Abstract

L’invention concerne une substance liquide de finition de tissu pour tuer les moustiques, son procédé d’application et les produits fonctionnels désirés. Le liquide comprend un pesticide et/ou un insectifuge à hauteur de 0,05-40,00%, un liant à hauteur de 5,00-40,00%, un agent de réticulation à hauteur de 0,025-1,50% et le reste est composé d’eau (pour atteindre 100%), tous ces chiffres étant en pourcentage de masse. Le pesticide et l’insectifuge sont des insectifuges aqueux d’une teneur effective de 1%-50%, et le liant est un liant aqueux d’une teneur solide effective de 40%-50%. Ledit procédé se caractérisée en ce que, après la préparation du liquide de finition de tissu et l’immersion du tissu, on règle la pression des rouleaux et l’on introduit le tissu dans un séchoir à un débit de liquide contenu contrôlé de 30-150%. La température de séchage est comprise entre 60 et 250 ºC. L'invention concerne également un produit textile comprenant un produit de tissu fibreux que l’on finit avec ledit liquide ou bien selon ledit procédé suggéré dans la présente invention.
