回收塑料瓶如何变成抓绒面料

Used PET bottles are sorted, washed, and shredded into tiny flakes before melting.
The molten plastic is forced through fine nozzles to form continuous polyester filaments.
These threads are then stretched, cooled, and cut into short fibers for spinning.
During weaving, fibers get brushed to raise soft, insulating loops—creating fleece texture.
One jacket may use 12–20 recycled bottles, depending on size and thickness.
Recycling this way uses 50% less energy than making new polyester from oil.
Brands label garments with bottle counts to show environmental impact transparency.
Though durable, fleece sheds microfibers in wash—so special bags now help trap them.
