Description
본 발명은 전자파 차단 섬유의 제조방법에 관한 것으로, 좀 더 상세하게는 전자파 차단 효과가 있는 게르마늄을 함유한 천연 광석을 셀룰로우즈 아세테이트/아세톤 분산용액에 주입하여 교반시킨 용액에 섬유를 침지시키는 것을 특징으로 하는 전자파 차단 섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing an electromagnetic wave shielding fiber, and more particularly, to infiltrate a fiber in a stirred solution by injecting a natural ore containing germanium having an electromagnetic wave blocking effect into a cellulose acetate / acetone dispersion solution. The present invention relates to a method for producing an electromagnetic wave shielding fiber.
게르마늄은 파장 5.6-15 미크론에 해당하는 복사열이 유해 전자파의 방사 작용과 관련하여 발생된 양전하를 중화시키는 음이온 (OH-)을 제공하여 정전기를 흡수하므로, 유해 전자파는 물론 유해 전자파에 의해 발생되는 정전기를 제거할 수 있다.Germanium is an anion (OH -) to neutralize the positive charge the radiation corresponding to the 5.6 to 15 micron wavelength of the generated radiation in relation to the action of harmful electromagnetic waves caused by the static electricity because the absorption of static electricity, electromagnetic waves are harmful to provide of course harmful electromagnetic waves Can be removed.
게르마늄의 이러한 전자파 차단 기능을 이용하여 다양한 전자파 차단 제품의 연구가 진행되고 있다. 예를 들면, 한국 특허출원 제91-017398호에서는 컴퓨터 오퍼레이터, TV 시청자 및 자동차 운전자 등의 인체보호를 목적으로, 유해전자파 흡수차단기능의 아연 페라이트 혼합물과 인체활성화 기능의 바이오 세라믹 혼합물에 이온 교환기능이 있는 게르마늄 혼합물을 원료로 원형링상이나 판상의 유해 전자파로부터의 인체보호체를 개시하고 있으며, 한국 특허출원 제95-009199호에서는 합성수지 재질 50%에 유기게르마늄, 희토류원소, 바이오세라믹을 50% 화합시켜 제조된 유해전자파 교환기를 개시하고 있다. 또한, 한국 특허출원 제97-023773호에서는 렌즈 기판과 산화물질 사이에 투명한 도전성 피막과 게르마늄을 증착시켜 전자파의 전계를 차단하고, 원적외선을 방사시켜 인체에 유익한 게르마늄 안경 렌즈를 개시하고 있다.Research on various electromagnetic wave blocking products using germanium's electromagnetic wave blocking function is underway. For example, Korean Patent Application No. 91-017398 discloses an ion exchange function for a zinc ferrite mixture with harmful electromagnetic wave absorption and a bio-ceramic mixture with human activation for the purpose of protecting the human body of computer operators, TV viewers and motorists. Using a germanium mixture as a raw material, a human body protector from harmful electromagnetic waves in the form of a circular ring or plate is disclosed. To disclose a harmful electromagnetic wave exchanger. In addition, Korean Patent Application No. 97-023773 discloses a germanium spectacle lens which is beneficial to a human body by blocking an electric field of electromagnetic waves by depositing a transparent conductive film and germanium between a lens substrate and an oxide material and radiating far infrared rays.
한편, 상기와 같이 전자파 차단 기능을 갖는 게르마늄을 섬유에 적용한 예도 있다. 예를 들면, 한국 실용신안 제95-49844호에서는 원유에서 섬유 화합물을 합성하여, 나일론, 폴리에스텔, 아크릴 등의 화합물을 만드는 종합공정에서, 폴리머 상태에서 게르마늄을 5% 상하로 섞고, 별도의 폴리머 상태에서 옥성분을 섞어 각 화합물의 필요한 용융, 습식, 건식 등의 방사공정을 거쳐 얻은 게르마늄을 함유한 기능성 섬유를 발표하였으며, 한국 특허출원 제95-015809호에서는 섬유 원단의 일면에 분말의 상태로 가공한 금, 은, 게르마늄, 세륨을 각각 적정비율(약 25%정도)로 접착제와 혼합한 보호부재를 형성시킨 피부 보호 섬유의 제조방법을 기재하고 있으나, 상기 기술들은 순수 GeO2를 사용함으로써 제조 원가가 높고, 게르마늄을 섬유 제조시 원료에 혼합 사용하면, 섬유의 물성이 변형될 우려가 있으며, 원단에 접착제와 혼합한 보호부재를 사용할 경우, 섬유의 성질 변형 및 세탁시 전자파 차단기능 감소 등이 있을 수 있다.On the other hand, there is an example in which germanium having an electromagnetic wave blocking function as described above is applied to the fiber. For example, in Korean Utility Model No. 95-49844, germanium is mixed up and down by 5% in a polymer state in a synthetic process of synthesizing a fiber compound from crude oil, and producing a compound such as nylon, polyester, and acryl, and using a separate polymer. The functional fiber containing germanium obtained through the spinning process of melting, wet, dry, etc. of each compound by mixing jade in the state is disclosed. Korean Patent Application No. 95-015809 discloses a powdery state on one side of a textile fabric. Described is a method for producing a skin protective fiber in which a protective member is formed by mixing processed gold, silver, germanium, and cerium in an appropriate ratio (about 25%), but the above techniques are prepared by using pure GeO 2 . If the cost is high and germanium is mixed with the raw materials in the manufacture of the fibers, the physical properties of the fibers may be deformed. When the nature of the modified fiber, and washing if there may be reduced such as electromagnetic wave shielding functions.
이에, 본 발명자들은 천연 게르마늄 광석의 미세 입자를 섬유에 코팅하면, 제조 원가가 저렴하며, 평상시의 제품과 다름없이 착용가능하고, 세탁 후에도 영구적으로 유해전자파를 차단할 수 있음을 발견하였고, 본 발명은 이에 기초하여 완성되었다.Accordingly, the present inventors have found that when the fine particles of the natural germanium ore is coated on the fiber, the manufacturing cost is low, and it can be worn as usual, and it can permanently block harmful electromagnetic waves after washing. Completed on this basis.
따라서, 본 발명의 목적은 전자파를 효과적으로 차단하면서, 세탁 후에도 그 기능을 유지시킬 수 있고, 천의 성질을 변화시키지 않으며, 제조 원가가 저렴한 전자파 차단 섬유의 제조방법을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a method for producing an electromagnetic wave shielding fiber which can effectively block electromagnetic waves and maintain its function even after washing, and does not change the properties of the cloth, and has low manufacturing cost.

본 발명은 천연 게르마늄 광석을 이용하여 전자파 차단 섬유를 제조하는 방법을 제공하며, 이를 좀 더 구체적으로 살펴보면 다음과 같다.The present invention provides a method for producing an electromagnetic wave shielding fiber using natural germanium ore, which will be described in more detail as follows.
본 발명에서 사용된 게르마늄 광석은 Cu3(GeFe)S4형 (Germanite형) 게르마늄이 0.36∼1.05% 함유된 천연 광석으로, 하기 표1과 같은 성분을 함유하고 있다.Germanium ore used in the present invention is a natural ore containing 0.36 to 1.05% of Cu 3 (GeFe) S 4 type (Germanite type) germanium, and contains the components shown in Table 1 below.
상기 천연 광석은 1톤당 50만원으로, 1g당 국제가격이 12000원인 순수 GeO2를 사용하였을 경우보다 제조원가를 상당히 낮출 수 있는 장점이 있다. 또한, 상기 성분 중 Cu3(GeFe)S4형 게르마늄은 원적외선을 94% 방사하는 특성이 있다.The natural ore is 500,000 won per ton, there is an advantage that can significantly lower the manufacturing cost than when using a pure GeO 2 international price of 12000 won per 1g. In addition, among the components, Cu 3 (GeFe) S 4 type germanium has a property of emitting 94% of far infrared rays.
상기 광석 중 게르마늄 성분을 섬유에 코팅시키기 위해서는, 먼저 상기 광석을 350∼500메쉬로 분쇄하여 사용한다. 그 후, 상기 분쇄물을 100∼110℃에서 1∼2시간 동안 건조시키는데, 상기 건조 온도가 100℃ 미만이면, 수분이 적게 증발하는 문제가 있고, 110℃를 초과하면, 경제적이지 못한 문제가 있다.In order to coat the germanium component of the ore on the fiber, the ore is first pulverized to 350 to 500 mesh. Thereafter, the pulverized product is dried at 100 to 110 ° C. for 1 to 2 hours. If the drying temperature is less than 100 ° C., there is a problem that the moisture is less evaporated. .
그 후, 상기 건조물은 진공상태에서 냉각되는데, 이는 냉각시 공기를 차단시킴으로써 건조물이 수분을 흡수하지 않도록 하는 효과를 낼 수 있기 때문이다. 다음은 상기 시료를 1∼2% 셀룰로우즈 아세테이트/아세톤 용액에 혼합하고, 40∼50분간 교반시킨다. 상기 셀룰로우즈 아세테이트/아세톤 용액은 셀룰로우즈가 마이크로 캡슐형으로 코팅되는 성질이 있어서, 이를 이용할 경우, 세탁 후에도 게르마늄이 섬유에 부착되어 있어 전자파 차단 기능이 감소되지 않도록 한다. 그러나, 만일 상기 용액의 농도가 1% 미만이면, 게르마늄이 섬유에서 쉽게 탈착되는 문제가 있고, 2%를 초과하면, 전자파 차단 효과가 감소되는 문제가 있다.Thereafter, the dry matter is cooled in a vacuum state, because it can block the air during cooling, which can have the effect of preventing the dry matter from absorbing moisture. Next, the sample is mixed with a 1-2% cellulose acetate / acetone solution and stirred for 40-50 minutes. The cellulose acetate / acetone solution has a property that the cellulose is coated in a microcapsule type, and when used, germanium is attached to the fiber even after washing so that the electromagnetic wave blocking function is not reduced. However, if the concentration of the solution is less than 1%, there is a problem that the germanium is easily desorbed from the fiber, if it exceeds 2%, there is a problem that the electromagnetic wave blocking effect is reduced.
이렇게 교반, 분산된 용액을 아세톤의 휘발을 막기 위하여 10∼20분간 공기차단 상태에서 정치시킨 다음, 섬유를 상온에서 상기 용액에 30∼60분간 교반하여 침지시킨 후, 공기중에서 건조시키면 전자파 차단 섬유를 얻을 수 있다.The stirred and dispersed solution is left to stand for 10-20 minutes in an air-blocking state to prevent volatilization of acetone, and the fibers are stirred and immersed in the solution for 30 to 60 minutes at room temperature, and then dried in air. You can get it.
이하, 실시예를 통하여 본 발명을 좀 더 구체적으로 살펴보지만, 하기 예에 본 발명의 범주가 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited to the following Examples.
실시예Example
0.6% 게르마늄을 함유한 천연 광석을 400메쉬로 분쇄한 후, 상기 분쇄물을 110℃에서 1시간 동안 건조시키고, 상기 건조물을 진공상태에서 냉각시킨 후, 상기 시료를 하기 표 2와 같은 농도의 셀룰로우즈 아세테이트/아세톤 용액에 혼합하고 40분간 교반시켰다. 상기 교반액을 20분간 공기차단 상태에서 정치시키고, 섬유를 상기 용액에 상온 (25℃)에서 40분간 교반하여 침지시킨 후, 공기중에서 건조시켰다. 이렇게 제조된 각각의 섬유에 대하여 전자파 차단여부를 측정하여 하기 표에 나타내었다.After grinding the natural ore containing 0.6% germanium to 400 mesh, the pulverized product was dried at 110 ℃ for 1 hour, the dried material was cooled in a vacuum, and then the sample was subjected to the cellulite concentration shown in Table 2 below. It was mixed with a low acetate / acetone solution and stirred for 40 minutes. The stirring solution was allowed to stand for 20 minutes in an air-blocking state, and the fibers were stirred and immersed in the solution at room temperature (25 ° C.) for 40 minutes, and then dried in air. Each of the fibers thus prepared was measured in the electromagnetic wave blocking and shown in the following table.
한편, 세탁 전,후의 전자파 차단기능을 비교하여 보면, 세탁 후에도 여전히 차단 효과가 있음을 알 수 있다. 그러나, 6개월 이상 계속하여 세탁하면 전자파 차단 효과가 없어진다.On the other hand, comparing the electromagnetic wave blocking function before and after washing, it can be seen that there is still a blocking effect after washing. However, if the washing continues for more than six months, the electromagnetic wave blocking effect is lost.
상기에서 살펴본 바와 같이, 본 발명의 방법에 의해 제조된 전자파 차단 섬유는 효과적으로 전자파를 차단할 뿐만 아니라, 세탁 후에도 그 기능을 유지할 수 있으며, 섬유의 성질을 변화시키지 않고, 제조 원가가 저렴하여 산업적으로 매우 유용하다.As described above, the electromagnetic wave shielding fiber produced by the method of the present invention not only effectively blocks the electromagnetic wave, but also maintains its function after washing, and does not change the properties of the fiber, and the manufacturing cost is very low industrially. useful.
