Interpretation of the Outline: dyeing and finishing - providing strong support for gorgeous textiles

dyeing and finishing is an important link in textile production. Whether the dyeing and finishing technology is advanced or not directly affects the use value of textiles. The outline of scientific and technological progress in the textile industry during the 12th Five Year Plan period (hereinafter referred to as the outline) points out that one of the key tasks of scientific and technological progress in the textile industry during the 12th Five Year Plan period is to strengthen the R & D and promotion of efficient short process pretreatment technology for printing and dyeing, printing and dyeing technology without water and less water, and functional finishing technology. Among the 50 key technologies in ten categories proposed in the outline, 6 (including 22 sub items) involve high-tech printing and dyeing, and 20 of the 110 advanced applicable technologies promoted throughout the industry involve dyeing and finishing

during the 11th Five Year Plan period, the progress of dyeing and finishing technology has greatly improved the quality and functional level of textile fabrics, and a large number of new printing and dyeing technologies have been continuously promoted. What projects will the dyeing and finishing industry focus on during the 12th Five Year Plan period? Which projects will be promoted? Recently, Li Jinbao, director of the science and Technology Development Department of China Textile Industry Association and President of China printing and dyeing industry association, was interviewed on the achievements of China's textile dyeing and finishing technology during the 11th Five Year Plan period and the key points of dyeing and finishing technology R & D and promotion during the 12th Five Year Plan period

22 R & D objectives are targeted.

the "12th Five Year Plan" textile industry science and technology research and industrialization project proposed in the outline involves 6 high-tech printing and dyeing technologies, including high-efficiency short process pretreatment technology, low water and anhydrous printing and dyeing processing technology, printing and dyeing detection and digital technology, textile functional finishing technology, hemp fiber dyeing and finishing technology and special additives, new fiber and multi-component fiber fabric dyeing and finishing key technologies

lijinbao introduced that the industrialization project of high-efficiency short process pretreatment technology is mainly to break through the biological enzyme scouring technology, the key technology of cotton fabric low-temperature bleaching, tea saponin scouring and bleaching and other high-efficiency short process technologies, as well as the cold pad batch pretreatment processing technology of knitted fabrics. Lijinbao introduced that the research on these technologies is progressing smoothly. Shortly after the release of the outline, the biological enzyme pretreatment technology jointly developed by Donghua University, Liaoning Hongfeng printing and dyeing Co., Ltd. and other units has been successfully completed and the industrialization pilot has been carried out. Next, the key promotion will be carried out; Recently, the key technology of low-temperature bleaching of cotton fabrics jointly researched and developed by Donghua University, Huafang Co., Ltd. and Qingdao kangdi'en Biotechnology Co., Ltd. has also made major breakthroughs. At present, it is undergoing pilot test in Huafang Co., Ltd

the outline proposes to focus on the development of high-tech printing and dyeing processing with less water and no water, so as to provide technical support for the industry to achieve cleaner production and improve its sustainable development ability. Lijinbao introduced that the wet short steaming dyeing of reactive dyes mainly adopts special steamers, which are strictly and accurately controlled by computers to adapt the temperature to the dyeing and fixation speed of dyes, so as to realize salt free and short process dyeing of reactive dyes. The wet short steaming technology under development in China has the advantages of short process, high fixation rate, full dye penetration, uniform and bright color, energy and chemicals saving, and less waste water discharge. Compared with the conventional rolling steaming process, it can comprehensively save 30%~50% energy. There are three key technologies to be solved in the future. One is the development of transfer printing combined with digital inkjet paper; The second is to expand the chromatography of natural fiber transfer printing to improve the color fastness; The third is to explore the technology and equipment of transfer printing and paperless printing. It is reported that chemical fiber transfer printing has been successfully industrialized

the outline points out that it is necessary to focus on the research of printing and dyeing detection and digital technologies such as the network monitoring system for the whole process of printing and dyeing production, and the efficient digital printing integration technology, so as to improve production efficiency and promote energy conservation and emission reduction. Lijinbao introduced that the network monitoring system for the whole process of printing and dyeing production should further solve the key technologies of the digital acquisition system for the printing and dyeing production process in the future. The research and development of high-efficiency digital printing integrated technology should focus on three aspects: first, strengthen the development of ink-jet printing machine nozzle; The second is to strengthen the development of high-efficiency and low-cost inkjet ink; Third, strengthen the development of high-speed inkjet printing machine. Up to now, China has successfully developed computer color separation, inkjet plate making and textile inkjet printing systems, which are used for printing proofing in printing and dyeing enterprises. If it is used in industrial production, it is necessary to further develop nozzles, improve speed and develop low-cost inks

the textile functional finishing technology proposed in the outline mainly includes composite function, finishing and processing technology and protection technology under extreme conditions. Lijinbao said that the key problem to be further solved by the former technology in the future is to realize the combination of heat storage and temperature regulation, waterproof and moisture permeable, sweat absorption and quick drying, skin care, anion, antibacterial, anti UV, anti radiation, far-infrared finishing functions and effectiveness, safety and fashion. Especially plastic deformation, indentation or scratch Before pressing the specified indenter into the surface layer of metal materials, multifunctional finishing additives and finishing processes are being developed in China to study the synchronization of finishing processes and the coordination of finishing effects, so as to endow fabrics with multiple functions. At present, good achievements have been made in the development of far-infrared, anti electromagnetic wave, water and oil repellent, UV resistant and antibacterial textiles. The key problem to be solved by the latter technology in the future is to research and develop functional finishing technologies for textiles under extreme conditions such as high temperature difference, high light and heat radiation, fire and high-energy rays

hemp fabric has poor softness, difficult dyeing and poor color fastness. It is urgent to develop corresponding dyeing and finishing technologies to improve the wearability. The key dyeing and finishing technologies of new fiber and multi-component fiber fabrics mainly include new fiber dyeing and finishing technology, differentiated and functional high value-added fiber dyeing and finishing technology, and short process dyeing and finishing technology of multi-component fiber fabrics
