본 발명은 박리강도 및 촉감이 우수한 섬유상 라미네이팅 구조물 및 그의 제조방법에 관한 것이다.The present invention relates to a fibrous laminating structure excellent in peel strength and touch and a method of manufacturing the same.
지금까지 천연피혁을 사용한 방한용 코트의 소재로서는 액상 폴리우레탄 접착제를 사용하여 천연피혁과 파일 편물을 접착하여 제조된 섬유상 라미네이팅 구조물이 많이 사용되어 오고 있다. 보다 구체적으로는 상기 액상 폴리우레탄 접착제를 천연피혁 및/또는 파일 편물 전면에 도포한 후 이들을 라미네이팅 방식으로 합포(合布)하는 방법이 사용되어 왔다.Until now, as a material of the winter coat using natural leather, a fibrous laminating structure manufactured by bonding a natural leather and a pile knitted fabric using a liquid polyurethane adhesive has been used. More specifically, a method has been used in which the liquid polyurethane adhesive is applied to the entire surface of natural leather and / or pile knitted fabric and then laminated in a laminating manner.
그러나 상기 섬유상 라미네이팅 구조물은 천연피혁을 사용하기 때문에 동물학대를 반대하는 환경보호주의자들의 많은 반대를 야기시킴과 동시에, 제조원가가 비싸고 소재공급에도 한계가 있었다.However, since the fibrous laminating structure uses natural leather, it causes many objections of environmentalists who oppose animal abuse, and at the same time, the manufacturing cost is high and the material supply is limited.
이와 같은 문제를 해결하기 위해서 천연피혁 대신에 극세사로 제조된 인공피혁을 사용하여 방한용 코트 제조용 섬유상 라미네이팅 구조물을 개발하기 위한 연구가 지속적으로 추진되어 왔다.In order to solve such a problem, research has been continuously conducted to develop a fibrous laminating structure for manufacturing a winter coat using artificial leather made of microfiber instead of natural leather.
이하 본 발명에서 극세사로 제조된 인공피혁이란 단섬유인 극세사를 니들펀칭한 부직포 상에 폴리우레탄 수지를 함침한 후 버핑처리한 제품이거나 장섬유인 극세사를 제직 또는 제편한 직물 및 편물 상에 폴리우레탄 수지를 함침한 후 버핑처리한 제품을 말한다.In the present invention, the artificial leather manufactured by microfiber is a product that is impregnated with a polyurethane resin on a nonwoven fabric needle-punched microfiber, which is a short fiber, and is a buffing product, or a polyurethane on a fabric and knitted fabric of a long fiber Refers to the product buffed after impregnating the resin.
현재까지는 주로 액상 폴리우레탄 접착제를 사용하여 극세사로 제조된 인공피혁층과 파일 편물층을 라미네이팅 하는 방법이 사용되고 있다. 이와 같은 방법은 천연피혁을 사용하지 않는다는 장점이 있는 반면에, 촉감이나 박리강도(세탁 내구성)가 나쁜 문제가 있었다.Until now, a method of laminating artificial leather layers and pile knitted layers made of microfiber mainly using liquid polyurethane adhesives has been used. While this method has the advantage of not using natural leather, there is a problem that the touch or peel strength (washing durability) is bad.
구체적으로 박리강도(세탁 내구성)가 우수한 액상 폴리우레탄 접착제를 사용하는 경우에는 강도 증가로 유연성이 저하되어 촉감이 나빠지고, 촉감개선을 위해 박리강도(세탁 내구성)가 약한 액상 폴리우레탄 접착제를 사용하는 경우에는 박리강도(세탁 내구성)가 저하 되었다.Specifically, in the case of using a liquid polyurethane adhesive having excellent peel strength (washing durability), the flexibility decreases due to the increase in strength, resulting in poor touch, and a liquid polyurethane adhesive having a weak peel strength (washing durability) is used for improving the feel. In this case, peeling strength (washing durability) was lowered.
일반적으로 상기 섬유상 라미네이팅 구조물의 촉감개선을 위해 제조 공정중 수세(Washing)나 드라이 크리닝을 실시한다. 그러나 상기 방법으로 제조된 섬유상 라미네이팅 구조물은 폴리우레탄 접착제가 접착면 전면에 존재하기 때문에 파일 편물과 극세사로 제조된 인공피혁 간의 수축율 차이를 탄력적으로 제어 할 수 없다. 그 결과 촉감개선을 위헤 수세 또는 드아이 크리닝을 하는 경우 제품상에 주름이 발생하는 또 다른 문제가 야기된다.Generally, washing or dry cleaning is performed during the manufacturing process to improve the feel of the fibrous laminating structure. However, the fibrous laminating structure manufactured by the above method cannot elastically control the difference in shrinkage between the pile knitted fabric and the artificial leather made of microfiber because the polyurethane adhesive is present on the front of the adhesive surface. As a result, washing or de-eye cleaning for the improvement of the feel causes another problem of wrinkles on the product.
이와 같은 문제점들로 현재까지 방한용 코트 소재로서 천연피혁 대신 인공피혁을 사용한 섬유상 라미네이팅 구조물은 상업화 되지 못한 실정이다.Due to these problems, fiber-laminated structures using artificial leather instead of natural leather as a coat material for winter protection have not been commercialized.
본 발명은 천연피혁 대신에 극세사로 제조된 인공피혁을 사용하고, 박리강도(세탁 내구성)와 유연성이 우수함과 동시에 촉감이 소프트하여 방한용 코트 소재로 매우 적합한 섬유상 라미네이팅 구조물 및 그의 제조방법을 제공하고자 한다.The present invention is intended to provide a fibrous laminating structure and its manufacturing method which is very suitable as a winter coat material by using artificial leather made of microfiber instead of natural leather, excellent peel strength (washing durability) and flexibility and soft touch. .

The polyurethane adhesive layer (B) is located between the artificial leather layer (C), and the polyurethane adhesive layer (B) relates to a fibrous laminating structure, characterized in that the thin film form having a net (Net) structure.
또한 본 발명은 폴리우레탄 발포체의 일면을 불꽃으로 가열, 용해한 후 여기에 파일 편물을 라미네이팅하고, 파일 편물이 라미네이팅된 폴리우레탄 발포체의 나머지 일면을 불꽃으로 가열, 용해한 후 여기에 극세사로 제조된 인공피혁을 라미네이팅함을 특징으로하는 섬유상 라미네이팅 구조물의 제조방법에 관한 것이다.In addition, the present invention is heated and dissolved one side of the polyurethane foam with a flame after laminating the pile knitted fabric, and the other side of the polyurethane foam with the pile knitted laminate is heated and dissolved with a flame and artificial leather manufactured here It relates to a method for producing a fibrous laminating structure, characterized in that the laminating.
이하 본 발명을 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.
먼저 본 발명의 섬유상 라미네이팅 구조물은 도 1과 같이 파일 편물층(A), 폴리우레탄 접착층(B) 및 극세사로 제조된 인공피혁층(C)으로 구성된다. 상기 파일 편물층(A)와 극세사로 제조된 인공피혁층(C) 사이에 폴리우레탄 접착층(B)이 위치한다.First, the fibrous laminating structure of the present invention is composed of a pile knitting layer (A), a polyurethane adhesive layer (B), and an artificial leather layer (C) made of microfiber as shown in FIG. 1. Polyurethane adhesive layer (B) is located between the pile knitting layer (A) and artificial leather layer (C) made of microfiber.
본 발명은 상기 폴리우레탄 접착층(B)이 도 2와 같은 그물상(Net) 구조를 갖는 박막 형태인 것을 특징으로 한다. 여기서 그물상(Net) 구조란 폴리우레탄 접착제가 접착면 전면에 존재하거나 도트(Dot) 상태로 존재하는 것이 아니라, 도 2와 같이 기본적으로 그물 구조(1)로 접착면에 접착제가 존재함과 동시에 그물의 눈(공백부분)을 크로스(Cross) 상태로 연결하는 부분(2)에도 랜덤하게 접착제들이 존재하는 상태를 의미한다.The present invention is characterized in that the polyurethane adhesive layer (B) is in the form of a thin film having a net (Net) structure as shown in FIG. Herein, the net structure does not exist in the polyurethane adhesive on the entire surface of the adhesive surface or in the dot state, but as shown in FIG. It means a state in which adhesives are randomly present in the part 2 connecting the eye (blank part) of the net in a cross state.
이와 같이 본 발명은 접착면에 접착제들이 앞에서 설명한 그물상 구조로 존재하기 때문에 종래 접착면 전면에 접착제가 존재하는 제품에 비해 제품의 촉감과 유연성이 우수해지고, 종래 접착면 중 일부분에만 접착제들이 도트(Dot) 상태로 존재하는 제품에 비해서는 제품의 박리강도가 우수해 진다.Thus, in the present invention, since the adhesives exist on the adhesive surface in the mesh structure described above, the product has excellent touch and flexibility compared to the products in which the adhesive exists on the front surface of the conventional adhesive surface, and only a portion of the conventional adhesive surface is the dot ( The peel strength of the product is better than that of the product in the dot state.
그 결과 본 발명의 섬유상 라미네이트 구조물은 우수한 박리강도와 동시에 소프트한 촉감을 발현할 수 있다. 상기 폴리우레탄 접착층(B)의 두께는 0.01~0.1㎜ 이다.As a result, the fibrous laminate structure of the present invention can express a soft touch with excellent peel strength. The thickness of the said polyurethane adhesive layer (B) is 0.01-0.1 mm.
파일 편물층(A)을 구성하는 파일 편물은 필요에 따라 다양한 소재의 원사로 제조할 수 있다. 바람직하기로는 아크릴 원사로 제편된 편물을 사용하는 것이 좋다. 그러나 현재까지 사용되고 있는 어떤 종류의 파일 편물을 사용할 수 있다.The pile knitted fabric constituting the pile knitted layer (A) can be manufactured from yarns of various materials as necessary. It is preferable to use a knitted fabric woven with acrylic yarns. However, you can use any kind of file knitted that is currently used.
극세사로 제조된 인공피혁층(C)은 극세사 단섬유들을 니들펀칭 방법으로 제조한 부직포에 폴리우레탄을 함침한 후 버핑처리한 제품이거나, 극세사 장섬유를 제직 또는 제편한 직물 또는 편물에 폴리우레탄을 함침한 후 버핑처리한 제품을 의미한다. 본 발명에서 사용되는 극세사는 통상의 복합방사 방법에 의해 제조되며 0.1데니어 이하의 섬도를 갖는 것이 바람직 하다.The artificial leather layer (C) made of microfiber is a buffing product after impregnating polyurethane in a nonwoven fabric made of microfiber short fibers by needle punching method, or polyurethane is applied to a fabric or knitted fabric woven or knitted with microfiber long fibers. It means the product which is buffed after impregnation. The microfiber used in the present invention is prepared by a conventional composite spinning method and preferably has a fineness of 0.1 denier or less.
본 발명의 섬유상 라미네이팅 구조물은 1.0~2.0kg/인치2의 박리강도를 갖는다. 다음으로는 본 발명의 섬유상 라미네이팅 구조물을 제조하는 방법에 대해 설명한다.The fibrous laminating structure of the present invention has a peel strength of 1.0 ~ 2.0kg / inch 2 . Next, a method for producing the fibrous laminating structure of the present invention will be described.
먼저 1단계로 통상의 라미네이팅 기대에 두께가 약 1~3mm 수준이고, 비중이 15~28kg/㎥ 수준인 폴리우레탄 발포체 롤과 파일 편물 롤을 준비한 다음, 폴리우레탄 발포체를 해포하면서 불꽃으로 폴리우레탄 발포체의 일면을 폴리우레탄 발포체의 융점 이상 온도로 가열하여 폴리우레탄 발포체 두께가 ½ 수준으로 감소되도록 용해한다. 한편 파일 편물 롤에서 파일 편물을 해포하여, 용해된 폴리우레탄 발포체 상에 파일 직물을 라미네이팅 시킨 후 압착, 권취한다.First, prepare a polyurethane foam roll and a pile knitting roll having a thickness of about 1 to 3 mm and specific gravity of 15 to 28 kg / m3 in the first step, and then foaming the polyurethane foam with a flame while deflating the polyurethane foam. One side of is heated to a temperature above the melting point of the polyurethane foam and dissolved to reduce the polyurethane foam thickness to ½ level. On the other hand, the pile knitting is unsealed in the pile knitting roll, and the pile fabric is laminated on the melted polyurethane foam, followed by pressing and winding.
다음 2단계로 통상의 라미네이팅 기대에 극세사로 제조된 인공피혁 롤과 파일 편물이 라미네이팅된 폴리우레탄 발포체 롤을 준비한 다음 상기 폴리우레탄 발포체를 해포하면서 불꽃으로 파일 직물이 라미네이팅 되지 않은 상기 폴리우레탄 발포체 일면을 폴리우레탄 발포체의 융점 이상 온도로 가열하여 폴리우레탄 발포체 자체의 두께가 0.01~0.1mm가 되도록 용해한다. 한편 극세사로 제조된 인공피혁 롤에서 인공피혁을 해포하여, 용해된 상기 폴리우레탄 발포체 상에 인공피혁을 라미네이팅 시킨 후 압착, 권취하여 본 발명의 섬유상 라미네이팅 구조물을 제조한다.Next, prepare a synthetic leather roll made of microfiber and a polyurethane foam roll laminated with a pile knitted fabric in anticipation of the normal laminating step, and then decompressing the polyurethane foam and then flaming one side of the polyurethane foam in which the pile fabric is not laminated with a flame. It is heated to a temperature higher than the melting point of the polyurethane foam and dissolved so that the thickness of the polyurethane foam itself becomes 0.01 to 0.1 mm. Meanwhile, the artificial leather is encapsulated in an artificial leather roll made of microfiber, and the artificial leather is laminated on the dissolved polyurethane foam, followed by pressing and winding to prepare the fibrous laminating structure of the present invention.
1차 및 2차에 걸친 불꽃처리로 양면이 용해된 폴리우레탄 발포체 자체의 두께는 0.01~0.1mm가 되도록 한다. 두께가 0.01mm 보다 낮을 경우에는 접착제 역할을 하는 폴리우레탄 발포체 함량이 너무 낮아져 제품의 박리강도가 저하되고, 두께가 0.1mm를 초과할 경우에는 최종 제품상에 폴리우레탄 발포체 구조가 중간층으로 그대로 존재하기 대문에 외력에 의해 폴리우레탄 발포체 부분이 쉽게 박리되어 최종제품의 박리강도가 낮아지고, 폴리우레탄 접착층이 그물상 구조를 형성할 수 없기 때문에 수세 및 드라이 크리닝시 주름이 발생하고 촉감등이 저하된다.The thickness of the polyurethane foam itself dissolved on both sides by the first and second flame treatment is to be 0.01 ~ 0.1mm. If the thickness is lower than 0.01mm, the content of the polyurethane foam that acts as an adhesive is too low to reduce the peel strength of the product, and if the thickness exceeds 0.1mm, the polyurethane foam structure remains as an intermediate layer on the final product. Due to the external force, the polyurethane foam part is easily peeled off, and thus the peeling strength of the final product is lowered, and since the polyurethane adhesive layer cannot form a network structure, wrinkles occur during washing and dry cleaning, and the touch is reduced.
이하 실시예 및 비교실시예를 통해 본 발명을 더욱 구체적으로 살펴보기로 한다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
실시예 1Example 1
통상의 라미네이팅 기대에 두께가 2mm이고 비중이 23kg/㎥인 폴리우레탄 발포체 롤과 아크릴 원사로 제조된 파일 편물 롤을 준비한 다음 상기 폴리우레탄 발포체를 해포하면서 불꽃을 이용하여 상기 폴리우레탄 발포체의 일면을 용해한다.Prepare a polyurethane foam roll having a thickness of 2 mm and a specific gravity of 23 kg / m 3 and a pile knitted roll made of acrylic yarn in accordance with a conventional laminating expectancy, and then dissolving one side of the polyurethane foam by using a flame while deflating the polyurethane foam. do.
용해처리 후 폴리우레탄 발포체의 두께가 1mm가 되도록 불꽃의 온도 및 폴리우레탄 발포체의 권취속도를 조절한다.After the dissolution treatment, the temperature of the flame and the winding speed of the polyurethane foam are adjusted so that the thickness of the polyurethane foam is 1 mm.
한편 미리 준비된 파일 편물 롤에서 파일 편물을 해포하여 용해된 폴리우레탄 발포체 상에 라미네이팅 시킨 후 이들을 압착, 권취하여 폴리우레탄 발포체 상 일면에 파일 편물이 라미네이팅 적층체를 제조한다.Meanwhile, the pile knitted fabric is rolled on a previously prepared pile knitted roll and laminated on the melted polyurethane foam, followed by pressing and winding them to prepare a pile laminate on one surface on the polyurethane foam.
이와 같이 제조된 상기 적층체(폴리우레탄 발포체 상 일면에 파일 편물이 라미네이팅 된 것)의 롤과 극세사로 제조된 인공피혁 롤을 준비한 다음, 상기 적층체를 해포하면서 불꽃으로 파일 직물이 라미네이팅 되지 않은 일면을 용해한다. 이때 용해처리 후 폴리우레탄 발포체 자체의 두께가 0.01mm가 되도록 불꽃의 온도 및 적층체 권취속도를 조절한다.After preparing a roll of the laminate (pile knitted on one side of the polyurethane foam laminated) and an artificial leather roll made of microfiber, thus laminating the laminate, one side of the pile fabric not laminated with flame Dissolve. At this time, after the dissolution treatment, the temperature of the flame and the winding speed of the laminate are adjusted so that the thickness of the polyurethane foam itself is 0.01 mm.
