Not long ago, the State Council officially issued the "notice on Further Strengthening the elimination of backward production capacity" (hereinafter referred to as the "notice"), pointing out that China will focus on nine industries to eliminate their backward production capacity on schedule, including the printing and dyeing industry. The notice requires that backward production process equipment with high energy consumption and water consumption be eliminated by the end of 2011. Under the situation of energy shortage, increasing shortage of water resources and deteriorating environmental pollution, solving the energy conservation and emission reduction of printing and dyeing enterprises and the reuse of water resources are the key to promote the adjustment and transformation of the printing and dyeing industry to achieve sustainable development. A large part of this task falls on the shoulders of printing and dyeing equipment

in recent years, China's printing and dyeing equipment enterprises have closely followed the pace of industry development and independently developed a number of printing and dyeing equipment that can help enterprises save energy and reduce emissions, especially the technical level of some equipment that used to rely on imports for a long time has been significantly improved

cold transfer printing equipment: improve rapid response ability

at the 2009 Shanghai International Textile Industry Exhibition, the cellulose fiber cold transfer printing equipment jointly developed by Zhejiang gross company and Shanghai Changsheng textile company attracted a lot of attention

this new device combines the cold transfer digital inkjet technology with the cold transfer printing technology, first inkjet directly on the cold transfer inkjet medium, and then transfer the pattern to the cloth. Using the cold transfer digital printing technology, the pattern can be directly transferred to the cloth with paper through the high-precision cold transfer printing machine, that is, the transfer paper and the fabric enter the transfer device at the same time, and instantly contact the cloth at room temperature, but transfer to achieve one-time printing. It solves the problem that digital is now in the three-month trial operation stage, and the printing nozzle is easy to be blocked due to fiber wool and slurry powder on jacquard fabrics, strong concave convex style of fabric organization and other fabrics

due to the high fixation rate, in the cold transfer digital ink-jet printing process, the amount of dye per square meter of printed cloth is only 6 grams, saving 40% of the amount of dye. At the same time, due to the reduction of the amount of digital printing material and water consumption for washing, the cold transfer printing technology has more prominent characteristics in terms of energy saving and low consumption, which can save 2/3 of water consumption, and the recovery and utilization rate of discharged water can also reach 90%, saving energy by 65%

according to relevant experts, the transfer printing process has quickly occupied the market share of many traditional direct printing processes because of its flexible return size and realistic printing effect, especially its advantages in environmental protection because it produces almost no sewage. Most of the transfer printing uses disperse dyes. At high temperature, it uses the high-temperature sublimation characteristics of disperse dyes to transfer to chemical fiber fabrics, which is called heat transfer printing. The application limitation of this process is that it can only print chemical fiber fabrics

cellulosic fiber cold transfer printing technology uses reactive dyes, which can color any cellulosic fiber fabric. Its dye transfer rate can reach bentler Sigri. It will develop to 95% in the direction of self-control production line, and the dye transferred to the fabric also has a fixation rate of nearly 90%. Although it also needs washing after fixation, it produces much less sewage than traditional direct printing. Cold transfer printing is also not limited by the structure of fabrics, whether woven or knitted fabrics, thick or thin fabrics, can be transferred. For some thick and tight fabrics, double-sided two-layer printing paper can also be used to transfer printing at the same time, so as to achieve the effect of double-sided printing. Because it can adopt the principle of four color separation, and can reflect the photo effect of rich layers and infinite colors on the fabric, the exquisite effect of its printing can be comparable to that of computer spray printing. At the same time, the use of cold transfer printing technology can simplify the printing and dyeing process, and increase the market rapid response ability of enterprises even in the extremely high temperature range; It can be produced in small batches to meet the market demand for personalized and high-quality fabrics

digital continuous dyeing machine mercerizing machine: realize efficient production

the energy-efficient and environmental friendly digital continuous mercerizing machine and continuous dyeing machine developed by Jiangsu Hongqi printing and Dyeing Machinery Co., Ltd. passed the appraisal of scientific and technological achievements and won the second prize of the science and technology progress award of China Textile Industry Association in 2009. Experts believe that the successful development of high-efficiency, energy-saving and environmental friendly digital continuous dyeing machines and mercerizing machines will help speed up the application of new energy-saving and water-saving technologies in China's printing and dyeing industry, and realize the transformation of pollution prevention and control in the printing and dyeing industry from end-to-end treatment to source prevention

continuous mercerizing machine and continuous dyeing machine are the main equipment in the continuous printing and dyeing production line of cotton woven fabrics, which play a vital role in the printing and dyeing quality of textiles. Continuous mercerizing machine is used in the mercerizing process of fabric pretreatment. Stretching and dealkalizing the fabric soaked in concentrated caustic soda solution under tension can effectively improve the adsorption capacity, gloss and strength of the fabric. However, the continuous mercerization production consumes a lot of alkali and water, and the concentration of alkali liquor fluctuates greatly, which is easy to cause product quality instability. Continuous dyeing machine is the machine with the largest production load in dyeing processing. Its composition is very complex. Each unit machine has varying degrees of impact on fabric dyeing quality. It is difficult to control the whole machine, and the energy and water consumption are high

the energy-saving and environment-friendly digital continuous mercerizing machine and continuous dyeing machine developed by Hongqi printing and dyeing machinery company realize the detection and control of process parameters in the whole process of mercerization. The mechanical speed is arbitrarily set within the range of 10 ~ 90m/min, and has the functions of automatic alkali concentration detection, automatic alkali distribution, pH automatic detection, distribution humidity detection, and automatic shutdown, water and steam shutdown; A Thread Micro stretching device is added between the straight roll alkali leaching area and the mercerization stability area to control the weft shrinkage of the fabric within 2%; The rear section of the straight roll mercerizing area adopts the multi rolling point pressurization method and is equipped with a high-efficiency rolling car, which can effectively achieve low rolling stock ratio; The machine can adopt wet mercerization or hot mercerization process, which can effectively save water and steam, and the mercerization effect is good; The machine is equipped with a condensate and heat recovery system, which can supply water in reverse flow throughout the whole process and wash with oscillating water, without waste water discharge in the middle; Caustic soda can be reused and recycled, saving 40% of caustic soda, with remarkable effect
