Description
TECHNICAL FIELD

This invention relates to a manufacture method of wet-tissue with antimicrobial and anti-fungus function with Non-woven fabrics, Cotton fabrics and other tissue papers or nano particle treated on-woven fabrics which already have antimicrobial and anti-fungus function, more particulary to the technology how to make those materials to have antimicrobial and anti-fungus functions by adding nano particles.

BACKGROUND ART

In general, the disposable wet tissues are used at various commercial and public places such as restaurants, public transportation and hospitals by unspecified persons to clean themselves and take care of excrements of kids.

As they clean up by scrubbing the skin with the wet tissue, it is required to have stability with skin and strong function to remove foreign materials from the skin of users.

Therefore, the wet tissues are being manufactured with paper or fabrics of soft materials such as non-woven fabrics, and it is cut to specific sizes and add distilled water before they are sealed and packed in synthetic resin packing material.

The non-woven fabrics as the major raw materials for wet tissue are manufactures by put the fabrics parallel or unfixed direction and combine to make it felt shape. There are Viscose rayon, Polyester (PE), and Polypropylene (PP) as synthetic fibers, and cotton as well as natural pulp as raw materials for wet tissues.

There are basically two ways to manufacture the non-woven fabrics; they are immersion method and dry method. The immersion method is same as sheet forming method to making paper product that spread synthetic resin binder on the fabrics and drying and heating. The dry method is erupt synthetic resin on the fabrics like a cotton sheet and heat and drying.

There are Non-woven fabrics of Chemical bonding type, Thermal bonding type, dry/ wet type including Air Ray non-woven fabrics, Needle punching type, Melt Blown type and Stitch type depending on manufacturing process.

The chemical Bonding type of Non-woven fabric is being manufactured through drying process by having adhesives penetrate into fabrics while web bonding.

And there are two ways to manufacture non-woven fabrics depending on how to make the adhesives penetrate into fabrics: one is sediment adhesion method which is to penetrate by dipping, and the other one is Spray method which is to spray the adhesives on to fabrics. The non-woven fabrics using sediment adhesion method are OB type, CB type and MB type.

The proper fibers to do Chemical bonding are Viscose Rayon, Polyester and blended fibers of Viscose Rayon and polyester. According to the manufacturing method of chemical bonding, the shapes and features of the non-woven fabrics can be differ per the adhesives used for web formulation. The adhesives include soluble types and non-soluble, soft types and hard types.

Non-woven fabrics with the chemical Bonding method can be manufactured in many different ways per its production process, fabrics and adhesives, and it has variety and wide applications such as for automobile, Electronics, internal use for Electronics products, Filters, Adhesive tapes, Civil engineering and cleaner as industrial application and artificial flowers, general pacing materials, medical adhesive tape and cosmetics mask pack as general applications.

Non-woven fabrics of the thermal bonding method is being manufactured by mixing raw materials of Polypropylene(P.P.) which is flammable at low temperature, and melt it by heat or pressure and combine fibrous tissue and form the Web. This method is being used to produce lower weight non-woven fabrics.

There are Polypropylene (PP), Blended Yarn (Polyester+PE, PP+PE, Polyester+PP), Viscose Rayon and Polyester as fabric raw materials for Thermal Boding type of Non-woven Fabrics. As the Viscose Rayon itself is impossible to form the Web, Mix with Polypropylene or Blended fibers.

Such Thermal Bonding type Non-woven fabrics are lower in tensile strength but has soft touch-feeling, superior absorptiveness, adhesive is not required, form the Web by heat which does not generate harmful materials. When the blended fiber is used, it has superior adhesive property by heat, and therefore, it is being widely used for baby diapers, sanitary diapers, sanitary masks, Wet tissues and Wipers.

Span bond type non-woven fabric is being manufactured by for the Web with pressure after melting and spraying the fabric chips. Mainly Polyester and Polypropylene are being used as material chips and sometimes Nylon is also used.

Span bond has the advantage of tensile strength is higher and superior in durability and chemical resistance while it has lower tensile strength because it is filament that does not stop from the starting point to the end in production without cut. It is being used for industrial applications such as interior material for automobiles, Filter, Cable protector, Civil Engineering, Agricultural and Coating, and packing material for flowers, basic wall papers, packing materials, Beds and furniture and printing materials as general industrial applications.

As Air-ray type of Non-woven fabric is being manufactured with Compressed air and adhesives, there is no difference in tensile strength of parallel and horizontal direction.

It is being used as Filter, wick, carpet, forming agent, Wipers (rug, dishcloth, towel) and insulation materials.

Wet Non-woven fabrics use the same manufacturing process as paper manufacturing which is sheet forming method. The difference is that it does not use pulps as materials but uses other fabrics which allow free control of its specification, and being used for Wipers, Towel, Filter bag and cover of Diapers.

Needle-punching type non-woven fabrics are manufactured with special needles to form the web which enables to vary its thickness of the products with number of punching and density of needles. It is applied to Carpet, Blanket, Filter, wick coating agent.

Span-ray non-woven fabrics are manufactured by spraying high pressure water to the fabrics to form the web. Viscose Rayon, Polyester, Polypropylene as itself or blended are used as raw materials. As the products is good in flexibility, breath-ability and hygienic, it is used for Medical wick, household items, Coating agent, roofing materials, wiper and sanitary products.

Specially, as the Span-ray non-woven fabrics have soft-touch feeling, superior absorptiveness of water, superior cleaning function and form web with water, its manufacturing process is hygienic, and therefore it is used mainly for sanitary products such as Wet Tissue, Wiper and cosmetic mask pack.

Melt blown type non-woven fabrics are manufactured by weaving blended high molecule to get ultra thin yarn with high compressed heat and form the web. With its superiority of flexibility, permeability and insulation, it is used for Filter, Insulation materials, Wipers, Oil absorbing sheet and sanitary napkins.

And as the Starch bond type non-woven fabrics do not use adhesives but quilting method, it is thin but high tensile strength and it is used mainly for wick and interior materials for automobile.

The other hands, the general wet tissues are manufactured to clean the body partially by adding specially prepared water to cottons or pulps or some of above-mentioned non-woven fabrics (i.e. thermal bonding type non-woven fabrics and etc.).

Moisturizer and surfactant are generally added to specially prepared water for wet tissue to produce wet tissues. And those wet tissues use chemical preservatives, alcohol and perfumeries to protect contamination of the wet tissues, possible changes of the characters of the materials added and to lessen the bad smells.

The chemical preservatives are Benzoic acid, Sorbic acid, Methylparaben, Ethylparaben, Propylparaben, Butylparaben, 3-iodo-2-propynyl butyl carbonate, 4-thiazolyl-benzimidazole, 2-(4-thiazolyl)-benzimidazole, benzalkonium chloride, polyvinyl Butyral, deiodinemethyl, p-tolyulfanilamide, 2.4.5.6-tetrachliro-iso-butyno-nitryl, p-hydroxybenzoate.

All of those materials are skin irritator and may generate skin problems, and it has high possibility to be accumulated to the body of kids who are weak in resistance and it can be the reason for atopic skin problems.

Again, those types of additives which are chemical preservatives contained in wet tissue can generate irritation to the skin or harmful to human body.

Further, antimicrobial materials and alcohol generate bad smell that gives bad feeling.

Even though the antimicrobial materials and alcohol are added to wet tissues, there is still high possibility for the bacteria and fungus to be increased in the closed containers because the moisturizer, plasticizer, antioxidant, adhesive agents which are the additive materials for non-woven fabrics (PET, PP, PE, Nylon, Viscose rayon, Pulp, Cotton) become nutritive elements to microorganism in the container where the proper temperature is maintained and Ultraviolet rays is blocked.

Further, there is high possibility for the bacteria to be increased and fungus is generated during the manufacturing and distribution process if the non-woven fabrics as raw material for wet tissues are contaminated, and therefore, the chemical preservatives are used. However, as a specific chemical preservatives is not able to cover all different bacteria, it is fact that at least 2-3 different kind of chemical preservatives of large quantity need to be used, total 3,000-6,000 ppm in general.

Accordingly, considering that the chemical preservatives has strong possibility to raise skin problem if it is added to the specially prepared water for wet tissue to kill fungus, using nano silver as a replacement to chemical preservatives to kill fungus are being seriously considered.

For an example, Korean Laid-Open Patent No. 10-2006-1758 shows that Silver colloid as antimicrobial material solved color change problem to yellowish and black and it has antimicrobial effect. It also described on the technology to apply it for Wet Tissues with Silver Colloid of smell-less and harmless to human body.

According to the technology of the above-mentioned Korean Laid-Open Patent No. 10-2006-1758, after forming 100 ppm of nano silver Colloid in the first process, mix about 1 ppm of sodium hypochlorite into this colloid as catalyst in the second process, 150 ppm of nano silver colloid in the first process, mix calcium carbonate as catalyst into the out-put of the second process to get silver colloid of pH8.5 by melting the calcium carbonate in the third process, mix sodium acetate into the out-put of the third process to control to get pH7.5 in the fourth process, produce antimicrobial silver colloid of unchangeable color by filtering silver compound and then, produce wet tissue of unchangeable color to yellow by dip the wet tissue materials into the silver colloid in the last process.

The above-mentioned process shows that it solved the problems of color changes caused by halogen compound and mineral ingredients or lye and other toxic materials to use it as antimicrobial materials to white wet tissues. In the first process, put chlorine (halogen material) into silver colloid and have it react, and compounding calcium carbonate to yellowish color to make the pH weak alkali.

Further, it describes that transparent silver colloid can be made through filtering the floating particles of transparent white color which are formed by neutralization with nitric acid soda.

However, regardless of its reality, it concentrates on protecting against color changes to yellowish to produce wet tissue. It does not contain enough technical information on the optimistic size of solid silver to control and get rid of fungus.

The technical explanation to produce wet tissue with specific silver colloid produced through the 1st -5th process is rather limited, and there is n definition if such silver colloid is ion or metal which gives us doubts antimicrobial efficacy, effects against fungus and its durability. If that is ion, it can be easily combined to other materials which may be remained in the raw fabric and treated water of wet tissue, and it is hard to expect its durability.

The above-mentioned manufacturing method of wet tissue is the technology which make difficult to estimate the durability after open the pack and overall validity of the products but simply considers how to provide antimicrobial function to treated water for wet tissues.

As an another example, Korean Laid-Open Patent No. 10-2006-95685 provides the method of protecting the propagation of microbes by wetting the wet-tissues into nano silver contained water in the manufacturing process of wet tissue and the method how to eliminate the microbes effectively by transferring the harmless nano silver materials to the hands of customers.

According to the method, it is required to mix nano silver treated water of 25-150 ppm to wet-tissue which is formed with compound of nano silver treated water, surfactants, anti-fungus materials and preservatives to papers and fabrics.

However, the above-mentioned Korean Laid-Open Patent No. 10-2006-95685 describes that anti-fungus materials need to be added besides nano silver treated water used for antimicrobial function. But it has no definition on the size of nano silver particles of the nano silver treated water used but only concentration level only. This can be the case only when the nano silver is added as supplements for antimicrobial function while anti-fungus materials and preservatives are also used.

As notices, the nano-sized silver particles shows its antimicrobial and anti-fungus functions by energy of the surfaces with increased surface area, the technology is rather unclear and has practical problem to apply with only limited concentration level unless it explains clearly about the particle sizes. It emphasizes only on adding antimicrobial function instead of anti-fungus function limited to manufacturing water in the wet tissue manufacturing process.

As an another example, Korean Laid-Open Patent No. 10-2006-110952 suggests functional wet tissue that eliminates accumulated heavy metals from the skin, activate cells and have the functions of smoothing blood circulation, hygienic, superior safety to the skin and antimicrobial and antifungal functions against microbes stays on the skin by adding polyglucosamine, ceramic liquid, lotion, aloe and vitamin to nano silver material treated Span lace which is natural pulp.

According to the above-mentioned Korean Laid-Open Patent No. 10-2006-110952, it is to mix 30-35 weight(wt) % of Span lace, nature pulp material to mixed water of 63-69 wt % with nano silver powder of 1-2 wt %. This nano silver power must be either 10-100 ppm in concentration with 1-10nm in size or nano silver coating powder (capsule type) of 10-100 ppm in concentration with 100-200 nm in size. And mix 0.2-0.4 wt % of polyglucosamine and 0.6-0.8 wt % of liquid ceramic into above liquid and add 1-2 wt % of at least two kinds of mixture of lotion, aloe and vitamin or one of them.

However, the technology is limited to apply nano silver powder or nano silver coated capsule and it has some difficulties to execute and apply it to keep anti-fungus function with 1-100 ppm concentration of nano silver itself alone a the concentration level is not sufficient.

In fact, the most serious problem of contamination during the manufacturing process and usual contamination of the fabrics for wet tissue is Aspergillus Niger. It has been already proved through a few experiments that it is not possible to protect or eliminate the Aspergillus Niger by silver alone under the circumstances in the wet tissue pack with nano particle of 1-10 nm with 100 ppm concentration.

An early experiment has been carried out and proved that 150-200 ppm concentration is required to use nano silver alone for tissue manufacturing water.

Further, it still has possibility to have color change into yellow by reacting with UV or form precipitates by reacting with remaining sulfides in the fabrics.

And, it has been confirmed a few times through experiments that 2-4 times of concentration level of 200 ppm are required to keep anti-fungus function as the energy value is decreased per surface size with nano silver of 10-100 nm size.

As the technology to use it after coating the nano silver particles to the surface of the particles or put the particles into the capsule, it has high possibility to offset its surface energy which reacts on the surface of nano silver particles.

This is the basic difference technology in antimicrobial and anti-fungus efficiency from the technology which utilizes the technology of surface energy itself of uncoated nano particles of metals of not only silver but also platinum, gold, copper, zinc and selenium.

And, even though we assume that all the contents of technology in the above-mentioned Korean Laid-Open Patent No. 10-2006-110952 are proper, it uses powder or capsule type of silver only, it has high possibility of color changes and color contamination. It is limited to only to use for manufacturing water for wet tissues, not considering antimicrobial and anti-fungus treatment to non-woven fabrics and pulps.

According to Korean Patent No.10-0693293 suggested by the inventor, it is featured to use below 10 nm particle size to produce preservatives-free cleaning wet tissue which has antimicrobial and deodorizer functions using nano particles of metals or to use 1-2 nm nano silver particles to minimize the quantity to be used. The quantity to use is 50-100 ppm concentration when the particle size of below 10 nm is used, and 0.4-1 ppm concentration is used with 1-2 nm particle size.

In the above-mentioned patent, Nano silver is used for manufacturing water of tissues only. However, the reject rate (fungus incidence) came to 1-5% in practical repeated mass production.

10,000 packs each were produced 3 times in year of 2006, the Aspergillus Niger were found and confirmed from average min. 100 packs to max 500 packs out of each lot in 7-30 days during storage and distribution period. It is confirmed that the Aspergillus Niger were grown 50% by contamination of non-woven fabrics, 30% by contaminated manufacturing process, and 20% by other factors.

This indicates that there are different levels of sanitary environmental conditions contamination levels between the manufacturers and there are limitations to maintain sanitary manufacturing process which is required to manufacture wet tissues with non-woven fabrics.

It is difficult to produce good antimicrobial and antifungal wet Tissue with the above-mentioned patente technology by mixing nano silver into tissue manufacturing water to provide antimicrobial and anti-fungus functions to the wet issue because the non-woven fabrics itself as raw materials can be contaminated during its manufacturing, distribution and handling process or possibility of spores in the air stick to the non-woven fabrics which can be the factor for bacteria or fungus to increase.

Considering this contamination problem of non-woven fabrics, the technology to provide antimicrobial and deodorizer functions to the non-woven fabric itself has been suggested.

As examples, Korean patent No. 10-643515 introduces polypropylene span-bond type non-woven fabrics and its manufacturing technology which solves the problems of human beings and environment caused by using improper antimicrobial and deodorizer chemicals, increases economical efficiency for the necessity of drying process against moisture absorption and work efficiency against increased pressure raised by uneven dispersion in the polymer and problems of cut-thread and provide antimicrobial and deodorizer functions not to allow the virus, bacteria and fungus to inhabit.

According to the Patent, it is produced with pure metallic nano silver particles of 1-3 nm level combined with silica particles of below 1 nm and polypropylene and the added quantity of nano silver is to be 10-1,000 ppm of total polypropylene resin of Polypropylene span bond non-woven fabric, Melt blown span bond multilayer non-woven fabric, using the prefabricated master batch chip contains 0.01˜10 wt % of nano silver and the added quantity of nano silver is to be 10-1,000 ppm of total polypropylene resin of polypropylene span bond non-woven fabric or polypropylene span bond, Melt blown span bond, multilayer non-woven fabric, polypropylene chip have 20˜80 g/10 min Melt Flow Rate(MFR) as a main raw material through the melt, mix, homogenize on the extruder, melt spinning through the spinneret, formed filament after cooling, drawing, formed web on the porous conveyer belt, move to the calendar for heating bond process and then they have stability of formation.

According to the above-mentioned Patent No. 10-643515, silica of below 10 nm is combined to silver of 1-3 nm level; however, there is no description on the detail method of it. Though we assume this is the case silica is used as inclusion body as usual, the silica particles do not require the inclusion body except a special case. The abovementioned technology may reach the result of decreasing the increased energy with increased surface of nano particles because the surface area is decreased if silver particles of the pure metal are contained in the inside of silica, inclusion body.

The way to combine silver and silica without using silica as inclusion body becomes the decisive factor of cut in spinning process regardless of it is used as binder to be coupled.

And, crushing the inorganic silica with physical method, it can be just 10 nm level under the current technology level due to the manufacturing technology of related crusher, tolerance in process and related materials.

Accordingly, the technical explanation is different from the one that uses silver of 1-3 nm to non-woven fabrics directly as described because it must be considered that the nano particle size exceeds 50 nm if the size of combined silica with silver is 50 nm even though the silver size is 1-3 nm.

And, if the patent describes that they use silver Ion instead of silver metal, it is common to use silica or zeolite as inclusion body for the stability, which is different from the nano technological materials and the silica must be foreign materials to polypropylene as it is used together with silica for stability even though it uses silver metal. Accordingly, if we compare it to the case of mixing nano silver particles into thermostatic plastic resin, the productivity (increase of pressure in the cylinder, wear out of screws and nozzles) and reliability (tensile strength, shrinking rate, stain ability and etc.) may not be enough.

And, the above-mentioned Korean patent No. 10-643515 describes the manufacturing method of non-woven fabrics with nano silver particles by mixing to polypropylene materials only.

It does not describe on the manufacturing method of non-woven fabrics that use Viscose Rayon and polyester or others as raw materials for the fabrics.

DISCLOSURE Technical Problem

This invention has been made considering the past technology and its first objective is to provide a manufacture method of antimicrobial and anti-fungus wet tissues by mixing non-woven fabrics of less contamination level or cotton fabrics or papers into antimicrobial water which contain nano particles of either one of platinum, gold, silver, germanium, selenium and zinc or more than 2 of selected metals.

The third objective of this invention is to provide a manufacture method of antimicrobial and anti-fungus wet tissue by mixing nano particles of one or one metals of gold, platinum, silver, germanium, selenium, zinc, copper and tungsten into fabric materials such as viscose rayon, polyester, polyethylene, polypropylene, cotton and pulp to have those fabrics itself antimicrobial and anti-fungus function, and mix this treated fabrics into antimicrobial and anti-fungus water prepared by mixing one or one metal particles of gold, platinum, silver, germanium, selenium and zinc so that both of fabrics and water have antimicrobial and anti-fungus functions.

Technical Solution

According to this invention, to achieve above objectives, the 1st objective provides the manufacture method of antimicrobial and anti-fungus wet tissue with selected non-woven fabrics of blended one or one materials of viscose rayon, polyester, polyethylene, and polypropylene or cotton or pulp by mixing into antimicrobial water which contains nano metal particles of one or more than one of platinum, gold, silver, germanium, selenium and zinc.

According to the second objective of this invention, the manufacture method of antimicrobial and anti-fungus wet tissue comprises a step of forming the antimicrobial and anti-fungus fabrics by mixing one or more that one metal nano particles of platinum, gold, silver, germanium, selenium, zinc, copper and tungsten into blended fabrics of one or more than one out of viscose rayon, polyester, polyethylene, polypropylene, cotton and pulp, and a step of fabricating antimicrobial and anti-fungus tissue by dipping the antimicrobial and anti-fungus fabrics into distilled water or purified water.

According to the third objective of this Patent, it provides the manufacturing method of antimicrobial and anti-fungus wet tissue with selected antimicrobial and anti-fungus fabrics which is formed with one or more than one nano metal particles out of gold, platinum, germanium, selenium, zinc, copper and tungsten and antimicrobial water which contains one of more than one of metal particles out of gold, platinum, germanium, selenium, zinc, copper and tungsten.

According to this patent, in the above-mentioned viscose rayon manufacturing process as fabric materials, one or more than one nano metal particles out of germanium, selenium, zinc, copper and tungsten are added before spinning of rayon yarn, and process with master batch chips or compounding chips produced by mixing one or more than one nano metal particles out of above mentioned gold, platinum, silver, germanium, selenium, zinc, copper and tungsten with thermostatic plastic resin into above mentioned polyester, polyethylene and polypropylene.

And then, spin the master batch chip treated materials after mixing 3-10% ratio into its raw materials or spin 100% of treated compounding chips.

Above cotton is dipped into above mentioned nano metal contained liquid or mixed spin with the nano metal particles.

And the nano metal particles is mixed into water for dispersion process of pulp materials, or mix above nano metal particles into adhesive agent which is used in the process of pulp to have certain thickness and form, or it is mixed with the method of spraying above nano metal particles after the pulp is formed as fabrics.

Advantageous Effects

As described in above, According to the manufacturing method of antimicrobial and anti-fungus tissue based on this invention, the first example can provide enough antimicrobial and anti-fungus efficiency without color changes for long time as it is manufactured hygienically with antimicrobial and anti-fungus water and one or more than one of nano metal particles of gold, platinum, silver, germanium, selenium and zinc into non-woven fabrics or cotton fabrics or pulp which are relatively less contaminated.

In case of the second example, as there are still possibility for the non-woven fabrics to be contaminated and infected during the manufacturing process, transportation and warehousing, and the non-woven fabrics can be the place where the organic materials contained in the wet tissue can be the feeds to bacteria and fungus to live, the increase of bacteria and fungus from wet tissues can be inhibited for long period by dipping antimicrobial and anti-fungus non-woven fabrics into distilled water or purified water after providing antimicrobial and anti-fungus function to raw fabrics of textile materials by mixing one or more than one of nano metal particles out of gold, platinum, silver, germanium, selenium and zinc.

And according to the third example, as the antimicrobial and anti-fungus function is achieved by dipping antimicrobial and anti-fungus textile fabrics of viscose rayon, polyester, polyethylene, polypropylene and cotton which was mixed and formed the web with one or more than one of nano metal particles out of gold, platinum, silver, germanium, selenium, zinc, copper and tungsten into antimicrobial and anti-fungus water which one or more than one of nano metal particles out of gold, platinum, silver, germanium, selenium and zinc, the propagation of microbes which cause the contamination are inhibited from the manufacturing process of non-woven fabrics as textile fabrics, and it is also possible to inhibit the increase of bacteria and fungus even though there are organic materials from the materials contained in wet tissues.

Therefore, it is possible to manufacture multi-function wet tissue that both of customers and manufacturers want regardless of additive raw materials as it protects even the functional additives of skin-beauty and moisturizer functions from being the feeds to bacteria and fungus.

As the antimicrobial and anti-fungus function is added to both of raw fabrics and manufacturing water for tissue in the third example, it is possible to manufacture cheaper but high stability wet tissues by reducing 30-50% in concentration level of nano metal particles comparing to apply it to one of method of either raw fabrics or manufacturing water for tissue even though individual concentration level is different.

Accordingly, this invention considers contamination level of the fabrics (non-woven fabric), hygienic level of its manufacturing process and the contents of the organic additives which are being used to manufacture wet tissues. It is possible to use nano metal particles to either non-woven fabrics or manufacturing water for wet tissue to manufacture wet tissues under this invention. Or, it is possible to use the nano metal particles to each of these one materials (fabrics and water) separately.

And it is possible to control different mixing ratio and quantity of nano metal particles for wet tissue per its fabric materials and water for tissue as shown in the above-mentioned examples 1,2 and 3.

As the wet tissues manufactured with this invention does not use chemical preservatives which can give irritation to skin, it can provide of less irritation to skin of human-being as well as it minimizes the skin irritation and provides safety wet tissues as the chemical preservatives are not used even when many other additives of moisturizer and natural organic materials are added to manufacture multi function wet tissues.

Now, preferred embodiments of this invention will be described in detail with reference to the accompanying drawings(that is, pictures).

At first, according to the first embodiment of this invention, it applies to tissue manufacturing water of antimicrobial and anti-fungus function in tissue fabric with nano metal particles to guarantee antimicrobial and anti-fungus effects without chemical preservatives or antimicrobial and anti-fungus materials to manufacture wet tissues with raw tissue fabrics which have certain measurement, tensile strength and flexibility.

Hopefully, the Tissue Fabrics applied to the first embodiment of this invention does not limit to only non-woven fabrics of less contamination possibility of bacteria infection caused by external or internal reasons during its manufacturing process, distribution and warehousing but includes also cotton fabrics and pulps.

According to the first embodiment of this invention, the nano metal particles mixed to tissue manufacturing water to have antimicrobial and anti-fungus functions include one or more than one of selected mixtures out of platinum, gold, silver, germanium, selenium and zinc.

Referring to FIG. 1, the nano metal particles applied to this invention to provide antimicrobial and anti-fungus functions, the Platinum (Pt: refer to TEM picture of FIG. 1) has the function of antimicrobial and deodorizer and recognized widely as functional catalyst. In this invention, particle size of 1-50 nm with final concentration level of 0.00001-0.0005 wt % (0.1-5 ppm) of the weight to tissue manufacturing water is used.

The Gold (refer to TEM picture of FIG. 2) out of the above-mentioned nano metal particles have not only antimicrobial function but also inhibitive action against aggregation of nano particles by direct contact, coupling and aggregation. In this invention, particle size of 1-30 nm with final concentration level of 0.00001-0.001 wt % (0.1-l0 ppm) is used.

And, the Silver (refer to FIG. 3, TEM picture and distribution chart) as nano metal particles applied in this invention provides antimicrobial and anti-fungus function and particle size of 1-20 nm with final concentration of 0.0001-0.002wt % (1-20 ppm) to weight of tissue water.

According to this invention, as the nano silver particles may cause color contamination if it reacts to ultra violet light, or it can be aggregated or precipitated if it reacts to remaining sulfides which is used in the manufacturing process of viscose rayon yarn, it is recommended to minimize to use 0.00001-0.002 wt % (0.1-20 ppm).

As the Zinc (refer to FIG. 5, TEM picture) out of nano metal particles applied to this invention shows antimicrobial effect at 30 ppm and anti-fungus effect with above 300 ppm, this invention is using the zinc of 1-5 nm particle size with final concentration of 0.003-0.03 wt % (30-300 ppm) to tissue manufacturing water.

The Germanium (organic germanium: refer to TEM picture of FIG. 6) as nano metal particles were proved through experiment that it has functions of inhibiting increase of spore of mushrooms and fungi.

According to this invention, germanium of 1-50 nm particle size with final concentration of 0.0001-0.01 wt % (1-100 ppm) to weight of tissue manufacturing water is used.

The Selenium (refer to TEM picture of FIG. 7) as nano metal particles applied to this invention has been proved through experiments that it shows antimicrobial effect against spore of fungus bacteria with below 50 ppm.

According to this invention, selenium of 1-50 nm particle size with final concentration of 0.0001-0.01 wt % (1-100 ppm) to the weight of tissue manufacturing water is used.

TABLE 1 Division Pt Au Ag Zn Ge Se H2O2 Application 0.1~5 0.1~10 0.1~20 30~300 1~100 1~100 10~450 Concentration (ppm)

Referring to the table 1, the hydrogen peroxide (H2O2) {circle around (7)} is mixed of into tissue manufacturing water which one or more than one of nano metal particles out of platinum, gold, silver, germanium, selenium and zinc is mixed. Hopefully, mix the hydrogen peroxide to be its concentration 10-450 ppm (0.001-0.045%).

Afterwards, the antimicrobial and anti-fungus yarns are produced by mixing the treat master-batch or compounding chips (3-10% of master-batch chips and 100% of compounding chips) to the raw materials and spin.

In above process, the materials of antimicrobial and anti-fungus {circle around (1)}viscose rayon, {circle around (2)}polyester(PET), {circle around (3)}polyethylene(PE), {circle around (4)}polypropylene(PP), {circle around (5)}cotton and {circle around (6)}pulp which nano metal particles are treated to selectively is used independently or as mixtures of more than one of it. And those are a lied to manufacture textile fabrics (specially non-woven fabrics) that require antimicrobial and anti-fungus functions including wet tissues as an example.

And the total concentration of the nano metal particles used for final raw fabrics of wet tissues is limited not to exceed 0.1 wt % (1,000 ppm to the weight of wet tissue when the nano metal particles of platinum, gold, silver, germanium, selenium, zinc, copper and tungsten independently or mixture of more than one are mixed into above textile materials of {circle around (1)}viscose rayon, {circle around (2)}polyester, {circle around (3)}polyethylene(PE), polypropylene(PP), {circle around (5)}cotton and {circle around (6)}pulp, and the wet tissues manufactured with the textile materials independently or mixtures of more than one of each raw fabric.
