본 발명은 대나무 섬유를 주재료로 하는 친환경 현수막에 관한 것으로서, 특히 용도 폐기된 현수막을 매립하거나 소각할 경우에 환경을 오염시킬 우려가 없고, 나아가 게양 도중에는 공기 중에 포함되어 있는 각종 환경 오염 물질을 흡착하여 공기를 정화하는 능력이 있는 친환경 현수막에 관한 것이다.
The present invention relates to an environmentally friendly banner based on bamboo fibers, and particularly, when the discarded banner is discarded or incinerated, there is no risk of polluting the environment, and furthermore, by adsorbing various environmental pollutants contained in the air during the hoisting process. An environmentally friendly banner with the ability to purify the air.
잘 알려진 바와 같이, 현수막(懸垂幕)은 각종 선전문이나 행사 안내문 따위를 적어서 벽에 걸어두거나 공중에 매달아 두는 막으로서, 각종 스포츠 경기나 지방 자치단체 행사, 정치 현장 등에서 널리 이용되고 있다.As is well known, banners are hanging on a wall or hanging in the air with various prefaces or event announcements, and are widely used in various sports events, municipal events, and political scenes.
이러한 현수막은 실내에 게양하기도 하지만, 예컨대 도로변과 같이 사람들의 통행이 빈번한 곳에 게양해 두기도 하며, 한번 게양하면 수일 내지 수주일간 그대로 매달아 두었다가 회수하여 폐기한다. Such banners may be hoisted indoors, but may be hoisted in places where people pass frequently, such as roadsides, and once hoisted, they are suspended for days or weeks and then collected and discarded.
따라서 현수막을 제작하는데 사용되는 원단은 통상적으로 가격이 저렴하고, 비바람에 강하며, 나염 인쇄가 용이한 재질의 원단을 사용하며, 그 크기는 보통 폭이 1.5 ~ 2.0 미터, 길이가 10 ~ 15 미터 정도에 이른다.Therefore, the fabrics used to make banners are usually made of inexpensive, weatherproof, and easy-to-print materials, which are usually 1.5 to 2.0 meters wide and 10 to 15 meters long. It reaches a degree.
종래 가장 널리 사용되고 있는 나염 현수막 원단은 폴리에스테르 합성섬유로 제직된 것으로서, 100% 폴리에스테로 섬유로만 이루어진 T/P와, 폴리에스테르 65%와 면 35%로 이루어진 T/C, 폴리에스테르 35%와 레이온 35%로 이루어진 T/R 원단이 주로 사용되고 있다.The most widely used printing screens are printed with polyester synthetic fibers, T / P made of 100% polyester fiber, T / C made of 65% polyester and 35% cotton, and 35% polyester. T / R fabric made of 35% rayon is mainly used.
그런데 상기와 같은 종래의 폴리에스테르 현수막은 이를 다 사용한 후 폐기하는 절차가 새로운 골칫거리로 대두되고 있다. 특히 선거철이나 축제 등 각종 행사 기간에는 하루에 무려 수십톤에 달하는 엄청난 양의 폐 현수막이 수거되며 이들은 대부분 소각 또는 매립 처분된다.However, the conventional polyester placard as described above is emerging as a new headache as a procedure for disposal after it is used up. Especially during elections and festivals, huge amounts of dozens of tons of waste banners are collected each day, most of which are incinerated or landfilled.
그런데 종래의 폴리에스테르 현수막을 소각할 경우, 많은 공해물질들이 발생하는 문제가 있고, 매립할 경우에는 적어도 수십년 동안 썩지 않기 때문에 토양을 오염시킬 뿐 아니라, 적당한 매립 장소를 찾는 것도 쉽지 않은 것이 현실이다.
However, incineration of conventional polyester banners has a problem that many pollutants are generated, and when it is buried, it does not rot for at least several decades, so it is not easy to pollute the soil and find a suitable landfill site. .
이에 본 발명이 해결하고자 하는 과제는 용도 폐기된 현수막을 소각 또는 매립 처분하는 과정에서 환경오염의 우려가 없고, 나아가 게양 도중에는 공기 중에 포함되어 있는 각종 유해물질들을 흡착, 제거하여 공기를 정화하는 능력이 있는 새로운 개념의 친환경 현수막을 제공하는 것이다.
Therefore, the problem to be solved by the present invention is that there is no fear of environmental pollution in the process of incineration or landfill disposal of discarded banners, and furthermore, the ability to purify the air by adsorbing and removing various harmful substances contained in the air during hoisting. To provide a new concept of eco-friendly banners.

Eco-friendly banner according to the invention is characterized in that consisting of 60% by weight bamboo fiber, 30% by weight PLA fiber, and 10% by weight cotton fiber.
본 발명에 따른 친환경 현수막은 생분해성으로서 사용 후 매립하면 1 년 이내에 토양 미생물에 의해 완전분해 되고, 소각시에는 완전 연소되어 소각 잔사를 남기지 않으며 유독성 물질을 전혀 배출하지 않기 때문에 환경 오염의 우려가 전혀 없다.Eco-friendly banners according to the present invention are biodegradable and completely decomposed by soil microorganisms within one year after being used, and are completely burned during incineration, leaving no residue of incineration, and releasing no toxic substances at all, so there is no concern about environmental pollution. none.
또한, 본 발명에 따른 친환경 현수막은 공기 중에 포함되어 있는 환경오염 물질, 특히 포름알데히드, 톨루엔, 암모니아를 흡착, 제거하는 능력이 있어서, 실내 또는 실외에 게양되어 있는 동안에 공기를 정화하는 능력이 있다.
In addition, the environmentally friendly banner according to the present invention has the ability to adsorb and remove environmental pollutants, especially formaldehyde, toluene and ammonia contained in the air, and thus has the ability to purify the air while being hoisted indoors or outdoors.
본 발명에 따른 친환경 현수막은 대나무 섬유를 주재료로 포함하는 것이다. 상기 대나무 섬유는 우리나라에 널리 자생하는 대나무에서 셀룰로오스를 추출하여 비스코스 공법으로 섬유화 하는 방법으로 만든 순수 식물성 섬유로서, 국내 특허 등록 제0754315호(등록일자; 2007.08.27) 및 제0547491호(등록일자; 2006.01.23) 등에 그 제조방법이 소개되어 있다. Eco-friendly banner according to the present invention is to include bamboo fiber as a main material. The bamboo fiber is a pure vegetable fiber made by a method of fiberizing by extracting cellulose from the bamboo native to Korea and viscose method, domestic patent registration 0754315 (registration date; 2007.08.27) and 0547491 (registration date; 2006.01.23) and the manufacturing method is introduced.
이러한 대나무 섬유는 생분해성 천연섬유로서, 주성분이 되는 셀룰로오스의 말단에 수산화기(-OH)를 포함하고 있어서 물에 대한 친화도가 매우 높다. 따라서, 종래의 합성섬유 소재와는 달리, 비이온 계면활성제 등의 화학물질을 별도로 첨가하지 않아도 우수한 친수성을 가지며, 건조한 환경조건에서도 정전기 발생량이 적은 매우 친환경적인 소재로서, 종래에는 주로 속옷이나, 기저귀, 생리용품 등의 소재로 제한적으로 사용해 왔다.Such bamboo fiber is a biodegradable natural fiber, and contains a hydroxyl group (-OH) at the end of cellulose which is a main component, and has a high affinity for water. Therefore, unlike conventional synthetic fiber materials, it has excellent hydrophilicity without adding chemicals such as non-ionic surfactants, and is a very environmentally friendly material having a small amount of static electricity even in dry environmental conditions. It has been used in a limited amount of materials, such as sanitary products.
본 발명에서는 상기와 같은 대나무 섬유를 현수막용 원단의 주재료로 사용하는 것이다. 본 발명에 따른 친환경 현수막은 굵기가 50 ~ 1,000 데니아인 대나무 섬유 60 ~ 100 중량%를 포함하는데, 만일 상기 대나무 섬유의 굵기가 50 데니아 미만이면 원단의 강도가 너무 약해서 쉽게 찢어지거나 파손될 우려가 있고, 반대로 1,000 데니아 이상이면 원단의 두께가 너무 두꺼워져서 바람직하지 않다.In the present invention, the bamboo fiber as described above is to be used as the main material of the fabric for banners. Eco-friendly placard according to the present invention includes 60 to 100% by weight of bamboo fiber having a thickness of 50 to 1,000 denier, if the thickness of the bamboo fiber is less than 50 denier, the strength of the fabric is too weak to be easily torn or broken, On the contrary, if the thickness is 1,000 denier or more, the thickness of the fabric is too thick, which is not preferable.
또한 본 발명에 따른 친환경 현수막은 대나무 섬유 60 ~ 80중량%와, 면 섬유, PLA 섬유, 레이온 섬유, PET 섬유 중에서 선택된 어느 하나 이상의 섬유 20 ~ 40 중량%로 이루어진 것을 특징으로 한다. In addition, the eco-friendly banner according to the invention is characterized in that consisting of 20 to 40% by weight of any one or more fibers selected from 60 to 80% by weight of bamboo fibers, cotton fibers, PLA fibers, rayon fibers, PET fibers.
상기 면 섬유는 목화에서 뽑은 섬유로서, 가늘고 유연하며 습기를 잘 흡수하는 특성이 있어서 상기 친환경 현수막의 잉크 발색도를 향상시켜 주는 역할을 한다.The cotton fiber is a fiber drawn from cotton, and has a thin, flexible, moisture-absorbing property, thereby improving the ink color development of the eco-friendly banner.
다음으로 PLA 섬유는 폴리젖산(PLA; Poly Lactic Acid)을 방사 및 성형하여서 된 섬유이다. 상기 폴리젖산은 옥수수나 감자 등과 같은 곡물원료로부터 제조되는 생분해성 수지(Biodegradable resin)의 일종으로서 박테리아나 곰팡이 등 자연 상태에 존재하는 미생물에 의해 수년 내에 물과 이산화탄소, 메탄가스 등으로 완전히 분해되는 고분자 물질이다. 상기 PLA 섬유는 본 발명에 따른 친환경 현수막의 성형성과 염색성을 향상시켜 주고, 매립시에는 분해를 촉진하는 역할을 한다.Next, the PLA fiber is a fiber obtained by spinning and forming poly lactic acid (PLA). The polylactic acid is a kind of biodegradable resin prepared from grain raw materials such as corn or potato, and is a polymer that is completely decomposed into water, carbon dioxide, and methane gas in a few years by microorganisms in nature such as bacteria or fungi. It is a substance. The PLA fiber improves the moldability and dyeing properties of the environmentally friendly banner according to the present invention, and serves to promote decomposition when buried.
또한 레이온(Rayon) 섬유는 목재 펄프나 무명 린터(Cotton linter)등과 같이 길이가 너무 짧아서 그대로는 섬유로 사용 할 수 없는 것들을 적당한 용제에 녹인 다음 습식 방사하여 섬유 모양으로 재생시킨 인조 섬유의 일종으로서, 본 발명에서는 현수막 원단의 인장강도를 보강해 주는 역할을 한다.In addition, rayon fiber is a kind of artificial fiber which is made by dissolving things that are too short, such as wood pulp or cotton linter, that cannot be used as a fiber in a suitable solvent, and then wet spinning them into fiber shapes. In the present invention serves to reinforce the tensile strength of the banner fabric.
마지막으로 PET 섬유는 폴리에틸렌 테레프탈레이트(Polyethylene terephthalate) 폴리머를 원료로 하는 합성 섬유로서, 가격이 비교적 저렴하고 기계적 물성이 우수하여 본 발명에서는 현수막 원단의 인장강도를 보강해 주는 역할을 한다.
Finally, PET fiber is a synthetic fiber made of polyethylene terephthalate (Polyethylene terephthalate) polymer as a raw material, the price is relatively inexpensive and excellent mechanical properties in the present invention serves to reinforce the tensile strength of the banner fabric.
본 발명의 일 실시예에 따른 친환경 현수막은 대나무 섬유 70중량%와, 면 섬유 20 중량%, 그리고 레이온 섬유 10 중량%로 이루어진다.Eco-friendly banner according to an embodiment of the present invention consists of 70% by weight bamboo fiber, 20% by weight cotton fiber, 10% by weight rayon fiber.
본 발명의 다른 일 실시예에 따른 친환경 현수막은 대나무 섬유 60중량%와, PLA 섬유 30 중량%, 그리고 면 섬유 10 중량%로 이루어진다. Eco-friendly banner according to another embodiment of the present invention consists of 60% by weight bamboo fiber, 30% by weight PLA fiber, and 10% by weight cotton fiber.
이와 같이, 본 발명에 따른 친환경 현수막은 식물성 천연섬유인 대나무 섬유를 주재료로 하기 때문에 매립시에는 토양 미생물에 의해서 1년 이내에 탄산가스와 물로 완전 분해되고, 소각시에는 연소 에너지가 낮고 소각 후 잔사를 하나도 남기지 않으며, 유독성 물질이 전혀 발생하지 않는 특징이 있다. As described above, the eco-friendly banner according to the present invention is made of bamboo fiber, which is a vegetable natural fiber, as a main material, and is completely decomposed into carbon dioxide and water within one year by soil microorganisms at the time of reclamation. It leaves no one, and it is characterized by no toxic substances.
한편, 본 발명에 따른 친환경 현수막은 상기와 같은 특징에 더하여 놀랍게도 공기 중에 포함되어 있는 각종 휘발성 공해물질, 예컨대 포름알데히드, 톨루엔, 암모니아 등을 흡착, 제거하여 공기를 정화하는 능력이 있다는 사실이 본 발명자에 의해서 처음으로 확인되었다. On the other hand, the present invention is an environmentally friendly banner according to the present invention surprisingly has the ability to purify the air by absorbing and removing various volatile pollutants, such as formaldehyde, toluene, ammonia, etc. contained in the air surprisingly First identified by
상기 현수막이 이러한 특성을 갖는 것은 대나무 섬유의 독특한 구조적 특성에 기인하는 것으로 짐작된다. 즉, 대나무 섬유를 현미경으로 확대해 보면, 그 표면에는 마치 숯과 같이 가늘고 긴 공동(空洞)들이 무수히 형성되어 있는데, 이러한 동공들이 상기 휘발성 공해물질들을 흡착하는 것으로 짐작된다.It is presumed that the banner has this property due to the unique structural properties of the bamboo fibers. In other words, when the bamboo fiber is magnified under a microscope, numerous thin elongated cavities, such as charcoal, are formed on the surface thereof, and these pores are assumed to adsorb the volatile pollutants.
따라서 본 발명에 따른 친환경 현수막은 실내는 물론 실외에 게양해 둔 동안에 공기 중에 포함되어 있는 각종 휘발성 공해물질을 흡착, 제거하여 공기를 정화하는 성능이 있다.
Therefore, the eco-friendly banner according to the present invention has the ability to purify the air by adsorbing and removing various volatile pollutants contained in the air while being hoisted indoors as well as outdoors.
이하, 본 발명에 따른 친환경 현수막의 공기 정화 능력을 측정하고, 그 결과를 설명한다.
Hereinafter, the air purification capacity of the environmentally friendly banner according to the present invention is measured, and the results are described.

다. 시험방법 ; 실내온도가 20 ~ 30℃ 이고, 상대습도가 25 ~65% 인 조건하에서 용량이 10 리터인 시험용기, 즉 테틀라백 안에 상기 시료 A, B를 각각 투입하고 밀봉한 다음, 상기 테틀라백 안에다 각각 시험대상물질, 즉 포름알데히드 20 ppm, 톨루엔 50 ppm, 암모니아 100 ppm, 일산화탄소 50 ppm을 주입하였다. All. Test method ; Into a test container with a capacity of 10 liters under a condition of a room temperature of 20 to 30 ° C. and a relative humidity of 25 to 65%, that is, the samples A and B, respectively, were sealed and then put into each of the tela bags. Test substance was injected, namely 20 ppm of formaldehyde, 50 ppm of toluene, 100 ppm of ammonia, and 50 ppm of carbon monoxide.
가스검지기(GV-100S, GASTEC Co., Japan)를 이용하여 초기, 0.5시간, 1시간, 2 시간, 4 시간, 6시간 경과된 시점에서 각각 상기 시험대상물질들의 농도변화를 측정하였다. 그리고, 공시험으로서 테틀라백에 상기 시료를 투입하지 않은 상태에서 동일한 방법으로 각 시험대상물질의 농도를 측정하였다.
Gas concentrations (GV-100S, GASTEC Co., Japan) were used to measure the concentration change of the test substances at the time points of 0.5 hours, 1 hour, 2 hours, 4 hours, and 6 hours, respectively. As a blank test, the concentration of each test subject was measured in the same manner without the sample being added to the Tetra bag.
4) 시험결과4) Test result
상기 표 1의 결과로부터 알 수 있는 바와 같이, 본 발명에 따른 친환경 현수막은 포름알데히드의 농도를 45 ~ 50%, 톨루엔의 농도를 42 ~ 48%, 암모니아의 농도를 68 ~ 69% 각각 낮추어 주는 효과가 있는 것으로 나타났으며, 특이하게도 일산화탄소의 농도를 낮추어 주는 효과는 전혀 없었다.As can be seen from the results of Table 1, the eco-friendly banner according to the present invention has an effect of reducing the concentration of formaldehyde 45 ~ 50%, the concentration of toluene 42 ~ 48%, the concentration of ammonia 68 ~ 69%, respectively It was found that, in particular, there was no effect to lower the concentration of carbon monoxide.
그리고, 상기 3가지 시험대상물질에 대하여 초기 30분 이내에 현저한 흡착효과를 보였으며, 2시간 경과 이후에는 아무런 흡착효과가 나타나지 않았다. 그리고, 시료 A에 비해 시료 B의 효과가 약간 우수한 것은 각 시료 속에 포함된 대나무 섬유의 구성비율의 차이에 기인한 것으로 추측 된다.In addition, the three test subjects showed remarkable adsorption effects within the initial 30 minutes, and no adsorption effect appeared after 2 hours. In addition, the effect of Sample B is slightly superior to Sample A is presumed to be due to the difference in the composition ratio of the bamboo fibers contained in each sample.
한편 공시험에서는 모든 시험대상물질에서 아무런 농도변화가 일어나지 않았다. On the other hand, in the blank test, no concentration change occurred in all the test substances.
