There is a great social demand for diapers for infants, feminine sanitary napkins and diapers for adults. Due to the special uses of these sanitary products, there are high requirements for their air permeability and anti-leakage properties. The bottom film of hygienic diapers commonly used in the market is PE cast film. PE cast film is economical and has good anti-leakage effect, but its air permeability is poor. After long-term use, babies will have red buttocks and even eczema. It is comfortable for adults to use. The sensory experience is also very poor. In order to solve the problems raised in the above-mentioned background technology, Wang Xiaochun proposed a backsheet diaper with strong air permeability.
The technical solution is as follows: a backsheet diaper with strong air permeability includes a diaper body, the diaper body includes a bottom film and an absorbent core installed on the diaper body, one end of the diaper body is symmetrically installed with front wings, and the other side of the diaper body One end is symmetrically installed with rear wings, and the bottom film includes a hydrophilic layer, a water-absorbing layer, a film layer and a water-repellent layer, and the side wall of the hydrophilic layer close to the water-absorbing layer is evenly provided with protrusions one, and the water-absorbing layer is close to the side wall of the hydrophilic layer Protrusions are evenly arranged on the top, the film layer is arranged under the water-absorbing layer, the water-repellent layer is arranged under the film layer, and the bottom film is provided with ventilation holes in an array. Using the above scheme, the bottom film includes a hydrophilic layer, a water-absorbing layer, a film layer and a water-repellent layer. When in use, the hydrophilic layer is conducive to the penetration of urine, and the urine penetrates into the water-absorbing layer and is absorbed by the water-absorbing layer. The film layer and the water-repelling layer The water-repellent layer can prevent urine from penetrating, and the hydrophilic layer is made of non-woven fabric, and there are protrusions between the hydrophilic layer and the water-absorbing layer. The gaps between them increase the air permeability of the bottom film, and there are also arrays of ventilation holes on the bottom film, which further improves the air permeability.
Compared with the prior art, the beneficial effect of this scheme is:
The backsheet diaper improves the air permeability of the main body of the diaper and has a good water absorption effect by setting the structure of the bottom film, the front flank, the rear flank, the hydrophilic layer, the water-absorbing layer, the first protrusion, the second protrusion, and the air holes; Diaper improves the anti-penetration effect of the main body of diapers by setting a film layer and a water-repellent layer, and cooperates with each other. It is easy to use and is worth promoting.
