China's first "one-step spinning" new process

A new type of spinning technology, direct spinning of polymer melt (abbreviated as "one-step spinning"), has been successfully developed by researchers in China and passed the expert appraisal organized by the China Textile Industry Association. Experts believe that the results of the development of continuous polymer melt direct spinning polylactic acid filament new technology, new technology and the development of polylactic acid filament and its downstream products, fill the gaps in the domestic, will give chemical fiber, textile,
Clothing and other industries have brought about major changes.
Polylactic acid fiber is a new type of polymer fiber material obtained from corn starch as raw material by bacterial fermentation and chemical synthesis methods. Because it has both the physical characteristics of chemical fiber and the green environmental characteristics of natural biodegradable fiber, it also has a broad and deep downstream industrial chain. Since its inception in the early 21st century, it has rapidly become a focus of attention in the international textile and apparel industry. one.

Chang Jing Institute of Applied Chemistry, Chinese Academy of Sciences, and his research team cooperated with Changshu Changjiang Chemical Fiber Co., Ltd. and organized the "Study of continuous polymer melt direct spinning polylactic acid fiber technology and technology" for the first time since 2006. The polylactic acid filaments are spun on a model device. On this basis, they independently developed a continuous polymerization direct spinning device with a capacity of 59 tons per year and a “film reactor” as the core. Recently, they successfully spun polylactic acid filaments on the device. Tested and dyed by the fiber inspection institute of Jiangsu Province, the main technical specifications of the polylactic acid filaments reached the level of the US sliced ​​spinning polylactic acid fibers.

Experts believe that at the current time when fiber-grade polylactic acid pellets and their production technology cannot be imported from abroad, this achievement has pioneered the “one-step spinning” new process, which not only fills the gaps in the country but also is currently used by the United States and Japan. Comparing with the "sliced ​​spinning" process, the process flow is shortened, the melt decompression is reduced, the production cost is reduced, the fiber quality is guaranteed, and China's competitiveness in the international polylactic acid market is enhanced.
