Description

Manufacturing method of antimicrobial blankets with enhanced antibacterial sustainability}

The present invention relates to a method for manufacturing an antibacterial duvet with enhanced antibacterial persistence, and more specifically, to a duvet made of a fabric having antibacterial activity including an antimicrobial material and a far-infrared ray emitting material and having a characteristic capable of maintaining antimicrobial activity even when washed at a high temperature. it's about

As one of the fabrics that come in direct contact with the body, duvets are recognized as important for hygiene. In particular, the skin of infants is vulnerable to pollutants attached to blankets because a barrier against external contaminants is not sufficiently formed, and since infants sleep longer than adults, the hygiene of blankets is recognized as very important. In addition, in the case of baby blankets, they are often boiled and used because they are highly likely to be contaminated with secretions such as sweat or urine.

Antibacterial fabric can be produced by applying a natural extract having antibacterial and antiviral effects to polyester or nylon fibers, as described in Korean Patent Registration Publication No. 10-2249507. In addition, as disclosed in Korean Patent Registration No. 10-1141149, antibacterial components such as silver, selenium, and zinc are mainly used, but germanium, tungsten, silicon dioxide (Silica, silicon dioxide), titanium dioxide (TiO ₂ ; Titanium Dioxide), A far-infrared ray emitting component such as aluminum oxide (Al ₂ O ₃ , aluminum oxide) may be included. If the antibacterial component or far-infrared radiation component is simply treated, it is easily lost during washing, so it is treated with nanoparticles and used for weaving, or weaving using such a thread. Alternatively, synthetic polymer fibers such as polyester or nylon to which an antibacterial component or a far-infrared ray emission component are well combined may be used.

However, this antibacterial blanket can be irritating to the skin of infants, and it is difficult to maintain the bonding strength under the conditions of boiling and using at a high temperature even if a certain level of bonding strength is maintained for the material of the fabric in general washing. In addition, fabrics made of synthetic polymer materials often cause deformation when exposed to high temperatures, and these fabrics also have the disadvantage of easily losing their antibacterial power at high temperatures when simply treated with antibacterial components.

One aspect is one or more first nanoparticles selected from the group consisting of silver, selenium, and zinc, and germanium, tungsten, silicon dioxide (Silica, silicon dioxide), titanium dioxide (TiO ₂ ; Titanium Dioxide), and aluminum oxide (Al ₂ mixing one or more second nanoparticles selected from the group consisting of O ₃ and aluminum oxide;

antibacterial treatment by treating the first nanoparticles and the second nanoparticles with cotton threads;

Obtaining an antibacterial fiber fabric by mixing the antibacterially treated thread and glass fiber; and

It provides a method for manufacturing an antibacterial duvet comprising the step of disposing a cotton fabric on both sides of the antibacterial fiber fabric.

Another aspect provides an antibacterial bedding manufactured by the above manufacturing method.

One aspect is one or more first nanoparticles selected from the group consisting of silver, selenium, and zinc, and germanium, tungsten, silicon dioxide (Silica, silicon dioxide), titanium dioxide (TiO ₂ ; Titanium Dioxide), and aluminum oxide (Al ₂ mixing one or more second nanoparticles selected from the group consisting of O ₃ and aluminum oxide;

antibacterial treatment by treating the first nanoparticles and the second nanoparticles with cotton threads;

Obtaining an antibacterial fiber fabric by mixing the antibacterially treated thread and glass fiber; and

It provides a method for manufacturing an antibacterial duvet comprising the step of disposing a cotton fabric on both sides of the antibacterial fiber fabric.

The first nanoparticle is to provide an antibacterial function to the fabric fabric, and includes one or more materials selected from the group consisting of silver, selenium, and zinc. The second nanoparticles have a far-infrared ray emission function, are intended to further enhance antimicrobial activity, and include at least one material selected from the group consisting of germanium, tungsten, silicon dioxide, titanium dioxide, and aluminum oxide. The size of the first nanoparticle or the second nanoparticle may be 1 nm to 20 nm, 1 nm to 15 nm, or 5 nm to 15 nm. The size of the nanoparticles may be defined as a D50 value as an average diameter of all nanoparticles. If the size of the nanoparticles is larger than the above range, the surface area capable of performing the antibacterial function may be reduced and the function may be reduced.

The first nanoparticles or the second nanoparticles may be 1% to 15% by weight, 1% to 10% by weight, or 3% to 8% by weight based on the weight of the yarn to be treated with antibacterial treatment. The antimicrobial material and the far-infrared ray emitting material are sufficient as long as they can achieve antibacterial activity, and when used in excess of the above range, cost may increase or rash or fabric deformation due to the antibacterial material may occur.

The first nanoparticle and the second nanoparticle may be suspended in a slightly alkaline aqueous solution having a pH of 10 to 12. Specifically, the antibacterial-treated thread is obtained by suspending first nanoparticles and second nanoparticles in water, then immersing the thread in the suspension, reacting the surface of the thread with the first nanoparticles and second nanoparticles, and then drying. it could be

The glass fiber contains 50 to 65% by weight of silicon dioxide (SiO ₂ ), 10 to 20% by weight of aluminum oxide (Al ₂ O ₃ ), 5 to 15% by weight of calcium oxide (CaO), and magnesium oxide (based on the weight of the glass fiber). MgO) 5 to 15% by weight and titanium dioxide 0.1 to 1% by weight may be included. More specifically, the glass fibers include 55 to 60% by weight of silicon dioxide, 12 to 17% by weight of aluminum oxide, 8 to 12% by weight of calcium oxide, 8 to 12% by weight of magnesium oxide, and 0.2 to 0.8% by weight of titanium dioxide. it could be Components of the glass fiber may further include a coupling agent.

The glass fibers include silicon dioxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), calcium oxide (CaO), magnesium oxide (MgO), and titanium dioxide and a coupling agent in an amount of 3 to 6% by weight based on the total weight of the glass fibers. After mixing, it may be obtained by reacting at 200 ° C to 300 ° C and extruding.

The coupling agent may be used for the purpose of increasing the tensile strength of glass fibers, and specifically may be an amino silane-based coupling agent. The amino silane-based coupling agent, for example, the amino silane-based compound is (3-aminopropyl) trimethoxysilane, (3-aminopropyl) triethoxysilane, bis (2-hydroxyethyl) -3-amino Propyl trialkoxysilane, diethylaminomethyltrialkoxysilane, (N,N-diethyl-3-aminopropyl) trialkoxysilane, (2-N-benzylaminoethyl)-3-aminopropyl trialkoxysilane, bis( methyldialkoxysilylpropyl)-N-methyl amine, bis(trialkoxysilylpropyl) urea, bis(3-(trialkoxysilyl)propyl)-ethylenediamine, bis(trialkoxysilylpropyl)amine and bis(trimethoxy) Silylpropyl) may be at least one selected from the group consisting of amines, but is not limited thereto.

In the case of a baby blanket, it is washed several times at a high temperature of 100 ° C. or higher with a surfactant such as detergent for disinfection, and in this process, the antibacterial component may be somewhat lost. Glass fiber is helpful in preventing the antibacterial substance treated on the fabric fabric from being lost even in high-temperature washing.

The glass fiber may have a diameter of 0.1 μm to 10 μm, 0.1 μm to 5 μm, or 0.5 μm to 1.5 μm. Since glass fiber has some tensile strength, if the diameter of the glass fiber is too large, it is difficult to mix and the flexibility of the fabric may be reduced. On the other hand, when the diameter is less than the above, it may be difficult to achieve an antimicrobial maintenance effect.

The glass fiber may be surface-treated to increase interfacial bonding strength, and for example, one selected from amino silane, epoxy silane, amide silane, azide silane, acryl silane, monoalkoxy titanate, zirconate-based binder, etc. What has been surface-treated with the above compound can be used.

The mixing ratio of the antibacterial-treated thread and the glass fiber may be 5 to 8:1 or 7:1 in weight ratio. If the mixing ratio of the antibacterial-treated yarn exceeds the above range, it may be difficult to achieve the antimicrobial maintenance effect by the glass fiber, and if the mixing ratio is less than the above range, the flexibility and heat retention of the fabric may decrease.

The step of obtaining an antibacterial fiber fabric by mixing the antibacterially treated thread and glass fiber may be preferably performed at a high temperature of 45 °C to 65 °C or 45 °C to 55 °C. This is to maintain the flexibility of the glass fiber to increase the binding force with the antibacterial-treated yarn and to improve the weaving efficiency. This contributes to further increasing the antibacterial retention of textile fabrics.

The antibacterial blanket manufactured using the manufacturing method according to one aspect has excellent antibacterial activity while maintaining a soft and cozy touch with pure cotton on both sides.

In addition, since the antibacterial duvet maintains its antibacterial activity even at high temperatures and laundry detergent, it does not lose its antibacterial activity even after being boiled and used several times, and thus has properties suitable for a baby duvet.

Hereinafter, examples will be described in detail to explain the present invention in detail. However, the following examples are only provided to more easily understand the present invention, and the content of the present invention is not limited by the following examples.

Example 1: Manufacturing of an antibacterial bedding

Silver, selenium, and zinc, which are antibacterial components, are mixed in a weight ratio of 1:1:1 and sieved to have a uniform diameter on average. First nanoparticles and germanium, tungsten, silicon dioxide, titanium dioxide, and aluminum Second nanoparticles were prepared by mixing oxides in a weight ratio of 1:1:1:1:1 and sifting through a sieve to form nanoparticles to have a uniform diameter on average. The particles of the nanoparticles had a D50 diameter of 10 nm. The total weight of the first nanoparticles and the second nanoparticles is 5% by weight relative to the weight of the yarn to be treated with antibacterial treatment, and is suspended in slightly alkaline water of about pH 11. After allowing sufficient absorption overnight, the yarn was wound and dried at a high temperature of about 50° C. to obtain an antimicrobial treated yarn.

The glass fiber is a mixture of 59.5% by weight of silicon dioxide, 15% by weight of aluminum oxide, 10% by weight of calcium oxide, 10% by weight of magnesium oxide, and 0.5% by weight of titanium dioxide, and (3-aminopropyl) trimethoxy as a coupling agent. After adding 5% by weight of silane, it was prepared by kneading and extruding at 250 °C. The diameter of the prepared glass fiber was 1 μm.

Then, the antibacterial fiber fabric 100 was woven by mixing the antibacterial yarn and glass fiber at a weight ratio of 7:1. The temperature during weaving was maintained at a high temperature of about 50 °C.

After adding cotton cloth 200 to the upper and lower surfaces of the antibacterial fiber fabric 100 with cotton fabric, filling cotton therebetween, and then quilting, a width * length = 1m * 1m blanket was made.

Comparative Example 1: Manufacturing of a comforter without glass fibers

The quilt was manufactured as in Example 1, but antibacterial fabric was made by weaving with antibacterial-treated yarn and ordinary pure cotton yarn instead of glass fiber. All other conditions were the same.

Comparative Example 2: Change of temperature during weaving

As in Example 1, an antibacterial fiber fabric was made by weaving at room temperature, 15 to 20 ° C, using antibacterially treated yarn and glass fiber. All other conditions were the same.

Comparative Example 3: Change of weaving ratio

As in Example 1, an antibacterial fiber fabric was woven using antibacterially treated yarn and glass fiber, but using the antibacterially treated yarn and glass fiber at a weight ratio of 10:1. All other conditions were the same.

Test Example 1. Antibacterial and antibacterial retention test

Four groups of blankets from Example 1 and Comparative Examples 1 to 3 were prepared, and suspensions of Bacillus cereus and Staphylococcus aureus were applied to each of the two groups of blankets, and 36 3 hours incubation at °C. And the other two groups were put in water containing general laundry detergent, boiled for 3 hours, and dried at high temperature for more than 3 hours, repeating the process 5 times, and then, similarly, bacteria were applied to each group and incubated at 36 ° C. for 3 hours. Then, each blanket was cut into 1 cm ² size, immersed in sterilized purified water, sonicated, and centrifuged. Each sample of the supernatant was dropped dropwise on a 6 mm disc, and the proliferation of bacteria was measured using the disc diffusion method. The average of three repetitions is shown in Tables 1 and 2 below. Table 1 shows the result values for the duvet before boiling, and Table 2 shows the result values for the duvet after boiling.

strain Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 B. cereus 6.13 6.05 6.50 6.15 S. aureus 6.23 6.15 6.85 6.23

strain Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 B. cereus 6.23 8.05 8.60 7.15 S. aureus 6.30 8.15 8.95 7.05

As a result, before boiling, all of Examples 1 to Comparative Examples 1 to 3 maintained antibacterial activity, and Example 1 showed almost similar antibacterial activity compared to Comparative Example 3 containing more antibacterial treatment chambers.

However, after boiling, it was observed that all of Comparative Examples 1 to 3, except for Example 1, greatly lost the antibacterial activity immediately after weaving.
