Anhui Haoyuan Chemical Group will cooperate with INVISTA and Kangtais to build a nylon 66 continuous polymerization production line with an annual output of 400,000 tons. The total planned investment of the project is 4.1 billion yuan. After completion and commissioning, the annual sales income will be more than 11 billion yuan.

Nylon 66 was developed by American chemist Wallace Carothers after many experiments to explore a fiber with similar appearance and gloss to natural silk, but also high strength and wear resistance – nylon 66. In 1938, Caro The research and development results of Arthur were officially granted a patent. In 1939, DuPont officially began producing nylon 66 at the world’s first nylon production plant in Delaware, USA. Because of its high temperature resistance, hydrolysis resistance, wear resistance, good flame retardancy, moderate density and other high comprehensive properties, it is widely used in the fields of engineering plastics, industrial fibers and civil fibers. Machinery, consumer goods and household appliances.

INVISTA is a global manufacturer of chemical intermediates, polymers and fibers. In 2004, Koch Industries acquired INVISTA (formerly DuPont Textiles and Interiors) from DuPont, providing nylon 66 series products, special Chemical intermediates and know-how licensing.
