[0024] The application provides a bacteriostatic and deodorizing diaper. The bacteriostatic and deodorizing diaper is obtained by adding microcapsules 33 with bacteriostatic and deodorizing functions into an absorbent core 30 during online production of the diaper or during offline production of the absorbent core 30. Online production refers to that the absorbent core 30 is produced synchronously during production of the diaper, while offline production refers to that the absorbent core 30 is produced before production of the diaper and then directly combined with the diaper during production of the diaper.
[0025] As shown in the drawings, Figure 1 The bacteriostatic and deodorizing diaper comprises, in sequence, a hydrophilic surface layer 10, a flow guide layer 20, an absorbent core 30, a leakage prevention layer 40, and a bottom layer of non-woven fabric 50. In an embodiment, the layers of the hydrophilic surface layer 10, the flow guide layer 20, the absorbent core 30, the leakage prevention layer 40, and the bottom layer of non-woven fabric 50 are bonded by hot melt adhesive. In use, the hydrophilic surface layer 10 is in contact with the skin of a human body. The flow guide layer 20 is used to guide liquid on the hydrophilic surface layer 10 to the absorbent core 30. The absorbent core 30 is used to absorb feces and urine and to inhibit bacteria and remove odor. The leakage prevention layer 40 is used to prevent leakage of feces and urine.
[0026] The bacteriostatic and deodorizing diaper further comprises a front adhesive member 60 and a rear adhesive member 70. The bacteriostatic and deodorizing diaper has a first end 80 and a second end 90 along a length direction thereof. At least a part of the front adhesive member 60 is arranged on the first end 80, and at least a part of the rear adhesive member 70 is arranged on the second end 90. The front adhesive member 60 is used to be adhered to the rear adhesive member 70. In use, the bacteriostatic and deodorizing diaper is arranged on the lower body of a human being, and the first end 80 and the second end 90 are arranged at the front waist and the rear waist of the human body, respectively. That is, the front adhesive member 60 is arranged at the front waist of the human body, and the rear adhesive member 70 is arranged at the rear waist of the human body. The rear adhesive member 70 is stretched from the rear waist to the front waist to be adhered to the front adhesive member 60. Thus, the diaper can be worn on the human body. Since the rear adhesive member 70 is stretched to the front waist to be adhered to the front adhesive member 60, the diaper can adapt to different waist circumferences of the human body. The tightness of the diaper can be adjusted by changing the position of the rear adhesive member 70 adhered to the front adhesive member 60.
[0027] As shown in the drawings, Figure 2 The absorbent core 30 comprises an upper wrapping non-woven fabric, a lower wrapping non-woven fabric, and a plurality of microcapsules 33. The microcapsules 33 are wrapped in a space enclosed by the upper wrapping non-woven fabric 31 and the lower wrapping non-woven fabric 32. The upper wrapping non-woven fabric 31 and the lower wrapping non-woven fabric 32 can be used to wrap the microcapsules 33. Figures 3-4As shown, the microcapsule 33 is a micro-packaging technology for storing powder bacteriostatic deodorizing substances. The bacteriostatic deodorizing substances are wrapped in the solid particle molecules in the capsule wall 331 as the capsule core 332. In an embodiment, the diameter of the microcapsule 33 is 1-500 microns, and the thickness of the capsule wall 331 is 0.5-150 microns. The capsule particle size is small, and there is no obvious foreign body sensation in actual experience, and it does not affect the absorption capacity of the polymer water-absorbing resin 333 to urine. The microcapsule 33 includes the capsule wall 331 and the capsule core 332, and the capsule wall 331 is wrapped around the periphery of the capsule core 332. The capsule core 332 includes bacteriostatic deodorizing substances, and the bacteriostatic deodorizing substances are plants or plant extracts.
[0028] Preferably, the microcapsule 33 can be a sphere. The use process of the microcapsule 33 is as follows: when the incontinent population wears the diaper, the body excretes urine and feces, and the capsule wall 331 of the microcapsule 33 in the diaper absorption core 30 is stimulated by the human urine or feces, and slowly expands to a certain extent to break, and the substances in the capsule core 332 are slowly released to play a role in bacteriostasis and deodorization. That is, the capsule wall 331 of the microcapsule 33 will swell and dissolve under certain conditions to release the capsule core 332. The specific conditions can be that the capsule wall 331 will swell and dissolve at a temperature greater than a certain temperature, or the capsule wall 331 will swell and dissolve between a certain pH, etc. The specific conditions of the present application are not limited to the conditions mentioned above.
[0029] The bacteriostatic deodorizing substances can be a certain plant and / or plant extract, or a mixture of multiple plants and / or plant extracts. In an embodiment, the bacteriostatic deodorizing substances are in powder form, and the bacteriostatic deodorizing substances are derived from natural plants such as green tea, motherwort, comfrey, ginkgo leaves, and jasmine flowers. The bacteriostatic deodorizing substances include one or more of green tea extract, motherwort extract, comfrey extract, ginkgo leaves, and jasmine flowers. Tea polyphenols in green tea, flavonoids in motherwort, and shikonin in comfrey can effectively inhibit the growth and reproduction of harmful bacteria such as Staphylococcus aureus and Escherichia coli. Tea polyphenols and ginkgo leaves can also decompose ammonia, hydrogen sulfide, and other odor substances in feces. Jasmine is a fragrance substance that masks the odor of feces, urine, and other odors. These effective ingredients are extracted by an organic solvent and freeze-dried into a powder for mixing to achieve the effects of bacteriostasis, deodorization, and soothing.
[0030] The capsule wall 331 is a polymer film, which can be a modified protein substance, for example, animal protein such as whey protein, gelatin, or casein. The processing characteristics of animal protein are better than those of plant protein. The stability, density, and solubility of the animal protein are changed by chemical / physical methods to make the finally prepared wall material well-embedded and protect the capsule core 332. When the wall material encounters a liquid with a temperature exceeding 37℃, it will gradually swell and dissolve, allowing the substances in the capsule core 332 to be slowly released to play a role.
[0031] The bacteriostatic and deodorizing diaper of the present application uses bacteriostatic and deodorizing substances as the capsule core 332, and the capsule wall 331 covers the capsule core 332 to form microcapsules. The capsule wall 331 wraps the bacteriostatic and deodorizing substances, so that the active ingredients of the bacteriostatic and deodorizing substances are not affected by external temperature and humidity, light, and oxygen, the stability of the bacteriostatic and deodorizing substances can be improved, and the natural activity of the bacteriostatic and deodorizing substances is protected. During use, the capsule core 332 is slowly released from the capsule wall 331 under specific conditions, the bacteriostatic and deodorizing substances can inhibit the reproduction of pathogenic bacteria and decompose hydrogen sulfide, ammonia and other odor substances in feces, and have a soothing effect on the buttocks to a certain extent, thereby solving the problem of bacterial growth and odor generation caused by long-term use of diapers.
[0032] In an embodiment, the absorbent core 30 further comprises wood pulp and high molecular water-absorbing resin 333, and the wood pulp and high molecular water-absorbing resin 333 are wrapped in the space enclosed by the upper wrapping non-woven fabric 31 and the lower wrapping non-woven fabric 32. In a specific embodiment, the microcapsules 33 are mixed with the wood pulp and high molecular water-absorbing resin 333 in the absorbent core 30 in a ratio of 1:5:4 to form a mixture.
[0033] In an embodiment, as shown in Figure 2 the upper wrapping non-woven fabric covers the top side of the plurality of microcapsules 33, and the lower wrapping non-woven fabric includes a bottom portion 321, an annular side portion 322, and a top portion 323. The bottom portion 321 is arranged on the side of the plurality of microcapsules 33 away from the upper wrapping non-woven fabric, the annular side portion 322 is arranged around the side of the upper wrapping non-woven fabric and the plurality of microcapsules 33, and the top portion 323 is connected to the side of the upper wrapping non-woven fabric away from the plurality of microcapsules 33. The two ends of the annular side portion 322 are connected to the bottom portion 321 and the top portion 323 respectively, so that the plurality of microcapsules 33 are wrapped between the upper wrapping non-woven fabric and the lower wrapping non-woven fabric 32.
[0034] In an embodiment, as shown in Figure 1 the bottom non-woven fabric 50 includes a central portion 51, a first side portion 52, and a second side portion 53. Along the width direction of the bottom non-woven fabric 50, the first side portion 52 and the second side portion 53 are respectively connected to the two ends of the width direction of the central portion 51. The first side portion 52 is provided with a first opening 521, and the second side portion 53 is provided with a second opening 531. The first opening 521 and the second opening 531 are used to accommodate the two legs of a human body when the diaper is worn. After the front adhesive member 60 and the rear adhesive member 70 are adhered together, the first opening 521 and the second opening 531 are respectively located at the two opposite side waists of the human body.
[0035] In an embodiment, as shown in Figure 1As shown, the front adhesive member 60 is arranged on the central portion 51, the first side portion 52 and the second side portion 53 of the first end 80, and the number of the rear adhesive member 70 is two, which are arranged on the first side portion 52 of the second end 90 and the second side portion 53 of the second end 90, respectively.
[0036] In an embodiment, the rear adhesive member 70 is a magic tape, so that the front adhesive member 60 and the rear adhesive member 70 can be repeatedly adhered, which can facilitate the user to adjust the tightness.
[0037] In an embodiment, the hydrophilic surface layer 10 is a hydrophilic non-woven fabric, which can be a hot air cloth, a spun-bonded cloth, a pure cotton spunlace cloth or a non-woven fabric mixed by heat sealing, glue complex, water jet and other technologies. The flow layer 20 is a single-layer hot air non-woven fabric, which helps the liquid to quickly infiltrate by controlling different porosities.
