본 발명은 부직포나 벽지 등 포 형태의 섬유제품에 나노(nano) 스케일의 은 콜로이드 용액으로 처리하여 항균성이 우수한 섬유제품을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a fiber product having excellent antimicrobial properties by treating the fabric of the fabric form such as non-woven fabric or wallpaper with a nano-scale silver colloid solution.

최근 수십 년간 환경오염이 심해지면서 쾌적성을 위해 섬유제품에 항균성을 부여하려는 노력이 진행되어 왔다.In recent decades, as environmental pollution has increased, efforts have been made to give antimicrobial properties to textile products for comfort.

항균가공의 초창기에 항균제는 크게 방향족 할로겐 화합물, 유기실리콘 제4급 암모늄염 및 기타 화합물로 나누어서 사용하였으나, 항균가공의 분야가 확대됨 에 따라서 최근에는 다양한 항균방취제가 개발되고 있다. 그 중에서 가장 일반적으로 사용되고 있는 것은 금속 또는 금속을 함유하고있는 무기물 입자, 제4급 암모늄염 및 유기실리콘 제4급 암모늄염이다. 최근에는 키틴 및 키토산도 적극적으로 사용되고 있다. In the early days of antimicrobial processing, antimicrobial agents were largely divided into aromatic halogen compounds, organosilicon quaternary ammonium salts, and other compounds. However, as the field of antimicrobial processing expands, various antibacterial deodorants have recently been developed. The most commonly used among them are metal or inorganic particles containing metal, quaternary ammonium salts and organosilicon quaternary ammonium salts. Recently, chitin and chitosan have also been actively used.

이와 같은 금속이온이나 제4급 암모늄염에 따른 항균 및 살균작용은 섬유표면에 형성된 항균작용기에 미생물이 직접 접촉되어 이루어지는 것으로, 세포벽이 대전되어 있는 미생물이 금속이온이나 제4급 암모늄의 양이온과 전기적으로 결합되어, 세포기능인 전자전달계가 저하되고 이로 인해 세포막이나 세포벽이 파괴, 제거되어 미생물이 사멸하고, 증식이 억제되는 것이다.The antimicrobial and bactericidal action of the metal ions or quaternary ammonium salts is caused by the direct contact of microorganisms to the antibacterial functional groups formed on the fiber surface. When combined, the electron transfer system, which is a cellular function, is degraded, which destroys and removes cell membranes and cell walls, kills microorganisms, and inhibits proliferation.

그러나, 일부의 방향족 할로겐 화합물은 안전성에 문제가 있어 현재는 사용하지 않고 있고, 과거 금속이온이나 금속을 이용한 항균가공법은 그 항균약제의 경제성이나 섬유에 처리시 가공상의 어려운 점이 있었다.However, some of the aromatic halogen compounds are not used at present because of safety problems, and in the past, antimicrobial processing methods using metal ions and metals had economical advantages of the antimicrobial drugs and processing difficulties in processing fibers.

본 발명의 과제는 이러한 문제점을 해결하기 위해 안출한 것으로서, 본 발명의 목적은 부직포나 벽지 등에 항균력이 우수한 1-300nm 크기의 나노 은 콜로이드 용액으로 처리하여 종래의 섬유제품 보다 우수한 항균성을 갖는 섬유제품을 제공하기 위한 것이다.An object of the present invention is to solve the above problems, the object of the present invention is to treat a non-woven fabric or wallpaper with a nano silver colloidal solution of 1-300nm size with excellent antibacterial activity, textile products having superior antimicrobial properties than conventional textile products It is to provide.

본 발명자는 부직포에 항균력을 갖는 나노 은 콜로이드 용액으로 처리를 한 후 항균효과가 뛰어난 부직포를 얻을 수 있음을 확인하였다.The present inventors confirmed that the nonwoven fabric having excellent antibacterial effect can be obtained after treatment with a nano silver colloidal solution having antibacterial activity on the nonwoven fabric.

약 5000∼50000ppm정도의 나노 은 콜로이드 용액을 픽업률과 필요에 따라 5∼5000ppm정도로 증류수로 희석하여 사용하였다. 이 때 사용되는 은 콜로이드는 그 평균입자의 크기가 약 1∼300nm인 순도 90% 이상인 나노 은 콜로이드 입자이다.About 5000-50000 ppm of nano silver colloidal solution was used after dilution with distilled water at a pickup rate and about 5-5000 ppm as needed. The silver colloid used at this time is nano silver colloidal particles having a purity of 90% or more with an average particle size of about 1 to 300 nm.

일반적으로 항균가공은 섬유제품에 물리화학적 성질을 변화시키지 않고 미생물에 대한 성질을 개량하여 섬유상의 세균이나 곰팡이 등의 서식이나 번식을 억제시킴으로써 인체보호와 위생적인 생활환경을 도모하기 위한 가공을 일컫는다.In general, antimicrobial processing refers to processing to improve human health and sanitary living environment by improving the properties of microorganisms without altering the physicochemical properties of the textile products, thereby inhibiting the growth or reproduction of fibrous bacteria or fungi.

본 발명에서는 항균효과를 부여하는 방법으로 무기금속물인 나노 은 콜로이드 용액을 사용하고 있다.In the present invention, a nano silver colloidal solution, which is an inorganic metal, is used as a method of providing an antimicrobial effect.

은은 예로부터 은식기 등을 통하여 독이나 세균에 대한 항성이 있는 것으로 인식되어 있으며, 단세포 동물 (박테리아, 바이러스, 진균류 등)이 산소 및 소화 대사 작용을 하는 특수한 효소에 작용하여 무력화시키므로써 균들을 질식 또는 아사하게 하는 촉매작용을 하는 것으로 알려져 있다.Silver has long been known to be resistant to poisons and bacteria through silverware and suffocates germs by activating a single cell animal (bacteria, virus, fungi, etc.) acting on a specific enzyme that acts on oxygen and digestive metabolism. It is known to catalyze assa.

은이온은 전기적 충격에 의해 대부분의 병균 세포의 원형질이나 세포분열이 일어나는 생식기관을 파괴하는 것으로 알려져 있다. 따라서 세균, 곰팡이, 효모 등의 증식을 억제하며, 이외에도 은가공 의류제품의 경우 원적외선의 방사와 전방열성이 우수하여 단열·보온 소재로서 여름에는 청량감을, 겨울에는 보온 효과까지 나타낸다고 연구 보고된 바 있다.Silver ions are known to destroy the reproductive organs in which most pathogenic cells of the pathogen or cell division are caused by electrical shock. Therefore, it has been reported that it suppresses the growth of bacteria, mold, yeast, etc. In addition, silver-processed clothing products have excellent radiation and forward heat radiation of far-infrared rays. .

또한 은입자는 극도로 미세하여 체내로부터 쉽게 배출되고 축적되지 않으므로 인체에 대한 안정성도 우수한 것으로 밝혀 진 바 있다. 그러므로 단정적으로 은은 무독성이며 부작용이 없는 최고의 천연항생제라고 할 수 있다.In addition, since silver particles are extremely fine and are not easily discharged and accumulated from the body, they have been found to have excellent stability to the human body. Therefore, silver is arguably the best natural antibiotic without side effects.

위와 같은 특징을 지닌 나노 은 콜로이드 용액은 [도 1] 에 도시된 바와 같이 처리하여 사용하여 줌으로써 항균가공 처리된 제품을 얻을 수 있도록 하였다.The nano silver colloidal solution having the above characteristics was treated as shown in FIG. 1 to be used to obtain an antimicrobial processed product.

실시되는 본 발명에 따른 항균가공처리법은 처리하고자 하는 부직포를 준비한 후, 나노 은 콜로이드 용액을 처리하여 항균가공제가 적정 두께로 도포되어지도록 하고 그 후에 건조 공정을 거치도록 함으로써 항균처리된 제품을 얻을 수 있도록 하였다.The antimicrobial treatment method according to the present invention is carried out by preparing a nonwoven fabric to be treated, the nano-silver colloidal solution is treated so that the antimicrobial agent is applied to the appropriate thickness and then subjected to a drying process to obtain an antimicrobial treated product. It was made.

상기 항균가공제가 처리된 제품은 40∼120℃에서 30초∼15분간 예비건조를 실시토록하되, 급속한 고온건조에 의하여 포의 표면 또는 특정부분에 수지이동(Migration)을 일으키지 않도록 비교적 저온에서 균일하게 가공물의 함수율 20∼25% 정도까지 건조할 목적으로 행하는 것이 바람직하다. 이와 같이 예비건조한 후 100∼170℃의 온도에서 1∼10분간 본 건조를 실시하는데, 이때 건조기의 폭방향으로 온도차가 크지 않도록 유지시켜 주는 것이 바람직하다.The product treated with the antimicrobial treatment agent may be pre-dried at 40 to 120 ° C. for 30 seconds to 15 minutes, but uniformly at a relatively low temperature so as not to cause resin migration on the surface or a specific portion of the fabric by rapid high temperature drying. It is preferable to carry out for the purpose of drying to about 20-25% of the moisture content of a workpiece | work. After this preliminary drying is carried out for 1 to 10 minutes at a temperature of 100 ~ 170 ℃, it is preferable to keep the temperature difference in the width direction of the dryer so as not to be large.
