The utility model patent that current patent publication number is CN203815724U discloses a disposable diaper, including leak protection separate limit, waistline rubber band, protect enclose rafter muscle, surface course, water conservancy diversion layer, leak protection basement membrane and intermediate layer formula complex absorption core, the cladding of intermediate layer formula complex absorption core is between leak protection basement membrane and surface course. In use, the sandwich type composite absorption core body can effectively absorb urine, so that a user can keep dry and comfortable. However, the disposable diaper is usually used by being directly attached to the inner side of the clothes, and the disposable diaper is easy to shift during use, so that the disposable diaper is inconvenient to use.

The paper diaper is also an optional applicable product for infants or incontinent patients, the action principle of the paper diaper is consistent with that of a paper diaper, and only the paper diaper can be directly worn by a user. For example, a prior utility model patent with a patent publication No. CN208770170U discloses an elastic waistline diaper, which comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorber arranged between the two layers; the rear waist region of the diaper is positioned between the liquid-permeable surface layer and the liquid-impermeable bottom layer and is provided with an elastic waistline which is composed of two layers of non-woven fabrics and a plurality of rubber bands arranged between the two non-woven fabrics in a transverse direction in parallel.

When in use, the paper diaper is fixed on a human body through the elastic waistline, thereby ensuring the stability of the paper diaper. Although the problem that the diaper is easy to shift cannot occur, the diaper is fixed through the elastic waistline, and the waistline usually contains about 40 rubber bands, so that the diaper is high in cost, and poor in wearing comfort and breathability. Also, when the user's urine volume is relatively small, the bulky diaper does not need to be used at all. Further, when it is difficult for the user to raise his or her legs due to the inconvenience of his or her legs, the diaper is also very troublesome to wear.
