羊毛 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 羊毛 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.
よくある質問
Is 羊毛 non-combustible?
Declared reaction class in this atlas: better than commodity synthetics in many apparel tests. Assemblies still need resistance tests.
Does 羊毛 insulate?
Thermal mark 72/100 versus the atlas. Conductivity note: low when lofted.
What is the density band?
~1.31 g/cm³
How is it made?
Origin story: Neolithic sheep; merino Spain; industrial Yorkshire (Near East → Spain → Australia).
Can it be recycled?
Circularity mark 58/100 — editorial, route-specific.
Typical melting or failure heat?
chars; does not melt-drip like PE
What should it be paired with?
cotton: Cellulose comfort without keratin’s odour story.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
