Description
Technical Field
The utility model relates to an absorbent sanitary goods technical field especially relates to a ventilative type absorbent sanitary goods.
Background
Conventional absorbent hygiene articles (e.g., sanitary napkins, pantiliners, diapers, etc.) generally include a top layer, an intermediate absorbent layer, and a bottom layer. The surface layer is a contact layer and is generally designed to be a soft surface layer so as to improve the touch feeling; the absorption layer is used for absorbing liquid; the bottom layer is designed to be a liquid-tight layer to prevent the absorbed liquid from leaking and making the clothes dirty.
For such absorbent sanitary articles, stuffy and airproof is a considerable problem associated with wearing. During the development of the product, we find that, in order to improve the breathability of the product, the existing methods generally include the following methods: one is to eliminate the stuffiness feeling of the product after imbibing by improving the surface material; one is to improve the air permeability of the product by designing air permeable and ventilating structures such as air permeable holes or ventilating areas, and the other is to improve the air permeability of the product after absorbing liquid by endowing the absorbing layer with fluffy and three-dimensional structural characteristics. However, we have found that in the current market products, the bottom layer of the product is mostly made of PE base film such as cast film, blown film and the like. The general air permeability of PE material leads to the consumer still feel stuffy, moist and airtight during the use process. In addition, although some products improve the air permeability, the light and thin products cannot be guaranteed. For example, CN201220627383.1 discloses a liquid-absorbing, air-permeable and leak-free sanitary napkin, in which the core of the sanitary napkin is composed of a skin-friendly dry layer and three air-permeable liquid-storing core layers, and each air-permeable liquid-storing core layer is composed of a flow-guiding, air-permeable layer, a liquid-storing, air-permeable layer and a liquid-repellent, air-permeable layer. Because the absorption core is overlapped by three liquid storage core layers, the product thickness cannot be guaranteed to be light and thin, the air permeability cannot be improved more, and the liquid-repellent layer is water-repellent paper or textile cloth, so that the water-repellent effect cannot be guaranteed to be optimal.

Detailed Description
In order to make the purpose, technical solution and advantages of the present invention clearer, the following embodiments of the present invention will be combined to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a ventilative type absorbability sanitary product, including absorbing the body, absorbing the body and including contact surface top layer, middle absorbed layer and bottom in proper order. Wherein the bottom layer is an SMMS spunbonded non-woven fabric layer, and the single-layer gram weight of the SMMS spunbonded non-woven fabric layer is not less than 25g/m2And the number of layers is not less than 2.
< bottom layer >
The SMMS spunbonded non-woven fabric (Spunbonded + Meltbwn + Spunbonded nonwoven) belongs to a composite non-woven fabric material, is an existing material in the current market, and can be purchased through a market or prepared by an existing method. The utility model discloses improve the bottom, adopt SMMS to glue the bottom that non-woven fabrics layer as absorbent sanitary goods. The SMMS spunbonded non-woven fabric is water-repellent, oil-repellent and blood-repellent spunbonded non-woven fabric, can improve the air permeability of a product and is light and thin when used as a water-repellent bottom layer of an absorbent sanitary product, and the air permeability of the product is far better than that of a PE film, so that the high-end performance of the product is highlighted.
However, since the absorbent sanitary article undergoes a significant change in the weight after liquid absorption, the permeability of the absorbent layer located on the upper layer of the backsheet, and the like. The bottom layer, as a liquid-impermeable layer, needs to ensure not only breathability but also ability to cooperate with the middle absorbent layer to ensure performance after imbibition. It is not feasible to use any SMMS spunbond nonwoven layer as the bottom layer. Intensive and extensive research into this has been conducted by research and development groups, and suitable SMMS spunbond nonwoven layer structures have been discovered.
(1) Single layer grammage of SMMS spunbonded nonwoven layer
SMMS spunbondThe single-layer gram weight of the non-woven fabric layer is not less than 25g/m2Preferably 25 to 80g/m2For example, it may be 25g/m2，30g/m2，35g/m2，40g/m2，45g/m2，50g/m2，55g/m2，60g/m2，65g/m2，70g/m2，75g/m2，80g/m2. The inventors have found that when the SMMS spunbond nonwoven layer has a single layer grammage of less than 25g/m2When the spun-bonded non-woven fabric is used, the gram weight of the spun-bonded non-woven fabric is too low, the bottom layer has poor blood-repellent effect, even blood seepage can be caused, the liquid absorption amount of the product is limited, and the spun-bonded non-woven fabric is not suitable for the condition of large liquid absorption amount. But not too high, when the single-layer gram weight of the SMMS spunbonded non-woven fabric layer is more than 80g/m2During the process, the gram weight of the non-woven fabric is too high, the thickness is obviously improved, the overall softness of the absorbing article is obviously reduced, and the wearing comfort level of a user is seriously influenced.
In some more preferred embodiments, the SMMS spunbond nonwoven layer has a single layer grammage of 35 to 60g/m2。
(2) Number of layers of SMMS spunbonded nonwoven fabric layer
The number of layers of the SMMS spunbond nonwoven layer is not less than 2, preferably 2 to 5, and for example, may be 2, 3, 4, 5. The inventor finds that when the number of layers of the SMMS spunbonded nonwoven fabric layer is less than 2, the number of layers of the spunbonded nonwoven fabric is too small, so that the leakage prevention effect of the bottom layer is not ideal, and the probability of bleeding is very high. But also should not have too many layers, and when the number of layers of SMMS spunbonded nonwoven fabric layer is higher than 5 layers, the number of layers of spunbonded nonwoven fabric is too high, easily causes the thickness of absorbent article great, and the compliance is poor, influences user's wearing travelling comfort.
In some more preferred embodiments, the number of layers of the SMMS spunbond nonwoven layer is 2 to 3.
The SMMS spunbonded non-woven fabric layer structure with the single gram weight and the number of layers can be matched with the absorption cores with different absorption effects, and good product performance can be obtained. Even if the absorption layer of the upper layer is a composite absorption core body with extremely strong absorption capacity, the bottom layer still has good air permeability after absorbing liquid, and liquid leakage cannot occur.
The SMMS spunbonded nonwoven fabric layer structure with the single gram weight and the layers can meet the requirements of consumers in different levels, and the overall thickness of the product can be thinner and can ensure air permeability.
In actual production, the single-layer gram weight of the SMMS spunbonded nonwoven fabric layer is controlled to be 25-80g/m2(more preferably 35 to 60 g/m)2) Or controlling the number of SMMS spunbonded nonwoven layers to be 2-5 layers (more preferably 2-3 layers) can obtain the absorbent sanitary product with better air permeability and light weight and thin performance. The best proposal is to simultaneously control the single-layer gram weight of the SMMS spunbonded nonwoven fabric layer to be 25-80g/m2(more preferably 35 to 60 g/m)2) And the number of the SMMS spunbonded nonwoven fabric layers is 2-5 (more preferably 2-3), so that the air permeability of the product can be improved to the greatest extent on the basis of ensuring the light and thin performance of the product.
In some preferred embodiments, the bottom layer has the following structure: the grammage of each SMMS spunbonded non-woven fabric layer is the same and/or different; further preferably, the grammage of each SMMS spunbond nonwoven layer is different and increases from top to bottom.
The material of the SMMS spunbond nonwoven fabric layer is preferably polypropylene. The polypropylene spun-bonded non-woven fabric has the advantages of air permeability, water resistance, no toxicity, no odor, sterility and the like.
< intermediate absorber layer >

For example, the middle absorbent layer is a composite absorbent core structure, which comprises 5 layers of structures, from top to bottom, respectively, a layer of dust-free paper (or spun-bonded nonwoven fabric), a layer of super absorbent resin, a layer of fluffy fiber, a layer of super absorbent resin, and a layer of dust-free paper (or spun-bonded nonwoven fabric), and the raw materials of the layers are bonded together by an adhesive. For another example, the intermediate absorbent layer is a composite absorbent core structure, and comprises 7 layers of dust-free paper (or spun-bonded nonwoven fabric), superabsorbent resin, bulky fibers, superabsorbent resin, and dust-free paper (or spun-bonded nonwoven fabric) from top to bottom, and the above raw materials are bonded together by an adhesive. It should be noted that the super absorbent resin is a material conventional in the art, such as any one or more of starch grafted acrylate, grafted acrylamide, highly substituted cross-linked carboxymethyl cellulose, cross-linked carboxymethyl cellulose grafted acrylamide, and cross-linked hydroxyethyl cellulose grafted acrylamide polymer. The composite absorbent core structure enumerated above contributes to the overall absorption rate and absorption capacity of the product. The improvement can be made on the basis that: the middle position of the absorption layer is provided with the flow guide structure, such as the flow guide seam and/or the flow guide groove, the infiltration and diffusion speed and the absorption speed of liquid can be further accelerated, body fluid can be rapidly diffused, the absorption speed, the diffusion length and the absorption area are increased, and therefore reverse infiltration is reduced, the dryness and comfort of the product are improved, and the product is more comfortable and safer to use. The forming process of the flow guide structure can be knife cutting or cold pressing or hot pressing of a die. The flow directing structure may be directional.
