The promising application of citric acid (CA) and 1,2,3,4-butanetetracarboxylic acid (BTCA) for the purpose of flame retardant (FR) finishing was investigated. Both polycarboxylic acids (PCAs) were applied as an environmentally friendly binder in a reaction with N-hydroxymethyl-3-dimethylphosphonpropionamide. The results were compared with a conventional agent based on melamine formaldehyde. The purpose of melamine resin is to provide nitrogen in order to enhance the flame retarding performance of the treated fabric through synergism with phosphorus. In our previous investigations it was determined that the best catalyst to be used with PCAs is sodium hypophosphite monohydrate (SHP). The FR effectiveness was tested according to the ISO 6940 method, as well as with the limiting oxygen index (LOI) technique according to ASTM D 2863-97. Moreover, the thermal degradation of raw cotton and FR treated cotton fabrics was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).

Badano zastosowanie kwasu cytrynowego i 1,2,3,4-butanotetrakarboksylowego (BTCA) w celu uzyskania anytpalnej preparacji. Obydwa kwasy polikarboksylowe zastosowano jako przyjazne środowisku związki wchodzące w reakcje z 3-dimetylofosfopropionoamidem. Wyniki porównano z konwencjonalną preparacją z udziałem formaldehydu melaminy. Celem zastosowania żywicy melaminowej jest wprowadzenie azotu w celu zwiększenia niepalności. Antypalność materiałów badano zgodnie z normą ISO 6940, jak również metodą Ograniczonego Indeksu Tlenowego (LOI) zgodnie z normą ASTM D 2863-97. Dodatkowo obrabiane materiały poddano analizie termo grawimetrycznej oraz różnicowej kalorymetrii skaningowej.
