Translated fromKorean이 발명은 원단에 미세먼지가 흡착 및 흡수되는 것을 방지하는 성능을 가지는 섬유용 초발수 용액과 이를 이용한 초발수 원단의 제조 방법에 관한 것으로, 더욱 자세하게 설명하자면, 오물로 인한 오염의 제거 및 사용에 의해 저하되는 초발수성을 재생하는 방법을 포함하는 초발수 용액과 이를 이용한 초발수 원단에 대한 것이다.The present invention relates to a super-water-repellent solution for fibers having a performance of preventing fine dust from being adsorbed and absorbed on a fabric and a method of manufacturing a super-water-repellent fabric using the same, to be described in more detail, to remove and use contamination caused by dirt. It relates to a super water-repellent solution and a super-water-repellent fabric using the same, including a method of regenerating the super water-repellent property deteriorated by.
초발수 표면기술은 표면의 젖음(wetting)현상을 조절하기 위한 표면 개질(surface modification) 기술의 한 분야로, 고체 표면상에서 이루어지는 물방울의 접촉각이 150° 이상인 것을 의미하며, 이러한 발수성은 대체로 표면의 거칠기와 표면 에너지로 인해 결정된다. 이는 연잎효과(Lotus effect)를 통해 익히 알려져 있으며, 레저 및 아웃도어, 스포츠 의류 시장의 확대로 인해 발수성 직물의 필요성이 증가하면서 발수성 구현에 관한 연구가 활발히 진행되고 있는 실정이다.Super water-repellent surface technology is a field of surface modification technology for controlling the wetting phenomenon of a surface, which means that the contact angle of water droplets formed on a solid surface is 150 ° or more, and such water repellency is generally roughness of the surface. And surface energy. This is well-known through the Lotus effect, and the need for water repellent fabrics has increased due to the expansion of the leisure, outdoor, and sports apparel markets, and research on implementing water repellency has been actively conducted.
지금까지 각종 소재의 표면에 초발수 표면을 구현하기 위하여 표면의 에너지가 낮은 불소화합물을 사용하였다. 대한민국특허출원 제 10-2001-0065617호는 표면 프렉탈 구조(fractal structure)를 갖고 ㎚ ∼ ㎛ 크기의 세공을 갖는 무기 지지체 표면에 아조계 염화실란을 고착화 한 후, 불소계 단량체를 주요 단량체로 하여 기능성 단량체를 표면으로부터 라디칼 중합함으로써 표면에 초발수 효과와 같은 표면 특성을 지니는 유/무기 복합막에 대한 것으로 이 또한 불소화합물을 사용하는 좋은 예로 들 수 있다.To date, fluorine compounds with low energy on the surface have been used to realize super water-repellent surfaces on the surfaces of various materials. Republic of Korea Patent Application No. 10-2001-0065617 is a functional monomer using a fluorine-based monomer as a main monomer after the azo-based silane is fixed on the surface of an inorganic support having a surface fractional structure and pores having a size of ㎚ to µm. By radical polymerization from the surface of the organic / inorganic composite membrane having a surface property such as a super water-repellent effect, this is also a good example of using a fluorine compound.
불소계 화합물은 비교적 고가임에도 불구하고 저농도, 소량 사용만으로도 그 성능이 우수하고, 타 재료인 실리콘 혹은 탄화수소계 화합물이 구현할 수 없는 탁월한 초발수성을 발휘하기 때문에 외부의 액상 오염과 접촉했을 때 매우 큰 접촉각을 나타내 초기 오염방지성이 매우 우수한 것으로 알려져 있다. 그러나 시간이 지남에 따라 물리적으로 침적되는 오염물질 때문에 최외곽 표면이 오염물질로 채워지게 되면서, 세정 시 소수성인 표면은 물과 반발력을 가지게 되어 부착된 오염물질의 제거가 용이하지 않게 되는 문제점이 발생한다.Although the fluorine-based compound is relatively expensive, its performance is excellent even at low concentrations and in small amounts, and it has a very large contact angle when it comes into contact with external liquid contamination because it exhibits excellent superhydrophobicity that other materials such as silicone or hydrocarbon compounds cannot realize. It is known that the initial anti-pollution property is very excellent. However, as the outermost surface is filled with contaminants due to contaminants that are physically deposited over time, a hydrophobic surface has a repelling force with water, and thus, it is difficult to remove the attached contaminants. do.
이러한 문제점을 해결하기 위하여 과불소알킬기를 함유하는 아크릴레트 또는 메타크릴레이트와 에틸렌옥사이드기가 부가된 탄화수소계 아크릴레이트 구조를 이용한 양성 고분자를 코팅하여 초기 오염방지성을 유지하며, 물로 세정 시 표면에서의 환경 대응형 관능기의 재배치가 발생하여 오염을 쉽게 제거하려는 연구 개발 노력이 있었으나, 상기한 방법으로 제조된 재료는 에멀젼 입자의 크기가 2~3㎛로 비교적 크기 때문에 기재와의 혼합 시 사용성 및 기재에 대한 침투성이 떨어진다는 문제가 존재하였다.In order to solve this problem, a coating of a positive polymer using an acrylate or methacrylate containing a perfluorinated alkyl group and a hydrocarbon-based acrylate structure added with an ethylene oxide group maintains the initial contamination prevention property, and when washed with water, There has been a research and development effort to easily remove the contamination due to the rearrangement of functional groups corresponding to the environment, but the material produced by the above-described method has a relatively large size of the emulsion particles of 2 to 3 μm, so it is useful in mixing with the substrate and the substrate. There was a problem of poor permeability to Korea.
또한 과불소알킬기 함유 코팅제의 경우 퍼플루오르옥탄술폰산(Perfluorooctane sulfonates, PFOS), 퍼플루오로옥탄산(Perfluorooctanoic acid, PFOA) 등 인체 및 환경에 유독한 물질이 포함되어있을 수 있다는 문제점이 존재하였다.In addition, in the case of the perfluorinated alkyl group-containing coating agent, there existed a problem that substances toxic to the human body and the environment, such as perfluorooctane sulfonates (PFOS) and perfluorooctanoic acid (PFOA), may be included.
이에 이 발명은 종래의 문제점을 해결하기 위한 것으로, 기재와의 혼합 시 침투가 용이하고, 인체 및 환경에 유독한 물질을 포함하지 않으면서도 초발수성을 지니며 원단 내부에 미세먼지가 흡수되는 것을 방지하는 기능을 지니는 섬유용 초발수 용액과의 이를 이용한 초발수 원단의 제조 방법을 제공하는 데 그 목적이 있다.Accordingly, the present invention is to solve the conventional problems, it is easy to infiltrate when mixed with the substrate, it has a super water repellency without containing toxic substances in the human body and the environment and prevents the absorption of fine dust inside the fabric An object of the present invention is to provide a method for manufacturing a super water-repellent fabric using the same as a super-water-repellent solution for fibers having a function to be performed.

이 때 사용되는 원단은 폴리에스테르, 나일론, 아크릴, 폴리우레탄, 아세테이트, 레이온, 폴리젖산, 아라미드, 폴리아미드의 화학섬유 및 면, 마, 견, 양모의 천연 섬유의 혼섬, 혼방, 교직품 중 하나이며, 직물, 편물, 부직포 등 어떠한 형태이어도 좋다. 그러나 원단은 깨끗한 상태여야 하며, 어떠한 유연제나 정련제 및 다른 케미컬을 포함하지 않는 것이 바람직하며, 그렇지 않은 경우 발수기능이 저하될 수 있으며, 욕조의 안정성에도 영향을 줄 수있어 바람직하지 않다.The fabric used at this time is one of polyester fiber, nylon, acrylic, polyurethane, acetate, rayon, polylactic acid, aramid, polyamide, chemical fiber and natural fiber of cotton, hemp, silk and wool. , And may be in any form such as woven fabric, knitted fabric, and non-woven fabric. However, the fabric should be in a clean state, and it is preferable not to include any softener, refining agent, and other chemicals, otherwise the water repellent function may be deteriorated, and it may also affect the stability of the bath, which is undesirable.
또한 원단을 산처리하는 단계(S100)는 포름산, 빙초산, 황산, 수산, 크롬산, 인산으로 이루어진 군에서 선택된 어느 하나로 구성된 욕조에서 이루어지며, 특히 포름산(Formic acid)을 이용하는 것이 바람직하다.In addition, the step (S100) of acid treatment of the fabric is made in a bath composed of any one selected from the group consisting of formic acid, glacial acetic acid, sulfuric acid, oxalic acid, chromic acid, and phosphoric acid, and it is particularly preferable to use formic acid.
또한 상기 욕조는 4.0~5.0의 산도로 이루어지면 바람직하며, 산도가 4.0 미만으로 떨어질 경우 원단의 산처리가 과하게 되어 원단의 수명이 극도로 짧아질 수 있어 바람직하지 않고, 산도가 5.0를 초과할 경우 산처리가 미비하여 원단 내에 이물질이 남아있을 수 있기 때문에 초발수 용액의 코팅이 바람직하게 이루어지지 않는 문제점이 있을 수 있어 바람직하지 않다. 또한 상기 산처리를 마친 원단은 5.5~6.5의 산도로 이루어지는 것이 바람직하며, 해당 산도를 만족하지 못할 경우 약제처리 단계(S200)에 영향을 미칠 수 있으므로 산처리 단계(S100)를 반복하여 실시할 수 있다.In addition, the bath is preferably made of an acidity of 4.0 to 5.0, and if the acidity falls below 4.0, the acid treatment of the fabric is excessive, and the life of the fabric may be extremely short, which is undesirable, and the acidity exceeds 5.0. Since the acid treatment is insufficient, foreign matter may remain in the fabric, which is undesirable because there may be a problem in that the coating of the super water-repellent solution is not preferably performed. In addition, it is preferable that the acid-treated fabric is made of an acidity of 5.5 to 6.5, and if the acidity is not satisfied, it may affect the drug treatment step (S200), so that the acid treatment step (S100) can be repeated. have.
또한 상기 약제처리를 거친 원단을 건조하는 단계(S300)는 110~150℃의 온도로 가열된 텐터기에서 이루어지는 것이 바람직하며, 온도가 110℃ 미만일 경우 충분한 건조가 이루어지지 않을 수 있어 바람직하지 않으며, 온도가 150℃를 초과할 경우 건조가 과하게 이루어지기 때문에 고착 단계(S400)를 거친 후 원단의 수명이 극도로 짧아질 수 있으므로 바람직하지 않다. 또한 상기 건조 단계(S300)를 마친 원단의 수분율은 50~60%인 것이 바람직하며, 해당 수분율을 만족하지 못할 경우, 원단 경화 시 원단의 수명에 영향을 미치거나, 충분한 경화가 이루어지지 않아 원단의 초발수성이 약화될 수 있어 바람직하지 않다.In addition, the step (S300) of drying the fabric subjected to the pharmaceutical treatment is preferably performed in a tenter machine heated to a temperature of 110 to 150 ° C, and when the temperature is less than 110 ° C, sufficient drying may not be performed, which is not preferable. When the temperature exceeds 150 ° C, drying is excessively performed, so after the fixing step (S400), the life of the fabric may be extremely short, which is not preferable. In addition, the moisture content of the fabric that has completed the drying step (S300) is preferably 50 to 60%, and if the moisture content is not satisfied, it affects the life of the fabric when curing the fabric, or sufficient curing is not performed, so that It is not preferable because superhydrophobicity may be weakened.
또한 상기 건조를 마친 원단을 가열하여 원단에 초발수성분을 고착시키는 단계(S400)는, 140~160℃의 온도로 가열된 텐더기에서 1~2분동안 이루어지는 것이 바람직하며, 더 바람직하게는 145~155℃, 더더욱 바람직하게는 148~152℃에서 이루어지는 것이 바람직하다. 140℃ 미만의 온도로 경화가 이루어질 경우, 초발수 용액의 경화가 충분하지 않아 초발수성이 떨어지는 문제가 있을 수 있어 바람직하지 않으며, 160℃를 초과하는 온도로 경화가 이루어질 경우 원단의 수명에 영향을 미칠 수 있어 바람직하지 않다. 또한 텐더기에서 원단이 경화되는 시간은 2분을 넘기지 않는 것이 바람직하며, 2분을 넘길 경우 원단의 수분률이 급감하면서, 초발수 용액과 원단 사이의 결합을 저하하므로 바람직하지 않다.In addition, the step of fixing the super water-repellent component to the fabric by heating the dried fabric (S400) is preferably made for 1 to 2 minutes in a tender machine heated to a temperature of 140 to 160 ° C, more preferably 145 It is preferably made at ~ 155 ° C, even more preferably at 148 ~ 152 ° C. When curing is performed at a temperature of less than 140 ° C, the superhydrophobic solution may not be sufficiently cured, which may cause a problem of poor water repellency, which is undesirable, and when curing at a temperature exceeding 160 ° C affects the life of the fabric. It is not desirable because it can be crazy In addition, it is preferable that the time for the fabric to cure in a tender machine does not exceed 2 minutes, and if it exceeds 2 minutes, the moisture content of the fabric decreases rapidly, and the bonding between the super water-repellent solution and the fabric decreases.
