1 is a flowchart for explaining a method of manufacturing a composite functional sanitary glove having a double sheet film structure according to embodiments of the present invention.

Referring to FIG. 1 , the method for manufacturing a composite functional sanitary glove having a double sheet film structure according to embodiments of the present invention comprises mixing a mixed mineral powder, a transition metal material, a functional extract and a dispersing agent and then stirring to prepare a functional mixed composition. Step (S10), mixing and stirring the functional mixture composition, the first resin composition, and the first functional additive to prepare a first sheet film composition (S20), mixing the second resin composition and the second functional additive and stirring By performing an extrusion molding process using the step (S30) of preparing the second sheet film composition, the first sheet film composition and the second sheet film composition, the first sheet film for the inner skin and the second sheet film for the outer skin are laminated. By performing the glove forming process using the step of manufacturing the sheet film (S40) and the double sheet film, it may include the step (S50) of manufacturing a sanitary glove having a double sheet film structure.

First, the manufacturing method is demonstrated for the 1st sheet film composition which is a sheet film composition for endothelium.

After mixing the mixed mineral powder, the transition metal material, the functional extract and the dispersing agent, a functional mixture composition can be prepared (S10).

The mixed mineral powder is for far-infrared radiation, anion radiation and antibacterial effect, and may include nano-fine particles obtained from mixed calcination and pulverization of quartz, alumina, calcium oxide and zeolite.

Specifically, the mixed calcined pulverized product may be prepared by calcining quartz, alumina, calcium oxide and zeolite at a temperature of 900 to 1100° C. for 30 to 60 minutes, and then pulverizing to have a particle size of 100 to 300 μm. Preferably, the mixed calcined pulverized material may be a mixed calcined pulverized material of quartz, alumina, calcium oxide and zeolite in a weight ratio of 1:1:0.5 to 1:1~2, through which the interaction of the mixed mineral powder As a result, the antibacterial effect of far-infrared radiation and the generation of negative ions can be strengthened. And, to obtain the nanoparticles from the mixed calcination pulverized product, a nanoparticle manufacturing method using a supercritical fluid, for example, a supercritical rapid expansion method (RESS; Rapid Expansion of Supercritical Solutions) may be used. The average particle diameter (ie, particle size) of the nanoparticles may be 0.1 to 0.3㎛.

The transition metal material is intended to increase antibacterial and deodorizing properties by impregnating the porous material of the mixed mineral powder, for example, Cu(II), Fe(II), Ag(II), Ni(II), Pt(II) and Pd ( II) may include at least one material. That is, the mixed mineral powder impregnated with the transition metal material can further improve antibacterial and deodorizing performance due to the high oxidizing power of the transition metal. For effective impregnation of the transition metal, the functional mixture composition may be stirred at a temperature of 60 to 80° C. for 1 hour to 3 hours.

The functional extract is intended to improve antibacterial, sterilization, antioxidant, skin soothing and skin trouble prevention effects, and may include an extract obtained from dried shell powder containing a mineral component and dried plant powder containing a polyphenol component. Hereinafter, a detailed manufacturing method of the functional extract will be described with reference to FIG. 2 .

2 is a flowchart for explaining a method for producing a functional extract according to embodiments of the present invention.

Referring to FIG. 2 , to prepare the functional extract, purified water, dried shell powder, dried plant powder and alcohol are mixed to prepare a first mixture and then a heating process is performed (S11), the first heating process is performed After preparing a second mixture by adding an organic acid or an alkali salt thereof to the mixture, performing an aging process (S12) and separating and extracting an aqueous solution from the second mixture on which the aging process was performed to obtain an extract (S13) may include

In detail, the first mixture may be prepared by mixing purified water, dried shell powder, dried plant powder, and alcohol (S11).

Purified water may be used as a solvent for effectively dissolving or dispersing each component.

Dry shell powder can be used by grinding and mixing one or more types of shells of all types generated from animals that form shells. In general, shells contain calcium carbonate (CaCO3) as the main component and calcium phosphate Ca3(PO4)2] and magnesium carbonate (MgCO3) in small amounts. Calcium phosphate is 1~2%, and it is adhered to the organic matter peculiar to mollusks called conchiolin, and there are pigments or metal compounds here, so it shows the color or pattern peculiar to the shell.

As an example, the dried shell powder may use various shells such as conch, oyster, cockle, abalone, and scallop, and preferably, two or more kinds of pulverized products among shells of conch, oyster, cockle, abalone, and scallop are mixed. can be used In addition, the dried shell powder may be used that is pulverized to have a particle size of 100 to 250 um after calcining the shell from which foreign substances are removed at a high temperature (eg, a temperature of 1000 to 1200 ℃). The particle size of the dried shell powder is to increase the extraction efficiency of the useful components extracted during heating of the first mixture. If the particle size exceeds 250um, the extraction efficiency is lowered, and when the particle size is less than 100um, the grinding process becomes complicated and the process efficiency is reduced. can fall

The dried plant powder is a pulverized product of a dried plant containing an active ingredient (eg, a polyphenol compound) for antibacterial, antiseptic, and antioxidant properties, and may include, for example, a pulverized product of green tea, sancho persimmon, and Japanese cypress.

Green tea (Camellia teaceac) is known to have a function of supplying nutrients of vitamins and minerals, and satisfying preferences such as taste and aroma. The main component of green tea astringent taste is catechin, a polyphenol component, and depending on its derivative, catechin is epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin. It can be classified as epigallocatechin gallate. The content of catechin reaches about 8 to 20% of that of dried green tea, and it is soluble in water and eluted into water when boiled with water. On the other hand, green tea contains various physiologically active substances. In particular, catechins reduce blood LDL cholesterol, thereby inhibiting the formation of blood clots and preventing arteriosclerosis, inhibiting the formation of lipid peroxide and preventing fat oxidation. It has been found that it is also used as a natural antioxidant. In addition, green tea inhibits the growth of cancer, inhibits the growth of cancer along with anti-aging, and has an anti-toxin effect that neutralizes toxins, so it is also known to have an effect of preventing food poisoning.

Zanthoxylum schinifolium (Zanthoxylum schinifolium) has a warm nature, warms the inside, relieves pain by driving away cold air and moisture, and has insecticidal and detoxifying properties. Sancho contains about 7% of essential oil, among them geraniollimonene and cumic alcohol. Recently, it has been reported that the essential oil extracted from the seeds of sancho tree has local anesthetic and analgesic action, and suppresses Escherichia coli, erythrobacteriaceae, cocci, diphtheria, Staphylococcus aureus, and dermatophytes by antibacterial action.

The persimmon tree (Diospyros kaki Thunb) is mainly distributed in the central and southern regions of Korea. In addition to the reproductive Shija, the leaves, Shihwa, and cadavers have been used as folk remedies since ancient times. Among them, persimmon leaves are mainly used as tea, and it is recorded in Donguibogam that it is effective in preventing and treating vascular diseases as well as in purpura (vascular inflammation). Persimmon leaves contain various substances such as vitamin C, amino acids, nucleic acids, phenolic compounds, and free sugar. The flavonoids of persimmon leaves exist in glycoside forms such as astragalin, a glycoside of kaempferol, and myricitrin, isoquercitrin, a glycoside of myricetin, a glycoside of myricetin. Persimmon leaves have a high total phenolic compound content of 0.1 to 5.8% compared to other plants, and have excellent antioxidant and antibacterial properties, and are known to be involved in superoxide dismutase (SOD) activity.

Sophora japonica L. is a broad-leaved tree belonging to the legume family and is widely distributed in Korea, China, and Japan. The bark is gray or dark gray, the inner bark is yellow and has a peculiar smell, and the leaves grow alternately. The flowers of the sycamore tree contain rutin, which is known to be effective in strengthening blood pressure, preventing hypertension, and preventing hyperlipidemia. It is known that the fruit of the sycamore tree is effective in improving liver function by lowering the heat of the liver. In addition, it is known that polyphenols are contained in the fruit of the sycamore tree significantly more than other food types, and are effective in preventing aging through the antioxidant and active oxygen release functions of polyphenols.

The dried plant powder is obtained by using the dried organs (eg, roots, branches, stems, leaves or flowers) of green tea, wild pepper, persimmon tree, and firewood, respectively, and it can be used by mixing the powder pulverized to have a particle size of 0.1 to 1 cm. . If the particle size of the dried plant powder is less than 0.1 cm, the grinding process becomes complicated and the process efficiency is lowered, and if the particle size exceeds 1 cm, the extraction efficiency of useful components such as polyphenol compounds may be reduced.

As an example, the dried plant powder may be prepared by mixing the pulverized products of green tea, wild pepper, persimmon tree, and firewood in a weight ratio of 1:1:0.5~1:0.5~1, through which the powder extracted from the dried plant powder can be used. The synergistic effect and extraction efficiency according to the interaction of the active ingredients can be optimized.

Alcohol is to increase the extraction efficiency of useful components extracted from dried shell powder and dried plant powder, C1 to C4 low-cost alcohol can be used. For example, the alcohol may use ethanol.

According to one embodiment, the first mixture is 15 to 30% by weight of dry shell powder mixed with two or more kinds of pulverized products of conch, oyster, cockle, abalone, and scallop shells, green tea, sancho, persimmon tree, and pulverized product of scallop tree It can be prepared by mixing 10 to 25% by weight of dry plant powder, 10 to 20% by weight of alcohol, and the remainder of purified water mixed in a weight ratio of 1:1:0.5 to 1:0.5 to 1, followed by stirring. If the dry shell powder is less than 15% by weight, the content of the extracted mineral component is low, and if it exceeds 30% by weight, the extraction efficiency may be reduced. When the dry plant powder is less than 10% by weight, the content of the extracted active ingredient is small, and when it exceeds 25% by weight, the extraction efficiency may be reduced. In addition, when the alcohol content is less than 10% by weight, the extraction efficiency is lowered, and when it exceeds 20% by weight, the solubility may be reduced.

The heating process of the first mixture may be performed at a temperature of 80 to 100° C. for 60 to 180 minutes. During heating of the first mixture, a mineral component may be extracted from the dried shell powder, and an active component such as a polyphenol-based compound may be extracted from the dried plant powder. When the heating temperature of the first mixture is less than 80 ℃, the extraction efficiency is lowered, and when it exceeds 100 ℃, deformation of the extracted component may occur. During the heating process of the first mixture, the useful ingredients extracted from the dried shell powder and the dried plant powder may have antibacterial, sterilizing and skin trouble improving effects.

Then, an organic acid or an alkali salt thereof is added to the first mixture subjected to the heating process to prepare a second mixture, and the second mixture may be aged (S12).

The organic acid or its alkali salt can be used as a natural antibacterial material that promotes the secondary extraction of mineral components from the dried shell powder during the aging process and inhibits the growth of bacteria in the second mixture.

The organic acid may be a mixture of two or more selected from acetic acid, citric acid, malic acid, lactic acid, and ascorbic acid. As the alkali salt, an alkali metal salt or an alkaline earth metal salt of the organic acid may be used. For example, the alkali salt may include a sodium salt, a potassium salt, a calcium salt, and the like of the organic acid.

According to an embodiment, the second mixture may be prepared by adding 5 to 10 parts by weight of an organic acid or an alkali salt thereof per 100 parts by weight of the first mixture to which the heating process is performed and stirring. If the organic acid or its alkali salt is less than 5 parts by weight, the extraction efficiency and antibacterial effect of the mineral component is reduced, and when it exceeds 10 parts by weight, solubility may be reduced.

The aging process is for the generation of a synergistic effect according to the sufficient mixing of the useful components in the second mixture and the interaction of each component therethrough, and may be performed at a temperature of 15 to 25° C. for 24 to 36 hours. If the aging proceeds for less than 24 hours, the ingredients in the second mixture may not be sufficiently mixed so that the efficacy of each component may not be properly exhibited, and if it exceeds 36 hours, the aging may already be completed and the efficiency of the operation may be reduced.

Next, by separating and extracting the aqueous solution from the second mixture subjected to the aging process, the functional extract can be obtained (S13).

A variety of known methods may be used to separate and obtain an aqueous solution from the second mixture subjected to the aging process. For example, a functional extract may be obtained by removing the residue from the second mixture through filtration or centrifugation.

The functional extract obtained as described above may contain various useful components for antibacterial, sterilizing, skin soothing and skin trouble improvement effects as well as mineral components and polyphenols.

Referring back to FIG. 1 , as the dispersant, a water-soluble dispersing agent made of a water-soluble polymer may be used. The dispersing agent is purified water, a hydrophilic alcohol solvent, an aldehyde solvent, an ester solvent, and at least one solvent of a ketone solvent, polythiophene polyaniline, polyvinylpyrrolidone, polyvinyl alcohol, polyethylene glycol, polyethylene oxide, poly It may include at least one water-soluble polymer material of etherimide and carboxymethyl cellulose.

According to one embodiment, the functional mixture composition includes nanoparticles obtained from the mixed calcined pulverized product in which the calcined pulverized material of quartz, alumina, calcium oxide and zeolite is mixed in a weight ratio of 1:1:0.5 to 1:1-2 30 to 40 wt% of mixed mineral powder, a transition metal material comprising at least one of Cu(II), Fe(II), Ag(II), Ni(II), Pt(II) and Pd(II) 1 to 3% by weight, 5 to 10% by weight of the functional water extract, and the remainder of the dispersant may be mixed and then stirred. As the mixed mineral powder, transition metal material and functional extract are mixed in a weight ratio in the above-described range, the above-described deodorizing effect can be further strengthened. For example, when each of the mixed mineral powder, the transition metal material, and the functional extract is less than the lower limit, the respective efficacy is not sufficiently exhibited, and when the upper limit is exceeded, the cost may be excessively increased compared to the effect increase.

Then, the first sheet film composition may be prepared by mixing the functional mixture composition prepared as described above, the first resin composition, and the first functional additive and then stirring (S20).

The first resin composition is a film composition for securing the physical properties of the endothelial sheet film, and includes at least one polymer resin of a low-density polyethylene resin (LDPE), a linear low-density polyethylene resin (LLDPE), and a medium-density polyethylene resin (MDPE). may include Preferably, a mixture of two or more of a low-density polyethylene resin, a linear low-density polyethylene resin, and a medium-density polyethylene resin can be used as the first resin composition, thereby increasing the strength of the film and easy stretching to improve productivity there is.

The first functional additive may include a slip agent. The slip agent is an additive for making the film slippery, and it can be applied to the film surface by exuding it to the surface during or immediately after processing. For example, the slip agent may include at least one of Erucamide, Oliamide, and Stearamide. Alternatively, the first functional additive may further include a lubricant and/or an anti-blocking agent in addition to the slip agent.

According to one embodiment, the first sheet film composition is prepared by mixing 5 to 10 parts by weight of the functional mixture composition and 1 to 5 parts by weight of the slip agent per 100 parts by weight of the first resin composition, and for 30 to 60 minutes at a speed of 30-60 rpm. It can be prepared by stirring. If the functional mixture composition and the slip agent are respectively less than the lower limit, the respective efficacy may be insufficient, and if the upper limit is exceeded, the physical properties of the first sheet film composition may be deteriorated.

Next, the manufacturing method of the 2nd sheet film composition which is a sheet film composition for outer coverings is looked at.

The second sheet film composition may be prepared by mixing the second resin composition and the second functional additive and then stirring (S30).

The second resin composition is a film composition for realizing the physical properties of the sheet film for outer skin having higher elongation and tensile strength than the sheet film for endothelium, polyolefin elastomer resin (POE), metallocene linear low-density polyethylene resin (mLLDPE), and low density a mixture of polyethylene resins (LDPE). Preferably, in order to increase the elongation rate and tensile strength of the sheet film for outer skin, the second resin composition contains a polyolefin elastomer resin (POE), a metallocene linear low density polyethylene resin (mLLDPE) and a low density polyethylene resin (LDPE) 2:2: A mixture of 1 weight ratio may be used.

The second functional additive may include a lubricant and an antiblocking agent.

The lubricant is for securing the tension of the sheet film and increasing fluidity during blow molding. For example, a mixture of a C1 to C4 low-cost alcohol and a synthetic surfactant (eg, sodium lauryl sulfate) may be used.

The anti-blocking agent is a material added to improve the opening of the film, and may include stearic acid amide, but the present invention is not limited thereto.

According to an embodiment, the second sheet film composition is a second resin composition in which a polyolefin elastomer resin (POE), a metallocene linear low density polyethylene resin (mLLDPE), and a low density polyethylene resin (LDPE) are mixed in a 2:2:1 weight ratio. After mixing 1 to 3 parts by weight of a lubricant and 1 to 5 parts by weight of an anti-blocking agent in which a C1 to C4 low-cost alcohol and a synthetic surfactant are mixed in a weight ratio of 2:1 per 100 parts by weight, 15 to 30 parts at a speed of 50-70 rpm It can be prepared by stirring for minutes.

Next, by performing an extrusion process using the first sheet film composition and the second sheet film composition prepared as described above, a double sheet film in which the first sheet film for the inner skin and the second sheet film for the outer skin are laminated is prepared can be (S40).

The extrusion process may be performed using a double layer extruder capable of forming a double sheet film. For example, if the first sheet film composition is put into one layer of the double-layer extruder and the second sheet film composition is put into the other layer and then extrusion blown, the two compositions are laminated to form a double sheet film having different inner and outer surfaces. can The temperature of the extrusion molding process may be performed, for example, at a temperature of 120 to 180° C., and a pressing process of pressing the double sheet film at regular intervals in the temperature range after extrusion blowing may be performed.

In the double sheet film prepared in this way, the endothelial sheet film and the outer skin sheet film are not completely heterogeneous materials, but some additives are different in order to improve the functionality required for each, so the laminability of the endothelium and the outer skin is very excellent, and also to the additives. Antibacterial properties, sterilization properties, skin trouble improvement and mechanical properties can be improved.

Then, by performing a glove forming process using a double sheet film, a sanitary glove having a double sheet film structure can be manufactured (S50).

The glove forming process using the double sheet film may include stretching the double sheet film in the long axis direction and performing sealing and cutting processing while the stretched double sheet film is placed in the glove forming apparatus. At this time, the double sheet film may be disposed on the glove forming apparatus so that the portion pressed in step S40 forms the wrist portion of the glove.

In general, when pulling the sanitary glove, the pulling force is mainly concentrated on the wrist. In the present invention, the difference in stretching force between the pressurized part and the unpressurized part is formed in the double sheet film, so that the non-pressurized part is easily It is stretched as it is stretched, but the pressed part can be stretched relatively less. Accordingly, when the wrist part is pulled after wearing the sanitary glove of the present invention, a band may be created while a portion that is less stretched in the form of a pressurized shape, that is, a band is exposed.

In the composite functional sanitary glove of the double sheet film structure prepared as described above, the first sheet film, which is an endothelial sheet film, has a first resin composition for securing film properties, and a transition metal material for far-infrared radiation, anion radiation and antibacterial effect. As it is prepared using the first sheet film composition prepared by mixing and stirring the impregnated mixed mineral powder, and a functional mixture composition containing a functional extract for antibacterial, sterilizing and skin trouble improvement effects, far-infrared radiation and negative ions are generated Through this, antibacterial and sterilizing action can be strengthened, and skin soothing and skin trouble prevention effects can be improved.

In addition, the second sheet film, which is a sheet film for outer skin, is a second resin composition in which polyolefin elastomer resin (POE), metallocene linear low density polyethylene resin (mLLDPE) and low density polyethylene resin (LDPE) are mixed in a 2:2:1 weight ratio. As it is manufactured using a second sheet film composition containing Due to the excellent elasticity of the polyolefin elastomer contained, the effect of a band tightening the wrist region can be obtained. If you hold and pull the sanitary glove after wearing it, the outer skin is stretched and a band is formed on the wrist area and tightened so that it does not come off easily, so the wearability of the wrist can be improved.

As a result, it may be possible to provide a composite functional sanitary glove having a double sheet film structure with improved wrist fit, skin soothing and skin trouble improvement effects along with strengthening of antibacterial and sterilization effects through infrared radiation and generation of negative ions.

Hereinafter, the present invention will be described in detail through examples.
