Abstract:

Based on tea pigment dyeing process with mordant of wool fabric, screening of the dyeing processes with different metal mordants were carried out, and dyeing properties of wool fabric before and after ultraviolet radiation were compared. The results showed that K/S value and dye fixation of wool fabric dyed by tea pigment dyeing process with CuSO4 were higher than that in other processes, and improving dyeing properties of wool fabric treated by ultraviolet radiation was confirmed according to the comparison of experimental data. Therefore, the ultraviolet radiation was combined with tea pigment dyeing process with CuSO4 to improve the tea pigment dyeing effects of wool fabric. The tea pigment dyeing process with CuSO4 of wool fabric treated by ultraviolet radiation was discussed during single factor analysis, these optimized scopes of ultraviolet radiation time, CuSO4 content and dyeing time were selected, then the process was optimized by using the three-factor quadratic general rotary unitized design. The optimum process was determined as follows (dosage/on weight of fabric (o.w.f)):ultraviolet radiation time 9 min, tea pigment 5.0%, CuSO4 1.7%, HCOOH 2.0%, pH=3.5~4.0, 95℃, dyeing time 60 min, bath ratio 1:50. Compared with conventional tea pigment after chrome process, the dyeing effects of wool fabric dyed by the optimum process, which possessed of lower metal mordant content, were better.
