Is there a difference between 100% polyester and 100% polyester fabric?

The two are like the same as the pig kidney and the pig kidney. Polyester fiber is the scientific name, the international name (named from its composition), polyester is the trade name of polyester fiber in China (named by type). 100% polyester fiber (polyester) is generally airtight (a little reserved heat dissipation grid), very hot, skirts, pants do not matter, tops, especially sportswear, do not consider, the brand is written with polyester fiber In order to confuse the audience, I don’t understand what I thought was very advanced.
