Question

Write the sequence of mechanism of Textile Dyeing.
A. Dissolution of dye molecules in water
B. Absorption of dye into the fiber
C. Dispersion of the dye in the bath
D. Diffusion of dye inside the fiber
Choose the correct answer from the options given below:

• A. A, B, C, D
• B. A, C, B, D
• C. B, A, D, C
• D. C, A, B, D

Hint:

Mechanism of dyeing: Dissolution → Dispersion → Absorption → Diffusion.

Answer 1

The Correct Option is B

Step 1: Dissolution.
Dye molecules must dissolve in water for dyeing to occur (A).
Step 2: Dispersion.
Dissolved dye molecules are then uniformly dispersed in the dye bath (C).
Step 3: Absorption.
The fiber surface absorbs the dye molecules from the bath (B).
Step 4: Diffusion.
Dye molecules then diffuse into the fiber, providing permanent color (D).
Step 5: Conclusion.
The correct sequence: A → C → B → D.
