Description
본 발명은 친환경 복합 원단을 이용하여 제조되는 친환경 유니폼에 관한 것이다.The present invention relates to an eco-friendly uniform manufactured using an eco-friendly composite fabric.
매년 수백만 톤에서 수 천만 톤의 폐플라스틱이 바다로 유입되고 있으며 바다 1 ㎢ 당 100만개가 넘는 플라스틱 조각이 있다고 하며 플라스틱 조각은 아주 다양한 바다동물의 몸속에서 발견되고 있으며 바다 생물과 생태계, 사람의 건강 등에 끼치는 영향뿐만 아니라 오염으로 인하여 사회경제적 악영향이 우려되고 있다.Every year, millions to tens of millions of tons of waste plastic flows into the sea, and there are more than 1 million pieces of plastic per 1 km2 of the sea. Plastic pieces are found in the bodies of a wide variety of sea animals, and have a negative impact on sea life, the ecosystem, and human health. In addition to the impact on people's backs, there are concerns about negative socioeconomic impacts due to pollution.
우리나라는 쓰레기를 처리하는 데 소각과 매립 방식을 병행하고 있는데 주민들의 반대로 더 이상의 소각시설을 짓는 것은 불가능하며 세계 최대 규모인 수도권 매립지 또한 2025년 사용이 중단될 운명에 처해 있다. 또한, 세계 재활용 쓰레기의 절반 정도를 수입해 처리하던 중국이 세계무역기구(WTO)에 “환경 보호와 보건위생 개선을 위해 플라스틱 쓰레기와 전자제품 폐기물의 수입 제한 조처를 하겠다.”고 선언하면서 우리나라뿐만 아니라 세계 각국에서 ‘쓰레기 대란’이 일어나고 있다.Korea uses a combination of incineration and landfill methods to dispose of waste, but it is impossible to build any more incineration facilities due to opposition from residents, and the world's largest landfill in the metropolitan area is also destined to be discontinued in 2025. In addition, China, which imported and disposed of about half of the world's recyclable waste, declared to the World Trade Organization (WTO), "We will take measures to restrict the import of plastic waste and electronic waste to protect the environment and improve health and hygiene," thereby affecting not only Korea. In fact, a ‘garbage crisis’ is occurring all over the world.
이와 같은 문제에도 불구하고 최근까지도 플라스틱 제품의 재생 비율은 20~40%로 타제품 대비 상대적으로 낮은 수준이며 특히, 우리나라는 플라스틱의 높은 회수율에도 불구하고 고순도 재활용 플라스틱 제조기술 부족 및 고부가가치 제품화 기술 부족으로 재활용률 향상에 어려움을 겪고 있다.Despite these problems, the recycling rate of plastic products was 20-40% until recently, which is relatively low compared to other products. In particular, despite the high recovery rate of plastics in Korea, due to the lack of high-purity recycled plastic manufacturing technology and lack of high-value-added product technology, We are having difficulty improving the recycling rate.
폐플라스틱을 통해 생산되는 리사이클 플라스틱은 성분 및 Grade에 따라 다양한 분야에 적용이 가능하나 현재까지는 낮은 기술력을 요하는 플라스틱 사출품, 건축보강재, 포장용 밴드 등에 적용되고 있으며 보다 높은 수준의 기술을 요하는 섬유화 및 제품적용은 미비한 상태이다. Recycled plastics produced from waste plastics can be applied to various fields depending on their composition and grade, but are currently being applied to plastic injection products, building reinforcement materials, and packaging bands, which require low technology, and are made into fibers that require a higher level of technology. And product application is insufficient.
국내의 경우 대기업 및 중견기업(효성, 휴비스 등)을 중심으로 고순도 PET flake를 이용한 의류용 용도의 Recycle PET 섬유가 생산되고 있고 중소기업을 중심으로 토목용 및 자동차용 부직포 용도가 생산되고 있다.In Korea, recycled PET fibers for clothing are produced using high-purity PET flakes mainly by large and medium-sized companies (Hyosung, Huvis, etc.), and non-woven fabrics for civil engineering and automobiles are produced mainly by small and medium-sized companies.
이와 관련하여, 한국등록특허공보 제10-1015383호는 보틀 폐기물에 포함되어 있는 이물질을 제거하여 폴리에스테르 그래뉼의 순도를 확보하고, 용융 및 압출성형 함으로써 양호한 품질의 리사이클 폴리에스테르 섬유를 생산하는데 사용하는 폴리에스테르 재생칩의 제조방법에 대해 설명하고 있다.In this regard, Korean Patent Publication No. 10-1015383 is used to remove foreign substances contained in bottle waste, secure the purity of polyester granules, and produce good quality recycled polyester fiber by melting and extrusion molding. The manufacturing method of polyester recycled chips is explained.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 재생 폴리에스터를 적용하여 환경을 보호하는 장점이 있으며 부드럽게 내구성이 우수한 원단과 이를 적용한 친환경 유니폼을 제공하는 것이다.The present invention was created to solve the above problems, and the purpose of the present invention is to provide a soft, durable fabric that has the advantage of protecting the environment by applying recycled polyester, and an eco-friendly uniform using the same.
본 발명의 과제는 이상에서 언급한 과제들로 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The object of the present invention is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.
