Abstract
An absorbent elastic nonwoven composite material having stretch properties in a machine direction includes an elastic filament matrix and, contained with the matrix, absorbent fibers and a superabsorbent material. A plurality of bond lines oriented in a direction transverse to the machine direction provides reinforcement of the elastic filament matrix so that, when the composite material is stretched, there is less tearing and separation of the elastic filaments. The reinforcement by the bonding lines reduces the separation and shake-out of the absorbent and superabsorbent materials from the matrix during stretching and recovery of the composite material, and improves the recovery. The absorbent elastic nonwoven composite material is useful in a wide variety of personal care absorbent articles and medical absorbent articles.
