What is the double knit fabric where the rib wales alternate on the face and back of the fabric called?

• A. Jersey Knit
• B. Interlock Knit
• C. Rib Knit
• D. Purl Knit

Answer: (C)

Rib knit features vertical ribs formed by alternating knit and purl stitches, which create the raised wales that run lengthwise. This structure makes the fabric look like it has alternating ridges on both sides, so turning it over still shows the rib pattern, giving the face and back a similar ribbed appearance. That alternating ribbed texture is the defining trait of rib knit, and it also explains why this fabric stretches well and recovers nicely, making it ideal for cuffs, collars, and waistbands. Jersey knit, interlock, and purl knit have different surface textures and do not present the same distinctive rib structure on both sides, which is why rib knit is the best match for this description.
