Research on Fast-growing Poplar Dyeing Technology based on Material Properties

摘要

By exploring the acid yellow G to buck dyes dyeing was carried out on the fast-growing Yang path of material. Through orthogonal test to determine the optimum technology of dyeing; Test results are as follows. Dyed with acid dyes, test optimization process is dye mass fraction is 0.3%, dyeing time for 4 days, penetrating agent mass fraction is 0.05%, the dye solution pH value of 5.2.
