Dyeing and Dyeing Technology

2016
Dyeing is described as the creating of a new and permanent color, by impregnation of especially a dye onto any material namely, textiles, paper or leather. Cochineal, madder, alkanna, henna, brazilwood, red sandalwood, safflower, indigo and logwood were used for the dyeings which can be carried out directly or after mordanting. The goal of dyeing is to
