Question:

Which of the following finishes makes use of rib weave fabric?

Show Hint

Textile Calendering Finishes:
Moiré $\rightarrow$ Rib weave fabrics (watermark effect).
Schreinering $\rightarrow$ Micro-grooved roller for high silk-like luster.
Crabbing $\rightarrow$ Wool setting.

The Correct Option is A

Solution and Explanation


Step 1: Understanding the Concept:

Mechanical calender finishing processes produce optical watermark luster effects on ribbed textile substrates.

Step 2: Detailed Explanation:

Moiré Finishing (Watered Silk Effect):
- Applied specifically to unbalanced ribbed weave fabrics (such as taffeta, faille, ottoman, or grosgrain).
- When two layers of ribbed fabric are fed slightly askew through heated metal calender rollers under tremendous pressure, the rib yarns of one layer flatten the rib yarns of the other layer at localized cross-over points.
- The resulting irregular flattening alters light reflection, producing a shimmering, wood-grain or wavy watermark (moiré) pattern.

Step 3: Final Answer:

Therefore, Moiré finish makes use of rib weave fabric, matching option (A).
