Sažetak
The use of ultrasounds in the textile wet processing has been found to have great utility since they alter the fibre structure increasing their absorption as well as raising the diffusion coefficient of chemical molecules. Starting from these premises, the aim of this study was to investigate the effects of alkaline ultrasound pre-treatment on the cross linking of non-halogenated hydroxyl functional organophosphorus (Non-halogenide HFOP) flame retardant agent and citric acid (CA) as a bonding agent on the cellulose material. Flame retardance was tested using Limiting oxygen index (LOI) technique according to ISO 4589-2. The thermal and physico chemical properties of the so obtained flame retardant samples were characterized by thermogravimetric analysis, coupled thermal gravimetric - Fourier transforms infrared technique (TG-FTIR) and Fourier transforms infrared spectroscopy (FTIR). The results indicate that a more stable bonding between cellulose and flame retardant agents was achieved in the sample which was pre-treated in an ultrasound alkaline bath.
