Recycled PA Yarn
The production process of environmentally friendly nylon monofilament mainly includes the following steps:
1. Raw material selection: Select high-quality nylon resin as raw material, which is the basis for producing high-quality environmentally friendly nylon monofilament.
2. Drying treatment: Nylon resin is easy to absorb moisture during the production process, so it needs to be dried to ensure its stability during the melting process.
3. Melt extrusion: Put the dried nylon resin into the extruder and melt it into liquid through high temperature and high pressure.
4. Cooling molding: Extrude the molten nylon resin through the mold, and then cool it with cooling water to solidify it.
5. Stretching and shaping: Stretch the cooled nylon monofilament to arrange its molecular chains neatly and improve its strength and toughness.
6. Heat treatment: Heat treat the stretched nylon monofilament to eliminate its internal stress and improve its stability.
7. Winding and packaging: Wind the heat-treated nylon monofilament, then package it, and finally ship it out of the factory.
The quality of environmentally friendly nylon monofilament is mainly judged from the following aspects:
1. Appearance: high-quality nylon monofilament has a smooth surface, uniform color, and no impurities and defects.
2. Strength and toughness: high-quality nylon monofilament has good strength and toughness and is not easy to break.
3. Dimensional stability: high-quality nylon monofilament can maintain good dimensional stability under various environmental conditions.
4. Weather resistance: high-quality nylon monofilament has good weather resistance and can be used in various harsh environments.
5. Environmental performance: high-quality environmentally friendly nylon monofilament should meet relevant environmental standards and contain no harmful substances.
Features:
Good elasticity, good wear resistance, light texture, good electrostatic hygroscopicity, adapting to the rapid development of modern manufacturing industry.
Packaging:
Paper tube, edge tube, trumpet tube, I-tube. Net weight is adjustable between 0.8-10.0kg
