Which fabric uses warp-faced twill weave?

• A. Houndstooth Suiting
• B. Surah
• C. Serge
• D. Denim

Answer: (D)

Warp-faced twill means the lengthwise yarns (the warp) dominate the fabric surface, creating a diagonal twill line where the warp threads are most visible. Denim is the classic example of this: it uses a twill weave with indigo-dyed warp yarns that run along the length and a lighter weft, so the surface shows deep blue with the characteristic diagonal pattern. The warp-dominant surface is what gives denim its distinctive look and strength, since the color and texture come mainly from the warp threads.

The other fabrics don’t showcase this warp-dominant diagonal look in the same way. Houndstooth is a patterned fabric that can be produced with twill or plain weave and relies on color contrasts rather than warp dominance. Surah is a plain-weave fabric without the diagonal twill effect, and serge is a twill fabric but not typically identified by the same warp-faced characteristic as denim.
