Question

Which of the following layout is NOT suitable for unidirectional fabrics ?

• A. Double lengthwise fold
• B. Crosswise fold
• C. Open fold
• D. Longitudinal fold

Hint:

For fabrics with a distinct directional pattern, print, or nap (like velvet or corduroy), never use a crosswise fold. This ensures that half of your garment panels do not end up upside-down.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Unidirectional fabrics have a print, nap, pile, or design that runs in one direction only.
When cutting patterns on such fabrics, all pattern pieces must be laid out in the same direction so the final garment does not have upside-down panels.

Step 2: Detailed Explanation:
Let us analyze the effect of different folding layouts on unidirectional fabrics:
- Lengthwise/Longitudinal Folds: Folding the fabric along its length keeps both layers oriented in the same vertical direction.
Pattern pieces cut on these folds will maintain the correct upward orientation.
- Open Layout (Open Fold): Cutting on a single layer of fabric allows the designer to place each pattern piece facing the same direction.
- Crosswise Fold: In a crosswise fold, the fabric is folded horizontally across its width.
This causes the top layer to run in one direction while the bottom layer runs in the exact opposite direction.
If symmetrical pattern pieces are cut on a crosswise fold, one half of the cut pieces (e.g., one sleeve or the back panel) will end up upside-down.
Therefore, a crosswise fold layout is completely unsuitable for unidirectional fabrics.

Step 3: Final Answer:
The layout that is NOT suitable for cutting unidirectional fabrics is the Crosswise fold.
