The source of raw materials for recycled polyester sewing thread
The production process of recycled polyester
Sewing thread is as follows:
1. Raw material preparation
Recycled materials: mainly use discarded polyester products, such as plastic bottles, textiles, etc.
Cleaning and Sorting: Recycled materials undergo cleaning and sorting to remove impurities.
2. Melting and filtering
Melting: The cleaned material melts into a liquid state at high temperatures.
Filtration: Remove impurities from the melt to ensure purity.
3. Spinning
Extrusion: Melt is extruded through a spinneret to form fine filaments.
Cooling: The filament solidifies after cooling.
4. Stretching and winding
Stretching: The solidified filaments are stretched to enhance strength and toughness.
Winding: The stretched silk thread is wound onto a spool.
5. Twisting and Splicing
Twisting: Twisting a single thread to increase strength.
Splicing: Multiple threads are combined to form a thicker sewing thread.
6. Staining and post-processing
Dyeing: Stain according to requirements.
Post processing: Perform softening, anti-static and other treatments to enhance performance.
7. Packaging
Packaging: The finished product line is packaged according to specifications and ready for sale.
8. Quality inspection
Testing: Conduct strength, color fastness, and other tests on the finished product to ensure compliance with standards.
summarize
Recycled
POLYESTER SEWING THREAD is produced through recycling, melting, spinning, stretching, twisting, dyeing and other steps, which is environmentally friendly and sustainable.
