Claims (10)

1. Procédé d'apprêtage ignifuge ignifugation d'une matière fibreuse cellulosique, le cas échéant teintée et azurée caractérisé en ce que:
(a) on applique et on fixe sur les fibres un produit de condensation de chlorure de tétrakis (hydroxymé- thyl)-phosphonium avec de l'urée, un produit d'auto- condensation de chlorure ou dihydroxyde de tétrakis (hydroxyméthyl)-phosphonium ou bien un amide d'acide diméthyl- ou diéthylphosphono-propionique N-méthylolé en tant qu'agent ignifugeant,
(b) on post-lave et on sèche le matériau et
(c) on post-traite le matériau ainsi obtenu avec de l'ammoniac liquide.
2. Procédé selon la revendication 1, caractérisé en ce qu'en plus de l'agent ignifugeant, on incorpore un agent formant l'aminoplaste ou un précondensat d'aminoplaste.
3. Procédé selon la revendication 2, caractérisé en ce qu'on utilise comme agent ignifugeant un amide d'acide diméthyl- ou diéthylphosphono-propionique N-méthylolé en présence d'une méthylolée, éventuellement éthérée avec du méthyle ou de l'éthyle, en tant que précondensat d'aminoplaste.
4. Procédé selon la revendication 1, caractérisé en ce qu'en plus de l'agent ignifugeant, on utilise ou moins un agent d'infroissabilité, un agent hydrophobe et/ou un agent assouplissant.
5. Procédé selon l'une quelconque des revendications 1 à 4, caractérisé en ce que l'on fixe l'agent ignifugeant sur le matériau textile, selon le procédé de thermofixation, en séchant le matériau fibreux à 60 à 100° C et en le soumettant à un traitement thermique à 130 à 180°C pendant 0,5 à 10 minutes.
6. Procédé selon l'une quelconque des revendications 1 à 5, caractérisé en ce que on post-lave le matériau fibreux avec une solution aqueuse qui contient un agent liant les acides et qui contient éventuellement un agent d'oxydation et on sèche le matériau à 60 à 100°C.
7. Procédé selon l'une quelconque des revendications 1 à 6, caractérisé en ce que l'on post-traite le matériau fibreux avec de l'ammoniac liquide au plus à -33°C, le cas échéant sous tension.
8. Procédé selon la revendication 7, caractérisé en ce que l'on élimine l'ammoniaque, après le post-traitement, par étuvage du matériau fibreux ou bien par de la chaleur sèche.
9. Procédé selon la revendication 7, caractérisé en ce que l'on soumet le matériau fibreux, après le post-traitement sous tension, à un retrait mécanique.
10. Procédé selon l'une quelconque des revendications 1 à 9, caractérisé en ce que l'on utilise, comme matériau fibreux cellulosique, des mélanges de fibres de cellulose avec au plus 70% en poids de fibres synthétiques.
