ABSTRACT:
Phosphoric acid 2 hydroxy ethyl methacrylate ester (PHEM) monomer was polymerized using azobisisobutyronitrile (AIBN) initiator on the surface of cotton fabric with the assistance of anionic surfactant namely dodecylbenzenesulphonic acid sodium salt (DBSA) and cationic surfactant namely cetylpyridinium chloride (CPC) separately by the method of admicellar polymerization. The results showed that coated cotton fabric using cationic surfactant (CPC) has higher content of phosphorous than that of coated fabric using anionic surfactant (DBSA). The burning behaviour of treated cotton fabric was investigated by 450 auto flammability and limiting oxygen index (LOI) tests. The pure cotton fabric burnt to entire length without char formation but coated cotton fabrics did not ignite in auto flammability test. However, the char length of coated cotton fabric using cationic surfactant was very less as compared to that of use of anionic surfactant. Thermal behaviour in nitrogen atmosphere is studied which showed that char yield is increased on using CPC surfactant as compared to DBSA surfactant.
