Polyester is manufactured by one of several methods. The one used depends on the form the finished polyester will take. The four basic forms are filament, staple, tow, and fiberfill. In the filament form, each individual strand of polyester fiber is continuous in length, producing smooth-surfa...
The raw material for polyester fleece is polyester, which is made from two petroleum products: terephthalic acid and ethylene glycol. Some or all of the polyester yarn may be recycled from soda bottles. Various dyes also make up raw materials, as well as finishing substances such as Teflon or...
These materials are generally utilized when the desired polyurethane is going to be used to make flexible foams or thermoset elastomers. Polyester polyols may also be used as a reacting species in the production of polyurethanes. They can be obtained as a byproduct of terephthalic acid production...
