A novel absorbent structure for use in disposable absorbent articles includes a nonwoven fibrous web comprising at least about 5 wt-% of cellulosic materials, having a local density of greater than about 0.2 g/cm<3>, and a density relaxation of less than about 20 %. A novel process for forming a densified nonwoven web includes forming an open structure comprising at least about 5 wt-% of cellulosic materials; heating at least a portion of the open structure to a temperature of at least about 40 ° C; compressing the heated open structure to form the densified nonwoven web to a local density of greater than about 0.2 g/cm<3>; and releasing the densified nonwoven web from compression. |
