Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail. The orientations of up, down, left, right, front and back in the utility model are based on the orientation when using the diaper. the

Referring to Fig. 1 and Fig. 2, a kind of diaper comprises a diaper body, the front end of the diaper body is a front waistline 11, the rear end of the diaper body is a back waistline 12, and the front waistline is provided with a magic front sticker 111 , the back waist is provided with a magic waist button 121, and the main body of the diaper includes a hydrophilic surface layer 13, a flow guide layer, an absorbent core and a breathable bottom film 14 from top to bottom, and the upper surface of the hydrophilic surface layer 13 has a hemispherical shape. The bumps are 130; the hemispherical bumps constitute an inverted trapezoidal cotton hole design, which can effectively reduce the contact area between the hydrophilic surface layer and the skin, and can reduce the contact area by at most 1/4, so that the baby's tender skin can enjoy the most clean Transparent touch, stay away from red ass. The middle part of the absorbent core has two slits 15, the slits 15 are arranged along the length direction of the absorbent core, and the distance between the two slits 15 is 2/3-3/4 of the width of the absorbent core; the two slits The setting makes it easier to bend the left and right sides of the crotch to the center when using diapers, which not only has better comfort and air permeability, but also can effectively prevent O-shaped legs. the

The left and right sides of the hydrophilic surface layer 13 are respectively connected with a water-repellent non-woven fabric layer 16, and the water-repellent non-woven fabric layer 16 is arranged along the length direction of the diaper main body; Also be provided with leak-proof enclosure 17 between, play anti-side leakage effect, the top of described leak-proof enclosure is provided with elastic band 170 along its length direction, described water-repellent non-woven fabric layer 16 and air-permeable base film 14 Adhesive connection, and the absorbent core is not sandwiched between the water-repellent non-woven fabric layer 16 and the breathable bottom film 14; the setting of the water-repellent non-woven fabric layer further plays the role of preventing side leakage, forming a super soft three-dimensional leak-proof diaper The partition side gently protects the baby's tender skin and effectively prevents side leakage of urine. The left and right sides of the air-permeable base film are connected with leg circumference elastics 18, and the leg circumference elastics 18 are located on the outside of the water-repellent non-woven fabric layer. the

The air-permeable base film 14 is made of a composite of non-woven fabric 140 and air-permeable film 141, and the middle part of the composite interface between the non-woven fabric 140 and the air-permeable film 141 is a low-fastness composite area 142, between the non-woven fabric and the air-permeable film The left and right ends of the composite interface are high-fastness composite areas 143, which make the two ends have higher fastness to ensure normal production and prevent the composite materials from disintegrating during use; compared with the composite fastness at both ends, the composite fastness in the middle is lower , which makes the diaper bottom film feel comfortable and soft. the

As an optimization, the middle part of the composite interface between the non-woven fabric 140 and the air-permeable film 141 is a low-fastness composite area 142 that is hot-pressed at a lower temperature, and the composite interface between the non-woven fabric 140 and the air-permeable film 141 The left and right ends are the high-fastness composite zone 143 which adopts higher temperature hot-press composite. When making, the non-woven fabric and the breathable film are extruded and compounded first, and then the heat-pressing method is adopted at a lower temperature to make the diaper bottom film as a whole reach the general compound fastness of the middle part, and finally, the hot spot pressing method is used to separate the diapers. The left and right ends of the composite interface between the non-woven fabric and the breathable film are composited by high temperature hot pressing, so that the two ends of the breathable bottom film can achieve stronger composite fastness, so as to achieve weak fastness in the middle and strong fastness at both ends. Effect. the

As an optimization, the absorbent core includes an upper non-woven fabric layer, a grid layer and a lower non-woven fabric layer from top to bottom, and also includes a polymer material arranged in grids in the grid layer. The macromolecule is arranged in the grid in the grid layer, which plays a good role in fixing the macromolecule, effectively prevents the macromolecule from falling and piles up, and improves the absorption effect of the absorbent core. the
