<도면의 주요 부분에 대한 부호의 설명><Explanation of symbols for the main parts of the drawings>

110 : 내부 섬유층 120 : 외부 섬유층110: inner fiber layer 120: outer fiber layer

본 고안은 부직포 지오텍스타일에 관한 것으로서, 특히 쓰레기 매립장 건설시 침출수의 유출을 막기 위해 사용되는 고투과계수를 가진 부직포 지오텍스타일에 관한 것이다.The present invention relates to a nonwoven geotextile, and more particularly to a nonwoven geotextile having a high permeability coefficient used to prevent the outflow of leachate during the construction of landfills.

통상적으로, 쓰레기 매립장 건설시 매립장의 바닥에는 다짐점토층이나 다짐점토광물혼합토층을 설치하고, 그 위에 차수막을 설치한 후 모래 등으로 구성된 침 출수 집배수층을 설치한다. 또한, 상기 차수막과 침출수 집배수층 사이에는 높은 하중하에서도 차수막을 보호할 수 있도록 부직포 지오텍스타일, 지오네트, 지오컴포지트와 같은 보호재를 설치한다. In general, during the construction of a landfill site, a compacted clay layer or a compacted clay mineral mixed soil layer is installed at the bottom of the landfill site, and a leachate collection and drainage layer composed of sand or the like is installed after installing a water barrier. In addition, a protective material such as a nonwoven geotextile, a geonet, and a geo-composite is installed between the water repellent layer and the leachate drainage layer to protect the water repellent layer even under high load.

한편, 상기 지오컴포지트나 지오네트는 꿰뚫림 저항성이 약하기 때문에 보호재로서 부적합하므로 꿰뚫림 저항성 등 보호 특성이 우수한 부직포 지오텍스타일이 널리 사용되고 있다.On the other hand, since the geocomposite and the geonet is not suitable as a protective material because of its poor puncture resistance, nonwoven geotextiles having excellent protective properties such as puncture resistance are widely used.

상기와 같은 문제점을 해결하기 위하여 본 고안의 목적은 우수한 인장성 및 꿰뚫림 저항성을 가지면서도 높은 하중압력 하에서도 고투과계수를 가진 부직포 지오텍스타일을 제공하는데 있다. In order to solve the above problems, an object of the present invention is to provide a nonwoven geotextile having a high permeability even under high load pressure while having excellent tensile and puncture resistance.

또한, 본 고안의 다른 목적은 쓰레기 매립장의 침출수 유출을 안정적으로 차단할 수 있도록 고투과계수를 가진 부직포 지오텍스타일을 제공하는데 있다. In addition, another object of the present invention is to provide a non-woven geotextile having a high permeability coefficient to reliably block the leachate outflow of the landfill.

상기와 같은 목적을 달성하기 위하여 본 고안은 단위 면적당 중량이 1,000 ~ 2,000g/㎡이고 데니어가 30 ~ 1,000인 섬유를 수평 적층 혹은 프리펀칭한 부직포로 이루어진 내부 섬유층과; 단위면적당 중량이 300 ~ 1,000g/㎡이고 데니어가 3 ~ 15인 섬유를 프리펀칭한 부직포로 이루어지며, 상기 내부 섬유층의 양면에 니들 펀칭에 의해 결합된 한 쌍의 외부 섬유층을 포함함을 특징으로 하는 고투과계수를 가진 부직포 지오텍스타일을 제공한다.In order to achieve the above object, the present invention is an inner fiber layer made of a nonwoven fabric horizontally laminated or prepunched fibers of 1,000 to 2,000 g / ㎡ and denier 30 to 1,000 per unit area; It consists of a non-woven fabric prepunched a fiber of 300 ~ 1,000g / ㎡ and a denier 3 to 15 per unit area, characterized in that it comprises a pair of outer fiber layer bonded by needle punching on both sides of the inner fiber layer. It provides nonwoven geotextiles with high transmission coefficient.

이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 본 고안을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 고안의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

도 1은 본 고안의 바람직한 실시예에 따른 고투과계수를 가진 부직포 지오텍스타일을 나타낸 단면도이다. 도 1에 도시된 바와 같이 본 고안의 바람직한 실시예에 따른 고투과계수를 가진 부직포 지오텍스타일(100)은 내부 섬유층(110)과 한 쌍의 외부 섬유층(120) 등 총 삼단층으로 이루어진다. 1 is a cross-sectional view showing a nonwoven geotextile having a high permeability coefficient according to a preferred embodiment of the present invention. As shown in FIG. 1, the nonwoven geotextile 100 having a high permeability coefficient according to a preferred embodiment of the present invention consists of a total of three layers such as an inner fiber layer 110 and a pair of outer fiber layers 120.

(1) 내부 섬유층(1) inner fibrous layer

상기 내부 섬유층(110)은 본 고안인 부직포 지오텍스타일(100)의 중심 섬유층이다. The inner fiber layer 110 is a central fiber layer of the nonwoven geotextile 100 of the present invention.

상기 내부 섬유층(110)은 단위 면적당 중량이 1,000 ~ 2,000g/㎡이고 데니어가 30 ~ 1,000인 섬유를 수평 적층 혹은 프리펀칭한 부직포로 이루어진다. The inner fiber layer 110 is made of a nonwoven fabric in which the weight per unit area is 1,000 to 2,000 g / m 2 and the denier is 30 to 1,000 fibers laminated or prepunched.

상기 내부 섬유층(110)의 데니어가 30 미만인 경우에는 원하는 투과계수를 얻을 수 없고, 1,000 이상인 경우에는 적층을 하거나 프리펀칭하는데 어려움이 있다. If the denier of the inner fiber layer 110 is less than 30, the desired transmission coefficient cannot be obtained, and if it is 1,000 or more, it is difficult to laminate or prepunch.

상기 내부 섬유층(110)은 천연 섬유, 합성 섬유 등 재질에 한정은 없으나, 바람직하게는 침출수에 대한 화학적 변화가 적은 폴리프로필렌 섬유로 구성한다. The inner fibrous layer 110 is not limited to materials such as natural fibers and synthetic fibers, but is preferably made of polypropylene fibers with less chemical change to leachate.

(2) 외부 섬유층(2) outer fiber layer

상기 외부 섬유층(120)은 내부 섬유층(110)의 양면에 니들 펀칭에 결합된 섬유층이다. The outer fibrous layer 120 is a fibrous layer coupled to needle punching on both sides of the inner fibrous layer 110.

상기 외부 섬유층(120)은 단위면적당 중량이 300 ~ 1,000g/㎡이고 데니어가 3 ~ 15인 섬유를 프리펀칭한 부직포로 이루어진다. The outer fiber layer 120 is made of a nonwoven fabric prepunched a fiber of 300 ~ 1,000g / ㎡ and denier 3 to 15 weight per unit area.

상기 외부 섬유층(120)을 내부 섬유층(110)과 니들 펀칭으로 결합하는 이유는 섬유간 구속력을 높여 인장성과 꿰뚫림 저항성을 높이기 위함이다. The reason why the outer fiber layer 120 is coupled to the inner fiber layer 110 by needle punching is to increase the binding force between the fibers by increasing the binding force between the fibers.

상기 외부 섬유층(120)의 데니어가 3 미만이거나 15를 초과하는 경우에는 인장성 및 꿰뚫림 저항성이 저하된다. If the denier of the outer fiber layer 120 is less than 3 or more than 15, the tensile and puncture resistance is lowered.

상기 외부 섬유층(120)은 폴리프로필렌, 폴리에스테르가 바람직하다. The outer fiber layer 120 is preferably polypropylene, polyester.

<실시예><Example>

내부 섬유층을 구성하기 위해 5 데니어인 폴리프로필렌 섬유로 된 웹을 수평 적층하고 프린 펀칭하였다. 이때, 내부 섬유층의 웹 중량은 1,500g/㎡을 유지하였다. 또한, 외부 섬유층을 구성하기 위해 10 데니어인 폴리프로필렌 섬유로 된 웹을 프리 펀칭하였다. 이때, 외부 섬유층의 웹 중량은 500g/㎡을 유지하였다. 이어, 상기 내부 섬유층 양면에 각각 외부 섬유층을 놓고 니들 펀칭으로 결합하였다. To make up the inner fibrous layer, webs of 5 denier polypropylene fibers were horizontally laminated and printed punched. At this time, the web weight of the inner fiber layer was maintained at 1,500 g / ㎡. In addition, a web of 10 denier polypropylene fibers was prepunched to form an outer fibrous layer. At this time, the web weight of the outer fiber layer was maintained at 500g / ㎡. Subsequently, the outer fiber layer was placed on both sides of the inner fiber layer and bonded by needle punching.

완성된 부직포 지오텍스타일의 투과계수는 10kPa시 2.3 × 10-4 (m2/sec), 100kPa시 1.1 × 10-4 (m2/sec), 200kPa시 8.0 × 10-4 (m2/sec)로 각각 측정되었다. The transmission coefficient of the finished nonwoven geotextile is 2.3 × 10 -4 (m 2 / sec) at 10 kPa, 1.1 × 10 -4 (m 2 / sec) at 100 kPa, 8.0 × 10 -4 (m 2 / sec) at 200 kPa Were measured respectively.

상술한 바와 같이 본 고안의 실시예에 따른 고투과계수를 가진 부직포 지오텍스타일은 우수한 인장성 및 꿰뚫림 저항성을 가지면서도 높은 하중압력 하에서도 높은 투과계수를 가져, 쓰레기 매립장 건설시 차수막을 안전하게 보호하고, 사면의 안정성을 높이는 효과가 있다.As described above, the non-woven geotextile having a high permeability coefficient according to the embodiment of the present invention has a high permeability even under high load pressure while having excellent tensile and puncture resistance, thereby safely protecting the screen when constructing a landfill, It is effective to increase the stability of the slope.
