The transformation and upgrading of printing and dyeing machinery drives the overall progress of the printing and dyeing industry

It is understood that the Ministry of Industry and Information Technology had previously held a national industrial system elimination of backward production capacity meeting, requiring that before the end of 2011, eliminate 74 type dyeing and finishing production lines, bath ratio than 1:10 intermittent dyeing equipment, elimination of backward models of printing Machines, hot-melt dyeing machines, eliminate outdated production process equipment with high energy consumption and high water consumption. As the country has formulated a more stringent energy-saving emission reduction target, the transformation and upgrading of the printing and dyeing industry is imperative, and the transformation and upgrading of printing and dyeing machinery is to take the lead.

The level of printing and dyeing machinery has obviously improved the development of the printing and dyeing industry in China in recent years. Both the printing and dyeing technology and the level of printing and dyeing equipment have been significantly improved, and more and more advanced domestic dyeing and finishing equipment has emerged, which is in line with the advanced level in the world. The gap is narrowing. The specific performance is: printing and dyeing production is changing the traditional extensive processing mode; the development and application of new printing and dyeing process technologies such as high-efficiency short flow and air flow dyeing; the equipment with low bath ratio and low energy consumption in the printing and dyeing industry is gradually increasing. The improvement of automation control level and precision of the equipment not only improves the quality of textiles, but also improves resource utilization and reduces the emission of pollutants.

In recent years, printing and dyeing equipment as a whole has developed toward the direction of environmental protection, energy conservation, emission reduction, time-saving and short-term processes. Judging from the current overall situation of the textile fabric market competition, the finishing process of printing and dyeing has increasingly become the key to determining the international competitiveness of fabrics. It has vigorously developed high value-added products adapted to the trend of international consumption, and applied advanced science and technology to develop new printing and dyeing machinery. , has triggered a new round of fierce fighting in the printing and dyeing machinery field.

At present, environmental protection and low carbon have become popular vocabularies nowadays and are now being promoted in various industries. With the demand for small batches and varieties of products, and the growing awareness of ecological issues, modern dyeing equipment is also more environmentally friendly and emphasizes low carbon. In recent years, printing and dyeing enterprises have actively carried out equipment transformation and technological innovation, adopting new equipment, new processes, and new technologies. Especially in the eastern coastal areas where printing and dyeing enterprises are relatively concentrated, the equipment with international advanced level has occupied a significant proportion.

Multi-intelligence is another major development trend of domestic printing and dyeing equipment. Regardless of performance or operation, printing and dyeing equipment is increasingly demanding humanity.

The printing and dyeing process determines the equipment flow, and the stability and automation of the domestic printing and dyeing equipment are still low. With the printing and dyeing process unchanged, the equipment flow can hardly be substantially shortened. According to this, some experts have suggested that the current practical approach in printing and dyeing machinery is to tap the potential of energy saving, water saving, and emission reduction in traditional production processes, and to equip waste water and waste heat recovery systems to reduce the amount of fresh water taken; Apply on-line inspection and control technology, standardize and optimize the printing and dyeing process, and reduce the amount and concentration of wastewater discharged.

As far as printing and dyeing equipment is concerned, Fujian has been quite eye-catching since last year, and this year the industry continues to maintain this good trend. According to reports, the increase in the demand for printing and dyeing equipment is due to the increasingly stringent national requirements for mandatory indicators for energy-saving emission reduction, which has led some companies to eliminate some non-energy-saving models, and to replace them with new ones. The equipment; on the other hand, due to the increase in the demand for velvet fabrics, velvet fabrics require higher and higher requirements for post-finishing, printing, and dyeing technologies, which directly drives the sales of equipment such as finishing and printing. Since the beginning of this year, the sales situation of enterprises producing large circular machines and computerized flat knitting machines in Fujian Province has also been very good.

Printing and dyeing technology upgrade At present, the application and development of printing and dyeing technology is also more and more advanced. It is understood that Shaoxing Dongsheng Digital Technology Co., Ltd. has independently developed a digital printing machine, which indicates that the company's non-watermarking and dyeing technology has been successfully developed, which brings hope for the gathering and upgrading of the printing and dyeing industry, energy conservation and emission reduction. The waterless printing machine is directly controlled by a computer. The dyes and auxiliaries are sprayed on the fabrics to get rid of the complicated processes such as plate making, pulping and printing of the traditional printing, thereby greatly shortening the production cycle.

Recently, the “Automatic Weighing System” of scientific and technological achievements independently developed by the printing and dyeing industry in Shishi City is being gradually promoted in the printing and dyeing industries both inside and outside the province. The automatic weighing system consists of a formula computer control and electronic scales and bar code scanners, which can effectively prevent human factors from falsifying the dyes and make the error range accurate to one hundred thousandth. The automatic memory function of the computer can prevent repeated weighing, and is associated with ERP management software, so that the weighing data directly enters the information management of the entire printing and dyeing process.

According to estimates, a printing and dyeing company with a monthly production scale of 3 million meters can directly use this system to reduce the dye cost by 75,000 yuan per month. It can also save about 20% of the auxiliaries. The economic benefits of energy saving and emission reduction for printing and dyeing enterprises are considerable. Because workers do not need to directly contact chemical dyes and auxiliaries, the harmfulness of the dyes to the employees' bodies is greatly eliminated, and the automatic weighing system fills the gaps in the intelligence and informationization of weighing processes in the printing and dyeing industry.

In addition, the automatic weighing system is also actively exported to the outside of the province. This is the first time Shishi printing and dyeing industry has exported high-tech printing and dyeing to and from the province.

The elimination of backward production capacity in the printing and dyeing industry was informed that the elimination of backward production capacity in the printing and dyeing industry was in full swing in various regions. High energy consumption, high water consumption, and high emission have become prominent problems that need to be solved in printing and dyeing production. Shaoxing County Environmental Protection Bureau proposed to closely focus on the development of ecological economy, optimizing the ecological environment, and prospering the ecological culture. It actively develops printing and dyeing industry clustering and upgrading projects, environmental comprehensive renovation projects, and ecological demonstration creation projects to comprehensively advance ecological civilization construction. It was learned from Chongqing Municipal Economic and Information Commission that the city will start a new round of elimination of backward production capacity, involving printing and dyeing and other industries.

Although China's printing and dyeing industry has made some progress in energy saving and emission reduction in recent years, most printing and dyeing enterprises still have insufficient investment in energy saving and emission reduction. The adoption rate of advanced technology and equipment is still low, and the energy saving and emission reduction targets in China's printing and dyeing industry remain the same. Long way to go.

In a word, the transformation and upgrading of printing and dyeing machinery and the entire printing and dyeing industry in China still have a lot of room for improvement. Printing and dyeing equipments require the development and application of energy-saving and emission-reducing dyeing and finishing equipment, energy and resource recovery and utilization technologies, such as high-efficiency, continuous and short-flow processes. Automatic production control. Eliminating outdated production capacity and achieving industrial transformation and upgrading are of great significance to the healthy development of the printing and dyeing industry. Eliminating outdated combination of technological innovation, while promoting the industry's scientific and technological progress, and promote enterprises to speed up industrial upgrading, and accelerate the realization of China's transition from printing and dyeing to printing and dyeing power.
