Abstract
This study explores the dyeing property of extract curcumin (yellow) as a natural plant dyestuff to bamboo pulp fiber through tests. Four dyeing methods, namely direct dyeing, pre-mordant dyeing, post-mordant dyeing, and one-bath dyeing have been conducted respectively to compare the dyeing effects of the different methods so as to select the one with the best dyeing effect. Next, through the method of controlling variables, control different factors (temperature, type of mordant, dosage of mordant, PH value, dyeing time, and the soaking time before dyeing), carry out related dyeing and test the relevant data (dye-uptake, fixation rate, dyeing rate and fastness to washing) on this basis. Finally, through counting, analyzing and discussing the experimental data, turmeric dye has been provide to be the reasonable and efficient dyeing process on bamboo pulp fiber.
