극세사들이 3차원적으로 교락되어 있는 부직포와 상기 부직포내에 함침된 고분자 탄성체로 이루어진 인공피혁은 촉감, 라이트 이펙트, 드레이프성 등이 우수하고 천연피혁과 유사한 부드러운 질감과 독특한 외관을 갖고있어서 자동차, 비행기, 기차, 선박 등의 운송수단(이하 "차량"이라고 약칭한다)의 시트(Seat) 표피재나 인테리어 소재 등으로 널리 사용되고 있다.Artificial leather is composed of a nonwoven fabric in which microfibers are intertwined three-dimensionally and a polymer elastomer impregnated in the nonwoven fabric. The artificial leather has excellent feel, light effect and drape, and has a soft texture and unique appearance similar to that of natural leather. BACKGROUND ART It is widely used as a sheet skin material or interior material of a vehicle (hereinafter, referred to as "vehicle") for transportation such as trains and ships.
차량용 소재로 사용되는 인공피혁(이하"차량용 인공피혁"이라 약칭한다)은 마찰 및 외력에 대한 내구성 및 형태안정성이 요구됨과 동시에 굴곡이 많은 부위에 사용되는 특성상 봉제 및 장착 작업이 용이하도록 적절한 신율특성이 요구되고 있다. 또한 최근 인공피혁 소재를 고감성 소재로 인식하여 차량용으로의 적용이 날로 증가하는 추세에 있는데, 은은한 라이팅 이펙트와 같은 심미적 요소와 더불어 항균성과 소취성도 매우 중요해지고 있다.Artificial leather (abbreviated as "vehicle artificial leather") used as a vehicle material is required for durability and form stability against friction and external force, and is suitable for bending and mounting. This is required. In addition, recently, the artificial leather material is recognized as a highly sensitive material, and the application to the vehicle is increasing day by day, and antibacterial and deodorant as well as aesthetic elements such as a soft lighting effect are becoming very important.
인공피혁을 제조하는 종래 기술로 대한민국 등록특허 제0323637호에서는 단사 섬도가 0.1데시텍스 이하인 폴리아미드 극세섬유 다발들이 서로 엉켜져 있는 부직포와 상기 부직포내에 함유된 탄성중합체로 구성된 인공피혁 제조용 시트 및 상기 시트를 버핑 및 염색하여 제조한 인공피혁을 게재하고 있다.In the prior art of manufacturing artificial leather, Korean Patent No. 0323637 discloses a sheet for manufacturing artificial leather and the sheet comprising a nonwoven fabric in which polyamide microfiber bundles having a single yarn fineness of 0.1 decitex or less are intertwined with each other and an elastomer contained in the nonwoven fabric. Has published artificial leather produced by buffing and dyeing.
또한, 대한민국 등록특허 제0125109호에서는 해성분 용출 후의 단사섬도가 0.1데니어 이하가 되는 해도형 복합섬유를 단섬유화한 후, 이를 오프닝, 카딩, 크로스랩핑, 니들펀칭하여 부직포를 제조하는 제1공정과; 상기 부직포를 가열로울러로 압착하여 부직포를 평활화, 고밀도화하는 제2공정과; 카본블랙이 첨가된 폴리우레탄 용액을 상기 부직포에 함침한 후 응고시키는 제3공정과; 상기 부직포내 해성분을 용해, 제거하는 제4공정과; 해성분이 용출된 부직포를 버핑 및 염색하는 제5공정을 순차적으로 실시하여 인공피혁을 제조하는 방법을 게재하고 있다.In addition, the Republic of Korea Patent No. 0125109 is a first step of producing a nonwoven fabric by short-fiberized islands-in-sea composite fibers having a single yarn fineness of 0.1 denier or less after sea component elution, and opening, carding, cross-lapping, needle punching and ; A second step of smoothing and densifying the nonwoven fabric by compressing the nonwoven fabric with a heating roller; A third step of impregnating the polyurethane solution to which carbon black is added to the nonwoven fabric and then solidifying it; A fourth step of dissolving and removing the sea component in the nonwoven fabric; The fifth step of buffing and dyeing the nonwoven fabric from which the sea component is eluted is sequentially performed, and a method of manufacturing artificial leather is disclosed.
한편, 인공피혁에 항균성을 부여하는 종래기술로서 대한민국 공개특허 제2001-105991호에서는 인공피혁을 제조할때 무기계 항균제 등을 폴리우레탄 수지(탄성 중합체) 용액 내에 첨가한 후 이를 극세사로 이루어진 부직포에 함침하는 방법을 게재하고 있고, 대한민국 등록특허 제0658094호에서는 무기계 항균제를 인공피혁을 구성하는 극세섬유(도성분)내에 첨가하는 방법을 게재하고 있다.On the other hand, as a prior art that gives antimicrobial to artificial leather in Korea Patent Publication No. 2001-105991, when manufacturing artificial leather, an inorganic antimicrobial agent is added to a polyurethane resin (elastic polymer) solution and impregnated it in a non-woven fabric made of microfiber The Korean Patent No. 0658094 discloses a method of adding an inorganic antimicrobial agent into the ultrafine fibers (figure component) constituting artificial leather.
그러나, 상기의 종래방법들은 인공피혁에 항균성만을 부여할 뿐 소취성을 부여하지는 못하였는데, 항균성도 그 성능이 미흡하거나, 첨가되는 항균제의 평균직경이 상대적으로 커서 표면적이 감소하기 때문에 원하는 항균성을 얻기 위해서는 항균제의 첨가량을 늘려야 하므로 제조원가가 상승하고, 제조공정상의 문제들도 발생하였다.However, the above-mentioned conventional methods do not impart only antibacterial to artificial leather, but do not impart deodorization. The antimicrobial property also has insufficient performance, or the average diameter of the added antimicrobial agent is relatively large, so that the surface area is reduced to obtain the desired antimicrobial activity. In order to increase the amount of antimicrobial agent added, manufacturing costs have increased, and manufacturing problems have also occurred.
본 발명의 목적은 상기와 같은 항균제에서 발생하는 종래의 문제점들을 해결하고 동시에 소취성도 부여할 수 있는 차량용 인공피혁을 제공하기 위한 것이다.An object of the present invention is to provide a vehicle artificial leather that can solve the conventional problems occurring in the antimicrobial agent as described above and at the same time give a deodorant.
본 발명은 항균성과 동시에 소취성이 우수하고 원가가 저렴하고 제조공정이 용이한 차량용 인공피혁을 제공하고자 한다.The present invention is to provide a vehicle artificial leather excellent antibacterial and deodorant at the same time low cost and easy manufacturing process.
이하, 본 발명을 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.
먼저, 본 발명에 따른 인공피혁은 단사섬도가 0.001~0.3데니어인 극세섬유들이 서로 교락된 부직포내에 고분자 탄성체가 함침되어 있으며, 상기 고분자 탄성체내에 평균직경이 0.1~1.0㎛인 다공성 소취입자가 고분자 탄성체 전체중량대비 0.1~5중량% 함유되어 있는 것을 특징으로 한다.First, in the artificial leather according to the present invention, the polymer elastomer is impregnated in a nonwoven fabric in which microfibers having a single yarn fineness of 0.001 to 0.3 denier are intertwined with each other. It is characterized by containing 0.1 to 5% by weight relative to the total weight.
상기 다공성 소취입자의 주성분은 알루미노 실리케이트, 지르코늄 포스페이트, 카파 지르코늄 포스페이트, 실리카 등이며, 알루미노 실리케이트 계열인 제올라이트인 것이 보다 바람직하다.The main components of the porous deodorant particles are aluminosilicate, zirconium phosphate, kappa zirconium phosphate, silica and the like, and more preferably zeolites of aluminosilicate series.
다공성 소취입자 평균직경이 0.1㎛ 미만일 경우에는 제조공정이 관리가 어렵게 되고, 1.0㎛를 초과하면 표면적이 줄어들어 항균성 및 소취성의 개선효과가 저 하되고 폴리우레탄에 함침 작업성이 나빠진다.If the average particle diameter of the porous deodorant particles is less than 0.1㎛, the manufacturing process becomes difficult to manage, and if it exceeds 1.0㎛, the surface area is reduced, and the effect of improving antimicrobial and deodorizing properties is lowered and the impregnation workability of the polyurethane is worsened.
고분자 탄성체 전체중량대비 다공성 소취입자 함량이 0.1중량% 미만이면 항균성 및 소취성의 개선효과가 저하되고, 25중량%를 초과하면 함침 작업성이 나빠지고 촉감이 딱딱해지게 된다.If the content of the porous deodorant particles is less than 0.1% by weight relative to the total weight of the polymer elastomer, the effect of improving the antimicrobial and deodorant properties is lowered. If the content of the deodorant particles exceeds 25% by weight, the impregnation workability is poor and the feel becomes hard.
상기 다공성 소취입자 비표면적이 800㎡/g이상이고, 입자크기가 100~350nm 인 것이 바람직하다. 상기 다공성 제오라이트는 또한 은(Ag) 이온 및 아연(Zn) 이온 중에서 선택된 1종 이상이 결합되어 있는 것이 항균성 및 소취성 향상에 더욱 바람직하다.It is preferable that the specific surface area of the porous deodorant particles is 800 m 2 / g or more, and the particle size is 100 to 350 nm. The porous zeolite is also preferably combined with at least one selected from silver (Ag) ions and zinc (Zn) ions to improve antimicrobial and deodorant properties.
기존에 개발된 제오라이트는 입자크기가 350nm이상으로 크거나 입자간 응집현상으로 인하여 비표면적이 매우 낮았다. 상업화된 대표적인 제올라이트의 경우에 대부분 비표면적이 100㎡/g이하이고 최근에 타사에서 개발된 제오라이트의 경우에 650㎡/g수준으로 많이 개선된 사례가 있지만, 본 발명에 효과적으로 기여하기에는 미흡하였다. 본 발명에서는 입자크기를 350nm 이하로 합성하고 입자간 응집현상을 억제하므로써 비표면적이 800㎡/g 이상인 것을 인공피혁에 적용하였다. 여기에 항균성이 뛰어난 금속이온을 결합하므로써 항균성과 소취성을 동시에 갖도록 하였다.Previously developed zeolites have a specific surface area of 350 nm or more or a very low specific surface area due to coagulation. In the case of commercialized representative zeolites, the specific surface area is mostly 100 m 2 / g or less, and in the case of zeolites recently developed by other companies, there have been many improvements to the level of 650 m 2 / g, but it is insufficient to effectively contribute to the present invention. In the present invention, the specific surface area of 800 m 2 / g or more was applied to artificial leather by synthesizing the particle size to 350nm or less and suppressing the intergranular phenomenon. By combining metal ions with excellent antimicrobial properties, it has both antimicrobial and deodorant properties.
이와 같은 다공성 제오라이트를 제조하기 위해서는 수열합성법을 통해 350 나노미터 단위 입자크기의 Y형 제오라이트를 합성한 다음 여기에 항균성이 뛰어난 은, 아연 등 금속이온을 결합하는 공정 중 SiO2, Al2O3, Na2O, H2O 를 각각 10 : 1 : 4.3 : 135 몰비를 가지면서 5℃ 이하로 냉각된 시리카졸에 순수와 가성소다, Sodium Aluminate를 혼합하여 만든 용액을 가한 다음, 디스크형 스터러가 부착된 교반기를 이용해 300rpm 이상 고속으로 2시간 동안 회전/교반하여 나노크기의 입자를 얻는 것이 바람직하다.In order to manufacture such a porous zeolite, a Y-type zeolite having a particle size of 350 nanometers is synthesized by hydrothermal synthesis, and then SiO2, Al2O3, Na2O, H2O are combined in the process of combining metal ions such as silver and zinc having excellent antimicrobial properties. A solution made by mixing pure water, caustic soda, and sodium aluminate was added to the silica gel cooled to 5 ° C or less with a 10: 1: 4.3: 135 molar ratio, respectively, and then a high speed of 300 rpm or more using a stirrer with a disk stirrer. It is preferable to obtain nano-sized particles by rotating / stirring for 2 hours.
본 발명에서는 비표면적이 매우 크기 때문에 접촉표면적이 넓어서 항균성 및 소취성이 크게 개선된다. 입자 크기 또한 매우 작기 때문에 폴리우레탄 함침공정에 적용시 입자의 분산상태가 좋고 항균성 및 소취성의 크게 향상시킬 수 있다.In the present invention, since the specific surface area is very large, the contact surface area is large, which greatly improves the antibacterial and deodorant properties. Since the particle size is also very small, the dispersion state of the particles is good when applied to the polyurethane impregnation process and can greatly improve the antibacterial and deodorant properties.
입자크기가 250nm 이하이면 항균성 및 소취성 향상에 더욱 바람직하다.If the particle size is 250nm or less, it is more preferable for antibacterial and deodorant improvement.
상기 고분자 탄성체는 폴리우레탄 수지, 폴리우레아 수지 등이나, 가공성 측면에서 폴리우레탄 수지가 가장 바람직하다.The polymer elastomer is a polyurethane resin, a polyurea resin, or the like, and a polyurethane resin is most preferable in view of workability.
상기 극세섬유는 폴리아미드 섬유 또는 폴리에스테르 섬유 등이나, 본 발명에서는 극세섬유의 종류를 특별하게 한정하는 것은 아니다.The ultrafine fibers are polyamide fibers, polyester fibers, and the like, but the present invention does not specifically limit the kind of ultrafine fibers.
상기 극세섬유의 단사섬도는 0.001~0.3데니어 이다.Single yarn fineness of the ultrafine fibers is 0.001 ~ 0.3 denier.
단사섬도가 0.001데니어 미만인 경우에는 인공피혁의 강도가 저하되며, 0.3데니어를 초과하면 인공피혁의 촉감 및 라이팅 이펙트가 저하된다.If the single yarn fineness is less than 0.001 denier, the strength of the artificial leather is lowered. If the single yarn fineness is more than 0.3 denier, the touch and lighting effect of the artificial leather is lowered.
