<p>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.</p> |
