Example two
As shown in fig. 1 to 6, in the present invention, according to the high-absorption diaper according to the first embodiment, the diaper main body 100 further includes a second coupling portion 25 located at the front end of the main body portion 21 and a third coupling portion 26 located above the front channel 232, and the second coupling portion 25 is disposed opposite to the third coupling portion 26.
In the invention, the diaper body 100 further comprises a front waist attachment 4 arranged at the upper end of the diaper body 100, a rear waist attachment 5 arranged at the rear end of the diaper body 100, a string 6 and a pulling part 7 arranged on the front waist attachment 4 and connected with the string 6, wherein the string 6 extends between the second coupling part 25 and the third coupling part 26, and the front end of the absorption layer 2 is compressed when the string 6 is pulled; the pulling member 7 includes a first pulling piece 71 and a second pulling piece 72 respectively provided on both sides of the front waist portion 4. The pulling part 7 is arranged on the front waist part 4 in a sticking way.
By providing the pulling member 7, the string 6 is connected to the pulling member 7, and the string 6 extends between the second coupling portion 25 and the third coupling portion 26, and can be manually pushed against the front end of the diaper body 100. The working principle is as follows: when too much urine is absorbed by the front end of the absorption layer 2, the front end of the absorption layer 2 is saturated, the speed of urine flowing to the rear end of the absorption layer 2 is slowed down, and the first pulling block 71 and the second pulling block 72 are pulled manually to compress the front end of the absorption layer 2, so that the urine continues to flow to the rear end of the absorption layer 2. The paper diaper provided by the invention adopts a manual mode to extrude the absorption layer 2 so as to improve the utilization rate of the rear end of the absorption layer 2, and if outgoing personnel do not have a plurality of spare paper diapers, the use time of the paper diaper can be prolonged by using the paper diaper provided by the invention.
In the invention, the skin-friendly layer 1 is woven by non-woven fabrics. The breathable water-proof layer 3 is formed by compounding a breathable film and non-woven fabrics, so that the breathable water-proof layer has the characteristics of breathability and impermeability, moisture can be discharged, and the breathable film is made of polyethylene. The main body 21 is made of a mixture of a super absorbent resin, hydrophilic fibers and fluff pulp.
In the present invention, the main body portion 21 includes a first mixed layer 211, a second mixed layer 212, and a third mixed layer 213 laminated to each other, and a plurality of liquid permeation holes 214 for permeation of liquid are formed in the first mixed layer 211 and the second mixed layer 212. The provision of the liquid-permeable hole 214 can increase the utilization rate of the main body portion 21 and can effectively avoid the problem that the first mixed layer 211 absorbs too much and the second mixed layer 212 and the third mixed layer 21 absorb too little. When urine penetrates into the skin-friendly layer 1 and enters the absorption layer 2 to be absorbed by the first mixing layer 211, part of the urine can rapidly infiltrate down the second mixing layer 212 and the third mixing layer 213 from the liquid-permeable holes 214 and be absorbed, so that the rate of urine continuing to infiltrate down after the first mixing layer 211 is saturated is prevented from being slowed, and absorption of the second mixing layer 212 and the third mixing layer 213 is prevented from being affected. Meanwhile, moisture generated in the process of absorbing urine by the absorption layer 2 is discharged from the air-permeable water-proof layer 3, and the incompletely absorbed urine can be prevented from being permeated to the absorption layer 2 due to the characteristics of air permeability and water impermeability of the air-permeable water-proof layer 3. In this case, the super absorbent resin of the main body 21 can continuously absorb the liquid that has run back.
The diameter of the liquid permeating hole 214 on the upper surface of the first mixing layer 211 is 0.4 +/-0.05 mm, the diameter of the liquid permeating hole 214 is gradually enlarged from the upper surface of the first mixing layer 211 to the lower surface of the second mixing layer 212 to form a trapezoid, and the included angle between the side edge of the liquid permeating hole 214 and the lower bottom edge is 60 +/-3 degrees, so that urine can rapidly permeate from the liquid permeating hole 214 of the first mixing layer 211 to the second mixing layer 212 and the third mixing layer 213. The plurality of weep holes 214 are spaced 3-4mm apart so that the main body 21 can uniformly absorb urine.
In the present invention, the first mixed layer 211 includes 25% ± 3% of super absorbent resin, 5% of hydrophilic fiber and 70% ± 3% of fluff pulp; the second mixed layer 212 comprises 35% +/-3% of high water-absorbent resin, 5% of hydrophilic fiber and 60% +/-3% of fluff pulp; the third mixed layer 213 comprises 90% ± 3% of high water absorption resin, 5% of hydrophilic fiber and 5% ± 3% of fluff pulp, so that the liquid absorption amount of the first mixed layer 211 is the smallest, the liquid absorption amount of the second mixed layer 212 is slightly larger than that of the first mixed layer 211, and the liquid absorption amount of the third mixed layer 213 is the largest; meanwhile, the number of the fluff pulp arranged in the first mixing layer 211 is the largest, and the fluff pulp can rapidly guide urine to the second mixing layer 212 and then to the third mixing layer 213, so that the flow of the urine is accelerated.
The surface of the hydrophilic fiber is coated with a surfactant, and the surfactant can be one or two of sugar alkyl ether and sugar fatty acid ester.
The paper diaper disclosed by the invention adopts the principle of forward osmosis and reverse absorption, the utilization rate of the paper diaper can be improved to the maximum extent, leakage detection of the paper diaper is prevented and the paper diaper is kept dry while the liquid is absorbed quickly, and further, bacterial infection caused in humid environment can be avoided.
