摘要:
The invention clarifies absorption properties of a water-absorbent resin as needed in the case where the ratio by weight of the water-absorbent resin to the total of the water-absorbent resin and the fibrous material is "α," and further the invention provides an absorbent article using a water-absorbent resin which is optimal to the ratio by weight "α" of the water-absorbent resin. A water-absorbent resin, having a concentration absorption index of 35 or more as shown by the following equation (1): A(1-α)+B α
wherein A (g/g) is an absorption capacity of the resin under no load, and B (g/g) is an absorption capacity of the resin under a load, is used as the water-absorbent resin as used for the absorbent article of at least 0.4 in the ratio by weight "α" of the water-absorbent resin to the total of the water-absorbent resin and the fibrous material.
摘要:
The absorbent in accordance with the present invention is limited in at least two of the following requirements: ventilation resistance, absorbency under no load and/or under load, weight mean particle diameter, and water-soluble components. The absorbent exhibits a 24 g/g or more absorbency under a 2.0 kPa load and a 50 kPa·sec/m or less ventilation resistance under a 4.9 kPa load in a wet state. The absorbing product in accordance with the present invention is based on this absorbent and therefore exhibits improved ventilating properties when worn and relatively little wet back of water-based liquids, providing a further improved sense of comfort to users wearing the absorbing product.
摘要:
The present invention provides: a water-absorbing agent which has excellent urine resistance; a water-absorbing agent which has not only excellent urine resistance, but also excellent absorption properties that are stable to any composition of urine and show little change with time; and uses for these water-absorbing agents. The present invention water-absorbing agent exhibits a specific or larger value of absorption capacity under a load in a process in which the absorption capacity under a load is measured in a new manner using a specific liquid to be absorbed, and the present invention provides an absorbent matter which displays a specific or larger value of new absorption index as is, for example, led from the absorption capacity under a load or from the resin concentration using the above water-absorbing agent.
