Abstract
The composition for in situ treatment of textiles or textile products comprises in admixtures: (a) an ammonium salt or mixture of ammonium salts having flame retardant properties, (b) a water-soluble amide decomposing at a temperature of 100.degree. C. to 200.degree. C. to give ammonia, and (c) aqueous acid in a concentration insufficient to cause degradation of a fabric by the composition when applied thereto.
Claims11
A flame retardant composition for in situ treatment of textiles and textile products comprising in admixture:
- 9.5 to 15.5 percent by weight of a component consisting of at least one ammonium salt having flame retardant properties, 2.0 to 3.0 percent by weight of a water-soluble amide which will decompose to give ammonia when heated to a temperature of 100.degree. C. to 200.degree. C., and aqueous acid in a concentration of 1.5 to 2.0 percent (by weight) of the composition and with the pH of the composition being 3 to 4.5 thereby ensuring that the composition is sufficiently diluted for application to a fabric without degrading it.
