ABSTRACT:
Mixtures comprising compounds of the formula ##STR1## wherein A is either NH.sub.2 or N=P(NH.sub.2).sub.3, provided at least one A is N=P(NH.sub.2).sub.3, have been found to be good flame-retardants for material made from cotton or polyester-cotton having about 30 to 70% by weight cotton. Conveniently the material can be treated with an aqueous solution containing a sufficient amount of said mixtures and the material dried to make the material self extinguishing. Then the treated and dried material is cured at a sufficient temperature to bond said compounds to the material. Alternatively and usually preferably the drying and curing can be accomplished as a single operation. The treatment solution can additionally contain auxiliary treatment agents to make the material more durable to washing.
