Abstract
The natural dye of Asiatic wormwood is extracted,and the optimum extracting method is selected. The dyeing properties are tested, including colorant dissolvability, spectral distribution, thermo-stability, anti-ultraviolet light, resistance of metal ion, resistance to oxidation and reduction, then by using orthogonal test, the effects of dyeing temperature, the amount of mordant, pH, time on K/S, DE and Integ value in the process of bottom chrome method for wool fabrics are researched. Finally, the optimum dyeing process of bottom chrome method is obtained; when the amount of mordant is 1. 4%(o. w. f),pH is 5, temperature is 75℃,dyeing time is 30min. Meanwhile, the soaping fastness and rubbing fastness of wool fabric are tested.关键词
