Question

Woven fabric has the greatest stretch in the:

• A. Garment bias
• B. True bias
• C. Warp direction
• D. Weft direction

Hint:

Cutting garments (such as cowl necks or bias-cut skirts) on the true bias allows the fabric to stretch and drape smoothly over the contours of the body without requiring a knit structure.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Woven fabrics are composed of two sets of interlacing yarns: warp yarns (running lengthwise) and weft/filler yarns (running crosswise).
The orientation or direction along the fabric determines its structural stability and elasticity.

Step 2: Detailed Explanation:
Let us analyze the stretch characteristics in different directions of a woven fabric:
Warp Direction (C): The lengthwise direction. Because warp yarns must withstand high tension on the loom, they are tightly spun and have minimal stretch.
Weft Direction (D): The crosswise direction. It generally has slightly more stretch than the warp direction, but is still restricted by the interlacing structure.
Bias Directions: Any diagonal direction that cuts across the warp and weft yarns.
True Bias (B): A specific diagonal direction oriented at a precise \(45\text{-degree}\) angle to the warp and weft directions.
At this angle, pulling the fabric does not stretch the individual yarns themselves.
Instead, it pulls against the spaces in the woven grid, causing the rectangular weave structure to distort into diamonds.
This structural shifting gives the woven fabric its maximum natural stretch, flexibility, and fluid drape.

Step 3: Final Answer:
Woven fabric exhibits its greatest natural stretch along the True bias.
