Description

Functional smart sanitary napkins with phytoncide}

The present invention relates to a sanitary napkin containing sustained phytoncide so that the characteristics such as antibacterial and deodorant possessed by phytoncide can be continuously maintained, and more specifically, an existing disposable sanitary napkin using phytoncide's antibacterial properties and physiological activity. It relates to a new sanitary napkin having a sanitary antimicrobial function that is beneficial to health and suppresses the occurrence of dermatitis such as menstrual blood odor, itchiness, itching, rash, etc.

The sanitary napkin is one of the women's essential products for women to receive menstrual blood or efficiently absorb and absorb secretions such as cold. Conventional conventional sanitary napkins are made by stacking several layers of pure cotton fabrics, so that when used, physiological blood is discharged to the outside. Disposable sanitary napkins are developed to overcome the inconveniences and disadvantages of these conventional sanitary napkins. Typically, the structure of the disposable sanitary napkin is a top sheet having wings on both sides and contacting the vulva side of a woman, an absorption layer absorbing menstrual blood discharged in contact with the lower side of the top sheet, and the menstrual blood absorbed by the absorption layer is discharged to the outside through the lower side. It consists of a lower water-proof sheet that blocks it. As such, today, disposable sanitary napkins have been developed and evolved, and raw materials and functions are diversified, and various kinds of fragrances are added, and so many kinds of products have been released and sold. However, the disposable sanitary napkin has a fatal disadvantage that causes various female diseases such as dermatitis and allergies due to its manufacturing process and various chemicals used in products.

Many women suffer from menstrual blood odor, vaginitis and itching, rash, and soreness while wearing disposable sanitary napkins. In severe cases, these discomforts also cause psychological stress. Such sequelae is caused by contact with a substance causing contact dermatitis by a sanitary napkin, and the use of an emulsifier to make the sheet softer is the cause.

In general, the disposable sanitary napkin is made of rayon fiber or polyethylene film, and the absorbent layer is made of absorbent paper or polymer absorber, and the bottom waterproof sheet is made of polyethylene film or polypropylene film.

Polyethylene used in the top and bottom sheets is widely used in household goods such as ice cream containers and paper cup coatings, and releases environmental hormones at high temperatures. It is known that when environmental hormones enter the body, they accumulate without excretion, causing endocrine disruption and causing dementia and diabetes.

The polymer absorber used in the absorbent layer that absorbs menstrual blood rapidly is called a superabsorbent resin and is made of acrylic, polyvinyl, and alcohol as raw materials. Ingredients include chemicals such as sodium polyacrylate, nonionic anionic surfactants, oxidizing agents, synthetic polymers, dextrins and fatty acid esters. Widely used in diapers, sanitary napkins, and industrial products, sodium polyacrylate can absorb hundreds to thousands of times more moisture than its own volume.

The sanitary napkin is treated with a kind of bleach called fluorescence brightener to make it look white. The use of disposable sanitary napkins causes the smell of menstrual blood to be severe, and the polymer chemical absorber and the bacteria in menstrual blood cause a chemical reaction, which makes the smell worse. In order to compensate for this, herbal sanitary napkins or herbal sanitary napkins are available on the market, but because of the scent components produced by themselves, it reduces the discomfort from menstrual blood, but its efficacy is no different from that of normal sanitary napkins. Rather, it mixes with chemicals to create a unique odor.

Due to this case, the cotton sanitary napkin came out, but there is no irritation to the skin and the smell of secretion is deodorized, but there is no discomfort, but the surface absorption rate is better than the disposable sanitary napkin, and the menstrual blood leaks to the side, making the activity uncomfortable. There was a problem causing.

As a method of solving the above problems of the disposable sanitary napkin, attempts have been made to develop a disposable sanitary napkin using natural materials having physiological activity and using various natural materials. One of the representative bioactive substances among various natural substances is phytoncide.

Phytoncide refers to a bioactive material that has antibacterial properties that trees radiate in the air to protect themselves from pests and microorganisms. Phytoncide itself has a unique directionality, and various physiologically active functions such as deodorization and deodorization, stress relief, soothing and comfort, antibacterial action, immune function enhancement, cardiopulmonary function strengthening, vascular function strengthening, respiratory strengthening and skin sterilization action It is a natural substance that has been proven to have excellent effects on atopy, sick house syndrome, acne, and asthma. Therefore, if the proven performance and efficacy of phytoncide can be applied to a disposable sanitary napkin, the possibility of solving the problem of the disposable sanitary napkin can be expected. In fact, many attempts have been made to apply the efficacy of phytoncide to disposable sanitary napkins.

Korean Patent Registration No. 10-1184480 impregnates the leaves and stems of cypress trees and immersed them in the dried cypress leaves and stems to create an antimicrobial sanitary napkin that emits phytoncide. The phytoncide has strong volatility and remains in the sanitary napkin for a long time. Naturally, even if it is stored for a short period of time, all phytoncide volatilizes, so it is impossible to see the effect of phytoncide when used in real life.

Another conventional patent publication No. 10-2015-0089352 is characterized in that the absorbent layer contains a phytoncide component, but there is no information on how to contain it, and it is said to contain only a component. Even technology or ideas are not identified.

Another conventional Patent Publication No. 10-2016-0066322 extracts phytoncide from a cypress tree and dries it in fibers and then dries it, and the components of phytoncide having volatility are blown away, so that the effect of phytoncide is not seen when used.

Therefore, although phytoncide has various effects, it is difficult to expect phytoncide efficacy when using disposable sanitary napkins because phytoncide is rapidly volatilized from the sanitary napkin due to the rapid volatility of phytoncide during storage or use. In addition, the existing prior art and patents have not been proposed a specific method for the extraction method of phytoncide to be applied to sanitary napkins, and commercial production such as using the plant itself, such as the leaves or stems of cypress trees containing phytoncide, in the absorber. It is more difficult to expect the efficacy of phytoncide, which is a difficult method to apply to.

Accordingly, the present invention relates to a sanitary napkin containing phytoncide and a method of manufacturing the phytoncide, in which the efficacy of phytoncide can be continuously expressed for a long time. More specifically, after extracting the phytoncide component from a tree containing phytoncide, and inhibiting the high volatility of the extracted phytoncide component to release the phytoncide so as to sustain the efficacy and properties of phytoncide for a long time, the sustained phytoncide is By containing it in a disposable sanitary napkin, the characteristics and efficacy of phytoncide have deodorizing and deodorizing action, stress relief, soothing and pleasant action, antibacterial action, immune function improvement, cardiopulmonary function strengthening, vascular function strengthening, respiratory strengthening and skin sterilizing action, etc. In order to suppress the occurrence of dermatitis, such as menstrual blood odor, itching, rash, rash, which is a disadvantage of the existing disposable sanitary napkin, and furthermore, it is intended to provide a new composition of a sanitary napkin having a beneficial and hygienic antimicrobial function and a method for manufacturing the same.

(1) Lee Cheol-tae, Journal of the Korean Industrial Chemistry Society, Industrial Chemistry, 26(6), 648-658(2016).

The present invention is to propose a method of manufacturing a new sanitary napkin and a method of manufacturing the same, which suppresses the occurrence of dermatitis such as menstrual odor, itchiness, itching, and rash, which are various problems of the conventional disposable sanitary napkin. do. More specifically, the present invention is the effect of phytoncide, stress relief, soothing and pleasant action, antibacterial action, immune function enhancement, cardiopulmonary function strengthening, vascular function strengthening, respiratory strengthening and skin sterilization action, deodorization and deodorization effect and its action is disposable It is to propose a method for sustaining the release of phytoncide so that it can be expressed when using a sanitary napkin, and to provide a functional sanitary napkin containing a sustained-release phytoncide that can be applied to users of sanitary napkins and a method for manufacturing the same.

The present invention, in order to achieve the above object, in a disposable sanitary napkin including a top sheet, an absorbent layer, and a waterproof layer, a disposable sanitary napkin containing sustained release phytoncide, characterized in that the sustained phytoncide component is impregnated in the top sheet or absorbent layer. Provides

A non-woven fabric or film containing phytoncide in the form of sustained release of phytoncide is installed between the topsheet and the absorbent layer, or it is granulated to be contained in the absorbent layer, or the phytoncide, which is sustained release instead of film or granulation, is directly topsheet or sanitary napkin. It is prepared by coating on the inner surface of the.

A way to suppress the high volatility of phytoncide is to confine the components constituting phytoncide in a polymer network or a mesh so as to be emitted through the mesh. To this end, in the present invention, a suitable amount within the range of 0.01 to 40 parts by weight of phytoncide essence extracted from a tree containing phytoncide in PVA 1.5 to 70 parts by weight and glycerine 2.0 to 50 parts by weight to form a mesh composed of a polymer material , It is made by adding 10 to 95 parts by weight of aqueous phytoncide aqueous solution (mixed with water if there is no aqueous phytoncide aqueous solution), and 0.1 to 20 weight of cellulose to further enhance the sustained-release properties if necessary. Part, 0.1 to 20 parts by weight of boride may be additionally added as a curing agent. The sustained-release phytoncide designed in the present invention has a difference in the degree to which phytoncide is contained in such a polymer mesh, and the phytoncide components contained in the polymer mesh are divergent depending on the degree of curing of the mesh, but gradually diverge, and after wearing the disposable sanitary napkin The menstrual blood is absorbed by the sanitary napkin, and at the same time, the polymer network is decomposed by the moisture in the menstrual blood, thereby acting as a mechanism in which the phytoncide component is rapidly released.

The sustained-release phytoncide thus prepared may be introduced into a disposable sanitary napkin in various ways depending on the use and characteristics. That is, the sustained phytoncide can be produced as a thin film as it is, and when sprayed, it can be coated at a desired location or site. The manufactured thin film type film can be introduced into a disposable sanitary napkin in an appropriate size or shape, and when coated on a nonwoven fabric and dried, the nonwoven fabric can be introduced into a disposable sanitary napkin. The sustained-release phytoncide introduced in various ways gradually dissipates the phytoncide component when used, thereby suppressing the occurrence of physiological odor, itchiness, itching, rash, and dermatitis, which are problems of disposable sanitary napkins according to the physiological activity according to the essential properties of phytoncide. It will be a smart sanitary napkin with beneficial and hygienic antimicrobial functions for health that can prevent bacterial infections that may occur in the city in advance.

The present invention provides stress relief, soothing and pleasant action, antibacterial effect, immune function improvement, cardiopulmonary function strengthening, vascular strengthening, respiratory and skin sterilization, deodorizing and deodorizing effect, and its physiologically active effect on disposable sanitary napkins. By applying, it is intended to manufacture a functional smart sanitary napkin of a new configuration that can suppress the occurrence of dermatitis such as menstrual blood odor, itching, rash, rash, which is a problem of disposable sanitary napkin.

The present invention, which releases phytoncide having excellent physiological activity and applies it to the sanitary napkin, does not sensitively act on the skin because it is in a sustained state, and is also effective in preventing vaginitis in women due to the essential antibacterial properties of phytoncide. It is clean and hygienic by suppressing or eliminating the unpleasant odor of the skin, so it is effective for health even when it is worn outside the menstrual period for quality health.

In addition, the antimicrobial properties of these phytoncide inhibit the sterilization and reproduction of mites, fungi, and bacteria, and it is also possible to obtain anti-inflammatory and anti-allergic effects, thereby preventing itching and wheezing, and skin soothing effects. Therefore, the effect of the present invention is not limited to disposable sanitary napkins, and can be applied to various products directly contacted by the human body. First of all, if it is applied to a feminine panty liner which is a convenient form of a disposable sanitary napkin, it will be very effective in solving all kinds of discomforts or problems caused by the physiological phenomenon of women.

In addition, vaginitis is a common disease in women, such as a cold. The inside of the vagina maintains a certain acidity by derder line bacillus, thereby making the vagina self-cleaning. However, when the acidity is lowered for some reason, the self-cleaning action of the vagina decreases, so the resistance to invasion of bacteria may decrease. Vaginitis is caused by certain bacteria such as gonorrhea, trichomonas, and candida, and is also caused by E. coli. In addition, even in the case of a systemic disease, white blood cells or various germs may multiply in the vagina. Rarely, inflammation may be caused by an unknown cause. Therefore, prevention of vaginitis is more effective than treatment. This sustained phytoncide can be expected to be effective as a functional sanitary napkin, especially for women with severe vaginitis, by putting various medicines such as various types of vaginal treatments, antibiotics, and iodine, which are effective in treating vaginitis.

In addition, even when applied to diapers for children or infants and diapers for the elderly, it is possible to manufacture diapers for children and infants or diapers for the elderly with functionality that can expect the various effects described above. In addition, the technology of the present invention can be applied to a patient pad using the deodorizing and deodorizing functions of phytoncide. When a patient pad is used, the amount of curing agent may be increased to form a film in which mechanical properties are maintained.

It is also applicable to pet pads. In particular, in the case of pets kept indoors, severe odor may be generated if the pad is not replaced frequently by defecation, but in the case of a pad treated with sustained-release phytoncide as devised in the present invention, it is effective in suppressing the occurrence of odor and has a small amount In the urine, the discomfort that needs to be changed every time will be reduced.

Hereinafter, the present invention will be described in more detail as follows.

The present invention is a disposable sanitary napkin for stress relief, soothing and pleasant action, antibacterial effect, immune function improvement, cardiopulmonary function strengthening, vascular function strengthening, respiratory strengthening and skin sterilizing action, deodorizing and deodorizing effect and its physiological activity, which are essential effects of phytoncide. It is intended to manufacture a sanitary napkin of a new configuration that can be applied to and suppresses the occurrence of dermatitis such as menstrual blood odor, itch, itching, and rash, which are problems of the disposable sanitary napkin. That is, if the natural physiologically active substance called phytoncide is supported on a disposable sanitary napkin and the essential physiological activity and antibacterial properties of phytoncide can be expressed, problems with the existing disposable sanitary napkin can be solved.

For the same purpose, Korean Patent Registration No. 10-1184480 has attempted to introduce phytoncide-containing trees, such as the mouths and branches of trees containing phytoncide, into disposable sanitary napkins, and Korean Patent Publication No. 10-2016-0089352 contains phytoncide. It is not known how it is from the tree, and it has been suggested that the phytoncide is simply contained in the absorbent layer of the disposable sanitary napkin without any explanation of the extracted phytoncide itself. In addition, Korean Patent Publication No. 10-2016 0066322 claims to impregnate a phytoncide component into a disposable sanitary napkin, but suggests that the impregnated phytoncide be contained in cypress itself.

However, phytoncide has excellent antimicrobial properties and physiologically active properties that are beneficial to the human body, but phytoncide itself does not have a great effect, and phytoncide extracted from trees containing phytoncide should be at the level of essence. The effect of phytoncide biophysical activity can be expected. In addition, phytoncide essence, which effectively expresses excellent antibacterial and bioactive properties, is highly volatile and easily diffuses, so it is difficult to remain or exist continuously in the desired area or region, and eventually phytoncide's unique function is used. You will not be able to.

Therefore, the heat chain of the solution that can achieve the object of the present invention is to produce a sustained-release phytoncide that can suppress the high volatility of phytoncide essences against phytoncide essences extracted from trees containing phytoncide, and this sustained-release phytoncide The essence is contained in various ways in a disposable sanitary napkin, and when using the sanitary napkin, the antibacterial properties and physiological activity of phytoncide can be expressed.

The method to suppress the high volatility of phytoncide essence is to apply the principle that the components constituting phytoncide are trapped in a polymer network or a mesh, and the components of the phytoncide are released through the mesh. To this end, in the present invention, phytoncide essence extracted from a tree containing phytoncide in the range of PVA 1.5 to 70 parts by weight, glycerin 2.0 to 50 parts by weight to form a mesh composed of a polymer material, 0.01 to 40 parts by weight and aqueous solution of phytoncide 10 to 95 It is made by adding and mixing an appropriate amount capable of expressing physiologically active effects in the range of parts by weight (if there is no aqueous solution of phytoncide in water), the typical composition is as follows by weight parts of each component.

Polyvinylalcohol (PVA) 1.5 to 70.0 parts by weight

glycerin 2.0 ~ 50.0 parts by weight

Phytoncide Essence 0.01 ~ 40.0 parts by weight

Phytoncide aqueous solution (or water) 10 to 95 parts by weight

If the PVA amount is lower than 1.5 parts by weight of the total amount of the material, the molecular mesh cannot secure the phytoncide and maintain the required concentration, and when the PVA amount occupies 70 parts by weight or more, the elasticity is lowered, thereby reducing the antibacterial effect. As a result of analysis, phytoncide aqueous solution contains various physiologically active ingredients, which is very effective in expressing the desired efficacy in the present invention. However, depending on the type of extraction method for phytoncide essence, water may not be obtained since phytoncide aqueous solution of this water phase may not be obtained. That is, in order to manufacture the desired functional smart sanitary napkin, it can be obtained by adding phytoncide essence.

When the amount of glycerin is contained by 50 parts by weight or more, the mechanization properties are deteriorated, so that the destruction of the sustained phytoncide, that is, the molecular network containing phytoncide proceeds rapidly, and when the content of glycerin is lower than 2.0 parts by weight, the required elasticity cannot be secured, resulting in phytoncide It is not possible to secure the mechanization properties of the molecular net containing.

It is not necessary, but it is characterized in that 0.1 to 20 parts by weight of cellulose and 0.1 to 20 parts by weight of curing agent are included in cellulose, which can additionally enhance the sustained-release efficacy according to the desired direction and conditions. In the case, the composition of each component is as follows in parts by weight.

Polyvinylalcohol (PVA) 1.5 to 70.0 parts by weight

glycerin 2.0 ~ 50.0 parts by weight

Phytoncide Essence 0.01 ~ 40.0 parts by weight

Phytoncide aqueous solution (or water) 10 to 95 parts by weight

Cellulose 0.1 ~ 20.0 parts by weight

Hardener 0.1 ~ 20.0 parts by weight

In the proposed prescription

Cellulose is not necessary for sustained release of phytoncide, but it can add a sustained release effect and can itself increase antibacterial activity. In addition, it has the property of inhibiting the flow of the water phase components, which may contribute to preventing the leakage of menstrual blood from the disposable sanitary napkin. As the cellulose that can be used, carboxy methyl cellulose (CMC), Hydroxymethylcellurose (HPMC), methyl cellulose, and the like can be used. Cellulose is not particularly limited in whichever it is used, and the addition amount is appropriately 0.1 to 20.0 parts by weight. If the amount added is less than 0.1 part by weight, it is difficult to develop an effect to increase the persistence of phytoncide, and when used in more than 20 parts by weight, the viscosity is too high, so it is not easy when the sustained phytoncide is coated in a disposable sanitary napkin.

Hardeners are also not necessary for sustained release of phytoncide, but sustained phytoncide is contained in disposable sanitary napkins and is very effective in increasing the storage and storage of phytoncide components during the long-term distribution period after production of the product. In particular, when the sustained phytoncide is supported on a disposable sanitary napkin in the form of a film, it is more effective to increase the mechanical robustness and long-term storage of the film. Therefore, it is appropriate to add such a curing agent in an amount of 0.1 to 20.0 parts by weight. If the addition amount of H ₃ BO ₃ as a curing agent is less than 0.1 parts by weight, the mechanical robustness required for the film cannot be secured. However, when the amount is added in an amount of 20 parts by weight or more, the mechanical robustness of the sustained phytoncide is excessively increased, and thus, the emission of phytoncide can be relatively suppressed, and phytoncide components are not released even after inhalation of menstrual blood. It is not suitable because the antibacterial properties cannot be developed. In the present invention, as the curing agent, boron compounds such as boric acid (H ₃ BO ₃ ), Na ₂ B ₄ O ₇ can be effectively used, but other components are not limited or limited.

The content of phytoncide essence can be arbitrarily adjusted according to the physiological activity and antibacterial effect that the problem of the disposable sanitary napkin can be solved, and can be adjusted according to the type of carrying the sustained phytoncide on the disposable sanitary napkin. That is, the amount of the phytoncide essence contained may be arbitrarily adjusted according to a method of coating the coating by making the sustained phytoncide in a liquid form or by introducing the sustained phytoncide into a film or a particle. However, in the present invention, the sustained release of phytoncide is a method of containing phytoncide components in a mesh formed by PVA and glycerin. When phytoncide essence is added more than the capacity of the mesh made by PVA and glycerin, phytoncide essence added is easily volatilized and wasted. Since it is possible to add an excessive amount, waste should be used in an appropriate amount, and it is preferable not to contain more than 50 parts by weight of phytoncide essence depending on the composition amount of the given PVA.

Phytoncide essence, the basic raw material for the production of sustained-release phytoncide, is extracted from conifers such as various trees, cypress, pine, cedar, gypsum, and pine trees containing phytoncide by various methods such as steam distillation, solvent extraction, and supercritical extraction. It is a highly volatile organic phase liquid that can be used as the main component of terpene, α-pinene, DL-camphene, β-pinene, 3-carene, myrcene, D-limonene, β-phellandrene, terpinolene, bornyl acetate, β-caryophyllene, etc. Various ingredients are included. In addition, water-soluble phytoncide is a phytoncide component dissolved in water when extracting a tree containing phytoncide as a solution of water phase, as described above, Verbenone, alpha-Terpinieol, Fenchol, Camphor, Borneol, p,alpha-Dimethylstyrene, Myrtenol, Carveol, Carvone and d-Fenchone are the main ingredients. When extracting phytoncide by steam distillation method or water vapor distillation method, a water-soluble phytoncide solution in which water-soluble phytoncide components are dissolved in an organic phase phytoncide essence and a water phase in a distillate is prepared. In the present invention, an organic phase phytoncide essence and a water phase phytoncide aqueous solution were prepared and used by using a steam distillation method or a steam-water distillation method from a pine tree or pine pine tree. However, pine trees or pine trees are not limited to trees that provide phytoncide by-products, and it is also possible for cypress, cedar, and spheroid trees, and all trees that emit phytoncide can be targeted for sources of phytoncide to be used as a raw material for sustained phytoncide production. have.

In the present invention, the reason why two methods of distillation of phytoncide is extracted from a tree containing phytoncide is either steam distillation or water-water distillation. This is because water distillation may be required.

The physiological activity of phytoncide may differ depending on the components of the organic phytoncide essence obtained depending on the type of tree that provides phytoncide, but the main component is terpene and there is no significant difference in the role of physiological activity, so phytoncide essence is obtained from some trees. Doesn't make a difference.

The sustained release phytoncide can be manufactured in various ways depending on the method of introducing it into a disposable sanitary napkin. That is, the sustained form of phytoncide can be prepared as a liquid solution for coating, and can also be used in a film form and a granular form.

In addition, a special functional sanitary napkin can be proposed by adding a component having the purpose of treating vaginitis to the sustained phytoncide. Vaginitis is a common disease in women, like the common cold. The inside of the vagina maintains a certain acidity by derder line bacillus, thereby making the vagina self-cleaning. However, when the acidity is lowered for some reason, the self-cleaning action of the vagina decreases, so the resistance to invasion of bacteria may decrease. Vaginitis is caused by certain bacteria such as gonorrhea, trichomonas, and candida, and is also caused by E. coli. In addition, even in the case of a systemic disease, white blood cells or various germs may multiply in the vagina. Rarely, inflammation may be caused by an unknown cause. Therefore, prevention of vaginitis is more effective than treatment. As a functional sanitary napkin especially effective for women with severe vaginitis by adding various medicines such as “Trihojun”, “Levorin”, “Nistatin” or Iodine, which are various types of vaginal treatments effective in treating vaginitis to this sustained phytoncide. The effect can be expected. In the present invention, iodine was considered as the most common vaginitis prevention and treatment drug.

When the iodine component, which is a drug for preventing and treating vaginitis, is included, the composition of each component is as follows by weight parts of each component.

Polyvinylalcohol (PVA) 1.5 to 70.0 parts by weight

glycerin 2.0 ~ 50.0 parts by weight

Phytoncide Essence 0.01 ~ 40.0 parts by weight

Phytoncide aqueous solution (or water) 10 to 95 parts by weight

Cellulose 0.1 ~ 20.0 parts by weight

Hardener 0.1 ~ 20.0 parts by weight

Vaginitis treatment (iodine) 0.1 ~ 5.0 parts by weight

If the amount of iodine added to the sustained-release phytoncide is less than 0.1 part by weight, the therapeutic action cannot be secured, and even if it is added more than 5.0 parts by weight, the vaginitis treatment and prevention effect is no longer increased.

The functional smart sanitary napkin carrying the sustained phytoncide presented in the present invention, like a normal disposable sanitary napkin, is a top sheet through which secretions such as menstrual blood pass, an absorbent layer through which secretions are absorbed, and a waterproof bottom sheet are sequentially stacked. It has a composition. The structure in which the top sheet, the absorbent layer, and the lower sheet are stacked is the same as that of a conventional disposable sanitary napkin, and the detailed description of the top sheet, the absorbent layer, and the lower sheet is also made of the same material as that of the conventional sanitary napkin.

Therefore, the present invention is to achieve the object of the present invention, in a disposable sanitary napkin including a top sheet, an absorbent layer, and a waterproof layer, the sustained release phytoncide component is impregnated in the top sheet or absorbent layer, and the sustained release phytoncide It provides a disposable sanitary napkin containing. Therefore, the sustained phytoncide is formed in the form of a film between the topsheet and the absorbent layer of the sanitary napkin, or it is granulated to contain it in the absorbent layer, or instead of the film or particleized, the sustained phytoncide is directly lower side inside the topsheet or It is prepared by coating on the inner surface of a sanitary napkin. Alternatively, the nonwoven fabric coated with phytoncide, which has been sustained to be coated on a separate nonwoven fabric, may be cut in the form of a sanitary napkin and installed between the top sheet and the absorbent layer. Currently, among some disposable sanitary napkin products, a light special fabric is installed between the top sheet and the absorbent layer. The special fabric can be coated with sustained release phytoncide. The special fabric is formed of a cloth having water permeability, such as cotton or non-woven fabric. The layer containing the sustained phytoncide is deposited on the upper surface of the absorbent layer. In this case, since the phytoncide layer sustained by the top sheet is fixed to the absorbent layer, the phytoncide layer sustained by release may be laminated without attaching it to the absorber layer. The present invention having such a configuration prevents the skin from being sensitively acted by the phytoncide of the sustained phytoncide layer, soothes skin irritation due to antibacterial and sedative effects, and removes unpleasant odors peculiar to secretions through deodorization and deodorization. The effect is achieved.

In particular, since the present invention has a structure in which the sustained phytoncide layer is impregnated into the permeable fabric, phytoncide is prolonged longer than conventional sanitary napkins containing phytoncide, and a relatively large amount can be divergently applied, thereby deodorizing more effectively. And deodorizing effect and antibacterial effect.

<Preparation Example>

In order to prepare a sanitary napkin containing sustained-release phytoncide of the present invention, sustained-release phytoncide must be prepared, and for production of sustained-release phytoncide, an oily phytoncide essence and water-soluble phytoncide must first be prepared. To this end, the present invention was intended to extract pine tree phytoncide by steam distillation. The raw materials for phytoncide-containing trees are by-products obtained after pine nuts are obtained from pine nuts. 1 kg of this by-product is charged to a 5 L round flask. A separate steam generator was placed to generate steam while maintaining the distillation temperature at 100±3°C so that it passed directly to the lower end of the by-product sample and distilled for a certain time. In the solution obtained by distillation, the oil phase and the water phase are separated by a difference in specific gravity. The supernatant is the phytoncide essence of the organic phase, and the water phase is a water-soluble phytoncide solution containing a water-soluble phytoncide component. Each of these obtained is separated into a separatory funnel, sealed, refrigerated, and used as a raw material for sustained release phytoncide.

<Preparation Example 2>

In order to prepare a sanitary napkin containing sustained-release phytoncide of the present invention, sustained-release phytoncide must be prepared, and for production of sustained-release phytoncide, an oily phytoncide essence and water-soluble phytoncide must first be prepared. To this end, the present invention was intended to extract and use pine phytoncide by steam-water distillation. The raw materials for phytoncide-containing trees are by-products obtained after pine nuts are obtained from pine nuts. 1 kg of this by-product is charged into a round flask with a capacity of 5 L, and additionally, 2,000 ml of distilled water is added enough to contain pine nuts by-product. And after homogenizing for 1-2 minutes, distillation was performed for a certain time while maintaining the same distillation temperature of 100±3°C as in the steam distillation method. In the solution obtained by distillation, the oil phase and the water phase are separated by a difference in specific gravity. The supernatant is the phytoncide essence of the organic phase, and the water phase is a water-soluble phytoncide solution containing a water-soluble phytoncide component. The amount of phytoncide essence obtained is relatively small compared to the amount obtained by steam distillation. Each of these obtained is separated into a separatory funnel, sealed, refrigerated, and used as a raw material for sustained release phytoncide. As a result of analyzing the phytoncide essence of the organic phase obtained from pine pine by-products by the steam distillation method and the steam-water distillation method of the preparation example, the main components are α-pinene, β-pinene, D-Limonene, β-myrcene, and 3-carene. Was confirmed. In addition, it was confirmed that Verbenone, alpha-Terpinieol, Fenchol, Camphor, Borneol, p,alpha-Dimethylstyrene, Myrtenol, Carveol, Carvone, d-Fenchone, etc. are the main components of the water-soluble phytoncide solution.

<Example Basic Experiment 1>

This is put in a sprayer and sprayed on a nonwoven fabric to dry at room temperature. The dried nonwoven fabric is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin, and is inserted and installed between the top sheet and the absorbent layer to complete the manufacture of the disposable sanitary napkin. Based on this, the antibacterial and long-acting properties of sustained release phytoncide were confirmed.

Additionally, 10 g of cellulose CMC and 5 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. This is put in a wide plate-shaped mold to form a film, or a thin thin plate is made by a doctor blade method, and then dried at room temperature. The dried film is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin, and is inserted and installed between the top sheet and the absorbent layer to complete the manufacture of the disposable sanitary napkin. Based on this, the antibacterial and long-acting properties of sustained release phytoncide were confirmed.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. As a result, sustained-release phytoncide is formed, which is placed in a sprayer and sprayed onto a non-woven fabric to coat the sustained-release phytoncide and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. The dried and non-woven phytoncide is dried and cut to a suitable size so that it can be inserted into a disposable sanitary napkin. After inserting and installing between the top sheet and the absorbent layer, the disposable sanitary napkin is completed. For the background test to test the persistence and antimicrobial performance of sustained-release phytoncide, the test samples prepared in <Example Background Experiment 1> excluding phytoncide essence and phytoncide aqueous solution were compared based on the test samples. When coated with sustained-release phytoncide, it was confirmed that the persistence of phytoncide remained sufficient for 100 days, and the antibacterial performance of the phytoncide was expressed as it is. Table 1 shows the results.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. As a result, a sustained-release phytoncide is formed, and it is poured into a wide plate-like mold to form a film, or a thin sheet is made by a doctor blade method, and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. This film-type sustained-release phytoncide is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin and inserted into the top sheet and the absorbent layer, or cut into a strip-shaped film and inserted into the top sheet and the absorbent layer to disposable. Complete the manufacture of the sanitary napkin. For the background test to test the persistence and antimicrobial performance of sustained-release phytoncide, the test samples prepared in <Example Experiment 2> excluding phytoncide essence and phytoncide aqueous solution were compared based on the test samples. That is, two cases in which a sustained-release phytoncide was prepared in a film form and a background test sample solution were prepared in a film form were compared. Even when the sustained-release phytoncide was prepared in the form of a film, it was confirmed that the persistence of phytoncide remained sufficiently for more than 100 days, and the antibacterial performance of the phytoncide was also expressed as in the case of coating the sustained-release phytoncide. Table 1 shows the results.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. To this, 10 g of cellulose CMC and 5 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. As a result, sustained-release phytoncide is formed, which is placed in a sprayer and sprayed onto a non-woven fabric to coat the sustained-release phytoncide and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. The dried and non-woven phytoncide is dried and cut to a suitable size so that it can be inserted into a disposable sanitary napkin. After inserting and installing between the top sheet and the absorbent layer, the disposable sanitary napkin is completed. For the background test to test the persistence and antimicrobial performance of sustained-release phytoncide, the test samples prepared in <Example Background Experiment 3> excluding phytoncide essence and phytoncide aqueous solution were compared based on the test samples. That is, two cases in which the sustained phytoncide was coated on the nonwoven fabric and the nonwoven fabric coated with the background test sample solution were used were compared. First, it was confirmed that the persistence of phytoncide was much longer than that of <Example 1>, and the persistence of phytoncide was sufficiently maintained for 180 days or more. This is because, compared to <Example 1>, cellulose and a curing agent are additionally added, and the net effect of containing phytoncide is further increased. In addition, not only the essential properties of the phytoncide were expressed as it was, but also the antibacterial properties were higher compared to the case of <Example 1>. This has the added effect of the added antimicrobial properties of cellulose and curing agent itself, the results are shown in Table 1.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. To this, 10 g of cellulose and 5 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. The sustained phytoncide is formed and placed in a wide plate-like mold to form a film, or a thin sheet is made by a doctor blade method, and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. After drying, the sustained phytoncide is made into a film. This film-type sustained-release phytoncide is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin and inserted into the top sheet and the absorbent layer, or cut into a strip-shaped film and inserted into the top sheet and the absorbent layer to disposable. Complete the manufacture of the sanitary napkin. For the background test to test the persistence and antibacterial performance of sustained-release phytoncide, the test samples prepared in <Example Background Experiment 4> excluding phytoncide essence and phytoncide aqueous solution were compared based on the test samples. That is, two cases in which a sustained-release phytoncide was prepared in a film form and a background test sample solution were prepared in a film form were compared. First, it was confirmed that the persistence of phytoncide was much longer than that of the case where the same film was formulated as in <Example 2>, and the persistence of phytoncide was sufficiently maintained for more than 180 days. This is because, compared to <Example 2>, even if cellulose and a curing agent are additionally added, and the sustained-release phytoncide is formulated in a film form, the net effect of containing phytoncide is further increased. In addition, not only the essential properties of phytoncide were expressed as it was, but also the antibacterial properties were higher than in the case of <Example 2>. This tendency is consistent with the case of comparing the antibacterial properties of <Example 1> and <Example 3>, and there is an effect that the added antimicrobial properties of cellulose and the curing agent itself are added, and the results are shown in Table 1. Same as

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. To this, 10 g of cellulose and 10 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. The sustained phytoncide is formed, and is adhered to a wide plate or made into a thin plate by a doctor blade method and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. After drying, the sustained phytoncide is made into a film. The sustained phytoncide in the form of this film is again finely cut into 1 to 2 mm granules. A sustained release phytoncide molded into this granule is dispersedly inserted into the absorbent layer about 10 g to complete the manufacture of a disposable sanitary napkin. In the case of granulated sustained-release phytoncide, the persistence and antibacterial performance of phytoncide were mixed with the absorbent and granulated sustained-release phytoncide, and the moisture of the absorbent was wetted and the performance of the sustained-release phytoncide was investigated. As a result, phytoncide with sustained and antimicrobial properties sustained release showed almost similar results to those produced in film form. Table 1 shows the results.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 40 g of phytoncide essence are added and stirred well. To this, 15 g of cellulose and 10 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. The sustained phytoncide is formed, and is adhered to a wide plate or made into a thin plate by a doctor blade method, and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. After drying, the sustained phytoncide is made into a film. This film-form sustained phytoncide is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin, and is inserted between the top sheet and the absorbent layer, or cut into a strip-shaped film to be inserted and installed between the top sheet and the absorbent layer. In addition, as shown in <Example 5>, the sustained-release phytoncide formed in the form of a film in the form of a 1 to 2 mm granular sustained phytoncide was dispersedly inserted into the absorbent layer to complete the manufacture of a disposable sanitary napkin. In this case, after disposing the prepared disposable sanitary napkin at room temperature for 180 days or more, the sanitary napkin is disassembled, and the sustained persistence and antibacterial performance of phytoncide persistence and antimicrobial performance for each of the sustained-release phytoncide in the form of a film and granular sustained-release phytoncide in the absorbent layer are performed. Examples 4> and <Example 5> were investigated. After 180 days, it was confirmed that each sustained phytoncide film and particulate phase remained phytoncide in a residual state and also exhibited antibacterial properties.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 60 g of glycerin and 30 g of phytoncide essence are added and stirred well. As a result, sustained-release phytoncide is formed, which is placed in a sprayer and sprayed onto a non-woven fabric to coat the sustained-release phytoncide and then dried at room temperature. The dried non-woven phytoncide is dried and cut to a suitable size so that it can be inserted into a disposable sanitary napkin, and is installed between the top sheet and the absorbent layer and between the absorbent layer and the bottom sheet. Phytoncide completes the manufacture of disposable sanitary napkins that can increase persistence. In this case, after the prepared disposable sanitary napkin is left at room temperature for 100 days or more, the sanitary napkin is disassembled and the sustained persistence and antimicrobial performance of phytoncide remained for each nonwoven fabric coated with sustained release phytoncide, as in <Example 1>. Was investigated. After 100 days, it was confirmed that the non-woven fabric coated with sustained release phytoncide remained in a good condition for sustaining the emission of phytoncide and also exhibited antibacterial properties. In addition, it was confirmed that the dissipation state of the phytoncide was increased as a result of making the sustained phytoncide-coated nonwoven fabric sprayed with moisture to wet the moisture. This is because the phytoncide contained in the network structure becomes easy to diverge as the polymer network structure is decomposed by moisture. These results indicate that the phytoncide is well suited to the intention of the present invention, which is designed to volatilize when necessary depending on the mechanism by which the structure of the molecular network is opened by moisture.

Did. It was confirmed that the sustained release of the phytoncide film in the sustained release of the phytoncide film after 100 days was maintained in a good state and also exhibited antibacterial properties. In addition, as a result of spraying moisture on the sustained-release phytoncide film and making it wet, it was confirmed that the shedding state of phytoncide increased. This is because the phytoncide contained in the network structure becomes easy to diverge as the polymer network structure is decomposed by moisture.

It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. The dried non-woven phytoncide is dried and cut to a suitable size so that it can be inserted into a disposable sanitary napkin, and is installed between the top sheet and the absorbent layer and between the absorbent layer and the bottom sheet. The manufacture of disposable sanitary napkins capable of increasing the antibacterial properties and persistence of phytoncide is completed. In this case, after the prepared disposable sanitary napkin is left at room temperature for 180 days or more, the sanitary napkin is disassembled and the sustained persistence and antimicrobial performance of the phytoncide remaining for each nonwoven fabric coated with sustained-release phytoncide is obtained as in the case of <Example 3>. Was investigated. After 180 days, it was confirmed that the sustained release of phytoncide was maintained in a good condition for the non-woven fabric coated with sustained release phytoncide and also exhibited antibacterial properties. In addition, it was confirmed that the dissipation state of the phytoncide was increased as a result of making the sustained phytoncide-coated nonwoven fabric sprayed with moisture to wet the moisture.

The manufacture of disposable sanitary napkins that can increase the persistence of phytoncide properties is completed. In this case, after the prepared disposable sanitary napkin is left at room temperature for 180 days or more, the sanitary napkin is disassembled to investigate the persistence and antibacterial performance of phytoncide persistence and antimicrobial performance for each of the sustained-release phytoncide in the form of a film, as in the case of <Example 4>. Did. It was confirmed that the sustained release of the phytoncide film in the sustained release of the phytoncide film after 180 days remained in good condition and also exhibited antibacterial properties. In addition, as a result of spraying moisture on the sustained-release phytoncide film and making it wet, it was confirmed that the shedding state of phytoncide increased.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 60 g of glycerin and 30 g of phytoncide essence are added and stirred well. Again, add 10 g of iodine, an effective agent for treating vaginitis, and stir well. As a result, a sustained-release phytoncide having an effective function in the treatment of vaginitis is formed, placed in a sprayer, sprayed onto a non-woven fabric, coated with the sustained-release phytoncide, and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. After the dried sustained phytoncide is attached, the dried nonwoven fabric is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin, and is inserted and installed between the top sheet and the absorbent layer to complete the manufacture of a disposable sanitary napkin having effective performance in preventing vaginitis. For the background test to test the persistence of sustained phytoncide, antibacterial performance, and vaginitis prevention effect, comparison was made based on the test samples prepared in <Example Basic Experiment 1>, except for phytoncide essence and phytoncide aqueous solution. When coated with sustained-release phytoncide, it was confirmed that the persistence of phytoncide remained sufficient for 100 days, and the antibacterial performance of the phytoncide was expressed as it is. In addition, it was confirmed that phytoncide sustained over a period of 100 days or more has an effect of preventing vaginitis. Table 1 shows the results.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 60 g of glycerin and 30 g of phytoncide essence are added and stirred well. Again, 15 g of cellulose, 10 g of iodine as an effective agent for treating vaginitis, and 5 g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. As a result, a sustained-release phytoncide having an effective function in the treatment of vaginitis is formed, placed in a sprayer, sprayed onto a non-woven fabric, coated with the sustained-release phytoncide, and then dried at room temperature.

After the dried sustained phytoncide is attached, the dried nonwoven fabric is cut to an appropriate size so that it can be inserted into a disposable sanitary napkin, and is inserted between the top sheet and the absorbent layer to complete the manufacture of a disposable sanitary napkin having effective performance in preventing vaginitis. For the background test to test the persistence and antibacterial performance and vaginitis prevention effect of sustained-release phytoncide, phytoncide essence and phytoncide aqueous solution were compared based on the test samples prepared in <Example Basic Experiment 3>, except for the aqueous solution. When coated with sustained-release phytoncide, it was confirmed that the persistence of phytoncide remained sufficient for 180 days, and the antibacterial performance of the phytoncide was expressed as it is.

Add 150 g of PVA to 850 g of phytoncide aqueous solution and stir to dissolve. If there is no phytoncide aqueous solution, distilled water may be used. To this, 70 g of glycerin and 50 g of phytoncide essence are added and stirred well. In addition, 20 g of cellulose and ₃ g of H ₃ BO ₃ as a curing agent are added and stirred sufficiently. As a result, sustained-release phytoncide is formed, which is placed in a sprayer and sprayed onto a non-woven fabric to coat the sustained-release phytoncide and then dried at room temperature. It can be heated to increase the drying rate, but it is not appropriate under conditions of 60 ^o C or more because phytoncide volatilizes and the content of phytoncide contained decreases. Dried sustained-release phytoncide is attached to the dried non-woven fabric, disposable sanitary pads, diapers for patients or the elderly, pet animal's defecation pads, etc. can be installed on the surface or inside of the appropriate size to cut the sustained phytocide supported Sanitary pads, diapers for patients or the elderly, or toilet pads for pets, etc. are prepared. In this case, the sustained release phytoncide can be cut to a suitable size by cutting the coating nonwoven fabric and installed between the top sheet and the absorbent layer and between the absorbent layer and the bottom sheet. In this case, these sanitary pads prepared, diapers for patients or the elderly, and defecation pads for pets are left at room temperature for more than 180 days, and then the sanitary napkin is disassembled to sustain phytoncide persistence and antimicrobial activity for each nonwoven fabric coated with sustained release phytoncide. The performance was investigated as in the case of <Example 3>. After 180 days, it was confirmed that the sustained release of phytoncide was maintained in a good condition for the non-woven fabric coated with sustained release phytoncide and also exhibited antibacterial properties. In addition, it was confirmed that the dissipation state of the phytoncide was increased as a result of making the sustained phytoncide-coated nonwoven fabric sprayed with moisture to wet the moisture. This is because the phytoncide contained in the network structure becomes easy to diverge as the polymer network structure is decomposed by moisture. These results indicate that the phytoncide is well suited to the intention of the present invention, which is designed to volatilize when necessary depending on the mechanism by which the structure of the molecular network is opened by moisture.

Looking at the results presented in Table 1, cellulose CMC and the curing agent H ₃ BO ₃ were added as a whole, but the antimicrobial properties seemed to be relatively low, but this was the difference between the time when the persistence was measured after applying sustained phytoncide in each example. It is due to. That is, when cellulose and the curing agent were not added, it was because 100 days had elapsed since the sustained phytoncide was applied, and when added, it was measured at the time when 180 days had elapsed. When the cellulose and the curing agent were actually added, it was confirmed that the antibacterial properties were maintained at a much higher level than the cases where no antibacterial properties were added at 100 days.

Even when effective iodine was added to the treatment of vaginitis, its performance was affected with sustained release of phytoncide. 100 days have elapsed after applying the sustained phytoncide of <Example 11> and <Example 12> to which iodine was added, but it can be seen that the antimicrobial properties are relatively high. Of course, the efficacy of vaginitis treatment can also be obtained.
