蚕丝 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 蚕丝 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.
常见问题
Is 蚕丝 non-combustible?
Declared reaction class in this atlas: combustible protein. Assemblies still need resistance tests.
Does 蚕丝 insulate?
Thermal mark 34/100 versus the atlas. Conductivity note: low.
What is the density band?
~1.34 g/cm³
How is it made?
Origin story: China Neolithic / 蚕丝 Road (China).
Can it be recycled?
Circularity mark 50/100 — editorial, route-specific.
Typical melting or failure heat?
degrades; no thermoplastic melt
What should it be paired with?
nylon: The filament that stole stockings and chutes.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
