Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to an ammonia-removing skin-care core and a trouser-type absorbent. Background Art

[0002] Urine is rich in amino acids, proteins and other products, which will produce ammonia and ammonia-like substances over time. Therefore, for disposable urine pants-type absorbents (such as diapers), it is necessary to design a core that can effectively remove ammonia and ammonia-like substances. Since such pants-type absorbents are generally worn on people, they also need to have a skin care effect to avoid irritation to the skin caused by urine and the pants-type absorbents themselves.

[0003] The patent application number of the authorization announcement on August 16, 2019 is CN209253355U, and the name is "An ammonia-removing antibacterial skin-care diaper". It discloses an ammonia-removing antibacterial skin-care diaper, whose surface layer is made of an antibacterial skin-care surface layer made of materials containing polyhexamethylene guanidine, SOD, and vitamin E. The water-absorbing layer of the diaper is made of materials containing sodium carbonate, thymol, and polyhexamethylene guanidine. The water-absorbing layer with ammonia-removing and antibacterial properties is made by spraying the above materials into a solution on the water-absorbing layer of an ordinary diaper, and a layer of non-woven fabric material with the function of removing acidic components in urine and antibacterial is implanted between the surface layer and the water-absorbing layer of the diaper. The diaper has antibacterial and ammonia-removing effects and is non-irritating to the skin. However, the ammonia removal functional layer it uses is not multi-layered, and the ammonia removal substance is mainly attached to the water-absorbing layer of the diaper by spraying. The types of ammonia removal substances that can be used are limited (and this type of ammonia removal substance is less effective than high-molecular ammonia removal substances) and the amount of ammonia removal substance attached is limited, so the ammonia removal effect is limited. Utility Model Content

[0016] Beneficial Effects

[0017] The ammonia removal skin care core described in the utility model has the advantage that it has a water absorption functional layer, an ammonia removal water absorption functional layer and an ammonia removal non-woven fabric layer. The water absorption functional layer and the ammonia removal water absorption functional layer can cooperate to absorb moisture in urine, and the ammonia removal water absorption functional layer and the ammonia removal non-woven fabric layer can cooperate to remove ammonia and ammonia substances in urine. The ammonia removal substance of the ammonia removal non-woven fabric is distributed in a grid-like manner on the surface of the non-woven fabric body, which can reduce the consumption of ammonia removal substances while improving the ammonia removal effect, thereby improving the cost performance of the product. For example, its water absorption functional layer adopts sodium polyacrylate with strong water absorption function, which can effectively absorb moisture in urine, and the ammonia removal water absorption functional layer adopts sodium acrylate-quaternary ammonium salt copolymer with both strong water absorption function and acidic chain segment. Since the quaternary ammonium salt chain segment is acidic and has a bactericidal effect, it can reduce the pH value of urine and kill ammonia-producing bacteria, thereby promoting the volatilization and removal of ammonia, and the sodium acrylate chain segment has a strong absorption function, which can absorb or further absorb moisture in urine. In addition, for example, the ammonia-removing nonwoven fabric layer is the contact layer of human skin. The yucca extract in the prior art can not only protect the skin from irritation due to the use of non-irritating plant extracts, but also remove part of ammonia and ammonia-like substances at the same time, thereby improving the removal effect of ammonia and ammonia-like substances. The trouser-type absorbent described in the utility model includes the ammonia-removing skin care core in all technical solutions of the utility model, so it has all the advantages of the ammonia-removing skin care core.

[0038] like Figure 3 As shown, the middle layer 100 is made of fluffy cloth, and the fluffy cloth adopts the fluffy cloth in the prior art. Those skilled in the art can select the fluffy cloth in the prior art according to actual needs. The second surface layer 310 is arranged below the middle layer 100, and the second surface layer 310 is made of ammonia-removing non-woven fabric, and the ammonia-removing non-woven fabric can adopt the ammonia-removing non-woven fabric in the prior art.

[0039] According to the above technical solution, further, the bonding method among the middle layer 100, the first surface layer 210, 220, the second surface layer 310, 320, the first interlayer 410, 420, and the second interlayer 510, 520 is a bonding method in the prior art such as thermal bonding, self-bonding, and adhesive bonding.

[0040] The above bonding method has the advantages of skin-friendliness, good bonding ability, and easy processing.

[0041] According to the above technical solution, further, the ammonia-removing nonwoven fabric comprises a nonwoven fabric body and an ammonia-removing layer, and the ammonia-removing layer is attached to at least one surface of the nonwoven fabric body.

[0042] The nonwoven fabric body can be a common nonwoven fabric or a medical nonwoven fabric. When the ammonia removal layer is attached to one surface of the nonwoven fabric body, generally speaking, the surface to which the ammonia removal layer is attached is the surface of the core body close to the skin, so that urine can fully contact the ammonia removal layer, so that the ammonia removal substance in the ammonia removal layer can react with urine to the maximum extent, thereby removing ammonia gas and ammonia-like substances in urine. When the ammonia removal layer is attached to both surfaces of the nonwoven fabric body, urine not only contacts the surface of the nonwoven fabric body close to the skin, but also passes through the nonwoven fabric body and contacts the ammonia removal substance in the ammonia removal layer on the other surface thereof, so that urine can further react with the ammonia removal substance on the other surface to remove ammonia gas and ammonia-like substances in urine.

[0043] According to the above technical solution, further, the ammonia removal layer is made of yucca extract.

[0044] The yucca extract is the yucca extract in the prior art. Those skilled in the art can select the yucca extract in the prior art according to actual needs. Since the yucca extract is a plant extract, it has strong adhesion on non-woven fabrics, good ammonia removal effect, and will not irritate the skin, and has good ammonia removal and skin care effect.

[0045] According to the above technical solution, further, the ammonia removal layer has a mesh structure, and the mesh shape is elliptical, quasi-elliptical or polygonal.

[0046] When the ammonia removal layer is in a mesh structure, the ammonia removal substance is distributed in a mesh on the nonwoven fabric body, which can improve the ammonia removal effect while reducing the use of the ammonia removal substance, thereby improving the cost performance of the product. When the mesh of the ammonia removal layer is elliptical, quasi-elliptical or polygonal, the ratio of the contact surface of the ammonia removal substance and urine and the amount of the ammonia removal substance is within a preferred range, which can improve the ammonia removal effect while reducing the use of the ammonia removal substance, thereby improving the cost performance of the product.

[0047] According to the above technical solution, further, the ammonia removal and water absorption functional layer is made of sodium acrylate-quaternary ammonium salt copolymer.

[0048] The sodium acrylate-quaternary ammonium salt copolymer has a sodium acrylate segment with a strong water absorption function and a quaternary ammonium salt acidic segment with a good ammonia removal function. Since the quaternary ammonium salt segment is acidic and has a bactericidal effect, it can reduce the pH value of urine and kill ammonia-producing bacteria, thereby promoting the volatilization and removal of ammonia, while the sodium acrylate segment has a strong absorption function and can absorb or further absorb water in urine. Therefore, the ammonia removal and water absorption functional layer made of the sodium acrylate-quaternary ammonium salt copolymer has a good ammonia removal and water absorption function.

[0049] According to the above technical solution, further, the water absorbing functional layer is made of sodium polyacrylate.

[0050] Sodium polyacrylate has a strong water absorbing function, so the water absorbing functional layer has a good water absorbing function.

[0051] According to the above technical solution, further, there is a glue layer 610 between the first surface layer 210 and the first interlayer 410, there is a glue layer 620 between the first surface layer 220 and the first interlayer 420, there is a glue layer 630 between the second surface layer 310 and the second interlayer 510, and there is a glue layer 640 between the second surface layer 320 and the second interlayer 520.

[0052] The adhesive layer 610 can make the first surface layer 210 and the first interlayer 410 bonded together, the adhesive layer 620 can make the first surface layer 220 and the first interlayer 420 bonded together, the adhesive layer 630 can make the second surface layer 310 and the second interlayer 510 bonded together, and the adhesive layer 640 can make the second surface layer 320 and the second interlayer 520 bonded together. The adhesive layers 610, 620, 630, 640 can play a bonding role to prevent the first surface layer 210, 220 and the first interlayer 410, 420 from falling apart, and prevent the second surface layer 310, 320 and the second interlayer 510, 520 from falling apart.

[0053] According to the above technical solution, further, the adhesive layers 610, 620, 630, 640 are made of pressure-sensitive hot-melt adhesive.

[0054] The specific preparation method is to spray the pressure-sensitive hot melt adhesive on the outer surface of the first interlayer 410 by spraying in a dot-shaped spraying, line-shaped spraying, mesh-shaped spraying or surface-shaped spraying to form the adhesive layer 610, spray on the outer surface of the first interlayer 420 to form the adhesive layer 620, spray on the outer surface of the second interlayer 510 to form the adhesive layer 630, and spray on the outer surface of the second interlayer 520 to form the adhesive layer 640. The pressure-sensitive hot melt adhesive has the characteristics of skin-friendly, easy to melt, and good bonding performance, and is suitable for the preparation of sanitary products. Medical-grade pressure-sensitive hot melt adhesive is generally used in sanitary products.

[0055] According to the above technical solution, further, the pressure-sensitive hot melt adhesive is SBS.

[0056] In addition to the advantages of pressure-sensitive hot melt adhesive, SBS pressure-sensitive hot melt adhesive also has good temperature resistance, strong anti-aging ability, strong stability, high initial adhesion and peeling strength. Therefore, it has strong long-term bonding ability and is suitable for the preparation of sanitary products.

[0057] The utility model also provides a trouser-type absorbent, comprising the ammonia-removing skin-care core described in the above technical solution.

[0058] For example, the pants-type absorbent article can be a diaper, sanitary pants, etc.

[0059] For example, the preparation process of the ammonia removal skin care core is as follows;

[0060] A layer of the ammonia removal substance is coated on at least one surface of the non-woven fabric body to form the ammonia removal layer and the ammonia removal non-woven fabric, wherein the ammonia removal layer is a mesh structure. For example, the mesh shape can be selected from Figure 4 The oval shape shown in the figure, the ammonia-removing nonwoven fabric is as follows Figure 4 shown.
