Abstract

L'invention concerne un procédé de préparation pour un matériau de base de tissu dégradable et recyclable. Le matériau de base de tissu comprend une chaîne (1), une trame (2) et une suspension épaisse (3). Le procédé comprend: la préparation d'une chaîne (1) et d'une trame (2) au moyen d'une fibre de Tencel comme matière première; la préparation d'un tissu brut au moyen d'un procédé de tissage à la machine; et la réalisation d'un traitement artisanal sur le tissu brut de sorte que le tissu brut devienne un matériau de base de tissu avec une suspension épaisse (3) sur deux faces. Ce matériau de base de tissu présente une performance de résistance à la chaleur relativement souhaitable, un faible pourcentage d'allongement lors de l'utilisation et une planéité élevée sur la surface et n'a pas tendance à gondoler. Ce produit peut être recyclable une fois inefficace ou peut être dégradé par des micro-organismes dans le sol sans générer de matériau nocif dans une condition d'environnement naturel, ce qui permet d'éviter la pollution de l'environnement. En outre, une matière première de fibre de Tencel est un matériau de conifère qui est recyclable et présente des coûts faibles.
