Cotton in 1950s: Wash-and-wear resins
Read the condition on Cotton before the nickname. Year 1950s, line “Wash-and-wear resins,” figure 8. Declared reaction class in this atlas: combustible fibre (treatments vary). Assemblies still need resistance tests.
Scores compare Cotton with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Cotton (cellulose (C6H10O5)n) is a family of grades whose density ~1.54 g/cm³ fibre, heat band chars ~150 °C+, and fire letter combustible fibre (treatments vary). Cotton is sold as grades, not as a single substance. Chemistry cellulose (C6H10O5)n, density ~1.54 g/cm³ fibre, heat band chars ~150 °C+.
This atlas treats Cotton as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low (textile still air). Insulation score 40/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: combustible fibre (treatments vary). Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
The label keeps Cotton, 1950s, and 8. “Wash-and-wear resins” is the condition on the figure.1950s
