The main difference between polyester staple fiber yarn and polyester filament yarn is that polyester staple fiber yarn is made up of chemicals. Polyester filament yarn contains both man-made and natural fibers.
"polyester fiber" consists of individual fibers that are usually at least sever meters, often hundreds of meters, long. In "polyester staple fiber", the fibers have been cut or chopped so that an individual fiber is rarely more than 30 centimeters long.

the difference is in the backbone... if the backbone is unsaturated then it is an unsaturated polyester, if the backbone is saturated then it is a saturated polyester...
This guide will explain the difference between cotton filled and polyester filled bedding sets. Cotton filled quilts are typically more expensive because of the added skill required in making the quilts. 100% cotton quilts are normally heavier than polyester filled quilts because polyester is a less dense fiber. Because of the lighter weight, polyester has more "holes" with which to retain heat. For this reason, polyester quilts are lighter and can be warmer than 100% cotton quilts.

Polyester is used to made synthetic fibers.
Fibre-shelkote distributes vinyl ester resin which is required for underwater usage. Polyester resin is chemically similar to 2 part epoxy, and is much less expensive, but should never be used underwater.
of course its not why ask it is a type of cotton

Wool is a natural fibre grown by animals as fleece; polyester is fabricated from petroleum.
No, cotton is a natural fibre made from the cotton plant, and polyester is a man-made synthetic fabric which is a petroleum-by-product.
