Research on the dyeing behavior of wool fabric with natural phytolacca berry dyes

Journal Article (Journal Article)

The natural dyes was extracted from mature Phytolacca berries for wool fabric dyeing, the influence of different dyeing process parameters on the dyeing depth was investigated in the case of direct dyeing, Al3+ as mordant was applied to improve the dyeing fastness, the antibacterial properties of dyed wool fabric was tested. The results showed that: the dyeing depth K/S value increased with the ratio of solid to liquid and tended to flatten when the ratio was 1 : 8. 33. The K/S value increased with temperature, the dyed fabric color changed from red to pale yellow when the temperature was over 60 °C. The K/S value declined with NaCl concentration increased. The K/S had maximum color yield when the pH value was 3.5. Al3+ could improve the washing and rubbing fastness of dyed fabric. The dyed fabric had good antimicrobial properties.
