Abstract:
The lab experiment on dyeing of flowers was carried out in Factorial Completely Randomized Design (FCRD) having 22 treatment combinations with 3 replications. The flowers were dyed with 11 different types of dyes viz., Apple Green (D₁), Raspberry Red (D₂), Orange Red (D₃), Violet (D­₄), Dark Green (D₅), Pink (D₆), Brilliant Green (D₇), Crystal Violet (D₈), Methylene Blue (D₉), Rhodamine (D₁₀), Eosin Yellow (D₁₁) dyed with 2 different solutions viz., dye solution in water (T₁) and dye solution with alum as a mordanting agent (T₂). The results revealed that highest score for light fastness property (4.20) was observed in the flowers dyed with indicator dye Brilliant Green (D₇). Food dye Raspberry Red (D₂) got highest points for rubbing fastness property (4.67), however food dye Apple Green (D₁) scored highest points for wash fastness property (4.42). Flowers dyed with dye solutions containing Alum scored highest points for light (3.75) and rubbing fastness properties (3.45). Maximum points for keeping quality (8.01) were scored by flowers dyed with Brilliant Green indicator dye. Flowers dyed with dye solutions containing alum as a mordanting agent scored highest points (7.75) for keeping quality.
