Production Process from PET Bottle to Recycle Polyester Yarn

1.preparation

The production process of recycled polyester begins with the processing of used bottle. Firstly, it is necessary to clean, crush, and sort the waste plastic bottles to remove impurities and dirt, ensuring the quality of the raw materials.

2. Bottle melting

After being crushed, cleaned plastic bottles will form bottle fragments. Next, put the bottle slices into the melting box for heating and melting, transforming them into molten material.

3. Spinning

The melt undergoes a series of treatments, such as filtration, pressure, etc., to form a thin and elongated smear. Then, the smear is stretched into fine filaments, a process called spinning.

4. Stretching

The stretching of polyester is divided into two methods: hot stretching and cold stretching. Hot stretching refers to stretching fibers at high temperatures to form finer filaments. Cold stretching refers to stretching fibers at room temperature to make them stronger and stronger.

5. Encryption

Finally, the fibers of varying thickness are densified and evenly arranged to form long polyester filaments. Finally, the polyester fibers are fed into the textile machine to produce various polyester fiber products.

So the total production process from used bottle to recycle polyester Yarn is:

Summary:

The production process of recycled polyester yarn from used bottles involves multiple steps, from raw material processing to the final production of polyester filament products, which require careful operation and technical support. By recycling and reusing waste plastic bottles, high-quality polyester fibers can be produced, which not only reduces environmental pollution but also contributes to environmental protection.
