Abstract

There is provided and absorbent system for personal care products wherein absorbent material is located within an extendible layer. There may be a second outer layer on a side opposite the extendible layer. At least one of the outer layers must be liquid permeable. The layers may be bonded together with a pattern. The absorbent system may be made from a single layer or multiple layers, like, for example, neck-bonded laminates, neck-stretch bonded laminates, stretch-bonded laminates and zero stretch-strain laminates. An additional layer to promote liquid wicking may be located within the structure as well. The absorbent system is useful in personal care products like diapers, training pants, incontinence garments and feminine hygiene products.
