합포후 함침에 의한 장섬유 인공피혁의 제조방법{Producing method of filament type artificial leather through pre-bonding for polyurethane dipping}Producing method of filament type artificial leather through pre-bonding for polyurethane dipping}

본 발명은 폴리우레탄 코팅 및 감량전에 경편지 또는 환편지를 합포하여 함침하고 감량공정을 거쳐 부직포 인공피혁과 동일한 수준의 장섬유 인공피혁을 제조하는 방법에 관한 것이다. The present invention relates to a method for producing a long-fiber artificial leather of the same level as the nonwoven artificial leather by impregnating and impregnating light or circular knitted fabrics prior to polyurethane coating and weight loss.

인공피혁의 제조방법은 일반적으로 필라멘트 원사를 스테이플 원사로 만들어 이를 카딩 펀칭 등의 공정을 거쳐 일정 밀도의 부직포 웹을 만들고 여기에 폴리우레탄 수지 등을 함침시켜 부직포 웹을 단단하게 결합시키고, 이렇게 생성된 함침포를 염색하여 인공피혁을 제조하고 있다. 또 다른 방법으로는 필라멘트 원사를 그대로 사용하여 부직포 웹을 만들어 염색하는 방법도 이용하고 있다. 이렇게 제조하는 부직포 타입의 인공피혁은 그 설비의 규모가 크고, 공정이 간단하지 않으며 원하는 품질을 얻기까지 많은 시간이 소요되는 특징이 있다. 이들 부직포 타입의 인공피혁은 양면이 동일한 수준의 외관을 가지면서 후도 및 밀도를 용이하게 조절할 수 있는 특징이 있으며 이것을 장점으로 하고 있다. 이러한 외관상의 장점 및 물성에 대한 유사제품으로서 직편물을 함침한 후 완성 제품을 합포하여 사용하는 방식을 주 로 이용하고 있는데, 이는 완성된 2가지 제품을 용도 및 물성에 맞추어 제품화하기 때문에 용이한 측면이 있는 반면, 접착에 사용된 접착제로 인해 탄성 및 촉감이 나쁘고, 제품의 가격이 2배 이상 상승한다는 문제점이 있었다. In general, the method of manufacturing artificial leather is made of a filament yarn into staple yarns, and a nonwoven web of a certain density is formed through a process such as carding punching and impregnated therein with a polyurethane resin to thereby firmly bond the nonwoven web. Artificial leather is manufactured by dyeing impregnated fabrics. Another method is to use filament yarn as it is to make a nonwoven web and dye it. The non-woven type artificial leather manufactured in this way is characterized by the large scale of the equipment, the simple process, and the long time required to obtain the desired quality. These non-woven type artificial leathers have the same appearance on both sides and have the feature of easily controlling the thickness and density, which is an advantage. As a similar product with respect to appearance and physical properties, the method is mainly used by impregnating a knitted fabric and then combining the finished product. This is an easy aspect since the two finished products are commercialized according to the purpose and properties. On the other hand, due to the adhesive used in the adhesive is bad elasticity and feel, there was a problem that the price of the product more than doubled.

Provided is a method for producing long fiber artificial leather by impregnation after synthesis.

이상 본 발명을 보다 상세히 설명하기로 한다.The present invention will be described in more detail above.

본 발명의 장섬유 인공피혁의 제조방법은 경편지 또는 환편지를 먼저 합포한 후 함침공정을 거치고 샌딩, 감량 및 염색 등의 후가공 공정을 하는 것이 특징이다.The manufacturing method of the long fiber artificial leather of the present invention is characterized in that the warp knitted or circular knitted fabrics are first combined and then subjected to an impregnation process and subjected to a post-processing process such as sanding, weight loss and dyeing.

본 발명의 장섬유 인공피혁의 제조방법 중 경편지를 통해 인공피혁을 제조하는 방법은 경편지제조 → 기모 → 셋팅 → 샌딩 → 경편 이면부의 접착에 의한 합포 → 함침(응고,수세) → 셋팅 → 용출(감량) → 분산염색 또는 산성염색 → 덤블러 건조 → 완성의 단계로 이루어지며 보다 자세한 공정은 다음과 같다.In the method of manufacturing the long fiber artificial leather of the present invention, a method of manufacturing artificial leather through warp knitted paper is made by warp knitting → raising → setting → sanding → lamination by adhesion of the back side of warp knitting → impregnation (coagulation, washing) → setting → dissolution (Reduction) → Disperse Dyeing or Acid Dyeing → Dumbler Drying → Finishing More detailed process is as follows.

우선, 경편지를 제조하는 방법으로 표면사로써 감량공정을 거친 도성분의 단사섬도가 0.03∼0.3데니어인 폴리에스터계 해도사 또는 폴리에스터계 분할사와 감량공정을 거친 도성분의 단사섬도가 0.04∼0.2데니어인 나일론계 해도사 또는 나일 론계 분할사 중 어느 하나를 사용하고, 이면사로써 단사섬도 1∼3데니어인 폴리에스터계 원사 또는 나일론계 원사를 사용하여 생지 중량 200 ~ 600g/야드로 게이지를 조정하여 경편할 수 있다. First, the single yarn fineness of the island-in-the-sea component which has undergone the weight loss process as surface yarn is 0.03 to 0.3 denier by the method of producing warp knitted paper, or the single yarn fineness of the island-in-the-sea component which has undergone the weight loss process with the polyester-based split yarn. Gauge is adjusted to 200-600 g / yard of dough weight by using any one of 0.2 denier nylon island-in-the-sea yarn or nylon-based split yarn and using polyester yarn or nylon-based yarn with single yarn fineness of 1 to 3 denier as the back side yarn. It can be handy.

상기 해도사 및 분할사의 제조형태는 일반적으로 해도형(海島形), 분할형, 직접방사형등이 있으나, 본 발명에서는 가장 단사섬도가 가늘고 천연 스웨드 느낌을 주기 위해 해도형 타입의 극세사를 사용하는 것이 바람직하다. 본 발명에서의 해도사의 해성분은 알카리에 쉽게 용해될 수 있는 분자구조를 가져야 하기 때문에 일반 폴리에스터(REGULAR POLYESTER)를 개질하여 일반 폴리에스터보다 감량율이 40배 이상 빠른 성분으로 이루어지고, 도성분은 일반 폴리에스터를 사용하게 된다. 나일론을 도성분으로 사용하는 해도형 극세사도 폴리에스터 극세사와 동일하게 해성분을 사용한다. 상기 해도사를 알카리감량하게 되면 해성분이 용출되어 도성분인 일반 폴리에스터 및 나일론만 남아 단사섬도 0.03~0.3데니어인 폴리에스터 및 나일론 극세사가 얻어지게 된다.The islands of the islands and divided yarns are generally sea island-shaped, divided, direct-spun, etc., but in the present invention, it is preferable to use the island-in-the-sea type microfiber yarn in order to give the most suede fineness and natural suede feeling. desirable. Since the sea component of the island-in-the-sea yarn in the present invention should have a molecular structure that can be easily dissolved in alkali, it is made of a component that is 40 times faster than the general polyester by modifying a general polyester (REGULAR POLYESTER), Will use ordinary polyester. The island-in-the-sea microfiber using nylon as the island component uses the sea component in the same manner as the polyester microfiber. Alkali reduction of the island-in-the-sea yarn results in elution of the sea component, leaving only polyester and nylon, which are island components, to obtain polyester and nylon microfibers having a single yarn fineness of 0.03 to 0.3 denier.

이후, 상기 얻어진 경편지의 표면부를 6∼8회 기모 샤링하고 이면부를 샌딩하여 잔털을 형성시킨 후, 상기 경편지 2매를 이면부끼리 접착하여 합포하는데, 보다 바람직하기로는 기모 샤링 후 180∼190℃의 온도로 셋팅하여 함침 준비를 하고, 84인치∼126인치 사이의 생지 폭으로 편직을 하여 이를 기모 샤링하고 샌딩하여 합포 준비를 하는데, 합포의 폭은 60인치∼64인치로 하고 합포될 경편지의 이면부를 120∼240 메쉬의 샌드페이퍼로 1∼2회 샌딩하여 약간의 털이 일어나게 하는 것이 좋다. 이는 이면부끼리의 접착력을 높이고 최종 제품인 인공피혁의 버블이 생기지 않도록 하기 위함이다. 경편지의 합포는 이면부끼리 변사의 폭을 잘 맞추어 본딩기에서 합포하여야 하는데, 합포 방식은 도트접착방식(DOT BONDING)으로서 점도 8,000∼10,000cps의 폴리우레탄을 사용하여 20∼30그램/㎡ 의 도포량으로 행하여야 한다. 표면 및 이면이 동일한 원단의 경우 사용되는 폴리우레탄의 도포량이 유사한 함량을 가짐으로써 일정한 촉감 및 충진감을 갖는 인공피혁을 제조할 수 있다. 상기 도포량 보다 낮으면 합포가 잘 되지 않고 버블이 발생하며 함침시 사용된 디메칠포름아마이드(Dimethylformamide)에 녹아 접착력이 현저히 저하되며, 도포량이 높으면 최종제품인 인공피혁의 전체적인 부드러움이 사라지고 꺽임 현상이 발생할 수 있다. 이러한 방식은 디본딩(Debonding)방식에서 잠시 붙였다가 다시 박리하는 제품과는 달리 최종 제품까지 그 영향을 미칠 수 있으므로 도포량과 접착제로 사용되는 폴리우레탄의 점도는 중요한 요소가 된다. Thereafter, brushed surface portions of the obtained warp knitted fabric 6-6 times brushed and sanded the rear surface to form fine hairs, and then the two rear knitted fabrics are bonded to each other by backside bonding, more preferably 180 to 190 after brushed shearing. It is prepared by impregnation by setting at the temperature of ℃, and knitting with a dough width between 84 inches and 126 inches, brushing and sanding it to prepare the fabric, and the width of the fabric is 60 inches to 64 inches and the warp knitted paper It is good to sand the back side of the sand once or twice with 120 ~ 240 mesh sandpaper to make some hairs. This is to increase the adhesion between the back parts and to prevent the bubbles of the artificial leather, which is the final product, to occur. The fabric of the warp knitted paper should be blended in the bonding machine by matching the width of the back side with each other. The bonding method is the dot bonding method (DOT BONDING), and it is 20-30 g / m2 using polyurethane of viscosity 8,000-10,000cps. It should be done by application amount. In the case of the fabric having the same surface and the back side, the amount of the polyurethane used may have a similar content, thereby making artificial leather having a constant feel and filling. If it is lower than the coating amount, foaming does not occur well and bubbles are generated, and the adhesion strength is significantly reduced by dissolving in dimethylformamide used during impregnation.If the coating amount is high, the overall softness of the artificial leather, which is the final product, may disappear and the bending may occur. have. This method can affect the final product, unlike a product that is temporarily attached and then peeled again in the debonding method, so the coating amount and the viscosity of the polyurethane used as the adhesive are important factors.

상기 합포 후 폴리우레탄함침, 수세, 탈DMF, 건조, 샌딩, 감량, 염색하여 건조하여 본 발명의 장섬유 인공피혁을 제공할 수 있다. Polyurethane impregnation, rinsing, de-DMF, drying, sanding, weight loss, dyeing and drying after the composite can provide a long-fiber artificial leather of the present invention.

본 발명의 장섬유 인공피혁의 제조방법 중 환편지를 통해 인공피혁을 제조하는 방법은 환편생지 → 수축 → 건조 → 기모 → 셋팅 → 샌딩 → 환편 이면부의 접착에 의한 합포 → 함침 → 용출(감량) → 분산염색 또는 산성염색 → 완성의 단계로 이루어지며 보다 자세한 공정은 다음과 같다.Method of manufacturing artificial leather through circular knitted paper of the long fiber artificial leather of the present invention is circular knitting paper → shrinkage → drying → raising → setting → sanding → lamination by adhesion of the back portion of the circular knitting → impregnation → elution (loss) → Disperse dyeing or acid dyeing → Completion of the steps, the more detailed process as follows.

사용하는 원사로는 감량공정을 거친 도성분의 단사섬도가 0.03∼0.3데니어인 폴리에스터계 해도사 또는 폴리에스터계 분할사와 감량공정을 거친 도성분의 단사 섬도가 0.04∼0.2데니어인 나일론계 해도사 또는 나일론계 분할사 중 어느 하나에 비수수축율 20∼30%, 단사섬도 1∼3데니어인 고수축 폴리에스터계 필라멘트를 인터레이스하여 환편에 사용하는데 싱글 또는 인터록 조직으로 환편할 수 있다. The yarn to be used may be a polyester-based island-in-the-sea yarn having a single yarn fineness of 0.03 to 0.3 denier after weight reduction process or a nylon-based island-in-the-sea yarn having a single yarn fineness of 0.04-0.2 denier of polyester-based split yarn and a weight loss process Alternatively, a high shrink polyester filament having a non-shrinkage ratio of 20 to 30% and a single yarn fineness of 1 to 3 deniers may be interlaced on any one of the nylon-based split yarns to be used for circular knitting, and it may be circular knitting into a single or interlock structure.

환편조직을 이용한 장섬유 인공피혁의 중간물질인 환편물은 위에서 말한 폴리에스터계 또는 나일론계 극세사와 고수축 폴리에스터계 필라멘트를 인터레이스(공기교락)한 교락사를 사용한다. 상기 고수축 폴리에스터계 필라멘트는 편제직시에는 일반 원사와 동일한 물성을 보이지만 정련 및 염색공정에서 열수(熱水)를 만나면 고수축의 물성을 보이는 원사로서 20∼30%의 비수수축율을 보유한 필라멘트를 사용하는데, 일반 폴리에스터계 필라멘트에 비해 2배 이상의 비수수축율을 보이며 폴리에스터계 또는 나일론계 극세사와 공기교락됨으로써 후의 축소가공에 의하여 폴리에스터계 또는 나일론계 극세사와 수축도의 차이에 의해 자연스러운 루프를 형성하고 기모공정이 용이해지며 직물의 스웨이드효과가 양호해진다. 환편작업(CIRCULAR KNIT)은 상기 교락사를 환편하는 것으로서 생지 중량 200 ~ 400g/YD로 게이지를 조정하여 편직한다.The circular knitted fabric, which is an intermediate material of long-fiber artificial leather using circular knit tissue, uses interlaced yarns interlaced with the polyester-based or nylon-based microfiber and the highly shrinked polyester-based filament. The high shrink polyester filament has the same physical properties as the yarn when knitted, but filaments having 20 to 30% non-shrinkage are used as the yarn showing the high shrinking properties when hot water is encountered in the refining and dyeing process. It has a non-shrinkage ratio more than twice that of general polyester filament, and is air-interlocked with polyester or nylon microfiber to form natural loops due to the difference in shrinkage with polyester or nylon microfiber by post-shrink processing. And the raising process becomes easy and the suede effect of the fabric becomes good. CIRCULAR KNIT is a circular knitting of the entangled yarn, and is knitted by adjusting the gauge to a dough weight of 200 to 400 g / YD.

상기 환편의 경우 고수축사를 사용하므로, 먼저 90∼100℃에서 30∼40분간 축소를 시킨 후 건조하여 표면을 기모하여 60∼64인치로 셋팅하여 준비하는 것이 바람직한데 상기 경편의 방법과 동일하게 합포될 이면부를 샌드페이퍼로 샌딩하여 약간의 털이 일어나게 하여 접착력을 높인다. 합포는 경편에서 합포하는 방식으로 합포를 진행한다. 환편의 합포는 표면 및 이면의 외관 차이를 극복하는 것이 아니라 후도 및 밀도를 높이고자 하는 목적에서 진행한다. 이후 합포된 원단을 폴리우 레탄 함침하고, 수세 및 탈 DMF, 건조, 샌딩, 감량 및 분할, 염색 공정을 하여 장섬유 인공피혁을 제공한다. In the case of the circular knitting, high shrinkage yarns are used, which is preferably reduced by 30 to 40 minutes at 90 to 100 ° C., then dried to raise the surface and set to 60 to 64 inches. Sand paper is sanded by sand paper, and a little hair is generated to increase adhesion. Synthesis is carried out in such a manner as to be combined in warp knitting. The composite of circular knitting is intended to improve the degree of rearing and density, rather than overcoming the difference in appearance between the front and back surfaces. The fabric is then impregnated with polyurethane, washed with water and de-MFG, dried, sanded, reduced and divided, and dyed to provide long fiber artificial leather.

상기 경편지 및 환편지를 이용하는 방법에서 공통의 공정인 폴리우레탄 함침하고, 수세 및 탈 DMF, 건조, 샌딩, 감량 및 분할, 염색 공정은 다음과 같다.Polyurethane impregnation which is a common process in the method using the warp knitted and circular knitted fabrics, washing and de-DMF, drying, sanding, weight loss and splitting, dyeing process is as follows.

상기 폴리우레탄 함침에 사용되는 폴리우레탄 탄성체는 폴리우레탄 전체 대비 고형분함량이 12~18중량%인 폴리에테르계의 폴리우레탄을 사용하는 것이 좋다. 폴리우레탄 탄성체를 알카리에 약한 폴리에스터계 우레탄을 사용하면 알카리 감량시에 폴리에스터계 우레탄 또한 감량되어 외관이 저하될 수 있다. 따라서 여기에 사용되는 우레탄은 폴리에테르계의 폴리우레탄을 사용하는 것이 바람직하다. 용제로는 범용적으로 사용하고 있는 4,4'-디메틸포름아마이드를 사용한다. 폴리우레탄은 특유의 점성으로 단독으로 사용하기 곤란하므로 용제와 혼합하여 교반하게 되는데, 이때 폴리우레탄과 용제의 혼합 비율은 1:1~1:1.5로 하여 고형분 농도가 10ㅁ 3% 정도가 되도록 1시간 정도 충분히 교반시켜 사용하고 탈포공정을 실시하여 공기방울을 제거하여야 완제품상의 핀홀을 예방할 수 있다. 함침할 때의 폴리우레탄 충진량은 인공피혁 전체 중량 대비 15~40%인 것으로 하는데 충진량이 15% 미만인 경우에는 최종 인공피혁을 손에 쥐었을 때의 탄력감이 적고, 40% 초과인 경우에는 편직물 인공피혁 고유의 표면 효과 보다는 폴리우레탄 충진제의 느낌이 너무 강하게 발현되므로 곤란하다.      The polyurethane elastic body used for the polyurethane impregnation may be a polyether-based polyurethane having a solid content of 12 to 18% by weight relative to the entire polyurethane. If the polyurethane-based elastomer is weak in alkali-based urethane, the polyester-based urethane may also be reduced during alkali reduction, thereby deteriorating the appearance. Therefore, it is preferable to use the polyether-based polyurethane for the urethane used here. As the solvent, 4,4'-dimethylformamide, which is generally used, is used. Polyurethane is difficult to be used alone due to its unique viscosity, so it is mixed with a solvent and stirred. At this time, the mixing ratio of the polyurethane and the solvent is 1: 1 to 1: 1.5 so that the solid content concentration is 10 ㅁ 3%. It is necessary to use enough stirring for a time and perform a defoaming process to remove air bubbles to prevent pinholes on the finished product. When impregnated, the polyurethane filling amount is 15 to 40% of the total weight of artificial leather. If the filling amount is less than 15%, there is less elasticity when the final artificial leather is held in hand. It is difficult because the feeling of polyurethane filler is expressed too strongly rather than inherent surface effect.

상기 폴리우레탄 충진이 완료된 선합포된 합포지를 텐터(TENTER)에서 110~130℃에서 80~120초간 건조시키는데, 건조시 처리 속도 80초 미만에서는 충분한 세팅 효과가 발현되지 않아 중량 및 폭을 제대로 발현할 수 없고, 120초 초과에서는 과도한 건조에 따른 딱딱한 촉감 발현으로 인공피혁 고유의 효과를 발현할 수 없게 된다. 건조가 완료된 원단을 120~240번 사포를 사용하여 버핑처리하여 편직물 스웨드 표면에 부착되어 있는 폴리우레탄 충진제를 제거한다. 감량은 가성소다(수산화나트륨)를 사용하여 무게대비 1.0~2.5% 사이의 농도로 조정하고 온도는 95~100℃ 사이로 해도사의 이용성 폴리에스터 부분이 완전히 용해될 수 있도록 시간을 조절한다. 약 10분에서 20분사이가 바람직하다. 감량율이 무게대비 14~20% 감량이 될 수 이러한 작업을 마친 원단은 PU코팅 후 고온의 물속에서 감량을 실시함으로써 탈 DMF가 완벽하게 이루어진다. 이로써 탈 DMF가 완벽하지 않을 때 일어나는 표면의 거칠함, 셀(CELL) 크기증대, 딱딱한 터치(TOUCH HARD)등의 문제점을 완벽하게 제어할 수 있다. 감량이 끝난 후 텐터(TENTER)에서 110~130℃에서 80~120초간 세팅시키는데 세팅시 처리 속도는 80초 미만에서는 충분한 세팅 효과가 발현되지 않아 중량 및 폭을 제대로 발현할 수 없고, 120초 초과에서는 과도한 세팅에 따른 딱딱한 촉감 발현으로 인공피혁 고유의 효과를 발현할 수 없게 된다. 건조온도는 PU코팅 후에는 항상 위에서와 같이 110~130℃에서 80~120초간 세팅시켜야 한다. 온도 130℃ 초과시에는 우레탄이 경화되기 시작하기에 터치가 딱딱해지기 때문이다. 건조 후에는 마지막 공정인 텀블러 건조기를 통하여 원단의 잔류 수축율을 제거하여야 수축율을 3%이하로 조절할 수 있으며 원단의 상호 마찰로 인하여 터치가 상당히 부드러워진다.The polyurethane-filled pre-foamed paper was dried in a tenter (TENTER) at 110-130 ° C. for 80-120 seconds, and a sufficient setting effect was not expressed at a treatment rate of less than 80 seconds during drying to properly express weight and width. If it is more than 120 seconds, it will not be possible to express the effects of artificial leather due to the appearance of hard touch due to excessive drying. The dried fabric is buffed using sandpaper 120 ~ 240 to remove the polyurethane filler attached to the surface of the knitted suede. The weight loss is adjusted to 1.0 ~ 2.5% by weight with caustic soda (sodium hydroxide) and the temperature is adjusted to 95 ~ 100 ℃ to completely dissolve the usable polyester part of sea island. Preference is given to between about 10 and 20 minutes. The weight loss rate can be reduced by 14 ~ 20% of the weight. After finishing this work, the fabric is reduced in high temperature water after PU coating, and the DMF is completely removed. This gives you complete control over issues such as surface roughness, increased cell size, and hard touch that occur when de-DMF is not perfect. After the weight loss, it is set in the tenter at 110 ~ 130 ℃ for 80 ~ 120 seconds.When setting, the treatment speed is less than 80 seconds. Due to the hard touch of excessive setting, it is impossible to express the effects of artificial leather. Drying temperature should always be set for 80 ~ 120 seconds at 110 ~ 130 ℃ as above after PU coating. This is because the touch becomes hard when the urethane starts to cure when the temperature exceeds 130 ° C. After drying, the residual shrinkage of the fabric must be removed through the tumble dryer, which is the final process, so that the shrinkage can be controlled to 3% or less, and the touch becomes quite soft due to the mutual friction of the fabrics.

염색시 사용되는 염료는 알카리에 강한 분산염료와 우레탄에 이염(MIGRATION)이 적은 염료를 사용해야 한다. 시중에 판매되고 있는 분산염료중에는 알카리에 강한 염료가 다량 판매되고 있으므로 현장 테스트를 거쳐 이염에 강한 우수한 염료를 사용해야 할 것이다. 그 이유는 PU코팅 후 감량을 하여야 하므로 알카리 농도(가성소다 무게대비 농도 1.0~2.5%)때문에 변색되지 않아야 한다. 적용 염료 및 그 이유는 경편 제품에도 동일하게 적용된다.Dyes used in dyeing should be alkali-resistant dispersion dyes and dyes with less MIGRATION in urethane. In the disperse dyes on the market, a large number of alkali-resistant dyes are sold, so it is necessary to use a field-tested and excellent dye-resistant dye. The reason for this should be weight loss after PU coating, so it should not be discolored due to alkali concentration (concentration 1.0 ~ 2.5% by weight of caustic soda). The applied dyes and their reasons apply equally to warp knitted products.

본 발명에 의하여 선합포후 함침을 함으로써 1회함침으로 2회 함침한 제품의 효과를 발현할 수 있고, 폴리우레탄 함침량을 고르게 분산시켜 일정한 촉감 및 품질을 유지할 수 있고, 합포후 함침에 의해 합포된 이면에 일정한 폴리우레탄이 존재하여 탄성 및 촉감을 우수하게 할 수 있다. 또한 부직포 인공피혁에서 발현할 수 있는 제품의 품위를 나타낼 수 있고, 표면 및 이면의 구분이 없는 제품을 제조할 수 있었다. 선합포후 함침시 합포 부분에 폴리우레탄 수지가 존재하게 되는데, 기존의 방법에서 완제품을 합포하게 되면 접착에 사용한 접착제만 존재하는데, 선합포후 함침한 제품은 폴리우레탄 수지가 접착한 부분에 존재한다. 스폰지를 녹여서 합포하는 것과도 구별이 되며, 도트 방식(DOT BONDING)으로 완제품을 합포하는 것과도 확실하게 구분된다. 스폰지 본딩은 스폰지가 전체적으로 접착되고 열로 녹여 접착시키므로 스폰지의 흔적이 남게 되나 본 발명의 인공피혁은 이러한 흔적 없이 접착부분에 고르게 폴리우레탄 수지를 함유하고 있어 촉감 및 탄성이 우수한 제품을 제공할 수 있었다.According to the present invention, by impregnating post-foaming, the effect of the product impregnated twice with one impregnation can be expressed, and the amount of polyurethane impregnation can be uniformly dispersed to maintain a constant feel and quality, and after foaming, There is a certain polyurethane on the back surface can be excellent in elasticity and feel. In addition, it can represent the quality of the product that can be expressed in non-woven artificial leather, it was possible to manufacture a product having no distinction between the front and back. Polyurethane resin exists in the part of the fabric during impregnation after the aeration. If the finished product is incorporated in the conventional method, only the adhesive used for adhesion exists. In the post-incorporation impregnated product, the polyurethane resin is present. . It can be distinguished from melting a sponge and mixing it, and it is also clearly distinguished from mixing a finished product by dot bonding. Sponge bonding is because the sponge is bonded to the entire adhesive and melted by heat to leave a trace of the sponge remains, but the artificial leather of the present invention contained a polyurethane resin evenly in the adhesive portion without such a trace could provide a product excellent in touch and elasticity.

이하 다음의 실시예에서는 본 발명의 합포후 함침에 의한 장섬유 인공피혁을 제조하는 비한정적인 예시를 하고 있다.The following examples are given as non-limiting examples of producing long fiber artificial leather by post-foam impregnation of the present invention.

After sanding the back side of this warp knitted paper with sandpaper # 150, a little hair was generated on the back side, and the two warp knits were coated with a polyurethane adhesive having a viscosity of 8,000 CPS at the dot bonding facility. After adhering to aging for 24 hours to prepare a pre-hap paper. Polyurethane with a solid content adjusted to 15% by weight was diluted by using a polyether-based polyurethane having a solid content of 30% by weight or less of viscosity of 80,000CPS or less at a ratio of 1: 1 with 4,4'-dimethylformamide. The solution was solidified by passing it through a coagulation bath. After drying at 130 ℃ for 100 seconds, buffing it with 150 mesh sandpaper, and reducing the weight loss by adding 1.5% by weight of caustic soda at 95 ℃ for 20 minutes in a liquid reducer, and reducing the weight by 16%, and again at 100 ℃ for 100 seconds.
