Polyester in 1941: Terylene · 596
Read the condition on Polyester before the nickname. Year 1941, line “Terylene,” figure 255. Carbon passports must name the route (virgin, scrap, bio, hydrogen).
This atlas treats Polyester as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low solid; fabrics trap air. Insulation score 50/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: melts and drips unless FR. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Whinfield & Dickson 1941 / DuPont Dacron, United Kingdom / US. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: nylon. Circularity mark 34/100. Ask which scrap, which certificate, which year.
Related atlas entries, a short glossary, and three threads that keep Polyester honest. The polyamide rival: tougher wet, different dye class. The blend that made drip-dry shirts. Olefin cousin, different melting and hand. When polyester’s melt-drip is unacceptable. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating.
The label keeps Polyester, 1941, and 255. “Terylene” is the condition on the figure.1941
