ABSTRACT:
The permanence of the flame-resistant finish of fibre materials, in particular those based on cellulose, is improved if a phosphono compound which contains an N-methylol group. is used together with an organic carboxylic acid as the finishing agent. If oxalic acid in particular is used as the carboxylic acid, the finished fibre material can be stored in a damp environment for a prolonged period of time without intermediate washing being necessary. The tendency of the finish to hydrolyse in a damp atmosphere is reduced by using the organic carboxylic acid instead of a mineral acid.
