Description

Technical Field

[0001] This invention relates to the field of disposable hygiene products technology, and in particular to a diaper that prevents diaper rash from horse oil. Background Technology

[0002] A baby's skin is delicate. When a baby wears a diaper, if diapers are not changed promptly after urination and / or defecation, bacteria can grow in the excrement, irritating the baby's buttocks and even causing contact allergies and diaper rash. Currently, some diapers add skin-care substances, such as the tea polyphenol diaper disclosed in Chinese patent application publication number CN109966056A. In this diaper, the core contains tea polyphenols, which are sprayed onto the upper surface of the core and the upper and lower surfaces of the absorbent layer and penetrate into it. However, this method results in a slow diffusion and release of the tea polyphenols to the diaper surface, leading to less than ideal effectiveness. Summary of the Invention

[0003] Therefore, in response to the above problems, this invention proposes a diaper with horse oil to prevent diaper rash. It can rupture upon contact with urine and quickly release horse oil onto the skin-friendly non-woven fabric surface, thus providing a skin-care effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A type of anti-diaper rash diaper made of horse oil includes, from bottom to top, a leak-proof bottom film, an absorbent core layer, an oleophobic and hydrophilic diversion layer, and a skin-friendly non-woven fabric surface layer.

[0006] The oleophobic and hydrophilic guiding layer is made of non-woven fabric that has been impregnated with a hydrophilic and oleophobic finishing agent and then dried.

[0007] Horse oil microcapsules are evenly distributed on the oleophobic and hydrophilic guiding layer corresponding to the crotch area of ​​the human body. The horse oil microcapsules are located between the oleophobic and hydrophilic guiding layer and the skin-friendly non-woven fabric surface layer.

[0008] The core material of the horse oil microcapsules is made by double emulsification of horse oil and vitamin E at a mass ratio of 10:1 (W / O / W). The core material is then uniformly dispersed in a solution containing a wall material, and a 2% (w / w) calcium chloride solution is added dropwise. The mixture is stirred at 300 rpm for 45 minutes in a curing bath to obtain horse oil microcapsules with a particle size of 40 μm-60 μm. The wall material is a mixture of sodium alginate, chitosan, and gelatin at a mass ratio of 3:2:1.

[0009] Furthermore, the W / O / W dual emulsification is as follows:

[0010] Primary emulsification: The core material is stirred at 10,000 rpm for 3 minutes at 85°C.

[0011] Secondary emulsification: The core material is stirred at 8000 rpm for 2 minutes at room temperature of 20℃-25℃.

[0012] Furthermore, the density of the horse oil microcapsules disposed on the oleophobic and hydrophilic guiding layer is 50,000 capsules / cm³. 2 -100,000 particles / cm 2 .

[0013] Furthermore, the wall material thickness of the horse oil microcapsules is 1μm-5μm.

[0014] Furthermore, the oleophobic and hydrophilic guiding layer is provided with spaced-apart guiding holes, the pore diameter of which is 80±10μm and the density of which is 40 holes / cm². 2 -50 pieces / cm 2 .

[0015] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0016] When this anti-diaper rash horse oil diaper is used, after receiving urine, approximately 78% ± 5% of the horse oil microcapsules soften, dissolve, and rupture within the first 30 seconds, releasing the horse oil, as the pH value of infant urine is generally between 5.5 and 7. Furthermore, due to the oleophobic and hydrophilic properties of the diffusing layer, the horse oil is effectively prevented from seeping downwards into the absorbent core and being absorbed and locked there. Instead, it diffuses to the skin-friendly non-woven fabric surface, coming into contact with the skin and providing a skin-care effect, resulting in excellent performance.

[0017] In addition, adding vitamin E to the core material can effectively reduce the oxidation rate of horse oil. Attached Figure Description

[0021] 1. Leak-proof bottom membrane; 2. Absorbent core layer; 3. Oleophobic and hydrophilic drainage layer; 4. Skin-friendly non-woven fabric surface layer; 300. Human crotch area. Detailed Implementation

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] refer to Figure 1 and Figure 2This embodiment provides a diaper for preventing diaper rash, comprising, from bottom to top, a leak-proof bottom film 1, an absorbent core layer 2, an oleophobic and hydrophilic diversion layer 3, and a skin-friendly non-woven fabric surface layer 4.

[0025] The skin-friendly non-woven fabric surface layer 4 is made of non-woven fabric. The leak-proof bottom film 1 and the absorbent core layer 2 are both existing materials, and will not be described in detail here.

[0026] The oleophobic and hydrophilic guiding layer 3 is made by impregnating non-woven fabric with a hydrophilic and oleophobic finishing agent and then drying it.

[0027] Horse oil microcapsules (not marked in the figure) are evenly distributed on the oleophobic and hydrophilic guiding layer 3 at a position 300 corresponding to the crotch area of ​​the human body. The horse oil microcapsules are located between the oleophobic and hydrophilic guiding layer 3 and the skin-friendly non-woven fabric surface layer 4. The density of the horse oil microcapsules on the oleophobic and hydrophilic guiding layer is 50,000 capsules / cm³. 2 -100,000 particles / cm 2 .

[0028] Specifically:

[0029] The core material of the horse oil microcapsules is made by double emulsification of horse oil and vitamin E at a mass ratio of 10:1 (W / O / W). The core material is then uniformly dispersed in a solution containing a wall material, and a 2% (w / w) calcium chloride solution is added dropwise. The mixture is stirred at 300 rpm for 45 minutes in a curing bath to obtain horse oil microcapsules with a particle size of 40 μm-60 μm. The wall material is a mixture of sodium alginate, chitosan, and gelatin at a mass ratio of 3:2:1.

[0030] Adding vitamin E to the core material can effectively reduce the oxidation rate of horse oil.

[0031] The wall thickness of the horse oil microcapsules is 1μm-5μm.

[0032] The W / O / W dual emulsification is as follows:

[0033] Primary emulsification: The core material is stirred at 10,000 rpm for 3 minutes at 85°C.

[0034] Secondary emulsification: The core material is stirred at 8000 rpm for 2 minutes at room temperature of 20℃-25℃.

[0035] The horse oil microcapsules prepared above were subjected to a simulated 6-month storage process (without external pressure testing) and placed in a high-temperature environment of 45℃±5℃ and a high-humidity environment of 75%±5%RH for 6 months to simulate accelerated aging. The breakage rate after 6 months of storage was approximately 2.1%. The horse oil microcapsules prepared by this method are storable.

[0036] Upon receiving urine, since the pH value of infant urine is generally between 5.5 and 7, approximately 78% ± 5% of the horse oil microcapsules soften, dissolve, and rupture within the first 30 seconds, releasing the horse oil. Due to the oleophobic and hydrophilic properties of the diffusing layer, the horse oil is effectively prevented from seeping downwards into the absorbent core layer 2 and being absorbed and locked there. Instead, it diffuses to the skin-friendly non-woven fabric surface layer 1 and comes into contact with human skin, thus providing a skin-care effect and effectively relieving diaper rash. The results are excellent.

[0037] Example 2

[0038] Based on the above embodiment one, further, flow guiding holes (not shown in the figure) are spaced apart on the oleophobic and hydrophilic flow guiding layer 3. The diameter of the flow guiding holes is 80±10μm, and the density of the flow guiding holes is 40 holes / cm. 2 -50 pieces / cm 2 .

[0039] In this specific embodiment, preferably, the density of the guide holes is set to 45 holes / cm². 2 45 pieces / cm 2 The density of the flow channels can balance the permeation and microcapsule retention rate (98.7%).

[0040] Compared to Example 1, this example shows that by opening a flow guide hole, the urine permeability can be increased by more than 42%.

[0041] By creating drainage holes in the oleophobic and hydrophilic drainage layer 3, urine penetration can be accelerated. Although a small portion of the horse oil microcapsules may enter the absorbent core layer 2 through the drainage holes, this is negligible and will not affect the effectiveness of the horse oil microcapsules on the oleophobic and hydrophilic drainage layer 3.

[0042] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
