棉 is one of 32 materials in this atlas, grouped under textiles: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare 棉 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.

棉 (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).
棉 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 棉 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.
Origin: Indus / New World domestication; mill 18th c., India / Americas / Lancashire. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: polyester.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 54/100. Ask which scrap, which certificate, which year.
