AY Honors/Tie-Dye/Answer Key
1. Know what the best types of materials are for dyeing and how to prepare them for dyeing.
2. Know what the purpose of the Soda Ash is and how long the fabric is to soak.
Submerging the fabric in a solution of soda ash prepares the fibers of the cloth for permanent chemical bonding with the dye used in tie-dyeing. The folded and tied fabric may be submerged in a bath of soda ash solution for 5-30 minutes. 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. Alternatively, the soda ash may be added directly to the dye solution rather than soaking the fabric in a solution of soda ash. After 12-48 hours, depending temperature, dye, and the desired brightness of the final product, the fabric can be rinsed and unwrapped.
