At the 2015 National Science and Technology Award Conference held on January 8, 2016, two textile projects recommended by China National Textile and Apparel Council won the second prize of the National Science and Technology Progress Award.

One of the projects is the “Development and Industrialization of Key Technologies for PTT and In-situ Functional PET Polymerization and Composite Fiber Production”. It is jointly undertaken by Shenghong Group Co., Ltd., Beijing Institute of Clothing Technology and Jiangsu Zhonglu Science and Technology Development Co., Ltd. The project has developed slow-release crystallization and granulation technology that can save energy up to 27-35% as well as the cyclic dimer depolymerization, separation and recycling technology that can reduce material consumption and realize harmless disposal of acrolein and allyl alcohol. Based on investigating the moisture management, anti-static, UV-proof and anti-pilling principles of multi-functional copolyester fibers and the kinetics of synthetic reaction, the project has successfully developed complete solutions for thermal-wet comfort polyester fiber from polyester synthesis to fiber production; solved the problem of hyper dispersion of functional powder; developed the key technologies for multi-functional polyester continuous polymerization and melt-spinning; and produced thermal-wet comfort polyester filament and staple with different function combinations and related fabric.

The other prize-winning project is the “Development and Industrialization of Key Technologies for High-precision Rotary-screen Printing and Clean Production”, which is jointly undertaken by Yuyue Home-textiles Co., Ltd., Tianjin Polytechnic University, Qingdao University, Tianjin Dek Chemical Co., Ltd., Shandong Tongda Nickel Screen Co., Ltd., Fujian Jinjiang Jilong Machinery Co., Ltd. and Shandong Huanghe Delta Institute of Textile Science and Technology. The project has developed innovative extra-wide high-precision screen-making technology and rotary-screen printing technology, solved the problems such as poor pattern accuracy, low one-time success rate, long time cycle of color separation and tracing, low productivity, poor color gradation and brightness, color paste waste, high screen-making cost and high discharge of wastewater which are often seen in traditional rotary-screen printing process, and realized clean industrial high-precision printing of extra-wide fabric.
