Description

TECHNICAL FIELD The present invention relates to a method for producing a water-containing tissue paper having antibacterial and antifungal functions, and more specifically, a non-woven fabric used for a water-containing tissue paper (ie, wet tissue), a cotton tissue or a paper tissue base, or an antibacterial material. And tissue paper manufacturing water in which nano-sized particles having antibacterial and anti-fungal functions are mixed with a tissue paper base (particularly non-woven fabric) manufactured by mixing nano-sized metal particles having anti-fungal functions. The present invention relates to a method for producing a water-containing tissue paper having antibacterial and antifungal functions.

In general, disposable water-containing tissue paper containing moisture (ie, wet tissue) is used in commercial offices (for example, restaurants) and public facilities (eg, mass transit means) for the general public. It is mainly used for the purpose of hygienically washing parts of the body when using medical institutions, etc., or for post-treatment of infant excrement.

Since the water-containing tissue for such purpose is mainly washed in a state where it is in direct contact with the skin, the stability to the skin and the ability to remove foreign substances remaining on the skin must be good.

Therefore, when using water-containing tissue paper in general, it is necessary to cut soft paper and fibers (especially non-woven fabric) that does not irritate the skin into a predetermined size, and then make tissue paper production water (preferably Is packed in a state of containing purified water), for example, sealed in a wrapping paper of synthetic resin material.

In general, a non-woven fabric as a typical tissue paper base applied to the production of hydrous tissue paper is manufactured in a felt shape by arranging fibers in parallel or indefinite direction and bonding them. For example, synthetic fibers such as viscose rayon, polyester, and polypropylene, cotton, and natural pulp tend to be used.

The processing methods of the nonwoven fabric are roughly divided into dipping type and dry type, and in the case of dipping type, a synthetic resin adhesive is applied to the fiber, similar to the paper making type for paper production. Then, it is dried and heat-treated. In the case of the dry type, the fiber is made into a thin cotton-like shape, and the synthetic resin is ejected and heated to dry.

In addition, the types of non-woven fabrics include dry-bonded non-woven fabrics including chemically bonded non-woven fabrics, heat-bonded non-woven fabrics, air-laid non-woven fabrics, wet non-woven fabrics, needle punched non-woven fabrics, spanless or spunlace (water flow bonding method) non-woven fabrics, spunbond non-woven fabrics, Includes meltblown nonwovens and stitch bonded nonwovens.

Here, the chemically bonded non-woven fabric is produced through a drying process by infiltrating the adhesive onto the fiber at the time of web bonding, and a deposition adhesion method in which the adhesive is deposited by the adhesive infiltration method, and A spray method in which an adhesive is sprayed to bond is used, and the types of non-woven fabrics by the deposition adhesive method include unidirectional non-woven fabrics, bi-directional non-woven fabrics, and composite tissue non-woven fabrics.

Textiles suitable for the production of the chemical bond include viscose rayon, polyester, and fiber mixed with viscose rayon and polyester, and according to the production method of the chemically bonded nonwoven fabric, when forming a web Although the shape and characteristics of the nonwoven fabric can be changed depending on the type of adhesive used, the adhesive includes a water-insoluble adhesive, a water-soluble adhesive, a soft adhesive, and a hard adhesive.

The chemically bonded non-woven fabric can be produced in various forms according to changes in production form, fiber, adhesive, etc., and has a wide range of uses and various uses. For interior materials of electronic products, filters, adhesive tapes, cable protection, civil engineering, cleaners, etc., general use is for artificial flowers and general wrapping paper, medical contact cloth, cosmetic mask packs and the like.

A heat-bonded nonwoven fabric is manufactured by mixing a fiber raw material such as polypropylene having a low melting point plastic and igniting it with heat or pressure, or by melting and bonding a fiber structure to form a web. Production of low weight nonwoven fabric is facilitated.

Examples of the fiber material used for producing the heat-bonded nonwoven fabric include polypropylene, composite yarn (mixture of polyester and PE, blend of PP and PE, blend of polyester and PP), viscose rayon, and polyester. When viscose rayon is used, the viscose rayon alone cannot form a web by heat, and is produced by mixing polypropylene or composite yarn.

Such a heat-bonded nonwoven fabric has low tensile strength, but has a soft texture and excellent water absorption, but does not use adhesives and does not generate harmful substances in the human body by forming a web with heat. In the case of using a composite yarn, it has an advantage and excellent thermal adhesiveness, thereby being used for baby diapers, sanitary napkins, sanitary masks, wet tissues, and wipers.

In addition, the spunbond nonwoven fabric is produced by directly melting and spraying a fiber-producing chip and then press-bonding to form a web. As a raw material chip used for manufacturing the spunbond nonwoven fabric, Primarily, polyester and polypropylene are used, and in some cases nylon is also used.

The spunbonded nonwoven fabric is a long fiber form that is connected from the production start point to the production completion point without breaking the fiber during the injection process. It has the advantages of high strength, durability and chemical resistance, and is generally used for various industries. For automobile interior materials, filters, cable protection, civil engineering, agriculture, coating, etc. General use includes flower wrapping paper, underlaying paper, wrapping material, bed and furniture, and printed matter.

Airlaid non-woven fabrics are manufactured using compressed air and adhesives, and have no vertical or horizontal tensile difference, and are used as filters, wicks, carbeds, foaming agents, wipers (wives, cloths, towels, etc.), insulating materials, etc. .

In addition, wet nonwoven fabrics are manufactured using the same process as the papermaking process, which is the papermaking process, and the pulp is not used as a raw material, but can be freely changed in physical properties. Used for filter bags, diaper covers, etc.

Needle punched non-woven fabrics are manufactured by physically weaving fibers using special needles, but the thickness of the product can be diversified depending on the number of punches and the density of the needles. Mainly used for blankets, filters, cores, coating foaming agents, etc.

Spunlace nonwoven fabric is manufactured by spraying high-pressure water onto the fiber and bonding the web. As the fiber for producing the spunlace nonwoven fabric, viscose rayon, polyester (polypropylene or the like can be used alone or in combination). It is mainly used for medical wicks, daily necessities, coating foam, roofing materials, wipers, etc. and hygiene products because it is generally flexible and breathable and relatively hygienic.

In particular, spunlace nonwoven fabric has a soft texture and excellent water absorption, has excellent cleaning properties, and forms a web using water, so its manufacturing process is particularly hygienic and is mainly used as a raw material for sanitary products. More often used for wet tissues, wipers, cosmetic mask packs and the like.

Melt blown nonwoven fabric is produced by radiating synthetic polymer, making it into ultrafine fiber with high-pressure hot air and bonding it to a uniform molten fiber web, but it has good flexibility, impermeability and insulation, filter, Mainly used for insulating materials, absorbent sheets, wipers, oil-absorbing sheets, sanitary napkins and the like.

In addition, stitch-bonded nonwoven fabrics are made by quilting fibers with yarn without using an adhesive, but they are thin but have high tensile strength and are mainly used for cores and automobile interior materials.

On the other hand, general water-containing tissue paper (wet tissue) supplies tissue paper production water to a part of the non-woven fabric (for example, heat-bonded non-woven fabric) or cotton or paper to partially wash the body. The tissue paper production water that is manufactured so that it can be applied and applied to the production process of the wet tissue paper (wet tissue) is added with a moisturizing agent useful for the skin, or a disinfectant for sterilization In addition, surfactants for cleaning (removing) foreign substances such as cosmetics are used, and most hydrous tissue paper (wet tissue) is contaminated with non-woven fabric itself and alteration of substances added to the tissue paper production water. In general, chemical preservatives, alcohols, and fragrances for odor mitigation are added to prevent this.

Here, the chemical preservative used in the production of the above water-containing tissue paper is, for example, benzoic acid, sorbic acid, methylparaben, ethylparaben, propylparaben, butylparaben, carbamates (3-iodo-2-propynylbutylcarba Mart), benzimidazoles ((4-thiazolyl) benzimidazole), 2- (4-thiazolyl) -benzimidazole, benzalkonium chloride, polyvinyl butyral, diiodomethyl p-tolylsulfone, 2,4,5,6-tetra Chloroisophthalonitrile, parahydroxybenzoic acids, etc. are used, but this is not only irritating to the skin, but also causes skin rashes, especially in infants with weak immunity, the preservative component may enter the body through the skin. Likely to accumulate, this is atopic skin There is also a possible cause of the disease.

That is, the use of water-containing tissue paper containing such additives, particularly chemical preservatives, may irritate the skin and cause harmful effects on the human body, and may be irritating by the use of disinfectants and alcohol. Odor is also generated and gives discomfort.

In addition, the wet tissue paper (wet tissue) is maintained in a sealed wrapping paper with an appropriate humidity, even when sterilizing disinfectant and alcohol are added. Moisturizers added to hydrous tissue paper (wet tissue), plasticizers and antioxidants added in the production of nonwoven materials (PET, PP, PE, nylon, viscose rayon, pulp, cotton) It is highly probable that molds and bacteria will grow by using adhesives and adhesives as nutrients for microorganisms, and it is especially used in tissue paper for producing hydrous tissue paper (wet tissue) to be used. If a non-woven fabric is contaminated in the process of production or distribution, it will increase the possibility of mold growth as well as the growth of various bacteria. Using the antifungal agent is a chemical preservative for. However, since one kind of a specific preservative cannot exert an effect on all of several kinds of molds, a minimum of 2 to 3 kinds of preservatives are used separately, and the total amount used is usually 3, The reality is that a large amount can only be added to the extent of 000 ppm to 6,000 ppm.

Therefore, recently, when chemical anti-fungal agents are added to tissue paper production water used in the production of hydrous tissue paper (wet tissue), it is highly likely to cause skin irritation. Thus, the use of nanosilver as an antibacterial and antifungal agent is considered.

As an example, Korean Patent Publication No. 10-2006-1758 solves the yellowing phenomenon and the blackening phenomenon caused by light components, which are unique to silver, when silver colloid is produced and used as an antibacterial agent. In addition, a technique for producing an antibacterial and odorless and nontoxic silver solution for the human body and applying it to a hand towel is disclosed.

According to the technique, after quantifying the silver colloid solution (silver solid powder 150 ppm) in the first step, sodium hypochlorite as a catalyst agent is added to the silver colloid solution to about 1 ppm in the second colloid solution. In the third step, in the third step, the calcium carbonate is dissolved so that the silver solution has a pH of 8.5 while stirring and adding calcium carbonate as a catalyst agent to the result obtained in the second step, In the fourth step, sodium acetate is added to the result of the third step and the pH is adjusted by stirring to pH 7.5, and in the fifth step, the silver solution compound of the fourth step is filtered. In the sixth step, a wet colloidal antibacterial agent that is not yellowed is prepared, and in the sixth step, a wet tissue material (eg, non-woven fabric) is dipped in the silver solution so that it does not become yellowish (ie, hydrous tissue paper The manufacture.

That is, in the above-described method, when silver is colloidalized, it solves the problem of discoloration caused by halogen compounds, light components, alkali solutions, and other toxic substances that are inherent to silver, so that white wet tissue, etc. In order to use it as an antibacterial agent, calcium chloride is synthesized and yellowed by adding chlorine, which is a halogen substance, to the silver solution in the first step so that the pH becomes weakly alkaline. ing.

Further, when sodium acetate is added to the above solution to neutralize it, the yellowed silver solution forms a transparent white while showing a transparent white color. It is described that a colloidal solution is obtained.

However, although the above technique does not discuss its feasibility, it focuses only on the production of wet tissue with the emphasis only on the prevention of yellowing of the silver solution, but in fact, to control and eliminate mold. In the process of producing wet tissue with the specific silver solution produced in the first to fifth steps, the technical data for the preferred size of the silver solid powder applied to the The technical content is limited, and there is no specific limitation on whether the silver solution is an ion or a metal, thereby causing problems with its antibacterial and antifungal effects and sustainability. . That is, in the case of ions, unlike metal, it can be easily combined with the other ingredients that can remain in the tissue paper raw water and the tissue paper production water, and expecting more sustainability. Have difficulty.

Therefore, the above-described wet tissue manufacturing method cannot predict the effective period in which the manufactured wet tissue can be distributed and the period in which the manufactured wet tissue can be used after the packaging of the wet tissue product is opened. The technology only considers the point of imparting an antibacterial function to the production water of the wet tissue in order to produce a specific silver solution and simply apply it to the wet tissue.

As another example, Korean Patent Publication No. 10-2006-9585 discloses that wet tissue is wetted with water quality containing nano silver in the wet tissue manufacturing process to prevent bacterial growth. In addition, a method for producing an antibacterial wet tissue is disclosed in which a silver material that is harmless to the human body is transferred by a consumer to effectively remove bacteria. According to the method, paper and textiles are disclosed. The wet tissue formed by mixing and impregnating moisture such as nanosilver treated with water and a surfactant, and chemicals such as fungicides and preservatives is impregnated with water treated with nanosilver having a content of 25 ppm to 150 ppm.

However, in the above-mentioned patented technology, for the antibacterial function, in addition to the water treated with nanosilver, an antifungal agent having antifungal properties must be added and used together. When impregnating paper or textiles with the treated moisture, the nanosilver treated moisture does not provide a specific example for the nanosilver particle size, but only the concentration of the nanosilver is limited. It is only presented. That is, it corresponds to the case where nanosilver is used as an auxiliary agent for the antibacterial function while using an antifungal agent or a preservative.

As is well known, nano-sized silver particles have an increased surface area to exhibit antibacterial, bactericidal and antifungal functions with surface energy, there is no explanation for the size of the particles, but only a specific range of nanosilver particles. The use of the concentration is not only clear in the technical content, but also has a considerable problem in the actual implementation of the technology. In the above wet tissue manufacturing method, wet tissue manufacturing water (that is, tissue paper manufacturing water) is used. ) Only focusing on trying to give only antibacterial functions that are not antifungal.

As another example, Korean Patent Publication No. 10-2006-110952 impregnates silver nanomaterial into spunlace, which is a natural pulp agent, and adds polyglucosamine and ceramic liquid, lotion, aloe, vitamin, etc. By manufacturing wet tissue, it removes heavy metals and waste accumulated in the skin, activates cells to smooth blood circulation, is hygienic, has excellent stability to the skin, and exists in the skin Functional wet tissues having antibacterial and antifungal properties against pathogenic microorganisms have been proposed.

According to the patent publication No. 10-2006-110952, an aqueous solution obtained by mixing 1 to 2% by weight of silver nanopowder with 63 to 69% by weight of purified water, and 30 to 35% by weight of spunlace as a natural pulp agent. The silver nanopowder is immersed in a powder having a concentration of 10 to 100 ppm and a particle size of 1 to 10 nm, or a silver nanocoating powder having a concentration of 10 to 100 ppm and a particle size of 100 to 200 nm. (Capsule), wherein 0.2 to 0.4% by weight of polyglucosamine and 0.6 to 0.8% by weight of a ceramic liquid are mixed in the aqueous solution, and lotion, aloe, Add 1-2% by weight of any one of the vitamins or 1-2% by weight of a mixture of two or more.

However, in the above technique, it is limited to using silver nanopowder or silver nanocoating capsule, and in particular, when silver nano is used alone at a concentration of 10 to 100 ppm, its concentration is required to retain antibacterial properties. In practice, the technology is difficult to implement and apply.

That is, aspergillus is the most serious problem in terms of contamination in the actual wet tissue production process and normal contamination of the nonwoven fabric used in the production of the wet tissue. In order to suppress or remove this, the size is 1 to 10 nm. When silver particles of 100 ppm are used at a concentration of 100 ppm, it has been verified through several experiments that silver alone cannot suppress or remove Aspergillus alone in the environment of a wet tissue packaging bag. In the case where is used alone in tissue paper production water, there has been an experiment that it is only possible to use it at a concentration of about 150 to 200 ppm. Furthermore, even in that case, a yellowing phenomenon appears by reacting with ultraviolet rays, or a precipitate can be formed by reacting with the sulfide component remaining in the nonwoven fabric.

In addition, when nano silver having a size of 10 nm to 100 nm is used, the energy value due to the surface area is reduced, and 200 ppm which is an antifungal holding concentration when the particles having the size of 1 to 10 nm are used. It has been confirmed several times through experiments that mold can be suppressed only by using a concentration of 2 to 4 times the concentration.

In addition, when the silver nanoparticles are coated (encapsulated), the technology is used to coat the surface of the silver nanoparticles, or to encapsulate the silver nanoparticles entirely inside the capsule. There is a high probability of offsetting the surface energy that can react at the surface of the nanoparticle, and the metal nanoparticles required by the present invention, that is, not only silver, but also non-coated nanoparticles such as platinum, gold, copper, zinc, selenium, etc. This technology is fundamentally different from the technology that uses the energy of the particle surface itself due to its antibacterial and antifungal properties.

Moreover, even if it is assumed that all the technical contents of the above-mentioned Patent Publication No. 10-2006-110952 are appropriate, only powder or silver in a capsule form is used alone, and there is a high possibility of color contamination. Thus, the silver is limited to use only in production water for producing wet tissue, and treatment for antibacterial and mildew control on nonwoven fabric and pulp is considered.

In addition, according to Korean Patent No. 10-0693293 proposed by the present inventor, a wet tissue for washing antiseptics having antibacterial and deodorizing functions using metal nanoparticles and the production of the wet tissue In the method, in order to use nanosilver particles having a size of 10 nm or less or to minimize the amount used, nanosilver particles having a size of 1 to 2 nm are used, and the amount used is 10 nm or less. When using particles of a size of 50 to 100 ppm, use a concentration of 50 to 100 ppm, and when using particles of a size of 1 to 2 nm, use the amount at a concentration of 0.4 to 1 ppm. It is characterized by.

In the above-mentioned patent, nanosilver (silver nano) is used only for tissue paper manufacturing water, and as a result of repeated production several times in the actual mass production process, the defect rate (mold occurrence rate) is Results exceeding 1-5% were obtained. That is, 10,000 packs are produced over three times in fiscal 2006, and after each product is produced, if the storage and distribution period elapses from 7 days to a minimum of 30 days, the average minimum of 100 packs to the maximum Aspergillus has been confirmed to occur in about 500 pack products. The cause of Aspergillus is 50% due to the degree of contamination of the nonwoven fabric itself, 30% due to contamination in the production process, and about 20% due to other causes. It was confirmed. This is because the level of sanitary level of product production is severe for each non-woven fabric manufacturing company, and the degree of contamination of the non-woven fabric is different. Due to the characteristics of the process of manufacturing wet tissue (tissue paper) using the non-woven fabric, This suggests that there is a limit to maintaining a hygienic production process.

That is, as in the above-mentioned patented technology, when nano-silver is mixed in tissue paper production water to provide antibacterial and antifungal properties during the production of the above water-containing tissue paper, There is a high possibility that the nonwoven fabric used in the production itself is contaminated during the production or distribution process, contaminated substances are attached during the handling process, or mold spores in the air are attached to the nonwoven fabric. Therefore, it is difficult to produce water-containing wet tissue (tissue paper) having antibacterial and antifungal functions.

In view of such a situation, on the other hand, taking into account that the above-mentioned nonwoven fabric is contaminated, a technology for voluntarily adding antibacterial and deodorizing functions to the nonwoven fabric has been proposed.

For example, in Korean Patent No. 10-64515, the problem of the human body and environment caused by inappropriate use of antibacterial and deodorant compounds is solved, and the economics due to the necessity of a drying process due to moisture absorption and non-uniform dispersion in the polymer occur. The antibacterial and deodorizing effects are improved to improve the working efficiency such as the rise of pressure and the occurrence of yarn breakage, and to have antibacterial and deodorizing effects to prevent the infestation of viruses, bacteria and mold. An excellent polypropylene spunbond nonwoven fabric and a method for producing the same are disclosed.

That is, according to the patent, nano silver and polypropylene in which pure metal silver particles of 1 nm to 3 nm level are bonded to silica particles of 10 nm or less and polypropylene are melted with a kneader, and the silver content is 0.01. Using a master batch chip manufactured to be 10 to 10% by weight, among the polypropylene spunbond nonwoven fabric or the polypropylene spunbond, melt blown, spunbond multilayered nonwoven fabric, nano silver Addition amount is 10 ~ 1000ppm, melt index (MFR) is 20 ~ 80g / 10min polypropylene chip as main raw material, melted, mixed and homogenized by press machine, through radiation detention After melting and radiating, forming a filament through the cooling and stretching process, move continuously Forming a web on a porous conveyor belt, and transported, by thermal bonding calendar it has been presented to confer stability form.

However, according to the technical content of the above-mentioned Patent No. 10-634515, it is described that silica of 10 nm or less and silver of 1 to 3 nm level are combined, but a specific method of the combination is not shown. However, even assuming that this is the usual possible method when using silica as a support, pure metal silver particles do not require that support except in special cases. When pure metal silver particles are deposited inside the supporting silica, the surface area is reduced, which increases the surface area of the nanoparticles, thereby reducing the increased energy. Can bring.

On the other hand, the method of pasting silver and silica without using silica as a carrier requires that a binder be used for the bonding, but if the binder emits fiber, It becomes a decisive cause.

In addition, when the inorganic silica is pulverized by physical methods, the technology known so far is based on the standard of about 50 nm or less because of the manufacturing technology of the pulverizer, processing tolerances and materials. The current technical level is that it cannot be produced.

Therefore, even if the size of silver is 1 to 3 nm, if the size of silica to which silver is bonded is 50 nm, the size of one nanoparticle must be at least 50 nm. Therefore, as shown, the technical explanation is different from that in which silver having a size of 1 to 3 nm is directly used for the nonwoven fabric.

In addition, in the above technique, when silver (silver) is not a metal and silver ions (Ag +) are used, it is a normal method to produce silica or zeolite as a carrier for its stability. This is different from the nanotechnology raw material used in the present invention, and even if metallic silver particles are used, silica is used together for the stability of the silver particles. Therefore, polypropylene, which is the main raw material mixed and radiated with silica, is only a foreign substance, so that the silver particles of pure metal have the size of nanoparticles, and the nano silver particles are thermoplastic. Compared with the case of using it mixed with resin, in its manufacturing process, its workability (increase in internal pressure of cylinder, wear of screw and nozzle) ) And product reliability (tensile strength, shrinkage, such as stain resistance) there is a case in which not enough.

In addition, the above Korean Patent No. 10-634515 discloses only a method for producing a nonwoven fabric by mixing and melting nano silver particles, which is limited to only a raw material of polypropylene, such as viscose rayon yarn or polyester. It is not described for the production of non-woven fabrics as a raw material.

According to the present invention, when the silver nanoparticles applied to the tissue paper production water react with ultraviolet rays, color contamination occurs or is used in the production process of viscose rayon yarn. Since the sulfide partially remaining in the nonwoven fabric to be reacted with the silver can express the aggregation and precipitation phenomenon, the amount used is minimized to 0.00001 to 0.002 wt% (0.1 to 20 ppm) concentration Is preferable.

It becomes possible to use it for the production of non-woven textile fibers.

However, in the case of viscose rayon, considering the possibility that a phenomenon occurs in which some of the metal nanoparticles used react with the sulfide that is the raw material used in the manufacturing process and agglomerate. Among the above metal nanoparticles, platinum, gold and silver particles are not used.

Also, in the case of pulp and cotton, the degree of mixing is not as strong as the bond between the nanoparticles and the polymer polymer, as in the case of polymers, so the nanoparticles deviate from the pulp and cotton material. In consideration of the possibility of being irritated, copper and tungsten particles that can be relatively irritating to the skin are not used, and the amount of silver used is 0.0005 to 0.01 wt% (5% to the weight of the tissue paper stock).

According to the present invention, in the case of [1] viscose rayon, the above-mentioned germanium, selenium, zinc, copper are added to the raw material addition process of the production machine (pressing machine) immediately before producing and radiating the fiber raw material. Or two or more metal nanoparticles are added therein.

That is, viscose is mixed with sodium hydroxide (NaOH) into pulp and subjected to immersion, pressure bonding and pulverization steps to produce alkali cellulose [(C 6 H 9 O 4 -ONa) n]. Carbon disulfide (CS 2 ) is added to produce a cellulose mixture [(C 6 H 9 O 4 —OCS 2 Na) n], and then the resultant is mixed and melted again with sodium hydroxide (NaOH).

Mix and radiate.

In particular, according to the present invention, the use of stabilizers and additives so that carbon disulfide (CS 2 ) is not used or the reaction with sulfur can be minimized in the process of producing the viscose. In the case of using nanoparticles produced in an increased amount, it is possible to mix the nanoparticles in the final rayon fiber [(C 6 H 10 O 5 ) n] in the stage of producing viscose. A method for producing antibacterial and antifungal rayon fibers that can improve the dispersibility of the particles is proposed.

Further, according to the present invention, in the case of [5] cotton, in the process of manufacturing the raw material of cotton with a nonwoven fabric or yarn, the solution containing nanoparticles is impregnated or mixed and radiated together with the nanoparticles. The method is applied.

Further, according to the present invention, in the case of the above [2] polyester, [3] polyethylene, and [4] polypropylene, the resin of each raw material is mixed so that high-concentration metal nanoparticles can be mixed. As proposed by the Korean patent “No. 10-0599532” granted to the applicant, the metal nanoparticles selected from platinum, gold, silver, etc. in a predetermined proportion of heat, which is the raw material of the plastic product It is mixed with a plastic plastic resin and processed into a master patch chip or a composite chip is processed, and then the master patch chip or composite chip processed product is mixed at a predetermined ratio (for example, 3 to 10% in the case of a master patch, composite In the case of 100%), the raw material having antibacterial and antifungal effects is produced by being mixed with the raw material used and radiated.

[1] Viscose rayon, [2] polyester, [3] polyethylene, [4] polypropylene, [5] cotton, [1] viscose rayon having antibacterial and antifungal properties by selectively treating metal nanoparticles through the above process 6] Pulp material is used alone or in combination with a mixture of two or more thereof, for example, a fiber sheet for products requiring antibacterial and antifungal functions, including hydrous tissue paper (especially non-woven fabric) ) Can be preferably applied.

In addition, the assumed nanoparticles of platinum, gold, silver, germanium, selenium, zinc, copper, and tungsten are the above [1] viscose rayon, [2] polyester, [3] polyethylene, [4 ] Polypropylene, [5] Cotton, and [6] Pulp are used alone or in a mixture of two or more, and each fiber material is used alone or in combination of two or more. The total concentration of the metal nanoparticles used in the final base of the water-containing tissue paper produced in this way does not exceed 0.1 wt% (1,000 ppm) relative to the weight of the water-containing tissue paper base And This is because, when two or more of the assumed metal nanoparticles are mixed and used, the maximum total concentration used is 0 compared with the weight of the nonwoven fabric raw material to be finally used regardless of the combination ratio. This is because the antibacterial and antifungal functions can be exhibited within the range of 1 wt% (1,000 ppm).

Therefore, according to the second example of the present invention, the textile raw material for producing a nonwoven fabric as a textile raw material for producing tissue paper includes gold, platinum, silver, germanium, selenium, zinc, copper, By mixing one or two or more metal nanoparticles selected from tungsten so as to be woven with antibacterial and antifungal functions, it is possible to produce general tissue paper production water (for example, purified water). Alternatively, water-containing tissue paper (wet tissue) having antibacterial and antifungal functions can be produced while using distilled water.

Next, a method for producing a hydrous tissue paper having antibacterial and antifungal functions according to the third example of the present invention will be described.

In the first example, assuming that the nonwoven fabric as a fiber base for producing tissue paper has been subjected to antibacterial, sterilization and antifouling treatments relatively well, the nonwoven fabric has antibacterial and antifungal functions. This is a method for producing a water-containing tissue paper (wet tissue) having antibacterial and antifungal functions by impregnating it with tissue paper production water containing metal nanoparticles. When weaving non-woven fabric, anti-bacterial and anti-fungal metal nanoparticles are mixed into the fiber material, and the non-woven fabric is impregnated with general tissue paper production water (eg, distilled water, purified water) In addition, in the third example of the present invention, the fiber sheet (nonwoven fabric) described in the first and second examples is used. Compared to the case where metal nanoparticles for achieving antibacterial and antifungal functions are mixed on only one side of the water for tissue paper production, the antibacterial and antifungal functions that are economical yet more satisfactory are achieved. In order to obtain a composite antibacterial and antifungal function so that a composite antibacterial and antifungal function can be achieved by containing metal nanoparticles for antibacterial and antifungal function on both sides of the fiber raw material and tissue paper manufacturing water Manufacture paper.

That is, according to the third example of the present invention, primary antibacterial and antifungal properties can be obtained by adding antibacterial and antifungal metal nanoparticles to the fiber base applied as a hydrous tissue paper base. The antibacterial and antifungal metal nanoparticles are contained in the tissue paper production water contained in the antibacterial and antifungal non-woven fabric so that it has secondary antibacterial and antifungal properties. Make it moldy.

In particular, in the case of the first and second examples, in order to produce a satisfactory water-containing tissue paper having antibacterial and antifungal functions, the metal mixed in tissue paper production water or tissue paper raw material is used. The concentration of nanoparticles used should be sufficiently assumed. However, in the case of this third example, both the tissue paper base and the tissue paper production water are mixed with metal nanoparticles with antibacterial and antifungal functions. Specifically, it is used at a concentration of 30 to 50% with respect to the concentration of metal nanoparticles used in the tissue paper production water or tissue paper stock of the first and second examples.

That is, according to the third example of the present invention, the metal nanoparticles mixed in the nonwoven fabric as the fiber base and the tissue paper production water are gold, platinum, silver, germanium, selenium, zinc, copper, One selected from tungsten or a mixture of two or more thereof is included.

Here, for the fiber base according to the third example, as described in the second example, the metal nanoparticles of gold, platinum, silver, germanium, selenium, zinc, copper, tungsten are as follows: Viscose rayon, polyester, polyethylene, polypropylene, and cotton are mixed into a raw material fiber, each alone or in a mixture of two or more.

Preferably, according to the third example of the present invention, for the non-woven fabric (textile raw material) for producing the water-containing tissue paper, the used fiber, that is, viscose rayon, polyester, polyethylene, polypropylene. According to the mixing ratio of cotton, the type and ratio of metal nanoparticles are determined, and the mixing ratio of the metal nanoparticles is impregnated in tissue paper manufacturing water having antibacterial and antifungal functions containing the metal nanoparticles. In consideration of the above, it may be assumed to be lower than that in the second example, but Table 3 below is a tissue paper material in tissue paper production water having antibacterial and antifungal functions containing metal nanoparticles. It represents the mixing ratio of the metal nanoparticles mixed with the fiber material, which is a tissue paper material that is assumed in consideration of the point that the nonwoven fabric raw material is impregnated.

That is, in the second example of the present invention, platinum (Pt; see the transmission electron micrograph in FIG. 1) among the metal nanoparticles mixed in the tissue paper manufacturing base to provide antibacterial and antifungal functions. ) Has a particle size of 1 to 50 nm, and its final use concentration is 0.00005 to 0.001 wt% (0.5 to 10 ppm) relative to the weight of the original fiber.

The gold (Au; see transmission electron micrograph in FIG. 2) nanoparticles have a particle size of 1 to 30 nm, and the final use concentration is 0.00005 to 0.000 compared to the weight of the original fiber. 001 wt% (0.5 to 10 ppm).

In addition, silver (Ag; see transmission electron micrograph and distribution diagram in FIG. 3) nanoparticles have a particle size of 1 to 20 nm, and the final use concentration is 0. 0005 to 0.01 wt% (5 to 100 ppm).

The copper (Cu; see the transmission electron micrograph in FIG. 4) nanoparticles have a particle size of 1 to 50 nm, and the concentration in the fiber base is 0.001 to 0.01 wt% (10 to 10%). 100 ppm).

The zinc (Zn; see the transmission electron micrograph in FIG. 5) nanoparticle has a particle size of 1 to 50 nm, and its final use concentration is 0.003 to 0 relative to the weight of the raw material in the fiber base. 0.03 wt% (30 to 300 ppm).

The germanium (especially organic germanium; see the transmission electron micrograph in FIG. 6) nanoparticles have a particle size of 1 to 50 nm, and the final use concentration is 0.0001 as compared to the weight of the raw fiber in the fiber base. -0.005 wt% (1-50 ppm).

The selenium nanoparticles (see the transmission electron micrograph in FIG. 7) have a particle size of 1 to 50 nm, and the final use concentration is 0.0001 to 0.005 wt% relative to the weight of the raw material in the fiber cocoon ( 1 to 50 ppm).

The tungsten nanoparticles (see the transmission electron micrograph in FIG. 8) have a particle size of 1 to 50 nm, and the concentration in the fiber base is 0.001 to 0.01 wt% (compared to the weight of the base). 10 to 100 ppm).

According to the third example, the same or similar to the above second example, the fiber raw materials ([1] viscose rayon, [2] polyester, [3] polyethylene, [4] polypropylene, [5] [Cotton, [6] Pulp) are independently mixed with metal nanoparticles in the proportions shown in Table 3 above, or fibers of each nonwoven fabric containing the metal nanoparticles selectively. It can be used for the production of a nonwoven fiber fabric in the form of a composite yarn in which raw materials are mixed at a predetermined ratio.

In the case of viscose rayon in this third example as well, in consideration of the possibility that a phenomenon of aggregation occurs due to the reaction of sulfide, which is a raw material used in the production process, platinum among the above metal nanoparticles is used. Do not use gold, silver particles.

Also in the case of pulp and cotton, the degree of mixing is similar to that of polymers, and the bonds between the nanoparticles and the polymer macromolecules are not firm, so the nanoparticles deviate from the pulp and cotton material. In view of the potential for the use of copper and tungsten particles, which are relatively skin irritating, silver particles are likely to react with the pulp thickener to cause color contamination Considering this point, considering the combined use of antibacterial tissue paper production water, the amount used is 0.0005 to 0.002 wt% (5 to 20 ppm) relative to the weight of the raw material.

Further, as shown in Table 3 above, in order to mix the metal nanoparticles, the above [1] viscose rayon, [2] polyester, [3] polyethylene, [4] polypropylene, [5] Cotton, [6] Among pulp materials, [2] Polyester, [3] Polyethylene, [4] Polypropylene are the above-mentioned gold, platinum, silver, germanium, selenium, A method is used in which two or more metal nanoparticles are mixed in any one selected from zinc, copper, and tungsten.

That is, as explained in the second example above, in the case of [1] viscose rayon, the raw material addition process of the production machine (pressing machine) immediately before producing and radiating the fiber raw material One or two or more metal nanoparticles selected from germanium, selenium, zinc, and copper are added.

In particular, according to the present invention, stabilizers and additives are used so that carbon disulfide (CS 2 ) is not used in the viscose production process or reaction with sulfur can be minimized. In the case of using nanoparticles produced by increasing the amount used, mixing the nanoparticles at the stage of producing viscose may result in the final rayon fiber [(C 6 H 10 O 5 ) n ] Can improve the dispersibility of nanoparticles and is proposed as a method for producing antibacterial and antifungal rayon fibers.

In addition, according to the third example, even in the case of [5] cotton, in the process of manufacturing the cotton material with a nonwoven fabric or yarn, the solution containing the nanoparticles is impregnated or mixed with the nanoparticles. The method to be applied is applied.

[6] Also in the case of pulp, a method of selectively mixing the metal nanoparticles in the process water used in the process of dispersing the pulp material in the pulp manufacturing process and the pulp to a predetermined thickness and shape A method of mixing the metal nanoparticles into the thickener mixed in the process to be manufactured, or after the pulp is manufactured in the shape of raw paper, the nanoparticles are jetted and the selected metal nanoparticles are A method of allowing mixing is applied.

Also, in the case of [2] polyester, [3] polyethylene, and [4] polypropylene, as proposed by the above-mentioned patent “10-0599532”, a metal selected from platinum, gold, silver, etc. After mixing the nanoparticles with the thermoplastic resin that is the raw material of the plastic product at a predetermined ratio and processing it into a master patch chip or composite chip, the master patch chip processed product is further added to a predetermined ratio (3 to 10%) In order to produce raw yarns with antibacterial and antifungal effects, the mixture is radiated by mixing with the raw materials used or by using 100% of the composite chip.

[1] Viscose rayon, [2] polyester, [3] polyethylene, [4] polypropylene, [5] cotton, [1] viscose rayon having antibacterial and antifungal properties by selectively treating metal nanoparticles through the above process 6] Pulp materials are used singly or in combination, and are preferably applied to the production of textile fibers (especially non-woven fabrics) for products requiring antibacterial and antifungal functions, including, for example, water-containing tissue paper. Can.

In addition, the assumed nanoparticles of platinum, gold, silver, germanium, selenium, zinc, copper, and tungsten, [1] viscose rayon, [2] polyester, [3] polyethylene, [4] Polypropylene, [5] cotton, and [6] pulp fiber materials can be used alone or in admixture of two or more, and each fiber material can be produced separately or in combination of two or more. In the final base of the water-containing tissue paper, the total concentration of the metal nanoparticles used does not exceed 0.03 wt% (300 ppm) relative to the weight of the base. This is because, when two or more of the above-mentioned assumed metal nanoparticles are mixed and used, the total use concentration is compared with the weight of the nonwoven fabric raw material finally used regardless of the combination ratio. In addition to the primary antibacterial and antifungal efficacy within the range of 03 wt% (300 ppm), the antibacterial and antifungal tissue paper production water can exert its secondary effect, This is because the wet wet tissue (tissue paper) can sufficiently exhibit its antibacterial and antifungal functions.

The tissue paper production water according to the third example of the present invention for achieving the antibacterial and antifungal functions mixed with the tissue paper production raw material exemplified in Table 3 above includes platinum, gold, silver, zinc, germanium, Selenium is used alone or in a mixture of two or more selected from the ratios shown in Table 4, and in the case of tissue paper production water according to the third example, antibacterial and antifungal functions are exhibited. In view of the mixed use with 纎 原 緞, a relatively low mixing ratio is assumed as shown in Table 4 below compared to the first example.

That is, according to Table 4, the antibacterial and antifungal tissue tissue preparation examples illustrated in Table 3 above are mixed into the tissue paper manufacturing water in order to have an antibacterial and antifungal function. Among the metal nanoparticles, platinum has a particle size of 1 to 50 nm, and its final use concentration is 0.00001 to 0.0003 wt% (0.1 to 3 ppm) relative to the weight of tissue paper production water. is there.

In addition, the gold nanoparticles mixed in the tissue paper production water have a particle size of 1 to 30 nm, and the final use concentration is 0.00001 to 0.0005 wt% (0.0. 1-5 ppm).

The germanium (particularly organic germanium) nanoparticles mixed in the tissue paper production water have a particle size of 1 to 50 nm, and the final use concentration is 0.0001 to 0.005 wt relative to the weight of the tissue paper production water. % (1-50 ppm).

The selenium nanoparticles mixed in the tissue paper production water have a particle size of 1 to 50 nm, and the final use concentration is 0.0001 to 0.005 wt% (1 to 50 ppm) relative to the weight of the tissue paper production water. ).

In addition, the assumed nanoparticles of platinum, gold, silver, germanium, selenium, and zinc each have the final antibacterial and antifungal function for the wet tissue (tissue paper) of the third example. The total use concentration of the metal nanoparticles used in a mixture of two or more in tissue paper production water that allows some raw silk to be impregnated is the tissue used It shall not exceed 0.005 wt% (50 ppm) relative to the weight of the paper production water. This is because, when two or more of the assumed metal nanoparticles are mixed and used, the total use concentration is 0.005 wt% relative to the weight of the tissue paper production water to be finally used regardless of the combination ratio. In addition to the antibacterial and antifungal effect within the range of (50 ppm), the metal nanoparticles contained in the nonwoven fabric can further exhibit the antibacterial and antifungal effect. This is because the wet wet tissue (tissue paper) can sufficiently exhibit its antibacterial and antifungal functions.

Also, in this third example, platinum, gold, silver, zinc, germanium, selenium, copper, and tungsten nanoparticles that are used by being included in the fiber fabric (nonwoven fabric) and tissue paper production water, respectively, The basic raw materials, additives (reducing agents, stabilizers) that are selected and used for the production of the nanoparticles and their production methods that match the production characteristics of the respective nanoparticles are described in the first and second examples above.
