From the overall situation of textile market competition, printing and dyeing finishing is becoming the key to decide the international competitiveness of fabrics. Vigorously developing the high value-added products that adapt to the international consumption trend, and applying advanced science and technology to develop new printing and dyeing machinery have caused a new round of fierce fighting in the field of printing and dyeing machinery.

From the domestic point of view, most of the printing and dyeing equipment manufacturers in the last century focused on the production of continuous equipment. In the 90s of last century, the development of intermittent and semi continuous printing and dyeing equipment was only concerned, and the equipment with low bath ratio and low energy consumption came out one after another.

However, it has been estimated that the output of cotton and polyester cotton dyed and dyed fabrics processed by continuous processing accounts for 80% of the total output of printed and dyed fabrics.

Therefore, the domestic low-grade equipment has become a "soft rib" in the domestic printing and dyeing industry.

According to the latest statistics of China Textile machinery and equipment industry association, in 2010 1~2, the textile machinery industry achieved sales revenue of 10 billion 644 million yuan, an increase of 54.19% over the same period, an increase of 65.27 percentage points compared with the same period last year. The total assets amounted to 63 billion 370 million yuan, an increase of 18.15% over the same period last year, and the growth rate increased by 15.61 percentage points over the same period last year.

Among them, dyeing and printing machinery occupies a large proportion.

These data can reflect that China's printing and dyeing machinery industry has been innovating by importing and assimilating advanced foreign manufacturing technology, and the performance of the new printing and dyeing equipment has been continuously improved, and it is breaking through the "soft rib" of the domestic low-grade printing and dyeing equipment.

Bathing environmental protection low carbon breeze

Environmental protection, low carbon, now

industry

They are all advocating and become popular words nowadays.

With the market demand of small batch and multi varieties and the growing awareness of ecology, modern dyeing equipment has begun to bathe under the fresh breeze of environmental protection and low carbon, so that the state and small enterprises have paid more attention to environmental protection and emphasized low carbon.

The state has issued a number of policies, with repeated orders and efforts, and the pformation of busy equipment and elimination of backward production capacity.

High energy consumption, high water consumption and high emission have become prominent problems in printing and dyeing production.

In the textile industry adjustment and revitalization plan, the printing and dyeing industry is clearly required to solve the problems of high energy consumption and high water consumption and serious environmental pollution. The energy consumption of the added value of enterprises should be reduced by more than 10%, and the reuse rate of the intermediate water should be over 35%. The printing and dyeing equipment requires strengthening the development and application of energy saving and emission reduction dyeing and finishing equipment, energy and resource recycling technologies, and improving the level of automatic production control.

In recent years, printing and dyeing enterprises have been actively carrying out equipment pformation and technological innovation, adopting new equipment, new technology and new technology, especially in the eastern coastal areas where printing and dyeing enterprises are relatively concentrated.

In this respect, the added value of printing and dyeing products has been enhanced. On the other hand, it has saved resources and reduced pollution. It has played an important role in promoting the sustainable development of the industry.

In 2000~2008, the proportion of printing and dyeing wastewater reached the total discharge volume increased from 77.91% to 94.81%, increased by 16.9 percentage points in 8 years, and the effluent volume of 10000 yuan output value decreased from 182.32 tons / 10000 yuan to 86.98 tons / 10000 yuan, and 52.29% in 8 years.

The amount of wastewater discharged from industrial added value in 2000~2007 was reduced from 885.55 tons / 10000 yuan to 389.12 tons / million yuan, a decrease of 56.06%.

Li Jinbao, President of the China printing and dyeing industry association, said in an interview with this reporter that eliminating backward production capacity and realizing industrial pformation and upgrading is of great significance to the healthy development of the printing and dyeing industry. Eliminating backward and combining with technological pformation, while eliminating backward production capacity, we should promote technological progress in the industry, urge enterprises to accelerate industrial upgrading, and realize the pformation from China's major printing and dyeing power to printing and dyeing power.

In the interview,

China Textile Machinery

Zhu Xianmin, deputy director general of the equipment industry association, said that the high temperature and high pressure airflow dyeing machine in printing and dyeing equipment was produced in large quantities.

Compared with the traditional overflow dyeing machine, the high temperature and high pressure airflow dyeing machine has a very small bath ratio, and has the advantages of fast heating up, low energy consumption and small discharge.

According to the experts, the traditional dyeing machine has a water ratio of 1:7, but the airflow machine can be reduced to 1:4. Although the energy consumption of the air turbine is higher, it can save about 25% of the total production cost and reduce the sewage discharge by nearly 40%.

This not only reduces the cost of production, but also reduces environmental pollution.

Realizing short process and multiple intelligentization

Short process

Although it has been discussed for many years in the printing and dyeing industry of China, its process has not been obviously shortened from the whole process of continuous dyeing and printing.

For this reason, Zhu Renxiong, consultant of China printing and dyeing industry association, explained that the printing and dyeing process determines the process of the equipment, and the stability and automation of the domestic dyeing and printing equipment are still low.

When it comes to the demand for printing and dyeing equipment, the relevant person in charge of new textile printing and dyeing (Shaoxing) Co., Ltd. also said that in order to meet the requirements of high-grade, multi variety, small batch, fast delivery, rapid change and rapid change of printing and dyeing products, the demand for new and advanced technology and advanced technology is urgent. It is urgent to use these new technology and equipment to pform or eliminate traditional printing and dyeing equipment, and truly realize cleaner production.

Accordingly, experts have suggested that the current practice in printing and dyeing machinery is to tap the potential of traditional production processes for energy conservation, water saving and emission reduction, and to set up waste heat recovery and utilization system for waste water and waste gas, so as to reduce the water intake of fresh water, and to apply on-line detection and control technology to standardize and optimize printing and dyeing processes, so as to reduce the amount and concentration of wastewater discharge.

Multiple intelligentization is another development trend of domestic dyeing and printing equipment. Printing and dyeing equipment is becoming more and more humanized in terms of performance and operation.

Xu Jiaming, general manager of Fujian Jinjiang poly printing and Dyeing Machinery Co., Ltd., said that the development of new textile printing and dyeing technology and equipment is imperative.

In recent years, Ju Wang has also introduced a series of products of multiple intelligences dyeing and printing equipment. "Microcomputer frequency shift direct burning rotary screen printing machine" has greatly reduced energy consumption on the basis of optimizing the structure of circular screen printing machine, improving automation level and on-line testing and correcting ability. The Da Vinci series printing machine has been controlled and diagnosed by computer for remote control and high-precision magnetic bar printing, with automation reaching a certain level.

The leaping development of China's printing and dyeing equipment has gradually reduced the gap with the world's high-end dyeing and printing equipment. New technology and new technology have produced many fine products of China's dyeing and printing equipment.
