Description

Manufacturing method of mask and bag fabric with antibacterial, odor and dehumidification functions and Antibacterial masks and antiseptic bags manufactured by the method}

The present invention relates to a method of manufacturing a fabric for a mask and bag to which antibacterial, sterilizing, deodorizing and dehumidifying functions are imparted, and to an antibacterial mask and a sterilizing bag manufactured by the method,

In more detail, antibacterial yarn (PE) and PP yarn with antibacterial function are separated so that they are located on the front and back sides, that is, on the front and back plates, respectively, and the fabric is knitted (weaved). After knitting the basic silk fabric by mixing it in a ratio, mix copper nano and resin (binder) in a certain ratio on the upper surface to dot adhesion, and place an adhesive film with breathability on the upper surface of the dot-adhesive basic yarn fabric. After thermal bonding at a certain temperature, the antibacterial PE yarn part of the knitted (woven) fabric on the upper surface is brought into contact with the adhesive film and heat-processed, resulting in a stable primary outer surface lamination (bonding) process of the woven fabric and the same fabric. The secondary inner part also divides the antibacterial (PE) and PP yarns with antibacterial function so that they are located on the front and back sides, that is, on the front and back plates, respectively. After putting the film on and thermally bonding it at a certain temperature, the PE yarn part, which is the antibacterial yarn of the fabric knitted (woven) on the top surface, is brought into contact with the adhesive film, and final heat processing is performed to make a stable mask and bag fabric,

Through this, the manufacturing method for masks and bags with antibacterial, sterilizing and dehumidifying functions that can be used as a fabric for a mask or a fabric for a sterilization bag that removes harmful bacteria entering the respiratory tract and blocks fine dust Antibacterial masks and sterile bags.

As the industry develops rapidly, the environment is destroyed and the frequency of occurrence of yellow dust and fine dust is increasing.

In particular, fine dust is dust with a particle size of 10 microns or less. Unlike large-diameter dust, fine dust is too small to be filtered through the mucous membrane of the nose and directly penetrates into the lungs, causing respiratory diseases such as bronchitis and asthma. It deteriorates the body's immune function.

In fact, according to the results of many studies, the concentration of fine dust was found to be correlated with early mortality, and for this reason, the World Health Organization (WHO) has designated fine dust as a class 1 carcinogen.

As the number of people active indoors and outdoors increases due to changes in the living environment, exposure to air pollution such as yellow dust and fine dust is becoming more severe. have.

Until recently, in the case of public health masks sold on the market, there were no protection standards against infections, odors, and soot from respiratory diseases.

Currently, in the case of commercially available general masks, most are formed of a single layer of non-woven material, and masks for yellow dust and health care are manufactured and sold by overlapping cotton cloths in 2 to 5 layers, but the fiber diameter of the cotton cloth or fabric used in the mask is As it is composed of several tens of ㎛ grade, there is a limit to completely remove yellow dust or fine particles with a particle size of 1㎛ grade, and it causes suffocation during breathing.

In addition, when wearing a mask, a humid and warm environment is created by coughing, sneezing and breathing. As the wearing time passes, the temperature difference between the inside and the outside becomes larger and condensation occurs. When worn for a long time, the occurrence of off-flavor was inevitable.

Accordingly, the development of filaments and fibers that filter fine dust and have antibacterial and deodorizing functions or water-repellent treatment is being actively conducted.

On the other hand, silver is known to control over 650 kinds of bacteria, viruses, and fungi while being harmless to humans.

Silver attaches to -SH of cysteine, a protein composed of bacteria or viruses, and is converted into a sulfur compound to inhibit reproduction, or attaches to an enzyme that works with oxygen and acts as a catalyst to promote oxidation, sterilizing bacteria, that is, metabolism. It is known as a semi-permanent antibacterial agent that exerts antibacterial activity by acting in a special form on the part involved in the

Silver is applied to filaments and fibers that require antibacterial properties, and the general method to which they are applied is to immerse and coat the filaments and fibers. A method for producing an antibacterial fiber coated with silver nanoparticles, which is characterized by coating silver nanoparticles on a fiber containing an alcohol functional group, using a mixed solution containing a compound, is presented, and Korean Utility Model No. 20-0460479 Ho proposes a mask that has antibacterial and antiviral functions by vacuum deposition or adhesive fixing of silver thread.

However, this simple coating method has problems such as a decrease in the application surface area of the antibacterial material and a problem of detachment and peeling of the coating material.

Recently, there has been a report that silver nanomaterials cannot be discharged when they are introduced into the human body and are harmful because they are not discharged.

It has been confirmed that copper's antibacterial properties have been used for treatment and disinfection purposes since ancient Egypt 2400 years ago.

When copper is oxidized, it takes away oxygen and punctures the virus, completely destroying the nucleic acid, and completely blocking the possibility of mutagenesis by killing the virus.

After all, copper handles are widely used inside and outside hospitals because copper itself can reduce the risk of infection spread without additional antiviral treatment.

In fact, copper was the first metal to be designated as an antibacterial metal by the US Environmental Protection Agency in 2008.

Professor Bill Keevil's research team at the University of Southampton, UK, published a study that copper effectively blocks the transmission of respiratory viruses in the American Journal of Microbiology, mBio, in 2015.

At that time, the study conducted an experiment with the human coronavirus (229E), which is close to SARS and MERS, and confirmed that the virus, which remained infectious for at least 5 days on the surface of a common material, is rapidly destroyed on the copper surface.

In Korea, about 100 door handles were replaced with copper materials in 10 local children's centers.

In addition, in 2012, the US Environmental Protection Agency (EPA) confirmed the fact that more than 99.9% of harmful bacteria were killed on the surface of alloys containing copper within 2 hours, and 355 types of copper alloys including copper and copper were used to remove bacteria. registered as a substance.

On the other hand, antibacterial copper is a fabric coated with copper, and when washed repeatedly, approximately

Antibacterial and deodorizing power is maintained up to 50 to 60 times, and since it is manufactured and supplied by a textile manufacturer, it has the advantage of relatively low cost and easy supply and demand.

Antibacterial copper, which is effective in copper and copper alloy with a copper content of 60% or more, is effective in preventing infectious diseases due to the antibacterial properties of copper itself. It has been reported to relieve pain.

Copper has an oligodynamic effect called micro sterilization and is known to sterilize viruses, microorganisms, and fungi.

As such, antibacterial copper has an antibacterial or antibacterial effect that replaces silver, so it is being applied and used in various forms in daily living facilities.

The present invention was created to solve the above problems,

Antibacterial yarn (PE) and PP yarn with antibacterial function are separated so that they are located on the front and back sides, respectively, and the fabric is knitted (weaved). After knitting the basic silk fabric, mix copper nano and resin (binder) on the upper surface in a certain ratio and dot-adhesive. After bonding, the upper surface of the antibacterial yarn, the PE yarn, of the knitted (woven) fabric is brought into contact with the adhesive film and heat-processed to perform a stable primary outer surface lamination (bonding) process between the woven fabric and the same fabric, 2 The inner part of the car also divides the antibacterial (PE) and PP yarns with antibacterial function so that they are located on the front and back sides, that is, on the front and back plates, respectively. After thermal bonding at a certain temperature, a stable mask and bag fabric is made by final heat processing by bringing the PE yarn part, which is an antibacterial yarn of the fabric knitted (woven) on the upper surface, in contact with the adhesive film,

Through this, the manufacturing method for masks and bags with antibacterial, sterilizing and dehumidifying functions that can be used as a fabric for a mask or a fabric for a sterilization bag that removes harmful bacteria entering the respiratory tract and blocks fine dust It is intended to provide antibacterial masks and sterile bags.

Another object of the present invention is that, when manufacturing a mask using a laminated (bonded) functional antibacterial fabric, the PP yarn constituting the outer surface of the fabric is exposed to the outside when it is attached by sealing it on the inner side of the mask. By doing this, it blocks moisture that can enter the wearer's nose or mouth from the outside while wearing it, and in particular, the pollutant is blocked by the fabric of the company and air flows in only through the ventilation hole, so it is possible to effectively prevent the pollutant from penetrating. The purpose is to effectively sterilize the mask itself while preventing the contaminants and germs (droplets) from coming out of the wearer's nose and mouth from the inside when worn by configuring the side inside.

Another object of the present invention is to block contaminants and to have a very high antibacterial activity because copper powder in the form of microns is nano-sized and distributed in the form of an attachment surface to 85% of the total area excluding vents.

In order to achieve the above object, the present invention proposes a method for manufacturing a mask and a bag fabric to which the following antibacterial and dehumidifying functions are imparted.

The manufacturing method of the fabric for masks and bags with antibacterial and dehumidifying functions of the present invention is

A first process of knitting (weaving) the antibacterial yarn (PE) and the PP yarn to which the antibacterial function is imparted, respectively, to be positioned on the surface and the back surface in a ratio of 50:50;

Knitting a basic verb fabric by mixing antibacterial yarn and verbs in 50:50, 40:60 or 30:70;

forming a dot with an adhesive mixed with copper powder (copper nano) and resin in a ratio of 7: 3 on the upper surface of the basic fabric;

After placing an adhesive film with breathability on the upper surface of the dot-formed basic silk fabric, heat processing at a temperature of 120 to 150° C. is sequentially followed by a second process to obtain a silk fabric;

It consists of a third process of placing the PP fabric obtained in the first process on the upper surface of the same fabric, thermally processing it at a temperature of around 120°C, and laminating it,

At this time, the antibacterial yarn (PE) portion located on one side (surface) of the PP fabric is placed on the upper surface of the adhesive film located on the upper surface of the same fabric.

It is characterized in that the functional antibacterial fabric completed through the third process is cut to have a pattern matching the size or shape of the fabric for a mask or bag, and then sealed with a mask or sterilization bag.

On the other hand, the present invention can be used as desired by using the functional yarn fabric laminated through the first process, the second process, and the third process sequentially as described above, but if necessary, it is added through the third process After inverting the finished functional yarn fabric, put an adhesive film on the other side of the yarn fabric that is laminated but finished in the second process, heat-bonding it at a certain temperature, and then knitting on the upper surface A stable mask and bag fabric is made by adding and including the fourth process, which is completed by final heat processing by bringing the PE yarn part, which is an antibacterial yarn of the (woven) fabric, in contact with the adhesive film.

When manufacturing a mask or pouch-shaped bag using the fabric of the present invention, a process including using a deodorant thread in the sewing line may be added.

In addition to sterilization, it has the characteristic of being able to obtain more deodorizing and deodorizing functions.

The method for manufacturing a mask and bag fabric with antibacterial, deodorizing, and dehumidifying functions according to the present invention can stably perform the role of a filter body such as antibacterial and fine dust as well as the stability of functional antibacterial fabric, and in particular, laminated functionalities When manufacturing a mask using an antibacterial fabric, when attaching it to the inner side of the mask, the PP yarn forming the outer surface of the fabric is exposed to the outside so that it can be introduced into the wearer's nose or mouth when worn. It blocks moisture in advance, and in particular, pollutants are blocked by the fabric and air flows in only through the ventilation holes, so it is possible to effectively prevent the pollutants from penetrating.

This is because the copper powder in the form of microns is nano-sized to block contaminants, and 85% of the total area excluding the vents is distributed in the form of an attachment surface, so it has a very high antibacterial activity. It is clear that this is an excellent and very beneficial invention.

1 is a conceptual diagram showing the concept of a sterilization bag (antibacterial pouch) manufactured by the present invention.

For preferred implementation of the present invention, this will be described in more detail as follows.

[ Step 1] Weaving manufacturing process,

Antibacterial yarn (PE) and PP yarn with antibacterial function are divided into 50:50 on the front and back sides, that is, on the front and back plates, respectively, and the first process of knitting (weaving) is performed.

At this time, since the PP yarn does not contain water and cannot be processed such as adhesion due to the characteristics of the material, since the PE yarn is capable of printing and bonding due to the material characteristics, the PP yarn is placed on the outer surface when the mask or bag is completed, and the antibacterial sign PE is pre-finished for continuous post-processing.

[Second process] Dongbu Corps manufacturing process,

Next, the basic verb fabric is knitted by mixing antibacterial yarn and verb 50:50, 40:60 or 30:70,

This is not the concept of the front plate and the back plate in the first process, but instead of alternating antibacterial yarns and yarns in stripes and weaving them right away.

In the above, when the basic weaving is completed, a step of forming a dot with an adhesive mixed with copper powder (copper nano) and resin in a ratio of 7: 3 is performed on the upper surface;

The dot formation method can be made by engraving and raised by screen printing technique, or can be rolled (copper plate) processing to take a continuous processing form.

In order to prevent detachment because the dot-formed adhesive is attached to the surface of the fabric in a coated form, an adhesive film with breathability is placed on the upper surface of the dot-formed base fabric, and the temperature is 120 to 150 ℃. The second step is to obtain the same fabric by sequentially performing thermal processing at a temperature.

At this time, heat processing means adhesive bonding and prevents the detachment of the dot-formed copper nano, and it is preferable that the air permeability be made in the form of fine holes of about 15% of the total area, and accordingly, the adhesive area is maintained at 85%. , This is because it can stably perform the role of a filter body such as antibacterial and fine dust as well as stability of the fabric.

[3rd process] Department of weaving of the syndicate Lamination process ,

In the second process, when the final fabric to which the adhesive film is attached is completed, the third process of laminating the woven fabric obtained in the first process is placed on the upper surface and heat-processed at a temperature of around 120 ° C.

At this time, the upper surface of the adhesive film located on the upper surface of the same fabric is placed so that the woven fabric, that is, the antibacterial yarn (PE) side part located on one surface (surface) of the PP fabric is in contact with each other.

The heat processing temperature in the lamination process, which is the third process, is to prevent the PP yarn of the woven fabric from being thermally deformed, and the heat processing at this time is the antibacterial yarn of the woven fabric, the PE yarn in contact with the adhesive film, and adhesively fixed. The stable lamination process of the company's fabric is achieved.

It is characterized in that the functional antibacterial fabric completed through the third process is cut to have a pattern matching the size or shape of the fabric for a mask or bag, and then sealed with a mask or sterilization bag.

[4th process] Functional yarn fabric on the other side weaving team lamination process ,

On the other hand, the present invention can be used as desired by using the functional yarn fabric laminated through the first process, the second process, and the third process sequentially as described above, but if necessary, it is added through the third process After inverting the finished functional yarn fabric, put an adhesive film on the other side of the yarn fabric that is laminated but finished in the second process, heat-bonding it at a certain temperature, and then knitting on the upper surface A stable fabric for masks and bags is made by adding and including a fourth process that is completed by final heat processing by bringing the PE yarn part, which is the antibacterial yarn of the (woven) fabric, in contact with the adhesive film.

When used as a mask, the woven fabric is laminated on the inner and outer surfaces of the company's fabric and double-attached to prevent polluted moisture, fine dust, viruses, etc., The PP yarn of the fabric blocks moisture from the wearer's nose and mouth, such as saliva and secretions, so that the antibacterial and sterilization effects of the fabric can be maintained for a long time.

When manufacturing a mask or pouch-shaped bag using the fabric of the present invention, a process including using a deodorant thread in the sewing line may be added.

In addition to sterilization, it has the characteristic of being able to obtain more deodorizing and deodorizing functions.

When manufacturing a mask using laminated functional antibacterial fabric, when attaching it to the inner side of the mask, the PP yarn forming the outer surface of the fabric is exposed to the outside. It blocks moisture that can be introduced in advance, and in particular, pollutants are blocked by the fabric and air flows in only through the ventilation holes, so it is possible to effectively prevent the pollutants from penetrating.

In the end, this means that the blocking of pollutants has a very high antibacterial activity because the copper powder in the form of microns is nano-sized and distributed in the form of an attachment surface to 85% of the total area excluding the ventilation holes.

In this way, when a functional antibacterial fabric is used as a fabric for a mask or bag, it effectively functions as a mask that effectively blocks antibacterial, sterilization, dehumidification and fine dust.

In addition, when manufacturing a mask or pouch-type bag using the fabric of the present invention, a process including using a deodorant thread in the sewing line can be added, which in addition to sterilization, deodorization and deodorization functions can be obtained There are features that can be

The following Tables 1 to 4 are the transcripts obtained by requesting the KOTITI Testing and Research Institute for a bacteria test for the fabric manufactured by the present invention.

In addition, the following Tables 5 to 10 show that the antibacterial mask manufactured according to the present invention was subjected to an antibacterial test at KOTITI Test Research Institute and the results were obtained. It was found that the antibacterial property was very high with a reduction rate of 99.9%.
