In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging. [citation needed] Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).
Polyester was one of the most popular fibers used in fashion in 2017, found in about 60% of garments in retail stores and equalling about 21.3 million tons of polyester fiber. [32] There was a 157% increase of polyester clothing consumption from 2000 to 2015. [ 32 ]
Polyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. [1] As a specific material, ...
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

Polyester is much more resistant to polymer degradation than either nitrate or triacetate. Although triacetate does not decompose in as dangerous a way as nitrate does, it is still subject to a process known as deacetylation, often nicknamed "vinegar syndrome" (due to the acetic acid smell of decomposing film) by archivists, which causes the ...
Polyester is inherently flame retardant, and therefore doesn't flare up when applied to various tests. Any amount of heat delivered within a long enough time interval will have no impact on the fabrics' integrity while a limited amount of heat delivered within short enough time interval may ignite or melt the fabric.
Coolmax is the brand name for a series of polyester fabrics developed and marketed by The Lycra Company (formerly Dupont Textiles and Interiors then Invista).. Coolmax is marketed as "moisture-wicking" and "breathable".
When PTFE is heated above 450 °C the pyrolysis products are different and inhalation may cause acute lung injury. [2] Symptoms are flu-like (chills, headaches and fevers) with chest tightness and mild cough.
