You can use Deka L dyes on all natural fabrics including cotton, linen, silk, wool and viscose, although they are not suitable for use on synthetic fabrics. Results from dyeing are dependent on the amount of powder in the dye bath, the fibre content of the fabric, the length of dyeing time and the temperature of the dye bath.
Other factors, such as water softness/hardness will also affect the outcome. To achieve a deep black, a more concentrated dye bath, longer dyeing time and a higher temperature will be required. Please note, insufficient water will cause the dye bath to gel.
Always treat pieces requiring frequent cleaning with the Deka L Fixative. This will help to prevent colours from fading when washing on a gentle washing machine cycle at 30°C. Wash separately for first few washes.
General Dyeing Instructions
- Weigh fabric to be dyed, then wash and rinse to remove sizing, fabric softener etc.
- A 10gm sachet contains enough dye powder to dye 250gm (dry weight) fabric. Dissolve dye powder and 2 table spoons salt in 4-5 litres of boiling water and stir well. For silk and wool, also add 8-10 table spoons of vinegar.
- Dampen fabric, put loosely into the dye bath. Maintain the highest temperature suitable for the fabric (a maximum of 90°C).
- Stir frequently for 15-30 minutes.
- Remove fabric and rinse thoroughly under cold running water until water runs clear.
Using Dyes for Wax Batik
Allow dye bath to cool to 50°C.
There are sensible precautions to be taken when handling dyes and chemicals, particularly as powders:
- Avoid inhaling dusts, they can produce an asthma type reaction. People with known respiratory problems should not handle synthetic dyes, and particularly the fibre reactive dyes, in powder form. A dust mask should be worn when working with the powders or exposed to an aerosol from spraying dye solutions made up in water
- Avoid splashing solutions into the eyes, swallowing the materials or prolonged skin contact. A simple ‘non-contact’ approach (most people use gloves to avoid dyeing themselves) plus normal, good, hygiene is sufficient precautions for the occasional user
- Take care with hot
- Store in clearly labelled containers well away from children, pets and foodstuffs. Treat dye powders and solutions with the same caution as domestic poisons (e.g. strong cleaners, bleaches or medicines)
- Dispose of spent solutions containing residues of the dyes responsibly. Dilute and pour onto waste land or into the sewage system. They have no known effect on the environment when used in the quantities recommended
- Not recommended for children younger than 14 years old
