Tire cords are an integral part of a tire and account for over 30% of its production costs. Their quality has a direct effect on the tire performance. With the demand for green materials rising among global tire manufacturers, OTIZ has also been focusing on developing green materials. Its innovation, nylon 56, is made of fermented bio-materials. As a replacement for nylon 66 for the tire cord fabric, OTIZ is alleviating the world from its reliance on fossil fuels. As a replacement for nylon 66, nylon 56 further reduces the world’s reliance on fossil fuels. Nylon 56 has higher moisture regain, environmental sensitivity and thickening rate compared with nylon 66, making it difficult to stabilize the spinning process. Without any prior examples as guidance, OTIZ collaborated with R&D Center for the material testing. By applying its technological knowhow and calibrating production parameters, OTIZ was able to identify the most ideal manufacturing conditions to deliver nylon 56 with consistent quality that exceeds customer demands. The production process costs less and emits 30% less GHG emissions than that of nylon 66, making nylon 56 an environmentally sustainable material.
