ABSTRACT:
A process for flameproofing cellulosic fabrics which comprises impregnating the fabric with an aqueous solution of a THP salt with or without condensation with a nitrogen-containing compound, and treating the impregnated fabric with ammonia to produce a cured resin, wherein the treatment with ammonia is carried out by passing the impregnated fabric through seals into and out of a closed chamber and in contact with at least one duct located in the chamber and having one or more orifices through which gaseous ammonia is caused to issue and pass through the fabric over its width, the chamber being provided with means to prevent condensed water formed by evaporation and/or chemical action from dripping on to the fabric.
