Polyethylene terephthalate (PET) fits the definition of a polyester so the name is redundant. I think PETP is simply an old abbreviation for PET.
what is the main difference between polyethylene and polyesters what is the main difference between polyethylene and polyesters
"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...
dun noe
density of HDPE
Thr answer is They dont Have the Same sPelling
of course its not why ask it is a type of cotton
hi, polyester is a synthetic fibre derived from coal, air, water and petroleum. polyester fibres are formed from a chemical reaction between an acid and alcohol.
Wool is a natural fibre grown by animals as fleece; polyester is fabricated from petroleum.
they are the same but just with different ways of saying it.
Polyethylene terephthalate is a thermoplastic polymer resin of polyester. It is used to make beverage, food, and other liquid containers, as well as creating other resins from combinations with fiberglass. It is commonly known by its brand name Dacron.
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.
