There isn't one single "dye formula," as the method for calculating dye amounts depends on the specific application and the type of dye being used. However, a common formula used in textile dyeing is:
Calculating Dye Quantity for Fabric
The provided reference gives a formula for calculating the amount of dye needed:
*Dye = (Shade % Weight of the fabric in gm) / Stock solution % or Required solution = WP / C**
Let's break this down:
- Dye: This represents the amount of dye solution (in grams or milliliters) needed.
- Shade %: This is the desired intensity of the color. A higher percentage means a darker shade. This is determined based on the desired color depth and is often obtained from dye recipes or experimentation.
- Weight of the fabric in gm: This is the weight of the fabric (in grams) you are dyeing.
- Stock solution %: This is the concentration of the dye solution you are using. It represents the percentage of dye in the solution (e.g., a 10% stock solution means 10 grams of dye per 100 grams of solution).
Example:
Let's say you want to dye a 100g piece of fabric to a 50% shade using a 10% dye stock solution.
Dye = (50% * 100 gm) / 10% = 50 gm
You would need 50 grams of the 10% dye stock solution.
Alternative Formula: Required Solution = WP / C
This alternative formula uses slightly different variables:
- Required solution: The amount of dye solution needed.
- W: The weight of the fabric.
- P: The percentage shade desired.
- C: The concentration of the dye solution.
This formula is essentially the same as the first one, just with different variable names.
It's crucial to remember that this formula is a basic guideline. Factors like fabric type, dye type, and desired color fastness can influence the actual amount of dye required. Always refer to the specific dye manufacturer's instructions for optimal results.
