Description

세탁성 및 이지 클리닝 특성이 우수한 천연가죽 소재의 제조방법 및 이 방법에 의해 제조된 천연가죽 소재{MANUFACTURING METHOD OF NATURAL LEATHER MATERIAL HAVING EXCELLENT WASHING PROPERTY AND EASY CLEANING PROPERTY AND NATURAL LEATHER MATERIAL USING THE SAME}Manufacturing method of natural leather material with excellent washability and easy cleaning properties and natural leather material manufactured by this method

본 발명은 표면 장력 33dyne/cm 이하, 오염물과의 접촉각 100°이상을 가짐으로써 오염에 대한 저항성을 향상시키고, 이로 인해 우수한 세탁성 및 이지 클리닝 특성을 부여할 수 있도록 하는 천연가죽 소재의 제조방법 및 이 방법에 의해 제조된 천연가죽 소재에 관한 것이다.The present invention provides a method for manufacturing a natural leather material that improves resistance to contamination by having a surface tension of 33 dyne/cm or less and a contact angle with contaminants of 100° or more, thereby providing excellent washability and easy cleaning characteristics; and It relates to natural leather materials manufactured by this method.

일반적으로 신발, 가방, 가구의 주요 소재로 사용되는 가죽은 은면가죽(Grain leather)과 육면가죽(Split leather, 스플릿 가죽)로 구분되며, 국내의 중·저가의 신발, 가방, 가구 등에는 기모성을 가지고 있는 저가 원자재인 육면가죽을 주로 사용하고 있다.In general, leather used as the main material for shoes, bags, and furniture is divided into grain leather and split leather, and brushed leather is used in domestic mid- to low-priced shoes, bags, and furniture. We mainly use meat leather, which is a low-cost raw material.

가죽에 대한 연구는 주로 은면가죽과 도장가죽(Finished leather)에 대한 연구가 대부분이고, 기모(Nap)를 가지는 저급의 육면가죽에 대한 연구는 대부분 유연성, 터치성, 항균성 등에 대한 연구가 대부분이었으며, 그 이유는 육면가죽은 기모를 가지고 있어 도장이 어렵고, 일반적으로 염색만 한 상태로 제품화가 진행되기 때문이다.Most research on leather has been on silver-faced leather and finished leather, and most research on low-quality flesh-side leather with naps has been on flexibility, touchability, and antibacterial properties. This is because flesh leather has brushing, making it difficult to paint, and is generally commercialized in a dyed state.

최근에는 은면가죽보다 상대적으로 저렴한 원자재인 육면가죽에 대한 활용도가 증대하여 신발, 가방, 가구(소파)등 그 사용범위가 확대되고 있는 추세이나, 조직적인 특성으로 도장이 어려운 문제로 인해서 표면 가공이 거의 불가능하여 소비자 및 바이어들이 요구하는 기능성 부여에 어려움을 가지고 있고, 특히 천연가죽에서는 시도한 바 없는 세탁에 의한 오염물의 세척, 인위적인 오염에 대한 이지 클리닝(easy cleaning), 외부의 오염물에 대한 저항성을 가지는 소재의 기능성 개선에 대한 연구가 지속적으로 요구되고 있다.Recently, the use of six-faced leather, which is a relatively cheaper raw material than silver-faced leather, has increased, and its range of use has expanded to include shoes, bags, and furniture (sofas). However, surface processing is difficult due to the difficulty of painting due to its organizational characteristics. It is almost impossible, making it difficult to provide the functionality demanded by consumers and buyers. In particular, it has the ability to clean contaminants by washing, which has never been attempted with natural leather, easy cleaning against artificial contamination, and resistance to external contaminants. Research into improving the functionality of materials is continuously required.

이를 해결하기 위하여 특허문헌 1에서는 하나 이상의 플루오르화 우레탄, 하나 이상의 플루오르화 에스테르, 또는 이것들의 혼합물을 포함하는 조성물과 세탁가능한 피혁을 접촉시킴을 포함하는, 세탁가능한 피혁에 지속적인 발유성, 지속적인 제오성 및 지속적인 발수성을 부여하는 방법을 제안하였다.To solve this problem, Patent Document 1 discloses a method for imparting persistent oil repellency and persistent stain resistance to washable leather, which involves contacting the washable leather with a composition containing one or more fluorinated urethanes, one or more fluorinated esters, or a mixture thereof. and a method for providing continuous water repellency was proposed.

하지만, 상기 특허문헌 1과 같은 종래기술은 표면 장력 및 오염물과의 접촉각이 커짐에 따라 실제 세탁성 및 이지 클리닝 특성이 부여되지 못하는 문제점이 있었다.However, the prior art, such as Patent Document 1, had a problem in that actual washability and easy cleaning characteristics were not provided as the surface tension and the contact angle with contaminants increased.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 기모를 가지고 있는 육면가죽에 물리적 및 화학적인 가공 처리를 통해, 표면 장력 33dyne/cm 이하, 오염물과의 접촉각 100°이상을 가질 수 있도록 하여 오염에 대한 저항성을 향상시킴으로써, 우수한 세탁성 및 오염물이 쉽게 제거되는 이지 클리닝 특성을 부여하고, 이로 인해 천연가죽은 세탁이 불가능하다는 고정관념에서 벗어나 신발, 소파, 가방 등에 범용적으로 적용할 수 있도록 함을 과제로 한다.The present invention is intended to solve the above problems, through physical and chemical processing on brushed flesh leather, so that it can have a surface tension of 33 dyne/cm or less and a contact angle with contaminants of 100° or more, thereby preventing contamination. By improving the resistance to heat, it provides excellent washability and easy-cleaning characteristics that allow contaminants to be easily removed, thereby breaking away from the stereotype that natural leather cannot be washed and allowing it to be universally applied to shoes, sofas, bags, etc. Make it an assignment.

The fatliquoring step (S300) uses a fatliquoring solution containing a silicone-based waterproofing agent, and the capping step (S400) uses a capping solution containing a fluorine-based waterproofing agent.

보다 구체적으로 상기 버핑 단계(S100)는 천연가죽 표면의 기모(Nap)의 길이 등을 조절하기 위한 것으로, 육면가죽을 버핑(buffing) 처리하며, 보다 구체적으로 육면가죽의 표면을 샌드페이퍼(sandpapaer)를 이용하여 버핑처리한다. 여기서, 상기 샌드페이퍼는 셀(cell) 크기가 #120 ~ #240 등을 사용할 수 있으나 여기에 한정되는 것은 아니고 이미 공지된 다양한 샌드페이퍼의 사용이 가능하다.More specifically, the buffing step (S100) is for controlling the length of naps on the surface of natural leather, and the meat leather is buffed. More specifically, the surface of the meat leather is treated with sandpaper (sandpapaer). Buffing is done using. Here, the sandpaper may have a cell size of #120 to #240, but is not limited thereto, and various previously known sandpapers may be used.

상기 리탄닝 단계(S200)는, 육면가죽 내 콜라겐 성분의 메트릭스 내부에 리탄닝제를 침투시켜 처리함으로써 육면가죽의 방수성, 통기성 및 경량성 등을 향상시키기 위한 것으로, 상기 버핑 단계를 거친 육면가죽을 리탄닝 용액을 이용하여 리탄닝(retanning)처리하며, 보다 구체적으로 물 100 중량부에 대하여, 폴리머계 리탄닝제 10 ~ 13 중량부, 포름산나트륨(HCOONa) 1 ~ 3 중량부 및 탄산수소나트륨(NaHCO3) 0.1 ~ 0.3 중량부를 혼합한 리탄닝 용액 및 육면가죽을 드럼에 투입한 후, 40 ~ 50℃에서 120 ~ 130분간 회전시켜 리탄닝 처리한다.The retanning step (S200) is to improve the water resistance, breathability, and lightness of the meat leather by infiltrating and treating the inside of the matrix of the collagen component in the meat leather with a retanning agent. The meat leather that has gone through the buffing step is retanned. Retanning is performed using a tanning solution, and more specifically, based on 100 parts by weight of water, 10 to 13 parts by weight of a polymer-based retanning agent, 1 to 3 parts by weight of sodium formate (HCOONa), and sodium hydrogen carbonate (NaHCO 3) . ) 0.1 to 0.3 parts by weight of mixed retanning solution and meat leather are put into the drum and then rotated at 40 to 50°C for 120 to 130 minutes for retanning treatment.

The flesh leather that has gone through the retanning step is Fatliquoring is performed using a fatliquoring solution, and more specifically, for 100 parts by weight of water, 5 to 6 parts by weight of a silicone-based waterproof fatliquor, 5 to 6 parts by weight of a water repellent auxiliary, and 2 to 2.5 parts by weight of formic acid. After putting the mixed eggplant solution and meat skin into the drum, it is processed by rotating it at 50 ~ 60℃ for 90 ~ 100 minutes.

그리고, 상기와 같이 가지 처리가 완료되면 가지 용액을 드럼으로부터 배출시킨 다음 가지 처리한 육면가죽에 함침된 가지 용액이 제거될 수 있도록 3 ~ 4회 수세처리하고 건조시킨다.Then, when the branching treatment is completed as described above, the branching solution is discharged from the drum, then washed with water 3 to 4 times and dried so that the branching solution impregnated in the branching-treated meat leather can be removed.

여기서, 상기 실리콘계 방수 가지제는 AZ-601(피엔에스사) 등을 사용할 수 있고, 발수 보조제는 PQX(피엔에스사) 등을 사용할 수 있으나 반드시 여기에 한정되는 것은 아니고 이미 공지된 다양한 실리콘계 방수 가지제 및 발수 보조제의 사용이 가능하다.Here, the silicone-based waterproofing fatliquor may be used such as AZ-601 (PNS), and the water-repellent auxiliary may be used as PQX (PNS), etc., but is not necessarily limited thereto and may include various already known silicone-based waterproofing fatliquors. It is possible to use chemicals and water repellent auxiliaries.

한편, 상기 가지 용액의 조성비 및 처리 조건이 상기 범위를 벗어날 경우 가지 처리 효과가 미비해질 우려가 있다.On the other hand, if the composition ratio and processing conditions of the eggplant solution are outside the above range, there is a risk that the eggplant treatment effect may be insufficient.

More specifically, with respect to 100 parts by weight of water, After adding the capping solution and meat leather mixed with 3 to 3.5 parts by weight of fluorine-based or silicone-based waterproofing agent, 2 to 2.5 parts by weight of capping agent, and 0.1 to 0.3 parts by weight of formic acid into the drum, the mixture is heated at 50 to 60°C for 90 to 90 minutes. Rotate for 100 minutes and cap.

그리고, 상기와 같이 캡핑 처리가 완료되면 캡핑 용액을 드럼으로부터 배출시킨 다음 캡핑 처리한 육면가죽에 함침된 캡핑 용액이 제거될 수 있도록 3 ~ 4회 수세처리하고 건조시킨다.When the capping treatment is completed as described above, the capping solution is discharged from the drum, and then the capped meat leather is washed with water 3 to 4 times and dried to remove the capping solution impregnated.

여기서, 상기 불소계 방수제는 WR-5910(다락사) 등을 사용할 수 있으며, 실리콘계 방수제는 CK-104(다락사) 등을 사용할 수 있고, 캡핑제는 Tankrom-AB(Sisecam Chemicals 사) 등을 사용할 수 있으나 반드시 여기에 한정되는 것은 아니고 이미 공지된 다양한 불소계 방수제, 실리콘계 방수제 및 캡핑제의 사용이 가능하다.Here, the fluorine-based waterproofing agent may be used such as WR-5910 (Atticsa), the silicone-based waterproofing agent may be used such as CK-104 (Atticsa), and the capping agent may be used such as Tankrom-AB (Sisecam Chemicals).
