이하 첨부된 도면을 참조하며 본 발명의 꼬임형 형광색사를 실시 예에 따라 자세히 설명하면 다음과 같다.Hereinafter, the twisted fluorescent color yarn of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 꼬임형 형광색사의 구조를 나타낸 사시도 이다.1 is a perspective view showing the structure of the twisted fluorescent color yarn of the present invention.

본 발명의 꼬임형 형광색사는 자외선 조사 시 발광하는 각각 10 내지 30 데니아의 미세굵기를 갖는 다수의 형광색사가 결합한 연사뭉치(10)로 구성되며, 구체적으로 자외선 조사시 적색으로 발광하는 적색형광색사(11)와, 녹색으로 발광하는 녹색형광색사(12)와, 청색으로 발광하는 청색형광색사(13)를 균일하게 꼬아서 하나의 연사뭉치(10)를 형성한 후 절단한다.The twisted fluorescent color yarn of the present invention is composed of a bundle of yarns 10 combined with a plurality of fluorescent color yarns each having a fine thickness of 10 to 30 denier, each of which emits light upon ultraviolet irradiation, and specifically, a red fluorescent color yarn that emits red light upon irradiation with ultraviolet rays (11). ), The green fluorescence yarn 12 emitting green light, and the blue fluorescence yarn 13 emitting blue light are uniformly twisted to form a single bundle of yarns 10 and then cut.

상기 꼬임형 형광색사를 은행권, 유가증권, 신분증 등과 같은 보안용지 제조시 지료에 혼합하는 과정에서 꼬임 풀림을 방지하는 것과 동시에 용지와의 접착도를 증가시키기 위해 적당하게 접착제를 연사뭉치(10)에 도포하는 것이 바람직하다.In the process of mixing the twisted fluorescent color yarn in the manufacture of security paper, such as banknotes, securities, identification cards, etc., in order to prevent the untwisting and at the same time increase the adhesiveness with the paper to the bundle of yarn 10 It is preferable to apply.

상기와 같이 제작된 연사뭉치(10)를 보안용지(20)에 투입하기 위하여 3 내지 10mm 길이로 절단하게 되며, 절단된 연사뭉치(10)에 자외선 조사시 중앙 부위는 삼색 혼합 발광에 따른 백색을 나타내며, 가장자리는 삼색 발광이 각각 나타나는 꼬임형 형광색사를 제조할 수 있다.In order to insert the yarn bundle 10 produced as described above into the security paper 20, it is cut to a length of 3 to 10mm, and when the ultraviolet ray is irradiated to the cut yarn bundle 10, the central portion is white according to tricolor mixed light emission. At the edges, twisted fluorescent yarns in which tricolor light emission occurs may be produced.

이는 꼬임형 형광색사에 자외선 조사시 각각의 적색, 녹색, 청색 형광색사에서 나타나는 적색, 녹색, 청색 광은 곧 빛의 삼원색이기 때문에 이들이 혼합되어 백색으로 보이는 것이며, 이러한 빛의 원리를 이용하여 기존의 형광색사에서는 얻을 수 없었던 특별한 효과를 얻을 수 있게 되는 것이다.This is because the red, green, and blue light emitted from each of the red, green, and blue fluorescence yarns when irradiated with twisted fluorescent yarns are the three primary colors of light, so they are mixed and appear white. It is possible to obtain a special effect that could not be obtained in the fluorescent color yarn.

도 4는 본 발명의 꼬임형 형광색사가 적용된 보안용지를 나타낸 사시도로써 꼬임형 형광색사를 보안용지(20)에 투입한 모습을 나타낸다. 4 is a perspective view showing a security paper to which the twisted fluorescent color yarn of the present invention is applied, showing a state in which the twisted fluorescent color yarn is inserted into the security paper 20.

이와 같이 하여 제조된 형광색사를 지료에 혼합하여 공지의 방법으로 초지하 여 보안용지를 제조함으로써 진위 식별이 용이한 보안 제품을 제공할 수 있다.The fluorescent color yarn prepared in this way can be mixed with a paper stock to produce a security paper by papermaking by a known method, thereby providing a security product that can easily identify the authenticity.

본 발명의 꼬임형 형광색사의 제조방법은 10 내지 30 데니아의 미세굵기를 갖고 자외선에 반응하여 각각 적색, 녹색, 청색으로 발광하는 적색형광색사(11), 녹색형광색사(12), 청색형광색사(13)를 꼬아서 하나의 연사뭉치(10)를 형성시키고 이에 접착제를 도포하여 초지공정에서의 풀림 방지 및 용지와의 접착도를 향상시킨다.The twisted fluorescent yarn manufacturing method of the present invention has a fine thickness of 10 to 30 denier, red fluorescence yarn 11, green fluorescence yarn 12, blue fluorescence yarn (12) which emit red, green, and blue light in response to ultraviolet rays, respectively ( Twisting 13) to form a single bundle of yarns 10 and to apply an adhesive to it to prevent loosening in the papermaking process and improve the adhesion to the paper.

도 2는 새끼꼼 형태로 제작된 연사뭉치를 나타낸 사시도, 도 3은 댕기형으로 제작된 연사뭉치를 나타낸 사시도이다.Figure 2 is a perspective view showing a twisted yarn made in the form of cubs, Figure 3 is a perspective view showing a twisted yarn made in a dendrite shape.

상기 도 2 또는 도 3과 같이 꼬여진 연사뭉치(10)를 3 내지 10mm 길이로 절단하면 빛의 삼원색 혼합에 의해 백색으로 보이는 중앙 부분과 적색, 녹색, 청색이 각각 나타나는 가장자리 부분으로 구성된 특수한 형광색사가 구현된다.When the twisted yarn bundle 10 as shown in FIG. 2 or 3 is cut to a length of 3 to 10 mm, a special fluorescent color yarn composed of a central portion that appears white and an edge portion where red, green, and blue appear, respectively, by mixing three primary colors of light. Is implemented.

도 4에 나타내 보인 바와 같이, 이렇게 제조된 꼬임형 형광색사를 용지 제조과정에 투입하면 진위식별을 위해 자외선 조사 시 형광색사의 중앙 부위에서는 빛의 삼원색의 혼합에 따른 백색이 발광 되고 가장자리 부분에서는 적색, 녹색, 청색이 각각 나타나는 보안성 높은 보안용지를 제조할 수 있다.As shown in FIG. 4, when the twisted fluorescent yarns thus prepared are put into a paper manufacturing process, white light is emitted at the central portion of the fluorescent yarns by mixing three primary colors of light during ultraviolet irradiation for authenticity and red at the edges. It is possible to manufacture high-security security paper in which green and blue appear respectively.

이에 따라 본 발명을 위조하기 위해서는 백색 형광물질을 제조해야 하며 이를 인쇄방식에 모방한다 하더라도 적색, 녹색, 청색의 형광인쇄를 추가로 적용해야 하기 때문에 위변조 난이도가 상당히 높아지며, 정확하게 정위치 맞춤 인쇄를 해야 하기 때문에 위조의 난이도를 극대화할 수 있게 된다.Accordingly, in order to forge the present invention, a white fluorescent material should be manufactured, and even if the printing method is imitated, red, green, and blue fluorescent prints should be additionally applied, and thus the degree of forgery and difficulty is significantly increased. Because it is possible to maximize the difficulty of forgery.

상기와 같은 형광색사의 혼합 발광에 따른 특수한 보안 효과는 단지 적색, 녹색, 청색의 조합에 한정되지 않는다. 산업계에서 사용되는 일반적인 형광색사는 적색, 녹색, 청색뿐만 아니라 노란색 및 주황색 등도 있으므로 이들을 조합하면 매우 특이한 색상을 얻을 수 있게 된다.The special security effect according to the mixed light emission of the fluorescent color yarn as described above is not limited to the combination of red, green and blue. Common fluorescent colors used in the industry are red, green, and blue as well as yellow and orange, so combinations of these can give very unusual colors.

따라서 본 발명에서 제시한 꼬임형 형광색사는 형광색사의 조합에서 얻을 수 있는 대표적인 예를 제시한 것이며, 조합 색상의 종류에 따라 얻을 수 있는 다양한 특수 효과는 본 발명의 범위에 포함되는 것이라 할 수 있다.Therefore, the twisted fluorescent color yarn presented in the present invention is a representative example that can be obtained from the combination of the fluorescent color yarn, various special effects obtained according to the type of the combination color can be said to be included in the scope of the present invention.

본 발명의 꼬임형 형광색사는 은행권, 유가증권, 여권, 주민등록증 등 다양한 보안 문서에 적용되어 그 진위 여부를 간편하게 확인할 수 있으므로 위변조방지 및 범죄예방에 크게 기여할 수 있는 등 산업상 대단히 유용한 효과를 제공한다.Twisted fluorescent color yarn of the present invention is applied to a variety of security documents such as banknotes, securities, passports, national ID card, so that you can easily check the authenticity of the present invention provides a very useful effect in the industry, such as greatly contribute to the prevention of forgery and crime prevention.
