The present invention is a disposable garment for alleviating unpleasant scents and bodily waste when worn by users. Disposable undergarments such as diapers and other similar garments can be a challenge to use when the garment has been soiled. Various applications of specially designed layers of material can be an effective tool when odors and excretion are unbearable. Garments that are manufactured to combat the difficult process of dealing with bodily waste is a benefit to the public; especially when excretion occurs unexpectedly.

Process for making an absorbent article comprising a topsheet/acquisition layer laminate

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
