Abstract

Procédé pour fabriquer un vêtement imperméable à l'eau à partir de textiles en fibres chimiques, qui comporte les étapes consécutives suivantes : l'étape consistant à assembler par ultrasons qui permet à au moins deux pièces de nappes découpées en fibres chimiques d'être rattachées au niveau des coutures par ultrasons ; l'étape consistant à attacher du ruban de bordurage imperméable à l'eau sur les coutures une fois que le soudage par ultrasons a été exécuté au niveau des lignes de rattachement desdites deux pièces de nappes découpées ; l'étape consistant à aplatir ladite couture à la chaleur, pour aplatir les coutures de rattachement qui ont attaché le ruban de bordurage imperméable à l'eau. La présente invention omet les matériaux auxiliaires, tels que les fils, les agrafes, les adhésifs, ou les pinces ; et omet aussi toute colle ou tout solvant toxique. Le procédé de l'invention ne nécessite aucun préchauffage ni aucune restitution, et ne nécessite pas non plus de grosses quantités d'énergie pour maintenir la température du processus ; il respecte donc l'environnement. La coupe et le soudage ou la couture peuvent être effectués par un procédé par ultrasons indépendant, qui permet d'obtenir des bords très nets. Le présent procédé simple peut être réalisé rapidement, et le vêtement imperméable à l'eau qui en résulte possède les propriétés d'imperméabilité à l'eau désirées, à savoir que le vêtement peut rester imperméable sous une pression d'eau de 3 livres pendant au moins deux minutes.
