PA (polyamide) chemical fiber recycling pelletizing machine is a specialized machine used to process waste polyamide (PA, commonly known as nylon) fibers, fabric scraps, and other waste chemical fiber materials. Through processes such as melting, filtering, extrusion, cooling, and pelletizing, it reprocesses these materials into high-purity, reusable nylon recycled plastic granules.

PA (polyamide): A high-performance engineering plastic widely used in textiles (such as clothing, carpets, and tire cords), engineering plastics, and automotive parts.

Chemical fiber recycling: Specifically refers to the processing of waste materials derived from chemical fibers, such as waste fibers from spinning, broken ends from stretching, and scraps from clothing cutting.

PA Chemical Fiber Pelletizing Line Composition:

1. Sorting and Classification: Separating different types (e.g., PA6, PA66) and colors of PA waste to ensure the purity of recycled materials.

2. Crushing/Shredding: Using a high-powered crusher, large pieces of waste cloth and long filament bundles are shredded into smaller pieces for easier subsequent conveying and melting.

3. Feeding and Conveying: The pre-treated fragments are evenly fed into the main unit via a screw feeder.

4. Melting and Plasticizing: Inside the PA pelletizing machine, the PA fragments are melted into a viscous flow state through electric heating and frictional heat generated by screw shearing.

5. Vacuum Deviation: PA is prone to hydrolysis during melting, producing bubbles and decreasing molecular weight. A vacuum degassing system is crucial; it removes moisture, air, and other small volatile molecules from the melt, significantly improving the quality and viscosity of the recycled material.

6. High-Precision Filtration: This is key to determining the purity and value of the recycled material.

7. Extrusion: The filtered, pure PA melt is extruded into strips (strips) through a screen changer to remove tiny carbonized particles, impurities, and unmelted material.

8. Dehydration and drying: The cut granules are dehydrated by centrifugal dehydrator and vibratory dryer to remove surface moisture and ensure that the finished product is dry.

9. Packaging: The dried recycled PA granules are weighed, packaged, and stored.

PA Raw Material Sources:

Spinning mill waste fibers: Waste products, discarded materials, and substandard yarn cakes generated during PA fiber production.

Textile and apparel scraps: Waste PA fabric and scraps cut from clothing, carpets, and curtain fabrics during production.

Waste fishing nets: PA fishing nets in the ocean are serious pollutants; recycling and granulation can achieve resource recycling.

Engineering plastic waste: Sprues and scraps generated during PA injection molding and extrusion.
