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
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...
"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 main difference between polypropylene and polyethylene is their chemical structure. Polypropylene has a more rigid structure, making it stiffer and more heat-resistant than polyethylene. Polyethylene is more flexible and has a lower melting point. You can also differentiate them by their density, with polyethylene being less dense than polypropylene.
There is no difference between polythene and polyethylene. Polythene is simply another name for polyethylene, which is a common type of plastic material used in many products such as plastic bags, containers, and packaging.
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.
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.
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.
Polyethylene oxide and polyethylene glycol are both polymers made of repeating ethylene glycol units. The main difference between them is their molecular weight. Polyethylene oxide has a lower molecular weight and is a liquid at room temperature, while polyethylene glycol has a higher molecular weight and is a solid or semi-solid at room temperature. Additionally, polyethylene glycol is commonly used in pharmaceuticals and cosmetics, while polyethylene oxide is used in industrial applications.
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.
