Improved anti-oxidation properties of Lyocell fiber achieved by phosphorus compound |
| 초록 |
The anti-oxidation behavior of Lyocell fibers during flame-retardant treatment as a function of the effects of a phosphorus compound was explored. Di-ammonium-hydrogen phosphate (DAHP) was observed to reduce the thermal degradation rate of the Lyocell fibers and increase the char yield; DAHP also increased the limiting oxygen index via a first-order relationship with the char yield. The integral procedure decomposition temperature (IPDT) increased significantly, and the activation energy increased by a certain factor, indicating a slow degradation pathway involving dehydration, rearrangement, formation of carbonyl groups, evolution of carbon monoxide and carbon dioxide, and formation of a carbonaceous residue for the flame retardancy of Lyocell fibers. |
