Background
The paper diaper has the advantages of convenient use, comfort, dryness, larger urine absorption amount than that of the traditional diaper, and the like. At present, people are not concerned enough in the market of adult diapers, although the adult diapers are more in brand, the quality of the adult diapers is uneven, the aging process of China is further aggravated, and the market potential of the adult diapers is huge. The basic structures of the adult paper diaper and the infant paper diaper are the same and different, and the adult paper diaper and the infant paper diaper are approximately four-part structures of a surface layer, a flow guide layer, an absorption core layer and a water penetration preventing bottom film from top to bottom. The only difference is that the excretion amount caused by adult incontinence is larger than that of infants, so some manufacturers add a layer of absorbent toilet paper between the bottom film and the absorbent core layer to improve the absorption amount of the diaper, often neglecting the comfort of the diaper.
Because the excretion amount caused by adult urinary incontinence is more than that of infants, the transverse diffusion surface area of the surface layer of the diaper needs to be increased so as to ensure that the absorption core layer can be absorbed more uniformly, and the phenomenon that the local thickening and even the reverse osmosis are caused due to excessive local absorption to block the subsequent absorption of urine is avoided, so that the urine absorption amount is increased; on the other hand, when the adult paper diaper receives a large amount of urine, the contact time between the urine and the skin is reduced, so that the skin contact surface is dry and comfortable, and the comfort of using the paper diaper is ensured.
