The customer was troubled by the enormous costs and manpower associated with snow removal, such as "snow brought in near the tunnel" and "snow removal from road signs on the main line," as well as the social issues that inadvertently arise. Therefore, in a space within the Yuzawa Interchange in Yuzawa Town, Niigata Prefecture, known for heavy snowfall, we laid down a snow-melting mat about the size of 2 to 3 tatami mats and conducted snow melting tests. We monitored the area with a network camera, and throughout one season, we achieved excellent snow melting effects, which has led to great confidence in our solution. 【Overview】 <Customer's Concerns> ■ Snow countermeasures on highways ■ Enormous costs and manpower associated with snow removal, as well as social issues that inadvertently arise <Solution> ■ Conducted snow falling experiments on signposts and snow melting verification on interlocking pavements and paved roads ■ Achieved excellent snow melting effects throughout one season *For more details, please refer to the PDF document or feel free to contact us.

Our company processes fibers with dyes and chemicals that are difficult to treat as waste liquids, and processing is possible if the materials can be dispersed in water. Fibers that carry (are dyed with) ferrocyanide compounds such as iron, copper, and nickel efficiently remove and recover cesium ions. Colored fibers can be freely deformed and cut, and can be easily bent. Additionally, fibers that have adsorbed radioactive cesium can be collected as needed and stored in managed containers or incinerated in incinerators equipped with dust treatment functions (for volume reduction). 【Features】 ■ Good water permeability, simple, and effective decontamination medium ■ Can be placed in various locations ■ Selectively concentrates (captures) radioactive cesium in fiber form ■ Can be handled in the same way as ordinary fibers *For more details, please refer to the PDF document or feel free to contact us.

Our company can coat inorganic materials (powder) onto fibers, which cannot be achieved through conventional dyeing, and if the material can be dispersed in water, it can be coated onto the fibers. Each individual thread is fully coated with "carbon nanotubes," forming a network that exhibits excellent contact conductivity. Additionally, because we use polyester multifilament processed yarn as the base material, it excels in bending fatigue compared to carbon fiber wires and metal wires, achieving a soft texture. 【Features】 ■ Compatible with various levels of electrical resistance ■ Stable electrical resistance values ■ Fully conductive ■ High durability, bending fatigue resistance, and soft texture ■ Lightweight and compact *For more details, please refer to the PDF document or feel free to contact us.

CNT coating conductive fibers can produce threads with electrical resistance values ranging from 10^3 to 10^10 Ω/cm. Each level of thread has a stable electrical resistance value in the length direction. The surface of each single fiber is fully coated with carbon nanotubes, forming a network that exhibits good contact conductivity. Even during stretching deformation, the change in electrical resistance value is minimal, demonstrating high durability. Since the base material is polyester multifilament processed yarn, it excels in bending fatigue compared to carbon fiber wires and metal wires, achieving a soft texture. It also realizes significant weight reduction and compactness compared to metal wires. For more details, please contact us or refer to the catalog.

"The CNT coating conductive fiber surface heating fabric" is a thin, lightweight, and soft heating material that excels in bending fatigue resistance. The front side of the fabric generates heat without any hot spots. It is a woven fabric that incorporates conductive fibers coated with carbon nanotubes in the weft and polyester threads along with copper fine wires in the warp. The copper fine wires in the warp act as electrodes, connecting to the CNT-coated fibers in the weft to allow current flow and generate heat. Since all the weft threads of the fabric generate heat, the entire fabric heats evenly. It is compatible with power supplies ranging from 5V to 200V, allowing for designs that meet the target heating watt performance (W/m2). There is virtually no wire breakage due to bending fatigue.
