Printing and dyeing machinery has adapted to the needs of human development.

At present, the overall development trend of printing and dyeing machinery and equipment technology is as follows: It is developing towards environmental protection, energy conservation and consumption reduction, time-saving and high efficiency, and short process flows. New technologies such as waterless processing technology, plateless printing technology, and low-temperature plasma treatment are highly valued. Another important trend is the extensive application of automation technology. The drive system adopts an AC variable frequency multi-unit synchronous speed regulation system. In terms of the control system, programmable logic controllers or industrial computers are widely used for control, and online parameter monitoring is commonly applied, which has significantly improved the automation level of dyeing and finishing equipment and greatly enhanced the process stability and reproducibility. The dyeing and finishing production shows development trends such as short process flows and high efficiency. The short process flow and high-efficiency process equipment that are adapted to this trend mainly include cold pad-batch pretreatment, wet short steam pretreatment, cloth rolling mercerizing, cold pad-batch dyeing, wet short steam dyeing, pad-roll dyeing, and high liquor delivery devices, etc.  

       Printing and dyeing machinery manufacturing enterprises can only embrace future development with new technologies. At present, compared with foreign printing and dyeing equipment, domestic printing and dyeing equipment not only has little difference in appearance and basic usage functions, but also is in no way inferior to imported equipment in terms of stability and reliability. With the continuous introduction of high-tech technologies such as digital online detection and control technology and computer network technology into the manufacturing of printing and dyeing equipment, the automation level of domestic printing and dyeing equipment has been continuously improved, the energy consumption and water consumption have gradually decreased, and the three major problems of color difference, weft skew, and shrinkage have been gradually improved. Moreover, the problems of stability and leakage have been effectively solved. Printing and dyeing equipment enterprises not only attach great importance to these aspects in their thinking, but also take practical measures in their actions, which has significantly increased the first-time startup rate of domestic equipment.  

       Printing and dyeing machinery progresses step by step and improves gradually through the cyclic process of practice - cognition - re-practice - re-cognition. When equipping the chemical fiber factories in Xinxiang, Nanjing and Hangzhou with the complete sets of equipment for man-made fiber staple fibers, the annual production capacity of one production line was 3,400 tons. Now, the equipment provided for chemical fiber factories in Weifang, Dandong and other places has an annual production capacity of 80,000 tons. In the beginning, for the spinning of man-made fiber filament, there was only centrifugal spinning, which featured low spinning speed and small package size. Now, not only is centrifugal spinning available, but semi-continuous spinning machines have also become relatively mature, and fully automatic continuous spinning machines have been successfully trial-produced. The production process has been shortened, the spinning speed has been increased, and the package size has been enlarged, meeting the development needs of man-made fibers.  

       When comparing domestic printing and dyeing machinery and equipment with foreign ones, for most conventional products, there is not much difference in appearance and basic functions. The main gap lies in the stability and reliability of the products. After domestic equipment arrives at the printing and dyeing factory, due to factors such as design and manufacturing quality and missing parts, the installation time is often long and there is a lot of on - site rework. After entering the trial operation, due to the inconsistency between the mechanical and electrical aspects and the requirements of the printing and dyeing process, the debugging cycle is long and the failure rate in the early stage of startup is high. This not only causes great losses to users, but also has a negative impact on the reputation of the equipment, thus reducing the market competitiveness of the products. In contrast, most imported equipment has a short installation and debugging cycle, a high success rate of one - time startup, is stable and reliable, has a low failure rate, and is convenient for operation and maintenance. Some users would rather pay a high price to buy imported equipment to get peace of mind and efficiency, rather than purchase domestic equipment.
