Editor, Nonwovens Industry

A disposable absorbent article was recently patented. It features a topsheet, a backsheet combined with the topsheet and a fluid storage layer between the two. The article has a body-facing surface and a garment-facing surface opposing the body-facing surface. The fluid storage layer contains a superabsorbent material. An odor reduction layer is included at either the body-facing surface side or the garment-facing surface side of the fluid storage layer. The odor reduction layer contains a metalphthalocyanine material. An isolation means is located between the superabsorbent material and the odor reduction layer for isolating the metalphthalocyanine material from contacting at least a part of the superabsorbent material. The odor reduction layer also has a binding agent that is selected from the group consisting of carboxy methyl cellulose, polyurethane, polyfix, polyamine and a mixture thereof.
