Description

일라이트 부직포의 제조방법{method for manufacturing illite non woven fabric}Method for manufacturing illite nonwoven fabric

본 발명은 소취, 항균, 정수 및 정화기능 등이 우수한 일라이트(illite) 부직포의 제조방법에 관한것이다.The present invention relates to a method for producing an illite nonwoven fabric having excellent deodorization, antibacterial properties, water purification and purification.

일반적으로 공기조화기나 항온항습기, 공기여과기 또는 폐수처리장치등에는 소취, 항균, 정수 및 정화기능을 담당하는 필터가 설치되는데, 이와 같은 필터를 구성하는 구성품으로 부직포등이 널리 사용되고 있다.In general, air conditioners, thermo-hygrostats, air filters, or waste water treatment devices are provided with filters for deodorizing, antibacterial, water purification and purification functions, and nonwoven fabrics are widely used as components constituting such filters.

이러한 부직포 종류는 단섬유를 카딩 및 니들펀칭하여 제조한 단섬유부직포와 스펀본드(Spunbond) 또는 스펀레이스 공법으로 제조한 장섬유 부직포로 대별 할 수 있다.Such nonwoven fabrics can be broadly classified into short fiber nonwoven fabrics prepared by carding and needle punching short fibers and long fiber nonwoven fabrics produced by spunbond or spunlace methods.

종래 이러한 기능을 담당하는 부직포는 소취, 항균, 정수, 정화기능 등을 부여하기 위해 부직포에 소취가공 등과 같이 다양한 후가공 처리를 해오고 있다.Conventionally, nonwoven fabrics in charge of such functions have been subjected to various post-processing treatments such as deodorization, etc. to impart deodorization, antibacterial, water purification, and purification functions.

종래의 부직포 등의 항균성을 부여하는 소취, 항균 가공제로서는 2,4,4'-트리클로로-2'-하이드록시 디 페닐에테르(이르가산 DP-300 : 치바가이기사 상품명)가 제안되어 있다. 그러나 최근 이러한 2,4,4'-트리클로로-2'-하이드록시 디 페닐에테르를 사용하여 소취, 항균 가공된 섬유재료를 연소시키면 아주 독성이 높은 다이옥신 등이 생기는 것이 확인되어 사용이 중지되고 있다.As deodorizing and antimicrobial processing agents that impart antimicrobial properties such as conventional nonwoven fabrics, 2,4,4'-trichloro-2'-hydroxy diphenyl ether (Irga acid DP-300: Chiba-Gaiyi Co., Ltd. product) has been proposed. Recently, however, the use of 2,4,4'-trichloro-2'-hydroxydiphenyl ether to burn deodorized and antimicrobial processed fiber materials has resulted in the generation of highly toxic dioxins and has been discontinued. .

그래서 이를 대신한 소취, 항균 가공제로서 예를 들어 디메틸 벤질 라우릴 암모늄 클로라이드와 같은 제 4급 암모늄이나 3,5-디브로모살리실 아닐리드와 같은 페놀계 화합물이 제안되고 있으나, 세탁 내구성이 떨어지고 특히 염소계 세제를 사용할 경우 황변되는 문제가 발생된다.So instead of this, as a deodorizing and antibacterial processing agent, for example, quaternary ammonium such as dimethyl benzyl lauryl ammonium chloride or phenolic compounds such as 3,5-dibromosalicyl anilide have been proposed, but it has poor washing durability. The use of chlorine-based detergents causes yellowing.

이러한 이유로 일본 특개소 제54-38951호에는 이온 교환성 공중합체를 제조하여 동염 및 은염의 수용액으로 처리하여 섬유표면에 금속이온을 표출시켜 소취, 항균성을 부여한 경우도 있다. 그러나 이와 같은 방법도 금속이온이 고분자와 반응을 하여 물성이 저하되는 문제점이 생기게 된다.For this reason, Japanese Patent Application Laid-Open No. 54-38951 sometimes prepares ion-exchange copolymers and treats them with aqueous solutions of copper and silver salts to express metal ions on the fiber surface to impart deodorization and antibacterial properties. However, such a method also causes a problem that the metal ions react with the polymer, thereby deteriorating physical properties.

또한 한국 공고특허 93-12185호에서는 금속이온을 함유하는 무기세라믹을 방사원액에 첨가한 후 이를 방사하여 소취, 항균성을 갖는 폴리에스테르 원사를 제조한다. 이와 같은 방법은 방사공정 없이도 생산되는 천연섬유 재료에는 적용 할 수 없는 방법이다.In addition, Korean Patent Publication No. 93-12185 prepares a polyester yarn having deodorizing and antibacterial properties by adding inorganic ceramics containing metal ions to a spinning stock solution and then spinning them. This method is not applicable to natural fiber materials produced without the spinning process.

한국 공개특허 95-27021호에서는 키틴과 셀룰로오스를 용매중에 용해시킨 후이를 습식 방사시켜서 소취, 항균성을 갖는 셀룰로오스계 섬유를 제조한다. 이와 같은 방법도 별도의 방사공정을 거쳐야 하므로 공정이 복잡한 문제점이 있다.In Korean Laid-Open Patent Publication No. 95-27021, cellulose and cellulose are dissolved in a solvent and then wet-spun to prepare cellulose fibers having deodorant and antibacterial properties. This method also requires a separate spinning process, so there is a complicated process.

상기 종래 방법들은 요구기능이 다양해질수록 후가공 공정도 복잡해 지는 문제가 있고, 내구성이 낮아 후가공 공정으로 부여한 소취, 정수 등의 기능을 반영구적으로 계속 유지 할 수 없는 문제가 있다.The conventional methods have a problem that the post-processing process is also complicated as the required functions are diversified, and there is a problem that the durability, such as deodorization and water purification imparted to the post-processing process, cannot be maintained permanently.

따라서 사용기간이 길어질수록 요구기능의 효과가 점점 저하하게 된다. 아울러, 상기 종래 방법으로는 각종 용도에 따라 부직포에 요구되는 기능들을 근본적으로 충족 할 수 없는 문제도 있다.Therefore, the longer the period of use, the less effective the required function. In addition, there is a problem that the conventional method cannot fundamentally satisfy the functions required for the nonwoven fabric according to various uses.

또한 현재 공기청정기나 공기조화기에서 공기여과기의 여과재로 사용되는 물질로는 카본(carbon), 즉 활성탄이 쓰이고 여기에 사용되는 활성탄은 공기 중의 오염가스를 흡착 시키기 위해 사용되고 있으며, 여과재로 사용되는 카본은 필터 자체에서 발생되는 분진에 의해 여과기에서의 사용이 제한되어 있다.In addition, the material used as the filter medium of the air filter in the air cleaner or air conditioner is currently used carbon, that is, activated carbon is used to adsorb polluting gases in the air, carbon used as filter medium The use of silver in the filter is limited by dust generated in the filter itself.

이러한 문제 때문에 일라이트를 공기의 여과재로 사용되는 것이 제안 되고 있는데, 이 필터는 부직포로 패드의 형태로 만들고, 과립상태의 일라이트를 패드 안에 집어넣어 니들펀칭한 후 바인더로 접착하여 사용되어지고 있다.For this reason, it is proposed to use illite as an air filter medium, and this filter is made of a nonwoven fabric in the form of a pad, and the granular illite is put into the pad, needle punched, and then bonded by a binder. .

그런데, 이러한 필터는 부피가 크고 무게가 무거울 뿐 아니라, 공기청정기나 공기조화기에서 필요로 하는 공기의 압력이 커지는 문제점과 공기의 분진들이 부직포-일라이트-부직포를 통과한 후에야 공기여과기의 다른 필터 유닛에 유입되기 때문에 공기여과기의 성능을 단축시키고 공기청정기나 공기조화기에서블로어(blower)의 성능을 향상시켜야 하는 문제점을 가지고 있다.However, these filters are not only bulky and heavy, but also increase the pressure of the air required by the air cleaner or air conditioner, and other filters of the air filter only after the dust of the air passes through the nonwoven fabric, the illite nonwoven fabric. Since it is introduced into the unit, there is a problem of shortening the performance of the air filter and improving the performance of the blower in the air cleaner or the air conditioner.

한편, 일라이트를 여과재로서 사용하는 다른 예로서, 폴리에스테르 칩을 용융한 후 일라이트와 함께 부직포 원사에 방사하여 필터를 제조하는 방법이 있으나, 필터에 도포되는 일라이트의 양이 현저히 적고, 방사단계에서 일라이트의 세공(細空)이 용융된 폴리에스테르로 막혀 필터의 성능을 저하시키는 문제점이 있다.On the other hand, as another example of using the illite as a filter medium, there is a method of manufacturing a filter by melting the polyester chip and spinning the non-woven yarn together with the illite, the amount of illite applied to the filter is significantly less, spinning In the step, there is a problem that the pores of the illite are clogged with the molten polyester to lower the performance of the filter.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 각종 공기조화장치 및 수처리 분야에서 사용되는 필터의 부직포에 일라이트를 포함하여 제조함으로써 우수한 소취, 항균, 정수 및 정화기능을 가지면서도 이전의 일라이트를 이용한 부직포보다 제조가 쉽고, 또한 각종 환경 오염내지는 시간의 경과에 따른 필터 성능의 저하를 막을 수 있는 일라이트 부직포의 제조방법을 제공하는데 있다.An object of the present invention for solving the above problems is to produce a non-woven fabric of the filter used in various air conditioning apparatus and water treatment field including the illite, while having excellent deodorization, antibacterial, water purification and purification function The present invention provides a method of manufacturing an illite nonwoven fabric that is easier to manufacture than a nonwoven fabric and that can prevent deterioration of filter performance over time due to various environmental pollution.

도 1은 본 발명의 제조방법을 보인 공정도이다.1 is a process chart showing a manufacturing method of the present invention.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.

먼저 본 발명에 사용되는 일라이트의 기본적인 물성을 설명하자면, 일라이트는 점토질 연질 운모광물이며, 삼층 인편상 구조로서 물에 풀었을 때는 견사 현상을 지닌 독특한 성질이 있고, 그 주성분 SiO2, Al2O3, K2O, FEO2등으로 된 황백색 합성광물이며, 물리 화학적 성질은 수중에서 다량의 용존 산소를 발산하는 효능이 있고, 또 수중에 용존하는 중금속 이온, 유기질 이온, 부폐유기질의 악취 등을 흡착하는 흡착성이 좋으며, 이 흡착성은 공기 중에서도 발휘되어 유독가스, 악취 제거제의 원료로 사용이 가능하여 국내 특허 공고번호 제96-12091호에 소개된 흡착 탈취제는 바로 이 일라이트를 주성분으로 하고 있을 정도이다.First, to explain the basic physical properties of the illite used in the present invention, the illite is a clay soft mica mineral, a three-layer scaly structure has a unique property with silk phenomenon when solved in water, its main components SiO 2 , Al 2 It is an off-white synthetic mineral made of O 3 , K 2 O, FEO 2, etc., and its physicochemical property is effective in dissipating large amount of dissolved oxygen in water, and heavy metal ions, organic ions, and organic waste odors. Adsorption deodorizing agent, which is adsorbed in the air, is exerted in the air and can be used as a raw material for toxic gas and odor removing agent.The adsorption deodorant introduced in Korean Patent Publication No. 96-12091 has this illite as the main ingredient. It is enough.

게다가 일라이트에는 무기 게르마늄이 150ppm 이상 함유되어 있어서 인체의 신진대사를 촉진시켜 주는 효능을 가지고 있다. 상기 일라이트의 독성가스 흡착 및 탈착 시험은 한국 표준과학연구원에서 CO와 H2S를 대상으로 하여 1996. 10. 21 ~ 11. 13 사이에 실험(시험번호 965-0925)한 결과, 상기 CO는 유속 10ml/min의 조건에서 15% 제거되었고, 흡착된 CO는 온도 280℃에서 탈착이 시작되는 것으로 나타났으며, 상기 H2O는 유속 10ml/min의 조건에서 100% 제거되었고, 흡착된 H2S의 탈착이 예측되는 결과로 나타났다.In addition, illite contains more than 150ppm of inorganic germanium, which has the effect of promoting the metabolism of the human body. The toxic gas adsorption and desorption test of the illite was conducted between October 21 and November 13, 1996 (Test No. 965-0925) of CO and H 2 S at the Korea Research Institute of Standards and Science. It was found that 15% was removed at a flow rate of 10 ml / min, and the adsorbed CO started desorption at a temperature of 280 ° C. The H 2 O was 100% removed at a flow rate of 10 ml / min, and the adsorbed H 2 was removed. Desorption of S was shown to be the expected result.

또, 같은 연구소에서 1995. 12. 7에 행해진 원적외선 분광 분포시험은 3~14㎛ 파장대의 원적외선 복사량이 229℃의 측정 온도에서 평균 82.98%로 나타나 원적외선 방사효능도 우수한 것으로 밝혀진 광물이다.In addition, the far-infrared spectral distribution test conducted on December 7, 1995 at the same laboratory shows that the far-infrared radiation in the 3 ~ 14㎛ wavelength range is 82.98% at the measurement temperature of 229 ° C.

상기와 같은 물성을 가지는 일라이트를 부직포에 첨가시킬 경우 그 조성 배합비에 따라 종래의 문제점을 해소시킬 수 있는데, 도 1은 이와 같은 방법의 제조공정을 나타낸 공정도이다. 개략적인 공정을 살펴보면 조성물 혼합단계와 가열교반단계와 회전건조단계와 용융방사단계로 이루어진 것임을 알수 있다. 보다 구체적으로 설명하자면 본 발명의 부직포의 제조방법은 고분자 재료인 섬유제조용 폴리에스테르칩에 일라이트를 배합 후 건조단계를 거쳐 용융방사시켜 부직포를 제조하여 이를 각종 공기조화장치 및 수처리 분야에서 사용되는 필터의 부직포로 제조하는 일라이트 부직포의 제조방법에 있어서, 주재료인 섬유제조용 폴리에스테르칩에 이를 포함한 전체 중량%에 대하여 3000 ~ 4500 메쉬의 미세분말 일라이트가 6wt% ~ 9wt%를 가지도록 혼합한 후 가열교반기 속에 넣고 130~200℃에서 1시간에서 2시간동안 교반한 후, 회전건조기에서 10-20분동안 회전시키면서 180~200℃로 가열하여 수분을 제거시키고, 이를 방사용 호퍼에 투입하고, 스크류방사기의 온도가 260~270℃에서 용융방사시키는 단계를 거친 후, 이후 통상의 부직포제조단계로 마무리하여 부직포를 제조하는 것을 특징으로 한다.상기 용융방사시키는 단계를 거친 후 통상의 부직포제조단계는 용융방사시켜 스테이플 파이버(SF) 상태로 만든 다음 이를 통상의 개면공정, 혼련공정, 소면공정, 접층공정, 니들펀칭과정등을 거쳐 부직포를 제조하는 단계를 말한다. 구체적인 단계별 공정은 일반적인 것이므로 생략한다.When the illite having the above physical properties is added to the nonwoven fabric, the conventional problem can be solved according to the composition blending ratio. FIG. 1 is a process diagram showing a manufacturing process of the method. Looking at the schematic process, it can be seen that the composition consists of mixing step, heating stirring step, rotary drying step and melt spinning step. More specifically, in the method of manufacturing the nonwoven fabric of the present invention, a nonwoven fabric is manufactured by blending an illite to a polyester chip for manufacturing a fiber material, followed by melt spinning through a drying step, and using the same in various air conditioners and water treatment fields. In the production method of the illite nonwoven fabric of the non-woven fabric, after mixing the fine powder illite of 3000 ~ 4500 mesh to 6wt% ~ 9wt% with respect to the total weight% including polyester chip for fiber manufacturing The mixture was put in a heating stirrer and stirred at 130 to 200 ° C. for 1 hour to 2 hours, and then heated at 180 to 200 ° C. while rotating for 10-20 minutes in a rotary dryer to remove moisture, which was put into a spinning hopper and screwed. After the spinning machine is melt-spun at a temperature of 260 to 270 ° C., the non-woven fabric is finished by the usual nonwoven fabric manufacturing step. After the melt spinning step, a conventional nonwoven fabric manufacturing step is melt spinning to make a staple fiber (SF) state, and then a general opening process, a kneading process, a carding process, a lamination process, and a needle punching. Refers to the process of manufacturing a nonwoven fabric through a process. The specific step-by-step process is general and will be omitted.

상기 조성에 투입되는 일라이트 분말의 크기는 미세할수록 좋은데, 보통 3000 ~ 4500 메쉬 정도의 미세분말로 가공하여 사용한다.The finer the size of the illite powder added to the composition is better, it is usually used to process the fine powder of about 3000 ~ 4500 mesh.

상기와 같이 미세분말로 일라이트를 가공하는 방법은 물에 분산시켜 체취하는 방법이 일반적이고, 이 밖에도 전기폭발법등을 이용하여 일라이트 세라믹을 나노 크기의 입자분말로 가공할 수도 있다.As described above, the method of processing the illite with fine powder is generally a method of dispersing it in water and sieving. In addition, the illite ceramic may be processed into nano-sized particle powder by using an electric explosion method.

하지만 본 발명에 사용되는 일라이트를 가공하는 방법 자체는 통상의 방법을 이용하여 입자크기만 미세하게 만들면 되는 것이고, 그와 같은 가공방법에 본 발명의 특허성이 있는 것은 아니다.However, the method itself for processing the illite used in the present invention only need to make the particle size fine using a conventional method, and such a processing method does not have the patentability of the present invention.

또한 미리 미세가공된 일라이트 분말이 있으면 이를 이용하여도 무방하다.In addition, if there is a finely processed illite powder may be used.

상기와 같이 전체조성에 대한 일라이트의 조성비를 한정한 이유는 함량비가6wt% 보다 적으면 부직포의 균감소율이나 탈취율등의 필터링 성능이 떨어지고, 9wt% 보다 많으면 부직포의 기공을 막거나, 세탁시(재활용시) 뭉쳐서 떨어지는 단점이 있기 때문이다. 가장 바람직한 수치는 8wt% 이다.The reason for limiting the composition ratio of the illite to the total composition as described above is that if the content ratio is less than 6wt%, the filtering performance such as the non-woven fabric's uniformity reduction rate or deodorization rate is lowered. This is because there is a disadvantage in that they fall together. The most preferable value is 8 wt%.

상기와 같은 방법으로 제조한 일라이트를 함유한 부직포의 성능은 다음과 같은 방법으로 그 우수성을 확인하였다.The performance of the nonwoven fabric containing the illite prepared by the above method was confirmed by the following method.
