Using Nano-pigment for Coloration of Leather
Mainly leather is dyed using anionic dyestuffs such as acid, direct and metal complex dyes, but the use ofpigments is not common for leather dyeing. Dye penetration into the inner layers of the leather is a difficult task dueto 3D infrastructure of leather.In the present study, an attempt has been made to improve the exhaustion of nano-pigment in dyeing leather byusing ultrasound. Optimum dyeing conditions including reduced dyeing time is aimed.Taguchi method was employed for the design of experiments. CIELAB color coordinates reflectance values of dyedleathers were evaluated using a reflectance spectrophotometer. The K/S values of the samples were considered to beproportional to the absorption of nano-pigment into the leather. The optimum level of the effective parametersnamely as: wetting time, type of swelling agent, ultrasonic bath time, and amount of pigment were evaluated andconfirmed by complementary experiments.
