Description
인류의 문명과 함께 필수 불가결한 의복의 원료물질인 섬유는 최초 자연에서 얻어지는 천연섬유만이 사용되었으나 20세기 이후 화학공업의 발달과 더불어 여러 가지 합성섬유가 개발되어 인류의 생활을 풍요롭게 하였으나 이들은 대부분 자연분해가되지 않는 성질을 가지고 있어 현재 인류는 폐섬유로 인한 심각한 환경오염의 문제에 직면해 있다.As a raw material of clothing, which is essential to human civilization, only the first natural fiber obtained from nature was used, but since the 20th century, with the development of chemical industry, various synthetic fibers have been developed to enrich human life. Due to its non-degradable nature, human beings are currently facing serious environmental pollution caused by waste fiber.
최근 폐섬유로 인한 환경오염문제가 지각되며 이를 재활용하려는 연구가 폭넓게 진행되고 있다. 미국특허 제603782호에서는 폐섬유를 기계적으로 분해하여 혼합 후 부직포를 형성시켜 사용하는 기술을 소개하고 있으며 미국특허 제3978179호에서는 열가소성수지를 폐섬유와 혼합하여 바인더로 사용하여 형태안정성이 개선된 부직포의 제조가 가능하다는 기술을 소개하고 있다. 하지만 이들은 모두 폐섬유를 이용하는 것 이외에 아무런 장점이 없으며 기능성 또한 전혀 기대할 수 없으며 아직 폐섬유를 이용하여 제조되는 내열성 고강도 재생 섬유합판에 관한 내용은 없다.Recently, environmental pollution problem caused by waste fiber is perceived, and research to recycle it has been widely conducted. U.S. Patent No. 607882 introduces the technique of mechanically decomposing waste fibers to form non-woven fabrics after mixing them, and U.S. Patent No. 3978179 uses non-woven fabrics with improved shape stability by mixing thermoplastic resins with waste fibers. It introduces the technology that can be manufactured. However, they all have no advantages other than using waste fibers, and they cannot be expected at all, and there is no information on heat-resistant high-strength recycled fiber plywood manufactured using waste fibers.
