Different Colors:


Tie & Dye, the Patterns are also formed by applying different color dyes to different sections of the fabric. The folded and tied textile is usually first submerged in a bath of soda ash solution for 5-30 minutes 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 acidic fiber-reactive dye used in tie-dyeing. Dye is then applied, either by submerging the cloth bundle in a bath of dye or by squirting dyes onto specific areas of the fabric.

                                    The soda ash may also be added directly to the dye solution rather than soaking the textile in a solution of soda ash. But with this technique the dye must be used within two hours as the soda ash within the dye solution will react with the dye. In another variation, the fabric may be dyed, and then immersed in soda ash solution.

                 After few hours, according to the level of temperature, dye, and the desired brightness of the final product, the fabric can be unwrapped and rinsed. After working out the excess dye under running water, tie-dye should be washed in a washing machine. A detergent  is preferred by many dyers ,alkaline detergents may cause back staining.

Different dyes:

    There are different kinds of dyes, may be used, most tie-dyers now dye with Procion MX fiber reactive dyes. This class of dyes works at warm room temperatures and the molecules bind with cellulose based fibers (cotton, rayon, hemp, linen) permanently when the pH is raised. Soda ash (sodium carbonate) is generally used to raise the pH and is either added directly to the dye, or in a solution of water in which garments are soaked before dyeing. They do not fade with washing, but sunlight will cause the colors to fade over time.
