Patent

CA 2487067

The present invention relates to a fluorochemical composition for rendering fibrous substrates oil repellent, water repellent and/or stain or soil repellent. Additionally, the invention also relates to fluorochemical compositions for providing stain release or soil release properties to fibrous substrates. In particular, the present invention relates to fluorochemical compositions that contain a fluorinated polyether compound that can be obtained by reacting an isocyanate component with a particular isocyanate reactive fluorinated polyether compound and a stain release compound. The invention further relates to a method of treating the fibrous substrate with the fluorochemical composition.

La présente invention concerne une composition fluorochimique permettant de rendre des substrats fibreux oléofuges, hydrofuges et/ou anti-taches ou anti-salissures. De plus, l'invention concerne également des compositions fluorochimiques conférant des propriétés de détachage ou d'élimination de salissures aux substrats fibreux. La présente invention concerne notamment des compositions fluorochimiques qui contiennent un composé polyéther fluoré qui peut être obtenu par réaction d'un constituant isocyanate avec un composé polyéther fluoré réactif d'isocyanate particulier et un composé présentant une aptitude au détachage. L'invention concerne encore un procédé de traitement du substrat fibreux à l'aide de ladite composition fluorochimique.
