Where is the low pollution of textile machinery?

Textile machinery is a variety of machinery and equipment needed to process natural fibers or chemical fibers into textiles. Textile machinery has low pollution, which is reflected in:

The change of material composition of textile machinery is the characteristic 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, is relatively corrosion-resistant, and has good shock absorption, but it is gradually welded by section steel parts. The percentage of weight in each machine is significantly reduced by replacing parts and alloy die castings. Wood was also the main structural material of textile machinery. Because of excessive deforestation and shortage of resources, it was gradually replaced by engineering plastics and light metals. Composite engineering plastics have more excellent properties than wood, such as high strength, corrosion resistance, water resistance, climate resistance and wear resistance. In order to resist acid corrosion and high temperature corrosion of dyes and chemicals, stainless steel containing molybdenum and titanium is often used in dyeing and finishing machines as containers, machine room walls, guide rollers and other parts in contact with fabrics and media. Chemical fibre machinery is more widely used in heat-resistant and acid-resistant alloy steel for spinneret, screw extruder, metering pump and other parts in contact with polymers and parts working in liquid containing organic solvents at high temperatures.

Now the whole society is advocating environmental protection and pollution-free, and textile machinery should be low pollution in the times.
