Le lyocell est une fibre cellulosique semi synth\u00e9tique fabriqu\u00e9e \u00e0 partir de pulpe de bois d’eucalyptus via un proc\u00e9d\u00e9 en circuit ferm\u00e9 recyclant 99 % des solvants utilis\u00e9s.

Et la diff\u00e9rence entre le lyocell et le Tencel ? Elle est d’ordre commercial.<\/p>\n\n\n\n

    Lyocell\/Tencel : d\u00e9finition et origine<\/h2>\n\n\n\n

    Le lyocell est produit depuis les ann\u00e9es 1990, principalement par le groupe autrichien Lenzing AG<\/strong>, qui commercialise sa version sous la marque d\u00e9pos\u00e9e TENCEL\u2122<\/strong>. Les deux termes d\u00e9signent la m\u00eame fibre : lyocell est le nom g\u00e9n\u00e9rique, TENCEL est la marque<\/strong>.<\/p>\n\n\n\n

    La mati\u00e8re premi\u00e8re est de la pulpe de bois<\/strong>, principalement pr\u00e9lev\u00e9 sur de l’eucalyptus<\/strong> cultiv\u00e9 en for\u00eats certifi\u00e9es FSC<\/a>. Cette pulpe est ensuite dissoute dans un solvant organique (le NMMO), puis fil\u00e9e en fibres, qui seront ensuite lav\u00e9s, s\u00e9ch\u00e9s, teints et enfin tiss\u00e9s dans sa forme final, le Lyocell<\/strong>.<\/p>\n\n\n\n

    Le solvant est quant \u00e0 lui r\u00e9cup\u00e9r\u00e9 et recycl\u00e9 \u00e0 99 % dans un syst\u00e8me en circuit ferm\u00e9. C’est cette boucle ferm\u00e9e qui fait toute la diff\u00e9rence avec la viscose standard<\/a> ou le polyester, qui utilise des produits chimiques lourds<\/a> (disulfure de carbone, soude caustique) tr\u00e8s souvent rejet\u00e9s dans les eaux us\u00e9es fautes d’usines correctement \u00e9quip\u00e9es.<\/p>\n\n\n\n

    Les propri\u00e9t\u00e9s du lyocell<\/h2>\n\n\n\n

    Douceur exceptionnelle<\/strong> : le lyocell est plus doux que le coton et comparable \u00e0 la soie<\/strong> au toucher. Les fibres sont tr\u00e8s fines et r\u00e9guli\u00e8res. Pour des v\u00eatements port\u00e9s \u00e0 m\u00eame la peau (chemises, t-shirts, sous-couches), la diff\u00e9rence se fait imm\u00e9diatement ressentir.<\/p>\n\n\n\n

    R\u00e9sistance \u00e0 l’\u00e9tat humide<\/strong> : c’est la grande diff\u00e9rence avec la viscose. Le lyocell conserve une tr\u00e8s bonne r\u00e9sistance m\u00e9canique m\u00eame mouill\u00e9. La viscose, elle, fragilise ses fibres au contact de l’eau (elle r\u00e9tr\u00e9cit et se d\u00e9forme plus facilement).<\/p>\n\n\n\n

    Thermor\u00e9gulation<\/strong> : les fibres de lyocell absorbent et \u00e9vacuent l’humidit\u00e9 efficacement. Le v\u00eatement reste sec et frais m\u00eame en conditions actives.<\/p>\n\n\n\n

    Antistatique<\/strong> : contrairement au polyester, le lyocell ne g\u00e9n\u00e8re pas d’\u00e9lectricit\u00e9 statique. Avantage pratique pour les tenues professionnelles port\u00e9es toute la journ\u00e9e.<\/p>\n\n\n\n

    Naturellement antibact\u00e9rien<\/strong> : les propri\u00e9t\u00e9s hydrophiles des fibres limitent le d\u00e9veloppement bact\u00e9rien (et donc les odeurs).<\/p>\n\n\n\n

    Tenue de forme<\/strong> : le lyocell froisse moins que la viscose. Il n’est pas infroissable, mais nettement plus stable qu’une viscose standard.<\/p>\n\n\n\n

    Lyocell en textile professionnel : quels usages ?<\/h2>\n\n\n\n

    Le lyocell est surtout pertinent dans des contextes o\u00f9 la qualit\u00e9 mati\u00e8re est un argument de positionnement, pas dans les environnements industriels ou \u00e0 fort taux de renouvellement.<\/p>\n\n\n\n

    Corporate et repr\u00e9sentation<\/strong> : chemises, blouses et polos haut de gamme pour \u00e9quipes commerciales, accueil, direction. Le lyocell habille bien, r\u00e9siste aux longues journ\u00e9es et ne d\u00e9gage pas d’odeurs.<\/p>\n\n\n\n

    Restauration gastronomique et h\u00f4tellerie premium<\/strong> : tenues de salle, vestes de service l\u00e9g\u00e8res. La mati\u00e8re s’inscrit dans un positionnement qualitatif coh\u00e9rent avec un \u00e9tablissement haut de gamme.<\/p>\n\n\n\n

    Marques engag\u00e9es \/ RSE<\/strong> : pour les entreprises qui veulent aligner leur textile avec une d\u00e9marche environnementale r\u00e9elle et v\u00e9rifiable.<\/p>\n\n\n\n

    Ce qui limite son usage<\/strong> : le prix (sup\u00e9rieur au coton et \u00e0 la viscose), la disponibilit\u00e9 plus restreinte dans les catalogues de masse, et sa sensibilit\u00e9 relative \u00e0 la chaleur excessive (pas de s\u00e8che-linge, pas au-dessus de 40\u00b0C).<\/p>\n\n\n\n

    Certifications disponibles<\/h2>\n\n\n\n

    TENCEL\u2122<\/strong> : marque Lenzing AG, garantit une production en circuit ferm\u00e9 avec solvant recycl\u00e9.<\/p>\n\n\n\n

    OEKO-TEX STANDARD 100<\/strong> : certifie l’absence de substances nocives dans le produit final. La plupart des lyocells de qualit\u00e9 sont certifi\u00e9s.<\/p>\n\n\n\n

    ECOVERO\u2122<\/strong> : marque Lenzing pour la viscose \u00e9cologique (m\u00eame producteur, proc\u00e9d\u00e9 interm\u00e9diaire entre viscose et lyocell).<\/p>\n\n\n\n

    FSC<\/strong> : certification sur l’origine du bois utilis\u00e9 pour la pulpe.<\/p>\n\n\n\n

    Pour des achats B2B int\u00e9grant des crit\u00e8res RSE dans le cahier des charges, la certification TENCEL\u2122 + OEKO-TEX<\/a> est la combinaison la plus solide \u00e0 pr\u00e9senter.<\/p>\n\n\n\n

    FAQ<\/h2>\n\n\n\n
    Quelle diff\u00e9rence concr\u00e8te entre lyocell et viscose ?<\/strong>

    Le lyocell est fabriqu\u00e9 en circuit ferm\u00e9 (solvant recycl\u00e9 \u00e0 99 %), r\u00e9siste mieux \u00e0 l’\u00e9tat humide, froisse moins, et a un impact environnemental nettement inf\u00e9rieur. La viscose standard est moins ch\u00e8re mais son proc\u00e9d\u00e9 de fabrication est plus polluant si l’usine n’est pas \u00e9quip\u00e9e. Les deux sont doux : le lyocell est l\u00e9g\u00e8rement sup\u00e9rieur. <\/p> <\/div>

    Peut-on laver du lyocell en machine ?<\/strong>

    Oui, \u00e0 30\u00b0C en programme d\u00e9licat. Pas de s\u00e8che-linge (la chaleur d\u00e9grade les fibres). Repassage \u00e0 basse temp\u00e9rature si n\u00e9cessaire. Pour des uniformes \u00e0 entretien intensif (plusieurs lavages par semaine), pr\u00e9f\u00e9rer un m\u00e9lange lyocell-polyester<\/strong> qui am\u00e9liore la r\u00e9sistance au lavage.<\/p> <\/div> <\/div>\n\n\n\n
