How can synthetic fleece be made from pop bottles?
Fleece is made of polyester, a petroleum-based synthetic that can be spun into fibers or molded into plastic.
The bottles are separated by color, sterilized and then crushed, chopped and melted.
The melted plastic is extruded through a shower-head type device, producing fibrous polyester strands. Those strands are stretched to thin out and strengthen them.
The strands are woven into fleece or other materials, such as T- shirts and sweats
