Flame-Retardant Properties and thermal Pyrolysis Behavior of Selected Flame-Retardant Cotton Cellulose

난연처리 면섬유의 난연성능과 열분해거동에 관한 연구

The flame-retardant properties and thermal behavior of cotton finished with some selected flame retardants, organic nitrogen compound, organic phosphorus compound and inorganic halogen compound etc. were investigated. Total add-on of finish were determined and flammability properties were evaluated by the 45$^{\circ}$ angle method. Thermogravimetric analysis were used to study the thermal behavior of the cotton during pyrolysis. The thermogravimetric analysis curves were evaluated quantitatively for activation energy, total weight loss and char remaining after pyrolysis, and peculiarity point of pyrolysis. A study of the kinetics of decomposition for these systems indicates that activation energy was found to decrease with increasing flame retardency and an inverse relationship between activation energy and the residue remaining after pyrolysis was observed. Further, it has been observed that the addition to cellulose of any of the compounds lowers the onset temperature of decomposition and the temperature at which the first major weight loss begins, and the temperature decrease varies from compound to compound.
