Development trends of dyeing and finishing equipment
The continuous development of fabric fiber varieties has caused huge changes in the variety structure of dyeing and finishing production, thus promoting the development of dyeing and finishing equipment suitable for finishing synthetic fiber fabrics. For example, thermal precision instrument coloring machines, various high-temperature and high-pressure coloring machines, heat setting machines, transfer printing machines, etc. have been used and improved one after another. At the same time, the progress of dyeing and finishing production technology and the improvement of mechanical and electrical design and manufacturing levels have also promoted the improvement and progress of dyeing and finishing equipment. For example, continuous steaming and bleaching machines, continuous pad dyeing machines, jigger dyeing machines, high-speed yarn finishing machines, etc. have all been greatly improved. In addition, the variety and use performance of fabrics for workwear, decoration, industry, national defense and other purposes have become diversified, which has led to newer developments in dyeing and finishing equipment, such as high-temperature and high-pressure airflow dyeing machines. In terms of finishing equipment, it is more prominent, such as foam finishing machine, PU coating finishing machine, multi-functional rolling and electric finishing machine, sanding machine, pre-shrinking machine, etc. At present, the development trend of dyeing and finishing equipment can be summarized as the following aspects.
1. Short-process equipment
The current dyeing and finishing process emphasizes fast and efficient reaction conditions. By optimizing the process, updating equipment, and shortening the equipment process, we can reduce equipment investment costs, reduce production costs, and reduce the factory floor area. , Improve the utilization rate of equipment to improve investment efficiency.
2. The proportion of dyeing and finishing equipment with high quality, suitable for small batches, multiple varieties, and intermittent finishing is increasing. The competition in the international fabric market is becoming increasingly fierce, and dyeing and finishing products are constantly updated. Reasons such as small order quantities, short delivery times, and high product quality requirements also prompt companies to develop high-quality dyeing and finishing equipment suitable for small batches, multiple varieties, and even intermittent finishing.
For example, large-capacity jigger dyeing machines, intermittent overflow jet dyeing machines, and continuous pad dyeing machines suitable for small batch finishing.
3. One machine has multiple functions and can adapt to the requirements of multi-variety sorting
In order to reduce equipment investment and improve equipment utilization, and enhance the adaptability and versatility of the equipment, in recent years, a multi-purpose machine that can adapt to multiple varieties of sorting has been successfully developed. Dyeing and finishing equipment. For example, high-temperature and high-pressure large-capacity jigger dyeing machines that can be used for pre-treatment of small batches of fabrics, steamers that can also be used for baking, multi-functional padding and finishing machines, and heat-setting machines that can be used for woven and knitted fabrics. Full anti-shrinking machine, etc.
4. Low energy consumption, low pollution
Due to the increasingly prominent energy crisis and environmental protection issues, people are paying more and more attention to cleaner production, and low-energy consumption and low-pollution equipment are increasingly used. For example, high-efficiency water washing equipment, small liquor ratio overflow jet coloring machine, air flow coloring machine, foam finishing machine, high-efficiency open-width water press, transfer printing machine, digital printing machine, etc. In addition, high-temperature dyeing and finishing equipment and the hot washing part of some washing machines recycle waste heat. Some high-temperature equipment can also automatically detect the humidity and heat of the hot and humid exhaust gas it discharges, and reduce heat energy consumption to a minimum through computer control.
5. The fabric runs in low tension or loose style
Reduce the tension in fabric finishing, reduce the elongation of the fabric, improve product quality, enhance the adaptability of the equipment to fabric varieties, and make the fabric run in low tension or loose style running in the state. For example, low-tension jig dyeing machines, loop-threading open-width washing machines, rope washing machines and some loose open-width washing machines.
6. Microelectronics technology is increasingly widely used
In order to control the finishing quality, ensure the reproducibility of the process, save energy, reduce labor intensity and strengthen finishing cost management, dyeing and finishing equipment is generally equipped with microcomputers to automatically control process parameters, Finishing procedures and some mechanical actions. For example, automatic color matching and automatic dripping systems, automatic control systems for coloring processes, dyeing factory management systems, etc.
7. Application of new technologies and new processes
With the improvement of mechatronics technology, the progress of mechanical and electrical design and production levels, new dyeing and finishing processes and new technologies have put forward higher requirements for equipment. Some new equipment continues to emerge. For example, microwave coloring machine, high-frequency media drying machine, high-speed centrifugal spray coloring machine, gas coloring machine, digital printing machine, etc.
