Binder-Free Non-Woven Hook and Loop Fastener with Island Bonding

The loop component uses a composite structure combining a non-woven loop layer with a woven or non-woven backing layer. The backing layer provides structural support and strength enhancement, while the loop layer maintains engagement functionality. This composite construction allows the loop component to achieve adequate peel and shear strength for limited use cycles while keeping manufacturing costs low through the use of non-woven materials.

The loop component features localized bonding zones where the loop layer is bonded to the backing layer at specific areas rather than uniformly across the entire surface. This local quality approach provides strength enhancement at critical engagement points while leaving other areas unbonded to minimize fiber stress and fuzz formation during engagement and disengagement cycles.

The backing layer serves as a cushioning support structure that prevents excessive compression of the loop fibers during transportation and storage. By providing a rigid or semi-rigid foundation, the backing layer maintains the loop fibers in an upright, engaged-ready position, ensuring that their engagement performance with hook members is not compromised by prior compression.

The loop component is segmented into distinct functional layers: a loop layer for engagement and a backing layer for structural support. This segmentation allows each layer to be optimized for its specific function - the loop layer for fiber engagement and the backing layer for compression resistance and graphic visibility - while maintaining relatively simple manufacturing processes for each individual layer.
