< p > in 2013, China Textile Industry Federation science and Technology Award and Hongkong sang Ma textile science and Technology Award project successively issued, the theme of fiber innovation and application throughout, covering cotton, linen, wool, silk, chemical fiber and many other < a href= "http://www.91se91.com/news/ index_s.asp" > fiber field < /a >.

Many of the winning projects have broken the blockade of foreign technology.

For example, the key technology of "5000 tons per year PAN based carbon fiber precursor" has played an exemplary and promoting role in promoting the sustainable development of China's carbon fiber industry, technological innovation and upgrading of the textile industry.

< /p >

< p > resource recovery and utilization, turning waste into treasure is the key to sustainable development of the industry.

Many enterprises have already seen this potential.

For example, the waste of sericin in the production process is distressing, and the key technology and industrialization of sericin recovery and comprehensive utilization have focused on solving the problem of sericin recovery and reuse. In the main application enterprises, the newly increased production value is 144 million yuan and the foreign exchange earning is 1 million 700 thousand yuan.
