Description
본 발명은 감염 방지성이 우수한 병원 의복용 원단 및 그의 제조방법에 관한 것으로서, 보다 구체적으로는 항균성, 특히 반복 세탁시 항균성이 우수함과 동시에 자외선 차단성 및 소취성이 우수하여 병원내 2차 감염을 효과적으로 예방할 수 있으며, 세탁 후 반복 사용도 가능한 병원 의복용 원단 및 그의 제조방법에 관한 것이다.The present invention relates to a fabric for hospital garments excellent in the prevention of infection and a method of manufacturing the same, more specifically, antimicrobial properties, particularly antimicrobial properties during repeated washing, and at the same time excellent UV protection and deodorant to secondary infection in the hospital The present invention relates to a hospital garment fabric and a method of manufacturing the same, which can be effectively prevented and can be used repeatedly after washing.
본 발명에서는 의사 및 간호사용 가운, 수술복, 환자복 등과 같이 병원 종사자나 환자가 착용하는 모든 종류의 의복을 통칭하여 "병원의복" 이라고 한다.
In the present invention, all kinds of clothes worn by hospital workers or patients, such as doctor and nurse gowns, surgical clothes, and patient clothes, are collectively referred to as "hospital clothes".
종래 병원 의복용 소재로는 부직포나 면직물이 주로 사용되어 왔으나, 상기 종래 소재들은 항균성이 매우 나빠서 병원감염을 일으키는 주요 원인이 되어 왔다.Conventional non-woven fabrics or cotton fabrics have been mainly used as the material for hospital garments, but the conventional materials have been a major cause of hospital infection due to the very bad antimicrobial properties.
병원감염이란 입원당시에는 보이지 않던 감염이 입원 후 또는 퇴원 후에 발생하는 감염증으로 주로 병원성 미생물에 노출되어 발생하게 된다.Hospital infections are infections that were not seen at the time of hospitalization. They are caused by exposure to pathogenic microorganisms.
병원 의복용 소재로 면직물을 사용할 경우 항균성이 떨어지는 문제외에도 발한으로 인한 중량증가로 쾌적성이 저하되는 문제가 있었다.If cotton fabric is used as a material for hospital clothing, there is a problem that the comfort is lowered due to an increase in weight due to sweating in addition to the problem of inferior antibacterial properties.
한편, 병원의복용 소재로 부직포를 사용할 경우 항균성이 떨어지는 문제외에도 가격이 비싸고 1회만 사용이 가능하다는 단점이 있었다.
On the other hand, when using non-woven fabric as a material for hospital clothing, there is a disadvantage that the price is expensive and can be used only once, in addition to the problem of low antibacterial properties.
본 발명에서는 상기의 종래 문제점들을 해결할 수 있도록 자외선 차단성, 항균성 및 소취성이 우수함과 동시에 특히 반복 세탁후 항균성이 우수하여 병원내 2차 감염을 효과적으로 방지할 수 있고, 세탁이 용이하고 세탁 후 반복 사용도 가능한 병원 의복용 원단을 제공하고자 한다.
In the present invention, it is possible to effectively prevent the secondary infection in the hospital because of excellent anti-ultraviolet, antibacterial and deodorant, and in particular excellent antibacterial after repeated washing to solve the above problems, easy to wash and repeat after washing To provide a hospital garment fabric that can be used.
이와 같은 과제를 달성하기 위해서, 본 발명에서는 원단의 표면에 평균직경이 2~5㎚인 은(Ag) 나노입자가 견고하게 광증착된 병원 의복용 원단 및 그의 제조방법을 제공한다.In order to achieve the above object, the present invention provides a hospital garment fabric and a method of manufacturing the same, the silver (Ag) nanoparticles having an average diameter of 2 ~ 5nm on the surface of the fabric firmly photo-deposited.
본 발명에서는 원단 표면에 은(Ag) 나노입자를 견고하게 광증착 시키기 위해서 원단을 구성하는 원사로 (ⅰ) 폴리에스테르 수지로 구성된 코어성분(C)과 (ⅱ) 평균직경이 15~25㎚인 이산화티탄(TiO2)을 3.5~4.5중량% 함유하는 폴리에스테르 수지로 구성된 쉬스성분(S)이 복합 방사된 코어-쉬스형 복합섬유를 사용하여 상기 원사 표면에 분포된 이산화티탄(TiO2)에 은(Ag) 나노입자가 담지되도록 한다.In the present invention, the core component (C) and (ii) an average diameter of 15-25 nm of (i) a polyester resin as a yarn constituting the fabric in order to firmly photo-deposit silver (Ag) nanoparticles on the surface of the fabric to use the sheath-type conjugate fiber of the titanium dioxide is distributed in the yarn surface (TiO 2) - titanium dioxide (TiO 2) the sheath component consisting of a polyester resin containing 3.5 ~ 4.5% by weight (S) is a composite spinning with the core Allow silver (Ag) nanoparticles to be loaded.
또한, 본 발명에서는 상기 원단 표면을 알칼리 수용액으로 감량처리하여 원단 표면에 미세요철을 형성시켜 은(Ag) 나노입자가 원단의 표면에 보다 견고하게 광증착 되도록 한다.
In addition, in the present invention, the surface of the fabric is reduced with an aqueous alkali solution to form fine irregularities on the surface of the fabric so that silver (Ag) nanoparticles are more strongly photo-deposited on the surface of the fabric.
본 발명에 따른 병원 의복용 원단은 자외선 차단성, 항균성 및 소취성이 우수하여, 병원내 2차 감염을 효과적으로 예방할 수 있고, 세탁이 용이하고 반복 세탁 후 사용이 가능하여 의사용 가운, 수술복, 환자복 등의 병원 의복용 원단으로 유용하다.

보다 구체적으로, 본 발명의 병원 의복용 원단을 구성하는 원사는 도 1에 도시된 바와 같이, (ⅰ) 폴리에스테르 수지로 구성된 코어성분(C)과 (ⅱ) 평균직경이 15~25㎚인 이산화티탄(TiO2)을 3.5~4.5중량% 함유하는 폴리에스테르 수지로 구성된 쉬스성분(S)이 복합 방사된 코어-쉬스형 복합섬유이다.More specifically, the yarn constituting the hospital garment fabric of the present invention, as shown in Figure 1, (i) the core component (C) consisting of a polyester resin and (ii) the average diameter of 15 to 25nm A sheath component (S) composed of a polyester resin containing 3.5 to 4.5% by weight of titanium (TiO 2 ) is a composite-spun core-sheath type composite fiber.
도 1은 본 발명에 따른 병원 의복용 원단을 구성하는 원사의 단면 개략도로서, 코어성분(C)은 고유점도(Ⅳ) 0.63 정도의 폴리에스테르 수지로 구성되고, 쉬스성분(S)은 고유점도(Ⅳ) 0.63 정도의 폴리에스테르 수지에 평균직경이 15~25㎚인 이산화티탄(TiO2)이 3.5~4.5중량% 함유된 성분으로 구성된다.1 is a cross-sectional schematic view of the yarn constituting the fabric for hospital clothing according to the present invention, the core component (C) is composed of a polyester resin of about 0.63 intrinsic viscosity (IV), the sheath component (S) is intrinsic viscosity ( ⅳ) 0.63 poly average diameter of the polyester resin consists of approximately 15 ~ 25㎚ of titanium dioxide (TiO 2) a component containing 3.5 ~ 4.5% by weight.
상기 이산화티탄의 평균직경이 15㎚ 미만인 경우에는 은(Ag) 나노입자를 광증착시 은(Ag) 나노입자가 이산화티탄에 견고하게 담지되지 않게 되고, 25㎚를 초과하는 경우에는 쉬스성분(S)내 이산화티탄의 분산성이 저하되는 문제가 발생된다.When the average diameter of the titanium dioxide is less than 15 nm, silver (Ag) nanoparticles are not firmly supported on titanium dioxide when the silver (Ag) nanoparticles are photodeposited, and when it exceeds 25 nm, the sheath component (S) There arises a problem that the dispersibility of titanium dioxide within is lowered.
은(Ag) 나노입자를 병원 의복용 직물에 광증착 시킬 때 은(Ag) 나노입자는 상기 쉬스성분(S)내 이산화티탄(TiO2)에 견고하게 담지된다.When the silver (Ag) nanoparticles are photo-deposited on a hospital garment fabric, the silver (Ag) nanoparticles are firmly supported on titanium dioxide (TiO 2 ) in the sheath component (S).

The dispersibility of titanium dioxide in the component is lowered, resulting in a problem that silver (Ag) nanoparticles are unevenly supported on the surface of the hospital garment fabric when the silver (Ag) nanoparticles are photo-deposited.
