Interestingly, whereas on the surface there seems little family resemblance between plastic bottles and polyester fabric, in fact they have the same background: Both are processed from PET. Therefore, polyester fibers can be made not merely by starting with what is known in the industry as “ virgin ” petroleum material, they can also be “ reverse ” manufactured from recycled PET bottles.
有趣的是，看似不搭軋的寶特瓶和聚酯纖維，其實「系出同門」，同樣是由 PET 聚合物加工製成，因此聚酯纖維除了可從業界俗稱的「virgin」石油原物料裂解、提煉、化合產製，當然也可由回收寶特瓶「反向」再製。
