    Current printing and dyeing machinery should be how to adjust the product structure, how the future development of domestic printing machinery, these problems do not only concern the government, but also industries and enterprises should care about.

    Although in recent years abroad increased demand for high-grade fabric, small quantity and variety of the production model is being respected, but in the foreseeable future, China will remain a large number of middle and low production printing and dyeing industry, woven and knitted fabrics. Therefore, the industry believes that the future development of the domestic printing machinery should focus on large-scale production to meet demand, taking into account the small-scale production needs.

    Accounted for 80% of total domestic middle and low fabric fabrics, the most economical and most effective mode of production is continuous production. Large quantities of woven fabrics, knitted fabrics need continuous dyeing equipment for processing, thus increasing continuous dyeing production line performance is still the main theme of the future development of printing and dyeing machinery.

    Traditional printing and dyeing equipment space is limited

    The current domestic continuous dyeing and printing machinery in the process layout and mechanical structure can be traced back to 74-type printing equipment, the type of equipment is mainly used for cotton, polyester woven fabrics of continuous production, printing and dyeing machinery industry is a milestone in the development process , generated by its theory, data and structural features are still in use, followed by the development of new products, and more with this type of equipment.

    In 1996, China in the 74-type printing equipment developed on the basis of a new generation 96-type wide cotton, polyester dyeing and finishing equipment, 96 printing and dyeing equipment, the main advantage is greatly improved mechanical and electrical integration, with AC variable speed motor replaced the SCR DC motor drives, so synchronization performance greatly improved, and the first will be dyeing process parameters online detection and control system included in the R & D series, the first time the concept of energy efficiency and reliability into product development. Today, printing and dyeing products chromatic aberration, skew and shrink three chronic problem greatly improved than a decade ago, thanks in large part to a market share of 60% of the domestic printing equipment development.

    In recent years, as the main body of machine-made fabric printing and dyeing machinery continuous dyeing machinery constantly improve quality, improve function at the same time, has entered a period of slow development, new products appear slower pace. From the overall situation, domestic continuous flow of woven fabric dyeing and printing equipment has been finalized, the majority of machine process and 74 are substantially the same type of equipment to meet the requirements of most domestic dyeing process, is a "universal" type device processes, future period of time is unlikely to change; whereas most machines and units combined printing and dyeing machinery machines mechanical structure adopted from 96 type equipment in recent years, will not change much. By the dyeing process, the traditional mode of production and manufacturing costs, and many other factors, woven fabric dyeing and printing machinery continuous development of ideas to be bound, so that new ideas and new concepts difficult to produce. Now, advances in printing and dyeing equipment must get rid of the traditional development thinking, not just stare at the structure of woven fabric dyeing and printing equipment to find ideas.

    On the current status of China's printing machinery industry point of view, the development of online testing dyeing process automation and control technology, continuous knitted fabric dyeing and printing machinery and related technologies as well as to achieve continuous production line printing energy, water and cleaning products such as restructuring of production ideas, the development of the next 10 years is feasible, is also based.

    Future restructuring ideas

    Dyeing process automation line detection and control techniques are used to enhance the performance of printing machinery, printing and dyeing industry to solve the traditional high consumption, high emissions. The technology that can be used in woven fabric, the fabric can also be used for other continuous production, great development potential, the development of hot spots in recent years, but the domestic line measurement and control technology and equipment imported products compared to the gap significantly.

    "Eleventh Five-Year" period, China Textile Machinery Equipment Industry Association, under the impetus of China in the printing line detection and control technology has made gratifying achievements, with the basis for further development.

    Now pre-processing to continuous dyeing and finishing process can get a lot of nodes have been monitoring domestic equipment, either as a new factory equipment configuration can also be used for old machine.

    In the dyeing automation, Changzhou Hongda, Hangzhou Kaiyuan, West Andrew High-tech enterprises to develop and with alkali concentration detection systems, dye distribution system, tension measurement and control systems and other products welcomed by the market, which will lead the domestic printing and dyeing machinery the depths of the digital field.

    Currently dyeing line detection and control technology in place is far from development, printing and dyeing equipment, only limited information is also in stand-alone table. The future of digital technology will open the traditional printing and dyeing industry, an unprecedented situation: digital technology to make operation easier, process reproducibility and a success rate will be much higher; sophisticated distribution system to use can improve processing quality, can also save costs and reduce the pollution caused by waste chemicals; printing machine vision system will allow precise finish at high speeds, minimizing waste cloth; workshop level, plant-level information networking and cost, quality, production , unified monitoring of energy consumption will be realized.

    Continuous dyeing knitted fabric can effectively reduce the traditional batch production of the high energy consumption, high water consumption and high emissions problem, with better demand prospects. Continuous development of the knitted fabric dyeing machines and with the corresponding technology, including the development of the specific content of a continuous open width knitted fabrics and bleaching equipment, silk printing equipment and washing equipment, expanded printing machine, setting machine woven fabric dyeing equipment varieties adaptability, forming a continuous dyeing knitted series devices.

    Our continuous dyeing and printing on knitted fabric series equipment R & D in the "Eleventh Five-Year" period has started, gradually resolved curling, tension and other issues, the big drum, with a strong spray of continuous washing machine has successfully developed and put into production, bleaching devices are also being developed, with a representative of the manufacturing companies have Jiangyin Fuda Printing Machinery Co., Ltd., Jiangsu Red Printing and Dyeing Machinery Co., Ltd.. Shaoyang Textile Machinery Company is currently developing amorphous high dyeing machines and West Anderson Automation Engineering Co., Ltd. developed rotary screen printing machines can adapt to the production of knitted fabrics.

    Energy, water and clean production are solved and dyeing industry must continue the task of the future continuous scouring and bleaching equipment, mercerizing machines, continuous dyeing and printing machines such as washing machines can be equipped with wet processing equipment recycling line waste water filtration system and high-temperature waste heat recycling system, so taking less fresh water, less sewage, saving steam consumption and reduce costs; setting machine and drying room can be equipped with a variety of heat recovery, strengthening the body wall insulation to reduce heat loss and improve thermal efficiency; while in the industry to promote alkali, hydrogen peroxide concentration distribution systems and real-time detection dyes metering and distribution systems, to achieve accurate delivery of chemicals, reduce the waste caused by chemical contamination.

    In addition, to achieve energy-saving and clean production printing can also broaden thinking, other areas will mature technology and equipment used for dyeing production lines, such as the ultrasonic techniques and devices used for washing, you can save energy, improve efficiency and washing fastness. Developed for the printing and dyeing wastewater treatment system, the physical treatment, chemical treatment, biological treatment, electro-chemical treatment and membrane separation filtration treatment technology integration, enabling integration of printing and dyeing wastewater treatment.

    Developed to meet the individual needs of equipment

    In addition to continuous dyeing machinery need to be given attention, the intermittent printing machinery can not be ignored. To meet the market demand for personalized textiles, from the 1990s, a small quantity and variety of the popular modes of production, and promote the development of batch dyeing machines. "Eleventh Five-Year" period, China batch dyeing machines focus on the development of low liquor ratio of airflow dyeing machine, Shaoyang Textile Machinery Company after 10 years of efforts, successfully developed multi-tube airflow dyeing machine, the minimum liquor ratio less than 1:4. The future will continue to exist flow dyeing machine high demand, printing and dyeing equipment manufacturing enterprises should develop bath ratio no higher than 1:1 10 products.

    In addition, the development of wool fabric dyeing and finishing equipment is also feasible.

   Now get together on a woven fabric dyeing and printing equipment business too, growing homogenization of products, more and more low technical threshold, profits increasingly thin, but who are unwilling to try new products out first because, although very hard dry However Shumenshulu and woven fabric dyeing and printing equipment needs always exist. Wool fabric dyeing and finishing equipment to stop the development in our country more than ten years, the latest device models or MB-type, or even N-type hair dyeing and finishing equipment and production, domestic market fundamentals such equipment occupied by European manufacturers. Wool fabric dyeing and finishing equipment for the manufacture of high quality requirements, difficult process, but the volume is small, domestic manufacturing enterprises reluctant to touch. The past two years China has been trying to design and manufacture enterprise of such equipment, such as Wuxi Star Satellite Machinery Co., Ltd. has developed for worsted woolen fabrics and high-speed milling combined washing and milling machine washing, etc., which come on printing and dyeing industry said to be a good thing.

    In addition to machine the outer fabric, printing and dyeing machinery restructuring and areas that can be tapped, many types of fabric is still not applicable to specialized equipment, many areas still blank, to be printing and dyeing machinery manufacturing enterprises to be discovered.
