Title:
ABSORBENT ARTICLE COMPRISING AN INTERMEDIATE LAYER
Document Type and Number:
WIPO Patent Application WO/2022/252116
Kind Code:
A1
Abstract:
The present invention relates to an absorbent article comprising a topsheet, a backsheet, and a layer of absorbent material disposed between the topsheet and the backsheet wherein the layer of absorbent material comprises superabsorbent polymer, and an intermediate layer comprising a nonwoven web, the intermediate layer being disposed between the layer of absorbent material and the backsheet, wherein the intermediate layer has a MD tensile/basis weight no greater than about 0.75 N/5cm/g/m 2 as measured according to Tensile Strength Test, and a thickness/basis weight no less than about 0.078mm/g/m 2, as measured FTT Test; a nonwoven comprising a MD tensile/basis weight no greater than about 0.75 N/5cm/g/m 2 as measured according to Tensile Strength Test, and a thickness/basis weight no less than about 0.078mm/g/m 2, as measured FTT Test; and a process for producing nonwoven comprising supplying a nonwoven web comprising first thermoplastic fibers having a first melting temperature and second thermoplastic fibers having a second melting temperature, wherein the second melting temperature is at least about 40℃higher than the first melting temperature and, applying heat to the nonwoven web so that at least part of the first thermoplastic fibers are heat-fused one another, wherein the heat has a temperature between the first melting temperature and lower than the second melting temperature.
