Title (EN) TREATMENT OF FIBROUS SUBSTRATES TO IMPART REPELLENCY, STAIN RESISTANCE, AND SOIL RESISTANCE
(FR) TRAITEMENT DE SUBSTRATS FIBREUX VISANT A LEUR CONFERER DES PROPRIETES HYDROFUGES, ANTI-TACHES ET ANTI-SALISSURES
Abstract:
(EN) A process is described which imparts exceptional antisoiling, anti-staining and repellent properties to carpets. The process makes use of a water-based exhaustion process wherein the water-based treating solution contains (1) glassy fluorochemical material, glassy hydrocarbon material, or combinations thereof; (2) a stainblocking material; (3) a polyvalent metal salt, acid, or combinations thereof; and (4) water. Subsequent to exhaustion, the wet treated carpet is heated, usually in a steaming step, rinsed, and dried in a dry heat oven.
(FR) L'invention concerne un traitement conférant aux tapis d'excellentes propriétés anti-taches, anti-salissures et hydrofuges. Ce traitememt comprend un procédé par épuisement à base d'eau, la solution aqueuse contenant ce qui suit: (1) un composé fluoré vitreux, un hydrocarbure vitreux ou leurs combinaisons; (2) une substance anti-taches; (3) un sel métallique polyvalent, un acide ou leurs combinaisons; et (4) de l'eau. Après ce procédé par épuisement, le tapis humide est chauffé, généralement à un stade de vaporisage, puis rincé et séché dans un four à chaleur sèche.
