Description

Adsorption cloth for mask with sterilization and deodorization function and mask using the same}

The present invention provides a method for manufacturing an absorbent fabric for a mask having sterilizing and deodorizing functions, and a mask manufactured using the absorbent fabric manufactured by the method.

The sterilizing and deodorizing mask of the present invention can protect the wearer's health by fixing a nano-sized carrier that adsorbs sterilizing and deodorizing ingredients to the mask to filter and purify dust, harmful gases, bacteria, bad odors or moisture contained in the air. In addition, it can be used conveniently and hygienically as it can prevent the spread of germs to others.

In general, masks are widely used by workers working in hospitals or hazardous work environments to prevent harmful substances from being inhaled into the human body through the respiratory tract or to protect the face from extreme cold in the winter.

A mask is an item that covers the nose and mouth to prevent the inhalation or scattering of germs, dust, etc. for health and hygiene purposes. It is usually used to prevent colds, but it is often used to prevent inhaling dust or dust floating in the air, especially When there is a lot of fine dust in the air due to yellow dust, or when air pollution due to automobile exhaust gas is severe, or as in recent cases, the SARS (Acute Severe Respiratory Syndrome: SARS) virus group flies out of the body. Conversely, it is often used to prevent intrusion.

In addition to the original function of such masks, which are simple coverings, many functional masks have been developed recently that not only have a deodorizing function when inhaling polluted air, but also assist in the treatment of respiratory diseases or have antibacterial or fragrance functions.

According to Public Utility Model Publication No. 1999-34474, the front cover of the mask is composed of an inner skin and an outer skin, and an insertion hole is formed in the horizontal direction at the top of the inner skin, and through this insertion hole, the deodorizing layer, antibacterial layer, chemical layer, and fragrance layer are formed. It is designed to insert functional layers such as the like, and can take on each function by replacing the functional layers depending on the surrounding situation.

In addition, Registered Utility Model Publication No. 309,430 describes an aromatherapy device that consists of making an opening on the side or top of a mask made by attaching two pieces of fabric, placing an aromatherapy pad through this opening, and then sealing the opening with a zipper. A mask is introduced.

However, the functional scent of the functional masks does not last long, so it is inconvenient to insert them frequently, and there is a problem that if surrounding contaminants penetrate, it can actually cause hygiene hazards. In addition, conventional masks can protect the respiratory system to some extent from dust contained in the air, but have problems due to bad odors and bacteria generated from moisture in the wearer's breath.

In order to complement this and increase the hygienic function, the present inventor adopted a nano-sized carrier to develop an absorbent cloth and mask with a large area per unit volume, increased moisture absorption effect, and sterilizing and deodorizing functions, and completed the present invention.

The purpose of the present invention is to provide a method of manufacturing an adsorbent cloth for a mask having sterilizing and deodorizing functions using a nano-sized carrier, and a mask manufactured using the manufactured adsorbent cloth.

In order to achieve the above object, the present invention includes the steps of (a) grinding one or more selected from the group consisting of zeolite, CMC, and bentonite individually or in combination to make a nano-sized carrier; (b) When manufacturing and molding fibers, pulp or sponge using cotton fibers, synthetic fibers, or microfibers with good breathability, the above-mentioned carrier is added and molded to produce an absorbent cloth to which the carrier is fixed, or cotton fibers, synthetic fibers, or microfibers with good breathability are manufactured. Applying the carrier to a resin prepared by using the used fiber, pulp, or sponge alone or in a mixture, and then heating to prepare an adsorbent fabric in which the carrier is swollen and fixed; and (c) adsorbing the sterilizing and deodorizing ingredients to the carrier fixed to the absorbent cloth.

In the present invention, the sterilizing ingredient may be cloid silver, and the deodorizing ingredient may be one or more selected from the group consisting of TiO2, cypress extract, and green tea extract.

In the present invention, the amount of the resin used is preferably 2 to 50 parts by weight based on 100 parts by weight of the carrier, and 1 to 10 parts by weight of colloidal silver at a concentration of 10,000 ppm is preferably used based on 100 parts by weight of the nano-sized carrier. It is preferable to use 5 to 50 parts by weight of the deodorizing ingredient dissolved in ethyl alcohol (15% solution) by dissolving green tea extract, cypress extract, or wood vinegar alone or in a mixture, and 5 to 40 parts by weight of TiO2. .

The sterilizing/deodorizing mask using the sterilizing/deodorizing adsorption cloth for masks of the present invention filters and purifies dust, harmful gases, bacteria, bad odors, or moisture contained in the air by fixing a nano-sized carrier that adsorbs sterilizing and deodorizing ingredients, thereby protecting the wearer. Not only can it protect your health, but it can also prevent the spread of germs to others, making it convenient and hygienic to use.

Figure 1 is a diagram showing an absorbent cloth for a mask having a sterilizing and deodorizing function according to the present invention and a mask using the same.

The functions of the carrier and sterilizing and deodorizing ingredients of the present invention are as follows.

Zeolite and bentonite have small, three-dimensional pores and have the ability to absorb odors, but they are also used as a medium to gradually perform chemical functions by adsorbing deodorizing substances or colloidal silver. In addition, zeolite or CMC is a material with fine and numerous pores and is excellent at absorbing moisture or gas, so it is a material that strongly absorbs odors and moisture. If it is pulverized to nano size, the effect is also increased.

Example 1: Preparation of nano-sized carrier

A nano-sized carrier was prepared from one or a mixture of two or more selected from the group consisting of zeolite, carboxymethyl cellulose (CMC), bentonite, and silica by a conventional sol-gel method and grinding method. .

To specifically describe the manufacturing process of nano-sized carriers by the sol-gel method, sol refers to the dispersion of colloid particles less than 1㎛ and is produced from a metal alkoxide solution or hydrous/hydrous metal oxide by a chemical reaction. It can be manufactured using colloidal particles of /anhydrous metal oxide, and as the process progresses, the viscosity of the sol gradually increases to form a gel, so it is called a sol-gel process. Here, gel refers to a three-dimensional polymeric network that forms M-O-M (Metal-oxide-Metal) bonds similar to the bonds found in oxide ceramics.

More specifically, the sol-gel process can be classified into colloidal sol-gel using colloidal particles and polymer sol-gel using organometallic precursors such as metal alkoxide, depending on the raw material, the latter being It's more common. The alkoxide molecule refers to the individual alkoxide used. Under the influence of solvents or other factors, it exists as monomers, dimers, etc., and polymerization occurs due to the hydrolysis reaction and condensation polymerization reaction of metal alkoxide. During polymerization, water added externally acts as an initiator, and acids or bases act as catalysts for these reactions. The initial viscosity of the sol is rather low and in most cases similar to that of water. However, if the condensation polymerization reaction occurs on a significant scale, the sol changes into a gel. When these reactions begin to occur, the metal alkoxide solution begins to transform into a sol. The relatively low molecular weight species present during the initial gelation step are called oligomers.

Example 2: Preparation of adsorption foam with nano-sized carrier fixed to resin

The carrier prepared in Example 1 was added during the manufacturing and molding of fiber, pulp or sponge using cotton fiber, synthetic fiber, or highly breathable microfiber, and then manufactured and molded to prepare an absorbent cloth to which the carrier was fixed. In another method, the carrier is applied to a resin product made by molding cotton fiber, synthetic fiber, fiber using highly breathable microfiber, pulp, or sponge alone or by mixing two or more, and then heating at 180°C for 3 minutes to cause the carrier to swell and adhere. An absorbent cloth was prepared. The amount of resin used in this example was 2 to 50 parts by weight based on 100 parts by weight of the carrier.

When the carrier is applied to the resin surface of a fiber, pulp, or sponge to create a filter cloth, a binder can be used to facilitate adhesion. However, even if a binder is not used, the carrier can be heated at 180°C for 3 minutes using the swelling property of the carrier itself. Adhesion is possible if it is adhered smoothly.

The binder may be selected from vinyl acetate solution, urethane binder, or adhesive used for fiber, pulp, etc., and may be used in the range of 1 to 5 parts by weight based on 100 parts by weight of the carrier.

Example 3: Adsorption of sterilizing and deodorizing ingredients

The sterilizing and deodorizing ingredient was applied to the absorbent cloth prepared in Example 2, and the sterilizing and deodorizing ingredient (3) was adsorbed into the moisture-absorbing pores of the swollen carrier. For 100 parts by weight of nano-sized carrier, 3 parts by weight of colloidal silver at a concentration of 10,000 ppm, 30 parts by weight of deodorizing ingredient dissolved in ethyl alcohol (15% solution) of green tea extract, cypress extract or wood vinegar alone or mixed, and 20 parts by weight of TiO2. Adsorbed.

For the adsorption, the sterilizing and deodorizing ingredients are added to a low-pressure tank, mixed sufficiently, the pH is adjusted to a non-ionic or anionic state, a small amount of less than 3% of the surfactant is administered, and then an adsorbent cloth is administered at 30-50°C. After 3 to 6 hours, the contents were taken out and dried to complete the process.

Colloidal silver, which is absorbed into a carrier for sterilization, has the function of sterilizing 670 types of bacteria and has the function of activating metabolism by silver ions, which is beneficial in creating a residential space for a clean and healthy life.

As deodorizing ingredients, cypress extract and green tea extract, which are absorbed into the carrier, react with odorous substances and change their molecular structure, thereby significantly reducing odors generated from the human body and everyday life.

Figure 1 shows the form of a sterilizing and deodorizing mask according to the present invention, in which a nano-sized carrier (1) is swelled and fixed to the mask (4), and the sterilizing and deodorizing ingredient (3) is placed in the moisture-absorbing pores (2) of the carrier. Adsorption was done to maximize the adsorption area per unit volume.

The sterilizing and deodorizing mask of the present invention uses a nano-sized carrier to have a large area per unit volume, has a good moisture absorption effect, and adsorbs deodorizing ingredients and deodorizing ingredients, making it hygienic and protecting the wearer's health.
