In the case of fiber products, flame-retardant properties can be achieved by applying a polyethylenimine and a phosphonic acid to the fiber products or to precursors thereof. The fiber products may be sheet-like textile structures in the form of woven fabrics or they may be yarns or fiberboards. The precursors of the fiber products may be aqueous fiber suspensions which are further processed to give paper or fiberboards.

Avec les produits fibreux, des propriétés ignifuges peuvent être obtenues par application d'une polyéthylénimine et d'un acide phosphonique sur les produits fibreux ou sur des précurseurs de ces produits. Les produits fibreux peuvent être des structures textiles de type en feuilles sous forme de tissus tissés ou peuvent être des fils ou des panneaux de fibres. Les précurseurs des produits fibreux peuvent être des suspensions fibreuses aqueuses soumises à un traitement supplémentaire en vue de l'obtention de papier ou de panneaux de fibres.
