이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시 예를 상세하게 설명하고자 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 1은 본 발명의 바람직한 일실시예에 따른 도전성 스웨이드 제조방법을 도시하는 흐름도이다.1 is a flowchart illustrating a method of manufacturing a conductive suede according to an exemplary embodiment of the present invention.

도 1에 도시된 바와 같이 본 발명에 따른 도전성 스웨이드의 제조방법은 내부 도전층 형성 단계와 상부 도전층 형성단계로 구분된다.As shown in FIG. 1, a method of manufacturing a conductive suede according to the present invention is divided into an inner conductive layer forming step and an upper conductive layer forming step.

먼저, 내부 도전층 형성단계는 1 내지 10% 중량비의 도전성 제제와 폴리우레탄 고형분 6 내지 20% 중량비로 혼합된 용제를 원단에 함침하고, 이를 맹글 단계, 건조 단계 및 연마 단계를 거쳐서 내부 도전층을 형성시키는 단계이다.First, the internal conductive layer forming step is impregnated with a solvent mixed with a conductive agent of 1 to 10% by weight and a polyurethane solid content of 6 to 20% by weight, and the internal conductive layer through the mangling step, drying step and polishing step Forming step.

이러한 내부 도전층을 형성시키는 단계는 폴리에스테르 트리코트(Polyester Tricot) 원단을 도전성 잉크를 사용한 1차 함침 단계와 일정한 도전성 잉크 함침율을 가지도록 하는 맹글을 이용한 맹글 작업 단계와 원단을 건조시키는 건조 단계와 원단을 연마하는 버핑 단계를 거친다.The step of forming the inner conductive layer is a first step of impregnating a polyester tricot (Polyester Tricot) fabric using a conductive ink and a mangling operation step using a mangle to have a constant conductive ink impregnation rate and a drying step of drying the fabric. And goes through a buffing step to polish the fabric.

도전성 잉크를 제조하기 위하여 도전성 제제로 카본 블랙을 사용하였으나 도전성 제제는 적어도 일부가 비금속성 도전성 제제 및 바인더를 포함하는 조성물로 현탁하게 혼합된 재료를 포함하게 된다. 이러한 도전성 제제는 함침된 재료의 일부에 도전성을 제공하기에 충분한 농도로 존재한다.Although carbon black was used as the conductive agent to prepare the conductive ink, the conductive agent includes a material in which at least a portion of the conductive agent is suspended and mixed in a composition including a binder. Such conductive agents are present at a concentration sufficient to provide conductivity to some of the impregnated materials.

또한, 이러한 도전성 제제는 비금속성 또는 금속성 또는 비금속성 도전성 제제는 중합체를 일수도 있다. 카본 블랙 도전성 제제를 사용하여 제조된 도전성 잉크는 내부 도전층 형성 과 상부 도전층 형성에 동일 농도의 잉크로 사용 할 수 도 있으며, 필요로 하는 저항에 따라 카본 블랙 도전성 제제의 농도를 달리하여 사용 할 수도 있다.Such conductive agents may also be nonmetallic or metallic or nonmetallic conductive agents may be polymers. The conductive ink prepared by using the carbon black conductive agent may be used as the ink of the same concentration for forming the inner conductive layer and the upper conductive layer, and may be used by varying the concentration of the carbon black conductive agent according to the resistance required. It may be.

다음으로, 상부 도전층 형성 단계는 상기 내부 도전층 위에 상부 도전층을 형성시키는 상부 도전층 형성 단계를 포함하는 것을 특징으로 한다.Next, the upper conductive layer forming step includes an upper conductive layer forming step of forming an upper conductive layer on the inner conductive layer.

도 2는 본 발명의 바람직한 일실시예에 따른 도전성 스웨이드의 제조방법을 도시하는 개념도이다.2 is a conceptual diagram illustrating a method of manufacturing a conductive suede according to a preferred embodiment of the present invention.

여기서, 상기 상부 도전층 형성 단계는 폴리우레탄 고형분 6 내지 20% 중량비와 도전성 제제 1 내지 10% 중량비로 혼합된 용제를 메시 롤과 코팅 나이프를 이용하여 함침시키고, 이를 열풍 건조기를 이용하여 건조시키는 건조 단계와 프린팅 단계를 포함한다.Here, the step of forming the upper conductive layer impregnated a solvent mixed in a polyurethane solid content of 6 to 20% by weight and a conductive agent 1 to 10% by weight by using a mesh roll and a coating knife, and drying it by using a hot air dryer Step and printing step.

상기 과정이 완료되면, 잉크가 도포된 원단을 열풍 건조기를 이용하여 건조시키는 2차 건조 단계를 거치게 된다.When the above process is completed, the ink-coated fabric is subjected to a secondary drying step of drying using a hot air dryer.

상기 2차 건조 단계는 원단의 지지 형태를 유지한 상태에서 최소한의 장력을 가한 후에 열풍 건조기를 이용하여 100 내지 130도씨에서 건조시키는 텐터 건조 과정을 거치는 것이 바람직하다.The secondary drying step is preferably subjected to a tenter drying process of drying at 100 to 130 degrees Celsius using a hot air dryer after applying a minimum tension in the state of maintaining the support form of the fabric.

마지막으로, 상기 프린팅 단계는 안료, 이염방지제, 유연제, 발수 첨가제 중 하나 이상을 원단에 프린팅하는 것을 특징으로 한다.Finally, the printing step is characterized in that printing one or more of the pigment, anti-inflammatory agent, softener, water repellent additive on the fabric.

이러한 공정이 완료된 스웨이드는 표면에 도전성을 가지게 된다. 스웨이드는 표면저항 약 1.0 * 106 /sq (Ohm per square) 미만 또는 약 1.0 * 105 /sq 미만 또는 약 1.0 * 104 /sq미만 또는 약 1.0 * 103 /sq 이다. The suede having such a process is conductive to the surface. Suede is less than about 1.0 * 10 6 / sq (Ohm per square) or less than about 1.0 * 10 5 / sq or about 1.0 * 10 4 / sq or less than about 1.0 * 10 3 / sq.

그리고 도전성 제제의 양을 선택 시에는 원하는 도전성이 고려되어야 한다. 또한, 표면저항 1.0 * 103 /sq 보다 우수한 도전성을 요구한다면 보다 많은 양의 전도성 제제를 혼합 사용하여 상기와 같이 동일한 방식의 작업을 수행하면 된다.And when selecting the amount of the conductive agent, the desired conductivity should be considered. In addition, if a higher conductivity than surface resistance of 1.0 * 10 3 / sq is required, a larger amount of conductive agent may be mixed to perform the same operation as described above.

도 3은 본 발명의 바람직한 일실시예에 따른 도전성 스웨이드 제조방법에 의해서 제조된 스웨이드 원단의 단면도이다.3 is a cross-sectional view of the suede fabric produced by the conductive suede manufacturing method according to an embodiment of the present invention.

도 3에 도시된 바와 같이 스웨이드 원단은 기모층(L3), 원단 지지층(L2) 및 뒷면 기모층(L1)으로 구분되며, 기모층(L3) 및 뒷면 기모층(L1) 양쪽에 기모 작업을 한 양면 기모 원단과 상기 기모층(L3) 한쪽에만 기모 작업을 한 단면 기모 원단을 사용할 수 있다.As shown in FIG. 3, the suede fabric is divided into a brushed layer (L3), a fabric support layer (L2), and a backed brushed layer (L1), and brushed on both the brushed layer (L3) and the backed brushed layer (L1). A single-sided brushed fabric that is brushed on only one side of the double-sided brushed fabric and the brushed layer (L3) can be used.

이상과 같이 본 발명은 도전성 스웨이드의 제조방법을 제공하는 것을 주요한 기술적 사상으로 하고 있으며, 도면을 참고하여 상술한 실시 예는 단지 하나의 실시 예에 불과하므로 본 발명의 진정한 범위는 특허청구범위에 의해 결정되어야 한다.As described above, the present invention has a main technical idea to provide a method for manufacturing a conductive suede, and the embodiment described above with reference to the drawings is only one embodiment, so the true scope of the present invention is defined by the claims. It must be decided.
