The moisture absorption rate of the powdery algae material (10P1) is smaller than that of the porous material (10P2), but in terms of moisture content, the powdery algae material (10P1) is selected to be more dominant than the diatomaceous earth powder (10P1). Can be. For example, since the weight of the powdery algae material 10P1 in a completely hydrated state increases by approximately 8 to 10 times compared to the weight of the dry powdery algae material 10P1, this increases the weight of the diatomaceous earth powder 10P1 by 3 times. Considering that it is a factor of 4, it can be seen that the water content of the powdery algae material 10P1 is higher than that of the porous powder 10P2. The reason why the water content of the powdery algae substance 10P1 is high is that it contains a large amount of water-soluble fiber. The water-soluble fiber has fine pores formed therebetween, and the water content can be dramatically increased because volume expansion is possible while maintaining the structure when water is absorbed.

In addition, in the case of a sanitary napkin using a conventional synthetic compound superabsorbent resin (SAP), the superabsorbent resin absorbs menstrual blood and hardens, causing a foreign body sensation, which makes it inconvenient to wear the sanitary napkin. In the case of seaweed, a representative algae, through the action of alginic acid and mannitol, fibers that make up the carbohydrates of seaweed, the absorbed moisture or blood is gelled into a soft sponge-like form and is absorbed by the sanitary pad. There is an advantage that no foreign body sensation occurs when applied to.

The absorbent pad using the powdery algae material (10P1) can reduce the number of sanitary pads used per day, and can be absorbed to the entire surface of the powdery absorbent material even if excessive menstrual blood bleeds temporarily, so that the label layer ( 110), there is no fear of leakage of menstrual blood. In addition, the powdery algae substance (10P1) reduces or eliminates side effects such as skin diseases and swells while containing moisture to prevent excessive drying of the skin upon contact with the skin, and the organic component is a super absorbent polymer, which is a conventional chemical synthetic resin. Unlike, biodegradable while having a positive effect, such as skin protection or menstrual pain relief effect, an eco-friendly absorbent structure can be provided.

As an example of a porous material, diatomaceous earth is a fossilized single-celled plant called diatom, and more than 90% is made of amorphous silica (SiO ₂ ), and is a physicochemically stable inorganic material. In addition, the diatomaceous earth powder 10P1 is a porous material in which numerous small pores PR are formed on the surface, and is light, and has excellent absorption and deodorization capabilities. In addition, when the organic matter in the pores PR of the diatomaceous earth powder 10P1 is removed, the surface area is maximized to further reduce weight, and the absorption capacity and deodorization capacity may be further improved.

The porous material 10P2 may have a menstrual blood absorption rate equal to or higher than that of the super absorbent polymer (SAP) from the experimental results of the present inventors. As a porous material (10P1), diatomaceous earth powder plays a role of rapidly absorbing menstrual blood at the beginning of menstruation based on a high menstrual blood absorption rate. In place of or in conjunction with the diatomaceous earth powder, a porous natural inorganic material such as activated carbon powder or charcoal powder may be used. Both the activated carbon powder and the charcoal are expected to exhibit the same efficacy in terms of absorption and deodorization as diatomaceous earth powder. In addition, silica gel, starch, and bentonite can be used as long as there is no problem of radiation exposure.

According to an embodiment of the present invention, when the porous material 10P2, in particular, the diatomaceous earth powder and the powdery algae material 10P1 are used together, it is primarily absorbed by the porous material 10P1 having a high moisture absorption rate. A two-stage absorption mechanism in which water is absorbed immediately and the rest of the absorbed material is absorbed by the powdery algae material (10P1) having a second high moisture content is possible, so it is as fast as a superabsorbent resin and absorbs high capacity while absorbing at high speed. After the first absorption of the diatomaceous earth powder 10P2, which is not excessively absorbed, it is slowed down by the powdery algae material 10P1, so that a sufficient amount can be stably absorbed secondarily. In addition, as a result of the present inventor's bridging test on 20 adult women, the absorbent structure containing both a powdery algae material and a porous material did not produce a fishy smell peculiar to algae, which is contained together with the powdery algae material. This is because the fishy smell derived from the powdery algae material was adsorbed and removed by the diatomaceous earth powder.

In an embodiment, the selectively added coffee bean powder 10P3 may be provided by finely grinding coffee beans or coffee grounds (waste coffee powder). Coffee beans are generally made by roasting green beans made by peeling and drying the seeds inside the coffee tree. The peeling process of coffee beans is, for example, obtaining coffee beans through dry processing or flush processing, and the dry processing is to remove the pulp by drying the coffee beans, and the flush processing is to remove the coffee beans in water. It is soaked and the pulp is washed off and processed. The coffee beans obtained by peeling can be completed with brownish coffee beans through roasting, which is a process of roasting or roasting. The powder of coffee grounds (or waste coffee powder) can omit the process of pulverizing coffee beans and can obtain the advantage of recycling waste.

The coffee bean powder 10P3 has absorbing and odor-absorbing ability to absorb and remove absorbed substances and odors as much as its own weight through its fine pores. In addition, the coffee bean powder contains a predetermined amount of caffeine, tannin, protein, lipid, and sugar, and the caffeine component may help relieve pain in blood circulation or menstrual pain when absorbed in the body, and the tannin component It can act to clot the blood.

In one embodiment, the coffee bean powder 10P3 may be used by immersing in brine. In this case, the coffee bean powder may be sterilized to improve preservation. In addition, in the case of using coffee grounds as coffee bean powder, it may be more useful to use it after sterilization through saline immersion.

The coffee bean powder 10P3 helps the absorbent material 10P1 or 10P2 to coagulate or gel the absorbed menstrual blood, so that menstrual blood does not easily escape from the absorbent material 10P1 or 10P2 even when there is a pressure such as external pressure. . The absorbent structure to which coffee bean powder (10P3) according to an embodiment of the present invention is added increases the absorption of menstrual blood, has an effect as a deodorant and fragrance, and the absorbed menstrual blood does not easily leak out of the label by external pressure, so that the user can There is an advantage that it can be used more stably.

When algal powder and a porous material are applied as the absorbent material, or additionally, coffee bean powder is further contained, the absorbent materials of each type may have a complementary relationship with each other in terms of absorption rate and moisture content. For example, initially, the absorption of the absorbed material is dominated by a porous material having a high absorption rate, for example, diatomaceous earth powder, and after that, the absorption of the absorbed material is slow by the algal algae material powder having a higher moisture content than the absorption rate. The absorbed material can be absorbed through a step absorption mechanism.

As described above, according to an embodiment of the present invention, algae, a natural absorbent material capable of inducing even absorption and coagulation of absorbed menstrual blood as well as rapid absorption of menstrual blood without using a superabsorbent resin used in the absorbent pad By using a material and/or a porous material, it is possible to not only improve the discomfort felt when using the sanitary pad, but also obtain positive effects that cannot be obtained from the super absorbent polymer such as skin protection, sterilization, pain relief and soothing effects.

During menstruation, women become psychologically sensitive, and as the time elapses when the constitution and the menstrual blood come out of the body, odors from menstrual blood and vaginal secretions are sometimes observed, which is a fundamental factor of discomfort experienced by women who use sanitary pads. In order to solve this problem, in the case of conventional sanitary pads, a scent-causing compound is sometimes added, but this is a factor that generates an unpleasant additional odor along with the odor of menstrual blood, and it is not desirable because some women dislike the scent depending on their taste. . According to an embodiment of the present invention, since the coffee bean powder 10P3 is used as an auxiliary, the absorption rate of menstrual blood is improved and various odor components can be fundamentally removed by adsorption.

The porous material may be combined on the core 211a in the form of fine powder. The algae material may be combined in the form of fine powder on the core 211a, or the extracted fibers or fine fibers may be coated in the form of a film on the core 211a. For example, after dispersing and stirring the core 211a and algae in a solvent such as water, a resultant product coated with the algae material on the core 211a is obtained and dried to provide a composite absorbent material (10CPa). .

Referring to FIG. 4B, a composite absorbent material 10CPb according to another embodiment has a core-shell structure similar to the composite absorbent material 10CPa of FIG. 4A. The core 211b includes an algae material, a porous material, or a mixture thereof as an essential component, and optionally may further include coffee bean powder. In addition, the shell 212b may include at least one selected from the group consisting of natural pulp, natural fibers, and biodegradable resins. The shell 212b may be bonded to each other by bonding or thermocompression bonding on the core 211b, and the present invention is not limited thereto.

4C and 4D, the composite absorbent materials 10CPc and 100CPd according to another embodiment) are similar to the composite absorbent materials 10CPa and 10CPb of FIGS. 4A and 4B, and the cores 211c and 211d and the core ( It has a core-shell structure including shells 212c and 212d surrounding 211c and 211d. The core 211c of FIG. 4C and the shell 212d of FIG. 4D contain algae, a porous material, or a mixture thereof as an essential component, and optionally, may further include coffee bean powder. Further, the shell 212c of FIG. 4C and the core 211d of FIG. 4D may include at least one selected from the group consisting of natural pulp, natural fibers, and biodegradable resins.

Experimental Example 1

In the present invention, a synthetic compound super absorbent polymer (SAP), which is a conventional absorbent material, is not used, but is abundantly present in its natural state, has excellent moisture absorption rate due to high content of water-soluble fiber, and is beneficial for bleeding from skin and menstruation of women. An absorbent pad was prepared by using an absorbent material including seaweed powder, diatomaceous earth powder, and/or coffee bean powder, which is an abundant particulate algal substance. Through the experiment, it was confirmed that the absorbent pad made of natural absorbent material quickly absorbs menstrual blood and is gelled, and at the same time, a small amount of iron or calcium in the blood and a natural coagulation reaction occur, preventing leakage or burying of menstrual blood.

Comparative Example 2: Super absorbent polymer (SAP, LG Chem)

In Table 1, the initial absorption time is the time that moisture is absorbed as soon as moisture comes into contact with the absorbent material, and the final absorption time is the time taken for all the moisture to permeate into the absorbent material. The faster the initial absorption rate of the absorbent material, the shorter the initial absorption time, and the slower the absorption rate of the absorber material increases the final absorption time.

In the initial absorption time, seaweed powder, which is an algae material according to Example 1, exhibited an amount of absorption equivalent to that of pulp or superabsorbent resin. Diatomaceous earth powder, which is a porous material, exhibited the same or greater absorption rate than the superabsorbent polymer of Comparative Example 2. In the final absorption time, the absorbent material of seaweed and diatomaceous earth powder according to Example 2 had the same value of the initial absorption time as compared to the superabsorbent polymer of Comparative Example 2, and the value of the final absorption time was slow and slightly compared to the superabsorbent resin When it is larger, the problem of overabsorption and overabsorption can be solved compared to the superabsorbent polymer.

In addition, it was confirmed that the absorbent materials according to Examples 1 to 3 did not leak blood out of the absorbent material or smear from the surface. In particular, in the absorbent materials of Examples 2 and 3, there was a blood coagulation effect, and there was no problem of leakage or burying out of the absorbent pad.

In addition, in terms of odor, the superabsorbent polymer exhibits a natural compound odor, but seaweed powder also generates a moderate odor, but in Examples 2 and 3 in which diatomaceous earth and/or coffee powder are mixed, diatomaceous earth and Odor can be suppressed by the odor absorbing action of coffee powder.

As described above, according to an embodiment of the present invention, an absorbent pad having a laminated structure of a label layer, an absorbent structure, and a barrier layer may be provided. In the case of a sanitary pad using a conventional synthetic compound superabsorbent resin, the superabsorbent resin absorbs menstrual blood and hardens, causing a foreign body sensation, which makes it inconvenient to wear the sanitary pad, but the sanitary pad of the present invention is made of algae, porous Through the absorption mechanism by substances or mixtures thereof, only menstrual blood is quickly absorbed, and absorption of beneficial ingredients such as moisture that is beneficial to the skin is minimized, and menstrual blood is prevented by the blood coagulation of algae substances or additionally included coffee bean powder. There is also an advantage that it is not inconvenient to wear when using a sanitary pad by stably storing it in the absorbent material in a soft gel form.

7 is a photographic image for comparing blood absorption states of the absorbent pad A according to an embodiment of the present invention and the absorbent pad B using a superabsorbent water according to a comparative example. About 10 mL of blood was used, and the same amount of blood was dropped on each of the two absorption pads (A, B) at the same location, and the results were compared.

Referring to FIG. 7, the absorbent pad (A) according to an embodiment of the present invention uses an absorbent structure manufactured by using both diatomaceous earth powder and algae powder as an absorbent material, whereby blood is uniformly absorbed over the entire surface of the absorbent structure. No blood leakage to the surface of the label was observed, and no blood leakage was observed even when a constant external pressure was applied. In contrast, in the absorption pad (B) according to the comparative example, it was confirmed that blood was intensively absorbed in a local area by the superabsorbent water character, and eventually, blood leaked to the surface of the label layer. Leakage was observed.

8 is for confirming the absorption state of the absorbent pad according to an embodiment of the present invention. The left image is a photograph of measuring the weight of the absorbent pad before absorption with an electronic balance, and the right image is about 70 mL of water absorbed. This is an image of measuring the weight of the absorbent pad with an electronic balance. According to the photograph of FIG. 8, it can be seen that the sanitary pad according to an embodiment of the present invention has excellent absorption power, but it shows about 13 times the absorption power compared to the weight of the absorbent material. In addition, it can be confirmed again that the absorbent pad of the present invention absorbs a large amount of water by the high-capacity slow absorption of algae powder and is uniformly absorbed in the entire area of the absorbent structure.

Referring to Table 2, when an absorbent structure was formed with only a pulp support to form an absorbent pad, the thickness of the absorbent pad was increased because the pulp had to be thickened to obtain sufficient absorbency, and when used, the surface was wet and severe leakage occurred. . In addition, it is confirmed that the diatomaceous earth powder and seaweed extract or algae powder, which are porous natural substances as absorbent materials, have excellent absorption power to the extent that their absorption capacity reaches about 8 times, and when applied together with a pulp support, that is, in Examples 4 and 5, the absorption capacity is significantly increased. .
