(EN) CELLULOSIC TEXTILE MATERIALS

Abstract
(EN)
Flame-resistant modified lyocell fibre is provided which has a limiting oxygen index (LOI) of at least 36, a phosphorus content of at least 3 % by weight and a tenacity of at least 10 cN/tex, or an LOI of at least 32, a phosphorus content of at least 2 % by weight and a tenacity of at least 20 cN/tex. A flame-resistant cellulosic textile material is produced by treating a cellulosic textile material comprising lycoell fibre with a phosphoric acid and an acidic salt or ester thereof and a nitrogen-containing basic compound such as urea. The tendency to fibrillation of a lyocell textile material is reduced by treatment of the textile material with a phosphoric acid or an acidic salt or ester thereof and a nitrogen-containing basic compound.

Fibre lyocell modifiée résistant au feu qui possède un indice limite d'oxygène (LOI) d'au moins 36, une teneur en phosphore d'au moins 3 % en poids et une ténacité d'au moins 10 cN/tex, ou un LOI d'au moins 32, une teneur en phosphore d'au moins 2 % en poids et une ténacité d'au moins 20 cN/tex. Un matériau textile cellulosique résistant au feu est produit par traitement d'un matériau textile cellulosique comprenant des fibres lyocell avec un acide phosphorique et un sel ou ester acide dudit acide phosphorique et un composé basique contenant de l'azote, tel que de l'urée. On réduit la tendance à la fibrillation d'un matériau textile lyocell en traitant ledit matériau textile avec un acide phosphorique ou un sel ou ester acide dudit acide phosphorique et un composé basique contenant de l'azote.
