What is Tie Dye?
The material to be dyed is first folded into a pattern, and tied or bound with string or rubber bands. Dye is then applied in such a way that it reaches only part of the area to which it is applied. The ties resist the penetration of dye, making tie-dyeing a form of resist dyeing. Designs are also formed by applying different colors of dyes to different sections of the fabric. When reactive dyes are used, the folded and tied textile is usually treated with soda ash solution before dyeing, to prepare it to take the dyes, which may be applied while the fabric is still wet with this solution, or once it has dried. Soda ash, which has a high pH, prepares the cellulose fibers of the cloth for permanent chemical bonding with the fiber-reactive dye used in tie-dyeing. Alternatively, the soda ash may be added directly to the dye solution rather than used as a pre-treatment. With this technique the dye must be used within one or two hours, as the dye will react with the soda ash. After sufficie
