You can use Deka
L dyes on all natural fabrics including cotton,
linen, silk, wool and viscose. They are not suitable for use
on synthetic fabrics. Results from dyeing are dependent on
the amount of powder in the dyebath, the fibre content of
the fabric, the length of dyeing time and the temperature
of the dyebath. Other factors, such as water softness/hardness
will also affect the outcome. To achieve a deep black, a more
concentrated dyebath, longer dyeing time and a higher temperature
will be required. Please note, insufficient water will cause
the dyebath 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 tbl spoons
salt in 4-5 litres of boiling water and stir well. For silk
and wool, also add 8-10 tbl spoons of vinegar.
- Dampen fabric, put loosely into the dyebath. 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 dyebath to cool to 50°C.
Safety
It is clear that 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 labeled containers well away from children,
pets and foodstuffs. Treat dye powders and solutions with
the same caution as domestic poisons (eg 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
