T700 carbon fiber yarn JT49S is made by dry-jet wet spinning technology. As a benchmark product for domestic substitution in China, it matches the mechanical properties of international mainstream T700 carbon fiber (such as Toray T700SC) while offering higher cost-effectiveness and stable supply capacity. Currently, JT49S series products (including 12K, 24K specifications) have been exported to EU countries such as Germany, Italy and France, and widely used in automotive, wind power, pressure vessels and other downstream fields worldwide. With independent intellectual property rights and ten-thousand-ton-level production capacity, it provides reliable and cost-effective high-performance carbon fiber solutions for global customers.
