Energy Saving Way Of A Yarn Of Weiqiao Group

"Emerging industries continue to grow, traditional industrial production methods are also constantly upgrading, and the 'green content' makes the 'gold content' of economic development continue to increase..." On July 20, the CCTV Zhaowen World column reported the green and intelligent development of the textile industry of Shandong Weiqiao Venture Group Co., Ltd. under the title of "Energy Saving Road of One Yarn".

　　 "A combed cotton yarn used for clothing, from cotton planting and ginning, to intermediate processing into roving and spinning, to finished product transportation and warehousing, the carbon footprint value of 1kg cotton yarn is only 4.393kg CO2 equivalent. This carbon footprint assessment report issued by the China Textile Industry Federation shows that Shandong Weiqiao Venture Group Co., Ltd.'s textile production is green The level of industrialization is the best in the industry. " Previously, the People's Daily published on April 12 reported that "the green level of textile production of Shandong Weiqiao Pioneer Group Co., Ltd. has been among the best in the industry" under the title of "Intelligent transformation and precise control of textile workshops to achieve energy conservation and consumption reduction".

In recent years, based on the fact that the traditional manufacturing industry in which Weiqiao Venture Group is engaged is large in scale and difficult to transform, Weiqiao Venture Group has actively focused on upgrading and transforming existing assets. The implementation path is mainly aimed at the development direction of "high-end, intelligent and green" to promote high-quality development of enterprises. Among them, the Weiqiao textile sector has successively transformed and built 11 intelligent branches, promoting the digital upgrading of enterprises with the "intelligent matrix", saving more than 50% of labor, more than 40% of energy consumption, more than 20% of water consumption, and the overall technology has reached the international leading level. It has won the first prize of China's textile industry scientific and technological progress, the national intelligent manufacturing demonstration factory More than ten honors, such as national level green factory, have played an exemplary and leading role in the intelligent development of the industry.

Journalists from CCTV and People's Daily have successively walked into the spinning workshop of Weiqiao Textile Green Intelligent Third Factory, where 62 giant spinning machines are running at full speed. On each machine, more than 1800 snow-white spindles are lined up like keys, from which yarns as thin as hair are pulled out. Occasionally, there will be a red light flashing on the machine to remind the workers on duty to continue to connect the yarn. When Zhang Jing, a staff member, was interviewed by CCTV reporters, she introduced: "Now, we have a sensor on each spinning spindle, which can transmit all the problems on the spindle to an intelligent platform, and the lathe workers can arrive at the site within one minute after the problem occurs. In the past, if the line is broken in the production process, workers need to check one by one according to the route. During this period, the equipment can only be idle, which costs labor and electricity. Through technical transformation, 90% of energy waste can be reduced by spindle wiring alone. "

According to CCTV, "Weiqiao textile can save energy without rejecting the slightest hint. There are many green management applications like this. For example, workshops can save 15% of electrical power consumption by accurately controlling temperature and humidity in different zones according to production requirements. 150000 sensors are used for quality inspection to replace traditional manual sampling, saving tens of thousands of meters of sampled yarn per shift."

The People's Daily also focused on the "green technology" and "green products" of Weiqiao Textile.

Weiqiao Textile actively promotes green production process. In an interview with the People's Daily, Cheng Wangjian, the chief of the Third Green and Intelligent Weiqiao Textile Factory, said: "Sizing is a necessary link before spinning, and the strength of yarn can be increased only after being coated. However, the size often contains PVA (polyvinyl alcohol) powder, which cannot be degraded in nature." Sizing process has been optimized by adjusting the size proportion and reforming high-pressure sizing equipment, Not only does PVA not need to be added, but also 50% steam and 30% slurry can be reduced.

"According to the traditional process, bacteriostatic agents must be added in the dyeing and finishing of the antibacterial fabrics we produce, which also requires a lot of water and electricity to deal with the residual sewage." Ren Changyou, general manager of Weiqiaote Wide Printing and Dyeing Company, said that through strengthening the cooperation between industry, university and research, advanced micro nano inlaid spinning technology was used to produce antibacterial fabrics. At present, there is no need to add bacteriostatic agents, and the whole process is pollution-free More water saving.

In terms of green product research and development, Weiqiao Pioneer Group has made great efforts to break through the bottleneck that domestic Lyocell fiber cannot be used for high count pure spinning. The raw material of Lyocell is derived from renewable forest wood pulp, which saves more water than cotton. The textiles developed by Lyocell can be naturally degraded, and it is a green product with excellent performance. Lv Zhijia, director of Weiqiao Textile Technology R&D Center, said: "In brief, the higher the count, the thinner the yarn, and the lighter, softer and more breathable the fabric. Since 2017, we have tackled more than a dozen key technologies, such as spinning, weaving, and dyeing, one by one, and Lyssell's pure spinning and high count spinning technology has been granted the national invention patent." Driven by the R&D project, The sales of Lyocell fabrics of the company increased significantly.

Zhang Hongxia, Secretary of the Party Committee and General Manager of Weiqiao Venture Group, said in an interview with the People's Daily: "Adhere to green development, so that while creating good ecological benefits, we have also opened up new fields, new tracks, and new driving forces and new advantages." This year, Weiqiao Textile will strengthen green and low-carbon management in an all-round way, and build two new green and intelligent chemical plants, Expand the proportion of green fiber products, deepen green and low-carbon cooperation with the upstream and downstream of the industrial chain, and accelerate to become the industry benchmark of green textiles.
