Question

The sequence of processes involved in the chemical processing is :
A. scouring
B. finishing
C. dyeing
D. desizing
E. bleaching Choose the correct answer from the options given below:

• A. D, A, E, B, C
• B. D, A, E, С, В
• C. D, A, C, B, E
• D. A, B, C, D, E

Hint:

The "Universal Sequence" for wet processing is always: Preparation $\rightarrow$ Coloration $\rightarrow$ Finishing. Desizing is always the first "wet" step for woven goods.

Answer 1

The Correct Option is B

Concept: The chemical processing of textiles follows a logical sequence aimed at first removing impurities and then adding color and functional properties.

Step 1: Pre-treatment Phase.
The process must begin with D (Desizing) to remove the size paste applied during weaving. This is followed by A (Scouring) to remove natural waxes and oils, and then E (Bleaching) to remove natural pigments and achieve whiteness.

Step 2: Coloration and Final Phase.
Once the fabric is clean and white, it proceeds to C (Dyeing) for color application. The very last stage of any chemical processing route is B (Finishing), where the final hand-feel and functional properties (like softness or water repellency) are imparted.
