Description

breathable leak-proof diaper

technical field

The invention relates to a diaper that can not only quickly absorb urine, but also effectively prevent urine leakage under the premise of ensuring a good air-permeable state, and at the same time, greatly improve the comfort of diapers, and greatly reduce the diapers. The utility model relates to a thick breathable leak-proof diaper, which belongs to the field of paper diaper manufacturing.

Background technique

CN104997594A, the name "diapers", comprising a water-impermeable bottom layer, a water-permeable surface layer, and an absorbent core between the two, the absorbent core is wrapped by a coating layer, and the coating layer and the water-permeable surface layer There is a diversion layer between them, and the characteristic is that the diversion layer includes two upper and lower layers of water-absorbing backing paper, and the middle is a mixture of fluff pulp and aromatic salt. Its disadvantages: one is poor air permeability. For babies or children, due to poor air permeability after wearing, the hot urine generated between the urine and the skin can easily cause skin allergies and eczema; After children wear it, they cause friction between the legs, which directly affects the shape development and comfort of the children's legs; third, for adult diapers, due to the large thickness of the absorbent core and poor air permeability, they are not only suitable for wearing.

Contents of the invention

Design purpose: Based on the background technology, to design a diaper that can not only quickly absorb menstrual fluid, but also effectively prevent leakage under the premise of ensuring that the diaper has a good air permeability, and at the same time greatly improve the use of the diaper. Under the premise of comfort, the breathable leak-proof diapers greatly reduce the thickness of the diapers.

Design scheme: In order to achieve the above design purpose. 1. It is one of the technical characteristics of the present invention that the seepage-repellent layer adopts the SMS anti-blood and water-repellent non-woven fabric layer and is located on the back of the liquid-absorbent core. The purpose of this is: since the total osmotic pressure of plasma is 313mOsm, which is equivalent to 7 atmospheres (5330 mm Hg, 1 mm Hg = 0.133 kPa), the rest is crystal osmotic pressure; while SMS non-woven fabrics are resistant to hydrostatic pressure mmH20 >

80>110>130>150>200>220>250>280>300>300>300>300, far less than the total osmotic pressure of plasma, so for the untreated SMS water-repellent non-woven fabric, it can only prevent The passage of water molecules, but cannot effectively prevent the passage of blood plasma, and the anti-hydrostatic pressure mmH20 of the SMS non-woven fabric treated with organic fluorine is far greater than 5330 mm Hg. It can not only effectively prevent the passage of blood components, but also It has good air permeability, will not block the SMS non-woven fabric, will hardly increase the weight of the SMS non-woven fabric, and will not change the feel of the SMS non-woven fabric, so the SMS non-woven fabric treated with organic fluorine can prevent blood plasma The water-repellent and air-permeable properties of the SMS non-woven fabric are ensured. In this application, the SMS blood-repellent and water-repellent non-woven fabric is designed on the back of the liquid-absorbent core layer, which not only achieves the purpose of water resistance and blood leakage, but also realizes To achieve the purpose of water blocking, blood blocking, breathable coexistence. 2. The SMS blood-repellent and water-repellent non-woven fabric layer consists of one layer of SMS blood-repellent and water-repellent non-woven fabric or the superposition of multiple SMS blood-repellent and water-repellent non-woven fabrics, which is the second technical feature of the present invention. The purpose of this design is: although the SMS anti-blood and water-repellent non-woven fabric can prevent the passage of plasma under normal conditions, for users with blood in the stool, the amount of blood loss each time cannot be determined. Anti-blood and water-repellent non-woven fabric prevents it; only when the amount of blood in the stool reaches more than 20ml, there will be a small amount of blood in the stool under the action of the mixed air pressure of the human genitals, and the multi-layer SMS anti-blood and water-repellent non-woven fabric layer The first layer of SMS anti-blood and water-repellent non-woven fabric is blocked by the second layer of SMS anti-blood and water-repellent non-woven fabric. 3, the design of polymer composite SMS non-woven fabric layer is three of technical characterictics of the present invention. The purpose of this design is: because the amount of urine (or the amount of blood in stool) cannot be determined from person to person, for users, they are often in a state of hesitation in choosing diapers with large or small absorption capacity. When using a large amount of diapers, due to the thick absorbent core of the diapers, the traces of the diapers can be clearly seen from the buttocks of the pants after use, which makes the users feel very embarrassed and uncomfortable, especially in spring, summer, Autumn Festival: If you choose diapers with small absorption capacity, although the thickness is thin, no traces of diapers can be seen from the buttocks of the pants after use, but when the amount of urine (or blood in the stool) is large, a small amount of exudation will often contaminate Trousers, especially light-colored trousers, cause unavoidable embarrassment to the user due to the appearance of contaminated urine (or blood in the stool). In this application, a layer of polymer resin is sprayed between two layers of SMS blood-repellent and water-repellent composite non-woven fabrics. Since the thickness of this layer of polymer resin is less than 2mm, the thickness of the diaper is not greatly increased, so that the user can wear it from the pants after use. No traces of diaper use can be seen on the buttocks, and the absorption capacity of diapers is increased by about 50%, which meets the needs of users.

Technical solution: A breathable and leak-proof diaper, comprising a diaper, a diversion layer is placed on the liquid-absorbent core of the diaper, a layer is placed on the diversion layer, and the two sides of the surface layer are three-dimensionally separated from the diaper. There is a layer of anti-seepage layer under the liquid-absorbent core, the outer layer is located under the three-dimensional partition of the diaper and the bottom of the anti-seepage layer, and the anti-seepage layer is spread from the three-dimensional partition of the diaper to both sides of the lower part of the anti-seepage layer.

Compared with the background technology of the present invention, the first is that the SMS anti-blood and water-repellent non-woven fabric is designed on the back of the breathable liquid storage core layer, which not only achieves the purpose of water blocking, but also effectively prevents the leakage of water, realizing water blocking, Under the premise of the coexistence of blood blocking and ventilation, the thickness of the diaper product is greatly reduced; the second is the design of the polymer composite SMS non-woven layer, which not only greatly reduces the thickness of the large absorption capacity diaper, but also ensures The absorption capacity of the pair of diapers with large absorption capacity is improved and improved, so that the user cannot see traces of using the diapers from the buttocks of the trousers after use, which meets the needs of users.
