Disposable diaper
Abstract
A disposable diaper of generally rectangular outline having longitudinal and transverse directions including a pad of absorbent matter encompassed by a cover sheet comprising a laminated nonwoven fibrous fabric including fibrous web plies having respective longitudinal directions, the web plies being reinforced in their respective longitudinal directions and bonded in superposed relation with their respective longitudinal directions at angle to each other and at angle to the longitudinal direction of the diaper thereby reinforcing the diaper at angles to its longitudinal and transverse directions. The diaper includes wing folds extending longitudinally along the side edges of the diaper to provide a seal around the legs of the child and prevent body exudate from passing outwardly of the diaper in the vicinity of the legs. In one aspect of the inveniton, fibers of the web plies are bonded to the reinforcing medium in a manner such that the fibers are retained in the fabric cover sheet and do not become dislodged to deposit upon the child or other surface even though the diaper becomes wet and is subected to abrasion in the course of normal movements of the child. The desirable absorptivity of the fibrous webs is retained in the product.
