Durak Tekstil, a leading manufacturer of industrial sewing and embroidery threads, continues to expand its technical product portfolio. The company has achieved successful results with its cut-resistant, conductive and insect repellent threads, and has developed the new Durak Poly-Strong PC-IR sewing thread, which provides infrared (IR) invisibility, especially for camouflage applications in military and security areas. Developed as a solution to the infrared problems experienced by the military and security industry in the sewing 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 said that camouflage is a technique that allows an object or person to become invisible by blending in with the environment it is in, expressing that more than traditional methods are needed due to developing new technologies. “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 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. The Poly-Strong PC-IR developed by Durak Tekstil stands out among the most innovative and ambitious products in this field. 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. In short, no IR camera in the 700-1200 nm wavelength range can detect our Poly-Strong PC-IR, it provides real invisibility,” he disclosed.

Durak stated that users gain a great advantage against IR sensors with special reflection values provided by special prescriptions in the production process, and emphasized that 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.
R&D studies for the new thread started upon the request of the Polish army
Yiğit Durak informed that the first studies on this thread started with a request from the Polish military administration, explaining that an intensive R&D process started for the IR thread after the meetings. He summarized the process of transition from idea to concept, from design to final product as follows; “The demand for IR invisibility has now become a necessity for the military and security industries due to developing technologies. With the R&D study we initiated, we determined the technical features of the thread as well as the special recipes for the production process and achieved successful results in a short time. Our Durak Poly-Strong PC-IR sewing thread, which provides invisibility in the specified IR range, has received approval from accredited laboratories and international independent institutes. We believe that this innovative special thread will be one of our strongest products in the international market”.
Durak Poly-Strong PC-IR sewing thread can be used in any application where invisibility is required
Durak Poly-Strong PC-IR sewing thread offers solutions to a lot of different areas, especially the military and security industry. This 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.

Durak Poly-Strong PC-IR sewing thread, which is offered in different thicknesses according to customer demand as well as its special khaki green color, provides textile manufacturers with new advantages for opening up to new markets and making applications. The thread shows superior resistance to movement and strain, and has internationally valid standards for washing, water, friction, hypochlorite, perspiration and light fastness. Durak Poly-Strong PC-IR also shows high resistance to mineral acids, alkalis, organic solutions and bleaching, meanwhile has the best melting, softening and shrinkage values for stable functionality. This innovative thread, which improves IR invisibility, contributes to the comfort and health of users by not allowing the formation of microorganisms such as fungi and mold as well.
“We believe that this new thread will take us to a different point,” said Yiğit Durak, emphasizing that they aim to expand the markets they address as a company. He concluded his words as follows; “We want to have more markets in military equipment production, as in the footwear and bed industry. Our wide product portfolio distinguishes us as a manufacturer that addresses different segments. Developing the production of our Durak Poly-Strong PC-IR sewing thread after the Polish army’s request and gaining this international experience makes us stronger. We also think that this product will be an important power for Turkish military equipment/clothing production. In addition, camouflage is not only used for military purposes, it is also used in many different areas such as nature sports, photography and so on. Therefore, Durak Tekstil, as an expert in technical threads, will have a strong share in the market in the coming period with Durak Poly-Strong PC-IR sewing thread.”
