Description
본 발명은 다공성시트에 관한 것으로, 보다 상세하게는 코코넛섬유를 이용한 다공성시트 및 그 제조방법에 관한 것이다. The present invention relates to a porous sheet, and more particularly to a porous sheet using a coconut fiber and a method of manufacturing the same.
널리 주지된 바와 같이, 코코넛섬유는 코코넛에서 추출한 섬유질이다. As is well known, coconut fiber is a fiber extracted from coconut.
코코넛섬유는 화학섬유와 달리 특이체질에 따른 알레르기 또는 정전기 등을 유발하지 않고, 불에 태워도 유독가스를 발생하지 않는다. 또한, 외부의 습도에 따라 흡습 및 탈습작용을 하여 일정한 습도를 유지할 수 있는 특성 때문에 쿠션이나 매트리스의 충전재 등과 같은 침구류에 이용된다. Coconut fiber, unlike chemical fiber, does not cause allergies or static electricity due to specific constitutions, and does not generate toxic gas even when burned. In addition, it is used for bedding, such as cushions or mattress fillers because of the ability to maintain a constant humidity by absorbing and dehumidifying according to the external humidity.
또한, 코코넛섬유는 짧고 조강(粗剛)하며 강도도 그리 크지는 않지만 비교적 탄력성(彈力性)이 있고 가벼우며 물, 특히 바닷물에서 잘 썩지 않는 특성이 있다. 이 때문에 로프·어망, 배의 충전재(充塡材), 빗자루, 그외 건축 또는 가구의 원자재 등으로 많이 이용된다. In addition, coconut fiber is short, rough, and not very strong, but relatively elastic (彈力 性) and light and has a characteristic that does not rot well in water, especially seawater. For this reason, it is widely used for ropes, fishing nets, ship fillings, brooms, and other raw materials for construction or furniture.
최근에는 상기의 코코넛섬유와 같이 환경친화적인 천연섬유를 이용한 다공성시트가 연구 개발되고 있다. 이러한 다공성시트는 각종 침구류, 가구 또는 건축용 원자재 등으로 널리 이용되고 있다. Recently, porous sheets using environmentally friendly natural fibers such as coconut fiber have been researched and developed. Such porous sheets are widely used in various beddings, furniture or building materials.
하지만, 종래의 코코넛섬유를 이용한 다공성시트는 그 제조공정이 매우 번거로워 제조비용이 높았고, 이에 따라 고가의 침구류, 건축용 원자재 등에만 이용되는 등 그 적용범위가 극히 제한적인 단점이 있었다. However, the conventional porous sheet using a coconut fiber has a high manufacturing cost because the manufacturing process is very cumbersome, there is a disadvantage that the scope of application is extremely limited, such as used only in expensive bedding, building materials and the like.
또한, 침구류, 가구 또는 건축용 원자재로 이용되는 다공성시트는 그 통풍성, 흡음성, 방음성, 항균성 뿐만 아니라 중량 대비 강도가 높아야 하지만, 종래의 다공성시트는 이와 같은 특성들을 충족시키지 못하는 단점이 있었다. In addition, the porous sheet used as a bedding material, furniture or building raw materials should have a high strength to weight as well as its breathability, sound absorption, soundproofing, antibacterial properties, the conventional porous sheet has a disadvantage that does not meet these characteristics.
