Description
본 발명은 전자파 차폐코어사 및 이를 포함하는 직물에 관한 것이다. 보다 상세하게는 본 발명은 전자파의 차폐를 위해 도전사(導電絲)를 일반 피복섬유로 감싸서 코어얀으로 된 전자파 차폐코어사를 제조하고, 또한 이를 포함하도록 하여 직물을 제조함으로써 전자파 차폐코어사의 도전사에 의해 전자파 차폐 효과가 높은 전자파 차폐직물에 관한 것이다.The present invention relates to an electromagnetic shielding core yarn and a fabric comprising the same. More specifically, the present invention provides an electromagnetic wave shielding core yarn made of core yarn by wrapping the conductive yarn with a general coating fiber for shielding electromagnetic waves, and also fabricating a fabric to include the same to the conductive yarns of the electromagnetic wave shielding core yarn. The present invention relates to an electromagnetic shielding fabric having a high electromagnetic shielding effect.
일반적으로 전자파란 전기장 및 자기장의 변화에 따라 발생하는 방사파를 의미하며, 대부분의 전자제품에서 주로 발생하고 있다. 최근 이러한 전자파의 인체에 대한 유해성이 논란이 되면서 전자파를 차폐할 수 있는 여러 수단들이 강구되기에 이르렀다.In general, electromagnetic waves are radiation waves generated by changes in electric and magnetic fields, and are mainly generated in most electronic products. Recently, as the harmfulness of the electromagnetic wave to the human body has been debated, various means for shielding the electromagnetic wave have been devised.
특히, 전자파는 TV, 컴퓨터, 세탁기, 진공 청소기 등 일상 생활에서 접하는 대형 가전기기들은 말할 것도 없고 핸드폰, 라디오 등 소형 휴대용 전자기기에서도 정도의 차이는 있으나 끊임없이 방출되고 있다. 최근 이러한 전자기기들에 대한 전자파 억제에 대한 규정이 강화되고 있지만 이들 기기로부터 완벽하게 전자파가 방출되지 않게 하기란 사실상 불가능하다. 일 예로 핸드폰 같은 경우에는 그것과 기지국간의 신호를 전자파로 하기 때문에 전자파의 발생은 필수적이다. 그리고 무엇보다도 심각한 문제는 현재 주로 사용되고 있는 대부분의 전자기기들에 대하여 아직 유해성 및 방출기준조차 마련되어 있지 않다는 점이다. 그리고 우리가 일상 생활에서 사용하고 있는 대부분의 가전기기들은 과거의 것들로서 이들에 대하여는 전혀 전자파차폐기능을 기대할 수 없다. 또한 전자파 방출량을 억제한 최근의 제품이라 할지라도 장기간 인체가 노출되면 조사량이 시간에 비례하여 증가하기 때문에 부작용에 대한 문제를 배제할 수 없다고 할 것이다.In particular, electromagnetic waves are constantly being emitted even in small portable electronic devices such as mobile phones and radios, not to mention large home appliances such as TVs, computers, washing machines and vacuum cleaners. In recent years, regulations on electromagnetic wave suppression for such electronic devices have been tightened, but it is virtually impossible to completely prevent electromagnetic waves from being emitted from these devices. For example, in the case of a mobile phone, the generation of electromagnetic waves is essential because the signal between it and the base station is an electromagnetic wave. And above all, the serious problem is that there are no hazard and emission standards for most of the electronic devices currently in use. And most of the home appliances that we use in our daily lives are things of the past and we cannot expect electromagnetic shielding at all. In addition, even the latest products that suppressed the emission of electromagnetic waves, the amount of irradiation increases in proportion to time when the human body is exposed for a long time can not rule out the problem of side effects.
따라서, 일상적으로 사용하는 생활용품 중에서 전자파차폐기능을 갖는 것을 개발하는 것이 바람직하며, 그에 따라 인간생활에서 정상적으로는 항시 착용하고 있는 의복에 전자파차폐기능을 부여하는 기술들이 개발되고 있다.Therefore, it is desirable to develop an electromagnetic wave shielding function among daily necessities of daily use, and accordingly, technologies for providing an electromagnetic wave shielding function to clothes which are normally worn in human life have been developed.
전자파를 차단하는 의복에 사용되는 원사는 도전성을 가져야 하는데, 이 도전성을 부여하기 위해 이용되는 물질로는 은(silver), 동(copper), 알루미늄(aluminium), 탄소섬유(carbon fibre) 등이며, 이들 물질들을 섬유에 첨가하는 방식으로는 금속을 이온화하여 화학적으로 결합시키는 방법이나 무전해도금 방식으로 금속을 섬유의 표면에 부착시키는 방법이나 금속선이나 탄소섬유를 그대로 사용하여 연사, 교직 등의 방법으로 직접 사용하는 방법 등을 들 수 있다.Yarns used in garments that block electromagnetic waves must have conductivity, and the materials used to impart this conductivity are silver, copper, aluminum, and carbon fiber. These materials can be added to fibers by ionizing metals and chemically bonding them, by attaching metals to the surface of the fibers by electroless plating, or by twisting, weaving, etc. using metal wires or carbon fibers as they are. The method of using directly, etc. are mentioned.
그러나, 이러한 종래의 전자파 차단을 위한 원사는 전자파차폐 효과는 있으나, 촉감 등에서 좋지 않다는 단점이 있다. 더욱이 가느다란 금속사나 얇은 금속막을 입힌 전도사는 공기나 물기 등에 노출되면 급속히 산화하고 마모되어 도체로서의 기능이 단시간 내에 상실되는 문제점이 있다. 또한 금속이온의 침적은 도전성이 떨어질 뿐만 아니라 금속염의 수용성 때문에 세탁이나 우천시 노출 등에 의해 물성이 현저히 저하되는 결점이 있다.However, the conventional yarn for blocking electromagnetic waves has an electromagnetic shielding effect, but has a disadvantage in that it is not good in touch. In addition, there is a problem that a thin metal yarn or a conductive film coated with a thin metal film rapidly oxidizes and wears when exposed to air or water, and thus loses its function as a conductor in a short time. In addition, the deposition of metal ions has a drawback that not only the conductivity is lowered but also the physical properties of the metal ions are significantly lowered due to washing or exposure in the rain due to the water solubility of the metal salt.
대한민국 공개특허공보 97-76896호에는 동선을 경사로 하고, 동박선을 위사로 하여 면사로 함께 직조하는 기술이 기재되어 있다. 그러나 이는 동선 및 동박선들이 면사들에 함께 짜여지는 것에 불과해 앞에서 언급한 문제점 외에 촉감 등이 좋지 않고, 동선이 면사들과 일체화되지 않아 직물의 형태안정성이 저하되는 문제점이 있다.Korean Patent Laid-Open Publication No. 97-76896 describes a technique for weaving together a cotton yarn using a copper wire as an incline and a copper foil as a weft. However, this is only copper wire and copper wire is woven together in the cotton yarns, the touch is not good in addition to the above-mentioned problems, there is a problem that the copper wire is not integrated with the cotton yarns, the shape stability of the fabric is lowered.
대한민국 공개특허공보 99-2294호에는 일반사에 동박을 권회시킨 권회사를 기술하고 있으나, 동박을 얇게 하더라도 앞에서 언급한 문제점 외에 일반사에 동박을 권회시키기 때문에 직물에서의 올이 굵어지게 되어 역시 촉감이 좋지 못하다는 문제점이 있다.Korean Patent Laid-Open Publication No. 99-2294 describes a winding company that wound copper foil to a general company, but even though the copper foil is thin, the fabric is rolled up to a general company in addition to the above-mentioned problems, so the fabric is thicker and softer. There is a problem that this is not good.
대한민국 공개특허공보 99-73268호에는 섬유체에 금속염을 침적시키는 기술이, 그리고 대한민국 공개실용신안공보에는 동사를 경사와 위사로 교차적으로 편직한 후, 일반사로 편직된 피복재와 합지시키는 직물이 기술되어 있으나, 이들 역시 상기한 문제점들을 완전히 해결하고 있지는 못하다.Korean Laid-Open Patent Publication No. 99-73268 describes a technique for depositing metal salts on a fiber body, and a Korean Laid-Open Utility Model Publication discloses a fabric in which a verb is cross-knitted with warp and weft, and then laminated with a coating material knitted with general yarn. However, they also do not completely solve the above problems.
본 발명의 목적은 직·편물의 촉감이 좋으며, 또한 전자파차폐 효과가 우수한 직·편물용 전자파 차폐코어사를 제공함을 목적으로 한다.An object of the present invention is to provide a woven / knitted electromagnetic wave shielding core yarn having good tactile feel and excellent electromagnetic shielding effect.

상기 일반 피복섬유는 면, 모, 마, 견, 기타 천연섬유와 나일론, 폴리에스테르, 아크릴, 레이온, 텐셀 등 화학섬유 및 이들의 혼방섬유 들로 이루어지는 그룹 중에서 선택되는 섬유이다.The general coated fiber is a fiber selected from the group consisting of cotton, wool, hemp, silk, other natural fibers and chemical fibers such as nylon, polyester, acrylic, rayon, tencel, and blended fibers thereof.
이하, 본 발명의 구체적인 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 전자파 차폐코어사(13)의 심사를 피복하는 일반섬유원료는 공지의 방법으로 방적공정의 혼타기에 투입하고 공지의 방법으로 소면, 연조 및 조방을 거쳐 도 1의 로우빙을 만들어 로우빙권취롤(11)에 권취시키고, 이 로우빙을 로우빙가이드(7)를 거쳐 백톱로울러(5)와 백보텀로울러(6), 미들톱로울러(3)와 미들보텀로울러(4)를 거쳐 프런트톱로울러(1)와 프런트보텀로울러(2)에 공급하면서 공지의 방법으로 드라프트(DRAFT)하여 플리스(Fleece)상태로 공급한다. 이때 별도로 준비하여 심사권취롤(12)에 권취시킨 도전사(동선)를 제2심사가이드(10)를 거쳐 심사공급로울러(9)에 공급한다. 심사공급로울러(9)와 프런트로울러(1, 2)들 간에는 장력을 조절할 수 있는 장치가 공지의 방법으로 부착되어 있다. 또한, 상기 심사공급로울러(9)와 프런트로울러(1, 2)들 간에는 제1심사가이드(8)가 더 취부될 수 있다. 장력의 조절은 심사공급로울러(9)와 프런트로울러(1, 2)들 간의 표면속도비를 조정함으로써 달성될 수 있으며 1.005내지 1.15사이로 조절하는 것이 바람직하다. 장력이 1.005미만으로 하는 경우 피복율이 좋지 않으며 1.15초과하는 경우 사절이 일어나는 문제점이 있다.The general fiber raw material covering the screening of the electromagnetic wave shielding core yarn 13 according to the present invention is put into the horn of the spinning process by a known method, and made a roving of FIG. 1 through carding, softening, and roughening by a known method. It is wound on the roving winding roll 11, and the roving is passed through the backing guide 7 to the back top roller 5, the back bottom roller 6, the middle top roller 3 and the middle bottom roller 4 After supplying to the front top roller (1) and the front bottom roller (2) through the known method it is drafted (DRAFT) and supplied in a fleece (Fleece) state. At this time, the conductive yarn (copper line) prepared separately and wound on the examination winding roll 12 is supplied to the examination supply roller 9 via the second examination guide 10. Between the screening feed roller 9 and the front rollers 1, 2, a device capable of adjusting the tension is attached in a known manner. In addition, a first screening guide 8 may be further mounted between the screening supply roller 9 and the front rollers 1 and 2. The adjustment of the tension can be achieved by adjusting the surface velocity ratio between the feed feed rollers 9 and the front rollers 1, 2, preferably between 1.005 and 1.15. If the tension is less than 1.005, the coverage is not good, and if it exceeds 1.15, there is a problem that trimming occurs.
상기한 전자파 차폐코어사는 편물 혹은 직물 혹은 기타 용도로 활용될 수 있으며 다양한 의류제품으로 제조할 수 있다. 직물의 경우에는 경사와 위사에 다같이 사용할 수 있으며 전자파 차폐 효과를 최대로 하고 경제적으로 제조하기 위해서는 일반사와 전자파 차폐코어사의 사용비율을 5:1 혹은 8:1등으로 하여 전자파 차폐코어사의 사용량을 절감할 수 있다.The electromagnetic shielding core yarn may be utilized for knitting or woven fabric or other uses, and may be manufactured in various garment products. In the case of woven fabric, it can be used for both warp and weft yarns. In order to maximize the electromagnetic shielding effect and to manufacture economically, use ratio of general shielding yarn and electromagnetic shielding core yarn to 5: 1 or 8: 1, etc. Can be saved.
또한 상기에서 도전사(심사)(14)를 동선으로 언급하고 있으나, 동선 이외에 도전성을 갖는 은사, 금사, 니켈사, 스테인레스사, 탄소섬유의 필라멘트사를 사용할 수 있으며 피복섬유(로우빙)(15)로는 면, 마, 견 기타 천연섬유 및 폴리에스터, 나일론, 폴리프로필렌, 아크릴사, 레이온, 고강력 레이온, 텐셀 등 화학섬유들을 모두 사용가능하며 천연섬유, 화학섬유등의 혼방도 가능하다.In addition, although the conductive yarn (screening) 14 is mentioned as a copper wire in the above, it is possible to use silver, gold, nickel, stainless, carbon fiber filament yarn having conductivity other than copper wire, and coated fiber (roving) 15. Furnace can use all kinds of chemical fibers such as cotton, hemp, silk and other natural fibers and polyester, nylon, polypropylene, acrylic yarn, rayon, high strength rayon, tencel, and blend of natural and chemical fibers.
또한 동선은 잘 구겨지는 현상이 있으므로 동선과 함께 합성섬유 필라멘트를 합연하여 동선 대신 심사로 공급할 수도 있다.In addition, copper wires are wrinkled well, so synthetic fiber filaments may be combined with copper wires to be supplied as a screening instead of copper wires.
또한 로우빙을 만드는 방법도 면방시스템뿐만 아니라 소모시스템에 의하여서도 만들 수 있으며 면 정방기 뿐만 아니라 소모 정방기를 사용할 수 있음은 물론이다.In addition, the method of making the roving can be made not only by the cotton spinning system but also by the consumption system, and of course, the cotton spinning machine can be used as well as the cotton spinning machine.
또한 동선의 인장 강도를 향상시키고 염색성을 부여하기 위하여 가염성 수지를 동선에 피복할 수 있다. 수지는 폴리우레탄(polyurethan), 나이론(nylon), 폴리에스터(polyster)등을 사용한다.In addition, in order to improve the tensile strength of the copper wire and to impart dyeing property, a salty resin may be coated on the copper wire. The resin is polyurethane (polyurethan), nylon (nylon), polyester (polyster) and the like.
실시예 1Example 1
피복섬유를 면(COTTON)으로 하되 통상의 방법으로 면 로우빙을 만들고 심사공급장치를 부착한 정방기의 백 로울러에 공급하여 미들 로울러를 거쳐 프런트 로울러에까지 진행케하고 심사는 별도로 0.03㎜의 동선과 30D(Denior)의 폴리에스터를 통상의 방법으로 합연하여 준비하였다. 이렇게 준비한 심사를 심사공급장치를 이용하여 프런트 로울러에 공급하되 심사 드라프트는 1.08로 하면서 장력을 가하였고 로우빙플리스와 중심을 일치시켰다. 프런트로울러에서 나오는 심사＋로우빙 플리스에 20tpi(twist per inch)의 연수를 가하여 30수를 방적하였다. 이때 정방기의 스핀들 속도는 9,000rpm으로 조정하였다. 이렇게 제조된 원사는 피복율이 좋았다.The coated fiber should be cotton, but in the usual way, make the cotton roving and feed it to the back roller of the spinning machine attached with the screening supply device, and then proceed to the front roller through the middle roller. 30D (Denior) polyester was prepared by joining in a conventional manner. This screening was supplied to the front rollers using the screening feeder, but the screening drift was 1.08, and the tension was applied to match the center of the rowing fleece. 20 tpi (twist per inch) of water was applied to the screening and roving fleece from the front roller, and 30 water was spun. At this time, the spindle speed of the spinning machine was adjusted to 9,000 rpm. The yarn thus produced had a good coverage.
이 원사를 CM 30수와 경사, 위사 공히 11:1로 배열하고 경사 밀도 25.4mm당 98본, 위사밀도 25.4mm당 78본으로 평직을 제직하고 면 쪽만 나염하였다.The yarns were arranged at 11: 1 for both the 30 CM and the warp yarns, and the weft yarns were weaved with 98 weaves per 25.4 mm warp density and 78 weaves per 25.4 mm weft density.
전자파차폐효과는 주파수 200MHZ ∼ 1000MHZ대에서 65 ∼99%의 차폐를 나타내었다. 향균 효과는 99%, 마찰대전압 730V로 좋은 정전방지효과가 있었다.The electromagnetic shielding effect showed a shielding of 65 to 99% in the frequency range of 200 MHz to 1000 MHz. The antibacterial effect was 99% and the frictional voltage was 730V, which showed good antistatic effect.
상기한 실시예를 종합한 결과 본 발명에 따르면 전자파 차폐효과가 우수하고 정전기 발생 방지 및 촉감이나 직물의 반발력 등에서 일반 직물들과 거의 유사하면서 전자파 차폐 효과를 갖는 직물을 수득할 수 있음을 확인할 수 있었다.As a result of synthesizing the above embodiment, it was confirmed that according to the present invention, a fabric having excellent electromagnetic shielding effect and having electromagnetic shielding effect while being almost similar to those of general fabrics in the prevention of static electricity generation and the touch or the repulsive force of the fabric could be obtained. .
따라서, 본 발명에 의하면 직물의 촉감이 좋으며, 또한 전자파차폐 효과가 우수한 전자파 차폐코어사 및 이를 포함하는 전자파 차폐직물을 제공하는 효과가 있다.Therefore, according to the present invention, the feel of the fabric is good, and also has an effect of providing an electromagnetic shielding core yarn having excellent electromagnetic shielding effect and an electromagnetic shielding fabric comprising the same.
