Modification of cotton material with prcursors of silicon alkoxides for improved flame retardancy

The application of natural zeolite in cotton finishing bath suggested that this complex silicone compound may have a considerable influence on cotton flammability. Silicone has excellent thermal stability and high heat resistance with very limited release of toxic gases during the thermal decomposition. In this paper cotton material has modified with sol-gel method. Material was treated with two precursors of silicon alkoxides - 3-Aminopropyltrietoxysilane and 3-Methacryloxypropyltrimethoxysilan. These two precursors were combined with conventional flame retardants to improve their initial flame retardancy. For better understanding the changes in cotton structure under the heat conditions limited oxygen index (LOI), thermogravimetric method (TGA), micro combustion calorimeter (MCC) was used.
