Coton Le coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

| Résumé : |
Moisture-wicking, quick-drying, ultra-lightweight — polyester and other synthetic fibers like polyamide and elastane set the stan¬dards expected from high-performance clothing. Despite obvious downsides —these fibers do not feel as nice on the skin and start to smell a lot faster than their natural counterparts — synthetics have radically reshaped the global textile supply chain. Today, synthetics account for roughly two-thirds of global fiber production and the majority of that is polyester. These fabrics are made crude oi I and manufactured by burning high quantities of natural gas. Presently, the relatively low costs of polyester garments do not factor in the high environmental toll of the fossil fuel industry at all stages in the supply chain.
But cotton, once dominant, has not been able to compete. None of the natural materials — including hemp, linen, and wool — could be manipulated to make possible sweat-wicking, mechanical stretch, abrasion resistance, or quick-drying properties. Natural fi bers could not be formed and shaped the same way synthetics could. Because of this, it was considered impossible to make nat¬ural fabrics with the performance versatility of synthetics. |
