It is a high energy consumption, high pollution and labor intensive industry.

Data show that China's textile sewage accounts for third of the total national sewage discharge, and the largest emission comes from textile printing and dyeing.

In recent years, the labor cost of our country is increasing at an average annual rate of 10%. In the process of printing and dyeing of textile products, there are still many production links that need a lot of labor.

Through the intellectualization of equipment, we should deal with the loss of population dividends and promote green environmental protection in the production process.

Single machine is more intelligent.

Recently, Jiangsu SEG Textile Machinery Co., Ltd. held a new product promotion conference.

At the meeting, the company launched a new intelligent environmental protection high speed desizing and boiling bleaching machine.

According to the introduction, the equipment has been absorbed and absorbed by Jiangsu SEG company's advanced design concepts in Europe, and will be exported to the Turkey market after the pformation and innovation.

Bao Dequan, general manager of SEG, told reporters that this model represents the highest level of printing and dyeing machinery and equipment in the world, and its key components are in line with international standards.

The equipment has outstanding performance in high speed, high efficiency, energy saving and environmental protection.

Bao Dequan said that the current domestic single station

Intelligent development is very good. Intelligent equipment, apart from the well-known substitution of labor and labor saving, has another important advantage in controlling production costs and production management.

In terms of cost, automatic feeding is realized through intelligent equipment, and the consumption of water, electricity and steam is precisely controlled to reduce unnecessary waste.

In terms of management, intelligent system realizes online monitoring and remote diagnosis through ERP, Internet, LAN, etc., and is more conducive to order management and process storage. Especially in the process of re production of customers, the equipment already stored is effective to avoid the chromatic aberration between printing and dyeing effect.

Hangzhou open source computer technology Co., Ltd. has also developed a number of intelligent products.

According to Xu Changyuan, manager of Hangzhou open source marketing department, the intelligent products of the company have three main parts, namely, multi type net making machine, automatic computerized mixing system and MES printing and dyeing online collection system.

Among them, the company's open source Blu ray net machine uses a precise focusing and stable UV laser system to directly expose the pattern on the printing screen with precoated photosensitive glue to get the screen needed for printing. It overcomes the dependence on medium in the traditional network making process, and realizes low cost, high speed and high precision direct networking.

The open source Blu ray machine can complement each other with open source and other netting products to meet the needs of differentiated production of high and low end customers, and create the best network efficiency for customers.

The automatic computer mixing and mixing system applies color space theory, case-based reasoning, color light viscosity mathematical model, database, full closed loop control and precision weighing technology to printing and sizing, dyeing and mixing. It can accurately control key processing parameters of pulp, achieve rapid automatic sizing and liquid distribution and residual slurry reuse, and achieve energy saving and emission reduction.

Changzhou Hongda Technology Group has done a good job in the research and development of intelligent online monitoring system for dyeing and printing equipment.

Gu Ren, chairman of the group, said that Changzhou's grand online monitoring system mainly includes three main categories: printing and dyeing environmental protection digitization system, energy saving and emission reduction digitization system, and printing and dyeing production intelligent information management and control system.

The printing and dyeing environmental protection digitization system has the digital monitoring platform for sewage treatment, the on-line detection of flue gas emission, etc. the digital system of energy saving and emission reduction has intelligent steam energy saving system and WT series accurate water consumption on-line measurement and control system. The intelligent information management and control system of printing and dyeing production includes HVMC-15 series intelligent weickning and finishing machine, wax dyeing and rotary screen printing machine vision automatic flower control system, HV-TT20 intelligent fabric density meter, HD-100 hydrogen peroxide concentration on-line detection and control system and PH-500 pH. pH online detection and control system.

The successful development of these systems has basically realized the whole process monitoring of printing and dyeing production process.

Effectiveness of continuous improvement

Speaking of the current situation of intelligent printing and dyeing equipment in China, Li Yi, vice president of China Textile Machinery Association, believes that the intellectualization of dyeing and printing equipment is mainly manifested in two aspects: information flow and logistics.

At present, various online monitoring systems developed by domestic spinning and weaving enterprises have been relatively mature, and they have realized the collection and processing of all kinds of information in the production process. In terms of logistics, the R & D products of enterprises have basically realized the intellectualization of single machines, and truly realize the whole process intellectualization and continuity among different production processes. At present, only the "digital automatic dyeing technology and equipment of cheese yarn" developed by Shandong Kangping Nash group.

At the national science and Technology Awards Conference held recently, the Shandong Kangping Na group's "cheese yarn digital automatic dyeing technology and equipment" won the first prize in science and technology progress.

This achievement has overcome 10 key technologies, such as automatic weighing, humidity control and dyeing, which are of great significance for promoting the pformation and upgrading of the textile industry.

According to the introduction, this system realizes the pformation from manual mechanization to single automation to automation system, and achieves the innovation of the three systems, especially in reducing labor, improving product quality, saving energy and reducing emissions.

According to Liu Lin, general manager of Kangping Shandong group, cheese dyeing is a key step to produce high-grade fabrics, enhance product functions and add value.

In view of the difficulties in the sustainable development of the textile and dyeing industry, such as labor intensive, 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, which are suitable for the automatic digital dyeing process of the cheese, the central automatic control system for the whole process of digital automatic dyeing equipment and dyeing production, and the establishment of the digital automatic and efficient dyeing line of the yarn, and the establishment of the digital dyeing workshop, making China the first country in the world to break through the whole process automation dyeing technology and realize the engineering application.

This set of equipment can be made of cotton yarn.

Various kinds of cheese dyeing, such as cotton and linen yarn, can also be extended to dyeing, printing and other fields. It can save 27% tons of yarn, save 19.4% of steam, save electricity by 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, pformation and upgrading to intensive, large-scale production, and low consumption, low emission green color industry.

With the rapid development of electrical automation technology, the complicated mechanical structure of printing and dyeing machinery and equipment has been gradually replaced by electrical control system. The mechanical structure has been greatly simplified, the failure rate has been effectively reduced, and the control accuracy has been improved, thus achieving a leap in the quality of printing and dyeing machinery.

Li Yi believes that the achievements of the domestic printing and dyeing intelligent equipment such as single machine and on-line monitoring should be known as "numerical control". In the way of Kangping's "cheese automatic digital dyeing technology and equipment", the realization of mechanization from manual mechanization, automatic integration to whole process digitalization and automation of system automation is the real sense of intelligence, and is also the direction for the development of intelligent equipment in the future.

Bao Dequan also shared the same view.

He believed that, combined with the development of printing and dyeing industry, the future development trend of printing and dyeing machinery and equipment should not only simplify the whole machine structure, promote high speed and high efficiency, realize the on-line monitoring and remote diagnosis technology of key process parameters, closely follow the development trend of personalized and functional textiles, develop and adapt to the dyeing and printing equipment of small batch, multiple varieties, and one machine with many functions, more meaningful direction is to develop process equipment suitable for continuous dyeing and finishing of knitted fabrics, enhance the dyeing and finishing efficiency of knitted fabrics, and achieve continuous and intelligent whole process.
