나아가, 이러한 절단형 원사는 칼라로 구현될 수도 있고, 이를 위해서는 염료보다는 안료로 상기 절단형 원사를 염색시킨 후 사용하는 것이 바람직하다. 이를 통하여, 상기 안료에 의해 염색된 절단형 원사는 면, 나일론, 레이온, 폴리, 울(양모) 등의 직물로 절단형 원사가 도출된 인공피혁 표면을 문지르는 경우 발생하는 이 염(crocking) 문제를 개선할 수 있는 효과가 있다. Furthermore, such a cut yarn may be embodied in a color, and for this purpose, it is preferable to use after dyeing the cut yarn with a pigment rather than a dye. Through this, the cut yarn dyed by the pigment is a crocking problem that occurs when rubbing the surface of the artificial leather derived from the cut yarn with a fabric such as cotton, nylon, rayon, poly, wool (wool), etc. There is an effect that can be improved.

본 발명은 이와 같은 절단형 원사(fiber)가 포함된 습식 은층용 폴리우레탄 합성수지 배합액을 함침된 부직포(410) 상면에 코팅시키으로써, 도 4에 나타난 바와 같은 코팅층(420)을 형성시키는 것이다. 여기서, 상기 절단형 원사를 포함하는 습식 은층용 폴리우레탄 합성수지 배합액으로는 특별히 제한되는 것은 아니지만, 폴리우레탄 수지에 용제, 안료, 조제 등이 포함된 것이 바람직하다. The present invention is to form a coating layer 420, as shown in Figure 4 by coating a wet silver layer polyurethane synthetic resin formulation containing the cut yarn (fiber) on the impregnated nonwoven fabric 410. Here, although it does not restrict | limit especially as a wet-type polyurethane synthetic resin compound liquid containing the cut | disconnected yarn, It is preferable that a polyurethane resin contains a solvent, a pigment, a preparation, etc.

다음으로는, 인공피혁 제조장치가 상기 습식 은층용 폴리우레탄 배합액이 코팅된 부직포를 응고시키고, 잔여 배합액을 수세 및 건조시킨 후, 사포가 구비된 버핑기로 버핑(buffing)하여, 상기 절단형 원사를 돌출시킨다(S330). 상기 습식 은층용 폴리우레탄 배합액이 코팅된 코팅층(420)에는 절단형 원사가 포함되어 있고, 본 발명은 상기 코팅층(420)에 포함된 절단형 원사를 버핑공정에 의해 돌출시켜서 돌출된 절단형 원사(430)를 발현시키는 것이 특징이다. Next, the artificial leather manufacturing apparatus coagulates the nonwoven fabric coated with the wet-silver-polyurethane formulation, washes and dries the remaining formulation, and buffs it with a buffing cloth provided with sandpaper, thereby cutting Protruding the yarn (S330). The coating layer 420 coated with the polyurethane compound solution for wet silver layer includes a cut yarn, and the present invention protrudes the cut yarn included in the coating layer 420 by protruding by a buffing process. It is characterized by expressing 430.

이러한 본 발명에 의하는 경우, 종래의 일반적인 습식 버핑 인공피혁 제품의 표면에는 존재하지 않는 절단형 원사를 표면에 도출시킴으로써, 부드럽고 고급스런 터치 효과를 발현시킬 수 있는 효과가 있다. 즉, 본 발명이 구현하는 터치 효과는 종래의 인공피혁 제품과는 달리 마이크로포어 셀(micropore cell) 내부 또는 표면에 돌출된 절단형 원사를 통해 부드럽고 고급스런 표면 터치 효과를 가지게 할 수 있는 것이다. 다시 말해서, 인공피혁 제품에 있어서도, 손으로 만지면 손으로 만지는 방향대로 털(절단형 원사)이 움직이는 일명 "SUEDE LOOK SEE"효과 또는 "FLOCKING" 효과를 구현시킬 수 있다. In the case of the present invention, by bringing the cut yarn that does not exist on the surface of the conventional general wet buffing artificial leather products on the surface, there is an effect capable of expressing a soft and luxurious touch effect. In other words, unlike the conventional artificial leather products, the touch effect implemented by the present invention may have a smooth and luxurious surface touch effect through a cut yarn protruding into or inside a micropore cell. In other words, even in artificial leather products, it is possible to implement a so-called "SUEDE LOOK SEE" effect or "FLOCKING" effect in which the hair (cut yarn) moves in the direction touched by hand when touched by hand.

또한, 일반적인 SUEDE 제품 또는 FLOCKING 제품에서는 털을 인위적으로 표면에 부착시킨 것이기 때문에, 표면 효과를 구현하는 털의 표면 접착 강도가 약하지만, 본 발명은 폴리우레탄 수지의 마이크로포어 셀로부터 절단형 원사가 버핑을 통해 자연스럽게 도출된 것이기 때문에, 표면 접착 강도를 현저하게 개선시킬 수 있는 것이다. In addition, in general SUEDE products or FLOCKING products, since the hair is artificially attached to the surface, the surface adhesive strength of the hair to realize the surface effect is weak, but the present invention is a buffing yarn from a micropore cell of polyurethane resin Since it is naturally derived through, it is possible to significantly improve the surface adhesive strength.

본 발명에 있어서, 상기 코팅층(420)에 포함된 절단형 원사를 돌출시키는 방법은 여러가지가 있을 수 있지만, 사포(sand paper)가 구비된 버핑기로 상기 코팅층(420)의 상층부를 제거하는 것이 바람직하다. 더욱 자세하게는 상기 코팅층(420)에 포함된 습식 폴리우에탄 수지의 마이크로포어 셀의 일부를 제거하는 것이다. 상기 셀의 내부 및 표면에 절단형 원사가 들어있기 때문에, 그로부터 절단형 원사를 도출해 내기 위함이다. In the present invention, there may be a number of methods for protruding the cut yarn included in the coating layer 420, it is preferable to remove the upper layer of the coating layer 420 with a buffing paper (sand paper) is provided. . In more detail, a portion of the micropore cell of the wet polyethane resin included in the coating layer 420 is removed. Since the cut yarns are contained in the inside and the surface of the cell, it is to derive the cut yarns therefrom.

이로써, 도 4에 나타난 바와 같이, 상기 부직포층(410) 상면에 절단형 원사(fiber)가 포함된 습식 은층용 폴리우레탄 배합액이 코팅되어 이루어진 것으로써, 상기 절단형 원사가 버핑에 의해 돌출된 코팅층(420)이 형성되어, 본 발명에 따라 돌출된 절단형 원사(430)가 구비된 인공피혁이 제조되는 것이다.As a result, as shown in FIG. 4, the nonwoven fabric layer 410 is coated with a wet silver layer polyurethane compounding solution including a cut yarn (fiber), and the cut yarn is protruded by buffing. The coating layer 420 is formed, the artificial leather is provided with a cut yarn 430 protruding in accordance with the present invention.

이와 같은 본 발명은 부직포 상면에 형성되어 절단형 원사가 포함되어 코팅된 코팅층 자체로부터 상기 절단형 원사가 도출된 형태이다. 그렇기 때문에, 부직포를 제외하고 이러한 1층의 층 구조를 가진 인공피혁은 의류용이나 의료용 및 기타 용도도 사용되는 것이 바람직하고, 이하에서는 신발용 인공피혁에 적합한 것으로 부직포를 제외한 2층의 층 구조를 가지는 인공피혁의 실시예를 설명하기로 한다.Such the present invention is formed on the upper surface of the nonwoven fabric is a form that is cut out from the cut yarn is included from the coated coating layer itself. Therefore, except for the non-woven fabric, the artificial leather having such a single layer structure is preferably used for clothing, medical, and other uses. Hereinafter, the two-layer layer structure except for the nonwoven fabric is suitable for artificial leather for shoes. Eggplant will be described an embodiment of artificial leather.

도 5는 본 발명의 바람직한 다른 실시예에 따른 절단형 원사가 구비된 인공피혁의 제조방법을 나타내는 흐름도이고, 도 6은 도 5에 나타난 방법에 따라 제조된 인공피혁의 단면도이다. 5 is a flowchart illustrating a method of manufacturing artificial leather with a cut yarn according to another preferred embodiment of the present invention, and FIG. 6 is a cross-sectional view of an artificial leather manufactured according to the method shown in FIG. 5.

여기에 도시된 본 발명 역시 인공피혁을 제조하는 방법에 관한 것으로, 상기한 방법을 수행하기에 적합한 인공피혁 제조장치 또는 시스템에 의해 수행되는 것이 바람직하다. The present invention shown here also relates to a method of manufacturing artificial leather, and is preferably performed by an artificial leather manufacturing apparatus or system suitable for carrying out the above method.

구체적으로, 본 발명에 따른 절단형 원사가 구비된 인공피혁의 제조방법의 다른 실시예는 인공피혁 제조장치가 나일론 또는 폴리에스테르로 이루어진 부직포를 함침용 폴리우레탄 배합액으로 함침시키고, 상기 배합액을 응고시켜서 폴리우레탄으로 함침된 부직포(610)를 준비하는 단계(S510)를 거친다. 이것은 상술한 실시 예의 S310 단계와 같으므로 상세한 설명은 그것으로 갈음한다. 다만, 도 4에 나타난 함침된 부직포(410)층은 도 6의 함침된 부직포(610)층이다.Specifically, another embodiment of the manufacturing method of artificial leather provided with a cut yarn according to the present invention, the artificial leather manufacturing apparatus is impregnated with a non-woven fabric made of nylon or polyester with the impregnated polyurethane compounding solution, By coagulating to prepare a non-woven fabric 610 impregnated with polyurethane (S510). Since this is the same as step S310 of the above-described embodiment, the detailed description is replaced by it. However, the impregnated nonwoven fabric 410 layer shown in FIG. 4 is the impregnated nonwoven fabric 610 layer of FIG. 6.

다음으로, 단계(S520)은 본 발명에 따른 인공피혁 제조장치에 의해 상기 준비된 부직포 상면에 폴리우레탄 수지가 포함된 1차 습식 은층용 폴리우레탄 배합액을 코팅시키고, 단계(S530)은 상기 1차 습식 은층용 폴리우레탄 배합액이 코팅된 부직포를 응고시키고, 잔여 배합액을 수세 및 건조시키는 것이다. 이와 같이, 1차 습식 은층용 폴리우레탄 배합액을 코팅시킴으로써, 습식 은층 베이스(base)를 형성하는 것은 신발용에 적합한 인공피혁을 제조하기 위함이다. 즉, 본 발명에 따라 절단형 원사가 포함된 폴리우레탄 배합액을 부직포에 바로 코팅시키면, 상기 배합액에 포함된 폴리우레탄 수지에 의해 형성되는 마이크로포어 셀의 접착 강도가 미흡하지만, 상기와 같이 미리 중간에 1차 습식 은층용 폴리우레탄 배합액을 코팅시킨 이후에 절단형 원사가 포함된 배합액을 코팅시키면 현저히 증가된 접착 효과를 가질 수 있게 하는 것이 가능하다.Next, step (S520) is coated with a polyurethane compound solution for primary wet silver layer containing a polyurethane resin on the prepared nonwoven fabric upper surface by the artificial leather manufacturing apparatus according to the present invention, step (S530) is the primary The nonwoven fabric coated with the polyurethane compound solution for wet silver layer is coagulated, and the remaining compound solution is washed with water and dried. As such, by coating the polyurethane compound for primary wet silver layers, forming a wet silver layer base is for producing artificial leather suitable for footwear. That is, when the polyurethane blend containing the cut yarn according to the present invention is directly coated on the nonwoven fabric, the adhesive strength of the micropore cell formed by the polyurethane resin included in the blend is insufficient, but as described above. It is possible to coat the formulation containing the cleaved yarn after coating the polyurethane formulation for the primary wet silver layer in the middle to have a significantly increased adhesive effect.

이어서, 단계(S540)은 인공피혁 제조장치가 상기 수세 및 건조된 1차 습식 은층용 폴리우레탄 배합액 층이 발수기능을 가지도록 발수 배합액으로 발수공정을 진행시키는 것이다. 이것은 상기아 같이 형성된 습식 은층 베이스 위에 2차 코팅층을 형성시킴에 있어서, 상기 2차 코팅층을 형성하는 경우 발생될 수 있는 표면 기포 발생 등의 불량을 방지하기 위한 것이다. 즉, 상기와 같은 방법으로 제조된 습식 은층 베이스에 절단형 원사가 포함된 2차 습식 은층용 폴리우레탄 배합액을 코팅시키는 경우 발생할 수 있는 불량을 방지하기 위해 상기 습식 은층 베이스에 발수 기능을 부여하는 수성계 성분(예를 들어, 불소계 또는 실리콘계 성분)으로 함층 후 건조시키는 것이다. Subsequently, in step S540, the artificial leather manufacturing apparatus advances the water repellent process with the water-repellent compound so that the water-washed and dried primary wet silver layer polyurethane compound layer has a water-repellent function. This is to prevent a defect such as surface bubbles that may occur when forming the secondary coating layer in forming the secondary coating layer on the wet silver layer base formed as described above. That is, in order to prevent the defects that may occur when coating the polyurethane compound for the second wet silver layer containing the cut-type yarn in the wet silver layer base prepared by the above method to impart a water repellent function to the wet silver layer base It is made to dry after layering with an aqueous component (for example, fluorine or silicone component).

이와 같은 제조과정을 통하여, 도 6에 도시된 바와 같이, 상기 함침된 부직포(610)층 상면에 폴리우레탄 수지가 포함된 1차 습식 은층용 폴리우레탄 배합액이 코팅되고, 발수 배합액에 의해 발수 기능을 가지도록 형성된 1차 코팅층(620)이 형성되는 것이다. 나아가, 상기 발수 배합액이 남은 발수 성분은 표면 접착을 저하시킬 수 있으므로, 표면을 버핑으로 연마한 후 다음 단계를 진행하는 것이 가능하다. 또한, 상기 버핑으로 연마하는 것은 높은 접착 강도를 요구하지 않는 경우 생략될 수도 있다.Through this manufacturing process, as shown in Figure 6, the impregnated non-woven fabric 610 is coated with a polyurethane compound for the first wet silver layer containing a polyurethane resin, the water repellent formulation The primary coating layer 620 formed to have a function is formed. Furthermore, since the water-repellent component remaining in the water-repellent formulation may lower the surface adhesion, it is possible to proceed to the next step after polishing the surface by buffing. In addition, polishing with the buffing may be omitted if high adhesion strength is not required.

계속해서, 단계(S550)은 인공피혁 제조장치에 의해 상기 발수기능을 가진 1차 습식 은층용 폴리우레탄 배합액 층 상면에 절단형 원사(fiber)가 포함된 2차 습식 은층용 폴리우레탄 배합액을 코팅시키는 것이고, 단계(S560)은 인공피혁 제조장치가 상기 2차 습식 은층용 폴리우레탄 합성수지 배합액이 코팅된 부직포를 응고시키고, 잔여 배합액을 수세 및 건조시킨 후, 사포가 구비된 버핑기로 버핑하여, 상기 절단형 원사를 돌출시키는 것을 특징으로 한다. Subsequently, step (S550) is performed by the artificial leather manufacturing apparatus to the polyurethane solution for the second wet silver layer containing the cut-type yarn (fiber) on the upper surface of the polyurethane compound solution layer for the first wet silver layer having the water-repellent function In step S560, the artificial leather manufacturing apparatus coagulates the nonwoven fabric coated with the polyurethane synthetic resin formulation for the second wet silver layer, and the remaining formulation is washed with water and dried, and then buffed with sandpaper-buffer. It is characterized in that for protruding the cut yarn.

이러한 본 발명에 있어서, 상기 절단형 원사가 포함된 습식 은층용 폴리우레탄 배합액을 코팅시키고, 버핑기로 버핑하여 상기 절단형 원사를 돌출시키는 것은 상술한 바와 같다. 즉, 상기 돌출된 절단형 원사는 상기 습식 은층용 폴리우레탄 배합액의 폴리우레탄 수지가 응고되어 형성된 마이크로포어 셀의 내부 또는 표면에 결합되어 있는 것을 특징으로 할 수 있다. 다만, 상기 2차 습식 은층용 폴리우레탄 배합액은 상기한 1차 습식 은층용 폴리우레탄 배합액과 비교하여 절단형 원사가 포함되어 있다는 것을 제외하고는 같은 배합액을 사용할 수 있다. 물론, 인공피혁을 제조하는 제조자에 따라 다양한 변형이 가능함은 명백하다. In the present invention, it is as described above to coat the polyurethane compound for wet silver layer containing the cut-type yarn, buffing with a buffing to protrude the cut yarn. That is, the protruding cut yarns may be characterized in that the polyurethane resin of the wet silver layered polyurethane compound is bonded to the inside or the surface of the micropore cell formed by coagulation. However, the same compounding liquid may be used for the secondary wet silver layer polyurethane blending liquid except that the cut yarn is included as compared with the above-described primary wet silver layered polyurethane blending solution. Of course, it is obvious that various modifications are possible depending on the manufacturer of the artificial leather.

이로써, 도 6에 도시된 바와 같이, 상기 발수기능을 가진 1차 코팅층(620) 상면에 절단형 원사(fiber)가 포함된 2차 습식 은층용 폴우레탄 배합액이 코팅되어 이루어진 것으로써, 상기 절단형 원사가 버핑에 의해 돌출된 2차 코팅층(630)이 형성되어 , 본 발명에 따라 돌출된 절단형 원사(640)가 구비된 인공피혁이 제조되는 것이다. 이와 같은 본 발명은 부직포층을 제외한 2층의 층 구조를 가짐으로써, 절단형 원사가 포함된 폴리우레탄 배합액을 부직포에 바로 코팅시키는 것보다 현저히 증가된 접착 효과를 가질 수 있으므로, 신발용에 적합한 인공피혁을 제조하기에 바람직하다. As a result, as shown in FIG. 6, the polyurethane coating liquid for secondary wet silver layer containing a cut yarn is coated on the upper surface of the primary coating layer 620 having the water repellent function, thereby cutting the cut. The secondary coating layer 630 is formed by protruding the type yarn by buffing, the artificial leather is provided with a cutting type yarn 640 protruding in accordance with the present invention. The present invention has a two-layer layer structure excluding the non-woven fabric layer, it can have a significantly increased adhesive effect than directly coating a non-woven polyurethane blend containing a cutting type yarn, it is suitable for shoes It is preferable to manufacture artificial leather.

이러한 본 발명에 의하는 경우, 종래의 일반적인 습식 버핑 인공피혁 제품의 표면에는 존재하지 않는 절단형 원사를 표면에 도출시킴으로써, 부드럽고 고급스런 터치 효과를 발현시킬 수 있는 효과가 있다. 즉, 본 발명이 구현하는 터치 효과는 종래의 인공피혁 제품과는 달리 마이크로포어 셀(micropore cell) 내부 또는 표면에 돌출된 절단형 원사를 통해 부드럽고 고급스런 표면 터치 효과를 가지게 할 수 있는 것이다. 다시 말해서, 인공피혁 제품에 있어서도, 손으로 만지면 손으로 만지는 방향대로 털(절단형 원사)이 움직이는 일명 "SUEDE LOOK SEE"효과 또는 "FLOCKING" 효과를 구현시킬 수 있다. In the case of the present invention, by bringing the cut yarn that does not exist on the surface of the conventional general wet buffing artificial leather products on the surface, there is an effect capable of expressing a soft and luxurious touch effect. In other words, unlike the conventional artificial leather products, the touch effect implemented by the present invention may have a smooth and luxurious surface touch effect through a cut yarn protruding into or inside a micropore cell. In other words, even in artificial leather products, it is possible to implement a so-called "SUEDE LOOK SEE" effect or "FLOCKING" effect in which the hair (cut yarn) moves in the direction touched by hand when touched by hand.

또한, 일반적인 SUEDE 제품 또는 FLOCKING 제품에서는 털을 인위적으로 표면에 부착시킨 것이기 때문에, 표면 효과를 구현하는 털의 표면 접착 강도가 약하지만, 본 발명은 폴리우레탄 수지의 마이크로포어 셀로부터 절단형 원사가 버핑을 통해 자연스럽게 도출된 것이기 때문에, 표면 접착 강도를 현저하게 개선시킬 수 있는 것이다. In addition, in general SUEDE products or FLOCKING products, since the hair is artificially attached to the surface, the surface adhesive strength of the hair to realize the surface effect is weak, but the present invention is a buffing yarn from a micropore cell of polyurethane resin Since it is naturally derived through, it is possible to significantly improve the surface adhesive strength.
