[0045] (1) Manufacture of surface sheet

[0046] Various surface sheets of the kinds shown in Table 1 were produced. Their KES compression ratios are also shown in Table 1.

[0047] (2) Manufacture of upper absorbent layer

[0048] Various upper absorbent layers of the kind shown in Table 1 were manufactured. Their KES compression ratios are also shown in Table 1.

[0049] (3) Manufacture of anti-compression layer

[0050] Pulp fibers are laminated separately to 200g / m 2 、300g / m 2 、400g / m2 The sheet was cut to a width of 25 mm and a length of 285 mm to obtain a layer resistant to compression. The compression-resistant layers were placed on the lower absorbent body in such a way that their outer side edges overlapped with those of the lower absorbent layer, and the distance between the inner side edges of the compression-resistant layers was 40 mm. The KES compressibility of the anti-compression layer is also shown in Table 1.

Abstract

A disposable diaper comprises an absorber 4 comprising a back absorptive layer 10 containing high absorbing polymer, a pair of anti-compression layer 11 disposed on two sides above said back absorptive layer 10 respectively, and a top absorptive layer 12 primarily containing non-fabric interposed between a pair of anti-compression layer 11, wherein the KES compression rate of said anti-compression layer 11 is not lower than the KES compression rate of said top absorptive layer 12.

Description

technical field [0001] The present invention relates to disposable diapers, and more particularly, to disposable diapers having high absorption and retention properties of loose stools. Background technique [0002] In JP-A-60-198152 and JP-A-62-276003, it is described that a so-called interlayer sheet is arranged between a liquid-permeable top sheet and a liquid-retaining absorbent body to ensure retention of excrement. Disposable diapers for space. However, in these diapers, the interlayer is crushed by the wearer's body pressure during wearing, and the expected holding space cannot be ensured. Also, since disposable diapers are usually sold folded and packaged together in multiples, even in the package, considerable pressure is exerted, thereby also causing the interlayer to be crushed. As a result, it is difficult to sufficiently absorb and retain soft stools as highly fluid excrement, and leakage is likely to occur. [0003] In addition to these publications, there a...
