Fiberfill bonding method in the mechanical-bonded form?

Fiberfill bonding method in the mechanical-bonded form?

• A. Adhesive Bonded
• B. Sewn Bonded
• C. Thermally Welded
• D. Mechanical Bonded

Answer: (D)

Mechanical bonding relies on physically interlocking the fibers to form a cohesive layer. This is typically done by needle-punching or other entangling processes that lock fibers together without using glue or heat. In a fiberfill that’s mechanically bonded, the structure stays lofted and fluffy because the fibers are held in place by the intertwined network, not by adhesive or melting. This is different from adhesive bonded, which uses a binder; sewn bonded, which relies on stitching to hold layers; and thermally welded, which fuses fibers with heat. So the bonding method here is mechanical-bonded because the cohesion comes from actual physical interlocking of fibers.
