The lyocell fibers were treated by electron beam (E-beam) irradiation to improve carbonization yield. The properties of E-beam irradiated lyocell fibers were analyzed by SEM, FT-IR, XPS and TGA. The E-beam irradiated lyocell fibers were carbonized at 800 ℃ during 1 h and the carbonization yield was measured. The lyocell fibers were decomposed at the same time and cross-linked by E-beam irradiation. The decomposition and crosslinking degree of lyocell fibers was increased as increasing E-beam absorbed dose. Therefore, initial decomposition temperature of lyocell fibers was decreased and the carbonization yield was increased as increasing E-beam absorbed dose. The carbonization yield of lyocell fibers by 1500 kGy E-beam irradiation were increased by 25.6% than that of pure lyocell fibers. |
