摘要
The improvement in flame retardancy of high loft polyester nonwovens was studied based on two different strategies (1) role of synergistic study of carbon micro/nano particles and flame retardant (FR) finishing agent and (2) role inherent flame retardant fibers in blend. The samples coated with FR chemical finish alone showed maximum resistance for flame propagation, however with more smoke formation. When the samples were coated with carbon micro/nano particles alone, the appearance of distinct flame was found with less amount of smoke formation. The synergistically coated samples revealed intermediate behavior with respect to those samples coated with carbon micro/nano particles alone and FR chemical finish alone. When inherent flame retardant polyester fibers (i.e. Toray Esfron, Trevira CS, Huvis FR) were blended with regular high loft polyester, the formation of flame was found negligible without smoke. However, the samples exhibited higher tendency of melt dripping without formation of char.
