Studies on the Flame Retardancy of Cotton/Synthetic Fiber Blended Fabrics

혼방 직물의 방염가공에 관한 연구

This study is to improve the flame retardancy of textile based on cotton and Polyester blended fabrics finished with Fyrol 76, N-methyolacrylamide and TBPP. In case of the cotton and polyester blended fabric used in the study, treated fabric containing 5%∼5.5% phosphorous, 1.5%∼2% nitrogen and 7.5%∼8% brome satisfies the requirements of DOC-FF 3∼7l. TGA analysis shows that speed and temperaure of thermal decomposition are lower than that of untreated fabric. Tearing strength and ball bursting strength are decreased as the concentration of treating solution is increased.
