In Quilted Fabric #107, what bonding method is used?

• A. Stitch Bonding
• B. Ultrasonic Fusion
• C. Needle Punching
• D. Adhesive Lamination

Answer: (B)

Bonding in quilted fabrics is about how the top layer, batting, and backing are held together without relying on visible stitching or wet adhesives. Ultrasonic fusion uses high-frequency vibrations to generate heat at the contact interface, which melts a thin layer of thermoplastic material (or the fibers themselves) and fuses the layers together under pressure. This creates a strong, uniform bond that is typically invisible from the surface and preserves softness and drape, which suits quilted fabrics where a smooth, clean appearance is desired. In Quilted Fabric #107, the look and performance align with this method: a durable bond across the layers without stitching lines or tacky adhesive residue.

Stitch bonding would show visible stitching through the layers, altering texture and appearance. Needle punching interlocks fibers by mechanically punching through them, producing a more textured, lofted surface rather than a crisp bond. Adhesive lamination relies on glue, which can stiffness the fabric and may leave visible film or affect washability. Ultrasonic fusion stands out here because it provides a neat, durable bond that maintains the quilted feel without those trade-offs.
