What is the face and back fiber composition for bonded knit fabric?

• A. 100% polyester on both sides
• B. Face contains wool and polyester; back is cotton
• C. 80% wool/20% polyester on the face; 100% polyester on the back
• D. 50% wool/50% acrylic on the face; back is nylon

Answer: (C)

Bonded knit fabrics are made by fusing a knit face to a supportive backing, so the fiber composition is chosen to balance how the fabric looks and feels on the outside with how it bonds on the inside. The best answer reflects this by using a face that is a wool blend for warmth and desirable hand, paired with a back that is 100% polyester to provide strength and a stable surface for bonding. The wool in the face gives the fabric its natural softness and warmth, while the polyester back supplies dimensional stability and a consistent, strong bonding layer. Other options mix in fibers like cotton, acrylic, or nylon on the back or use all-polyester on both sides, which would alter texture, comfort, or bonding performance in ways that are less typical for bonded knits.
