The New Textile Industry Needs To Upgrade The Level Of Informatization.

Recently, the reporter interviewed the chairman of Changzhou Hongda Technology Group.

Reporter: what are the advantages of printing and dyeing enterprises applying intelligent information control system?

Gu Ren: after nearly more than 10 years of rapid development, China's printing and dyeing industry is facing unprecedented challenges of environmental protection, energy costs and labor costs.

"Printing and dyeing industry access conditions" clearly pointed out that printing and dyeing enterprises should adopt sustainable production technology, improve the efficiency of resource utilization, and control the amount of pollutants from the source of production.

It also stipulates that advanced technology should be adopted in the process and equipment of printing and dyeing enterprises, and the equipment with low pollution intensity, energy saving and environmental protection should be adopted. The main equipment parameters should be on-line detection and automatic control.

In the past two years, most printing and dyeing enterprises have noticed and strengthened environmental protection and energy saving, such as the installation of heat recovery and light alkali recycling equipment, but the production process is far from finer and data oriented. The production process is still relatively extensive, and the success rate is relatively low. "Over drying", "over washing" and waste of energy are still very serious. Many processes are still realized by manual assurance, and the labor intensity of many production process workers is very strong.

The application of intelligent information management and control system can solve the difficulties faced by printing and dyeing enterprises and ensure the sustainable development of enterprises in the future.

Reporter: please give a detailed introduction to the intelligent information management and control system developed by Changzhou Hongda.

Gu Ren: the intelligent information management and control system of Changzhou's grand printing and dyeing production process is divided into three levels.

Through the successful application of MAX-300 alkali concentration online detection and control system, MSC-U fabric moisture content on-line detection and control system, MSC-X humidity humidity on-line detection and control system, PH-500 type pH value on-line detection and control system, HD-M gate amplitude online detection and control system, HD-M gate amplitude on-line detection and control system, HK-500 pre shrinkage detection and control system, Changzhou Hongda realized automatic detection and control of key parameters of pretreatment process, dyeing and finishing process, and automatic detection and control of pre shrinking rate is the first level.

The system uses PLC, frequency converter, servo driver and man-machine interface communication technology, so that the shrinkage of the pre shrinking finishing machine is stable, and the shrinkage rate and intelligent control shrinkage can be detected online.

Through the key technologies such as pre shrinkage detection, compaction detection and control, moisture detection and control, tension detection technology and system filtering technology, the integrated equipment of the pre shrinkage stabilization system, the pre shrinkage detection system and the pre shrinkage control system is finally integrated to achieve the intelligent management of the single station.

The second level is to increase the application and promotion of automatic control and digital management of single station.

The automatic control and digital management of single stand is to quantify the control of the technological parameters of single machine platform, overcome the errors caused by human factors, and realize the process reproduction through memory and storage process menu, thus greatly improving the success rate of printing and dyeing.

For this reason, the company has focused on the digital solution of printing and dyeing equipment. For example, in the numerical control printing and dyeing system for pre dyeing and printing process, we can further divide auxiliaries automatic feeding system, intelligent uniform liquid on-line detection and control system, horizontal washing tank, steaming box, automatic temperature control system of drying cylinder, automatic adjustment system of hydrogen peroxide concentration detection, automatic adjustment system for light alkali concentration detection, detection of residual moisture content, water, electricity, gas, auxiliaries, automatic measurement, storage, data pmission system and so on.

It is the third level to realize intelligent information management and control in printing and dyeing production process.

At present, the process parameters of printing and dyeing enterprises in production process have not yet been automated and networked. Only by manual recording, the process digitalization management can not be realized.

The intelligent information management and control system of printing and dyeing production directly operates the single to machine terminal functions of the process, satisfies the management personnel's requirements for recording various field process parameters, greatly improves the success rate, realizes the overall monitoring and control of printing and dyeing process, and improves the processing adaptability, thus greatly reducing the production management cost and greatly improving the profit margin.

The system also includes printing and dyeing energy management system, which can help printing and dyeing enterprises to carry out four levels of management, clearly understand the energy usage of each link, calculate the carbon emissions of each link, estimate the carbon consumption of each stage of the product life cycle, and make the energy utilization of the enterprises clear at the same time through automatic collection, automatic calculation, automatic analysis, automatic management, automatic optimization and automatic diagnosis, and even enable managers to understand the ranking of the energy utilization rate in the industry and how much room for improvement, so as to optimize the production status of the enterprise from the source.

The energy management system, while benefiting printing and dyeing enterprises, can also provide energy saving and emission reduction data and energy consumption for the government, and is conducive to promoting the implementation of laws, regulations, policies and standards in the areas of low carbon emissions and green economy.

Reporter: intelligent information management and control system has been applied in many printing and dyeing enterprises. What's the actual effect?

Gu Ren: Changzhou Hongda printing and dyeing digital series products have been registered in the national software products and have been successfully applied in the printing and dyeing enterprises in Zhejiang, Shandong, Fujian, Guangdong, Jiangsu and other key textile provinces, which have been well received by the customers.

After printing and dyeing enterprises use Changzhou Hongda printing and dyeing digital series products, they can not only save caustic soda and steam, but also save water, electricity and so on.

The alkali concentration on-line detection system is applied to the mercerizing machine as an example. It can recycle 4 tons of caustic soda 80g/L per day and save 550 thousand yuan a year.

It is estimated that after printing and dyeing a series of digital products, steam can save 6.1%, coal consumption 10%, water consumption 25%, and electricity saving 15%.

Great social and economic benefits have been achieved in water saving and energy saving.

Reporter: what do you think the future development of intelligent information control system is? What is the direction of future development?

Gu Ren: at present, the intelligence and informatization level of the equipment and production process of the domestic dyeing and printing enterprises is relatively low, far from meeting the requirements of the state for energy conservation and emission reduction, and the industry needs to be upgraded urgently.

If every printing and dyeing enterprise invests 2 million yuan in intelligence and information upgrading, it will be calculated by 2000 enterprises above Designated Size, then the domestic market demand will reach 4 billion yuan, which has broad market prospects.

In the future, Changzhou will further increase investment in R & D, overcome technical difficulties and improve product system.

In order to meet the digitalization of the whole process of the textile industry chain, Changzhou Hongda Technology Group has set up a machine vision Department relying on Tsinghua University and Chinese Academy of Sciences. Its machine vision products include automatic cloth inspection, automatic product grading and other systems. Batik printing has been successfully applied to flower control system in Qingdao Phoenix, Jining Ruyi printing and Shandong home textiles.

Through user data comparison and cost accounting, it is proved that the system can effectively improve the grade of products and superior quality of wax dyeing cloth, reduce the risk of doing single business in batik dyed enterprises, save considerable raw materials, reduce consumption and reduce the number of employed workers, thereby reducing production management and improving profit margins.

The whole system has strong anti-interference ability and reliable operation.

The editor in detail introduced the online acquisition system tailored by Hangzhou Kaiyuan Computer Technology Co., Ltd. for domestic printing and dyeing enterprises. The online monitoring and control system for printing and dyeing pretreatment parameters developed by Xi'an de Gao printing and dyeing Automation Engineering Co., Ltd. and the intelligent information management and control system launched by Changzhou Hongda Technology Group were finished.

It is hoped that this group of reports will enhance the understanding of printing and dyeing enterprises to domestic online testing technology and products, and promote this technology with good energy-saving and emission reduction effects to be applied more widely.
