Disposable absorbent product

摘要

The present invention is directed to an absorbent product comprising an elongated absorbent pad having a body facing surface and a garment facing surface, a portion of the garment facing surface being coated with the hot melt adhesive composition comprising: 15 to 40% by weight of a styrene-butadiene-styrene block containing 30 to 50% styrene, the block copolymer having been polymerized so as to have a vinyl content greater than 35%; 30 to 70% by weight of a tackifying resin selected from the group consisting of C5-C10 aliphatic or cycloaliphatic petroleum hydrocarbon resins having a Ball and Ring softening point of 70 DEG to 150 DEG C.; modified hydrogenated rosins; glycerol and pentaerythritol esters of modified hydrogenated rosins; copolymers and terpolymers of natural terpenes; polyterpene resins having a softening point, as determined by ASTM method E28-58T, of from about 80 to 150 DEG C; aromatic petroleum hydrocarbon resins and the hydrogenated derivatives thereof; and copolymers of aliphatic and aromatic monomers; 10 to 30% by weight of naphthenic or paraffinic oil; and 0.1 to 2% by weight of an antioxidant; characterized in that the viscosity of the adhesive is 1000 to 3500 cps at 160 DEG C. In a preferred embodiment, the hot melt adhesive is applied to the pad in a manner such that it serves as both a positioning and construction adhesive.
