At present, the general trend of the development of Stenter and equipment technology is: to develop in terms of environmental protection, energy saving, time-saving and high-efficiency, short process, and pay attention to new technologies such as waterless processing technology, non-plate printing technology, and low-temperature plasma treatment; Another important trend is the widespread use of automation technology. The transmission system adopts an AC frequency conversion multi-unit synchronous speed regulation system; in terms of control systems, programmable controllers or industrial computer control are widely used, and online parameter monitoring is widely used, which improves the The degree of automation greatly improves the process stability and reproducibility. Dyeing and finishing production presents the development trend of short process and high efficiency. The short process and high efficiency process equipment that are compatible with it mainly include cold pad pretreatment, wet short steam pretreatment, coil mercerizing, cold pad dyeing, wet Short steam dyeing, coil dyeing and high liquid feed device, etc.
Printing and dyeing machinery manufacturers 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 functions, but also in terms of stability and reliability, it is not inferior to imported equipment. With the continuous introduction of high and new technology such as digital online detection and control technology, computer network technology into the manufacturing of printing and dyeing equipment, the automation of domestic printing and dyeing equipment is continuously improved, energy consumption and water consumption are gradually reduced, and the three major problems of color difference, weft deviation and shrinkage have been solved. Gradually improve, and the stability and leakage problems have been effectively resolved. As printing and dyeing equipment companies not only pay attention to ideas, but also come up with practical methods from actions. As a result, the one-time drive rate of domestic equipment has also increased a lot.
Printing and dyeing machinery progresses step by step and gradually improves through the cyclic process of practice-knowledge-re-practice-re-knowledge. When the complete set of man-made staple fiber equipment is equipped with the Xinxiang, Nanjing and Hangzhou chemical fiber plants, the annual production capacity of one line is 3,400 tons. Now the annual production capacity of equipment for Weifang, Dandong and other chemical fiber plants is 80,000 tons. Man-made fiber filament spinning started only by centrifugal spinning, and the speed was low and the package was small. Now not only centrifugal spinning but also semi-continuous spinning machines are relatively mature. Fully automatic continuous spinning machines have also been successfully trial-produced, and the process is shortened. The speed of the vehicle is accelerated and the package is enlarged to meet the development needs of man-made fibers.
Compared with foreign printing and dyeing machinery and equipment, the domestic Flat Screen Printing Machine has little difference in appearance and basic functions for most conventional products. The main difference lies in the stability and reliability of the product. After the domestic equipment arrives at the printing and dyeing factory, the installation time is long due to factors such as the design and manufacturing quality and the defect of parts, and there are many on-site rework; after the trial operation, the commissioning period is long due to the inconsistency of the electromechanical and printing and dyeing process requirements, and the failure rate is high in the early stage of the start-up. It not only causes great losses to users, but also adversely affects the reputation of the equipment, thereby reducing the market competitiveness of the product. However, most of the imported equipment has a short installation and commissioning cycle, a high success rate of a start-up, stable and reliable, low failure rate, and convenient operation and maintenance. Some users would rather pay a high price to buy imported equipment, spend money to buy with peace of mind, and buy benefits, rather than buy domestically produced equipment.
