Chalk – 12-0304 TCX

Very diluted Pomegranate rind or Myrobalan

Dye: Very diluted Pomegranate rind or Myrobalan

Color: Cream-grey tones, very pale and soft

Color Fastness: Good lightfastness when fixed properly; moderate wash fastness

A. Cotton Dyeing Procedure (Chalk)

Step 1: Mordanting with Alum

  • Material: 100 g cotton
  • Mordant: Alum 8% owf (8 g)
  • Water: 2 L (M:L 1:20)
  • pH: Neutral (~6-7)
  • Temperature: 60°C
  • Time: 45 minutes

Process:

  1. Mordant cotton to prepare fibers for better dye uptake and fixation.

Step 2: Dye Bath Preparation

  • Dye: Pomegranate rind or Myrobalan powder, very diluted (3% owf, 3 g)
  • Water: 2 L
  • pH: Slightly acidic (~5.5-6)
  • Temperature: 80°C
  • Time: 30 minutes (gentle extraction)

Step 3: Dyeing

  • Transfer mordanted cotton to dye bath at 60-65°C
  • Time: 20-30 minutes (shorter due to dilution for pale shade)
  • Stir occasionally for even uptake

Step 4: Rinse & Dry

  • Rinse with cold water gently to avoid removing delicate color
  • Shade dry

B. Silk Dyeing Procedure (Chalk)

Step 1: Alum Mordanting

  • Alum 8% owf
  • 50°C, 40 minutes

Step 2: Dye Bath

  • 3% owf pomegranate rind or myrobalan (very diluted)
  • 80°C, 30 minutes

Step 3: Dyeing

  • 60-65°C, 20 minutes

Step 4: Rinse & Shade Dry

C. Wool Dyeing Procedure (Chalk)

Step 1: Alum Mordanting

  • Alum 7% owf
  • 50°C, 40 minutes

Step 2: Dye Bath

  • 3% owf pomegranate rind or myrobalan
  • 80°C, 30 minutes

Step 3: Dyeing

  • 60-65°C, 25 minutes

Step 4: Rinse & Shade Dry

Explanation & Reasoning:

  • Very dilute dye concentration achieves the pale creamy grey tone of Chalk.
  • Alum mordant increases fiber affinity and color durability without darkening.
  • Slightly acidic pH helps stabilize tannin compounds without damage.
  • Lower dye time prevents deeper color buildup.
  • Rinse gently to preserve delicate dye film.
  • Shade drying prevents sun bleaching of pale colors.
