With the deepening of reform and opening up, the development of China’s chemical fiber industry is very rapid.Since 1998, China’s chemical fiber output ranked first in the world for the first time, and China’s chemical fiber output has ranked first in the world for 11 consecutive years.Among them, China’s annual chemical fiber output in 2009 was about 26 million to 26.8 million tons, an increase of 8-11% year-on-year.
Chang yizhi, a research fellow in the chemical industry at China investment consulting, pointed out that in recent years, China’s chemical fiber industry has not only been growing in output, but also made some achievements in the development of technology and products.
In terms of technological development, China’s chemical fiber industry in the early years is basically a complete set of imported foreign production technology and equipment, to the 1990s, the rapid development of the world’s chemical fiber industry technology and equipment in China has been widely used.In recent years, China’s chemical fiber industry has been continuously improving its domestic technology and equipment level and engineering design capacity by absorbing international advanced technology and independent innovation.By 2006, the main technology and equipment of the chemical fiber industry had basically reached the international advanced level in the late 1990s, and some of them had reached the international advanced level in the early 21st century.
For example, major breakthroughs have been made in the domestication of polyester complete sets of equipment and projects. Polyester filament projects and technologies have been developed and widely used, while the domestication of complete sets of technical equipment such as viscose, spandex and nylon cord fabric have also been successfully developed and popularized.Chang yizhi believed that the progress of these technologies not only effectively narrowed the gap between China’s chemical fiber industry and the world’s advanced level, but also improved the overall competitiveness of China’s chemical fiber industry in the world.
In terms of product development, China’s chemical fiber industry has become an industrial system with a complete variety and a reasonable structure.According to cic advisory issued by “2010-2015, China chemical fiber industry investment analysis and prospect forecast report, according to the types of chemical fiber products mainly include polyester, polyamide, acrylic, polypropylene fiber, spandex, whalen, viscose, etc., including chemical fiber filament length ratio is about 3:2, polyester production accounts for about 80%, acrylic, nylon accounted for 4.6% and 4.7%, respectively.
Chang yizhi also pointed out that in order to meet the needs of the development of China’s textile industry, while developing traditional chemical fiber products, new chemical fiber varieties have been put into production in China, and the research and development of differentiated fiber has gradually begun to pay attention to.
For example, among the new chemical fiber varieties put into production, the annual output of nonferrous fiber, network silk, fine denier silk and high-strength low-elongation sewing thread has exceeded 10,000 tons.The annual output of high shrinkage fiber, special-shaped fiber, polyester cationic dye-modified fiber also exceeds 1000 tons.Meanwhile, new fibers such as carbon fiber, poly (propylene terephthalate) (PTT) fiber, arind 1313 and high-performance superfine fiber developed independently in China have also played an important role in aerospace and military industry.
In addition, the product differentiation rate has also been improved.According to the investment analysis and prospect forecast report of China’s chemical fiber industry from 2010 to 2015 released by cic consultant, the differentiation rate of China’s chemical fiber products was 22% in 2000, up to 31% in 2005, up to 38% in 2007, and up to 2009, the differentiation rate of chemical fiber products reached about 43%.
