Description

인열강도가 우수한 인공피혁의 제조방법Manufacturing method of artificial leather with excellent tear strength

본 발명은 극세사를 이용한 부직포 인공피혁의 제조방법에 관한 것으로, 보다 상세하게는 서로 다른 2종류의 폴리머를 복합방사하여 분할형 단면을 갖는 단섬유를 제조하고 물리적으로 분할하여 극세화함으로써, 용출방법에 의해 섬유를 극세화하는 용출 공정없이 극세화가 가능하여 섬유의 손실을 막을 수 있고, 극세화 공정이 간단할 뿐만 아니라, 특히 인열강도가 우수한 부직포 인공피혁을 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing nonwoven artificial leather using microfiber, and more specifically, to dissolving two different types of polymers to produce a single fiber having a split cross section and physically dividing it into an eluting method. The present invention relates to a method for producing a nonwoven artificial leather having excellent tearing strength as well as an easy miniaturization without the elution step of minimizing the fiber, thereby preventing the loss of the fiber, the micronization process is simple.

천연피혁과 유사한 촉감과 고급스런 특성을 갖는 인공피혁을 제조하기 위하여 해도형 복합방사에 의한 극세섬유가 널리 사용되고 있다. 대한민국 공개특허 95-8857호 및 97-43411호에 기재된 바와 같이, 인공피혁의 소재가 되는 해도형 복합섬유는 통상적으로 서로 다른 2성분으로 구성되며 방사, 연신, 권축 형성, 절단 등의 공정을 거쳐 단섬유로 제조된다. 이러한 단섬유는 카딩, 니들펀칭을 통해 부직포로 제조되며 해성분 용출, 폴리우레탄 처리 등의 공정을 거쳐 인공피혁의 형태를 갖추게 된다.Microfibers by island-in-the-sea composite spinning have been widely used to produce artificial leather having a similar feel and quality characteristics to natural leather. As described in Korean Patent Publication Nos. 95-8857 and 97-43411, the island-in-the-sea composite fiber which is a material of artificial leather is usually composed of two different components and is subjected to processes such as spinning, stretching, crimp formation, and cutting. It is made of short fibers. These short fibers are made of nonwoven fabric through carding and needle punching, and are formed into artificial leather through processes such as sea component dissolution and polyurethane treatment.

그런데, 부직포 제조후에 섬유를 극세화하기 위하여 해성분을 용출하게 되면 부직포의 인열강도가 급격하게 떨어지는 문제점이 있다. 이것은 니들펀칭 과정에서 해성분간에 형성된 교락점이 용출공정에서 없어지거나 용출에 의하여 해성분이 없어져 교락이 느슨해지기 때문이다.However, if the sea component is eluted in order to make the fiber fine after the nonwoven fabric has a problem that the tear strength of the nonwoven fabric is sharply dropped. This is because the entanglement formed in the solution during the needle punching process is lost in the elution process, or the entanglement is loosened because the sea component is lost by elution.

또한, 용출후에 발생하는 폐수는 환경오염을 유발시키는 문제점이 있을 뿐만 아니라 해성분의 용출로 인한 원료의 손실 및 제조비용이 많이 드는 단점이 있다.In addition, wastewater generated after elution has a problem of causing environmental pollution, as well as a loss of raw materials and manufacturing cost due to elution of sea components.

본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로, 2종류의 폴리머를 복합방사하여 일부 분할된 단면을 갖는 단섬유로 제조하고 부직포 제조공정에서 완전한 분할이 일어나도록 하여 용출공정없이 극세화가 가능하고, 제조공정도 단순하여 경제적이며, 인열강도가 매우 우수한 부직포 인공피혁을 제조하는 방법을 제공하는 것이다.An object of the present invention is to solve the above problems, it is possible to produce a fine fiber without the elution process by producing a single fiber having a partially divided cross-section by the composite spinning of two types of polymers and a complete division in the nonwoven fabric manufacturing process In addition, the manufacturing process is simple and economical, and provides a method for producing a non-woven artificial leather with excellent tear strength.

즉, 본 발명은 서로 다른 2종류의 폴리머를 85:15∼70:30의 혼합비로 복합방사한 후 연신, 열고정, 권축 및 절단공정을 거쳐 10∼30%의 분할도를 갖고 평균섬도 0.1∼0.3데니어인 분할형 단섬유를 제조하고, 부직포 제조공정중 카아딩공정, 니들펀칭공정, 폴리우레탄 함침 및 표면처리공정을 통하여 완전히 극세화하는 것을 특징으로 하는 인열강도가 우수한 인공피혁의 제조방법에 관한 것이다.That is, according to the present invention, the two different polymers are spun at a mixing ratio of 85:15 to 70:30, followed by stretching, heat setting, crimping, and cutting, and have a degree of division of 10 to 30%, and an average fineness of 0.1 to 30. A method of manufacturing artificial leather with excellent tear strength, which is characterized by producing 0.3-denier split short fibers and completely minimizing them through a carding process, a needle punching process, a polyurethane impregnation, and a surface treatment process. It is about.

이하, 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the drawings.

본 발명에 의한 부직포 인공피혁의 소재가 되는 섬유는 용출공정이 필수적인 해도형 복합섬유(도 1) 형태가 아닌 물리적으로 분할이 가능한 분할형 복합섬유(도 2) 형태의 단면을 갖는 단섬유로, 이때 분할형 복합섬유는 서로 다른 2성분의 폴리머로 구성되는데, 일반적으로 폴리아미드와 폴리에스테르 또는 폴리에스테르와 개질 폴리에스테르 등이 사용될 수 있으며, 특히 본 발명에서 사용된 2성분 폴리머의 경우 성분 A를 폴리에스테르, 성분 B는 폴리아미드로 하거나 성분 A는 폴리아미드, 성분 B는 폴리에스테르로 구성될 수 있다.Fiber as a material of the nonwoven artificial leather according to the present invention is a short fiber having a cross-section in the form of a split type composite fiber (FIG. 2), which is physically divided, not an island-in-the-sea composite fiber (FIG. 1) form, in which an elution process is essential. In this case, the split composite fiber is composed of different two-component polymers, and in general, polyamide and polyester or polyester and modified polyester can be used. Particularly, in the case of the two-component polymer used in the present invention, component A The polyester, component B, may be made of polyamide, or component A may be made of polyamide, component B, made of polyester.

성분 A와 성분 B는 복합비를 85:15∼70:30로 하여 방사한 후, 연신과 더불어 섬유에 권축을 부여하고 열고정, 절단공정을 거쳐 50 내지 60mm의 단섬유로 제조하는데, 이렇게 하여 얻어진 단섬유의 단면은 임의로 채취한 샘플 전체의 단면에 대하여 10∼30%가 분할되어 있고 분할후의 성분 A의 평균섬도는 0.1∼0.3 데니어이다. Components A and B are spun at a compounding ratio of 85:15 to 70:30, followed by stretching and crimping the fibers, followed by heat setting and cutting to produce 50 to 60 mm short fibers. As for the cross section of the obtained short fiber, 10-30% is divided with respect to the cross section of the whole sample arbitrarily collected, and the average fineness of the component A after division is 0.1-0.3 denier.

본 발명에 의한 복합방사에서 성분 A의 함량이 85%를 넘거나 70% 미만일 경우에는 도 2에 도시된 분할형 단면을 얻기 힘들며, 단섬유의 분할도가 10% 미만에서는 후공정에서 물리적으로 분할도를 높여야 하므로 섬유에 손상이 커지게 되며, 단섬유의 분할도가 30%를 초과하게 되면 종래 분할형 필라멘트사에서 과다한 분할로 인하여 발생하는 문제점, 즉 후가공 카딩공정에서 카드기의 침포들 사이에 분할된 극세섬유들이 끼어서 배출되지 못하여 카딩 설비에 문제를 일으킬 수 있을 뿐만 아니라 균일한 웹을 얻을수 없게되어 바람직하지 못하다.When the content of component A is greater than 85% or less than 70% in the composite spinning according to the present invention, it is difficult to obtain a divided cross section shown in FIG. 2, and when the degree of splitting of short fibers is less than 10%, physical division is performed in a post process. In order to increase the degree, the damage to the fiber becomes large, and if the splitting degree of the short fiber exceeds 30%, a problem caused by excessive splitting in the conventional split filament yarn, that is, between the saggings of the carding machine in the post-processing carding process It is not desirable that the split microfibers are caught and not discharged, which can cause problems with the carding equipment as well as the failure to obtain a uniform web.

또한, 성분 A의 섬도가 0.1 데니어 미만일 경우에는 방사 생산성이 떨어질 뿐만 아니라 카딩시 침포에 말릴 위험성이 커지고 0.3 데니어를 초과하는 경우에는 부드럽고 고급스런 촉감을 갖는 인공피혁을 얻기 힘들게 된다.In addition, when the fineness of the component A is less than 0.1 denier, not only the spinning productivity decreases, but also the risk of curling in the blister during carding increases, and when it exceeds 0.3 denier, it becomes difficult to obtain an artificial leather having a soft and luxurious touch.

이와 같이 제조된 본 발명의 단섬유는 부직포 제조공정에서 카딩, 니들펀칭의 단계를 거치면서 물리적으로 분할이 일어나기 때문에 별도의 용출공정을 추가할 필요가 없는 장점을 갖는다.The short fiber of the present invention prepared as described above has the advantage that it does not need to add a separate elution process because the physical division occurs during the carding, needle punching step in the nonwoven fabric manufacturing process.

즉, 10∼30% 분할된 단섬유는 부직포 제조공정에서 카딩하여 40∼50%의 분할도를 얻을 수 있으며, 니들펀칭 공정을 거치는 동안 80∼90% 분할되고 계속하여 부직포를 폴리우레탄에 함침 처리하고 염색공정과 버핑 등의 표면처리 공정을 거쳐 100% 분할된 극세 부직포 인공피혁을 얻을 수 있다.That is, 10-30% split short fibers can be carded in the nonwoven fabric manufacturing process to obtain 40-50% splitting degree, and 80-90% split during the needle punching process and the impregnated nonwoven fabric with polyurethane. And through the surface treatment process, such as dyeing process and buffing, it is possible to obtain a 100% fine microfibre artificial leather.

이하, 실시예를 들어 본 발명을 더욱 상세히 설명하고자 하나 본 발명이 하기 실시예에 의하여 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited by the following Examples.

The short fibers were carded and needle punched to prepare a nonwoven fabric having a weight of 200 g / m 2, and the tear strength rolls were measured. Tear strength was measured by ASTM D 624. In Table 1, MD represents the tear direction in the machine direction and CD represents the cross direction.

Short fibers in the range of -30% were prepared. The short fibers were carded and needle punched to prepare a nonwoven fabric having a weight of 200 g / m 2, and the results are shown in Table 1.

비교예 1Comparative Example 1

폴리아미드를 도성분으로 하고 공중합 폴리에스터를 해성분으로 하여 70:30의 복합비로 290℃에서 복합방사하여 도 1과 같은 해도형 단면을 갖도록 하고, 연신, 권축, 열고정, 절단하여 단섬유를 제조하였다. 이 단섬유를 카딩, 니들펀칭하여 부직포를 만든 후에 가성소다 용액으로 해성분을 감량처리하여 중량 200g/㎡의 용출지 부직포를 제조하고 그 결과를 표 1에 나타내었다.The polyamide is used as the island component, and the copolyester is used as the sea component, and the composite yarn is spun at 290 ° C. at a compound ratio of 70:30 to have the island-in-the-sea cross-section as shown in FIG. 1, and the single fiber is stretched, crimped, heat-set and cut. Prepared. The short fibers were carded and needle punched to form a nonwoven fabric, followed by weight loss treatment with a caustic soda solution to produce an elution paper nonwoven fabric having a weight of 200 g / m 2 and the results are shown in Table 1.

[표 1]TABLE 1

상기 표 1에서 나타난 바와 같이 본 발명에 의해 제조된 부직포는 해도형 복합사를 소재로 하여 용출한 부직포와 비교할 때, 해도형 복합사를 소재로 한 용출지 부직포의 경우 중량 200g/㎡ 기준일 때의 인열강도가 5㎏ 이하인데 반하여 본 발명에 의한 부직포는 중량 200g/㎡ 기준일 때 7㎏ 이상으로 탁월한 인열강도를 나타내었다.As shown in Table 1, the nonwoven fabric prepared by the present invention has a weight of 200 g / m 2 when the non-woven fabric made of the island-in-the-sea composite yarn is compared with the nonwoven fabric that is eluted with the island-in-the-sea composite yarn. While the tear strength was 5 kg or less, the nonwoven fabric according to the present invention showed excellent tear strength of 7 kg or more when the weight was 200 g / m 2.

이상에서 살펴본 바와 같이 본 발명에 의하여 제조된 인공피혁은 부직포 제조 공정에서 물리적으로 분할이 일어나서 섬유가 극세화되기 때문에 해도형 복합사에서와 같은 용출공정없이 폴리우레탄 처리를 행할 수 있을 뿐만 아니라 해도형 복합섬유를 사용한 제품보다 우수한 촉감과 미려한 외관을 갖는 인공피혁을 수득할 수 있는 장점이 있다.As described above, the artificial leather manufactured according to the present invention is not only physically divided in the nonwoven fabric manufacturing process, but the fibers are micronized, so that the polyurethane treatment can be carried out without the elution process as in the island-in-the-sea composite yarn as well as the island-in-sea type There is an advantage that can be obtained artificial leather having a superior touch and beautiful appearance than the product using a composite fiber.

이밖에도 해도형 복합섬유의 경우에는 용출 공정을 거치기 때문에 제조 비용이 상승할 뿐만 아니라 해성분을 용출하여 버리기 때문에 원료의 손실이 크고 감량 폐수로 인한 환경오염 문제, 용출 공정에 의한 품질 불균일, 오염 등의 문제점이 발생하는데 비하여 본 발명은 이와 같은 문제점을 해결할 수 있게된다.In addition, in the case of island-in-the-sea composite fiber, not only the manufacturing cost increases due to the elution process, but also the elution of the sea component results in large loss of raw materials, environmental pollution due to weight loss wastewater, quality unevenness due to the elution process, and contamination. While the problem occurs, the present invention can solve such a problem.
