Thermal Analysis Techniques as a Primary Sign for Fire Retardancy of New Textile Back-coating Formulations

New back-coating formulations containing new flame-retardant systems were prepared and applied on cotton textile samples. The flammability properties of cotton samples were improved sharply by applying the new back-coating formulations. The mechanical properties of cotton samples was totally destroyed when using the flame retardant A 6 (chloro dimalonylurea phosphine oxide). By using the new back coatings B 11 ((A 6 ) chloro dimalonylurea phosphine oxide 30% with sodium carbonate 20%) and B 12 ((A 6 ) chloro dimalonylurea phosphine oxide 20% with sodium carbonate 30%) the mechanical properties and also the flammability properties of cotton samples have been improved. The thermal analysis techniques give a fast and good indication about the expected flammability properties of back-coated cotton samples.
