Description
본 발명은 섬유를 코팅하는 장치에 관한 것이다. 더 상세히 설명하면, 본 발명은 은 나노입자를 섬유에 코팅하여 항균기능을 갖도록 하는 은 나노입자 항균 섬유 성막제조 장치에 관한 것이다.The present invention relates to an apparatus for coating fibers. In more detail, the present invention relates to a silver nanoparticles antimicrobial fiber film production apparatus for coating the silver nanoparticles on the fiber to have an antibacterial function.
은(銀)은 650종의 세균과 바이러스를 살균할 수 있는 것으로 알려져 있다. 은이 단세포 병균의 소화나 호흡 등의 신진대사를 도와 주는 효소의 작용을 무력화시켜 병균을 살균하고 방출하는 은 이온(Ag+)이 병균의 생식을 제거하기 때문에 은과 접촉해서 6분 이상 생존할 수 있는 세균은 없는 것으로 알려져 있다.Silver is known to kill 650 bacteria and viruses. Silver ions (Ag + ), which sterilize and release germs by eliminating the action of enzymes that help metabolism, such as digestion and respiration of single cell germs, can survive the germ for more than 6 minutes. It is known that no bacteria exist.
은(銀)은 악취 유발성 세균의 멸균과 곰팡이 방지, 부패방지로 인한 탈취기능이 있다. 세균은 인체 및 생활환경 조건과 유사한 온도인 20℃-35℃, 함수율 50%-70%의 조건에서 매우 빠른 속도로 번식한다. 은 이온은 세균의 증식을 막고 살균을 하여 이로 인해 발생 되는 각종 냄새들을 근본적으로 차단하여 탈취기능을 발휘한다.Silver has a deodorant function due to sterilization of odor-causing bacteria, mold prevention and anti-corruption. Bacteria grow very rapidly at 20 ° C-35 ° C and 50% -70% water content, similar to human and living conditions. Silver ion prevents the growth of bacteria and sterilizes it, and blocks various odors.
은(銀)은 금속물질 특유의 성질로서 지구상의 물질 중 두 번째로 강력한 전자파차폐효과를 가지고 있으며, 나노 입상들이 판막으로 배열되면 광학적인 특성으로 자외선을 차단하여 화장품의 함첨제 등으로 사용된다. 또한, 은 이온(Ag+)은 전기구동장치(텔레비젼, 컴퓨터, 휴대폰 등)내부로부터 발생 되는 음이온(anion)을 중화시키므로써 확실한 대전 방지 기능을 수행한다. Silver (銀) is a unique property of metal materials, and has the second strongest electromagnetic shielding effect among the earth's materials. When nano granules are arranged in a valve, it is used as an additive for cosmetics by blocking ultraviolet rays with optical properties. In addition, silver ions (Ag +) neutralizes anions generated from the inside of electric drive devices (TVs, computers, mobile phones, etc.) to perform a positive antistatic function.
은(銀)은 인체 피부에 접촉했을 때 아무 해를 입히지 않는 반면, 약 650가지 이상의 병원성 유기체를 죽일 수 있다는 것은 이미 의학적으로 입증된 사실이다. While silver does no harm when in contact with human skin, it is already medically proven that it can kill more than 650 pathogenic organisms.
1리터의 물을 소독하는 데는 수백만 분의 1g만 있어도 충분할 정도로 적은 양의 은 입자만 있어도 멸균성이 우수함이 나타나 있다. 최근 약 20 나노미터의 크기의 은 입자를 사용한 제품들이 최근 개발되고 있으며 점점 건강생활 제품으로 향균, 탈취 등의 목적으로 사용되고 있다.Disinfection of 1 liter of water has been shown to be excellent in sterility with only a small amount of silver particles enough to have a million grams of water. Recently, products using silver particles having a size of about 20 nanometers have been recently developed and are increasingly used for the purpose of antibacterial and deodorization as health products.
또한, 나노 크기의 은 함유제품을 생산하는 방법은 여러 가지가 있으나 제조공정이 복잡하고 제조원가가 높다는 것이 단점이다.In addition, there are many methods for producing nano-sized silver-containing products, but the disadvantage is that the manufacturing process is complicated and the manufacturing cost is high.
기존제품들은 고가의 은 나노 파우더나 액상으로 제조한 것을 사용하나 본 기술은 고순도 은 판을 직접 나노 크기의 입자로 진공 플라즈마 속에서 진공 증착하여 섬유류나 기타 플라스틱 제품에 나노 크기를 직접 성막하여 표면의 은 나노가 직접 상기 기능을 최대한 발휘하고 제품과의 접착력을 플라즈마 기술로 증대시키는 것이다. 불순물을 사용하지 않으며 화학적 반응도 필요 없고 고진공하에서 제품에 직접 나노 크기의 은을 성막시키므로 대량제조가 가능하여 섬유나 필름, 유리 등에 나노 제품을 실현하게 할 수 있다. Existing products are made of expensive silver nano powder or liquid phase, but this technology directly deposits high purity silver plate by nano-sized particles in vacuum plasma in vacuum plasma to deposit nano size directly on fibers or other plastic products. The silver nano directly performs the above functions and increases the adhesive force with the product by plasma technology. It does not use impurities and does not require chemical reactions and deposits nano-sized silver directly on the product under high vacuum, enabling mass production to realize nano products in fibers, films, and glass.
그러나, 은 나노 입자를 이용한 제품 제조 공정은 복잡하고 생산 시간이 많이 소요되는 등으로 인해 제품의 제조 원가가 높게 된다는 단점이 있다. 또한, 은나노 입자를 섬유원단 또는 제품에 코팅하는 경우 코팅된 은 나노 입자가 시간이 경과함에 따라 섬유원단 또는 제품으로부터 분리되어 떨어져 나간다는 단점이 있다. However, the manufacturing process using the silver nanoparticles has a disadvantage that the manufacturing cost of the product is high due to the complicated and time-consuming production. In addition, when the silver nanoparticles are coated on the fiber fabric or the product, the coated silver nanoparticles may be separated from the fiber fabric or the product and fall off with time.

(실시예)(Example)
이하, 첨부된 도면을 참고로 하면서 본 발명의 바람직한 실시예를 설명한다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명의 바람직한 실시예에 따른 은 나노 입자 코팅 제조과정을 보여주는 흐름도이다. 1 is a flow chart showing a silver nanoparticle coating process according to a preferred embodiment of the present invention.
도 1에 도시된 바와 같이, 본 발명의 은 나노 입자 코팅 제조 장치는 섬유원단 또는 제품을 건조하기 위한 건조기(20)와, 플라즈마 소오스와 진공증착수단을 구비한 프로세스 챔버(30)로 구성되어 있다. As shown in FIG. 1, the silver nanoparticle coating apparatus of the present invention comprises a dryer 20 for drying a fabric or a product, and a process chamber 30 having a plasma source and vacuum deposition means. .
은 나노입자를 섬유원단 또는 제품(10)에 코팅하기 위한 공정은 다음과 같다. 도 1에 나타나 있듯이, 먼저, 단계 S10에서 건조기(20)를 이용하여 건조 공정을 통하여 섬유원단 또는 제품(10)을 충분히 건조시킨다. 다시 말해, 섬유원단 또는 제품(10)의 건조율은 99.99%이상이 되도록 한다. 섬유원단 또는 제품(10)의 잔여수분을 제거하기 위해 반드시 건조해야 한다. 섬유원단 또는 제품(10)이 충분히 건조되지 않으면(건조율 99.99%이상) 물분자(H2O)가 플라즈마 중에서 분해되어 산소와 은이 결합되어 코팅 효율을 떨어뜨린다는 부정적인 결과를 초래하게 된다.The process for coating the silver nanoparticles on the fabric or product 10 is as follows. As shown in FIG. 1, first, the fiber fabric or the product 10 is sufficiently dried through a drying process using the dryer 20 in step S10. In other words, the drying rate of the fiber fabric or product 10 is 99.99% or more. It must be dried to remove residual moisture from the fabric or product 10. If the fiber fabric or the product 10 is not sufficiently dried (more than 99.99% drying rate), water molecules (H 2 O) are decomposed in the plasma, which results in a negative result that oxygen and silver are combined to reduce the coating efficiency.
이어 건조단계 S20에서는 프로세스 챔버(30)에서 건조된 섬유원단 또는 제품(10)을 장착하고 플라즈마 전처리 공정을 진행하여 건조된 섬유원단 또는 제품(10)이 불순물을 제거하여 건조된 섬유원단 또는 제품(10)에 기공 및 래디컬을 형성한다. 그리고 단계 S30에서는 은 나노 진공증착 수단을 이용하여 은 나노입자를 발생시켜서 건조된 섬유원단 또는 제품(10)의 기공 및 래디컬에 은 나노입자를 코팅시킨다. Subsequently, in the drying step S20, the dried fiber fabric or product 10 is mounted in the process chamber 30 and the plasma pretreatment process is performed to remove the impurities from the dried fiber fabric or product 10 to remove the dried fiber fabric or product ( 10) form pores and radicals. In step S30, the silver nanoparticles are generated by using the silver nano vacuum deposition means to coat the silver nanoparticles on the pores and radicals of the dried fiber fabric or the product 10.
프로세스 챔버(30)의 내부에는 플라즈마 소오스(40)와 진공증착수단(50)을 구비한 코팅 수단(47)이 포함되어 있다. The interior of the process chamber 30 includes a coating means 47 having a plasma source 40 and a vacuum deposition means 50.
도2는 플라즈마 소오스의 구조를 보여주는 도면으로, 플라즈마 소오스(40)는 플라즈마 쉬드(44) 그리고 전원 공급원(46)으로 구성되어 있다. 섬유원단 또는 제품(10)에 플라즈마(41)가 발생되어 섬유원단 또는 제품(10)에 대하여 불순물의 제거와 가공 및 래디컬을 형성시킨다. 2 shows the structure of a plasma source, wherein the plasma source 40 is composed of a plasma sheath 44 and a power source 46. Plasma 41 is generated in the fabric or product 10 to remove impurities, process and radicals on the fabric or product 10.
전원공급원(46)은 음극을 평판금속전극(42)에 걸어주고 양극은 프로세스 챔버(30)에 걸되 접지를 동시에 한다. 이 실시예에서 이용되는 전원 공급원은 직류(DC)뿐 아니라 펄스 전류(Plused DC), 중간 주파수(Middle Frequency), 라디오 주파수(Radio Frequency)전원 중 어느 하나를 사용할 수 있다. The power supply 46 hangs the cathode on the plate metal electrode 42 and the anode hangs on the process chamber 30 while simultaneously grounding. The power supply used in this embodiment may be any one of a pulsed current, a middle frequency, and a radio frequency power as well as a direct current (DC).
전원공급원(46)은 직류전원인 경우 1200V 이상이 플라즈마를 원활하게 발생시키며 전력은 생산속도에 맞춰야 하므로 동일한 전력량으로 30초간 노출할 수 있도록 되어 있다. In the case of the DC power supply, the power supply 46 generates 1200 V or more plasma smoothly, and the power must be adjusted to the production speed so that the power supply 46 can be exposed for the same amount of power for 30 seconds.
가스 공급원(60)으로부터 제공되는 불활성 가스는 예를 들어, 고순도 아르곤, 산소, 질소, 아세틸렌, 공기 등으로 할 수 있으며, 섬유원단 또는 제품(10)의 특성이나 종류에 따라 선택될 수 있다.The inert gas provided from the gas source 60 may be, for example, high purity argon, oxygen, nitrogen, acetylene, air, or the like, and may be selected according to the characteristics or type of the fiber fabric or the product 10.
도 4는 본 발명의 바람직한 실시예에 따른 플라즈마 전처리 공정에 의해 섬유원단 또는 제품에 기공과 래디칼이 형성된 모습의 사진이다. Figure 4 is a photograph of the pores and radicals formed on the fabric or product by the plasma pretreatment process according to a preferred embodiment of the present invention.
본 발명의 바람직한 실시예를 예시하는 도3에 있어서는, 프로세스 챔버(30)의 외부에는 프로세스 챔버(30)의 내부로 소정의 불활성 가스를 공급하는 가스 공급원(60)이 구비되어 있다. 가스 공급원(60)과 프로세스 챔버(30)사이에는 가스 압력을 조절하기 위한 MFC(Mass Flow Controller)용 가스압력밸브(62)가 구비된다. 그리고 진공펌프(64)가 프로세스 챔버(30)에 연결되어 프로세스 챔버(30)의 내부 진공 압력을 조절한다. In FIG. 3 illustrating a preferred embodiment of the present invention, a gas supply source 60 for supplying a predetermined inert gas into the process chamber 30 is provided outside the process chamber 30. A gas pressure valve 62 for a mass flow controller (MFC) is provided between the gas supply source 60 and the process chamber 30 to adjust the gas pressure. In addition, the vacuum pump 64 is connected to the process chamber 30 to regulate the internal vacuum pressure of the process chamber 30.
프로세스 챔버(30)내에서 회전하는 기판(100)에 부착되어 섬유원단 또는 제품(10)을 넣은 후 진공펌프(64, 64')를 사용하여 10-4torr분위기 이하로 만든 후, 10-2torr분위기 때까지 고순도 아르곤 가스를 가스공급원(60)을 통해 투입하여 압력을 유지시킨 후, 2극 금속 평판 전극(42)에 고전압 DC(300~1500V DC)를 걸어 플라즈마를 발생시켜 섬유원단 또는 제품에 래디컬을 형성하여 은 나노 입자가 부착되기 좋은 표면상태를 만든다.Attached to the rotating substrate 100 in the process chamber 30, the fiber fabric or product 10 is put into a 10 -2 torr atmosphere or less using a vacuum pump (64, 64 '), and then 10 -2 The high-purity argon gas is introduced through the gas supply source 60 to maintain the pressure until the torr atmosphere, and then a high voltage DC (300-1500 V DC) is applied to the bipolar metal flat electrode 42 to generate plasma to produce a fiber fabric or a product. Radicals are formed on the surface to make the silver nanoparticles adhere well.
이후, 다시, 5×10-4~5×10-3torr분위기 사이의 압력을 유지하면서 2극 금속평판전극(42)과 은 나노 증발을 위한 진공증착 소오스(50)를 동시에 가동시켜 직선운동하는 증발된 은 입자가 플라즈마 상태에서 회전하는 섬유원단 또는 제품에 코팅되어 스텝 커버러지(step coverage)는 물론 저렴하고 양호한 결과물을 얻는다. 플라즈마와 진공증착에 의해 섬유원단 또는 제품의 기공과 래디컬에 은 나노입자가 코팅된 사진이 도 5에 나타나 있다.After that, while maintaining the pressure between the atmosphere of 5 × 10 -4 ~ 5 × 10 -3 torr, the linear electrode 42 and the vacuum deposition source 50 for evaporation of silver nanoparticles are simultaneously operated to linearly move. The evaporated silver particles are coated on a fabric or article that rotates in the plasma state to obtain step coverage as well as an inexpensive and good result. The photo of silver nanoparticles coated on the pores and radicals of the fiber fabric or the product by plasma and vacuum deposition is shown in FIG. 5.
본 발명은 플라즈마 소오스와 진공 증착 소오스를 포함하는 코팅 장치를 이용하여 섬유원단 또는 제품에 코팅을 함으로써 스텝 커버러지가 좋아져서 저렴하고 양호한 결과물을 얻을 수 있다.According to the present invention, a step coverage is improved by coating a fabric or a product by using a coating apparatus including a plasma source and a vacuum deposition source, thereby obtaining an inexpensive and good result.
