A. Cotton Dyeing Procedure (Sea Kelp)

Step 1: Mordanting

• Material: 100 g cotton
• Mordant: Ferrous sulfate 5% owf (5 g)
• Water: 2 L (M:L 1:20)
• pH: Neutral (~6)
• Temperature: 55°C
• Time: 45 min

Process:

1. Dissolve 5 g ferrous sulfate in 2 L warm water at 55°C.
2. Add pre-wetted cotton fabric, stir gently for 45 minutes to ensure mordant binds cellulose fibers.
3. Rinse lightly in cool water to remove excess mordant.

Reason: Iron mordant is critical for olive tones; cotton requires mordant uptake before dyeing.

Step 2: Dye Extraction & Dyeing

• Dye: Pomegranate rind powder 15% owf (15 g)
• Water: 2 L
• Temperature: 70°C
• Time: 60 minutes
• pH: Slightly acidic 5.5-6

Process:

1. Boil water and add pomegranate rind powder, simmer for 45 minutes to extract dye.
2. Strain to remove solids.
3. Cool to 65-70°C and add mordanted cotton.
4. Maintain temperature, stir gently for 60 minutes.
5. Remove fabric, rinse in cold water, dry in shade.

Reason: Pomegranate tannins develop well at slightly acidic pH and warm temps; iron mordant interaction produces olive-green hues.

B. Silk Dyeing Procedure (Sea Kelp)

Step 1: Mordanting

• Material: 100 g silk
• Mordant: Ferrous sulfate 5% owf (5 g)
• Water: 2 L (M:L 1:20)
• Temperature: 50°C
• Time: 30 min

Process:

1. Dissolve mordant at 50°C; add silk fabric, gently stir for 30 min.
2. Remove silk, rinse lightly.

Step 2: Dyeing

• Dye: Pomegranate rind 10% owf (10 g)
• Water: 2 L
• Temperature: 60°C
• Time: 45 min

Process:

1. Simmer pomegranate rind for 30 min, strain.
2. Cool dye bath to 60°C, add silk fabric, stir gently for 45 min.
3. Remove, rinse cold, dry in shade.

C. Wool Dyeing Procedure (Sea Kelp)

Step 1: Mordanting

• Water: 2 L
• Temperature: 60°C
• Time: 45 min
• pH: Slightly acidic 5.5

Process:
