In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 and 2 are views showing a disposable sanitary napkin pouch 100 having a waterproof function according to an embodiment of the present invention. 1 and 2, a disposable sanitary napkin pouch 100 having a waterproof function includes an outer surface 110, a zipper part 120, an inner surface 130, a first pad receiving part 140a, and a second It may include a pad receiving portion 140 made of a pad receiving portion 140b.

In a state in which a zipper part 120 is provided in the disposable sanitary napkin pouch 100 having a waterproof function of the square of FIG. 1 and the handle 120a is coupled to the end of the zipper part 120, the zipper is made by using the handle 120a. When the part 120 is opened and opened, as shown in FIG. 2, an interior in which the first pad receiving part 140a and the second pad receiving part 140b divided around the center are formed may be formed.

Since the first pad receiving portion 140a and the second pad receiving portion 140b are formed to be symmetrical to each other, exposure to moisture is prevented for the disposable sanitary napkin before use, and water does not leak from the used disposable sanitary napkin. It can provide the effect of preventing odor.

On the other hand, the outer surface 110 and the inner surface 130 are formed of leather, fabric, etc., and it is preferable to use a waterproof treatment when using the fabric.

3 shows the number of first pads corresponding to A-A' in FIG. 2 after the disposable sanitary napkin pouch 100 having a waterproof function is opened using the zipper part 120 and the handle 120a as shown in FIG. Represents a cross-sectional structure showing the structure of the inner surface of the pad receiving unit 140u corresponding to the face of the payment (140a) and the second pad receiving unit (140b) that are opened and faced equally to the front when opened, and when closed and stored, It is a drawing. Referring to FIG. 3, the inner surface 140u of the pad receiving part may provide a waterproofing function and a filtering and breathable structure.

To this end, the inner surface 140u of the pad receiving part includes a pad contact surface 141, a first absorption and collection induction layer 142, a first filtering layer 143, a second filtering layer 144, and a breathable PE film layer ( 145), may include an outer skin layer 146.

The pad contacting surface 141 is a first absorption and collection induction layer 142 and a first filtering layer 143 sequentially between the inner surface 130 and the outer skin layer 146 positioned on the inner surface 130 or above the inner surface 130. ) And the second filtering layer 144, the first pad receiving portion 140a and the second pad receiving portion 140b may have surfaces in direct contact with the disposable sanitary napkin during storage.

More specifically, the pad contact surface 141 includes odor induction and filtering by the first absorption and collection induction layer 142, the first filtering layer 143 and the second filtering layer 144, and the breathable PE film layer 145. ) In order to improve breathability using the first pad receiving unit 140a and the second pad receiving unit 140b on the contact surface of the disposable sanitary napkin used for the post-use sanitary napkin that is primarily stored in a state of menstrual blood. It has a waterproof function and a PLA sheet to quickly move to the first filtering layer 143 through the first absorption and collection induction layer 142 while filtering the smell of the disposable sanitary napkin used through the inner ventilation hole 141a. It may be formed on the rear surface of the outer surface 110.

In other words, the PLA sheet can form a mixture of polyLactic Acid (PLA)-based raw materials and polyethylene, which is an eco-friendly recycled material. Here, the weight ratio of each raw material composition constituting the PLA (PolyLactic Acid)-based raw material can be performed in a manner requested by the orderer, and can also be produced based on other main raw materials.

Among PLA (PolyLactic Acid)-based raw materials, PLA is a thermoplastic polyester produced by polymerizing lactide or lactic acid obtained by fermenting plants such as renewable corn. It is not only irrelevant to fossil resource depletion, but can be easily decomposed by landfill after use. It has environmentally friendly characteristics. PLA can be prepared by polymerizing lactic acid or lactide, and if necessary, glycol compounds such as ethylene glycol or propylene glycol, dicarboxylic acids such as ethanedioic acid or terephthalic acid, glycolic acid or 2-hydroxy It may be copolymerized with an appropriate monomer such as hydroxycarboxylic acid such as benzoic acid or lactones such as caprolactone or propiolactone. And, PLA can be usually divided into D, L-PLA, meso-PLA, D-PLA, L-PLA, etc., but in the present invention is not limited to the type, the above-described PLA alone or two or more It can be mixed and used.

In addition, in another embodiment of the present invention, the pad contact surface 141 includes a resin composition consisting of 5 to 7 parts by weight of polyethylene based on 100 parts by weight of PLA (PolyLactic Acid) to reinforce the strength. By being formed in a method of coating at least one or more of them, compared to the case where the used disposable sanitary napkin is formed only with cotton material, the problem that menstrual blood may be adhered to the used disposable sanitary napkin is solved and the first absorption and collection induction layer 142 through the ventilation hole 111 quickly ) To move the smell.

Here, the ventilation hole 111 is located in the upper area of the pad contact surface 141 that is spaced apart from the area where the used disposable sanitary napkin is stored, and can prevent the menstrual blood from leaking out of the used disposable sanitary napkin, and quickly absorbs the first And it may serve as a passage through the collection induction layer 142 to allow air to flow out while the menstrual blood is absorbed.

In addition, in another embodiment of the present invention, ethylene vinyl acetate copolymer (EVA) 3 to 4 parts by weight, polyurethane 2 based on 5 to 7 parts by weight of polyethylene per 100 parts by weight of PLA (PolyLactic Acid) to reinforce strength A resin composition consisting of to 3 parts by weight can be used to coat the upper and lower surfaces of the pad contact surface 141, and the pad contact surface 141 made of PLA-based synthetic resin material manufactured by the above resin composition is eco-friendly recycling using only PLA. Compared to the material, it not only shows improved performance in tensile strength, flexural strength, load deformation temperature, and impact strength, but also lowers the manufacturing cost because the composition material itself is inexpensive.

The first absorption and collection induction layer 142 is formed of a fabric material such as clonal fabric, and is formed between the pad contact surface 141 and the first filtering layer 143, and has the same area as the cross section of the ventilation hole 111. It is formed and inserted into the center of the pad contact surface 141 with a ventilation hole 111 having a diameter corresponding to 1/50 to 4/50 of the total area of the pad contact surface 141 in the upper area of the pad contact surface 141 It may be formed to be, it may be formed in a replaceable type.

Accordingly, the first absorption and collection induction layer 142 not only serves to primarily absorb odors from the air provided through the ventilation holes 111 of the pad contact surface 141, but also the first filtering layer 143 And it may play a role of securing air permeability to the breathable PE film layer 145 through the second filtering layer 144.

To this end, the first absorption and collection induction layer 142 improves breathability and absorption rate through processing of the fabric material, and a coating layer of a polypropylene sheet may be formed on the upper and lower surfaces of the fabric material. Here, the polypropylene sheet is a polypropylene sheet having an excellent tensile strength by adding a weight ratio of 100: 2 to 5 to the entire mixture in which 8 to 13 weight ratio of carbon fibers is added to the polypropylene 87 to 92 weight ratio. Carbon fibers having excellent breaking strength may be added and mixed with propylene to obtain the required breaking strength as the first absorption and collection induction layer 142. Here, the air purifying material is activated carbon particles, in particular, containing or comprising activated carbon having reactive and/or catalytic enhancement, and the activated carbon is in the form of separated activated carbon particles, preferably in the form of spheres or granules, and the activated carbon is Zn, It is strengthened and imparted with a metallic component corresponding to one of Sn and Cu, and the metallic component may preferably comprise at least one metal-containing ionic liquid based on a metal compound, in particular containing metal ions. Here, the specific use of metal ions, preferably ionic liquids containing at least one metal compound, for enhancing activated carbon with a metallic component in order to provide activated carbon having reactive or catalytic properties, especially in metal-containing ionic liquids. It is possible to provide a method of strengthening the activated carbon with metallic components in the form of coating, wetting, and impregnation of activated carbon.

In particular, the surface structures of the activated carbon, including the pores, in particular micropores, mesopores or air pores, as well as the external as well as internal surface structures, are formed by at least partially contacting, wetting and impregnation with a metal-containing ionic liquid and a metallic component thereof, It can improve odor removal performance.

On the other hand, in the present invention, in order to form a film-type polypropylene sheet that is a material for the coating layer of the first absorption and collection induction layer 142, the extrusion melt is formed by extrusion using an extrusion device, where at a temperature of 230 to 270 °C. It is preferable to dissolve. Thereafter, when passing through the molten extrusion melt, a film-type polypropylene sheet is formed in a T-die method, and a cooling device attached to the outlet of the die cools the film-type polypropylene sheet. Upon cooling, the film-type polypropylene sheet is cooled, and then transferred to a guide roller for cooling. The cooling device used here may control the temperature of the film-type polypropylene sheet in a preset temperature range using a Peltier element, a temperature sensor, and an Arduino substrate. Here, the temperature setting range is in the range of 7°C to 15°C in consideration of the temperature difference immediately after production of the film-type polypropylene sheet using the cooling by the guide roller corresponding to the room temperature and the T-die method by the die for the extrusion melt It is desirable to set. Thereafter, the film-type polypropylene sheet cooled by the guide roller is guided to the stretching device, and the film-type polypropylene sheet is transferred to the stretching device by the guide roller, while the total length of the guide roller is set. It is possible to provide a thermal stabilization process at room temperature. The stretching apparatus performs stretching by pressing and pulling a film-type polypropylene sheet passing through a guide roller into a thin film. More specifically, the area ratio before and after stretching for the final product, the polypropylene film, increases by 1 to 2: 2.8 to 3.6 times by performing stretching in the transverse direction under heating and pressing the film-type polypropylene sheet during stretching. Do it. Here, the heating temperature during stretching is 250 to 350 °C, the pressurized state is in a state of 330 to 430 mbar, and when the thickness of the coating layer corresponding to the polypropylene film is 2700 μm, it is preferably performed at 260 °C and 370 mbar. .

Meanwhile, the heating temperature within the above-described preferable temperature range during stretching should be performed at 250 to 350°C. If the temperature is higher than the temperature range, the degree of freedom of the molecules increases, and the orientation of the molecules is difficult. In addition, when the temperature is lower than the temperature range, stretching is difficult and the polypropylene sheet is not stretched and is broken.

Meanwhile, a uniform lattice structure (mesh structure) having a diamond-shaped structure, a net shape, and a square shape can be formed according to the mesh process along with softening of the polypropylene sheet between the heat stabilization process after stretching the polypropylene sheet. . By forming such a mesh structure, it is possible to increase the air permeability, the absorption rate of menstrual blood and the aggregation rate of the inner fabric material.

The first filtering layer 143 and the second filtering layer 144 are formed between the pad contact surface 141 and the breathable PE film layer 145 to be 3.2 to 3.5 larger than the width of the first absorption and collection induction layer 142, , The height can be formed the same.

Here, the material and manufacturing method of the first filtering layer 143 and the second filtering layer 144 are the same as the coating layer of the first absorption and collection induction layer 142, but the first filtering layer 143 and the second filtering layer ( After stacking the polypropylene sheets in layers to form the core region of 144), the entire process, like the manufacturing process of foamed foam, is a foaming step of inflating and foaming the injected synthetic resin particles, and removing moisture contained in the foamed particles. It can be formed through a drying step and a molding step of supplying high-temperature steam to the dried expanded particles so that the expanded particles are entangled and bonded to each other.

That is, the generated first filtering layer 143 and the second filtering layer 144 are formed by being coated on the front and rear surfaces of the core of the central region, respectively, made of ultrafine fibers, so that the first filtering layer 143 and the second filtering layer 143 The breathability of the filtering layer 144 and the menstrual blood flowing through the internal microfibers can be absorbed, and a plurality of mesh-structured polypropylene sheets are laminated to reduce the weight in a foamed form.

The breathable PE film layer 145 may be formed by coating a breathable PE film on the nanofibers on the upper surface and formed in the same shape as the pad contact surface 141 to contact the second filtering layer 144.

That is, in the nanofibers used in the present invention, the elastic nanofibers are prepared by dissolving an elastic polymer having fiber-forming ability and a material containing silver (Ag) ions in an organic solvent to prepare an electrospinning solution, and then electrospinning the electrospinning solution. It can be used to prepare an elastic nanofiber web (nanofiber web) containing the reduced silver nanoparticles.

Here, a composite composition produced by mixing talc and a slip agent in a mixture of polyurethane (Thermalplastic Poly Urethan, TPU) as a raw material used for the coating layer of the breathable PE film layer 145 It can be fed to the extrusion device using a hopper.

Here, in addition to polyethylene as a raw material, TPU is a rubbery elastic body having a urethane group (-NHCOO-), and has excellent properties in terms of mechanical strength, abrasion resistance, colorability, and texture, so the resin produced using it is not only suitable for coating compositions, etc. In addition, it may play a role of limiting the passage of menstrual blood by controlling the weight to be mixed with polyethylene. In addition, TPU is a non-PVC-based thermoplastic resin, which is harmless to humans because there is no risk of generating harmful compounds, and is environmentally friendly because it does not emit air or soil pollutants when incinerated.

In one embodiment of the present invention, TPU can be obtained by synthesizing 4,4'-methylenediphenyl diisocyanate, polybutyl adipatediol, and 1,4-butanediol, and 4,4'-methylenediphenyl diisocyanate 15 to 17 parts by weight of 1,4-butanediol and 20 to 30 parts by weight of polybutyl adipatediol may be synthesized based on 100 parts by weight. Here, the weight ratio of 4,4'-methylenediphenyl diisocyanate, polybutyl adipatediol, and 1,4-butanediol can be appropriately changed depending on the physical properties to be obtained and the use of the thin-film urethane film. For example, when the weight ratio of 4,4'-methylenediphenyl diisocyanate is increased, the ratio of the hard segment in the polyurethane is increased, so that the overall hardness and the like are increased. Conversely, poly4,4'-methylenediphenyl diisocyanate When the weight ratio of isocyanate becomes small, the proportion of soft segments in the polyurethane increases, thereby increasing elongation and ductility.

Talc is added to improve the stretching (molding) and hydrolysis resistance of the composite composition for preparing the coating layer composition of the breathable PE film layer 145. Polyurethane is added in a weight ratio of 12 to 11: 1 to 3 10 to 17 parts by weight may be used based on the total 100 parts by weight of the mixed mixture. Here, when the weight ratio of polyethylene is less than 12, when the weight ratio of polyethylene is 11, the air permeability decreases by 20 to 35% compared to the case where the weight ratio is 12. Conversely, when the weight ratio of polyethylene exceeds 17, the weight ratio of polyethylene is 18. In this case, there is a problem that the transmittance of menstrual blood is increased by 10 to 13% compared to the case where the weight ratio is 17. That is, in the present invention, a PE film with nanofibers applied to a sanitary napkin according to the weight ratio of polyethylene and polyurethane is applied to the sanitary napkin to lower the liquid permeability and increase the breathability, so that less irritation to the skin and a safe, breathable sanitary napkin can be provided.

Here, when the amount of talc is less than 10 parts by weight, the effect of improving the dimensional stability when forming the coated sheet by melting and stretching the mixture is inferior, and when it exceeds 17 parts by weight, the mechanical strength and abrasion resistance are significantly deteriorated.

The slip agent allows the coating sheet for the breathable PE film layer 145 formed in two layers to enter the tension device to be easily slid and divided, and a coating sheet for the thin film breathable PE film layer 145 by a winding device. It can be prevented from sticking together when winding. The slip agent used in the present invention is a first type slip agent, and is preferably 0.5 to 0.7 parts by weight based on 100 parts by weight of the mixture of the amide slip agent.

Here, when the amount of the slip agent is less than 0.5 parts by weight, the coefficient of friction is not sufficiently lowered, and when the amount exceeds 0.7 parts by weight, the winding rate may decrease. As amide slip agents, unsaturated 13-cis-docosenamide (hereinafter referred to as erucamide), 9-cis-octadecenamide (hereinafter referred to as oleamide) ) And saturated octadecanamide (octadecanamide: steamide (stearamide)), docosanamide (docosanamide: behenamide (behenamide)), but it is more preferable to use an unsaturated system.

The second type of slip agent of the present invention is montan wax, a rubber-based elastomer, specifically, styrene butadiene strin block copolymer (SBS), styrene ethylene/butylene resin (SEBS), inorganic (specifically, , Silica, talc, calcium carbonate) is preferably used alone or in combination of one or more. Here, the second type slip agent is preferably 0.5 to 0.9 parts by weight based on 100 parts by weight of the mixture.

That is, if the second type slip agent is less than 0.5 parts by weight, the coefficient of friction is not sufficiently lowered, and if it exceeds 0.9 parts by weight, the winding rate may decrease.

Thereafter, the extrusion device extrudes the mixture in a molten state to create a PE extruded melt.When the PE extruded melt is created using the mixture, the weight average molecular weight of the mixture is 500,000 g/mol or more, and the melt index is 0.5 to 30 g/5 minutes. It is preferably (250°C), in addition, it is preferable that the molecular weight distribution (PI) is 6 or more, and the melt strength is 70 mN or more.

On the other hand, in another embodiment of the present invention, when stretching is additionally performed on the coating sheet for the breathable PE film layer 145, the breathable PE film layer using the tension provided by the multiple transfer rollers between the heat stabilization process after stretching ( A diamond lattice structure can be obtained according to a mesh process using a needle split method along with softening of the coating sheet for 145). Here, the needle split method allows the coating sheet for the breathable PE film layer 145 to pass upward of the needle split roller formed by the grid-shaped needle along the outer circumferential surface, and at this time, the needle split roller is at the entry end for entering the multi-feed roller. Is formed. Accordingly, diamond lattice formation for the coating sheet for the breathable PE film layer 145 stretched while a tension pulling tension is applied to the plurality of transfer rollers for the coating sheet for the breathable PE film layer 145 coming out of the stretching oven The mesh process is performed by rotation of the needle split roller rotated for the purpose, thereby forming a regular and uniform diamond grating structure using tension and timing according to rotation. At this time, by using the above-described tension, the needle split roller may perform drag type punching using a grid-shaped needle on the outer circumferential surface.

The breathable PE film layer 145 manufactured in this way not only performs a waterproof function against moisture, but also has breathability as a whole, and thus performs a function of dispersing and collecting residual odors provided by the second filtering layer 144. I can. Here, the first filtering layer 143 and the second filtering layer 144 inside the breathable PE film pack 145 may be formed in a replaceable type.

The outer skin layer 146 corresponds to the inner surfaces of the first pad receiving portion 140a and the second pad receiving portion 140b, and the material is formed of leather, fabric, etc., the same as the inner surface 130, and utilizes fabric. It is advisable to utilize the waterproof treatment.

In addition, the adhesive method with the breathable PE film layer 145 is a method of bonding by pressing and moving through a roller using a breathable PE film layer 145 and an adhesive solution, and the outer skin layer 146 and the breathable PE film layer 145 The adhesion can be improved through an embossed structure on the edge.

In addition, the material of the outer skin layer 146 is made of a waterproof material on the upper surface, and the lower surface may be formed of two layers of an outer skin of a seasonal material such as leather, hemp material, cotton, and microfiber fabric described above, and the pad contact surface ( When adhering to the pad contact surface 141, an outer ventilation hole corresponding to the same size is formed at the same height as the inner ventilation hole 141a of the pad contact surface 141, and an additional second absorption and collection induction layer 146a is formed to fill the outer ventilation hole. By this formation, the same function as the first absorption and collection induction layer 142 described above in the final stage can be performed.

The pad contact surface 141 is sequentially formed between the inner surface 130 and the outer skin layer 146 positioned on the inner surface 130 or the first absorption and collection induction layer 142, the first filtering layer ( In order to form the 143) and the second filtering layer 144, the first pad receiving portion 140a and the second pad receiving portion 140b form a surface in direct contact with the disposable sanitary napkin during storage, and 1 The number of first pads to induce and filter odors by the absorption and collection induction layer 142, the first filtering layer 143 and the second filtering layer 144, and to improve breathability using the breathable PE film layer 145 It is located on the contact surface of the disposable sanitary napkin used on the payment (140a) and the second pad receiving part (140b), and has a waterproof function for the sanitary napkin after use, which is primarily stored in a state of menstrual blood, and an inner ventilation hole (141a). It is formed on the back of the outer surface 110 as a PLA sheet to quickly move to the first filtering layer 143 through the first absorption and collection induction layer 142 while filtering the smell of the disposable sanitary napkin used through, In order to reinforce the strength with PLA sheet, it is formed by coating a resin composition consisting of 5 to 7 parts by weight of polyethylene per 100 parts by weight of PLA (PolyLactic Acid) on at least one of the upper and lower surfaces of the nonwoven fabric sheet to allow internal ventilation. It serves to move the odor to the first absorption and collection induction layer 142 through the hole (141a),
The first absorption and collection induction layer 142,
It is formed between the pad contact surface 141 and the first filtering layer 143, has the same area as the cross section of the inner ventilation hole 141a, and covers the entire pad contact surface 141 in the upper area of the pad contact surface 141 It is formed in a replaceable type so as to be inserted into the center of the pad contact surface 141 with the inner ventilation hole 141a having a diameter corresponding to 1/50 to 4/50 in the area, and the inner ventilation hole of the pad contact surface 141 ( Not only plays a role of primarily absorbing odors from the air provided as 141a), but also secures breathability to the breathable PE film layer 145 through the first filtering layer 143 and the second filtering layer 144 It plays a role and forms a coating layer of polypropylene sheet on the upper and lower surfaces of the fabric material in order to improve breathability and water absorption through processing of the fabric material, but the polypropylene sheet is carbon fiber 8 to the weight ratio of polypropylene 87 to 92 To 100 parts by weight of the mixture added with a weight ratio of 13 to 13, the weight ratio of the air purifying material was added in a ratio of 100: 2 to 5, and then carbon fibers having excellent breaking strength were added and mixed with polypropylene having excellent tensile strength. The collection induction layer 142 has the required breaking strength, and the air purifying material contains or contains or consists of activated carbon having reactive or catalytic reinforcement as activated carbon particles, and the activated carbon is in the form of separated activated carbon particles, and Zn , Sn, and at least one metal-containing ionic liquid containing a metal ion based on a metal compound strengthened with a metallic component corresponding to one of Cu,
The first filtering layer 143 and the second filtering layer 144,
Between the pad contact surface 141 and the breathable PE film layer 145, it is formed to be 3.2 to 3.5 larger than the width of the first absorption and collection induction layer 142, the height is the same, and the first filtering layer 143 and the first 2 After stacking the polypropylene sheets in layers to form the core region of the filtering layer 144, the entire process includes a foaming step of inflating and foaming the injected synthetic resin particles, a drying step of removing moisture contained in the foamed particles, and , It is formed through a molding step in which the expanded particles are entangled and bonded to each other by supplying high temperature steam to the dried expanded particles,
The breathable PE film layer 145 is composed of a nanofiber coated with a breathable PE film on the upper surface, and formed in the same shape as the pad contact surface 141 to come into contact with the second filtering layer 144,
The outer skin layer 146 corresponds to the inner surfaces of the first pad receiving portion 140a and the second pad receiving portion 140b, and the material is formed of the same material as the inner surface 130, and the breathable PE film layer 145 ) Is a method of bonding by pressing and moving through a roller using a breathable PE film layer 145 and an adhesive solution, and adhesion through an embossing structure on the edge of the outer skin layer 146 and the breathable PE film layer 145 It has a structure that improves, and an outer vent hole corresponding to the same size is formed at the same height as the inner vent hole 141a of the pad contact surface 141 and fills the outer vent hole with an additional second absorption and collection induction layer ( Disposable sanitary napkin pouch having a waterproof function, characterized in that 146a) is formed. delete delete
