摘要:
Absorbent structures (100) comprising a thermally-bonded fluid acquisition/distribution layer (10) comprising from about 10 % to about 50 % thermoplastic bonding material and from about 50 % to about 90 % of chemically stiffened cellulosic fibers and, positioned beneath said fluid acquisition/distribution layer, a fluid storage layer (106) comprising at least about 15 % by weight, superabsorbent material. The thermally-bonded fluid acquisition/distribution layer is a web comprising the chemically stiffened cellulosic fibers and thermoplastic bonding material made by blending the stiffened fibers with the thermoplastic bonding material when in a fibrous form, forming the web, heating the web to melt the thermoplastic fibrous material, and cooling the web.
摘要:
An absorbent article such as disposable diaper, training pant, and adult incontinence undergarment comprising superabsorbent polymer particles able to absorb and contain body exudates having improved absorption properties and therefore reduce leakage, especially at the first gush, i.e. when the article starts to be wetted.
摘要:
Absorbent structures having a wetlaid fluid acquisition/distribution layer (110) with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0 % NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm2; and a fluid storage layer (108) positioned beneath the acquisition/distribution layer (110) comprising at least about 15 % superabsorbent material. The fluid acquisition/distribution layer (110) comprises from about 50 % to 100 % chemically stiffened cellulosic fibers and from 0 % to about 50 % binding means.
摘要:
The invention refers to a fibrous sheet material comprising at least two plies (1, 2) that are bonded together, said fibrous sheet material containing a superabsorbent material, in the form of a web (7) of filaments having a diameter in the range between 1 and 40 μm. The web of superabsorbent filaments having a basis weight between 1and 15 g/m 2 and is located between said plies. The invention also refers to a method for applying a superabsorbent polymer to a fibrous sheet material and to produce a superabsorbent double-or multiply fibrous sheet material.

摘要:
Absorbent structures are disclosed comprising a fibrous, superabsorbent core and an integrally attached facing layer. The structures can be made by forming nonwoven webs of mixtures of thermoplastic fibers and superabsorbent fibers, and a web consisting essentially of thermoplastic hydrophobic fibers. The layers are bonded together using thermal bonding. The structures are suitable for use in disposable absorbent products, in particular, pantiliners.

The invention relates to a process for producing water-absorbing crosslinked polymer fibers, especially micro- or nanofibers, by spinning process, especially electrospinning process and to fibers obtainable by this process.
摘要:
An absorbent article having a stretchable substrate and an absorbent composite comprising a layer of adhesive composition in contact with the stretchable substrate. A layer of particulate superabsorbent material is applied to and held by the adhesive composition. The absorbent composite is secured to the substrate by the adhesive composition. The stretchable substrate has a recovery in at least one of the lateral direction and the longitudinal directions of the article as determined by an Elongation and Recovery Test, and the absorbent article has a recovery in the at least one of the lateral direction and the longitudinal direction as determined by the Elongation and Recovery Test that is at least about 60 percent of the recovery of the substrate in the at least one of the lateral direction and the longitudinal direction.
