duvet est le mat\u00e9riau phare des vestes et des sacs de couchage de trekking et d'alpinisme. Sa l\u00e9g\u00e8ret\u00e9, sa compressibilit\u00e9 et son isolation thermique en ont fait le choix privil\u00e9gi\u00e9 des alpinistes. Cependant, sa principale faiblesse est bien connue : lorsqu'il est mouill\u00e9, il peut perdre jusqu'\u00e0 90% de sa capacit\u00e9 d'isolation en raison de l'effondrement de sa structure.<\/p>\n\n\n\n<p>Pour comprendre cela visuellement, imaginez que vous versez de l'eau sur votre veste en duvet. Les fibres s'agglutinent et forment des amas qui n'emprisonnent pas l'air, perdant ainsi leur capacit\u00e9 \u00e0 retenir la chaleur. C'est ce que nous appelons \"l'affaissement\".<\/p>\n\n\n\n<p>En r\u00e9alit\u00e9, il faut faire une grosse erreur pour qu'il s'effondre compl\u00e8tement. Lors de treks sous une pluie persistante, m\u00eame un duvet de 650 FP trait\u00e9 avec du DWR (<em>Hydrofuge durable<\/em>) conserve 70% de son volume apr\u00e8s 8 heures d'humidit\u00e9. En r\u00e9alit\u00e9, le v\u00e9ritable ennemi n'est pas l'eau directe, mais plut\u00f4t le&nbsp;<strong>l'humidit\u00e9 accumul\u00e9e lors de longues exp\u00e9ditions<\/strong>&nbsp;o\u00f9 il peut perdre jusqu'\u00e0 15% par jour de pouvoir isolant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u00c9volution : duvet hybride (o\u00f9 la plume rencontre le polyester)<\/h2>\n\n\n\n<p>La principale avanc\u00e9e r\u00e9side dans les m\u00e9langes strat\u00e9giques :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fibres synth\u00e9tiques \"anti-effondrement<\/strong>Les sph\u00e8res de polyester minuscules (comme le PrimaLoft Cross Core) agissent comme un \u00e9chafaudage microscopique. <\/li>\n\n\n\n<li><strong>Nanotechnologie hydrofuge<\/strong>Les traitements aux nanoparticules cr\u00e9ent une barri\u00e8re mol\u00e9culaire dans le panache.<\/li>\n<\/ul>\n\n\n\n<p>Face \u00e0 cette faiblesse historique, l'industrie a \u00e9volu\u00e9 vers des solutions hybrides. Les v\u00eatements produits aujourd'hui m\u00e9langent duvet naturel et fibres synth\u00e9tiques, ce qui r\u00e9duit consid\u00e9rablement le risque d'affaissement.<\/p>\n\n\n\n<p>Aujourd'hui, gr\u00e2ce aux m\u00e9langes hybrides, il est possible de porter des v\u00eatements et des vestes qui n'incorporent que 10% de fibres synth\u00e9tiques, ce qui est suffisant pour \u00e9viter un affaissement total et assurer un s\u00e9chage relativement rapide du v\u00eatement en cas d'humidit\u00e9 mod\u00e9r\u00e9e.<\/p>\n\n\n\n<p>Ce faible pourcentage de fibres synth\u00e9tiques agit comme un \"squelette\" qui emp\u00eache le duvet de s'agglom\u00e9rer compl\u00e8tement, ce qui lui permet de conserver jusqu'\u00e0 60% de sa capacit\u00e9 isolante, m\u00eame lorsqu'il est mouill\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">L'imperm\u00e9abilisation des doudounes est-elle vraiment efficace ?<\/h2>\n\n\n\n<p>Les vestes en duvet sont \u00e9galement dot\u00e9es de traitements d\u00e9perlants avanc\u00e9s qui leur permettent de r\u00e9sister \u00e0 de fortes pluies pendant de longues p\u00e9riodes sans \u00eatre tremp\u00e9es. Un traitement DWR (<em>Hydrofuge durable<\/em>) peuvent g\u00e9n\u00e9ralement r\u00e9sister \u00e0 une pluie mod\u00e9r\u00e9e pendant 60 minutes sans trop compromettre l'isolation. Toutefois, ces vestes ne doivent pas \u00eatre consid\u00e9r\u00e9es comme imperm\u00e9ables \u00e0 l'usage. Elles sont d\u00e9perlantes, mais en cas d'exposition prolong\u00e9e ou d'immersion accidentelle, leurs performances peuvent chuter de mani\u00e8re significative.<\/p>\n\n\n\n<p class=\"has-theme-palette-8-background-color has-background\">J'ai personnellement test\u00e9 des vestes dot\u00e9es de ces technologies, et bien que les performances soient \u00e9tonnantes lors de courtes temp\u00eates, vous ne devriez jamais vous passer d'une couche ext\u00e9rieure imperm\u00e9able telle qu'une bonne veste de pluie pour prot\u00e9ger de mani\u00e8re ad\u00e9quate votre isolation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Duvet ou fibres synth\u00e9tiques : lequel choisir ?<\/h2>\n\n\n\n<p>Voici la question cl\u00e9 : qu'est-ce qui est le mieux, le duvet ou le synth\u00e9tique ?<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>En bas :<\/strong> L\u00e9g\u00e8ret\u00e9, compressibilit\u00e9 et isolation sup\u00e9rieures dans des conditions s\u00e8ches.
