A body-contacting surface or topsheet for absorbent articles or devices that is comfortable when it is placed in contact with hydrous body tissues is disclosed. In one non-limiting embodiment, the topsheet is a non-absorbent, moderately hydrophilic to substantially hydrophobic nonwoven web. The topsheet can have a critical surface tension of less than or equal to about 45 dynes/cm. In one embodiment, the nonwoven web has been mechanically modified so that it is extensible in an amount greater than equal to about 30% under a force of 50 grams, and undergoes a caliper change of greater than or equal to about 30% under a pressure of 1,000 Pa after being subjected to a pressure of 250 Pa. The topsheet is placed on absorbent devices such as sanitary napkins, tampons, pantiliners, interlabial devices, incontinence devices, bandages, and other types of articles. A method of capturing discharges from a source of discharges on a wearer's body in which at least a portion of the source of discharges is located within hydrous membranes having irregular surfaces (e.g., a female wearer's interlabial or intervaginal space) is also disclosed.
A body tissue-contacting topsheet for an absorbent article that is to be placed in contact with a wearer's hydrous body tissues, said topsheet comprising a non-absorbent, moderately hydrophilic to substantially hydrophobic material having an extensibility in at least one direction of greater than or equal to about 30% under a force of 50 grams, said topsheet having a critical surface tension of less than or equal to about 45, and said topsheet undergoing a caliper change of greater than or equal to about 30% when tested according to the Thickness Change Test.
