- Title
Future of rayon technical yarns.

- Abstract
The article highlights the possible increase in demand for rayon technical yarns due to the growth of the market for high performance (HP) and ultra high performance (UHP) automobile tires in 2004. Average tire size and speed index are increasing, while the average aspect ratios and acceptable tolerances for tires are decreasing. Carcass reinforcement materials have to meet these growing exigencies. Constraints for the carcass material of self supporting run flat tires are even harder. For these tires, thermostability is the main issue. The properties of rayon make it the material of choice for HP and UHP tires. For this reason, Cordenka expects a stable demand for the coming years. The rayon consumption for HP and UHP tires will grow, while for standard tires some substitution will go on. All rayon producers slightly increased their capacities or are intending to do so to safeguard availability of rayon. Cordenka has developed a new spinning technology for rayon but also holds the key patents for alternative cellulosic materials. Developments in the field of rayon/polyamide hybrid cords have been started. From an environmental point of view, a comparison between polyester, polyamide, and rayon shows no real advantages for either one of the three materials.
