The excretion of adults is greatly higher than that of infants, so the hydrophilic water absorption performance of the adult paper diaper is far higher than that of the infant paper diaper. The existing adult paper diaper on the market in China has many defects, such as insufficient hydrophilicity, easy leakage, inconvenient wearing and uncomfortable use; the dry and comfortable property is poor, bacterial infection, rash and eczema are easily caused, and for the old, especially for the old lying in bed for a long time, the urine absorbed in the body is easy to seep outwards along the hydrophilic non-woven fabric and the toilet paper due to the existence of the hydrophilic non-woven fabric and the toilet paper, so that the condition of liquid seepage is easy to occur. Adult diaper products in the market are disposable articles and are all integral products, so that the adult diaper is used by the bedridden old people who are more and more concerned about wearing comfort and guarantee better living quality, the whole product is thrown away after the adult diaper is generally used (after the adult diaper is used), the use cost is inevitably increased, and unnecessary waste is caused.
