Description

(Antibacterial Fabrics Using Polyester Crops and Their Manufacturing Method)

The present invention relates to an antimicrobial antimicrobial fabric using a polyester raw material and a method for producing the antimicrobial antimicrobial fabric, and more particularly, to a method for producing an antimicrobial antimicrobial fabric using polyester raw material, Which is excellent in fastness and low in flame retardancy and has excellent antimicrobial and anti-bacterial properties, and a method for producing the same.

There are many kinds of fungi and fungi that cause harmful effects on the human body, such as the deterioration of fabrics or nonwoven fabrics, the generation of odor, Or non-woven fabric.

As such, our environment is susceptible to contamination by various microorganisms such as bacteria and fungi. Therefore, in order to prevent embrittlement of fiber materials and to lead a healthy and comfortable life as much as possible, Recently, according to social environment changes that emphasize the importance of public hygiene by improving the standard of living of consumers and pursuing a pleasant life, it is now possible to provide various products such as antifouling, antibacterial and anti- Demand for functional fiber products has increased significantly.

In particular, the improved economic power is a factor that greatly increases consumers' interest in health. It is also known as one of the causes of atopy and has been given the antimicrobial function to suppress the insect pests such as house dust mites and mosquitoes, Interest in functional fibers has been greatly increased.

However, in spite of the above-mentioned high interest of consumers, development of a fiber product having excellent functionality such as antibacterial property, anti-bacterial property, anti-brittleness property while maintaining excellent durability remains as a problem of solving the safety problem of fiber.

That is, conventionally, in order to impart antimicrobial activity for suppressing the generation of insect pests such as house dust mite to the fiber product, an organic phosphorus pesticide or a pyrethroid insecticide is diluted in an organic solvent, or an emulsifier is prepared as a water- However, such insecticides are problematic for human health.

In particular, various types of petroleum-based solvents used as antibacterial components such as iothiazolin and various petroleum-based solvents used as binders are excellent in short-term antimicrobial effect, but have a bad influence on the human body during long-term use, The antimicrobial and insecticidal effect is not maintained for a long period of time because the aromatic natural product is a volatile substance.

In order to overcome the above-mentioned conventional problems, research and development of an antibacterial and antifungal fabric and a manufacturing method thereof have been actively carried out. Representative conventional technologies will be described as follows.

Korean Patent Registration No. 10-0769852 discloses that 50 to 85 parts by weight of glycol ether as a solvent, 2 to 10 parts by weight of pyrethrin or cinerin as a repellent extract as an insecticide, 0.8 to 2 parts by weight of an esterification catalyst 5 to 20 parts by weight of isothiazoline as an antibacterial agent and 2 to 8 parts by weight of an interface-inactive component, and a fiber processing method using the composition.

The above-mentioned prior arts provide chemical insecticide and antimicrobial property with low toxicity to human body, induce chemical bonding through esterification reaction between -OH group of fibrous tissue and -COOR group of pinene and cinerine, The composition of the prior art has durability only when the -OH group is present in the fiber. However, since the type of fiber in which the -OH group is present is limited, it can be applied to only some fibers, Since the -COOR group of the threonine and cinerine binds to the -OH group of the glycol ether as the solvent, the esterification reaction of the -COOR group of the pinethine and the cinerine, which are insect control components, with the -OH group of the fiber is insufficient, There are disadvantages.

Korean Patent Laid-Open Publication No. 10-2005-0100587 discloses that 0.1 to 10 parts by weight of triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) is used as an antimicrobial agent, A fiber coating composition having microencapsulation technology having 0.1 to 40 parts by weight of at least one selected from the group consisting of antiseptics, anethole, citronella, di lemon, geraniol, citral, nerol and eucalyptus And 30 parts by weight of the fiber coating composition, and 70 parts by weight of an aqueous acrylic resin as a binder for fibers at a ratio of 1:12 with respect to water to coat the fibers so as to improve the antimicrobial function and the persistence of the insect-repellent function However, since the microcapsule composition of the prior art has a weak binding force with fibers, the microcapsule composition is easily detached from the fibers during washing, so that the antibacterial and insect repellent effect is temporarily exerted. As a capsule film, one or two kinds of synthetic resins such as polyurethane, polyvinyl alcohol, epoxy, acrylic resin and natural materials such as gelatin, agar, gum Arabic and chitosan are selected to form a primary or secondary capsule film. The antimicrobial and insecticidal components can not be diverted to the outside, so that the antimicrobial and insecticidal effect can not be provided substantially.

On the other hand, since fatal diseases are mainly caused by damage to human organs caused by physiological infections, medical personnel such as nurses, doctors, physiotherapists and medical personnel who are mainly involved in the disease or potentially possessing the patient, It is inevitable to develop an antimicrobial antimicrobial fabric and a manufacturing method thereof for producing a medical suit, a glove, and a bedding having excellent antimicrobial properties in order to prevent such secondary infection.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the structure and action of the antimicrobial textile fabric using the polyester raw material of the present invention and the manufacturing method thereof will be described in detail with reference to the accompanying drawings.

A method for fabricating an antimicrobial anti-fouling fabric using the polyester yarn of the present invention includes: a fabric preparation step (S10) of weaving a fabric 10 using a polyester original yarn and a fusion yarn; A first water-repellent step (S20) of impregnating and drying the raw fabric (10) with a pretreatment agent to form a first water-repellent layer (20) on the surface of the raw fabric (10); A second water-repellent step (S30) for impregnating the pretreated fabric (10) with a post-treatment agent to perform secondary processing; A drying step of thermally fixing the second water repellent treated fabric (10); A calendering step (S40) of calendering the thermally fixed fabric (10); A coating process (S50) of applying and coating a coating composition on one side of the calendered fabric (10); And a cutting step (S60) of cutting the fabric (10) dried on the surface of the antibacterial coating layer (40) according to a product standard.

The fabric preparation step S10 is a step of weaving the fabric 10 using a combination of a primary yarn and a fused yarn and is a process of weaving a yarn of 180 inches in width with a width of 50 inches made of polyester of 85 denier, To form a fused yarn of 50 denier, and then a warp yarn is weighed so as to obtain a warp yarn having a warp width of 4500 inches and a density of 4800 in a cannon, and the warp yarns are weighed from the right side to the left side A raw material of 80 to 95% by weight of a polyester chip, 1 to 4% by weight of a color master batch and 4 to 16% by weight of an antimicrobial master batch is melted and melted at a temperature higher than the melting point, The fabric 10 is manufactured by a weaving method in which three yarns of polyester yarn formed by extrusion and cooling through dunes are weighed.

The polyester chips preferably have an intrinsic viscosity (IV) of 0.6 to 0.9. If the intrinsic viscosity is less than 0.6, the fiber formation is poor and a large number of hollows are difficult to be formed inside, which will be described later. When the intrinsic viscosity is more than 0.9, the melt viscosity increases. The intrinsic viscosity can be calculated by the well-known Bill Meyer approximation after measuring the flow time of the polyester / solvent solution versus the flow time of the pure solvent through the standard capillary as an auto-viscometer.

The color masterbatch is added for coloring the polyester to be mixed with a dispersant and a colorant such as carbon black. The color master batch is preferably 1 wt% to 4 wt% based on the total weight of the polyester-based synthetic resin chips mixed. When the color masterbatch is less than 1% by weight, color development is difficult. When the color masterbatch is more than 4% by weight, there is no effect of color development, and carbon acts as a foreign substance,

As the dispersing agent, a plasticizer for a polyester-type PVC having a molecular weight of 1,500 to 3,000 with respect to a coloring agent such as carbon black is mixed in a ratio of 3 to 20 times by weight and stirred for 10 to 30 minutes at room temperature or heating (60 to 80 ° C) After mixing and dispersing, it is added to the spinning process.

When the molecular weight of the plasticizer for polyester type PVC is 1,500 or less, the viscosity decreases and the acid value increases. When the molecular weight exceeds 3,000, the dispersion state becomes poor.

When the pigment is used in an amount less than 3 times, the dispersing effect is lowered. When the pigment is used more than 20 times, the viscosity is lowered and the acid value is increased.

Since the plasticizer for polyester type PVC used herein is a resin system such as polyester resin, it is not only good in compatibility in melt mixing, but also can solve problems such as migration and pyrolysis because it is a polyester having a molecular weight of 1,500 to 3,000, Since the pigments of large particles are melted and formed into fine particles of the pigments during the stirring, they are evenly dispersed in the polyester, so that not only the dye migration can be prevented even in the heat treatment and other processing steps, .

The antimicrobial substance of the antimicrobial masterbatch is formed by mixing an antimicrobial substance selected from the group consisting of nano silver colloid, zirconium, inorganic ceramic and copper-based antimicrobial agent with the chemical resin chip at the same ratio and drying.

It is possible to selectively apply various mixing methods well known in the technical field of the present invention to the method of mixing the antibacterial substance and the chemical resin chip. However, in order to improve the efficiency of the manufacturing process, a drum type drying apparatus capable of simultaneously drying alcohol as a solvent in the mixing process is used. In order to prevent the antimicrobial substance from adhering to the drying vessel, the inside of the drying vessel is lined with Teflon resin .

The antimicrobial substance is preferably a powder having a particle size of 300 to 400 nm. If the particle size is too large, uniform kneading is difficult and the physical properties of the yarn can be lowered. If the particle size is too small, This is because the cost increases. As a method of pulverizing the antimicrobial substance, a known manufacturing method such as mechanical pulverization using mechanical force is used.

The drying temperature after the mixing of the antibacterial substance and the chemical resin chip is preferably 80 ° C or less. If the drying temperature is high, the antimicrobial substance may be oxidized in the air and the physical properties may deteriorate. Further, when the drying apparatus is depressurized, the production efficiency of the antibacterial master batch is improved.

If the concentration of the antimicrobial substance is too low, the mixing and manufacturing process takes a long time and the amount of the solvent to be lost during the drying is high, which causes a cost increase and a working environment is also deteriorated. Conversely, if the concentration is too high, it is difficult to produce a uniform concentration of the antimicrobial master batch.

Since the polyester yarn yarn has antimicrobial, anti-fogging and anti-brittleness properties by using the antibacterial masterbatch, the fabric 10 obtained through the weaving of the yarn yarn and the fusing yarn itself has antimicrobial, anti-fogging and anti-brittleness properties.

And a warp density per inch in the upper weft weaving step is 95T and a weft density per inch in the upper weft yarn step is 70T, .

In addition, the warp and the weft are woven in a manner of weaving the weft yarn in the warp yarn without warping the warp yarns and the weft yarns, respectively, so that the weft yarn and the weft yarns are separately processed, It is possible to prevent the deformation of the fabric (10) by being able to withstand the heat when ironing, and also to prevent the deformation of the fabric (10) before the frequent water washing or dry cleaning The raw material of the polyester base yarn has a functional masterbatch which has an antibacterial function and a seaweed function, so that the fabric 10, which is woven by constituting the functional masterbatch, has antibacterial, antiperspirant, antioxidant And the like.

On the other hand, the original yarn formed through melting and spinning of the target material can be maximized in terms of coloring or color representation due to the production method due to the spinning process. This is because the pigment, which is not a production method through dyeing or processing using a dye ≪ / RTI >

Further, after the weaving, if necessary, the fabric 10 can be further dyed. In this configuration, not only the color possessed by the original yarn but also the fabric 10 woven with the original yarn and the fused yarn are dyed, So as to enable sharp and differentiated color implementation.

That is, in the present invention, in addition to the color representation of the original yarn, another color process is performed on the finished fabric 10 by using the original yarn, so that when the fabric 10 is expanded and contracted, Or in a state where the fabric 10 is not stretched or shrunk, the color adopted in the dyeing step of the cloth 10 is expressed to the outside, and it is possible to realize a variety of colors with different degrees of sharpness of colors.

Meanwhile, in the fabric preparation step (S10), in order to further enhance the antimicrobial antimony functionality of the fabric, the polyester precursor formed by extruding and cooling through a spinneret is immersed in an electroplating bath to perform electroplating through a silver plating solution , And the electroplated raw material is dried in a drying chamber provided at the rear end of the electroplating bath to form a silver yarn, and the silver yarn and the fused yarn are weaved to form the raw material 10.

In the case where the fused yarn is formed as a silver paste as described above, the electroplating in the electroplating bath is a known electroplating. The silver plating solution contains at least one compound of titanium, selenium and tellurium as a brightener, It is preferable to use an electrolytic silver plating solution using a cyanide containing a lysine or benzooxazole type gloss control agent.

In the electroplating, a current is supplied through a generator using a typical plating vessel containing a silver plating solution. When the power is turned on, a negative electrode rod connected to a material to be plated is negatively charged. The electrons emitted from the anode rod are transferred to silver ions to precipitate silver atoms, and the precipitated silver atoms are adsorbed on the surface of the cathode, thereby plating the material to be plated by a known electroplating method.

As described above, in the fabric preparation step (S10), the polyester yarn using the antibacterial master batch is plated with silver, which is widely known as an antibacterial material, to form a silver yarn, and then the yarn is woven with a fusion yarn to produce a fabric. The beauty is greatly doubled.

In the first water-repellent step S20, the prepared fabric 10 is dipped in a first water-washing tank with a pretreatment agent to form a first water-repellent layer 20 on both sides of the woven fabric 10, And mangles at a pickup rate of 50 to 60%, and then dried at a temperature of 200 to 220 DEG C and at a treatment speed of 30 to 40 m / min through a tenter. The composition of the pretreatment agent is as follows.

- Pretreatment preparation -

▷ Water: 500ℓ

? Super water repellent agent: 1 to 3 parts by weight

Water repellent penetration agent: 0.1 to 0.3 part by weight

Antibacterial antifungal agent: 1 to 3 parts by weight

If the pick-up rate is less than 50%, the cloth 10 immersed in the pretreatment composition as described above is woven into the mangle at a pick-up rate of 50 to 60%. If the pick- The antibacterial property of the fabric 10 is difficult to exhibit due to the reduced amount of the agent applied, and when it exceeds 60%, the yellowing of the color and the production cost increase and the handle becomes rough.

On the other hand, when the fabric 10 is dried and heat-treated at a temperature lower than 200 ° C, it is difficult to achieve a good quality coating due to insufficient drying, and the adhesion of the antibacterial anti- If the hot air temperature exceeds 220 ° C, the fabric 10 may be thermally dried due to excessive drying, so that the feel of the fabric 10 may become hard. Therefore, in the first water repellent step S20, It is very important to set the temperature at 200 to 220 ° C.

The second water-repellent step S30 is performed to form the second water-repellent layer 30 on the outer side of the first water-repellent layer 20 formed on both sides of the fabric 10 through the first water- The fabric 10 is impregnated with a post-treatment agent in a second spatula and then woven with a mangle at a pick-up rate of 50 to 60%, and then heated at a temperature of 200 to 220 ° C and a treatment rate of 40 to 50 m / And dried. The composition of the post-treatment agent is as follows.

- Post treatment composition -

▷ Water: 500ℓ

? Super water repellent agent: 1 to 5 parts by weight

Water repellent penetrating agent: 0.1 to 0.5 parts by weight

Antibacterial antifungal agent: 1 to 5 parts by weight

The process of controlling the pick-up rate using the mungle and drying the fabric 10 using the tenter in the second water-repellent process (S30) are the same as those described in the first water-repellent process (S20).

On the other hand, after the drying of the raw fabric 10 by the tenter machine is completed in the second water-repellent step S30, the raw fabric 10 can be dried in the tumbling tumbler to forcefully shrink in the warp and weft directions.

In this case, the forced contraction is performed by moving the temperature of the space for 5 minutes staying through the three cylinders having the surface temperature of 130 DEG C to 140 DEG C in an electromagnetically held tumbler, and thereafter deforming by upwards, downwards, do.

The calendering step S40 is a step in which the smoothness of the surface of the fabric 10 for forming a uniform antibacterial coating layer 40 before forming the antibacterial coating layer 40 on both sides of the fabric 10 after the second water- at a temperature of 150 to 180 DEG C, a nip pressure of 80 to 100 kgf / cm < 2 >, and a treatment rate of 30 to 40 m / min to impart planarization.

If the temperature of the calendering is less than 150 ° C, the smoothness of the fabric 10 is lowered to cause deterioration of the coating quality. If the calendering temperature exceeds 180 ° C, the temperature of the fabric 10 Causes a change in color and texture

When the nip pressure is less than 80 kgf / cm < 2 >, it is difficult to impart proper tensile force to the fabric 10, so that uneven calendering occurs and the nip pressure exceeds 100 kgf / , Deformation of the shape of the raw material 10 may be caused by heat drying by excessive pressing.

In addition, if the processing speed is less than 30 m / min, the production efficiency is lowered. If the processing speed exceeds 40 m / min, uneven calendering may occur due to excessive processing speed.

The main components included in the pretreatment agent and the post-treatment agent used in the first water-repellent step (S20) and the second water-repellent step (S30) are as follows.

The super water repellent agent is excellent in water resistance and water repellency by using a fluorine-based water repellent agent which is an eco-friendly substance that does not contain a polyoxyethylene alkyl phenol adduct and maintains the inherent tactile sensation of the fabric 10, Strength is excellent. The composition of the super water repellent agent is as follows.

- Super water repellent composition -

Water: 55 to 65 wt%

▷ Fluorine-based polymer: 20 to 30 wt%

Tripropylene glycol: 5 to 15 wt%

Polyoxyethylene: 5 to 10 wt%

The pH of the super water repellent agent is about 4-6. In order to maximize the water repellency effect, the pH of the first and second water-repellent baths should be maintained between at least 3-7, and if it exceeds 8, a small amount of acetic acid should be added.

If the water-repellent agent is used in an amount of less than 1 part by weight, the resulting water-resistant and water-repellent effect of the raw material 10 may be significantly deteriorated. On the other hand, There may be a problem that it causes an undesirable result in the appearance of mechanical properties, touch and the like.

The water-repellent penetrating agent promotes the penetration of the water-repellent agent or the like and accelerates the cross-linking to the fiber. It is preferable to use volatile alcohol-based or higher fatty acid amide-modified amine, and the water- Firstly add and dissolve thoroughly, then add super water repellent.

The super water-repellent agent and the water-repellent penetrating agent are widely used in the technical field of the present invention, and those skilled in the art will be able to selectively purchase and use commercially available products.

The antibacterial and antifungal agent mixes and forms at least one or more components of Zinc pyrithione or Thiabendazole, which are known to be free from harmfulness or side effects.

Zinc Pyrithione or Thiabendazole is an antibacterial and antifungal agent that inhibits both fungi (bacteria) and bacteria (bacteria), and has a known side effect such as skin irritation It is used as a raw material for shampoo and other materials. It is proven to be safe for human. It is resistant to ultraviolet rays because it does not decompose into acids and alkalis and inhibits the growth and growth of fungi. Thiabendazole, Is a very safe substance that is also approved as a food additive in Japan and the United States.

On the other hand, it includes polypropylene glycol which is used as an inert ingredient, a polyurethane, a rheology modifier, an interface inert component and the like when a mixture of zinc pyrite-on and thiabendazole is mixed. Composition of antimicrobial agent is as follows.

- Antimicrobial anti-bacterial composition -

Zinc Pyrithione: 10 to 20 wt%

Thiabendazole: 10 to 20 wt%

Inert ingredients: 0.5 to 4 wt%

▷ Polypropylene Glycol: 60 to 78 wt%

Examples of the antimicrobial antimicrobial agent include inorganic antimicrobial substances such as metals such as silver, copper and zinc or metals such as silver, copper and zinc which are supported on an inorganic material, and inorganic antimicrobial substances such as CAS (Chemical Abstracts Service) and EPA Among the registered chemicals, 2-Pyridiothiol-1-oxide sodium salt, N, N-dimethyl-N'-phenyl- (N'-fluoro-dichloromethyl-thiol N'-fluoro-dichloromethyl-thio) -sulfoamide, diiodomethyl-PtolylSulfone, isopropylmethylphenol, Any antimicrobial antifungal agent conventionally used in the art having antimicrobial and / or anti-inflammatory properties such as organic antimicrobial substances such as methylisothiazolinone or methyldibromo glutaronitrile may be used. However, it is preferable to use inorganic and / It is preferably used as the organic anti-microbial substance, and the amount of use thereof is preferably used in 1 to 5 parts by weight, based on the total weight of the antibacterial coating composition.

The coating step S50 is a step of forming an antibacterial coating layer 40 using a coating composition on one side of the calendered raw fabric 10 by using a coating material on the surface of the raw fabric 10, The coating material is applied to the surface of the fabric 10 by the progress of the fabric 10 in a state of being directly in contact with the surface of the fabric 10 and the surface of the coating material thus coated is scraped with a knife to uniformly adjust the thickness of the coating material, An antimicrobial coating layer 40 of 5 to 10 g / gsm is formed on both sides of the fabric 10.

The coating method may be selected from various coating methods such as a knife coating method, but not limited thereto, an over roll coating method, a spray coating method, and the like.

However, in the coating method, a resin, an emulsion, a dispersing agent or the like dissolved and dispersed by using an organic solvent and water such as the knife coating is applied to the surface of the fiber, and the solvent is vaporized by heat and bar, Unlike the dry coating method in which the island surface is coated with a solid coating, it is coated with a coating solution which is compatible with water and completely dissolved in an organic solvent such as alcohol or dimethylformamide, followed by immersion in a large amount of water A wet coating method can form a volume cross-sectional layer because micro-pores are formed in the cross-section of the coating layer. However, such large pores are not formed in the fibers Since it is formed in the coating layer, it is desorbed by friction or washing and durability is lowered, so that the wet coating is preferable Not the place turns in advance.

The composition of the coating composition is as follows.

- Coating Composition -

Catalyst: 0.5 to 1.5 parts by weight

Antibacterial antifungal agent: 1 to 5 parts by weight

That is, the coating composition is prepared by mixing 0.5 to 1.5 parts by weight of a catalyst and 1 to 5 parts by weight of an antimicrobial anti-fouling agent with 100 parts by weight of a polyurethane resin, stirring the mixture, and filtering through an 80 mesh filter.

As described above, the fabric 10 coated with the coating agent on the surface is passed through the heat chamber at a temperature of 150 to 180 ° C and a processing speed of 30 to 40 m / min to dry the antibacterial coating layer 40 on the surface of the fabric 10, When the temperature of the heat chamber is in the range of 150 to 160 ° C, the residence time of the heat chamber is set to about 3 minutes. When the temperature of the heat chamber is in the range of 160 to 170 ° C, the residence time of the heat chamber is set to about 2 minutes. The retention time of the heat chamber is preferably about 1 minute or less.

Adjusting the residence time in accordance with the temperature setting of the heat chamber as described above is for imparting optimum film forming properties to both surfaces of the fabric 10. [ For example, when the drying is not performed in accordance with the appropriate temperature and the appropriate time, it is difficult to form a strong antimicrobial coating layer 40 and the washing ability is remarkably lowered. Thus, the antimicrobial coating layer 40 is formed by frequent water washing, This is easily damaged.

The polyurethane resin constituting the coating composition may be prepared by charging a prepolymer produced by the reaction of a diisocyanate and a polyol in a reactor and then adding a copolymerized ionomer of an alkyl aryl ethylene oxide and an alkyl aryl propylene oxide to the reactor, And then ethylene glycol (EG) and propylene glycol (PG) were added in succession to completely dissolve. Thereafter, distilled water was added thereto and the temperature was raised from 50 to 60 ° C at pH 5.0 to 6.0. Thereafter, Based urethane crosslinking agent having an isocyanate group and a non-silicone-based defoaming agent while completely maintaining the temperature at 4,000 to 5,000 rpm and then completely dissolving the solution and cooling the reactor temperature to 20 to 30 캜.

The prepolymer may be used in an amount of 80 to 100 parts by weight, the copolymerized ionomer of alkyl aryl ethylene oxide and alkyl aryl propylene oxide may be used in an amount of 10 to 30 parts by weight, ethylene glycol (EG) may be used in an amount of 1 to 10 parts by weight, propylene glycol (PG) 1 to 10 parts by weight of distilled water, 70 to 100 parts by weight of distilled water and 1 to 7 parts by weight of triclosan.

The crosslinking agent may be selected from the group consisting of isocyanate group-containing toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), polymeric diphenylmethane diisocyanate (MDI), tolylidine diisocyanate (TODI) or aromatic isocyanate such as p-phenylene diisocyanate, or at least one of hexamethylene diisocyanate (HMDI) and hydrogenated diphenylmethane diisocyanate (MDI) Are mixed and used.

The crosslinking agent crosslinks the surface of the fabric 10 without applying or adhering the water repellent to the surface of the fabric 10 so that the water repellent agent adheres more firmly to the fabric 10 and can be used for external interference such as frequent water washing or dry cleaning The water repellent agent is imparted with durability so as not to be easily damaged.

The above-mentioned antifoaming agents may be silicon-based and non-silicon-based antifoaming agents, but it is preferable to use non-silicone antifoaming agents. Such antifoaming agents can be understood to be well known to those skilled in the art so that they can be easily purchased and used commercially. The defoaming agent defoins and defoins bubbles, particularly bubbles in a polyurethane dispersion coated on the surface of the substrate, to remove bubbles and pinholes of a size of several tens of microns or more on the coated surface of the final fabric 10.

When the antifoaming agent is used in an amount of less than 1 part by weight, bubbles and pinholes are formed in the antimicrobial coating layer 40 and the surface of the antifungal coating layer 40 due to deterioration of antifoaming action. On the other hand, , And the surface of the fabric 10 may be unevenly formed

The catalyst may be a tin-free catalyst, for example, zinc N-ethyl-N-phenyl dithiocarbamate, cyclohexylamine acetate, It is selected from bi trichloride, stannous octoate, zirconium octoate, zinc nitrate, barium nitrate and lead stearate. .

In the present invention, the coating step (S50) is performed only once. However, if necessary, the antibacterial coating layer (40) may be formed in multiple layers by repeating the coating step (S50) It is preferable that the repetition of the coating process (S50) does not exceed 3 times in order to minimize the change in hue and texture of the fabric 10.

The cutting step S60 may be performed by cutting the edge of the fabric 10 in accordance with the product standard while the fabric 10 dried on the surface of the antibacterial coating layer 40 is transported at a processing speed of 10 to 30 m / Production of the finished product is completed.

The antimicrobial anti-fungal fabric fabricated by the method of producing the antimicrobial anti-fungal fabric using the polyester fiber of the present invention as described above has the laminated structure of the first water repellent layer 20 and the second water repellent layer 30 on both sides of the fabric 10 And the antimicrobial coating layer 40 is integrally formed on the outer side of the second water-repellent layer 30.
