The correct answer is
D, A, E, C, B
Chemical Processing Sequence Explained
The correct order for chemical processing in textiles is crucial for achieving the desired fabric quality. The standard sequence ensures each step effectively prepares the fabric for the next.
Standard Textile Chemical Processing Steps
The typical sequence involves the following stages:
- Desizing (D): This is the initial step where sizing agents applied during weaving are removed. This allows subsequent treatments to penetrate the fabric effectively.
- Scouring (A): Following desizing, scouring removes natural impurities (like waxes, oils, pectins) and residual sizing. This step ensures uniform absorbency and cleanliness.
- Bleaching (E): Bleaching is performed after scouring to remove any remaining coloring matter and achieve a uniform white base, especially important for light-colored dyeing or printing.
- Dyeing (C): Once the fabric is cleaned and whitened, it is ready for dyeing to impart the desired color.
- Finishing (B): This is the final stage, involving various treatments (e.g., softening, stiffening, water-repellent coatings) to improve the fabric's appearance, handle, or performance properties.
Therefore, the correct sequence is Desizing -> Scouring -> Bleaching -> Dyeing -> Finishing, which corresponds to D, A, E, C, B.
The correct option is the one matching this sequence.
