Meanwhile, FeCO is embedded in the polymethyl methacrylate wall material3Particles, FeCO3Is a solid insoluble in water, and the microcapsule prepared by embedding in the wall material can be stably stored in the absorption core layer without breaking in advance to release the plant essential oil. When the urine is absorbed by the absorption core layer, the urine contains uric acid and is faintly acid, so that FeCO embedded in the wall material of the antibacterial and deodorant microcapsule3The particles can be dissolved under the acidic condition and have a complex reaction with urea in urine to generate a soluble complex, and FeCO in the wall material3The particles are dissolved and react to form a soluble complex, the wall material of the antibacterial and deodorant microcapsule is gradually broken, and the coated plant essential oil is released, so that the paper diaper has the antibacterial and deodorant effect.
Therefore, the antibacterial and deodorant microcapsules are added into the absorption core layer, so that the plant essential oil in the antibacterial and deodorant microcapsules cannot be volatilized and lost in the process of placing the paper diaper, the paper diaper can be stored for a long time, and the microcapsules can be broken to release the plant essential oil only after the antibacterial and deodorant microcapsules are contacted with absorbed urine in the use process of the paper diaper, so that the antibacterial and deodorant effects are achieved, and the cleanness and the health of skin are guaranteed.
Therefore, the invention has the following beneficial effects:
(1) the first elastic cloth belt and the second elastic cloth belt are arranged along the edges of the openings of the left leg and the right leg in a crossed manner, and the magic tapes are arranged at the two ends of the two elastic cloth belts, so that the product can be more attached to the legs by adjusting the attaching positions of the magic tapes and automatically adjusting the tightness of the elastic cloth belts according to the leg circumference of the product, and when the leg areas are tightened, the three-dimensional protection circumference inside the product can be improved, thereby effectively preventing side leakage;
(2) the sticky hook on the hook surface of the magic tape is provided with a plurality of barbs which are uniformly distributed along the circumferential direction of the vertical main body at the top end of the vertical main body, the barbs are bent towards the direction of the base of the hook surface, the convex parts of the barbs face towards the skin when the paper diaper is worn, the sharp top ends face towards the base, when the barbs are pressed, the sharp parts can be pressed towards the base, the skin cannot be stabbed, and the wearing comfort is ensured;
(3) the antibacterial and deodorant microcapsules are added into the absorption core layer, plant essential oil in the antibacterial and deodorant microcapsules cannot be volatilized and lost in the process of placing the paper diaper, the plant essential oil can be stored for a long time, and only when the antibacterial and deodorant microcapsules are in contact with absorbed urine in the using process of the paper diaper, the microcapsules can be broken to release the plant essential oil, so that the antibacterial and deodorant effects are achieved, and the cleanness and the health of skin are guaranteed.

(2) adding lavender essential oil and polymethyl methacrylate into dichloromethane, and uniformly stirring to form an organic phase solution, wherein the mass ratio of the lavender essential oil to the polymethyl methacrylate is 1.2: 1, the mass fraction of the polymethyl methacrylate in the organic phase solution is 1.5 percent;
(3) FeCO is added3Adding the powder into the organic phase solution, stirring and dispersing uniformly to obtain an organic dispersed phase, wherein FeCO is contained in the organic dispersed phase3The mass fraction of the powder is 0.3%;
(4) dropwise adding the organic dispersion phase into a polyvinyl alcohol solution with the mass fraction of 5%, wherein the mass ratio of the organic dispersion phase to the polyvinyl alcohol solution is 0.6: 1, stirring for 35min, heating to 41 ℃, stirring at constant temperature for reaction for 2h, filtering, washing the product with deionized water, and vacuum drying at 50 ℃ for 11h to obtain the antibacterial deodorizing microcapsule.
The rest is the same as in example 1.
The absorbent parts of the diapers in the above examples and comparative examples were soaked in artificial urine (Qingdao Jieshikang Biotechnology Co., Ltd.) having a pH of 4.7 for 1 hour, the fragrance release was measured, and then the bactericidal properties were tested according to the method in GB 15979-. The results are shown in Table 1.
Table 1: and (5) testing the antibacterial and deodorizing performance.
As can be seen from table 1, the antibacterial and deodorant microcapsules prepared by the method of the present invention are added to the absorbent core layers in examples 1 to 3, so that the plant essential oil can be effectively released after urine is absorbed, the fragrance is released to cover the odor of excrement, and the antibacterial effect is generated; in contrast, in comparative example 1, FeCO was not embedded in the wall material of the antibacterial deodorizing microcapsule3The wall materials of the particles and the microcapsules can not be broken after contacting urine and can not release plant essential oil, so that the antibacterial and deodorant effects are obviously reduced; FeCO reduction in comparative example 23The addition of the particles to the extent that they fall outside the scope of the present invention also does not allow for the effective release of the plant essential oil after urine absorption, probably due to FeCO in the microcapsule wall material3Too low embedding amount of particles and FeCO in wall material3The particles do not yet cause effective rupture of the microcapsules after dissolution.
