이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시 예를 상세하게 설명하고자 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 바람직한 일실시예에 따른 도전성 인공피혁의 제조방법을 도시하는 순서도이다.1 is a flowchart showing a method of manufacturing conductive artificial leather according to a preferred embodiment of the present invention.
도 1에 도시된 바와 같이 본 발명에 따른 도전성 인공피혁의 제조방법은 원단 준비 단계, 제1용제 배합 단계, 함침 단계, 맹글 단계, 제2용제 도포 및 코팅 단계, 건조 단계 및 엠보싱 단계를 포함한다.As shown in FIG. 1, the method for manufacturing conductive artificial leather according to the present invention includes a fabric preparation step, a first solvent compounding step, an impregnation step, a mangling step, a second solvent application and coating step, a drying step and an embossing step .
먼저, 도전성 인공피혁을 제조하기 위한 원단으로 폴리에스테르 트리코트(Polyester Tricot) 원단을 이용하는 것이 바람직하며, 사용 용도에 따라서 다양한 종류의 인공 피혁을 이용할 수도 있다.First, it is preferable to use a polyester tricot fabric as a fabric for producing conductive artificial leather. Various types of artificial leather may be used depending on the use.
다음으로, 제1용제 배합 단계에서 사용되는 도전성 제제로 카본 블랙을 사용하였으나 도전성 제제는 적어도 일부가 비금속성 도전성 제제 및 바인더를 포함하는 조성물로 현탁하게 혼합된 재료를 포함하게 된다. 상기 도전성 제제는 함침된 재료의 일부에 도전성을 제공하기에 충분한 농도로 존재한다.Next, although carbon black is used as the conductive agent used in the first solvent compounding step, the conductive agent will include a material that is suspended and mixed with a composition including at least a part of a non-metallic conductive agent and a binder. The conductive formulation is present at a concentration sufficient to provide conductivity to a portion of the impregnated material.
또한 도전성 제제는 비금속성 또는 금속성 또는 비금속성 도전성 제제는 중합체 일수도 있다.The conductive agent may also be a non-metallic or metallic or non-metallic conductive agent.
카본 블랙 도전성 제제를 사용하여 제조된 제1용제는 도전성 제제 1 내지 10% 중량비와 수성 폴리우레탄 고형분 6 내지 20% 중량비로 물과 혼합되어 점도 40 내지 1,000cP를 갖도록 제조한다.The first solvent prepared using the carbon black conductive agent is prepared to have a viscosity of 40 to 1,000 cP by mixing the conductive agent with water at a weight ratio of 1 to 10% and an aqueous polyurethane solid content of 6 to 20% by weight.
여기서, 중요한 점은 종래의 도전성 인공 피혁의 제조 방법과 달리 수분 폴리우레탄 고형분을 이용하고 이를 물과 혼합하여 도전성 제제를 제작한다는 점이다.The important point is that, unlike the conventional method for producing conductive artificial leather, a water-based polyurethane solid is used and mixed with water to prepare a conductive agent.
따라서, 종래의 디메틸포름아미드의 사용을 방지할 수 있다. 다만, 충분한 도전성을 확보하기 위해서 다음 단계를 필수적으로 거쳐야 한다.Thus, the use of conventional dimethylformamide can be prevented. However, the following steps are essential to ensure sufficient conductivity.
상기 방식으로 제조된 제1용제에 원단이 함침되면 맹글 단계를 거치게 되고, 제2용제라 원단의 상부면에 도포된다.When the first solvent prepared in this manner is impregnated with a fabric, it is subjected to a mangling step and is applied to the upper surface of the second solvent la fabric.
여기서 제2용제는 도전성 제제 1 내지 20% 중량비와 수성 폴리우레탄 고형분 20 내지 50% 중량비로 물과 혼합되어 점도 2,000 내지 20,000cP를 갖는 것이 바람직하며, 상기 제2용제의 점도를 조절하기 위해서 수성용 점정제를 이용하는 것이 바람직하다. 여기서, 제1용제 및 제2용제는 동일 저항의 범위 내에서 제조되는 것이 바람직하다.The second solvent is preferably mixed with water at a weight ratio of 1 to 20% by weight of the conductive agent and 20 to 50% by weight of an aqueous polyurethane solid to have a viscosity of 2,000 to 20,000 cP. In order to control the viscosity of the second solvent, It is preferable to use a point refining agent. Here, it is preferable that the first solvent and the second solvent are produced within the same resistance range.
이러한 제2용제는 코팅 나이트를 통해서 0.1 내지 0.3 mm 두께로 제2용제를 코팅하여 원단의 상부에 상부 도전층을 형성시키는 코팅 단계를 거치게 된다.The second solvent is coated with a second solvent through the coating knit to a thickness of 0.1 to 0.3 mm to form a top conductive layer on the top of the fabric.
나이프의 간격을 조절하여 상부 도전층의 높이가 0.1 내지 0.3 mm 층이 형성 되도록 한다. 이는 제1 도전층(제1용제를 통해서 원단에 형성된)에서 형성된 표면의 요철과 표면 저항의 단절을 보완하고 또한 균일한 표면 저항을 위하여 나이프를 이용하게 된다.The interval of the knife is adjusted so that the height of the upper conductive layer is 0.1 to 0.3 mm. This compensates for the breakage of the surface irregularities and surface resistances formed on the first conductive layer (formed on the raw material through the first solvent) and uses knives for uniform surface resistance.
상기 과정을 거치게 되면, 열풍 건조기를 이용하여 원단을 건조시키는 건조 단계를 거치되고, 이때 상기 건조 단계는 원단의 지지 형태를 유지한 상태에서 최소한의 장력을 가한 후에 열풍 건조기를 이용하여 100 내지 130도씨에서 건조시키는 텐터 건조 과정을 거치는 것이 바람직하다.After the above process, the fabric is dried by using a hot air dryer. In this drying step, the fabric is supported at a minimum tension in a state of supporting the fabric, and then dried in a hot air drier at 100 to 130 degrees Celsius It is preferable to carry out a drying process of the tenter which is then dried.
이러한 건조 과정을 거친 원단은 150 내지 200 도씨로 가열된 롤러를 이용하여 상기 원단 상부면을 엠보싱하는 엠보싱 단계를 거친다.The fabric having undergone this drying process is subjected to an embossing step of embossing the upper surface of the fabric using a roller heated to 150 to 200 degrees Celsius.
즉, 상기 엠보싱 단계는 원단 표면의 불균일성을 보완하고 제품의 내부에 생긴 공극을 최소화하여 균일한 도전성을 가지도록 한다.That is, the embossing step compensates for the unevenness of the surface of the fabric and minimizes the voids formed inside the product, so that the embossing step has uniform conductivity.
상기 과정이 완료된 인공피혁은 표면에 도전성을 가지게 되며, 인공피혁의 표면저항 약 1.0 × 106 Ω/sq (Ohm per square) 미만이다.The finished artificial leather has conductivity on the surface and is less than about 1.0 x 10 6 Ω / sq (Ohm per square) of the artificial leather.
여기서, 도전성 제제의 양을 선택 시 원하는 도전성이 고려되어야 하며, 표면저항 1.0 × 102 Ω/sq 보다 우수한 도전성을 요구한다면 보다 많은 양의 도전성 제제를 혼합 사용하여 상기와 같이 동일한 방식의 작업을 수행하면 된다.Here, when the amount of the conductive agent is selected, the desired conductivity should be considered. If the conductivity is required to be higher than 1.0 × 10 2 Ω / sq, a larger amount of the conductive agent may be mixed to perform the same operation as described above .
도 2는 본 발명의 바람직한 일실시예에 따른 도전성 인공피혁의 제조 방법을 도시하는 개념도이다.2 is a conceptual diagram showing a method of manufacturing conductive artificial leather according to a preferred embodiment of the present invention.

여기서, 기모층(L3) 및 뒷면 기모층(L1) 양쪽에 기모 작업을 한 양면 기모 원단과 상기 기모층(L3) 한쪽에만 기모 작업을한 단면 기모 원단을 사용할 수 있다.Here, a double-sided brushed fabric subjected to a brushed operation on both of the brushed layer L3 and the back brushed layer L1 and a brushed fabric having a brushed layer on one side of the brushed layer L3 can be used.
