The invention discloses an absorption core with an efficient flow guide property and breathability. The absorption core comprises a surface layer, a bottom layer and an absorption layer. The absorption layer comprises a non-woven fabric layer, the non-woven fabric layer clings to the lower surface of the surface layer, and super absorbent polymers are uniformly scattered in the non-woven fabric layer; the surface layer and the non-woven fabric layer cling to each other to form a compound layer, flow guide grooves are formed in the compound layer, and a core is divided into a plurality of absorption regions by the flow guide grooves; the compound layer is connected with the upper surface of the bottom layer; super absorbent polymers are uniformly scattered between the lower surface of the non-woven fabric layer and the upper surface of the bottom layer. The invention further provides a method for processing the absorption core. The absorption core and the method have the advantages that the plasticizing degree of non-woven fabrics can be lowered to the greatest extent, the softness and the comfort can be enhanced, and the touch can be improved; the SAP (super absorbent polymers) with different properties are arranged among the layers of the absorption core in a matched manner, obvious protrusions are formed after liquid is absorbed by the core, and the absorption core feels soft and comfortable and is good in breathability, high in absorbed liquid diffusion speed and small in skin contact area.

To provide a disposable diaper in which, regardless of the concentration of water absorbent in the absorbent article and the configuration thereof, the liquid return quantity is reduced, and liquid can be captured at an excellent speed. While adjusting the absorption factor and surface tension of the water absorbent to within specific ranges, the water-containing gel-form cross-linked polymer obtained in the polymerization step is crushed to a specific weight-average particle diameter, and after drying has a liquid permeability improver added during or after surface crosslinking, thereby obtaining a water absorbent with excellent GCA (Gel Capillary Absorption) and FGBP (Free Gel Bed Permeability).

The present invention discloses an ink-jet recording sheet which, on at least one surface of a support, has a porous ink absorbing layer containing fine particle silica having the average particle size of 0.5 m or smaller produced by wet process, electrolytes such as alkaline metal salts and alkaline earth metal salts, and polyvinyl alcohol; and then has a gloss layer. The ink-jet recording sheet has excellent features, that is, it has gloss like that of photographic printing paper, the excellent ink absorption speed and ink absorption capacity, and does not produce defects of the coating due to the cracks generated during drying in production processes of the ink absorbing layer. Therefore, the ink-jet recording sheet is suitable as a recording sheet for an ink-jet printer.

The invention relates to an absorption-type article, and the technical problem comprises improvement of the absorption speed of the absorption-type article with a chamber absorber. The technical problems can be solved by the absorption-type article with the absorber 50, wherein the absorber 50 has a plurality of chambers 55 and powder granules containing highly absorbent polymer particles 53; theperiphery of the plurality of chambers 55 are surrounded by joints 54 of upper sheets 51 and lower sheets 52, and the upper sheets 51 and the lower sheets 52 are not jointed. The powder granules are contained in the chambers 55; at least one of the upper sheet 51 and the lower sheet 52 in each chamber 55 forms a concave 50c recessing to the outer side of the chamber 55 in an unfolding state; middle sheets 80 formed by a non-woven fabric are clamped between the upper sheets 51 and the lower sheets 52, the middle sheets 80 are compressed in the thickness direction of the joints 54, and the partlocated in each chamber 55 drums partially up to the corresponding concave part 50c.

The present invention relate to a method for preparing a superabsorbent polymer. The method for preparing a superabsorbent polymer, according to the present invention, allows a superabsorbent polymerhaving an excellent absorption coefficient, absorption rate, and permeability to be provided.
