Description

Technical Field

[0001] The present invention relates to the field of female hygiene products, and more particularly to a hygiene product with a healthy microenvironment. Background Art

[0002] Sanitary napkins are sanitary products used by women during menstruation. The main materials are polymers and polymer composite paper formed by cotton, non-woven fabrics, pulp or composites of the above materials. The side design is mainly used to prevent side leakage. From the inside to the outside, it is divided into three layers: surface layer, absorbent core and bottom layer. As a disposable sanitary product, sanitary napkins play an increasingly important role, especially in terms of physiological health needs. Sanitary napkins can effectively absorb menstrual blood and bring comfort and protection to women. During use, the sanitary napkin needs to be flatly pasted on the bottom of the underwear, ensuring that the front of the sanitary napkin faces up so that it can better absorb menstrual blood. With the development of social economy and the improvement of women's health awareness, the market consumption of women's sanitary products continues to increase. Among women's sanitary products, sanitary napkins occupy the forefront of the market with an absolute advantage. In the context of consumption upgrading, people are paying more and more attention to the practicality and comfort of sanitary napkin products.

[0003] The absorption of menstrual blood by sanitary napkins in the prior art is still limited, especially when the amount of menstrual blood of female users is heavy. The menstrual blood on the surface of the sanitary napkin will give the user a poor visual experience, which is especially unfriendly to women who are afraid of blood. On the other hand, after the existing sanitary napkins absorb the menstrual blood, the menstrual blood is always close to the surface of the skin, causing the microenvironment between the sanitary napkin and the skin to be affected. Summary of the invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a sanitary product with a healthy microenvironment, which is used to dilute blood stains on the sanitary product and improve the microenvironment.

[0005] The technical solution adopted by the present invention is to provide a sanitary product for a healthy microenvironment, comprising: a main body, and side wings arranged on both sides of the main body; the main body comprises: a surface layer, a composite absorption layer and a bottom layer; a rolled and compressed folded liquid-conducting layer is arranged between the surface layer and the composite absorption layer; a wetting-failure packaging structure is arranged on the folded liquid-conducting layer, so that the compression state of the folded liquid-conducting layer can be released when the packaging structure is exposed to liquid.

[0006] In this scheme, the surface layer is a layer in contact with the human body, and the bottom layer is a layer in contact with clothing. When the menstrual blood passes through the surface layer and contacts the folded liquid-conducting layer, it is quickly absorbed into the composite absorption layer, and then absorbed and locked. When the amount of liquid is small, the diffusion of blood in the folded liquid-conducting layer is small, and the blood stains are not obvious. When the amount is large, the diffusion surface in the folded liquid-conducting layer increases, and the part of the folded liquid-conducting layer that contacts the liquid increases. When the packaging structure contacts the menstrual blood, the packaging and compression of the folded liquid-conducting layer are released, and the folded liquid-conducting layer compressed by the package is unfolded with its own tension, and changes from the original compressed state to an expanded state, so that the blood that was originally in the compressed state is dispersed in the process of fiber opening, and the distance between the composite absorption layer that mainly absorbs the menstrual blood and the surface of the folded liquid-conducting layer is pulled away, and the covering effect is improved under the dual effect, and the effect of visually diluting the blood stains is obtained, thereby keeping the visual cleanliness of the surface of the sanitary products, and being friendly to users who are afraid of blood, increasing user acceptance, and for merchants, it can also expand the user group and improve the sales prospects of products. At the same time, the thickness of the expanded folded liquid-conducting layer is increased, which can fit the curve of the female body, thus improving the fit of the absorbent core, effectively preventing side leakage and rear leakage, and further optimizing the user experience.

[0007] In addition, since the liquid is almost absorbed and locked in the composite absorption layer after passing through the folded liquid conduction layer, the surface of the sanitary product is dry, and there is a folded liquid conduction layer between the blood and the skin, which avoids the increase of bacteria around the skin due to the contact of a large amount of blood with the skin. This reduces the risk of infection for the user, provides a healthy microenvironment for the user's skin, and is beneficial to the user's health.

[0008] Furthermore, if it is a traditional multi-layer structure, each layer is stretched out and the compression effect cannot be achieved. The rolled compression setting of the folded liquid-conducting layer allows it to maintain a continuous whole, improving the structural stability. At the same time, the continuous rolled folded liquid-conducting layer as a whole allows the surface layer to clamp the middle layer through the locking of the packaging structure when it is a multi-layer structure, directly compressing the middle layer, and further achieving an ultra-thin effect through a simple structure.

[0009] In addition, the rolled folded liquid-conducting layer structure facilitates the release of the compressed state after the packaging structure fails, allowing it to expand and loosen in the direction of opening and folding through its own tension; and the folded liquid-conducting layer makes it have more than one layer of structure, ensuring its shielding effect on blood stains of the composite absorption layer below, while increasing the expanded thickness to ensure its fit to the female parts.

[0010] Preferably, the folded liquid-conducting layer is made of fluffy hydrophobic fibers, and the folded liquid-conducting layer is in the shape of an integral long strip and is folded to form a compressed structure including at least three sub-layers.

[0011] In the present technical solution, the fluffy hydrophobic fiber material can provide more compression space, which is convenient for compressing the folded liquid-conducting layer into an ultra-thin structure, greatly reducing the overall thickness of the sanitary product; the fluffy hydrophobic fiber material can also be conducive to the expansion of the folded liquid-conducting layer after the compression state is released, ensuring its fitting effect and the shielding effect of the blood stains on the composite absorption layer; at the same time, the hydrophobic fiber itself is expanded to enlarge the fiber gap, disperse the blood remaining in the fiber gap, and visually dilute the blood stains of the folded liquid-conducting layer; furthermore, the fluffy material has a porous nature, which is convenient for menstrual blood to pass through the folded liquid-conducting layer and quickly enter the composite absorption layer for locking and absorption, preventing menstrual blood from staying in the liquid-conducting layer, thereby keeping the surface of the sanitary product dry, that is, the setting of the fluffy structure of the folded liquid-conducting layer itself is also conducive to avoiding the environment between the user's skin and the sanitary product from being too humid, thereby preventing bacteria from growing, which is conducive to the balance of the flora and providing a healthy microenvironment for the user's skin; in addition, the fluffy setting also reduces the overall weight, making the sanitary product lighter as a whole and providing a better user experience.

[0012] The long strip shape of the folded liquid-conducting layer matches the long strip shape of the sanitary product, so that after the folded liquid-conducting layer is unfolded, the front and rear positions of the sanitary product can block blood stains, while expanding the contact surface with the user's body parts, improving comfort and fit when not expanded, and can increase and increase the diversion effect; the setting of at least three sub-layers ensures the blocking effect of blood stains on the composite absorption layer, while increasing the thickness after unfolding to improve the fit effect, and further prevent side leakage or rear leakage.

[0013] Preferably, the folded liquid-conducting layer is provided with an opening, and the opening is formed on one side of the uppermost sub-layer; the encapsulation structure is a glue line, and the glue line is provided in the opening so that the opening is closed.

[0014] In the present technical solution, when the packaging structure is loosened, the top sub-layer expands and moves in the direction of increasing the opening, that is, its movement direction is toward the surface layer, which is conducive to its fit with the human body; and because menstrual blood flows from top to bottom, setting the opening at the top sub-layer can make the packaging structure loosen when the upper side of the folded liquid-conducting layer contacts the menstrual blood, thereby increasing the speed at which the folded liquid-conducting layer is released from the compressed state, timely shielding the blood stains on the composite absorbent layer, diluting the blood stains, and further optimizing the user experience.

[0015] Preferably, the width of the glue line is 1.5 mm to 2.5 mm, the tensile strength of the glue line after being wetted is no higher than 0.2 N, and a gap is left between the glue line and the extension of the opening.

[0016] In the present technical solution, the setting of the tensile force not higher than 0.2N can prevent the glue line from being too difficult to loosen, resulting in the folded guide layer being unable to release the compression state, thereby affecting the bloodstain dilution effect and the bonding effect; at the same time, the appropriate setting of the glue line width can also prevent it from being too easy to loosen, resulting in the product being loosened during transportation and movement, resulting in the thickness of the liquid guide layer being too large, affecting the menstrual blood from passing through the layer into the composite absorption layer, or this resulting in waste of manpower and material resources caused by product rework. Furthermore, the setting of the interval can provide protection for the packaging structure to prevent it from being exposed, thereby reducing the risk of being accidentally touched; the width of the interval is preferably 0.5mm to 2mm, and the appropriate setting of the width can prevent the distance between the locking structure and the edge of the opening from being too long, thereby ensuring that the locking structure is not too difficult to be triggered and unlocked, so that its function can be performed normally, and at the same time, it also avoids the formation of wrinkles or eversion at the edge of the first expansion layer. That is, in this solution, the width of the glue line, the tensile strength of the glue line after it is wetted, and the interval are combined to ensure that the glue line can firmly adhere to the sub-layer of the liquid-conducting layer before it gets wet, thereby reducing the product turnover rate, saving production costs, and improving production efficiency. At the same time, its premature loosening will cause it to be too thick and affect the user's use; and the glue line can be easily loosened after it gets wet, thereby ensuring the bloodstain dilution effect and self-adhesive effect.

[0017] Preferably, the connected side of the sub-layers faces the side wing; the thickness of the folded liquid-conducting layer before decompression is 0.4 mm to 0.8 mm, and the thickness of the folded liquid-conducting layer after decompression is 5 to 7 times the thickness before decompression.

[0018] In this technical solution, the appropriate thickness setting of the folded liquid-conducting layer before the compression is released makes the sanitary product thinner as a whole, improving the user's comfort level. At the same time, thinner sanitary products can save packaging space, thereby saving packaging costs and facilitating transportation. The thickness setting before contact compression is combined with the setting of increasing the thickness to 5 to 7 times after the compression state is released, so that the folded liquid-conducting layer in the expanded state has enough thickness to cover the blood stains of the composite absorbent layer and achieve self-adhesion, while avoiding excessive thickness that affects the transfer speed of menstrual blood and the user's comfort level.

[0019] Preferably, a light-colored composition is provided in the folded liquid-conducting layer; the light-colored composition comprises: monounsaturated fatty acid inclusions, a surfactant and a carrier solvent; the mass ratio of the unsaturated fatty acid inclusions to the surfactant is (2.1-2.3):1.

[0020] In this technical solution, menstrual blood is composed of blood, endometrial tissue fragments, cervical mucus, plasmin and other components, and the color of menstrual blood is mostly derived from hemoglobin in the blood; the light-colored composition can oxidize hemoglobin and turn it into a whitish yellow, thereby achieving the purpose of lightening menstrual blood. Through the light-colored composition and the structural setting of the folded liquid-conducting layer itself, the dual protection of physical lightening and chemical lightening is achieved, so that even when the amount of menstrual blood is large, the blood stains can still be effectively lightened, further optimizing the user experience.

[0021] Preferably, the desalination composition is wrapped by microcapsules and then sprayed on the surface of the folded liquid-conducting layer and penetrates into the folded liquid-conducting layer. After spraying, the folded liquid-conducting layer is dried to allow the desalination composition to combine with the fibers in the folded liquid-conducting layer.

[0022] In the present technical scheme, the lightening composition is wrapped in microcapsules and sprayed, and both the surface and the interior are covered, so that the microcapsules can be evenly dispersed on the folded liquid-conducting layer, so that the menstrual blood distributed in various parts of the folded liquid-conducting layer can be fully lightened; when the blood enters the folded liquid-conducting layer, especially when it hovers on the fibers, it can fully react and further eliminate blood stains; after drying, the carrier solvent evaporates, and the effective light-coloring components are combined with the fibers in the folded liquid-conducting layer through a simple operation process, which is suitable for mass production; and the light-coloring material can be firmly combined with the folded liquid-conducting layer through spraying and drying to prevent it from falling during transportation and movement and affecting the light-coloring effect.

[0023] Preferably, the composite absorbent layer comprises: wood pulp, SAP and wet-strength paper; the wood pulp and SAP are mixed to form an absorbent core layer, and the wet-strength paper is used to wrap the absorbent core layer.

[0024] In the present technical solution, wood pulp has good water conductivity, and SAP is a highly absorbent resin with super strong water absorption, which can quickly absorb a large amount of liquid. The absorption core layer formed by mixing wood pulp and SAP is not only ultra-thin but also can achieve strong absorption of menstrual blood, and quickly lock the menstrual blood. Its strong absorption capacity avoids the accumulation of large amounts of menstrual blood and reverse osmosis to the folded liquid-conducting layer above it, further ensuring the dilution effect of blood stains, and at the same time preventing side leakage and rear leakage. The absorption effect can be further enhanced by wet-forcing the absorption core layer. Since the folded liquid-conducting layer is made of hydrophobic fiber material, liquid can quickly pass through the liquid-conducting layer, and then enter the composite absorption layer to be absorbed and locked, thereby achieving the purpose of preventing liquid from staying on the surface of sanitary products, keeping the surface of sanitary products dry, and at the same time achieving the purpose of blocking blood stains on the composite absorption layer.

[0025] Preferably, the composite absorbent layer is further wrapped with a coarse fiber cloth layer.

[0026] In the technical solution, the coarse fiber cloth plays an absorption and diversion role, draining the menstrual blood to the absorbent core layer inside it for locking.

[0027] Preferably, the composite absorbent layer has a grammage of 300 gsm to 500 gsm;

[0028] The thickness of the composite absorption layer before absorbing liquid is 0.35 to 0.5 mm, and the maximum thickness after absorbing liquid is 10 to 20 times that before absorbing liquid;

[0029] The width of the composite absorption layer is 1.5 to 2 times that of the folded liquid-conducting layer.

[0030] In this technical solution, the appropriate weight setting allows the sanitary products to remain thin and light while ensuring water absorption. The appropriate setting of the thickness of the composite absorption layer before absorbing liquid is conducive to maintaining a thinner appearance of the sanitary products as a whole. The expanded thickness and width after absorbing liquid are appropriately increased so that it will not be too thin to affect the absorbency, nor will it affect the user's comfort due to being too thick. At the same time, it prevents the excessive thickness from increasing the path of blood passing through the folded liquid conduction layer, resulting in an increased probability of residue and hindering blood transfer. In this solution, the thickness or width of the composite absorption layer before and after absorbing liquid is coordinated with the thickness of the folded guide layer, forming a sanitary product that is ultra-thin before absorbing liquid, has super water absorption performance after absorbing liquid, and is light and thin.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) When the folded liquid-conducting layer is released from the compressed state and expands, the menstrual blood absorbed into the composite absorbent layer is covered by the fluffy folded liquid-conducting layer, which visually reduces the blood stains, thereby keeping the surface of the sanitary product clean. It is also user-friendly for those who are prone to bloodsickness, increasing user acceptance, and can also expand the user base for merchants and improve product sales prospects. At the same time, the thickness of the expanded folded liquid-conducting layer increases, which can fit the curve of the female body, thereby improving the fit of the absorbent core and effectively preventing side leakage and rear leakage. Furthermore, by setting up the folded liquid-conducting layer, a greater distance is maintained between the skin and the composite absorbent layer that stores menstrual blood, effectively improving the microenvironment and making the microenvironment healthier.

[0033] (2) By combining the folded liquid-conducting layer and the lightening composition, the dual protection of physical lightening and chemical lightening is achieved, so that even when the menstrual blood volume is heavy, the blood stain can still be effectively lightened, further optimizing the user experience.

[0040] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted. Example 1

[0041] refer to Figures 1 to 4 This embodiment provides a sanitary product for a healthy microenvironment, comprising: a main body, and side wings arranged on both sides of the main body; the main body comprises:

[0042] A surface layer 100, a composite absorbent layer 300 and a bottom layer; a rolled and compressed folded liquid-conducting layer 200 is provided between the surface layer 100 and the composite absorbent layer 300; a wetting-failure packaging structure 240 is provided on the folded liquid-conducting layer 200, so that the compression state of the folded liquid-conducting layer 200 is released when the packaging structure 240 is exposed to liquid.

[0043] In this solution, the surface layer 100 is a layer in contact with the human body, and the bottom layer is a layer in contact with clothing. When the menstrual blood passes through the surface layer 100 and contacts the folded liquid-conducting layer 200, it is quickly absorbed and guided to the composite absorbent layer 300 to be absorbed and locked again. The packaging structure 240 on the folded liquid-conducting layer 200 fails after contacting the menstrual blood. The rolled and compressed folded liquid-conducting layer 200 is opened and changes from the original compressed state to the expanded state. The menstrual blood mainly absorbed into the composite absorbent layer 300 is covered by the fluffy folded liquid-conducting layer 200, and the blood stains are visually diluted, thereby keeping the surface of the sanitary product clean, and being friendly to users who are afraid of blood, increasing user acceptance, and for merchants, it can also expand the user group and improve the product sales prospects. At the same time, the expanded folded liquid-conducting layer 200 has an increased thickness and can fit the curve of the female body, thereby improving the fit of the absorbent core, effectively preventing side leakage and rear leakage, and further optimizing the user experience.

[0044] The rolled compression setting of the folded liquid-conducting layer 200 facilitates the release of the compressed state after the packaging structure 240 fails, ensuring that it can expand and loosen. The folded setting of the liquid-conducting layer makes it have more than one layer of structure, ensuring its shielding effect on the blood stains of the composite absorption layer 300 below, while increasing the expansion thickness to ensure its fit to the female parts.

[0045] Next, the first layer of the sanitary product of this embodiment is described.

[0046] The surface layer 100 is the first layer, which is the skin contact layer. It uses a non-woven sheet and can be composed of only one type of fiber, such as polyester or polypropylene, or it can contain a mixture of more than one fiber. The fibers can be selected from various natural and synthetic materials, such as nylon, Tencel, polyester, cotton, acrylic fiber and the combination thereof. The material can be plain or 3D shaped by roller embossing. Preferably, the gram weight is 20gsm to 35gsm.

[0047] Next, the second layer of the sanitary product of this embodiment will be described.

[0048] refer to Figure 1 and Figure 2 , the folded liquid-conducting layer 200 is the second layer, and the folded liquid-conducting layer 200 is made of fluffy hydrophobic fibers, and the hydrophobic fibers include ES fibers and / or hollow PET polyester fibers and / or PBT fibers and / or PET fibers, and the fiber denier is 3D to 12D. ES fibers have good resilience and recovery properties, and their soft material can reduce friction stimulation to the skin, and have good hygroscopicity and air permeability. Hollow PET polyester fibers are light in weight and have high fluffiness, and can effectively lock the liquid inside. PBT fibers have excellent elongation elastic recovery rate, can well realize the characteristics required by the elastic fiber structure, and the material is soft, effectively avoiding friction stimulation. PET fibers have good resilience and wrinkle resistance, and strong chemical stability. The hydrophobic fiber structure is preferably ES fiber combined with PBT fiber, so that it can maintain a soft and fluffy feel of use, and can maintain excellent resilience, so that the rolled folded liquid-conducting layer 200 can expand and unfold rapidly after being triggered by menstrual blood, and the menstrual blood is diluted and covered to avoid the menstrual blood from staying on the surface of the liquid-conducting layer. The folded liquid-conducting layer 200 can also be ES fiber combined with PBT fiber combined with hollow PET polyester fiber combined with PET fiber, so that the elastic fiber structure not only has the aforementioned advantages, but also can help the absorbent core stay dry in the hot and sweaty environment of summer, thereby improving the user experience of women.

[0049] Preferably, the folded liquid-conducting layer 200 is in the shape of an integral long strip and is folded to form a compressed structure including at least three sublayers. The folded liquid-conducting layer 200 is provided with an opening, which is formed on one side of the sublayer located at the top; the encapsulation structure 240 is a glue line, which is arranged in the opening so that the opening is closed. The side connected between the sublayers faces the side wing. The fluffy hydrophobic fiber material can facilitate the expansion of the folded liquid-conducting layer 200 after contact in a compressed state, ensuring its fitting effect and the shielding effect of the blood stains on the composite absorbent layer 300; at the same time, the fluffy material has a porous property, which facilitates the menstrual blood to pass through the folded liquid-conducting layer 200 and quickly enter the composite absorbent layer 300 for locking and absorption, preventing the menstrual blood from staying in the liquid-conducting layer; in addition, the fluffy setting also reduces the overall weight, making the sanitary product lighter as a whole and providing a better user experience. The long strip shape of the folded liquid-conducting layer 200 matches the long strip shape of the sanitary product, so that the front and rear positions of the sanitary product can block blood stains after the folded liquid-conducting layer 200 is unfolded; the setting of at least three sub-layers ensures the blocking effect of blood stains on the composite absorption layer 300, while increasing the thickness after unfolding to improve the fitting effect, further preventing side leakage or rear leakage.

[0050] Preferably, the thickness of the folded liquid-conducting layer 200 before compression is released is 0.4 mm to 0.8 mm, for example, 0.5 mm, 0.6 mm or 0.7 mm, etc., and the thickness of the folded liquid-conducting layer 200 after compression is released is 5 to 7 times the thickness before compression. The appropriate thickness setting of the folded liquid-conducting layer 200 before compression makes the sanitary products thinner as a whole, improving the user's comfort. At the same time, thinner sanitary products can save packaging space, thereby saving packaging costs and facilitating transportation. The thickness setting before contact compression is combined with the setting of increasing the thickness to 5 to 7 times after the compression state is released, so that the folded liquid-conducting layer 200 in the expanded state has enough thickness to block the blood stains of the composite absorbent layer 300 and achieve self-adhesion, while avoiding excessive thickness that affects the transfer speed of menstrual blood and the user's comfort.

[0051] Preferably, the folded liquid-conducting layer 200 includes three or four sub-layers. An appropriate number of sub-layers ensures the effect of shielding blood stains while preventing too many layers from affecting the menstrual blood from passing through the folded liquid-conducting layer 200 and accumulating menstrual blood in the folded liquid-conducting layer 200. At the same time, too many layers are prevented from causing the layer to be too thick and affecting the comfort of use. Taking the folded liquid-conducting layer 200 with three sublayers as an example, the folded liquid-conducting layer 200 includes a first sublayer 210, a second sublayer 220 and a third sublayer 230 from top to bottom, respectively. The opening is arranged on one side of the first sublayer 210 and the second sublayer 220, and the encapsulation structure 240 closes the opening. When the encapsulation structure 240 is wet, the first sublayer 210 expands and moves in the direction of increasing the opening, that is, its moving direction is toward the human body, which is conducive to its fit with the human body; the side of the first sublayer 210 away from the opening is integrally connected to the third sublayer 230, and the side of the second sublayer 220 is integrally connected to the third sublayer 230 so that the whole presents a rolled structure. The integral connection increases the transmission speed of menstrual blood, further accelerates the menstrual blood to pass through the folded liquid-conducting layer 200 and enter the composite absorption layer 300 for absorption and locking, and avoids the accumulation of menstrual blood in the folded liquid-conducting layer 200.

[0052] Preferably, the packaging structure 240 of the folded liquid-conducting layer 200 can be a glue line, a film seal, a water-soluble film, a water-sol, a water-soluble line or an airbag compression, etc. More preferably, it is a glue line, which is firmly bonded and easy to open when encountering liquid. The width of the glue line is 1.0 mm to 2.5 mm, for example, 1.8 mm, 2 mm or 2.4 mm. The tensile strength of the glue line after wetting is not higher than 0.2 N, for example, 0.1 N, 0.15 N or 0.2 N. There is a gap between the glue line and the extension of the opening. The width of the gap is preferably 0.5 mm to 2 mm, for example, 0.6 mm, 1 mm or 1.5 mm. In the embodiment, the setting of the tensile force not higher than 0.2N prevents the glue line from being too difficult to loosen, resulting in the folded guide layer being unable to release the compression state, thereby affecting the bloodstain dilution effect and the bonding effect; at the same time, the appropriate setting of the glue line width also prevents it from being too easy to loosen, resulting in the product being loosened during transportation and movement, resulting in excessive thickness of the guide layer, affecting the menstrual blood from passing through the layer into the composite absorbent layer 300, or resulting in waste of manpower and material resources caused by product rework. Furthermore, the setting of the interval can provide protection for the packaging structure 240, preventing it from being exposed, thereby reducing the risk of being accidentally touched; the appropriate setting of the width can prevent the distance between the locking structure and the edge of the opening from being too long, thereby ensuring that the locking structure is not too difficult to be triggered and unlocked, so that its function can be performed normally, and at the same time, it also avoids the formation of wrinkles or eversion at the edge of the first expansion layer. That is, in this solution, the width of the glue line, the tensile strength of the glue line after it is wetted, and the interval are combined to ensure that the glue line can firmly adhere to the sub-layer of the liquid-conducting layer before it gets wet, thereby reducing the product turnover rate, saving production costs, and improving production efficiency. At the same time, its premature loosening will cause it to be too thick and affect the user's use; and the glue line can be easily loosened after it gets wet, thereby ensuring the bloodstain dilution effect and self-adhesive effect.

[0053] Preferably, the folded liquid-conducting layer 200 adopts a 120 mm wide fluffy cotton material, which is formed by three folds of 3D ES fiber and 12D ES fiber or hollow PET polyester fiber, or PBT / PET elastic fiber. The folded width is 35 to 45 mm, preferably 40 mm, the gram weight is 20 gsm to 35 gsm, the thickness is 0.1 to 0.3 mm, preferably 2 mm, and after three folds, it is 0.4 to 0.8 mm, preferably 0.6 mm.

[0054] It can be understood that the thickness of the folded liquid-conducting layer 200 in this embodiment is a relatively thin setting, and the gram weight is also a relatively light setting. If the tensile strength of the glue line is too high, for example, higher than 0.2N, the liquid needs to soak most of the folded liquid-conducting layer 200 or even enter the composite absorbent layer 300 before the compression state can be released. This will cause the blood stains on the composite absorbent layer 300 to not be blocked in time. Therefore, the scheme of this embodiment combines the tensile strength setting of the glue line not higher than 0.2N with the thickness and gram weight of the folded liquid-conducting layer 200, so that the folded liquid-conducting layer 200 can be quickly released from the compression state when it contacts the liquid under the ultra-thin and ultra-light setting, thereby ensuring the fading of the blood stains on the folded liquid-conducting layer 200 and the blocking of the blood stains on the composite absorbent layer 300.

[0055] Next, the third layer of the sanitary product of this embodiment will be described.

[0056] refer to Figure 5 The composite absorption layer 300 is the third layer, which is an ultra-thin absorption structure. The composite absorption layer 300 includes: wood pulp, SAP and wet-strength paper; the wood pulp and SAP are mixed to form an absorption core layer, and the wet-strength paper is used to wrap the absorption core layer. In order to enhance the absorption and drainage effect of menstrual blood, the composite absorption layer 300 is also wrapped with a coarse fiber cloth layer. Wood pulp has good water conductivity, and SAP is a highly absorbent resin with super strong water absorption and can quickly absorb a large amount of liquid. The absorption core layer formed by mixing wood pulp and SAP is not only ultra-thin but also can achieve strong absorption of menstrual blood, and quickly lock the menstrual blood. Its strong absorption capacity avoids the accumulation of large amount of menstrual blood and infiltration into the folded liquid-conducting layer 200 above it, further ensuring the dilution effect of blood stains, and at the same time preventing side leakage and rear leakage. The absorption effect can be further enhanced by wet-forcing the absorption core layer.

[0057] Preferably, the gram weight of the composite absorbent layer 300 is 300gsm to 500gsm, for example, 310gsm, 350gsm, 400gsm or 450gsm. The thickness of the composite absorbent layer 300 before absorbing liquid is 0.35 to 0.5mm, for example, 0.4mm; the maximum thickness after absorbing liquid is 10 to 20 times that before absorbing liquid, for example, 0.4mm before absorbing liquid and 6mm after absorbing liquid; the width of the composite absorbent layer 300 is 1.5 to 2 times that of the folded liquid guide layer 200, for example, 1.8 times. Appropriate gram weight setting allows the sanitary product to remain light and thin while ensuring water absorption. The thickness of the composite absorbent layer 300 before absorbing liquid is appropriately set to help the sanitary product maintain a thinner appearance as a whole. After absorbing liquid, the expanded thickness and width are appropriately increased so that it will not be too thin to affect the absorbency, nor will it affect the comfort of the user due to being too thick. At the same time, it prevents the excessive thickness from increasing the path of blood passing through the folded liquid-conducting layer 200, resulting in an increased probability of residue and hindering blood transfer. Therefore, combined with the long strip shape and width setting of the folded liquid-conducting layer 200, the folded liquid-conducting layer 200 is set to a narrow and long shape, while the composite absorbent layer 300 is wide and thin, shortening the liquid-conducting path of the folded liquid-conducting layer 200, ensuring that the blood can be absorbed by the composite absorbent layer 300, avoiding blood residue, and increasing the contact area with the user's body parts to improve comfort; and the composite absorbent layer 300 can have sufficient absorption capacity to ensure the locking effect on blood, and at the same time will not be too thick to affect comfort.

[0058] In this solution, the thickness or width of the composite absorbent layer 300 before and after absorbing liquid is coordinated with the thickness of the folded guide layer, forming a sanitary product that is ultra-thin before absorbing liquid, has super water-absorbing performance after absorbing liquid, and is light and thin.

[0059] Next, the fourth layer of the sanitary product of this embodiment will be described.

[0060] The bottom layer is the fourth layer. The bottom layer is a leakproof bottom layer, which is used to prevent liquid from leaking out from the bottom. Preferably, its material is a breathable film. More preferably, the bottom layer is a 15gsm PE bottom film, which contains about 25,000 breathable micropores to prevent stuffiness, enhance breathability, and thus improve comfort.

[0061] Next, the production process of the sanitary product of this embodiment is described.

[0062] Place the bottom layer, spray glue evenly on the bottom layer, then place the composite absorbent layer 300 on top of the glue spraying, and continue spraying glue, while folding the 120mm elastic fluffy cotton material into three pieces to form a folded liquid-conducting layer 200, apply a 1-2mm wide wet-strength glue to the first sub-layer 210 and the second sub-layer 220 at 1mm away from the edge, and then place them on the composite absorbent layer 300 that has just been sprayed with glue, and then cover the top layer 100, cut out the required shape of the sanitary napkin, and form a multi-layer structure. Fix the two side wings on the two sides of the aforementioned multi-layer structure, seal the edges of the multi-layer structure, and obtain the sanitary napkin body. Example 2

[0063] This embodiment provides a sanitary product for a healthy microenvironment, which is different from Example 1 in that: a light-colored composition is provided in the folded liquid-conducting layer 200; the light-colored composition includes: monounsaturated fatty acid inclusions, surfactants and carrier solvents; the mass ratio of the unsaturated fatty acid to the surfactant is (2.1-2.3):1, for example, 2.2:1 or 2.3:1. Specifically, the monounsaturated fatty acid inclusions are preferably safflower seed oil, grape seed oil or sunflower seed oil, etc., and the surfactant is preferably Surfynol 465 surfactant, specifically lauryl sulfate, lauryl amine oxide, coconut oil ester lauroyl sarcosinate, lauryl sulfosuccinate, etc. The carrier solvent is preferably water, and the amount of the carrier solvent added is determined according to actual needs.

[0064] The desalination composition is wrapped in microcapsules and then sprayed on the surface of the folded liquid-conducting layer and penetrates into the folded liquid-conducting layer. After spraying, the folded liquid-conducting layer is dried to allow the desalination composition to combine with the fibers in the folded liquid-conducting layer 200. The diameter of the microcapsules is generally 1-500 μm.

[0065] Menstrual blood is composed of blood, endometrial tissue fragments, cervical mucus, plasmin and other components. The color of menstrual blood comes mostly from hemoglobin in the blood; the light-colored composition can oxidize hemoglobin and turn it into a whitish yellow, thereby achieving the purpose of lightening menstrual blood. Through the light-colored composition and the structural setting of the folded liquid-conducting layer itself, both physical and chemical lightening are achieved, so that even when the amount of menstrual blood is large, the blood stains can still be effectively lightened, further optimizing the user experience.

[0066] The lightening composition is wrapped in microcapsules and sprayed, and both the surface and the interior are covered, so that the microcapsules can be evenly dispersed on the folded liquid-conducting layer, so that the menstrual blood distributed in various parts of the folded liquid-conducting layer can be fully lightened; after drying, the carrier solvent evaporates, and the effective lightening components are combined with the fibers in the folded liquid-conducting layer through a simple operation process, which is suitable for mass production; and the lightening material can be firmly combined with the folded liquid-conducting layer through spraying and drying, preventing it from falling during transportation and movement and affecting the lightening effect.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the present invention shall be included in the protection scope of the claims of the present invention.
