도 1은 본 발명에 따라 피혁원단을 제조하는 방법을 나타낸 흐름도이다. 도 1에 도시된 바와 같이, 본 발명에 따라 피혁원단을 제조하는 방법은 피혁원단 선별단계(S100), 바이브레이션 단계(S200), 버프 가공단계(S300), 코팅단계(S400), 건조단계(S500), 커버링 단계(S600), 염색 전처리 단계(S700) 및 염색단계(S800)로 이루어진다.1 is a flow chart showing a method for manufacturing a leather fabric according to the present invention. As shown in Figure 1, the method of manufacturing the leather fabric according to the present invention is selected from the leather fabrication step (S100), the vibration step (S200), buffing step (S300), coating step (S400), drying step (S500) ), The covering step (S600), the dyeing pretreatment step (S700) and the dyeing step (S800).

이하에서는 각 단계에 따라 피혁원단을 제조하는 과정을 상세히 설명한다.Hereinafter, the process of manufacturing the leather fabric according to each step will be described in detail.

먼저 제품을 생산할 피혁원단을 선별하게 된다. 이때 피혁원단은 생산할 제품의 종류(예를 들어 핸드백, 구두, 혁대, 지갑, 자켓 등) 및 품질에 따라 다양한 선별이 가능하다.(S100)First, the leather fabrics to be produced are selected. At this time, the leather fabric can be variously selected according to the type of products to be produced (for example, handbags, shoes, belts, purses, jackets, etc.) and quality.

선별된 피혁원단의 부드러움을 배가시키고 탄성을 갖도록 하기 위해 바이브레이션 단계를 거친다. 바이브레이션 단계는 회전용기인 목재드럼에 피혁원단을 투입하고, 목재드럼을 수백 회 이상 회전시키면서 피혁원단을 전반적으로 부드럽게 한다.(S210) 회전이 완료된 피혁원단에 프레스를 이용하여 미세한 천공이 피혁원단 전면에 형성되도록 한다.(S220) 이러한 바이브레이션 단계를 진행함으로써 피혁원단은 부드럽게 가공된다.(S200)Vibration steps are carried out to double the softness of the selected leather and to make it elastic. In the vibration step, the leather fabric is put into a wooden drum, which is a rotating container, and the wood drum is rotated hundreds of times or more to soften the leather fabric overall. (S220) By proceeding with this vibration step, the leather fabric is smoothly processed. (S200)

다음 단계로 피혁원단의 표면을 부드럽게 하는 동시에 광택을 부가하기 위한 버프(Buffing) 가공을 진행한다. 버프 가공 단계를 통해 천연 피혁인 피혁원단의 기모를 최대한 짧게 하여 표면이 부드럽게 형성된다.(S300)In the next step, the surface of the leather fabric is softened, and at the same time, buffing is performed to add gloss. The surface is smoothly formed by shortening the brushing of the leather fabric, which is a natural leather, through the buffing step.

버프 가공된 피혁원단은 염료 120 ~ 170 중량부, 침투제 250 ~ 350 중량부, 물 450 ~ 550 중량부 및 오일 5 ~ 15 중량부가 혼합된 코팅용 혼합물로 표면이 코팅되면서 광택이 생성된다. 이때 염료는 피혁원단이 부드러우면서도 탄력을 갖도록한다. 즉, 피혁을 느슨하게 형성하고 있는 고리형태의 미세조직이 염료 처리를 통해 탄력성을 갖게 된다. 또한 염료는 수성이기 때문에 종래에 피혁원단을 제작할 때 고온처리 과정에서 피혁원단 내에 포함된 기름이 새어 나왔던 단점을 미연에 방지한다. 또한 탄력있는 피혁원단을 이용하여 제품을 생산하게 되면 신축성이 좋아 제품의 봉제부분이 튿어지는 것을 미연에 방지할 수 있다. 또한 침투제가 포함되어 있어 코팅 약품이 피혁 내부로 원활하게 투입될 수 있다.The buffed leather fabric is coated with a mixture of 120 to 170 parts by weight of dye, 250 to 350 parts by weight of penetrant, 450 to 550 parts by weight of water, and 5 to 15 parts by weight of oil, thereby producing gloss. In this case, the dye makes the leather fabric soft and elastic. That is, the ring-shaped microstructure that loosely forms the leather has elasticity through dye treatment. In addition, since the dye is water-based, it prevents the disadvantage that oil contained in the leather is leaked during the high temperature treatment process when manufacturing the leather. In addition, when the product is produced by using a resilient leather fabric, the elasticity of the product can be prevented before the sewn part of the product. In addition, the penetration agent is included so that the coating agent can be smoothly introduced into the leather.

본 발명에서는 염료로 SB-200(삼성화학에서 제조되는 염료 번호로 피혁이 탄성을 갖도록 하는 염료이다. 이러한 염료는 피혁제조업에서 일반적으로 사용되는 것으로 본 발명에서는 염료번호 3015 또는 3025를 사용한다.)을 사용하였으며, 피혁원단의 상태 및 사용 목적에 따라 피혁원단에 형성되는 탄성의 정도를 조절할 수 있다. 즉, 피혁원단을 이용하여 남성용 구두와 여성용 구두를 만드는 경우 여성용 구두의 피혁원단을 남성용 구두의 피혁원단보다 부드럽고 탄력적이도록 제작한다. (S400)In the present invention, the dye is SB-200 (Dye number to make the elasticity of the leather by the dye number manufactured by Samsung Chem. This dye is generally used in the leather manufacturing industry, and in the present invention, dye number 3015 or 3025 is used.) Was used, and the degree of elasticity formed in the leather fabric can be adjusted according to the state and purpose of use of the leather fabric. In other words, when making men's shoes and women's shoes using the leather fabric, the leather fabric of women's shoes is made softer and more elastic than the leather fabric of men's shoes. (S400)

코팅된 피혁원단은 적정온도를 유지하는 밀폐공간의 터널에서 건조된다. 즉, 터널내에서 피혁원단에 포함된 불순물을 제거하여 건조함으로써 피혁원단의 표면을 고르게 한다. 이때 80 ~ 85 ℃의 밀폐공간에서 10 ~ 15분간 이루어지게 되어 종래의 피혁제조공정보다 상대적으로 약한 열과 적은 시간으로 진행된다. 또한 3 ~ 4회에 걸쳐 반복 건조함으로써 피혁원단의 표면을 효과적으로 고르게 형성할 수 있다. 밀폐공간의 온도가 너무 낮으면 건조 속도가 너무 느리게 되고, 온도가 너무 높으면 피혁원단이 변형될 우려가 있다. (S500)The coated leather fabric is dried in a tunnel in a closed space that maintains the proper temperature. That is, the surface of the leather fabric is evened by removing and drying impurities contained in the leather fabric in the tunnel. At this time, it is made for 10 to 15 minutes in a sealed space of 80 ~ 85 ℃ proceeds with a relatively weak heat and less time than the conventional leather manufacturing process. In addition, by repeatedly drying 3 to 4 times, the surface of the leather fabric can be effectively formed evenly. If the temperature of the enclosed space is too low, the drying rate is too slow, and if the temperature is too high, the leather fabric may be deformed. (S500)

커버링 단계는 건조된 피혁원단의 표면에 형성된 미세한 흔적(예를 들어 천연 피혁이므로 벌레에 의한 상처 등이 있을 수 있다.)을 고르게 하여 피혁원단의 제품성을 높여주게 된다.(S610) 즉, 80 ~ 85 ℃의 터널부를 통과하면서 뜨거워진 피혁원단에 표면제를 롤러로 도포하여 자연건조한다.(S620) 피혁원단의 표면은 육안으로 검안하여 미세한 흔적이 다수 존재하면 커버링 단계를 여러 번을 진행할 수도 있다. (S600)The covering step is to improve the productability of the leather fabric by evenly fine traces formed on the surface of the dried leather fabric (for example, there may be a wound by insects, etc.) (S610). The surface of the leather fabric is naturally dried by applying a roller to the heated leather fabric while passing through the tunnel part at ~ 85 ° C. (S620) If the surface of the leather fabric is visually examined with a lot of fine traces, the covering step may be performed several times. have. (S600)

염색 전처리 단계(S700)와 염색 단계(S800)를 거치면서 피혁원단이 완성된다. Leather fabric is completed through the dyeing pretreatment step (S700) and dyeing step (S800).

염색 전처리 단계는 유색 안료 200 ~ 250 중량부, 왁스 5 ~ 15 중량부, MOH 5 ~ 15 중량부, 염료 200 ~ 250 중량부, 우레탄 바인더 50 ~ 150 중량부 및 경화제 5 ~ 10 중량부를 혼합한 염색용 혼합물을 피혁원단의 표면에 도포한다. 이때 유색 안료는 피혁원단을 염색하기 위한 다양한 색상 중 하나를 선택하여 사용하면 된다. 또한 MOH(Magnesium hydroxide : 마그네슘 하이드로사이드)는 피혁원단 표면의 광택을 배가시키고, 왁스, SB-100(삼성화학에서 제조되어 판매되는 염료번호이다), 우레탄 바인더, 부타닌 바인더는 피혁원단 조직이 탄성을 갖도록 하고, 경화제는 피혁원단 조직의 결속력을 강화한다.(S700) 즉, 종래에서 사용되던 러스터(Laster)와 물 및 컴팩트(compact)를 대신하여 본 발명에서는 MOH를 사용한다.The dyeing pretreatment step includes dyeing 200 to 250 parts by weight of colored pigment, 5 to 15 parts by weight of wax, 5 to 15 parts by weight of MOH, 200 to 250 parts by weight of dye, 50 to 150 parts by weight of urethane binder, and 5 to 10 parts by weight of a curing agent. The solvent mixture is applied to the surface of the leather fabric. In this case, the colored pigment may be used by selecting one of various colors for dyeing the leather fabric. In addition, MOH (Magnesium Hydroxide) doubles the gloss of the surface of the leather fabric, and wax, SB-100 (Dye No. manufactured and sold by Samsung Chem.), Urethane binder, and butanine binder are made of leather fabric. The hardening agent enhances the binding force of the leather fabric tissue (S700). That is, MOH is used in the present invention in place of the conventionally used luster, water, and compact.

염색용 혼합물이 도포된 피혁원단은 80 ~ 85 ℃의 온도로 형성된 챔버에서 여러 번의 롤캐스터 및 다림질(아이롱) 작업을 수행하여 피혁원단을 압착하고 주름을 핀다. 롤캐스터 작업은 적어도 2회 반복하고 다림질 작업은 한 번 수행한다. 이때 롤캐스터 작업과 다림질 작업은 피혁원단의 상태에 따라 적어도 2회 반복된다. 바람직하게는 적어도 두 번의 롤캐스터 작업이 진행된 후 한 번의 다림질 작업을 수행한다.(S810)The leather fabric coated with the dyeing mixture is subjected to several roll casters and ironing operations in a chamber formed at a temperature of 80 to 85 ° C. to squeeze and wrinkle the leather fabric. The roll caster should be repeated at least twice and the ironing should be done once. At this time, the roll caster operation and the ironing operation are repeated at least twice depending on the state of the leather fabric. Preferably, at least two roll casters are performed and one ironing operation is performed (S810).

이때 피혁원단이 건조해지는 것을 방지하기 위한 습윤작업으로 탑 바인더 작업을 수행한다. 즉, 롤캐스터 작업과 탑 바인더 작업을 적어도 2회 반복함으로써 피혁원단이 건조해지지 않고 윤기를 포함할 수 있다.(S820)At this time, the top binder is performed by a wetting operation to prevent the leather fabric from drying. That is, by repeating the roll caster operation and the top binder operation at least twice, the leather fabric may not be dried and may include gloss. (S820)

이하에서는 본 발명에 따른 바람직한 실시예를 설명한다. Hereinafter, a preferred embodiment according to the present invention will be described.

20 ~ 25 S/F(스퀘어/피트)의 천연 피혁원단을 선별하여 준비한다. 선별된 피혁원단은 바이브레이션 단계를 거치면서 미세한 천공이 형성되어 부드럽게 가공된다. 가공된 피혁원단은 버프가공을 통해 표면이 매끄럽게 형성된다. 피혁원단은 표면에 SB-200 150 ㎎, 침투제 300 ㎎, 물 500 ㎎ 및 오일 10 ㎎이 혼합된 코팅용 혼합물을 도포하여 피혁원단이 탄성 및 광택을 갖도록 한다. 이때 피혁원단은 80 ℃의 온도에서 15분간 건조된다. 이러한 건조는 4회를 반복하여 실행되어 피혁원단이 완전하게 건조되도록 한다.Select and prepare 20 ~ 25 S / F (square / feet) of natural leather. Selected leather fabrics are processed through a vibrating step to form fine perforations and are processed smoothly. The processed leather fabric has a smooth surface through buffing. The leather fabric is coated with a coating mixture containing 150 mg of SB-200, 300 mg of penetrant, 500 mg of water and 10 mg of oil on the surface to make the leather fabric elastic and glossy. At this time, the leather fabric is dried for 15 minutes at a temperature of 80 ℃. This drying is repeated four times to allow the leather to dry completely.

건조된 피혁원단은 표면을 육안으로 검사하여 미세한 흔적의 정도에 따라 표면제를 여러 번 도포하여 피혁원단을 커버링한다. 다음으로 피혁원단을 염색하고자하는 색상을 선택하고 이에 맞는 유색 안료가 포함된 염색용 혼합물을 제조하여 피혁원단을 염색한다. 즉, 유색 안료 220 ㎎, 왁스 10 ㎎, MOH 10㎎, SB-100 220㎎, 우레탄 바인더 100 ㎎ 및 부타닌 바인더 100 ㎎가 혼합된 염색용 혼합물을 제조한다. 이때 피혁원단의 조직 결속을 강화시키기 위해 7 ㎎의 경화제를 혼합한다. 염색된 피혁원단은 롤캐스터 및 다림질 작업을 통해 압착되고 탑 바인더 작업을 통해 피혁원단의 건조함을 방지하여 제품을 생산하기에 적합한 부드럽고 탄성있는 피혁을 형성한다. 바람직하게는 롤캐스터 작업 2회 및 다림질 작업 1회를 적어도 2회 수행한다. The dried leather fabric is visually inspected on the surface to cover the leather fabric by applying the surface agent several times according to the degree of fine traces. Next, select the color to be dyed leather fabric, and prepare a dyeing mixture containing a color pigment according to the dyeing leather fabric. That is, a dyeing mixture was prepared in which 220 mg of colored pigment, 10 mg of wax, 10 mg of MOH, 220 mg of SB-100, 100 mg of urethane binder, and 100 mg of butanine binder were mixed. At this time, 7 mg of hardener is mixed to strengthen the tissue binding of the leather fabric. The dyed leather fabric is pressed through roll casters and ironing operations, and the top binder operation prevents the drying of the leather fabric to form a soft and elastic leather suitable for producing a product. Preferably at least two roll caster operations and one ironing operation are performed.

본 발명에 의해 제조된 피혁원단은 부드럽고 탄성이 좋아 피부에 직접적으로 접촉되는 물건들(예를 들어 핸드폰 케이스와 같이 피부에 닿는 물건)을 제조하는데 사용이 가능하다.The leather fabric produced by the present invention is soft and elastic and can be used to make things that are in direct contact with the skin (for example, things that touch the skin, such as a cell phone case).

도 1은 본 발명에 따라 피혁원단을 제조하는 방법을 나타낸 흐름도.1 is a flow chart showing a method of manufacturing a leather fabric according to the present invention.
