Description

연속 공정에 의한 자동차 매트용 부직포 제조 방법{METHOD OF MANUFACTURING NON-WOVEN FABRIC FOR CAR MAT BY CONTINUOS PROCESS}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-woven fabric for automobile mat,

본 발명은, 자동차 매트용 부직포 제조 방법에 관한 것이다.The present invention relates to a method for producing a nonwoven fabric for automotive mats.

카 매트는 라인 매트(라인 카펫), 옵션 매트 및 트렁크 매트가 이용되고 있다. 라인 매트는 자동차의 생산 라인 바디에 장착되는 카펫으로서 차 실내의 요철부에 맞도록 성형되어 탑재되고 있다. 옵션 매트는 차량구입시, 영업사원들이 착장시켜주는 카매트로서 발아래의 라인매트 위에 깔아서 이용된다. 트렁크 매트는 보통 트렁크에 하부에 깔려져 스페어 타이어 위에 스페어타이어 커버로 장착된다.The car mat uses line mat (line carpet), option mat and trunk mat. The line mat is a carpet mounted on the body of a production line of an automobile and is molded so as to fit the concave-convex portion of the automobile interior. The option mat is laid on the line mat of the foot of the vehicle as a car mat to be sold by salespeople when the vehicle is purchased. The trunk mat is usually laid on the bottom of the trunk and mounted on the spare tire with a spare tire cover.

상술한 카매트는 소프트감, 볼륨감을 발현하는 벌키성, 광택, 발색성 등의 디자인성 및 내후성, 내마모성, 탄성 회복성 등의 내구성이 요구된다. 실제로 사용하고 있는 소재로는 고급차에는 나일론 BCF(Continuous Filament), 대중차 이하에는 주로 PP-BCF, 및 폴리에스테르 SF가 많이 이용되고 있다.The above-described carmats are required to have durability such as softness, lubrication that exhibits a sense of volume, luster, glossiness and colorability, and weather resistance, abrasion resistance and resilience. Nylon BCF (Continuous Filament) is mainly used for luxury cars, PP-BCF and polyester SF are mainly used for public cars and so on.

일반적으로, 상술한 자동차 매트용 부직포는 부직포를 먼저 제조하고, 제조된 부직포를 공급롤에 권취한 후 권취된 부직포를 서서히 풀면서 니들 펀칭 및 화염 열처리를 수행하게 된다. 즉, 부직포 제조 공정과 권취 공정으로 인해 생산성이 저하하고 균일한 표면 형상을 얻는 것이 용이하지 않다는 단점을 가지고 있다. Generally, the automotive nonwoven fabric is manufactured by first preparing a nonwoven fabric, winding the produced nonwoven fabric on a supply roll, and then slowly unwinding the wound nonwoven fabric to perform needle punching and flame heat treatment. That is, it has a disadvantage that it is not easy to obtain a uniform surface shape because the productivity is reduced due to the nonwoven fabric manufacturing process and the winding process.

또한, 부직포 재료별 열처리 온도 혹은 공정이 상이하여, 공정마다 니들 펀칭과 화염 열처리를 수행하기 위한 조건을 변경해야 한다는 단점이 있어 생산성 저하와 함께 제조된 부직포의 표면 균일도가 저하할 수 있다. In addition, since the heat treatment temperature or process is different for each nonwoven fabric material, there is a disadvantage that the conditions for performing needle punching and flame heat treatment for each process must be changed, so that the productivity may be lowered and the surface uniformity of the nonwoven fabric may be lowered.

관련 기술로는, 한국공개특허 제2009-0018407호(“논슬립, 흡음 및 통기성을 가진 매트용 바닥재 및 그 제조방법과, 상기 바닥재를 사용하여 제조된 매트 및 자동차 바닥용 매트”, 공개일: 2009년02월20일)이 있다.Related art is disclosed in Korean Patent Publication No. 2009-0018407 (" Mats for non-slip, sound-absorbing and breathable flooring, manufacturing method thereof, mats made using the flooring material and mats for automobile floor, February 20).

도 1은 본 발명의 일 실시 형태에 따른 연속 공정에 의한 자동차 매트용 부직포 제조 장치의 구성도이다. 도 3은 본 발명의 일 실시 형태에 따른 부직포와 비교재의 특성 평가 결과를 도시한 것이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a configuration diagram of a nonwoven fabric manufacturing apparatus for automobiles according to a continuous process according to an embodiment of the present invention. Fig. Fig. 3 shows the results of characterization of the nonwoven fabric and the comparative material according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 자동차 매트용 부직포 제조 장치는, 원료를 공급하는 원료 공급 모듈(10)과, 공급되는 원료를 카딩하여 일정 두께와 폭을 갖는 부직포 웹을 형성하는 카딩기(20)와, 제조된 부직포 웹을 니들 펀칭하는 니들 펀칭기(30)와, 니들 펀칭된 부직포 웹의 표면을 가열하여 경화시킴으로써, 자동차 매트용 부직포를 제조하는 경화 모듈(40)과, 제조된 자동차 매트용 부직포를 일정한 크기로 커팅하는 커팅기(50)를 포함할 수 있다.1, the automotive nonwoven fabric manufacturing apparatus includes a raw material supply module 10 for supplying a raw material, a carding machine 20 for forming a nonwoven web having a certain thickness and width by carding the raw materials to be supplied, , A needle punching machine (30) for needle punching the manufactured nonwoven web, a curing module (40) for producing a nonwoven fabric for automotive mat by heating and curing the surface of the needle punched nonwoven web, The cutter 50 cuts the cutter 50 to a predetermined size.

구체적으로, 원료 공급 모듈(10)은, 원료를 공급하는 장치로, 원료를 잘게 부수며, 공기에 의해 부풀리는 장치이다. 본 발명에서 사용되는 원료는 나일론 BCF(Bulked Continuous Filament), PP-BCF(폴리프로필렌 BCF), 혹은 폴리에스테르 SF(Staple fiber) 및 PET(폴리에틸렌테레프탈레이트, Polyethylene terephthalate) 중 하나 또는 적어도 2 이상의 조합으로 이루어진 합성섬유를 포함할 수 있다.Specifically, the raw material supply module 10 is a device for supplying a raw material, which breaks the raw material finely and is blown up by air. The raw material used in the present invention may be one or a combination of at least two of nylon Bulked Continuous Filament (BCF), PP-BCF (Polypropylene BCF), polyester SF (Staple fiber) and PET (polyethylene terephthalate) Lt; / RTI > fibers.

이러한 재료들을 사용하는 이유는 부직포 제조 후, 자동차 매트로 사용시, 중요한 특성인 소프트감, 볼륨감을 발현하는 벌키성, 광택, 발색성 등의 디자인성 및 내후성, 내마모성, 탄성 회복성 등의 내구성을 만족시키기 위함과 동시에 부직포 제조 양산성을 증가시키기 위함이다.The reason for using these materials is that when used as an automobile mat after manufacturing the nonwoven fabric, it is possible to satisfy the durability such as weatherability, abrasion resistance, resilience, and the like in designability such as softness, And at the same time to increase the mass productivity of the nonwoven fabric.

카딩기(20)는, 공급되는 원료를 카딩하여 일정 두께와 폭을 갖는 부직포 웹을 형성하는 장치이다.The carding machine 20 is a device for forming a nonwoven web having a certain thickness and width by carding the supplied raw material.

니들 펀칭기(30)는, 카딩기(20)에 의해 형성된 부직포 웹을 니들 펀칭하는 장치이다. 이러한 니들 펀칭기(30)는, 다수의 홈이 형성된 니들이 촘촘하게 박힌 니들 보드를 상하 왕복시킴으로써, 부직포 웹의 표면은 골과 산이 번갈아가면서 이루어질 수 있으며, 단섬유들이 서로 물리적으로 얽히어, 하나의 부직포로 제조될 수 있다. The needle punching machine (30) is a device for needle punching a nonwoven web formed by a carding machine (20). In this needle punching machine 30, the surface of the nonwoven web can be alternately formed with the bone and the mountain alternately by reciprocating the needle board having the plurality of grooved needles densely arranged, and the staple fibers are physically entangled with each other, .

상술한 니들 펀칭기(30)에 의한 니들 펀칭 공정은, 라인 스피드 2 내지 8m/min, 타밀도는 70 내지 280/cm2일 수 있다. 더욱 구체적으로는 라인 스피드는 6m/min이며, 타밀도는 200/cm2인 것이 바람직하다. 라인 스피드가 2/min 이하일 경우, 니들 펀칭 공정 속도가 너무 느려 연속공정의 이점인 양산성이 저하될 수 있으며, 8m/min 이상일 경우에는 니들 펀칭 속도가 너무 빨라져 표면 형상의 균일도가 저하할 수 있다는 단점이 있기 때문이다. 또한, 타밀도가 70/cm2 이하일 경우, 양산성 저하 문제가 있으며, 타밀도가 280/cm2 이상일 경우에는 타밀도가 너무 증가하여 공정에 무리가 갈 수 있다.The needle punching process by the above-described needle punching machine 30 may have a line speed of 2 to 8 m / min and a taming degree of 70 to 280 / cm < 2 >. More specifically, it is preferable that the line speed is 6 m / min and the tamil degree is 200 / cm 2 . When the line speed is 2 / min or less, the speed of the needle punching process is too slow, which may lower the productivity, which is an advantage of the continuous process. When the line speed is more than 8 m / min, the needle punching speed becomes too fast, This is because there are disadvantages. Also, when the tamil degree is 70 / cm < 2 > , There is a problem of mass productivity deterioration, and when the saturation degree is 280 / cm 2 or more, the saturation degree is too high and the process may become difficult.

한편, 경화 모듈(40)은, 니들 펀칭기(30)에 의해 니들 펀칭된 부직포 웹의 표면을 가열하여 경화시킴으로써, 최종적으로 자동차 매트용 부직포를 제조할 수 있다. 이러한 경화 모듈(40)은, 불꽃에 의해 직접적으로 부직포의 표면이 그을리도록 하는 직화 방식과, 열에 의해 간접적으로 부직포의 조직이 융착되도록 하는 오븐방식 등이 있을 수 있으며, 본 발명은 이들 모두 적용 가능함에 유의하여야 한다.On the other hand, the hardening module 40 can finally produce a nonwoven fabric for automobile mat by heating and curing the surface of the needle-punched nonwoven web by the needle punching machine 30. The curing module 40 may include a direct method in which the surface of the nonwoven fabric is directly drawn by the flame and an oven method in which the structure of the nonwoven fabric is indirectly fused by heat. .

본 발명의 실시 형태에 의하면, 상술한 경화 모듈(40)에 의한 경화 공정은 니들 펀칭된 부직포 웹의 표면을 히터로 예열한 후에, 160~240℃로 용융시켜 이루어질 수 있다. 구체적으로는, 용융온도는 180℃가 바람직하다. According to the embodiment of the present invention, the curing process by the curing module 40 may be performed by pre-heating the surface of the needle-punched nonwoven web with a heater, and then melting the web at 160 to 240 ° C. Concretely, the melting temperature is preferably 180 ° C.

구체적으로, 용융온도가 160℃ 이하일 경우, 표면 온도가 저하하여 부직포의 표면이 원활하게 경화할 수 없다는 단점이 있으며, 240℃ 이상일 경우, 부직포 표면에 열처리 온도가 증가하여 표면의 섬유가 열화될 수 있기 때문이다. 상술한 부직포 표면의 열처리는 내마모성 및 강성(stiffness) 향상을 위해 적용하도록 한다. Specifically, when the melting temperature is 160 ° C or lower, there is a disadvantage in that the surface temperature is lowered and the surface of the nonwoven fabric can not be cured smoothly. When the melting temperature is 240 ° C or higher, the heat treatment temperature is increased on the nonwoven fabric surface, It is because. The above-described heat treatment of the surface of the nonwoven fabric is applied to improve abrasion resistance and stiffness.

마지막으로, 커팅기(50)는 제조된 자동차 매트용 부직포를 일정한 크기로 커팅할 수 있다. 이렇게 제조된 자동차 매트용 부직포는 폴리에틸렌 코팅층과 펠트와의 3중 결합을 통해 최종적으로 자동차 매트용 재료를 제조하는데 사용될 수 있다. Finally, the cutter 50 can cut the manufactured nonwoven fabric for a car mat to a certain size. The nonwoven fabric for automobile mat manufactured as described above can be finally used for manufacturing automotive matting materials through triple bonding of a polyethylene coating layer and felt.

이하 본 발명의 실시예와 비교예를 설명한다.Hereinafter, examples and comparative examples of the present invention will be described.

본 발명의 The 실시예Example

3.5 denier, 51mm의 polyethylene terephthalate로 되는 원솜을 상법에 따라 card, crosslapper에 걸어 sheet상 web으로 한다. 해당 web 단위 면적당 중량은 600g/m2으로 web 길이는 약 50mm이었다. 웹을 단면이 삼각형인 침을 사용하여, 상기 조건에서 200/cm2 니들 펀칭하고, 공정상에서 용융온도 180℃로 용융하여 부직포를 제조하였다. 상술한 부직포 제조 공정은 본 발명을 통해 제조되는 공정으로 부직포부터 니들펀칭 그리고 용융 열처리까지 연속식으로 이루어진 공정을 통해 부직포를 제조하였다. 3.5 denier and 51 mm polyethylene terephthalate is applied to card and crosslapper according to the commercial method to make the sheet web. The weight per web unit was 600 g / m 2 and the web length was about 50 mm. The web was subjected to 200 / cm 2 needle punching under the above conditions using a needle having a triangular cross section and melted at a melting temperature of 180 캜 in the process to produce a nonwoven fabric. The above-described nonwoven fabric manufacturing process is a process manufactured through the present invention, and a nonwoven fabric is manufactured through a continuous process from nonwoven fabric to needle punching and fusion heat treatment.

비교예Comparative Example

실시예와 같은 원솜을 가지고 부직포를 먼저 제조한 후, 통상적인 부직포 제조후 권취기에 권취시킨 후 이형형상을 만들기 위한 삼각형 침을 사용하여 200/cm2 니들 펀칭 공정을 수행한 후, 용융온도 180℃로 용융하여 부직포를 제조하였다. A nonwoven fabric was first prepared with the same raw cotton as the example, and then a conventional nonwoven fabric was wound around a winding machine, and then a 200 / cm 2 needle punching process was performed using a triangular needle to make a release profile. To produce a nonwoven fabric.

본 발명의 실시예와 비교예의 양산성을 비교하기 위해 부직포 50m 양산 기준으로 양산성을 비교하였으며, 표면의 겉보기 밀도 및 내부구조의 균일도, 그리고 인장강도를 확인하여 그 결과를 아래의 [표 1] 및 도 3에 나타내었다. In order to compare the mass productivity of the examples of the present invention and the comparative example, the mass productivity of nonwoven fabrics of 50 m was compared, the apparent density of the surface, the uniformity of the internal structure, and the tensile strength were checked. And FIG. 3, respectively.

[표 1][Table 1]

Figure 112016094663931-pat00001
Figure 112016094663931-pat00001

표 1 및 도 3에서 보는 바와 같이 본 발명의 실시예에 의해 제조된 자동차 매트용 부직포의 경우, 단위면적당 중량이 적음에도 불구하고 인장강도가 상승함을 확인할 수 있다. 이러한 이유는 부직포 웹을 형성하고 연속적인 니들 펀칭에 의해 표면의 집적도가 향상하게 되기 때문에 단위 면적당 인장강도가 증가하기 때문이다. As shown in Table 1 and FIG. 3, it can be seen that the tensile strength of the nonwoven fabric for automobile mat manufactured according to the embodiment of the present invention is increased although the weight per unit area is small. This is because the tensile strength per unit area is increased because the degree of integration of the surface is improved by forming the nonwoven web and continuous needle punching.

한편, 양산성에 대해 살펴보면, 비교예의 경우, 배치타입(batch type)으로 부직포를 먼저 제조한 후, 다시 권취기에 걸어 니들펀칭 및 용융 열처리를 수행하기 때문에, 본 발명에 의해 제조되는 부직포 웹 형성부터 니들펀칭 및 용융 열처리까지 연속적으로 수행되는 연속공정에 비해 약 30% 양산성이 떨어짐을 확인할 수 있다. On the other hand, as for the mass productivity, in the comparative example, since the nonwoven fabric is first produced in the batch type, and then the needle punching and the melting heat treatment are performed again on the winding machine, It can be confirmed that the mass productivity is lowered by about 30% compared with the continuous process which is continuously performed by punching and melting heat treatment.

상술한 바와 같이, 본 발명의 일 실시 형태에 의하면, 원료를 카딩하여 일정 두께와 폭을 갖는 부직포 웹을 형성하고 니들 펀칭 및 가열 및 경화 과정을 거침으로써, 기존 부직포 제조 공정에 비해 30% 이상 생산성과 양산성이 향상되고 표면이 균일하며, 인장 강도가 향상된 부직포를 제조할 수 있다.As described above, according to one embodiment of the present invention, a raw material is carded to form a nonwoven web having a certain thickness and width, subjected to needle punching, heating and curing processes, And a nonwoven fabric having improved productivity and surface uniformity and improved tensile strength can be produced.

한편, 도 2는 본 발명의 일 실시 형태에 따른 연속 공정에 의한 자동차 매트용 부직포 제조 방법을 설명하는 흐름도이다.2 is a flowchart illustrating a method of manufacturing a nonwoven fabric for automotive mats by a continuous process according to an embodiment of the present invention.

이하, 도 1 내지 도 2를 참조하여 본 발명의 일 실시 형태에 따른 연속 공정에 의한 자동차 매트용 부직포 제조 방법을 상세하게 설명한다.Hereinafter, a method of manufacturing a nonwoven fabric for automotive mats by a continuous process according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

본 발명의 일 실시 형태에 따른 연속 공정에 의한 자동차 매트용 부직포 제조 방법은 원료 공급 모듈(10)에 의해 원료를 공급하는 단계로부터 개시될 수 있다(S201). The method for manufacturing a nonwoven fabric for automotive mats by a continuous process according to an embodiment of the present invention may be started from a step of supplying a raw material by a raw material supply module 10 (S201).

본 발명에서 사용되는 원료는 나일론 BCF(Bulked Continuous Filament), PP-BCF(폴리프로필렌 BCF), 혹은 폴리에스테르 SF(Staple fiber) 및 PET(폴리에틸렌테레프탈레이트, Polyethylene terephthalate) 중 하나 또는 적어도 2 이상의 조합으로 이루어진 합성섬유를 포함할 수 있다.The raw material used in the present invention may be one or a combination of at least two of nylon Bulked Continuous Filament (BCF), PP-BCF (Polypropylene BCF), polyester SF (Staple fiber) and PET (polyethylene terephthalate) Lt; / RTI > fibers.

이러한 재료들을 사용하는 이유는 부직포 제조 후, 자동차 매트로 사용시, 중요한 특성인 소프트감, 볼륨감을 발현하는 벌키성, 광택, 발색성 등의 디자인성 및 내후성, 내마모성, 탄성 회복성 등의 내구성을 만족시키기 위함과 동시에 부직포 제조 양산성을 증가시키기 위함이다.The reason for using these materials is that when used as an automobile mat after manufacturing the nonwoven fabric, it is possible to satisfy the durability such as weatherability, abrasion resistance, resilience, and the like in designability such as softness, And at the same time to increase the mass productivity of the nonwoven fabric.

이후, 카딩기(20)는, 원료 공급 모듈(10)로부터 공급되는 원료를 카딩하여 일정 두께와 폭을 갖는 부직포 웹을 형성할 수 있다(S202). Thereafter, the carder 20 can form a nonwoven web having a certain thickness and width by carding the raw material supplied from the raw material supply module 10 (S202).

다음, 니들 펀칭기(30)를 이용하여 부직포 웹을 니들 펀칭할 수 있다(S203).Next, the nonwoven web can be needle-punched using the needle punching machine 30 (S203).

상술한 니들 펀칭기(30)에 의한 니들 펀칭 공정은, 라인 스피드 2 내지 8m/min, 타밀도는 70 내지 280/cm2일 수 있다. 더욱 구체적으로는 라인 스피드는 6m/min이며, 타밀도는 200/cm2인 것이 바람직하다. 라인 스피드가 2/min 이하일 경우, 니들 펀칭 공정 속도가 너무 느려 연속공정의 이점인 양산성이 저하될 수 있으며, 8m/min 이상일 경우에는 니들 펀칭 속도가 너무 빨라져 표면 형상의 균일도가 저하할 수 있다는 단점이 있기 때문이다. 또한, 타밀도가 70/cm2 이하일 경우, 양산성 저하 문제가 있으며, 타밀도가 280/cm2 이상일 경우에는 타밀도가 너무 증가하여 공정에 무리가 갈 수 있다.The needle punching process by the above-described needle punching machine 30 may have a line speed of 2 to 8 m / min and a taming degree of 70 to 280 / cm < 2 >. More specifically, it is preferable that the line speed is 6 m / min and the tamil degree is 200 / cm 2 . When the line speed is 2 / min or less, the speed of the needle punching process is too slow, which may lower the productivity, which is an advantage of the continuous process. When the line speed is more than 8 m / min, the needle punching speed becomes too fast, This is because there are disadvantages. Also, when the tamil degree is 70 / cm < 2 > , There is a problem of mass productivity deterioration, and when the saturation degree is 280 / cm 2 or more, the saturation degree is too high and the process may become difficult.

마지막으로, 경화 모듈(40)을 이용하여 니들 펀칭된 부직포 웹의 표면을 가열하여 경화시킴으로써 자동차 매트용 부직포를 제조할 수 있다(S204). 제조된 자동차 매트용 부직포는 커팅기(50)에 의해 일정한 크기로 커팅될 수 있다.Lastly, the surface of the needle punched nonwoven web may be heated and cured using the curing module 40 (S204). The manufactured nonwoven fabric for automobile mat can be cut to a certain size by the cutting machine 50.

본 발명의 실시 형태에 의하면, 상술한 경화 모듈(40)에 의한 경화 공정은 니들 펀칭된 부직포 웹의 표면을 히터로 예열한 후에, 160~240℃로 용융시켜 이루어질 수 있다. 구체적으로는, 용융온도는 180℃가 바람직하다. According to the embodiment of the present invention, the curing process by the curing module 40 may be performed by pre-heating the surface of the needle-punched nonwoven web with a heater, and then melting the web at 160 to 240 ° C. Concretely, the melting temperature is preferably 180 ° C.

구체적으로, 용융온도가 160℃ 이하일 경우, 표면 온도가 저하하여 부직포의 표면이 원활하게 경화할 수 없다는 단점이 있으며, 240℃ 이상일 경우, 부직포 표면에 열처리 온도가 증가하여 표면의 섬유가 열화될 수 있기 때문이다. 상술한 부직포 표면의 열처리는 내마모성 및 강성(stiffness) 향상을 위해 적용하도록 한다. Specifically, when the melting temperature is 160 ° C or lower, there is a disadvantage in that the surface temperature is lowered and the surface of the nonwoven fabric can not be cured smoothly. When the melting temperature is 240 ° C or higher, the heat treatment temperature is increased on the nonwoven fabric surface, It is because. The above-described heat treatment of the surface of the nonwoven fabric is applied to improve abrasion resistance and stiffness.

상술한 바와 같이, 본 발명의 일 실시 형태에 의하면, 원료를 카딩하여 일정 두께와 폭을 갖는 부직포 웹을 형성하고 니들 펀칭 및 가열 및 경화 과정을 거침으로써, 기존 부직포 제조 공정에 비해 30% 이상 생산성과 양산성이 향상되고 표면이 균일하며, 인장 강도가 향상된 부직포를 제조할 수 있다.As described above, according to one embodiment of the present invention, a raw material is carded to form a nonwoven web having a certain thickness and width, subjected to needle punching, heating and curing processes, And a nonwoven fabric having improved productivity and surface uniformity and improved tensile strength can be produced.
