Description
본 고안은 통기성이 있는 인조피혁에 관한 것으로, 그 목적은 인조피혁에 천연가죽과 같은 통기성을 부여하는것과, 생산원가를 절감하는것과, 천연가죽과 흡사한 부드러움과 내구성을 갖도록 함을 목적으로 한다.The present invention relates to a breathable artificial leather, the purpose of which is to give the artificial leather breathable like natural leather, to reduce the production cost, and to have the softness and durability similar to natural leather .
일반적으로 인조피혁은 피혁의 바닥부가 되는 직포,부직포등으로 되는 섬유포상에 수용성 용제로 용융된 폴리우레탄용액을 나이프코팅하여 피혁의 육부가 되는 속칭 은층을 형성하고 별도로 피혁무늬가 부각되어 있는 이형지에 폴리우레탄용액을 코팅하여 전자시트를 만들고 이 전자시트를 상기 은층위에 전사방식으로 접합한 다음 이를 수중에서 폴리우레탄용액을 응고시켜 수세한 다음 이형지를 제거하고 건조하여 표면에는 피혁 무늬 피막이 표현되고 그 하위에는 전사층과 은층이 결합된 피혁의 육층과 섬유층이 일체로 적층 형성된 인조피혁을 만들었다.In general, artificial leather knife-coated a polyurethane solution melted with a water-soluble solvent on a textile cloth, such as a woven fabric or a non-woven fabric, which is the bottom of the leather, to form a so-called silver layer serving as the skin of the leather, and on a release paper having a separate leather pattern Polyurethane solution is coated to make an electronic sheet, and the electronic sheet is bonded to the silver layer by transfer method, and the polyurethane solution is solidified in water, washed with water, then removed from release paper and dried to express a leather pattern coating on the surface. An artificial leather was formed by integrally laminating the meat layer and the fiber layer of the leather in which the transfer layer and the silver layer were combined.
이상과 같이 제조된 인조피혁은 다음과 같은 문제점이 있다.Artificial leather manufactured as described above has the following problems.
첫째, 이형지를 제거하지 않은 상태로 폴리우레탄 코팅층을 수중에서 응고 및 수세하기 때문에 이 과정에서 폴리우레탄 용제는 피혁무늬가 표현된 표층 쪽으로는 빠져나가지 못하고 섬유층 쪽으로만 빠져나가기 때문에 폴리우레탄 코팅층은 통기성이 없는 문제점이 있다.First, since the polyurethane coating layer is solidified and washed in water without removing the release paper, the polyurethane coating layer is breathable in this process because the polyurethane solvent does not escape to the surface layer where the leather pattern is expressed but only to the fiber layer. There is no problem.
둘째, 고가이면서 소모품인 이형지를 사용하므로 인하여 생산원가가 상승되는 문제점이 있다.Second, there is a problem that the production cost is increased due to the use of release paper, which is expensive and consumables.
셋째, 피혁의 육부가 되는 폴리우레탄층을 응고, 수세시 용제가 빠져나가는 것을 이형지가 방해하므로 표층에 미세기공 형성이 되지 않아 부드럽지 못할 뿐아니라 수세시 용제의 수세가 잘되지 않아 완제품후 상품이 변질될 우려가 있고, 따라서 내구성도 떨어지게 되는 문제점이 있다.Third, because the release paper prevents solidification of the polyurethane layer, which becomes the skin part of the leather, and the escape of the solvent during washing, the micropore is not formed on the surface layer, so it is not soft and the washing of the solvent during washing is not good. There is a risk of deterioration, and thus there is a problem that the durability is also reduced.
본 고안에서는 이상과 같은 종래의 문제점을 해결하기 위하여 섬유포 위에 피혁의 육부가 되는 폴리우레탄층을 친수성이 강한 수용성 용제를 사용하여 응고 수세시 인조모공이 형성되게 한 후 그 표면에 피혁 표층을 형성하되 종래와 같이 이형지를 사용하지 않고 묽은 폴리우레탄잉크를 그라비아 인쇄방법으로 인조모공이 막히지 않도록 엷게 반복 도포하여 건조하고, 이를 예비 가열한 후 표면에 롤러압인 방법으로 본 고안 목적에 대응하는 각종 가죽 무늬가 표현된 인조피혁을 완성하였다.In the present invention, in order to solve the conventional problems as described above, the artificial skin pores are formed on the surface of the polyurethane layer, which is a skin part of the leather, using a hydrophilic water-soluble solvent to form the surface of the leather on the surface thereof. As in the prior art, a thin polyurethane ink is applied by repeatedly applying thin polyurethane ink without releasing paper to prevent clogging of pores by gravure printing method, and after preheating, various leather patterns corresponding to the purpose of the present invention are applied by roller pressure on the surface. Completed artificial leather expressed.

본 고안을 첨부 도면에 의하여 공정별로 상세히 설명하면 다음과 같다.When the present invention is described in detail by process according to the accompanying drawings as follows.
제 1공정,1st process,
도 1의 예시와 같이 직포, 부직포 등으로 되는 섬유포를 가습통(200)에 침수되게 통과 시킨후 탈수롤러(201)에서 탈수하여 폴리우레탄액이 과하게 침투되지 않도록 가습된 섬유층(100)의 표면에 수용성 용제가 혼합된 폴리우레탄액을 나이프코팅수단(300)으로 코팅하여 피혁의 몸체가 되는 피혁육층(101)을 형성하고, 이를 저온수가 담겨있는 응고실(202)을 서서히 통과하는 동안 응고되면서 용제가 녹아 용출되어 내부에 연쇄다공질이 되도록 한다.As shown in FIG. 1, a fiber cloth made of a woven fabric, a nonwoven fabric, or the like is immersed in the humidification tank 200 and dehydrated in the dehydration roller 201 to the surface of the humidified fiber layer 100 so that the polyurethane liquid does not penetrate excessively. Polyurethane solution mixed with a water-soluble solvent is coated with a knife coating means 300 to form a leather layer 101 to become the body of the leather, while solidifying it while slowly passing through the coagulation chamber 202 containing the low-temperature water Is melted and eluted to be chain porous inside.
이때 용제가 융출된 미세공에는 그내부에 물이 흡습됨을 반복하여 상하가 서로 관통된 미세인조모공(102)이 형성된다.At this time, the fine pores 102 in which the solvent is melted and water is repeatedly absorbed therein to penetrate the top and bottom to form fine artificial pores 102.
본 공정에서 폴리우레탄의 용제는 주로 디메칠폴리아미드(DNF)를 사용하며, 다공질 숙성시간은 약 5 ~ 10분간 숙성후 수세실(203)에서 다공질부에 흡습탈수가 반복되게 수세하여 용제를 완전히 제거하므로서 다공질 형성이 정지되도록 한다.In this process, the solvent of polyurethane is mainly dimethyl polyamide (DNF), and the porous aging time is aged for about 5 to 10 minutes, and then the water-absorbing dehydration is repeatedly washed in the porous part in the washing room 203 to wash the solvent completely. This removes the porous formation.
제 2공정,2nd process,
도 2의 예시와 같이 상기 공정의 피혁육층(101) 표면에 그라비아 인쇄수단(400)으로 폴리우레탄 잉크를 엷게 도포하되, 상기 공정에서 생긴 미세인조모공(102)이 막히지 않도록 도포한 후 건조실(401)에서 건조함을 약 3∼4회 반복하여, 도 5의 예시와 같이 미세인조모공(102)이 메꾸어지지 않게 표면이 도포된 보강표층(103)을 형성한다.As shown in FIG. 2, the polyurethane ink is lightly applied to the surface of the leather layer 101 of the process by the gravure printing means 400, and the drying chamber 401 is coated so that the micro artificial pores 102 generated in the process are not blocked. Drying is repeated about 3 to 4 times, thereby forming a reinforcement surface layer 103 having a surface coated so that the micro artificial pores 102 do not fill as shown in FIG. 5.
이때 보강표층(103)을 형성하는 폴리우레탄 잉크에는 마모방지제, 파열방지제(초화멘), 성형성부여제(VMCH)와 색상표현을 위한 안료 등으로 조성되고, 건조실(401)은 70∼100℃의 열풍을 이용한다.At this time, the polyurethane ink forming the reinforcing surface layer 103 is composed of an anti-wear agent, a rupturing agent (manufactured men), a moldability imparting agent (VMCH), a pigment for color expression, and the like, and the drying chamber 401 has a Use hot air.
제 3공정,3rd process,
도 3의 예시와 같이 상기 공정에서 처리된 것을 피혁육층(101)과 보강표층(103)을 이루고 있는 폴리우레탄의 용융온도 보다 낮은 140∼150℃의 가열실(501)에서 예비 가열한 다음 가죽무늬가 표면에 표현된 압인수단(500)을 거처 보강표층(103) 표면에 가죽무늬가 압인된 인조피혁을 만든다.The pretreatment in the heating chamber 501 of 140 ~ 150 ℃ lower than the melting temperature of the polyurethane forming the leather layer 101 and the reinforcement surface layer 103 treated in the process as shown in the example of Figure 3 Through the stamping means 500 expressed on the surface of the reinforcement surface layer 103 to create a leather artificial leather stamped on the surface.
도면 중 미설명부호 301은 잉크공급수단, 302는 코팅용 나이프, 402는 전사롤러, 403은 잉크통, 501은 압인롤러, 502는 받침롤러이다.In the drawings, reference numeral 301 denotes an ink supply means, 302 denotes a knife for coating, 402 denotes a transfer roller, 403 denotes an ink container, 501 denotes a press roller, and 502 denotes a support roller.
이와같이 만들어진 인조피혁은 그 용도에 따라 왁스, 보강제 스프레이 등과 같은 끝손질을 선택적으로 실시한다.The artificial leather thus produced is selectively subjected to finishing such as wax, reinforcing agent spray, etc. according to the use thereof.
상기 공정에 의하여 제조된 본 고안 인조 피혁은 도 4와 도 5의 예시와 같이 인조모공(102)은 막히지 않고, 보강표층(103), 피혁육층(101), 섬유층(100)으로 적층 구성된다.The artificial leather of the present invention manufactured by the above process is made of laminated pores 102, the leather layer 101, and the fiber layer 100 without clogging the artificial pores 102 as shown in FIGS.
이상과 같이 제조된 인조피혁은 연쇄다공질에 의한 인조모공이 형성되어 있어 천연 피혁과 같이 통기성이 있는 효과가 있고, 종래와 같이 고가인 이형지를 사용하지 않게 되므로 생산원가를 절감할 수 있는 효과가 있고, 피혁 몸체가 되는 피혁육부는 연쇄다공질이 되고, 그 표면에는 보강표층을 형성함으로써 부드러우면서도 내구성이 있는 효과가 있다.The artificial leather manufactured as described above has artificial pores formed by a chain porous material, which has a breathable effect like natural leather, and does not use expensive release paper as in the prior art, thereby reducing the production cost. The leather body, which becomes the leather body, becomes a chain porous material, and its surface has a soft and durable effect by forming a reinforcing surface layer.
