Title: Extraction of Asiatic wormwood dye and its dyeing processes to wool fabric
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.
