Sažetak
Cotton is one of the most flammable materials. In the case of fire cotton materials represent a major risk as burning strong and fast. Therefore, it is necessary to make cotton fabric flame retardant. In order to eliminate the use of toxic compounds, especially for cotton flame retardancy, silicate compounds were recently researched. The synergistic effects occurring between water glasses and urea/ammonium dihydrogen phosphate was proved, however the durability of treatment was low. For the purpose of enhancing efficiency and durability, in this research cotton fabrics were modified by mercerization and cationization during mercerization and then treated with the conventional flame retardants urea and ammonium hydrogen phosphate with addition of water glass. The influence of such modification to the flame retardancy of cotton was researched and compared with untreated/bleached cotton. Burning behavior of flame retarded cationized cotton was studied through Limiting Oxygen Index, LOI determination in the LOI Chamber (Dynisco) according to ISO 4589:1996. For better understanding the changes in cotton structure under the heat conditions, the results of thermogravimetric method, TGA (Pyris1, Perkin Elmer) and micro combustion calorimetry, MCC (MCC-2, Govmark) were discussed. As the change in color occurs in FR treatment, fabric degree of whiteness and yellowness index were determined. The achieved results suggested better crosslinking and durability if flame retardants applied to modified cotton fabrics. This effect is more enhanced for cotton fabric cationized during mercerization with reactive polyammonium compound.
