Silk in 2700: Leizu legend
Read the condition on Silk before the nickname. Year 2700, line “Leizu legend,” figure 2700. Silk 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.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Silk (fibroin + sericin) is a family of grades whose density ~1.34 g/cm³, heat band degrades; no thermoplastic melt, and fire letter combustible protein.
Silk is sold as grades, not as a single substance. Chemistry fibroin + sericin, density ~1.34 g/cm³, heat band degrades; no thermoplastic melt. This atlas treats Silk as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low. Insulation score 34/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: combustible protein. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide. Origin: China Neolithic / Silk Road, China. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: nylon.
The label keeps Silk, 2700, and 2700. “Leizu legend” is the condition on the figure.2700
