Procedure

A phosphorus-containing condensation product was synthesized using 500 g. of 80 % THPS and 25 g. of sodium chloride in the same way as in I-A. Sodium sulfate which formed during synthesis of this condensation product and at neutralization of the agent with sodium hydroxide was removed by filtration before treating the fabric. Treatment was carried out using this condensation product under the same conditions as in Experiment No. 7 of Example 2, with the result that a good hand and excellent flame retardancy which passes the DOCFF 3-71 standard after 50 times washing were obtained.
