- Abstract
Hawthorn red pigment is one of the most common natural food pigments, which can be used for fabric dyeing. Through the study of the hawthorn red pigment extraction process and the wool fabric dyeing process, the optimum hawthorn red pigment extraction process is: 95% ethanol solvent extraction solution, pH value 2, microwave treatment for 1 min, room temperature extraction for 5 h. Then the hawthorn red pigment extract concentration was set at 50% (owf), dyeing temperature at 85 ℃, dyeing time at 60 min, pH value 4, bath ratio of 1 ∶100 can be used for better dyeing effect directly. At the same time, KAl(SO4)2 · 12H2O, CuSO4 · 5H2O and SnCl were used for pre-mordant dyeing to reduce the effect of hawthorn red pigment dyeing on wool
