New thread is invisible to infrared cameras

Turkish thread manufacturer Durak Tekstil has developed its new Durak Poly-Strong PC-IR sewing thread to provide infrared (IR) invisibility. Developed as a solution to the infrared problems experienced by the military and security industry in the sewn areas of clothing and other materials, the new IR thread enables the camouflage feature to be used to its full potential.

Durak Tekstil Board of Directors vice president Yiğit Durak reports, “The infrared (IR) wavelength in the 700-1200 nm range of the electromagnetic spectrum is a spectral area that the human eye cannot see, but it can be detected by a few sensors. With new technological developments, invisibility against radar and IR sensors is the most important factor for security in the field in military and security applications. 

“Although camouflage clothing provides IR invisibility, this concealment could not be fully achieved due to both heat differences and surface connection gaps due to the stitching areas. With our new thread, camouflage becomes more perfect and complete invisibility is achieved. No IR camera in the 700-1200 nm wavelength range can detect our Poly-Strong PC-IR, it provides real invisibility,” he says.

The company says the dark military green tone of the thread is ideal for sewing military clothing and camouflage products. He noted that Durak Poly-Strong PC-IR sewing thread can also be used for outdoor sports clothing and materials such as tents.

The first studies on this thread started with a request from the Polish military administration, and an intensive R&D process started after the meetings. The thread has received approval from accredited laboratories and international independent institutes. The innovative thread can be used safely in products such as clothing, tents, bags and shoes where complete thermal invisibility is desired. 

The IR thread, which produces strong and durable seams, currently has a reflectance value in a safer range than the IR reflectance limit values ​​in the military field compared to similar products on the market.
