The "Super Imitation Cotton" series of fiber products combine the best qualities of cotton and polyester. These fibers offer excellent moisture absorption, softness, and warmth—characteristics typically associated with natural cotton—while also delivering the strong mechanical properties, heat resistance, and color fastness of polyester. Additionally, they can be engineered to provide advanced functionalities such as quick-drying, anti-static, anti-pilling, flame retardancy, antibacterial properties, and UV protection.
In 2012, China's chemical fiber output reached 37.92 million tons, with polyester accounting for 30.57 million tons, representing 80% of the total chemical fiber production. This made up more than 70% of the world’s polyester output. Given this massive scale, it became essential to enhance the technical capabilities of the polyester industry and develop a new generation of polyester fibers that are versatile, high-quality, energy-efficient, and environmentally friendly. This innovation not only aligns with industry trends but also helps expand the application market for these materials.
In 2011, the Chemical Fiber Industry Technology Innovation Strategic Alliance launched the national "Twelfth Five-Year" Science and Technology Support Program titled “Technology Development of Super-Imitated Cotton Synthetic Fiber and Its Textile Industrialization.†Twenty-seven companies across the polyester supply chain collaborated on this project. After more than two years of dedicated research, the project successfully introduced "super-imitation cotton" fibers to the market. The reporter spoke with Pan Jufang, director of the Deep Processing Research Office at the China Textile Science Research Institute, about the progress and future prospects of the initiative.
Pan Jufang explained that prior to this project, the Textile Research Institute had already spent three to four years developing next-generation polyester fibers with imitation cotton characteristics. The goal was to create differentiated products to address China’s large-scale polyester production capacity and improve the industry’s competitiveness. As one of the project participants, the institute played a key role in organizing collaboration between upstream and downstream enterprises, helping to shape development strategies and accelerate the project’s progress.
The institute also led the technological development, forming cross-functional teams to work on different stages of the production process. By opening up internal processes and working closely with partner companies, the team ensured efficient development and testing. Some of the institute’s own facilities allowed for small-scale trial production, which helped speed up the commercialization process.
One of the notable outcomes of the project is the hydrophilic anti-UV staple fiber developed jointly with Yizheng Chemical Fiber Co., Ltd. and Jiangyin Huahong Chemical Fiber Co., Ltd. This product has become a key example of the success of the "Super Imitation Cotton" initiative.
The project also involved the registration of the "Yi Mian" trademark, which is shared among all participating enterprises. Products that meet the project's standards can use this brand, promoting consistency and trust in the market. The institute is currently working on setting industry standards, collecting extensive experimental data, and building a solid foundation for future certification and quality control.
Looking ahead, the alliance aims to promote the widespread adoption of "Yi Mian" fiber products, enhancing their market presence and creating a strong brand identity. The focus will be on standardization, quality assurance, and consumer comfort evaluation to ensure that the new products are both scientifically sound and commercially viable.
Compared to earlier "imitation cotton" products, the current "super-imitation cotton" represents a significant technological leap. While traditional polyester was modified through physical means—such as altering the fiber's cross-section—the new approach involves polymerization modification, which changes the molecular structure of the polyester itself. This results in improved performance, making the fibers more similar to natural cotton in terms of comfort and functionality.
With its eco-friendly production process and superior performance, the "Super Imitation Cotton" series is well-positioned to meet the growing demand for sustainable and high-performance textiles. As consumers increasingly seek healthier and more comfortable living options, these fibers are set to play a key role in shaping the future of the textile industry. The project continues to advance, with a clear roadmap for further innovation and product improvement.
