Textile Industry Leader Conquers Supercritical CO2 Water Free Printing And Dyeing Technology

Qingdao Jifa Group Co., Ltd. has achieved transformation and leapfrogging in 65 years from the rural handicraft industry file development cooperative in 1955 to the textile industry leading enterprise with an output value of more than 10 billion yuan this year. The innovative achievements of intelligent factory, waterless dyeing, intelligent clothing and other cutting-edge technologies have been born here one after another. Recently, "made in Qingdao" full media interview came to Qingdao Jifa Group Co., Ltd. to feel the innovative vitality of this new generation of "Qingdao Jinhua" cultivation enterprises.

Realize intelligent production, research and develop thousands of fabrics every year

Today's target, online production status of orders, summary of achievement rate of each group A number of electronic screens are set up in the ready to send finished products factory to present the data analysis of intelligent production line in real time.

According to the staff, this intelligent factory has realized the intelligent transformation and upgrading composed of intelligent production and intelligent management. An information system with ERP, MES, Internet of things and Internet of machines as the core is established. Combined with lean management, the real-time monitoring of all links of production and operation and the information interaction of equipment are realized, which greatly improves the management efficiency and the coordination level of supply chain, and promotes the transformation of enterprises from traditional mass and large-scale manufacturing to flexible production and agile manufacturing.

"Jifa develops thousands of fabrics every year, which is the core competitiveness of Jifa with an annual output of more than 200 million pieces." Yang Weidong, chairman of Qingdao Jifa Group Co., Ltd., said that in recent years, Jifa has abandoned the original low value-added products in the brand cultivation strategy and focused on developing high-tech and high-value-added products in the industry. Taking advantage of the strong technical advantages of the enterprise, we should constantly develop new products, promote the upgrading of brand products through technological innovation, technology introduction and technological transformation, and improve the grade and level of products.

Focus on independent innovation and conquer supercritical CO2 water free printing and dyeing technology

According to statistics, the annual discharge of textile wastewater in China is currently 2.5 billion tons (about 230 West Lake water), including 2 billion tons of printing and dyeing wastewater. Due to the dependence of traditional printing and dyeing on water resources and environmental problems caused by wastewater discharge, the sustainable development of the industry is restricted.

For this reason, Jifa has been committed to the research and development of supercritical CO2 water free dyeing industrialization technology for many years, and has overcome a number of key technical problems restricting the industrial production, and the product quality has met the requirements of relevant standards. "The application of non-liquid and non gas state of supercritical fluid not only can dissolve dyes, but also can quickly bring dyes into textiles. The whole process does not need a drop of water, and the dyeing time is significantly shortened." Wan Gang, deputy general manager of Jifa group, explained. It is understood that compared with the traditional water dyeing process, the technology does not need water and chemical additives, no wastewater discharge, CO2 can be recycled and reused, environmental protection and high efficiency.

As a leading enterprise in the knitting industry, Jifa always insists on taking independent innovation as the strategic basis for development, comprehensively deepens the construction of innovative brand, establishes the first technological center of enterprise in the same industry in China, invests a lot of money in scientific and technological innovation and technological transformation every year, and introduces a large number of scientific and technological research and development talents by using scientific research platforms such as academician workstation and postdoctoral workstation.

Enter the field of intelligent wear and upgrade the cross-border integration industry

As a leading enterprise in the domestic textile industry, in recent years, Jifa has turned its attention to the field of intelligent wear. "Compared with the traditional wearable device, this smart clothing should first ensure the accuracy of monitoring data, and then have the comfort of use." According to Wan Gang, in recent years, Jifa group has cooperated closely with top scientific research institutes and team organizations in the domestic industry to jointly develop Yiyi Lianke wearable smart clothes. As a kind of clothes that understand the human body better, Yiyi Lianke wearable smart clothing focuses on health management and safety management, which can effectively collect dynamic information of the body, monitor the health status of users in real time, realize remote warning and reduce health risks.

Chitosan fiber protective mask, marine biological chitin fiber clothing In the exhibition hall of the technology center, many cutting-edge products are displayed. It is reported that around the concept of cultivating new material industry and modern marine industry, Fafa has established a number of high-end scientific research platforms such as green technology product research laboratory and chitin Material Engineering Research Center. On the basis of obtaining the registration certificate issued by the State Food and drug administration, the company has continuously accelerated the pace of industrialization, expanded the production and sales of new hemodialysis materials, and accelerated the march from traditional textiles to industrial textiles and life science textiles.

"How to use science and technology to lead innovation driven and create an upgraded version of China's textile industry is a problem that Jifa has been thinking about." Yang Weidong introduced that the next step will continue to make efforts to cross-border integration. Through the continuous emergence of new technologies, new products and new achievements, it will drive the rapid formation of new industries, new formats and new models, and create a Chinese "weaving" brand with a sense of science and technology and a sense of fashion.
