| Abstract | ||||
| Diffusion as a function of temperature of benzimidazole and chromene dyes. It is well known that a carrier is not required for the dyeing of polyester at temperature exceeding 100◦ C (high temperature dyeing process). This is due to the fact that the diffusion coefficient increases with rising temperature. The extent of this increase was found by measuring exhaustion curves at different temperatures. | ||||
