Abstract
A loop material for a hook and loop type fastener is a composite nonwoven. The composite nonwoven consists of a loop layer, a backing layer, and a plurality of bond regions. The loop layer may be a carded nonwoven of thermoplastic crimped staple fiber. The staple fiber may be between 1.5 to 6.0 dTEX. The loop layer may have a basis weight of between 10 and 35 g/m. The backing layer may be a spunbond or spunmelt nonwoven having a basis weight of 5 to 30 g/m. The loop layer may be superimposed face-to-face with the backing layer. The plurality of bond regions joins the loop layer to the backing layer and rendering said bond regions substantially air impermeable. The bond regions comprise between 35 to 55% of a surface area of the loop material.
