro-environment around objects, further reducing their thermal signature.
The high hygroscopicity of jute can be effectively utilized by wrapping it around objects that need to be hidden from thermal cameras, or even better, by using Jute branches, Jute can be effectively used to build Ghillies with the aim of hiding from thermal cameras.
Jute fibers can also be used to create a jute-based fabric that can be used to create clothing or gear that can be worn to reduce the heat signature of the wearer. However, in order to achieve greater effectiveness, Jute should stay away from heat source or at least provide some air flow between the object/body and the Jute. This makes jute a suitable cost-effective material for military and tactical applications where hiding from thermal cameras is critical.
In conclusion, jute is a versatile and cost-effective material that can be effectively used to hide from thermal cameras due to its high hygroscopicity. The ability of jute to absorb and retain moisture makes it an effective material for reducing heat signatures hiding from thermal cameras. Whether used for tactical applications jute is a valuable material that is worth exploring for its multispectral hiding potential if properly treated. Lastly, Jute can be treated with flame-retardant products with ease, thereby enhancing its overall military requirements.
