摘要： An absorber containing non-wood pulp with the settling velocity in water between 2 and 5 seconds, the mean fiber size of 8 to 25 μm, the apparent bulk density of 0.04 to 0.07 g/cm3, and the absorption for 0.9% physiological saline of at least 20-fold with respect to the pulp mass. The absorber has a thickness change of at least 600%, as the thickness after having absorbed 0.9% physiological saline with respect to the thickness before absorbing 0.9% physiological saline. When addition of 80 mL of 0.9% physiological saline to the absorbent article over a period of 10 seconds is performed three times every 10 minutes and the absorption rate of the absorbent article for each of the three times is evaluated as the time from addition of the 0.9% physiological saline until complete absorption, the absorption rate for each of the three times is not greater than 20 seconds.

摘要： A method is provided for recovering pulp fibers having little damage from a used absorbent article that contains pulp fibers and a superabsorbent polymer. The used absorbent article is treated at a temperature of greater than or equal to 80° C. with an organic acid aqueous solution having a pH no greater than 2.5, and the superabsorbent polymer is deactivated. Preferably, the pulp fibers and the deactivated superabsorbent polymer are separated from the used absorbent article after treatment with the organic acid aqueous solution, and further, a mixture including the separated pulp fibers and deactivated superabsorbent polymer is treated with an oxidizing agent, the deactivated superabsorbent polymer is decomposed, reduced in molecular weight and solubilized.

摘要： Provided is a method for efficiently recovering pulp fibers with a high degree of safety and without detriment to the performance of the pulp fibers, from used absorbent articles such as disposable diapers containing pulp fibers and a super absorbent polymer. This method comprises: a step for extracting a mixture of pulp fibers, super absorbent polymer and water from used absorbent articles; a step of using a pair of electrodes to apply a voltage to the mixture of pulp fibers, super absorbent polymer and water to deactivate the super absorbent polymer; and a step for separating pulp fibers from the mixture of pulp fibers, deactivated super polymer and water.

摘要： The problem to be solved by the present invention is to provide an absorbent article in which a reduction in liquid absorbency caused by the hydrophobicity of thermoplastic resin fiber is prevented through the use of thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component. The present invention solves this problem by providing a sanitary napkin provided with a top sheet, a back sheet, and an absorbent body disposed between the top sheet and the back sheet. The absorbent body has an absorbent material layer that contains a cellulose-based hydrophilic fiber and a thermoplastic resin fiber that includes unsaturated carboxylic acid, unsaturated carboxylic acid anhydride, or a mixture of these as a monomer component in a mass ratio of 90:10 to 50:50. The top sheet has an integrated section that is heat-treated together with the absorbent material layer so as to be integrated with the absorbent material layer.
