Abstract
The invention is a disposable absorbent article for topical adhesive attachment to a wearer. The article has a wearer facing surface and a garment facing surface and comprises an absorbent core. The article comprises an adhesive on at least the wearer facing surface. The adhesive has a dynamic elastic behaviour so that the difference between G′37 at a frequency of 1 rad/sec and G′37 at a frequency of 100 rad/sec is not greater than 150% of G′37 at a frequency of 1 rad/sec. The adhesive has a dynamic viscous behavior so that the difference between G″37 at a frequency of 1 rad/sec and G″37 at a frequency of 100 rad/sec is not greater than 10,000 Pa. The ratio G′37 over G″37 in the frequency range 1-100 rad/s is greater or equal to 3.3.
Claims16
Disposable absorbent article for topical adhesive attachment to a wearer of said article said article having a wearer facing surface and a garment facing surface and comprising an absorbent core between said wearer facing surface and said garment facing surface wherein
- said article comprises on at least part of said wearer facing surface an adhesive for said topical adhesive attachment of said article,
- said adhesive having an elastic modulus at a temperature of 37° C. (100° F.), G′37, and having a viscous modulus at a temperature of 37° C. (100° F.), G″37,
- said adhesive being selected to have a dynamic elastic behaviour such that the difference between G′37 at a frequency of 1 rad/sec and G′37 at a frequency of 100 rad/sec is not greater than 150% of G′37 at a frequency of 1 rad/sec, and,
- said adhesive being selected to have a dynamic viscous behaviour such that the difference between G″37 at a frequency of 1 rad/sec and G″37 at a frequency of 100 rad/sec is not greater than 10000 Pa;
- and,
- wherein the value of the ratio G′37 over G″37 in the frequency range 1-100 rad/s is greater or equal to 3.3.
