Hvilken type polyester der bruges i tøj?
polyethylenterephthalat
Polyester er en kategori af polymerer, der indeholder en esterfunktionel gruppe i deres hovedkæde. Som et specifikt materiale henviser det oftest til en type, der kaldes polyethylenterephthalat (PET). Polyestere omfatter naturligt forekommende kemikalier, f.eks. i cutin i planternes neglebånd, samt syntetiske stoffer som polybutyrat. Naturlige polyestere og nogle få syntetiske polyestere er biologisk nedbrydelige, men de fleste syntetiske polyestere er ikke biologisk nedbrydelige. Materialet anvendes i vid udstrækning i beklædning.
polyethylene terephthalate
Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. The material is used extensively in clothing.
