1. Know what the best types of materials are for dyeing and how to prepare them for dyeing.
The best types of material contain at least 80% cellulose. This includes:
- Cotton
- Rayon
- Linen
- Tencel (Lyocell)
Before tie-dyeing, the material should be washed to remove any sizing (a substance found on new clothing), and then soaked in a bath of soda ash.
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.
3. Know the purpose of the Urea that is mixed with the Dye.
Urea helps to dissolve the dye.
4. What safety equipment should be worn when mixing up the dye for Tie-Dyeing? Why?
At a minimum, an apron and gloves should be worn. Soda ash is somewhat caustic, so you do not want to get it on your skin or on your clothing. You should be aware that dye will color your skin and clothing as easily as it colors a tee-shirt.
5. Determine what the three primary colors are.
The three primary colors for dyes are red, blue, and yellow.
6. Verbally describe what primary colors of dye will be needed to make the following secondary colors. Orange, Green, & Purple.
Orange, green, and purple are called the secondary colors because they are made by mixing two primary colors.
| To make | Mix this | and this | ||
|---|---|---|---|---|
| Orange | = | Yellow | + | Red |
| Green | = | Blue | + | Yellow |
| Purple | = | Red | + | Blue |
7. Verbally describe what the outcome will be if two secondary colors are mixed.
Mixing two secondary colors will produce a shade of brown. This is the same as mixing all three primaries (though it will not be an equal mix of the primaries).
8. Use a Kleenex tissue & colored marker to demonstrate two different types of folds one could do on a T-shirt.
9. Once you have seen the outcome of the different folds you have created on tissue, fold & dye an item for yourself. Bandana, t-shirt, pillowcase, etc… Always keep in mind, no two items will be identical, nor will they be perfect. Each item will be as unique as the individual who made it.
10. Wear or bring this item to the next meeting for your club members to see.
If you are doing this on your own instead of as a club, make sure you clear this with your counselor or director ahead of time. Many clubs award "merit points" for wearing the proper uniform to a club meeting, and you do not want to lose points because you didn't think ahead!
Why not combine this honor with Silk Screen Printing as a creative way for your club to make new field uniforms?
