Sažetak
Due to potential toxicity risks and environmental issues associated with FR cotton treatments, there is a need for their substitute with some new green alternatives. Phytic acid (PA), as a principal phosphorus store in plant, and its salts from renewable sources, such as bran and seeds, have been used as an environment friendly replacement for commercial phosphorus based flame retardants in laboratory conditions. In this work thin films of polyelectrolytes, cationic branched polyethylenimine (BPEI) and anionic phytic acid (PA) were successfully deposited on cotton via Layer-by-Layer (LbL) deposition in order to reduce the flammability of cotton. Altering the number of BPEI/PA bilayers (1, 5, 10) and the concentration of PA sodium salt hydrate in aqueous solution (5, 10, 50 wt %) at the same BPEI concentration (1 wt %) the results of LOI and TGA curves indicated the reduction of flammability of all LbL treated cotton fabrics in relation to untreated cotton. The highest content of PA (50 wt %) gave the best FR performance to cotton (LOI 29 %) while the increase in number of bilayers (from 5 to 10, at the same PA concentration, had no significant influence on flammability of cotton (table 1).
