Since polyester staple fiber entered large-scale industrialization in the 1970s, its development speed is far higher than that of other synthetic fibers regardless of its technical level or production variety. The main target market for polyester staple fiber is to replace and partially replace natural fibers, especially cotton fibers.

The main market applications for civilian polyester staple fiber are pure or blended woven and knitted garments, civilian sewing threads and home textiles. Compared with the field of industrial textiles, civilian textiles, as the most basic living resource, occupy an extremely important strategic position in the development of the national economy.

The development of civilian polyester staple fiber production technology can be broadly divided into three major stages: from the mid-1980s to the mid-1990s, the industrialization of large-capacity melt conveying technology was successful, which promoted the industrialization of short-fiber large-capacity direct spinning production lines. The process has been greatly shortened, product quality (especially uniformity) has been further improved, and production costs have been greatly reduced. In 1997, the capacity of civilian direct spinning staple fibers accounted for more than 80% of the total production capacity. From the mid-1990s to mid-century, direct spinning included melting. The development of new products, including body modification, has become the focus of technological progress. The output of new products accounts for about 50% of the total, which not only brings considerable economic benefits to fiber producers, but also lays the foundation for the development of the textile market; 2005 So far, the energy consumption of the production process has been further reduced, and the efficiency of downstream processing has been improved. Green environmental protection and sustainable development have become the focus of technological development and product development.
