Coton 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 Coton 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.

Introduction approfondie

Deep dive: Coton

Coton (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).

What “the material” actually is

Coton 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 Coton as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

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.

How it is made and used

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.

Market and circularity

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.

Questions fréquentes

Is Coton non-combustible?

Declared reaction class in this atlas: combustible fibre (treatments vary). Assemblies still need resistance tests.

Does Coton insulate?

Thermal mark 40/100 versus the atlas. Conductivity note: low (textile still air).

What is the density band?

~1.54 g/cm³ fibre

How is it made?

Origin story: Indus / New World domestication; mill 18th c. (India / Americas / Lancashire).

Can it be recycled?

Circularity mark 54/100 — editorial, route-specific.

Typical melting or failure heat?

chars ~150 °C+

What should it be paired with?

polyester: The blend partner that dries faster and sheds microfibres.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
