Low energy consumption
The energy conservation of textile machinery is focused on dyeing and finishing equipment because of the great potential in this area. For example, on a flat washing machine with a production capacity of 1000 kg at the time of the table, the fresh influent water required for heating itself with a discharge temperature of 98 ° C can save tens of thousands of dollars in a single shift. By using a jet dyeing machine, the dyeing bath ratio can be reduced from 1:20 to 1:30 in the ordinary dyeing machine to 1:5 to 1:15, and the dyeing time can be shortened by 50%. Although jet dyeing in a machine requires a large capacity pump to increase power consumption, the total energy is still saved. Transfer printing has been applied to production in the 1970s. It is characterized by low emissions, energy saving and less pollution. Solvent sizing reduces water volume and energy consumption.
In addition, the change in the composition of glove machine materials is also a feature of the development of modern textile machinery. Cast iron was originally the main structural material of textile machinery, because it is rich in resources, cheap in price, easy to process, can be cast into complex shapes, relatively corrosion-resistant, and has good shock absorption, but it is gradually being shaped by steel and welded parts. Replaced by alloy die castings, the percentage of weight in each machine is significantly reduced. Wood is also the main structural material of textile machinery. Due to excessive forest deforestation, resources are becoming increasingly scarce and gradually replaced by engineering plastics and light metals. Composite engineering plastics have superior properties not found in wood, such as high strength, corrosion resistance and water resistance. Weather resistant, wear resistant, etc. High-quality steel is also used more as a drive shaft, gear blank, connecting rod, cam and other materials. In order to resist the acid corrosion of the chemical and the high temperature corrosion of the organic matter, the dyeing and finishing machine mostly uses nickel-chromium stainless steel containing molybdenum and titanium as a container, a machine room wall, a guide roller and other parts in contact with the fabric and the medium. Chemical fiber machinery is more widely used as a spinneret, screw extruder, metering pump and other parts in contact with polymers and parts that work in liquids containing organic solvents at high temperatures.
