摘要：
Disclosed is a preparation method for a dry and comfortable absorbent article, the method comprising the following preparation steps: 1) preparing a liquid-permeable surface layer； 2) preparing an absorbent core: (1) inputting a hydrophilic surface layer material (7) into a pair of press roller assemblies comprising a concave roller (1) and a convex roller (2), and forming array-type accommodating grooves in the hydrophilic surface layer material (7)； (2) adding a water-absorbent resin (6) to each of the accommodating grooves； (3) covering the accommodating grooves of the hydrophilic surface layer material (7) with another non-woven fabric material (8)； (4) performing a thermal press-bonding treatment on the hydrophilic surface layer material (7) and the non-woven fabric material (8) thereon through a pair of press-bonding rollers； (5) performing, by means of an ultrasonic combination device, a sealing treatment on the hydrophilic surface layer material (7) and the non-woven fabric material (8) subjected to the thermal press-bonding treatment； (6) flipping the core 180 degrees after the thermal press-bonding treatment in step (5) has been performed； and (7) cutting the flipped core according to a set length； 3) preparing a liquid-tight bottom layer； and 4) combining the liquid-permeable surface layer, the absorbent core and the liquid-tight bottom layer prepared in the above steps into a whole. The preparation method overcomes the defect in the prior art that a water-absorbent resin is prone to shifting or aggregation.L'invention concerne un procédé de préparation d'un article absorbant sec et confortable, le procédé comprenant les étapes de préparation suivantes : 1) préparation d'une couche de surface perméable aux liquides ； 2) préparation d'une âme absorbante : (1) introduire un matériau de couche de surface hydrophile (7) dans une paire d'ensembles rouleaux presseurs comprenant un rouleau concave (1) et un rouleau convexe (2), et former des rainures de réceptio
