The invention provides a process for making permanent stain resistant polyamide carpets with light color. The process comprises dyeing a low amine end and cationic dyeable polyamide carpet with acid dyes, and imparting stain resist compositions onto the carpet. In addition to stain resist compositions, a fluoro-chemical is also applied to improve soil resistance. The resulted carpet displays a built-in permanent anti-stain and anti-soil resistance after many shampoo-washes.
L'invention concerne un procédé pour rendre des tapis en polyamide légèrement colorés résistants aux taches de manière permanente. Le procédé comprend la coloration d'un tapis en polyamide à extrémités amines faibles et colorable cationiquement avec des colorants acides, et l'application de compositions d'enduit résistant aux taches sur le tapis. En plus des compositions d'enduit résistant aux taches, un composé fluoré est également appliqué pour améliorer la résistance aux salissures. Le tapis résultant présente une résistance aux taches et aux salissures intrinsèque et permanente, même après de nombreux nettoyages au shampoing.
