What is the term for the part of a woven fabric that runs 45 degrees to the selvage and provides the most stretch?

• A. Weft
• B. Warp
• C. Bias
• D. Selvage

Answer: (C)

The main idea here is the direction of grain in woven fabric and how it affects stretch. The term you’re looking for is the bias, which runs at 45 degrees to the selvage. This diagonal grain lets the fabric stretch the most because the warp (lengthwise) and weft (crosswise) yarns aren’t aligned with the fabric’s edges. When you pull along the bias, both sets of yarns contribute to elongation, giving much more stretch than along the straight grain. The warp is the lengthwise direction and is relatively stable with little stretch; the weft runs crosswise and has more give than warp but still less than the bias. The selvage is simply the finished edge of the fabric and doesn’t define a direction of stretch.
