From the analysis of the current situation of printing and dyeing machinery industry in China, many products are still in the stage of imitation development, and the proportion of independent innovation is low. Although many manufacturers have gained some achievements by cooperating with foreign companies to develop new and high products to seize the market, their product development is basically the same as that of foreign countries, which does not mean independent innovation and does not have their own intellectual property rights. There are also a number of manufacturers through hard training, comprehensively improve product quality, customer trust and recognition, but products without breakthrough innovation, it is difficult to stay in the market for a long time. Therefore, to fundamentally improve the market competitiveness of enterprises, it is necessary to introduce new products with independent intellectual property rights to meet the market needs on the basis of using foreign advanced technologies and integrating the development of market textiles.
Printing and dyeing machinery through practice - recognition - practice - recognition of the cycle process, step by step, gradually improve. At the beginning, only centrifugal spinning was used for rayon filament spinning, and the speed was low and the volume was small. Now, not only centrifugal spinning but also semi-continuous spinning machines are relatively mature, and the full-automatic continuous spinning machines have been successfully trial-produced. The process is shortened, the speed is accelerated and the volume is increased, which meets the development needs of man-made fibers.
It is reported that at present domestic and foreign printing and dyeing machinery industry development trend, is efficient, energy-saving and environmental protection, these three aspects complement each other, indispensable. Productivity wants to develop, raise production efficiency is the most direct means; Energy conservation has reached the stage where measures must be taken. While adopting energy-saving measures and developing productivity, we must also have environmental awareness and pollution treatment. After analyzing the current situation and development trend of China's printing and dyeing industry, the national development and reform commission clearly proposed that "traditional industries should be transformed with informatization and high-tech", which is not only the policy orientation of the development of printing and dyeing industry, but also the policy orientation of the development of printing and dyeing machinery industry.
In recent years, the degree of electromechanical integration of dyeing and finishing and equipment has been improved, and the application scope of electronic technology has been expanded. Emphasis on modularization and building blocks in product design; The electric drive is stable and reliable, and the tension can be adjusted. However, China's dyeing and finishing equipment and foreign advanced level, basically equal in strength. In automatic control and program control board, online monitoring board; Remote monitoring and fault diagnosis technology has been completely solved in China. Quantitative titration, automatic feeding does not match. The problem solving is mainly reflected in: dyeing and finishing equipment process parameters on-line detection technology: in front of the dyeing and finishing processing, mercerizing, dyeing and steaming, finalize the design process, some process parameters on-line detection has been the key technology of printing and dyeing and finishing problems, the main requirement is in dyeing and finishing process, the parameters in the process of rapid change of signal detection, conversion and timely control of the processing parameters, and work stably and reliably.
