Absorbent belted-article with improved friction between the absorbent pad and the belt

摘要

An absorbent article includes an absorbent pad and a belt to which the pad is detachably attached and which is intended to be attached to a separate belt that is placed around the waist of the wearer to hold the pad when the article is being worn, wherein the absorbent pad exhibits a chassis including a liquid-permeable top sheet and a liquid-impermeable back sheet oriented away from the wearer and an absorbent core between the top sheet and the back sheet. The difference in kinetic coefficients of friction measured with ASTM D 1894-08 standard between the back sheet of the pad and the outwardly oriented surface of the belt is at maximum 0.5. The attachment between the belt and the pad will then not cease due to the movement of the article relative to the surroundings when the belted-article is being used, thereby preventing contamination and leakage caused by detachment.

1. An absorbent belted-article comprising an absorbent pad and a separate belt to which the absorbent pad is detachably attached and which is to be placed around the waist of a wearer to hold the absorbent pad when the belted-article is being worn, wherein the absorbent pad includes a chassis which comprises a liquid-permeable top sheet and a liquid-impermeable back sheet oriented away from the wearer and an absorbent core between the top sheet and the back sheet, and wherein the absorbent pad is detachably attached to the belt by an attaching arrangement, wherein the difference in kinetic coefficients of friction between the back sheet of the absorbent pad and an outwardly oriented surface of the belt is 0.5 at maximum, wherein the kinetic coefficient of friction of the back sheet of the absorbent pad and a surrounding material and the kinetic coefficient of friction of the outwardly oriented surface of the belt and said surrounding material, respectively, are measured with ASTM D 1894-08 standard, and the back sheet of the absorbent pad and the outwardly oriented surface of the belt are formed of different type of materials.
