摘要:
The invention includes a hot melt adhesive composition including an olefin polymer and a high melt point hydrocarbon tackifying agent, such compositions unexpectedly provide improved bonding between the layers found in a disposable absorbent article. In particular, such compositions improve the bond between the nonwoven top sheet and the acquisition distribution layer.

Absorbent article (20) comprising a three-dimensional material (200) on the wearer-facing side and an absorbent core with material-free channels (26). The three-dimensional material comprises a fibrous support layer (210), a fibrous projection layer (220) and a plurality of hollow projections (230) formed from a first plurality of fibers in the projection layer.
摘要:
An absorbent article (1) includes a top sheet (10), a back sheet (20), an absorber (30), and a pair of side sheets (41) that cover the widthwise outer ends of the absorber. The widthwise inner ends (41A) of the side sheets are arranged between the absorber and the top sheet in the thickness direction. The pair of side sheets extends more outward in the widthwise direction than the top sheet and the absorber. The density of the side sheets is higher than the density of the top sheet.
摘要:
An absorbent core (28) suitable for use in an absorbent article comprising: -a first absorbent layer (1), the first absorbent layer comprising a first substrate (2), and a layer of cross-linked cellulose fibers (3) deposited on said first substrate, -a second absorbent layer (5), the second absorbent layer comprising a second substrate (6), a layer of superabsorbent polymer particles (7) deposited on said second substrate and a fibrous layer of thermoplastic adhesive material (4) covering the layer of superabsorbent polymer particles (7). The first and second absorbent layers (1, 5) being combined together such that at least a portion of said fibrous layer of thermoplastic adhesive material (4) contacts at least a portion of the layer of cross-linked cellulose fibers (3) of said first absorbent layer (6).
摘要:
The present invention is directed to a novel process for preparing an absorbent article, wherein the process comprises providing a first sheet layer (2); conforming said first layer on a first roll C2, whereby longitudinal corrugations are formed on the layer; conforming said corrugated layer (2) on a second roll C3, whereby a pattern of pockets (4, 4a) is obtained; providing a pre-metered amount of SAP particulate material (6) into said pockets; providing a second sheet layer (7) material and affixing it for sandwiching with the first sheet layer; and finishing the absorbent article.
摘要:
The present invention is directed to a liquid-absorbing article comprising: • - a first sheet layer (2) presenting an array of absorbent receiving pockets (4); • - masses of superabsorbent material (6), which masses are placed in said absorbent receiving pockets; • - a second sheet layer (7) placed on top of the first layer; • - bonding beads (5), ensuring structural strength, placed between the respective pockets. The first sheet layer (2) forming pleats (10) on the masses (6) of superabsorbent material, the pleats being present in a zone that extends about the periphery of the pocket thus formed.
摘要:
The invention relates to disposable diaper having absorbent cores comprising super absorbent polymer particles which are immobilized by adhesive. The absorbent core is attached to the back sheet of the disposable diaper only in certain attachment zones to reduce see-through and the formation of tension lines on the back sheet.
