본 발명의 가장 큰 특징은 천연섬유인 아바카(abaca; 마닐라 삼) 섬유와 대마(Cannabis sativa L) 섬유 및 핫멜트 접착제인 폴리아마이드 필름을 이용하여 마감재를 구성함으로써, 마감재로서 적합한 물성을 제공하고, 탈취, 항균의 기능성을 가지며, 인체에 유해한 성분을 배출하지 않고, 환경오염을 야기하지 않도록 하는 데 있다.The greatest feature of the present invention is that the finishing material is constructed using natural fibers abaca (manila hemp) fiber and hemp (Cannabis sativa L) fiber and a polyamide film that is a hot melt adhesive, thereby providing suitable physical properties as a finishing material, It has deodorizing and antibacterial functions, does not emit substances harmful to the human body, and does not cause environmental pollution.

상기한 본 발명의 삼을 이용한 바이오복합 마감재는, 도 1에서와 같이, 아바카 섬유와 폴리프로필렌 섬유를 포함하는 제1부직포(1); 상기 제1부직포(1)에 적층되며, 대마 섬유와 폴리프로필렌 섬유를 포함하는 제2부직포(2); 및 상기 제1부직포(1)와 상기 제2부직포(2) 사이에 개재되어 상기 제1부직포(1)와 상기 제2부직포(2)를 접착하는 핫멜트 접착제인 폴리아마이드 필름(3);을 포함하는 것을 특징으로 한다.The bio-composite finishing material using hemp of the present invention described above is, as shown in FIG. 1, a first nonwoven fabric (1) comprising abaca fibers and polypropylene fibers; a second nonwoven fabric (2) laminated on the first nonwoven fabric (1) and comprising hemp fibers and polypropylene fibers; and a polyamide film (3) which is a hot melt adhesive interposed between the first nonwoven fabric (1) and the second nonwoven fabric (2) to bond the first nonwoven fabric (1) and the second nonwoven fabric (2); characterized in that

즉, 본 발명은 천연섬유로 구성된 제1, 2부직포(1)(2)의 합지를 통해 기계적 물성을 개선하고, 각종 마감재로서 사용이 적합하도록 하며, 탈취, 항균성 등의 기능성을 갖도록 하는 것이다.That is, the present invention is to improve mechanical properties through lamination of the first and second nonwoven fabrics (1) and (2) composed of natural fibers, make them suitable for use as various finishing materials, and have functionalities such as deodorization and antibacterial properties.

먼저, 상기 제1부직포(1)는 마닐라마 섬유인 아바카(abaca) 섬유와 폴리프로필렌 섬유를 포함하여 구성된다. First, the first nonwoven fabric 1 is configured to include abaca fibers, which are manila hemp fibers, and polypropylene fibers.

상기 아바카(abaca) 섬유는 마닐라 마의 입에서 채취하는 엽맥 섬유로, 강도가 강하며, 그 형태가 변형되지 않아 마감재의 인장강도 등과 같은 기계적 물성을 향상시키는 역할을 한다. 아울러, 흡습성이 우수하여 마감재로 사용시 실내 습도를 조절하는 역할을 한다. 상기 아바카 섬유는 공지의 공정으로 제조되는바, 이는 이 기술이 속하는 분야에서 충분히 공지되었으므로, 이에 대한 상세한 설명은 생략한다.The abaca fiber is a leaf vein fiber collected from the mouth of manila hemp, has strong strength, and does not deform its shape, thereby improving mechanical properties such as tensile strength of a finishing material. In addition, due to its excellent hygroscopicity, it plays a role in controlling indoor humidity when used as a finishing material. The abaca fiber is manufactured by a known process, which is well known in the field to which this technology belongs, and thus a detailed description thereof will be omitted.

상기 폴리프로필렌 섬유는 인체 유해물질을 배출하지 않는 안전한 소재로, 저신도, 고강도의 특성을 가진다. 본 발명에서 상기 폴리프로필렌 섬유를 상기 아바카 섬유와 혼합하여 사용하는 이유는, 부직포의 본딩을 원활하게 하여 섬유간 결합성을 높여주며, 기계적 물성 역시 개선하기 위함이다. The polypropylene fiber is a safe material that does not emit harmful substances to the human body, and has characteristics of low elongation and high strength. The reason why the polypropylene fiber is mixed with the abaca fiber in the present invention is to facilitate bonding of the nonwoven fabric to increase the bondability between the fibers, and also to improve mechanical properties.

상기 폴리프로필렌 섬유는 시판되는 섬유 중 어떠한 것이라도 이용할 수 있는바, 예시적으로 폴리프로필렌을 용융하고, 압출, 방사하여 미연신사를 제조하고, 이를 연신비 1.5~4.0로 연신한 후, 권축을 부여하고, 절단하여 제조할 수 있다. 또한, 필요에 따라 방사유제를 사용할 수도 있다.As the polypropylene fiber, any commercially available fiber can be used. For example, polypropylene is melted, extruded, and spun to prepare an undrawn yarn, stretched at a draw ratio of 1.5 to 4.0, and then crimped and , can be produced by cutting. In addition, if necessary, a spinning emulsion may be used.

상기 제1부직포(1)를 구성함에 있어서 상기 아바카 섬유와 폴리프로필렌 섬유의 사용량은, 상기 아바카 섬유 100중량부에 대하여 상기 폴리프로필렌 섬유 10~40중량부임이 바람직한바, 폴리프로필렌 섬유가 10중량부 미만이면 부직포의 본딩이 원활하지 못하고, 40중량부를 초과하면 친환경성이 저하되는 단점이 있기 때문이다.In constituting the first nonwoven fabric 1, the amount of the abaca fiber and the polypropylene fiber used is preferably 10 to 40 parts by weight of the polypropylene fiber based on 100 parts by weight of the abaca fiber, and the polypropylene fiber is 10 If it is less than 40 parts by weight, the bonding of the nonwoven fabric is not smooth, and if it exceeds 40 parts by weight, the environment-friendliness is deteriorated.

그리고 상기 제1부직포(1)의 두께는 0.5~8mm이고, 평량이 280~320g/㎡ 정도임이 바람직한바, 이는 전체적인 마감재의 물성을 고려한 것이다.And, the thickness of the first nonwoven fabric 1 is 0.5 to 8 mm, and it is preferable that the basis weight is about 280 to 320 g/m 2 , which is in consideration of the physical properties of the overall finishing material.

상기 제1부직포(1)에 적층되는 제2부직포(2)는 대마 섬유와 폴리프로필렌 섬유를 포함하여 구성된다.The second nonwoven fabric 2 laminated on the first nonwoven fabric 1 includes hemp fibers and polypropylene fibers.

상기 대마 섬유는 섬유질 자체에 항균, 항독, 방충성을 가지고 있으며, 암모니아, 초산, 이소발레르산 등의 악취의 발생을 방지하고, 억제하는 효과가 있다. 또한, 다른 천연섬유에 비하여 내구성이 뛰어나고, 강도가 우수하며, 형태 변형성 역시 적다는 장점이 있다. 따라서, 각종 마감재로 적용시 실내 환경을 쾌적하게 유지시켜 주는 역할을 한다.The hemp fiber has antibacterial, anti-toxic, and insect repellent properties in the fiber itself, and has an effect of preventing and inhibiting the generation of odors such as ammonia, acetic acid, and isovaleric acid. In addition, compared to other natural fibers, the durability is excellent, the strength is excellent, and the shape deformability is also small. Therefore, when applied as various finishing materials, it serves to maintain a pleasant indoor environment.

상기 폴리프로필렌 섬유는 상기 제1부직포에서 설명한 내용과 동일하다.The polypropylene fibers are the same as those described in the first nonwoven fabric.

상기 제1부직포(2)를 구성함에 있어서 상기 대마 섬유와 폴리프로필렌 섬유의 사용량은, 상기 대마 섬유 100중량부에 대하여 상기 폴리프로필렌 섬유 10~40중량부임이 바람직한바, 폴리프로필렌 섬유가 10중량부 미만이면 부직포의 본딩이 원활하지 못하고, 40중량부를 초과하면 친환경성이 저하되는 단점이 있기 때문이다.In constituting the first nonwoven fabric (2), the amount of hemp fibers and polypropylene fibers used is preferably 10 to 40 parts by weight of the polypropylene fibers based on 100 parts by weight of the hemp fibers, and the polypropylene fibers are 10 parts by weight. If it is less than, the bonding of the nonwoven fabric is not smooth, and if it exceeds 40 parts by weight, there is a disadvantage in that environmental friendliness is deteriorated.

그리고 상기 제2부직포(2)의 두께는 0.7~1mm이고, 평량이 250~270g/㎡ 정도임이 바람직한바, 이는 전체적인 마감재의 물성을 고려한 것이다.And, the thickness of the second nonwoven fabric 2 is 0.7 to 1 mm, and it is preferable that the basis weight is about 250 to 270 g/m 2 , which is in consideration of the physical properties of the overall finishing material.

본 발명에서 상기 아바카 섬유로 제1부직포(1)를 구성하고, 상기 대마 섬유로 제2부직포(2)를 구성하여 합지하는 이유는, 두 섬유 모두 천연섬유로서 우수한 강도를 가지며, 엽맥 섬유와 인피 섬유의 조합을 통해 강도, 중량 등의 기계적 물성을 높이면서도, 항균성, 탈취성 등의 기능성을 높이기 위함이다. 더욱 구체적으로 아바카 섬유로 구성된 제1부직포(1)만으로 마감재를 구성할 경우, 마감재로서 요구되는 물성을 갖지 못하는 것은 물론, 탈취, 항균성이 부족하게 되며, 대마 섬유로 구성된 제2부직포(2)만으로 마감재를 구성할 경우 내구성이 좋지 못하고, 흡수성이 부족하여 실내 습도 조절능력이 약해지는 등의 단점이 있기 때문이다.The reason for laminating the first nonwoven fabric 1 with the abaca fibers and the second nonwoven fabric 2 with the hemp fibers in the present invention is that both fibers have excellent strength as natural fibers, and leaf vein fibers and This is to increase the functionality such as antibacterial and deodorizing properties while increasing mechanical properties such as strength and weight through the combination of bast fibers. More specifically, when the finishing material is composed only of the first nonwoven fabric 1 made of abaca fibers, it does not have the physical properties required as a finishing material, as well as lacks deodorization and antibacterial properties, and the second nonwoven fabric 2 composed of hemp fibers This is because, when the finishing material is composed of only the material, the durability is not good, and the indoor humidity control ability is weakened due to lack of water absorption.

상기 폴리아마이드 필름(3)은 상기 제1부직포(1)와 상기 제2부직포(2) 사이에 개재되어 상기 제1부직포(1)와 상기 제2부직포(2)를 접착, 결합시키는 역할을 한다. 또한, 상기 폴리아마이드 필름(3)을 통해 마감재로서의 적절한 물성 역시 부여한다.The polyamide film 3 is interposed between the first nonwoven fabric 1 and the second nonwoven fabric 2 to bond and bond the first nonwoven fabric 1 and the second nonwoven fabric 2 to each other. . In addition, proper physical properties as a finishing material are also provided through the polyamide film 3 .

상기 폴리아마이드 필름(3)은 친환경의 필름형 핫멜트 접착제로, 저온에서도 접착이 가능하다는 특징이 있다. 본 발명에서 상기 폴리아마이드 필름(3)의 연화점은 50~120℃ 정도임이 바람직한데, 연화점이 너무 낮을 경우 주변 환경의 온도가 다소 높아짐에 따라 접착제가 유체화될 수 있고, 연화점이 너무 높을 경우 간단한 발열체를 통해 연화점 이상의 온도를 공급할 수 없어 제조비용이 증가하기 때문이다.The polyamide film 3 is an eco-friendly film-type hot melt adhesive, and has a feature that it can be adhered even at low temperatures. In the present invention, it is preferable that the softening point of the polyamide film 3 is about 50 to 120 ° C. If the softening point is too low, the adhesive may be fluidized as the temperature of the surrounding environment becomes slightly higher, and if the softening point is too high, it is simple This is because a temperature higher than the softening point cannot be supplied through the heating element, thereby increasing the manufacturing cost.

이러한 필름형 핫멜트 접착제인 폴리아마이드 필름(3)은 시판 상품 중 어떠한 것이라도 사용 가능하며, 그 두께는 40~60㎛ 정도이면 족하다.The polyamide film 3, which is such a film-type hot melt adhesive, can be any of commercially available products, and its thickness is sufficient as long as it is about 40 to 60 μm.

상기와 같이 구성되는 본 발명의 삼을 이용한 바이오복합 마감재는, 폐기시 자연부식되어 환경피해가 전혀 없고, 인체 유해물질을 배출하지 않으며, 항균성 및 탈취성이 우수하여 마감재로서 유용하게 사용될 수 있다는 장점이 있다.The bio-composite finishing material using hemp of the present invention configured as described above is naturally corroded when discarded, so there is no environmental damage, does not emit harmful substances to the human body, and has excellent antibacterial and deodorizing properties, so that it can be usefully used as a finishing material. There is this.

한편, 본 발명의 바이오복합 마감재는 제1, 2부직포(1)(2)와 폴리아마이드 필름(3)만으로 구성되므로, 마감재로서 사용시 기계적 물성을 충족시키지 못하거나, 기타 자재와의 결합성이 좋지 못할 수 있는바, 이를 개선하기 위하여, 도 2에서와 같이, 제1부직포(1)의 하면 및 상기 제2부직포(2)의 상면에 폴리아마이드 필름(3')이 각각 추가로 접착되는 것이 바람직하다.On the other hand, since the biocomposite finishing material of the present invention consists only of the first and second nonwoven fabrics (1) and (2) and the polyamide film (3), it does not satisfy mechanical properties when used as a finishing material, or has poor bonding with other materials. In order to improve this, it is preferable that a polyamide film 3' is additionally attached to the lower surface of the first non-woven fabric 1 and the upper surface of the second non-woven fabric 2, respectively, as shown in FIG. 2 . do.

즉, 폴리아마이드 필름(3')을 통해 마감재의 강도, 내구성 등의 기계적 물성을 개선하여 그 활용성을 더욱 높이는 것이다. 여기서, 상기 폴리아마이드 필름(3')은 앞서 제1, 2부직포(1)(2) 사이에 개재된 폴리아마이드 필름(3)과 동일한 것을 사용하는바, 이에 대한 추가적인 설명은 생략한다. That is, by improving mechanical properties such as strength and durability of the finishing material through the polyamide film 3 ′, its utility is further increased. Here, the polyamide film 3 ′ is the same as the polyamide film 3 interposed between the first and second nonwoven fabrics 1 and 2 above, and a further description thereof will be omitted.

한편, 상기 마감재가 건축구조물의 벽면 또는 바닥재용 마감재로 적용될 경우, 더욱 우수한 단열성 및 항균성을 부여하기 위하여, 상기 제1부직포(1)에 커피찌꺼기가 더 포함되도록 구성할 수 있다.On the other hand, when the finishing material is applied as a finishing material for a wall or flooring of a building structure, in order to provide better thermal insulation and antibacterial properties, the first nonwoven fabric 1 may further contain coffee grounds.

상기 커피찌꺼기는 로스팅된 원두로부터 커피를 추출하고 남은 잔여물을 함수량 0.1~3%로 건조하여 입도가 1~20㎛ 정도가 되도록 분쇄한 것을 의미하는바, 상기 커피찌꺼기에는 셀룰로오스가 다량 함유되어 부직포의 소재로서 적합하고, 우수한 단열성능 역시 갖는다. 아울러, 이러한 커피찌꺼기는 테이크 아웃 커피전문점 등에서 다량 발생하여 처치가 곤란한바, 자원 재활용의 효과를 갖는 것은 물론, 폐기시 자연분해가 가능하여 환경오염을 야기하지 않는다는 장점이 있다.The coffee grounds mean that coffee is extracted from roasted beans and the remaining residue is dried to a moisture content of 0.1 to 3% and ground to a particle size of about 1 to 20 μm. The coffee grounds contain a large amount of cellulose and are non-woven It is suitable as a material for In addition, since such coffee grounds are generated in large amounts in takeaway coffee shops, etc., it is difficult to treat them, so it has the effect of recycling resources and has the advantage that it does not cause environmental pollution because it can be decomposed naturally when discarded.

이때, 그 사용량은 상기 아바카 섬유 100중량부에 대하여, 상기 커피찌꺼기 10~40중량부임이 바람직한바, 이는 그 기능성을 고려한 것이다. In this case, the amount used is preferably 10 to 40 parts by weight of the coffee grounds with respect to 100 parts by weight of the abaca fiber, which is in consideration of its functionality.

또한, 상기 제2부직포(2)의 항균성 및 탈취성을 더욱 개선하기 위하여, 대마 입자가 더 포함되도록 할 수 있다.In addition, in order to further improve the antibacterial and deodorizing properties of the second nonwoven fabric 2, hemp particles may be further included.

상기 대마 입자는, 대마의 항균성 및 탈취성을 더욱 극대화한 것으로, 대마의 뿌리를 건조하고, 상기 건조된 대마에 대마뿌리 추출물을 도포한 후, 냉동하여 파쇄한 것을 의미한다. 이러한 대마 입자는 제2부직포(2) 내 섬유 사이에 위치하여 현저히 우수한 항균 및 탈취성능을 발휘한다.The hemp particles, which further maximize the antibacterial and deodorizing properties of hemp, dry the hemp root, apply the hemp root extract to the dried hemp, and then freeze and crush it. These hemp particles are positioned between the fibers in the second nonwoven fabric 2 and exhibit remarkably excellent antibacterial and deodorizing performance.

상기 대마 입자의 제조방법을 더욱 구체적으로 설명하면, 대마의 뿌리를 온풍, 열풍, 냉풍 또는 자연건조 중 어느 하나의 방법으로 함수율이 5% 이하가 되도록 건조한다. 그리고 이에 대마뿌리 추출물을 도포한다. 그 도포량은 상기 대마의 뿌리와 대마뿌리 추출물이 100:1~10 중량비 정도이면 족하다. 다음으로, 이를 -50~-30℃에서 5~10시간 냉각한 후, 0.1~100㎛ 정도의 입도를 갖도록 파쇄하는 것이다. More specifically, the manufacturing method of the hemp particles is dried so that the water content is 5% or less by any one of warm air, hot air, cold air, or natural drying of the roots of hemp. And the hemp root extract is applied thereto. The application amount is sufficient if the cannabis root and hemp root extract are in a weight ratio of about 100:1 to 10. Next, after cooling it at -50 ~ -30 ℃ for 5 ~ 10 hours, it is crushed to have a particle size of about 0.1 ~ 100㎛.

상기 대마뿌리 추출물은 대마뿌리에 물을 가하고, 20~80℃에서 2~12시간 추출 후 여과한 것일 수 있는바, 이를 제한하지 않으며, 천연물로부터 추출물을 추출하는 공지의 방법을 적용하면 족하다. 또한, 필요에 따라 농축할 수 있음은 당연하다.The hemp root extract may be filtered after adding water to the hemp root and extracting at 20 to 80 ° C for 2 to 12 hours, without limitation, it is sufficient if a known method of extracting the extract from a natural product is applied. In addition, it is natural that it can be concentrated as needed.

이때, 상기 대마 입자의 사용량은 상기 대마 섬유 100중량부에 대하여, 10~40중량부임이 바람직한바, 이는 그 기능성을 고려한 것이다. In this case, the amount of the hemp particles used is preferably 10 to 40 parts by weight based on 100 parts by weight of the hemp fiber, which is in consideration of its functionality.
