摘要:
The present invention provides a pattern-unbonded material that has at least two distinct regions. One region has different bond pattern than another region. The different bond pattern provides different, specific functionality or characteristics to the material. In an embodiment, the one region provides an optimal mechanical fastener, hook engagement. The different characteristics include, but are not limited to, opacity, tensile strength or stiffness. The different characteristics are provided by a bond pattern specific to the particular region. The outer regions, in an embodiment, are stronger and appear more substantial by being more opaque than or color-shifted relative to an inner region. The outer regions, in an embodiment, are not directly backed or supported by the garment to which the material is attached. Accordingly, it is important for the outer regions to provide adequate strength, stiffness, color, and opacity absent the garment backing the outer regions.
