Answer
Polyesters are recycled to make fleece jackets for several reasons:
Used to form fibres: Recycled polyesters can be processed to create new fibers for use in textiles.
Cheaper clothing: Recycling polyester can reduce costs associated with production, resulting in more affordable clothing options.
Stops landfill filling up: By recycling polyesters, we reduce waste sent to landfills, thus addressing environmental concerns.
Less energy required to recycle: Generally, recycling polyester uses less energy than producing new fibres from raw materials.
