And the layers are integrally bound to each other by the entanglement between the fibers constituting them. The indoor air purification filter for automobiles of the present invention is manufactured by sequentially stacking the three layers and then spraying water at high pressure thereto. The filter of the present invention sequentially collects the pollutant according to the particle size over three stages, and in particular, the final stage of the microfibrous layer 1 collects all of the micropollutant source, and thus has excellent air purification performance.
Description
본 발명은 자동차 실내공기 정화용 필터(이하 "캐빈 필터"라고 한다) 및 그의 제조방법에 관한 것이다.The present invention relates to an automobile indoor air purification filter (hereinafter referred to as a "cabinet filter") and a method of manufacturing the same.
종래 캐빈 필터(Cabin Filter)로는 도 2와 같이 기재층(1)과 멜트 브로운(Melt Blown) 타입의 미세섬유층(3)이 적층되어 있고, 그 위에 미세섬유층 보호를 위해 저중량의 스펀본드 기포로 제조한 커버시이트(4)가 적층된 3층 구조의필터가 주로 사용되어 왔다. 종래 캐빈 필터는 상기 기재층(1)과 미세섬유층(3) 및 커버시이트(4)를 적층한 다음, 여기에 초음파를 처리하여 제조 되었다. 상기 초음파 처리에 의해 미세섬유층(3)을 이루는 미세섬유 중 일부가 기재층(1)에 부분적으로 점(spot) 접착하게 되어 미세섬유층(3)과 기재층(1)은 일체(一體)로 된다. 상기 기재층(1)은 필터의 기본물성을 유지하면서 입자가 큰 오염원을 필터링하는 역할을 하며, 미세섬유층(3)은 주로 입자가 작은 오염원을 필터링하는 역할을 하게 된다. 그러나 종래 캐빈 필터의 경우 필터 내에 점(spot) 접착 자국이 존재함에 따라 전체 필터의 필터링 기능이 저하되는 문제가 있었다. 다시 말해 필터의 표면 중 점(spot) 접착된 부분은 필터링 기능을 수행하지 못하기 때문에 필터의 기능이 저하 되었다.As a conventional Cabin Filter, a base layer 1 and a melt blown type microfiber layer 3 are stacked as shown in FIG. 2, and a spunbond bubble having a low weight to protect the microfiber layer thereon. The three-layered filter in which the manufactured cover sheet 4 is laminated has been mainly used. Conventional cabin filter was manufactured by laminating the substrate layer (1), the microfiber layer (3) and the cover sheet (4), and then subjected to ultrasonic treatment thereto. By the ultrasonic treatment, a part of the microfibers forming the microfiber layer 3 is partially adhered to the base layer 1 so that the microfiber layer 3 and the base layer 1 are integrated. . The base layer 1 serves to filter the pollutant with large particles while maintaining the basic properties of the filter, and the microfiber layer 3 mainly serves to filter the pollutant with small particles. However, in the case of the conventional cabin filter, there is a problem in that the filtering function of the entire filter is degraded as spot adhesive marks exist in the filter. In other words, the spot-bonded part of the filter surface does not perform the filtering function, and thus the filter function is degraded.
또한 종래 캐빈 필터는 기재층(1)과 미세섬유층(3)에서만 오염원을 필터링 하기 때문에 필터의 교체시기가 너무 짧은 문제가 있었다. 구체적으로 기재층(1)에서 입자가 큰 오염원을 1차로 필터링한 다음 바로 미세섬유층(3)에서 중간크기의 입자 및 미세입자을 동시에 모두 필터링 하기 때문에 미세섬유층(3)에 퇴적되는 오염원이 많아지게 되고, 그로 인해 미세섬유층(3)의 교체시기가 단축되는 문제가 발생 하였다.In addition, the conventional cabin filter has a problem that the replacement time of the filter is too short because it only filters the contaminant in the base layer (1) and the microfiber layer (3). Specifically, since the primary source of large particles in the substrate layer 1 is first filtered, the microfiber layer 3 simultaneously filters both medium-sized particles and fine particles, thereby increasing the amount of contaminants deposited on the microfibrous layer 3. , Thereby causing a problem that the replacement time of the microfiber layer 3 is shortened.
본 발명은 이와 같은 종래의 문제점들을 해결하기 위하여 중간 크기 입자의 오염원을 필터링 할 수 있는 중간 웹층(2)을 기재층(1)과 미세섬유층(3) 사이에 적층시킨 3층 구조의 캐빈 필터를 제공하고자 한다. 또한 본 발명은 캐빈 필터의 필터링 효율이 향상 될 수 있도록 각 층들이 점(spot) 접착 방식이 아니라 섬유들 간의 엉킴현상에 의해 서로 결착되는 캐빈 필터를 제공한다. 아울러 본 발명은 기재층(1), 중간 웹층(2) 및 미세섬유층(3) 들이 이들을 구성하는 섬유 상호간의 엉킴현상에 의해 서로 결속되도록 하는 방법을 제공한다.The present invention provides a three-layer cabin filter in which an intermediate web layer (2) capable of filtering the contaminant of medium size particles is laminated between the base layer (1) and the microfiber layer (3) in order to solve the conventional problems. To provide. In another aspect, the present invention provides a cabin filter in which each layer is bound to each other by the entanglement between the fibers, not the spot adhesion method so that the filtering efficiency of the cabin filter can be improved. In addition, the present invention provides a method for the base layer (1), the intermediate web layer (2) and the microfiber layer (3) to bind to each other by the entanglement between the fibers constituting them.

이와 같은 과제들을 달성하기 위한 본 발명의 자동차 실내공기 정화용 필터는, 1.0데니어 이하의 미세섬유로 이루어진 미세섬유층(3), 1∼15데니어의 섬유로 이루어진 웹층(2) 및 기재층(1)이 순차적으로 적층되어 있으며, 상기 각 층들이 이들을 구성하는 섬유 상호간의 엉킴 현상에 의해 서로 일체(一體)로 결속되어 있는 것을 특징으로 한다.In order to achieve the above problems, the indoor air purification filter for automobiles includes a microfiber layer 3 made of microfibers of 1.0 denier or less, a web layer 2 made of fibers of 1 to 15 deniers, and a base layer 1. It is laminated | stacked sequentially, It is characterized by the said each layer being united integrally with each other by the entanglement phenomenon of the fiber which comprises these.
또한 본 발명의 캐빈 필터 제조방법은 부직포, 직물, 메쉬 또는 스크림(Scrim) 중에서 선택된 기재층(1), 1∼5데니어의 섬유로 이루어진 웹층(2) 및 1.0데니어 이하의 미세섬유로 이루어진 미세섬유층(3)을 순차적으로 적층한 다음, 여기에 고압(High press)의 물(Water)을 분사시켜 이들을 결속시킴을 특징으로 한다.In addition, the cabin filter manufacturing method of the present invention is a nonwoven fabric, woven fabric, mesh or scrim (Scrim) base layer (1) selected, a web layer consisting of 1 to 5 denier fibers (2) and a microfiber layer consisting of fine fibers of 1.0 denier or less After stacking (3) sequentially, it is characterized in that the high pressure (Water) is sprayed on them to bind them.
이하 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.
먼저 본 발명의 필터는 1.0데니어 이하의 미세섬유로 이루어진 미세섬유층(3), 1∼15데니어의 섬유로 이루어진 웹층(2) 및 기재층(1)이 순차적으로 적층되어 있다.First, in the filter of the present invention, a microfiber layer 3 made of microfibers of 1.0 denier or less, a web layer 2 made of fibers of 1 to 15 denier, and a base material layer 1 are sequentially stacked.
상기 미세섬유층(3)은 미세한 데니어를 갖는 단섬유 또는 장섬유로 구성되며, 멜트 브로운(Melt blown) 형태인 것이 더욱 바람직 하다. 상기 미세섬유층(3)을 구성하는 미세섬유는 폴리올레핀수지, 폴리아미드수지, 레이온 또는 폴리에스테르 수지 등이다. 상기 미세섬유층은 최종적으로 미세 입자의 오염원을 필터링하는 역할을 한다. 미세섬유의 섬도가 1.0데니어를 초과할 경우에는 미세입자의 오염원을 효율적으로 포집 할 수 없게 된다.The microfiber layer 3 is composed of short fibers or long fibers having a fine denier, and more preferably in the form of a melt blown. The microfibers constituting the microfiber layer 3 are polyolefin resin, polyamide resin, rayon or polyester resin. The microfibrous layer finally serves to filter the pollutant of the fine particles. If the fineness of the fine fibers exceeds 1.0 denier, it becomes impossible to efficiently collect the pollutants of the fine particles.
상기 웹층(2)은 단섬유 웹(Web), 다시말해 카딩기를 거쳐 제조된 단섬유 웹(Web) 또는 스펀본드(Spun bond) 타입이다. 상기 웹층(2)은 중간크기 입자의 오염원을 포집하는 역할을 한다. 웹층(2)을 구성하는 섬유의 섬도가 1∼15데니어를 초과하는 경우에는 중간크기 입자의 오염원을 효율적으로 포집하기 어렵게 된다.The web layer 2 is of a short fiber web (Web), that is, a short fiber web (Web) or spun bond type manufactured through a carding machine. The web layer 2 serves to trap the pollutant of medium-sized particles. When the fineness of the fibers constituting the web layer 2 exceeds 1 to 15 deniers, it becomes difficult to efficiently collect the pollutant of medium-sized particles.
한편, 상기 기재층(1)은 부직포, 직물, 메쉬 또는 스크림(Scrim) 등으로서 필터의 기본 물성을 유지하면서 입자가 큰 오염원을 포집하는 역할을 한다.On the other hand, the base layer (1) serves as a non-woven fabric, woven fabric, mesh or scrim (Scrim) and the like to collect the pollutant with large particles while maintaining the basic properties of the filter.
본 발명의 자동차 실내공기 정화용 필터는 상기 기재층(1), 웹층(2) 및 미세섬유층(3)들이 이들을 구성하는 섬유 상호간의 엉킴현상에 의해 서로 일체(一體)로 결착되어 있는 것을 특징으로 한다. 그 결과 종래 점(spot) 접착 방식의 캐빈 필터와 비교시 필터링 효율이 증대된다.The indoor air purifying filter for automobiles of the present invention is characterized in that the base material layer 1, the web layer 2 and the fine fiber layer 3 are integrally bound to each other due to entanglement between the fibers constituting them. . As a result, the filtering efficiency is increased as compared with the conventional spot filter cabin filter.
이와 같은 본 발명의 캐빈 필터는 앞에서 설명한 기재층(1), 웹층(2) 및 미세섬유층(3)을 순차적으로 적층한 다음, 여기에 고압(High press)의 물(water)을분사시켜 제조한다. 마지막으로 제조된 필터에 정전처리 가공을 하는 것이 더욱 바람직 하다. 물 분사에 의해 각 층을 구성하고 있는 섬유들은 서로 엉키게 된다. 이와 같은 현상에 의해 상기 각 층들은 일체(一體)로 결착되어 진다.The cabin filter of the present invention is manufactured by sequentially stacking the substrate layer 1, the web layer 2, and the microfiber layer 3 described above, and then spraying water of high press thereon. . Lastly, it is more preferable to perform electrostatic treatment on the manufactured filter. By water spraying, the fibers constituting each layer are entangled with each other. By this phenomenon, each of the layers is integrally bound.
본 발명의 필터는 1단계로 기재층(1)에서 큰 입자의 오염원을 포집하고, 다음 2단계로 웹층(2)에서 중간크기 입자의 오염원을 포집하고, 마지막으로 미세섬유층(3)에서 미세오염원을 포집하게 된다. 그 결과 필터링 효과가 매우 우수함과 동시에 필터의 교체 주기도 길어지게 된다.The filter of the present invention collects the pollutant of the large particles in the substrate layer 1 in one step, collects the pollutant of the medium size particles in the web layer 2 in the next two steps, and finally the micropollution source in the microfiber layer 3. Will be captured. The result is a very good filtering effect and a long replacement cycle.
이하 실시예 및 비교실시예를 통하여 본 발명을 더욱 구체적으로 살펴본다. 그러나 본 발명이 하기 실시예에만 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited only to the following examples.
