Polyester is the world's largest and most widely used synthetic fiber variety, with polyester accounting for more than 60% of the world's synthetic fiber production. It is widely used in textiles such as clothing, bedding, various decorative fabrics, special fabrics for national defense and other industrial textiles, such as filter materials, insulating materials, tire cords, conveyor belts, etc. With the sustained and rapid growth of the domestic economy and the continuous improvement of the consumption power of domestic residents, the demand for polyester staple fiber in the domestic region is also growing. The production capacity of China's polyester series products is growing at an alarming rate. The rapid growth of polyester fiber production capacity has made China gradually develop into an important processing base for polyester products in the world.
As China's economy continues to grow rapidly and domestic consumption capacity continues to increase, the demand for domestic polyester fiber continues to grow. China's polyester fiber production capacity has grown at an alarming rate, making China gradually become an important processing base for the world's polyester products, and has become the world's largest producer of polyester fiber.
From 2001 to 2007, the market scale of China's polyester fiber industry showed an upward trend year by year. The market scale increased from 57.362 billion yuan in 2001 to 236.414 billion yuan in 2007, with a compound annual growth rate of more than 10%.
Polyester fiber is the most processed chemical fiber variety among all textile fibers. Developing differentiated varieties, increasing the added value of products, and improving the economic benefits of enterprises are of vital importance to the entire chemical fiber industry. Product differentiation is the development direction of polyester. China's polyester fiber producers are also developing in this direction. Therefore, the polyester industry still has great development potential.
