Abstract

L'invention concerne un apprêt pour tissus imperméabilisants, caractérisé par le fait qu'il contient un solvant organique ou de l'eau et une combinaison de deux ou plusieurs composés de silicone dissous dans le solvant ou dispersés dans l'eau. Ladite invention concerne également un tissu imperméabilisant et une matière conférant un effet lustrant et une imperméabilité à long terme, caractérisée en ce qu'elle présente une couche de nontissé imperméable contenant des fibres hydrophiles et hydrophobes, selon un rapport pondéral de 3/7 à 7/3 et un constituant imperméable infiltré dans les espaces entre lesdites fibres, ou en ce qu'elle présente une couche de nontissé imperméable contenant des fibres hydrophobes ainsi qu'un constituant imperméable et un tensioactif tous deux infiltrés dans les espaces entre ces fibres. Cette matière, lorsque qu'elle est utilisée pour essuyer simplement une carrosserie d'automobile après un lavage à l'eau, peut avoir un effet sensiblement lustrant et conférer une brillance et une imperméabilité à long terme.
