The Identification of Polyester Fibers in Forensic Science
A polyester fiber is by definition one composed of linear macromolecules comprising at least 85% (by mass) of the chain of an ester of a diol and terephthalic acid . In 1941 it was discovered in the laboratories of the Calico Printers Association in Lancashire, England that fibers could be spun from polyethlene terephthalate (PET). I.C.I. Ltd. began production in 1948 under the name “Terylene,” and production was expanded to a large scale in 1955. DuPont began to produce a polyester known as Fiber V in the U.S.A. in 1950. This fiber subsequently became known as Dacron® and was produced in quantity from 1953 onwards .
