Abstract
Effect of the pH condition was examined on extraction and dyeing of the yellow and red dyes of safflower. Absorption of dye solution extracted from safflower was changed by pH of solvent. In the case of yellow dyes, cotton and ramie weren't dyed regardless of pH of dye bath, but silks were significantly dyed at pH4. Raw silk showed better dyeability than refined silk. In the case of red dyes, cotton and ramie absorbed red dyes selectively, but silks absorbed yellow dyes more significantly than red dyes. Efficiency of extraction and dyeing of yellow dyes in acidic range were find out higher than that in neutral range. Red dyes was effectively extracted at pH11 and dyed at pH6.
