The invention discloses an efficient
dyeing process for improving the anti-felting performance of
wool fabric. The method includes the following steps that 1), the
wool fabric is added into a nano
titanium dioxide water solution to vibrate under ultrasonic
waves and then dried; 2), after the
wool fabric and cationic ceratin
graft polymer powder are mixed, the mixture is treated with a negative pressure-
positive pressure interaction method under high-speed stirring; 3), the wool fabric is subjected to ultrasonic treatment in the wet air environment; 4), the wool fabric is heated and dyed; 5), the dyed wool fabric is treated with a high-pressure treatment-pressure relief treatment
interaction method and then washed and dried. According to the
dyeing method, the wool fabric is subjected to aseries of pretreatment, it is promoted that dye seeps into wool fibers, and thus, the
dyeing degree of the wool fabric is improved. By means of the method, scale
layers of the wool fibers cannot be damaged, and the dyed wool fabric has good anti-felting performance and the capacity of resisting the external physical and chemical effect.
