Huafon Chongqing Spandex Co., Ltd.: The World's Largest Single-Site Intelligent Spandex Manufacturing Base
Huafon Chongqing Spandex Co., Ltd. was established in August 2013 as a wholly owned subsidiary of Huafon Chemical Co., Ltd. The company is located in Huafon Industrial Park, Baitao Chemical Park, Fuling District, Chongqing, China. Benefiting from the energy resources of Southwest China and the transportation advantages of the Yangtze River, the facility has become one of the two core spandex manufacturing bases of Huafon Chemical, working together with the Ruian production base in Zhejiang to form an integrated east-west manufacturing network.
The company has planned a differentiated spandex project with an annual production capacity of 460,000 tons, developed in multiple phases across an industrial site covering approximately 813 mu (about 54 hectares). Construction of the first phase began in 2014 and was successfully commissioned, while subsequent capacity expansions have been implemented according to market demand. Today, the facility has grown into the world's largest single-site spandex manufacturing plant.
The factory primarily produces the "Qianxi" (Millennium) brand of spandex filament while continuously expanding its portfolio of specialty products. Its offerings include chlorine-resistant spandex, heat-resistant spandex, high-resilience spandex, hygiene-grade spandex, black spandex, and low-temperature bonding spandex. These products are suitable for circular knitting, warp knitting, covered yarn, narrow fabric weaving, and other textile manufacturing processes. They are widely used in sportswear, underwear, swimwear, stretch denim, socks, medical elastic bandages, hygiene materials, and other elastic textile applications. Products are exported to more than 40 countries and regions worldwide.
Digital transformation and intelligent manufacturing have become central to the company's long-term development strategy. Huafon Chongqing Spandex continues to upgrade its production lines through automation while implementing advanced technologies such as AI-assisted process control, machine vision inspection, digital twin systems, and integrated manufacturing data platforms. These technologies connect production, quality control, warehousing, and order management into a unified digital workflow.
In early 2026, the company was included in the World Economic Forum's Global Lighthouse Network, becoming the first enterprise in the global chemical fiber industry to receive recognition as a Lighthouse Factory for manufacturing productivity. This achievement represents a significant milestone in the transformation of traditional spandex manufacturing toward intelligent production. Ongoing digitalization has improved production efficiency, reduced defect rates, and increased labor productivity.
In the area of sustainable manufacturing, the company continues to optimize energy efficiency and solvent recovery technologies used in spandex production. It has developed an integrated multi-column solvent recovery system that improves both recovery efficiency and solvent purity while introducing cascade utilization of low-temperature waste heat generated during spinning processes. These initiatives help reduce the overall energy consumption per unit of production. The company has established a comprehensive environmental management system, implements clean production standards, and consistently maintains emission performance exceeding national regulatory requirements. It has also obtained internationally recognized quality and environmental management certifications.
Continuous innovation supports the development of advanced products and manufacturing technologies. Huafon Chongqing Spandex has established its own research and development platform and collaborates with universities and research institutions on projects involving polymerization technology, spinning equipment, functional material formulations, and energy-saving manufacturing processes. A number of proprietary technologies have reached advanced industry standards. Through sustained R&D investment, the company continues increasing the proportion of high-value-added specialty spandex products to meet growing demand from premium textiles, healthcare materials, and hygiene applications.
From a management perspective, the company has adopted an excellence performance management system while establishing a customer-oriented technical service platform. By integrating its marketing and R&D teams, it provides customized processing and application solutions for downstream customers. The company has received several regional honors, including Chongqing Manufacturing Single Champion Enterprise and the Chongqing Mayor Quality Management Award, reinforcing its position as a leading advanced materials manufacturer in Southwest China.
Facing cyclical changes in the textile industry and increasing global competition, Huafon Chongqing Spandex continues to strengthen both its production scale and product portfolio while accelerating low-carbon and intelligent manufacturing initiatives. Leveraging the integrated upstream and downstream industrial chain within Huafon Industrial Park, the company remains committed to advancing differentiated polyurethane elastic fibers and further enhancing the global competitiveness of China's spandex industry.
