Application of compressed air in chemical fiber industry

The application of compressed air in the chemical fiber industry runs through the entire process of fiber production, mainly fulfilling the three core functions of power transmission, process control and environmental regulation:

1. raw material processing stage

• Through a gas-driven conveying system, raw materials such as polyester chips and nylon particles are accurately delivered to the melting equipment to avoid dust pollution that may be caused by mechanical conveying.
• Utilize the flow characteristics of compressed air to promote uniform heating of raw material particles during the pre-crystallization process

2. Spinning and forming process

• Provides stable air pressure to the spinning pack to ensure that molten polymer forms a uniform fiber stream as it passes through the spinneret
• The filtered compressed air is transported through the circular blowing system to achieve rapid cooling and solidification of the fiber and control the crystallinity and orientation of the fiber

3. drafting and shaping process

• In a multi-stage drafting device, compressed air serves as a power source to drive the differential motion of the roller, accurately controlling the drawing ratio of the fiber
• Maintain constant tension of the tow during drafting through a pneumatic tensioner to prevent wire breakage or doubling

4. post-treatment process

• Drive the pneumatic braking system of the winder to achieve precise winding and tension control of the silk cake
• During dyeing or functional finishing processes, use compressed air to stir the dye solution or reagent to ensure that the fiber is in uniform contact with the treatment solution

5. Public works supporting facilities

• Provide air source for the dust removal system to remove flying fiber floccules generated during the production process
• Drive pneumatic valves and actuators to achieve rapid adjustment of process parameters
• Maintain positive pressure in the workshop environment to prevent external pollutants from entering the clean production area

The industry’s demand for compressed air has requirements for continuity, stability and cleanliness. Multi-stage filtration and drying treatment are needed to ensure that the air is free of oil, moisture and particulate matter to meet the requirements of chemical fiber products for strength, luster and dyeing properties.
