Abstract
The influences of extraction temperature, time and solid to liquid ratio on extraction effect of natural dye from water chestnut were discussed by orthogonal test. The effects of dyeing temperature, time and liquor ratio on silk fabric dyeing were investigated. The extraction conditions of natural dye from water chestnut and its dyeing conditions with the extract on silk fabric were optimized. Three dyeing methods, pre- mordant, meta- mordant and post- mordant dyeing were compared. The optimum conditions for the ex⁃traction were: extracting at 60 ℃ for 60 min, 1∶20 of solid to liquid ratio. The optimum dyeing conditions were:dyeing at 80℃for 30 min, 1∶45 of liquor ratio, and pre- mordant dyeing was the best method.关键词
