Analysis Of Digital Automatic Dyeing Technology And Equipment For Cheese Yarn

The technology and equipment of digital automatic dyeing of cheese are major breakthroughs in the digitalization and intellectualization of China's textile and dyeing industry. Cheese dyeing is a key step to produce high-grade fabrics, enhance product functions and add value in the textile and dyeing industry. In view of the difficulties in the sustainable development of the textile and dyeing industry, such as low production efficiency, poor dyeing quality, high energy consumption and large amount of wastewater discharge, the equipment has developed three major innovations, namely, dyeing process, equipment and system, to develop the automatic control system for the automatic dyeing of the yarn, digital automatic dyeing equipment and the whole process of dyeing production. A digital automatic and efficient dyeing line has been created, and a digital dyeing workshop has been set up. It has realized the crossing from manual mechanization, single machine automation to whole process digitalization and system automation, making China the first country in the world to break through the whole process automation dyeing technology and realize its engineering application.

The technology of digital automatic dyeing of cheese yarn has greatly improved the quality and efficiency of textile dyeing and the level of energy conservation and emission reduction. The equipment has realized more than 100 sets of equipment, more than 2000 parameters on-line detection and real-time whole process closed loop control, all realized automation, saved more than 70% jobs, surpassed the advanced international technology level such as Germany and Italy. Through the dyeing of this equipment, the chromatic aberration increased from the original grade 4 to the above 4.5 grade. The passing rate of dyeing once reached over 95%, 5 percentage points higher than that of the international advanced level, and the process stability and production reliability increased from 57% to 95%, effectively realizing the efficiency and quality improvement of dyeing production. This equipment can be used for dyeing all kinds of cheese yarn such as cotton yarn, wool yarn, cotton yarn and so on. It can also be extended to dyeing, printing and other fields. It can save 27% tons of yarn, save steam 19.4%, save electricity 12.5%, and reduce sewage discharge by 26.7%. China's dyed yarn is 10 million tons per year. After the equipment is popularized, it can save 3 tons of water every year, save 2 million 330 thousand tons of standard coal, and reduce the discharge of sewage by 2.97 billion tons. It helps to promote the printing and dyeing industry to achieve high-quality and efficient dyeing, spanformation and upgrading to intensive, large-scale production, and low consumption, low emission green color industry.

The technology and equipment of digital automatic dyeing of cheese are fully independent intellectual property, and the effect of industrialization and marketization is remarkable. The equipment has 32 patents granted by the state (including 14 invention patents) and 13 software copyrights. Its full-automatic dyeing production line and its technical products are already in Lu Tai. Spin More than 30 enterprises such as Fu Ye group, YOUNGOR group, Daxin textile and so on have been applied and dyed to produce more than 80 thousand products, such as cotton, wool, silk, hemp and chemical fiber. The products are exported to more than 30 countries and regions such as the United States and Italy. The effect of water saving and emission reduction is remarkable, which brings obvious economic and social benefits.

　　 Cheese yarn Digital automatic dyeing technology and equipment has created a successful mode of deep cooperation between textile, dyeing and printing industry, and is a pilot project for textile printing and dyeing industry to accelerate the construction of the 4 industry. Shandong Kangping Na Group Co., Ltd. and Machinery Science Research Institute and Shandong Lu Tai Limited by Share Ltd, through continuous in-depth production and research cooperation, adhere to the "technological innovation driven equipment technology innovation, equipment innovation and engineering package". technology The innovative concept of "research and development pays equal attention" has accelerated the intensity and speed of innovation. It has initiated the research and application demonstration of the technology and equipment of digital automatic dyeing of cheese based on central control, and has truly achieved the organic integration of product technology and equipment technology, textile technology and intelligent equipment, and promoted the industrialization of technology and equipment. The technology and equipment of digital automatic dyeing of cheese yarn have provided important technical support for improving the high quality manufacturing and green production of textiles. It has made useful explorations for promoting the digital factory, intelligent manufacturing and networking services in China's textile industry, and promoted the "two integration" integration, spanformation and upgrading of textile industry, and boosted the spanformation of textile power to textile power.
