The change in the composition of textile machinery materials is also a characteristic of the development of modern textile machinery
Chemical fiber machinery widely uses heat-resistant and acid resistant high-grade alloy steel to make spinnerets, screw extruders, metering pumps, and other parts that come into contact with polymers and work in liquids containing organic solvents at high temperatures.
In addition, changes in the composition of textile machinery materials are also a characteristic of the development of modern textile machinery. Cast iron was originally the main structural material for textile machinery because of its abundant resources, low price, easy processing, ability to cast complex shapes, relatively corrosion resistance, and good shock absorption. However, it has gradually been replaced by steel parts, welded parts, and alloy die-casting parts, and its weight percentage in each machine has significantly decreased. Wood used to be the main structural material for textile machinery. Due to excessive deforestation and increasing resource scarcity, it has gradually been replaced by engineering plastics and light metals. Composite engineering plastics have excellent properties that wood does not have, such as high strength, corrosion resistance, water resistance, weather resistance, wear resistance, etc. High quality steel is also more commonly used as materials for drive shafts, gear blanks, connecting rods, camshafts, and more. In order to resist the acidic corrosion of dyes and the high-temperature corrosion of organic matter, dyeing and finishing machinery often uses nickel chromium stainless steel containing molybdenum and titanium as containers, machine room walls, guide rollers, and other parts in contact with fabrics and media. Chemical fiber machinery widely uses heat-resistant and acid resistant high-grade alloy steel to make spinnerets, screw extruders, metering pumps, and other parts that come into contact with polymers and work in liquids containing organic solvents at high temperatures.
