How RPET fabric is made

The material in a plastic bottle is too useful to end up in landfill. Just to think, those few plastic bottles chucked into then could be turned into various type of bag for everyday use,   identical to anything in your favourite store! Sounds impressive but how is it actually done?

Below we go through the step by step process that every bottle goes on to be turned into a new fabric:

Plastic bottle collection

Before anything else, the plastic bottles that we will use to create our RPET have to be collected.

Plastic bottle baling

After the bottles are collected they are crushed together into cubes known as “bales” making it easier for them to be transported to a sorting plant.

Sorting

Once the bales arrive at the sorting plant they are broken down and passed through sorting machines to remove anything that has been wrongly recycled. Anything that wrongly slips through the net will affect the quality of the final product, so the sorting process is vital. In high quality sorting centres infrared scanners will be used to find bottles that may look compliant but actually contain impurities such as sports drinks with silicone caps.

Colour sorting

The remaining plastic bottles are now sorted by colour. If you were to leave coloured PET bottles in with clear ones the final colour of the fabric produced would be affected.

Flake chopping and washing

The plastic bottles are now crushed into small flakes by large cutting machines. The flakes now pass through a liquid solution to remove any labels and glue from the original bottle. As a final filtering section, the PET flakes will float on the liquid while any remaining contaminants will sink leaving behind clean, pure PET flakes.

Fiber extrusion

After drying, the flakes are stretched out and then chopped into small pieces known as PET pellets. From there, these pallets can be used for a variety of different purposes.

Yarn spinning and bag manufacturing

These pellets are now passed through a “spinnerate” that heats and then stretches the pellets into very fine string-like fibers. Thousands of these fibers are then tied together, creating the start of a polyester yarn. At this point the fiber will appear fluffy, almost like a cotton bud. The fiber will be smoothed, stretched out and placed on a large reel, ready to be sent to a fabric producer to create a final product.

Final will receive the RPET reels and apply any dye and sent to bag manufacturer to finishes variety of bag.

Since last year (IEA) has published the Net Zero by 2050: a Roadmap for the Global Energy Sector.countries have also introduced relevant policies to achieve zero emissions by 2050.

In the new year, through continuous exploration and efforts to change, our company has also made some changes in some products according to the needs.
As noted that our regular product such as shopping bag ,cooler bag ,drawstring bag ,backpack etc,the RPET can instead of regular material for these product,and it 
also reusable and durable and eco-friendly. Through small changes, continue to promote energy conservation and emission reduction.
