"Super imitation cotton" series fiber products have the properties of cotton moisture absorption, softness and warmth, and also have good mechanical properties, heat resistance and color fastness of polyester.
In 2012, China's chemical fiber output was 37.92 million tons, of which polyester production was 30.57 million tons, accounting for 80% of the total chemical fiber, accounting for more than 70% of the world's total polyester. Therefore, it is especially necessary to further improve the technical water products in the polyester industry and carry out further development of a new generation of polyester (imitation cotton) fibers with versatility, high quality, low energy consumption and low emissions. This is also a way to adapt to the development trend of the industry and consolidate and expand the application market.
In 2011, the Chemical Fiber Industry Technology Innovation Strategic Alliance undertook the national “Twelfth Five-Year†Science and Technology Support Program “Technology Development of Super-Imitated Cotton Synthetic Fiber and Its Textile Industryâ€. Twenty-seven enterprises in the upstream and downstream of the polyester industry chain have jointly tackled the problem. After more than two years of hard work, the project undertakers have successively launched “super-imitation cotton†fibers to the market. The reporter interviewed Pan Jufang, director of the Deep Processing Research Office of the Research and Development Center of the China Textile Science Research Institute, on the progress and prospects of the project.
Internal communication process
Reporter: In August 2011, the National Science and Technology Support Technology Project organized by the Chemical Fiber Industry Technology Innovation Strategic Alliance - "Ultra-imitation Cotton Synthetic Fiber and Its Textile Industrialization Technology Development" was launched, China Textile Science Research Institute (hereinafter referred to as "Drying Branch" The hospital is also one of the project undertakers. How do the projects undertaken by the Academy of Textile Science carry out?
Pan Jufang: Before the development of the project of “Ultra-imitation cotton synthetic fiber and its textile industrialization technology developmentâ€, the Textile Research Institute has accumulated 3 to 4 years of research and development experience of new generation polyester fiber (imitation cotton). At that time, the original intention of R&D was to make differentiated products for China's huge polyester production capacity and improve the competitiveness of the polyester industry.
The Textile Institute has undertaken some of the projects in the “Super Imitation Cotton†project, and has accelerated the development of a new generation of polyester fiber (imitation cotton). In this project, he mainly played the roles of organizer and technology development. The role of the organizer is reflected in the involvement of upstream and downstream related companies to participate in the project, jointly develop research and development plans, and promote the project process. The role of technology development is reflected in the formation of a development team in the form of a project team. Within the Institute of Textile Science, the various processes in the industrial chain were first opened, and then targeted in the cooperation with enterprises.
Reporter: Does this mean that the Textile Institute must master the technology in the entire industrial chain?
Pan Jufang: We started a series of technical developments such as polymerization, spinning, weaving, dyeing and finishing from the polymerization modification of polyester. Often a company cannot complete all process research and needs to carry out different production processes in different companies. After we get through the process inside, it is much more convenient to try on the machine of the company. The Institute of Textiles also has machines for production in some processes, which can be trial-produced in its own units.
The development of fiber, starting from a small amount, from a few tons to tens of tons to hundreds of tons, step by step to expand production capacity, after the product is mature and stable, it is widely promoted in the industry. The hydrophilic anti-UV staple fiber jointly developed by the Institute of Textile Science and Yizheng Chemical Fiber Co., Ltd. and Jiangyin Huahong Chemical Fiber Co., Ltd. was born.
Registered trademark sharing, standard certification
Reporter: The project research and development has achieved some results, and registered the "Yi Mian" trademark. Can you talk about the attribution of trademarks?
Pan Jufang: The research and development of the project, if it is developed by a single unit, belongs to the R&D unit; if it is jointly developed by multiple units within the alliance, the results are jointly owned by the alliance members. “Yi Mian†is a common trademark of the entire project. In the internal enterprises of the alliance, products that meet the positioning and standards of “super-imitation cotton†products can use the “Yi Mian†trademark. At present, the Academy of Textiles is setting standards in this area. In the early stage, a large amount of experimental data has been collected. Standard setting is also a huge project.
In the future, the alliance will promote the promotion of “Yi Mian†fiber products, promote the market scale application of “Yi Mian†fiber and its textiles, create a reliable market brand, and enhance the added value of products. At the same time, it will also strengthen the work of standard setting, quality supervision and certification, and comfort evaluation to ensure the scientific standardization and branding of new product marketing.
More advanced polymerization modification, in line with the trend of the future
Reporter: What is the difference between the previous "imitation cotton" products and the current "super-imitation cotton" products?
Pan Jufang: If you trace the roots, the ordinary polyester itself will be available from the perspective of “imitation cottonâ€. It is the first generation of imitation cotton products. But it has some inherent insufficiency in performance compared to cotton. For example, the moisture regain rate is much lower than that of cotton, and the water wicking performance is worse than cotton.
After that, most of the modified polyesters developed by many companies were physically modified, but only changed the cross-sectional shape of the polyester, and the polyester properties themselves did not change. To say that the "super-imitation cotton" project is different from before, it should be said that more advanced technology is the main aspect. The essential difference from physical modification is that the molecular structure design of the polyester is carried out in this project, which is a polymerization modification, which is a breakthrough in the performance of the fiber itself.
"Super imitation cotton" series fiber products combine the excellent characteristics of cotton and polyester to improve their respective shortcomings. They have the properties of cotton moisture absorption, softness and warmth, and also have good mechanical properties, heat resistance and color fastness of polyester. It can also achieve functions such as perspiration, quick-drying, antistatic, anti-pilling, etc. or flame retardant, antibacterial and anti-ultraviolet.
Reporter: How do you view the market prospects of the "Super Imitation Cotton" series of products?
Pan Jufang: During the promotion process, we pay great attention to the low carbon environmental protection of the production process. This is consistent with the industry's development trend, so the product has a competitive advantage in green technology. In addition, the "super-imitation cotton" products have outstanding performance, which is in line with the current trend of consumers pursuing a healthy and comfortable life, and also has advantages in the market competition. At present, the “Super Imitation Cotton†project is progressing smoothly, and a new generation of polyester (imitation cotton) product system map has been established. We will continue to strengthen the follow-up research and development work of the products and provide technical support for upgrading the product quality.
