[0096] testing method

[0097] opacity method

[0098] Opacity is measured using the following instrument, or equivalent: 0° illumination / 45° detection, circular optical geometry, spectrophotometer with computer interface, such as the HunterLab LabScan XE running Universal Software (available from Hunter Associates Laboratory Inc. ., Reston, VA). Instrument calibration and measurements were performed using standard white and black calibration plates provided by the supplier. All tests were performed in a chamber maintained at 23±2°C and 50±2% relative humidity.

[0099] The spectrophotometer was configured for XYZ color scale, D65 illuminant, 10° standard observer with UV filter set to nominal. The instru...

Abstract

A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article may include a first waist region, a second waist region, a crotch region disposed between the first and second waist regions; a first waist edge and a second waist edge; and a first longitudinal edge and a second longitudinal edge. The disposable absorbent article may include a chassis comprising a topsheet, a backsheet comprising a polymeric film, an absorbent core disposed between the topsheet and the backsheet. The polymeric film may be at least 20 mm more narrow than the chassis. An opacity strengthening patch may be disposed on the backsheet.

Description

technical field [0001] The present invention relates to absorbent articles, such as diapers, which have a narrow polymer film combined with an opacity enhancing patch. The absorbent articles may have improved functional properties and good information transfer properties. Background technique [0002] Absorbent articles, such as conventional taped diapers, are well known to provide the benefit of receiving and containing urine and / or other body exudates. To effectively contain exudates, the article should provide a snug fit around the waist and legs of the wearer. Absorbent articles are known having a chassis comprising a topsheet, a backsheet and an absorbent core. [0003] The backsheet of an absorbent article may form the outer surface and generally comprises two or more materials laminated together. The outermost layer may comprise a soft, substantially liquid impervious, breathable material, such as a hydrophobic nonwoven, which provides softness and a cloth-like fee...
