A method of forming an apertured hydro-patterned nonwoven web including the steps of forming a nonwoven batt comprising continuous spunmelt fibers, calender bonding the nonwoven batt to form a fully bonded precursor nonwoven web with a regular bond pattern that defines individual bond impressions and unbonded areas between the individual bond impressions, the regular bond pattern having a percentage bond area of 10% to 25%, and hydraulically imparting the fully bonded precursor nonwoven web with a plurality of apertures, the step of hydraulically imparting comprising hydraulically treating the fully bonded precursor nonwoven web by a plurality of steps of water injection as the fully bonded nonwoven web passes over a plurality of pins.
