New IR-Reflecting Viscose Specialty Fiber

Kelheim Fibers, a leading manufacture of viscose specialty fibers, developed the next step of new IR-reflecting fibers. According to the several spinning trials, the new viscose specialty fiber integrating mineral IR-reflecting particles delivers a level of IR-activity. This could be proven in measurement of the Total Solar Reflectance Value. The results of measurement showed that visible light is reflected by 90 to 95%, while in the near infrared range, a reflectance of up to 90% is reached, depending on the wavelength spectrum. In the mid-IR-range, this new IR-reflecting viscose specialty fiber can reflect about 20% more of mid-IR radiation compared with that of normal viscose. This new IR viscose fiber can provide a cooling effect by reflecting the direct sunlight and protecting the human body from outside radiation. At the same time, it may also provide a warming effect by keeping the human body warm, where the thermal radiation emitted from the body is reflected by these mineral IR-reflecting particles back to body. The level of loading these particles can be adapted according to the requirements of the final product providing high versatility. For the next step, the new viscose specialty fiber will be tested for its effectiveness in various end-applications in cooperation with Kelheim Fibres’s partners. (Source: www.kelheim-fibres.com)


New Aramid Fiber Fabrics for Protection form Airborne Volcanic Fragments by Teijin

 

Twaron


Teijin is the world’s only company manufacturing two types of lightweight, strong and heat-resistant para-aramid fibers that are Twaron and Technora. Twaron offers six times more tensile strength than steel of the same weight, and superior heat resistance and elastic modulus. Technora is much greater tensile strength and resistance to impact, fatigue and chemicals. Teijin announced that it has developed two new aramid fiber fabrics made of Twaron and Technora para-aramid fibers to protect evacuation facilities and other structures from large airborne volcanic fragments measured as much as about 10 cm. Although the other materials such as reinforced concrete and steel also offer required levels of strength and durability, the transportation of heavy materials and large equipment to highland cause the problems in higher construction costs and longer construction period. In addition, the deteriorating effect of severe weather on steel is also another problem. Teijin will focus marketing on new aramid fiber fabrics on local municipalities and private enterprises in areas prone to volcanic activity, with sales expected to reach 50,000 square meters by the fiscal year ending in March 2017.

OctaTM Neo Multilayer Fiber by Teijin Frontier

Teijin Frontier Co., Ltd., the Teijin Group’s fiber-product converting company announced their development in OctaTM Neo which is a sheath-core fiber using Octa filament as its core material. Octa has a unique cross section comprising eight fins aligned in radial pattern around a tube-like fiber. OctaTM Neo combines the low weight, high bulkiness, water adsorption, water diffusion, stiffness and breathability of Octa with the texture and softness of staple fibers selected, such as cotton, rayon, acrylic, wool or Teijin Frontier’s heat converting fiber, for diverse applications. Teijin Frontier plans to release OctaTM Neo in time for 2017 spring/summer sportswear and underwear applications. OctaTM Neo is also an ideal fiber for uniforms, bedding and various materials. Annual sales are targeted to reach 500,000 meters by the fiscal year ending in March 2020. (Source: www.intertextileapparel.com)
