Description

온실용 보온 커버 및 그 제조 방법{COVER FOR KEEPING WARM FOR GREEN HOUSE AND METHOD MANUFACTURING THE SAME}Insulating cover for greenhouse and method of manufacturing the same {COVER FOR KEEPING WARM FOR GREEN HOUSE AND METHOD MANUFACTURING THE SAME}

본 개시 내용은 비닐 하우스 등 온실에 사용되는 보온 커버 및 그 제조 방법에 관한 것이다.The present disclosure relates to a thermal insulation cover used in greenhouses such as greenhouses and a method of manufacturing the same.

일반적으로, 비닐하우스 등의 온실은 외부 기온의 영향을 받지 않고 내부의 온도를 유지하여 작물 등을 재배하기 위해 사용된다.Generally, greenhouses such as greenhouses are used to grow crops by maintaining the internal temperature without being affected by external temperature.

비닐하우스는 예를 들어 금속 재질의 프레임에 비닐재질의 시트를 씌워 내부 공간을 형성한 구조로 되어 있다. 비닐하우스는 내부 온도를 적정 수준으로 유지 관리할 수 있도록, 외부에 보온용 커버가 설치된다. 예를 들어, 비닐하우스 내부 온도가 높거나 햇빛이 필요한 경우에는 커버를 개방시키고, 외부 기온이 낮은 경우에는 비닐하우스 외부에 커버를 덮어 열기가 빠져나가는 것을 방지할 수 있다.For example, a greenhouse is structured by covering a metal frame with vinyl sheets to form an internal space. In order to maintain the internal temperature at an appropriate level, a greenhouse is installed with a thermal cover on the outside. For example, if the temperature inside the greenhouse is high or sunlight is needed, the cover can be opened, and if the outside temperature is low, the cover can be placed on the outside of the greenhouse to prevent heat from escaping.

보온용 커버는 솜과 부직포를 포함하는 보온재와 보온재의 양면에 배치되는 외피가 결합된 구조로 되어 있다. 보온재의 양면에 외피가 적층되어 니들 펀칭으로 결합된다. 그런데, 상기한 종래의 커버는 개폐가 반복되면서 니들 펀칭 부분이 쉽게 뜯어지는 불량이 발생되는 문제가 있다.The thermal cover has a structure that combines an insulating material containing cotton and non-woven fabric and an outer shell disposed on both sides of the insulating material. The outer skin is laminated on both sides of the insulation material and joined by needle punching. However, the above-described conventional cover has a problem in that the needle-punched portion is easily torn off as the cover is repeatedly opened and closed.

커버의 보온재와 외피를 전체적으로 고주파 접합하는 구조의 경우 결합력은 높일 수 있으나, 내부의 습기가 외부로 빠져나가지 못하고 고여 한 곳으로 몰리면서 커버가 터지는 현상이 빈번하게 발생된다.In the case of a structure in which the cover's insulating material and the outer skin are joined together at a high frequency, the bonding strength can be increased, but the phenomenon of the cover bursting frequently occurs as the moisture inside is unable to escape to the outside and is concentrated in one place.

본 과제는 고주파 접합을 통해 보다 견고하게 접합되면서도 내부 습기가 부직포를 통과하여 보다 쉽게 배출될 수 있도록 된 온실용 보온 커버 및 그 제조 방법을 제공하는 것이다.This project is to provide a thermal insulation cover for a greenhouse that is more firmly joined through high-frequency bonding, while allowing internal moisture to pass through the non-woven fabric and be discharged more easily, and a method of manufacturing the same.

본 과제는 니들 펀칭을 통해 내부 습기의 배출 효과를 높이면서도 커버의 접합 강도를 높일 수 있도록 된 온실용 보온 커버 및 그 제조 방법을 제공하는 것이다.This project is to provide a thermal insulation cover for a greenhouse and a manufacturing method thereof that can increase the joint strength of the cover while increasing the effect of discharging internal moisture through needle punching.

본 구현예의 보온 커버는, 내부에 마련되는 보온재와, 상기 보온재의 양면에 각각 적층되어 표면을 이루는 외피를 포함할 수 있다.The thermal insulation cover of this embodiment may include a thermal insulation material provided inside, and an outer shell that is laminated on both sides of the insulation material to form a surface.

상기 보온재는 솜층과 솜층의 양면에 적층되는 내피를 포함할 수 있다.The thermal insulation material may include a cotton layer and an inner layer laminated on both sides of the cotton layer.

상기 내피는 부직포, 비닐을 포함한 합성수지, PE폼을 포함하는 발포시트에서 선택되는 적어도 하나일 수 있다. The inner skin may be at least one selected from foam sheets including non-woven fabric, synthetic resin including vinyl, and PE foam.

상기 외피는 천, 알루미늄 반사 시트에서 선택되는 적어도 하나일 수 있다.The outer shell may be at least one selected from cloth and aluminum reflective sheet.

상기 보온 커버는 일정 간격을 따라 접합부가 형성되며, 상기 접합부는 상기 솜층과 내피를 접합한 니들펀칭부와, 상기 니들펀칭부의 일부에서 보온재와 상기 외피를 열 접합한 융착부를 포함할 수 있다.The thermal cover has joints formed at regular intervals, and the joints may include a needle-punched portion that joins the cotton layer and the inner shell, and a fusion portion that heat-bonds the insulation and the outer shell in a portion of the needle-punched portion.

상기 융착부는 고주파 접합으로 형성될 수 있다.The fused portion may be formed through high-frequency bonding.

상기 융착부의 폭은 상기 니들펀칭부 폭의 30 내지 70% 크기로 형성될 수 있다.The width of the fusion portion may be 30 to 70% of the width of the needle punching portion.

상기 융착부는 상기 니들펀칭부의 중심부에 형성될 수 있다.The fusion portion may be formed at the center of the needle punching portion.

본 구현예의 보온 커버 제조 방법은 솜층과 내피 및 외피를 준비하는 단계, 솜층의 외측에 내피를 적층하여 보온재를 형성하는 단계, 보온재를 따라 일정 간격으로 솜층과 내피를 접합하는 1차 접합 단계, 보온재 외측에 외피를 적층하는 단계, 외피를 따라 일정 간격으로 보온재와 외피를 접합하는 2차 접합 단계를 포함할 수 있다.The method of manufacturing an insulating cover of this embodiment includes preparing a cotton layer, an inner layer, and an outer layer, forming an insulating material by laminating the inner layer on the outside of the cotton layer, a first bonding step of joining the cotton layer and the inner layer at regular intervals along the insulating material, and an insulating material. It may include a step of laminating the outer skin, and a secondary bonding step of joining the insulation material and the outer skin at regular intervals along the outer skin.

상기 1차 접합 단계는, 상기 솜층과 내피를 니들 펀칭하여 접합하는 니들펀칭 접합단계를 포함할 수 있다.The first bonding step may include a needle punching bonding step of bonding the cotton layer and the endothelium by needle punching.

상기 2차 접합 단계는, 니들펀칭 접합 영역의 일부에 상기 외피와 보온재를 열 접합하는 융착 접합단계를 포함할 수 있다.The secondary bonding step may include a fusion bonding step of thermally bonding the outer shell and the insulation material to a portion of the needle punching bonding area.

상기 융착 접합 단계에서, 융착 접합 영역은 상기 니들펀칭 접합 영역의 중심부에 형성될 수 있다.In the fusion bonding step, a fusion bonding region may be formed in the center of the needle punching bonding region.

상기 융착 접합 영역의 폭은 상기 니들펀칭 접합 영역 폭의 30 내지 70% 크기로 형성될 수 있다. The width of the fusion bonded region may be 30 to 70% of the width of the needle punched bonded region.

이와 같이 본 구현예에 의하면, 니들 펀칭과 열 융착에 의한 복합적인 접합 구조로, 두 접합 방식의 장정을 얻을 수 있다.According to this embodiment, it is possible to obtain a binding using two bonding methods through a complex bonding structure using needle punching and heat fusion.

이에, 보다 견고하게 접합되면서도 내부 습기를 보다 쉽게 배출될 수 있게 된다. 따라서, 장시간 동안 반복적인 사용시에도 커버가 뜯어져 분리되는 것을 방지하고, 내부에 고인 습기가 배출되지 못해 한 곳으로 쏠려 커버가 터지는 것을 방지할 수 있다.Accordingly, while being more firmly joined, internal moisture can be discharged more easily. Therefore, it is possible to prevent the cover from being torn and separated even when used repeatedly for a long period of time, and to prevent the moisture accumulated inside from being discharged and concentrated in one place, thereby preventing the cover from bursting.

The cotton layer 21 may be a sheet structure formed of single fibers to a predetermined thickness. The thickness of the cotton layer 21 can be varied in various ways. The inner skin 22 can be laminated on both sides of the cotton layer 21 to form one body.

본 실시예에서, 내피(22)는 부직포로 이루어질 수 있다. 부직포는 단섬유 또는 장섬유를 열처리로 접합한 얇은 시트 구조물일 수 있다. 상기한 구조 외에 내피는 비닐을 포함한 합성수지나 PE폼을 포함하는 발포시트 등으로 이루어질 수 있다.In this embodiment, the inner skin 22 may be made of non-woven fabric. Nonwoven fabric may be a thin sheet structure made by joining short fibers or long fibers through heat treatment. In addition to the above structure, the inner shell may be made of synthetic resin containing vinyl or foam sheet containing PE foam.

내피(22)는 솜층(21)을 양면에서 감싸 보호하며 솜층(21)의 형태를 안정적으로 유지시킨다.The inner skin (22) protects the cotton layer (21) by covering it on both sides and stably maintains the shape of the cotton layer (21).

외피(30)는 보온재(20)의 부직포(22) 외측에 적층되어 보온 커버(10)의 가장 외측면을 이룬다. 외피(30)는 강성의 재질로 내부 보온재(20)를 보호하며, 전체적으로 커버(10)의 내구성을 높인다. The outer shell 30 is laminated on the outside of the nonwoven fabric 22 of the thermal insulation material 20 and forms the outermost surface of the thermal insulation cover 10. The outer shell 30 is made of a rigid material and protects the internal insulation material 20, thereby increasing the overall durability of the cover 10.

본 실시예에서, 외피(30)는 천 재질로 이루어질 수 있다. 외피는 천 이외에 알루미늄 반사 필름 구조의 원사로 직조된 시트와 같이 빛을 반사할 수 있도록 된 시트로 이루어질 수 있다. 보온재(20)의 양면에 적층되는 외피(30)는 커버 내외측에 대해 모두 동일한 재질로 이루어질 수 있다. 상기한 구조 외에, 커버의 외측에 위치하는 외피와 반대쪽인 내측에 위치하는 외피가 각각 상이한 재질로 이루어질 수 있다. 예를 들어, 커버 내측에 위치하는 외피는 방수 재질의 시트로 이루어질 수 있다. 외피(30)는 직조된 구조로 표면의 수많은 틈새를 통해 내부 습기나 물이 외부로 배출될 수 있다.In this embodiment, the outer shell 30 may be made of a cloth material. In addition to fabric, the outer shell may be made of a sheet capable of reflecting light, such as a sheet woven from yarn with an aluminum reflective film structure. The outer shell 30 laminated on both sides of the insulation material 20 may be made of the same material for both the inside and outside of the cover. In addition to the above structure, the outer shell located on the outside of the cover and the outer shell located on the opposite inner side may be made of different materials. For example, the outer shell located inside the cover may be made of a sheet of waterproof material. The outer shell 30 has a woven structure, and internal moisture or water can be discharged to the outside through numerous gaps in the surface.

보온 커버(10)는 가장 안쪽에 솜층(21)이 배치되고 솜층(21)의 외측에 내피(22)와 외피(30)가 차례로 적층되고, 접합부(40)에 의해 접합되어 한 몸체를 이룬다.The thermal cover 10 has a cotton layer 21 disposed on the innermost side, and an inner skin 22 and an outer skin 30 are sequentially stacked on the outside of the cotton layer 21, and are joined by a joint 40 to form one body.

도 1에 도시된 바와 같이, 접합부(40)는 보온 커버(10)의 폭 방향을 따라 일정 간격으로 형성된다. 접합부(40)는 커버(10)를 접합한 영역을 의미할 수 있다. 각 접합부(40)는 동일한 구조를 이루며, 길이 방향을 따라 연속적으로 형성될 수 있다.As shown in FIG. 1, the joint portions 40 are formed at regular intervals along the width direction of the thermal insulation cover 10. The joint portion 40 may refer to an area where the cover 10 is joined. Each joint 40 has the same structure and can be formed continuously along the longitudinal direction.

접합부(40)와 접합부(40) 사이 영역은 솜층(21)에 의해 부풀려 내부 공기를 머금을 수 있는 공기층부(50)를 이룬다. The area between the joint portion 40 and the joint portion 40 is inflated by the cotton layer 21 to form an air layer portion 50 that can contain internal air.

본 실시예에서, 접합부(40)는 솜층(21)과 내피(22)를 니들 펀칭하여 접합한 니들핀칭부(42)와, 니들핀칭부(42) 영역의 일부에서 외피(30)와 보온재(20)를 열 접합한 융착부(44)를 포함할 수 있다.In this embodiment, the joint portion 40 is a needle pinching portion 42 where the cotton layer 21 and the inner shell 22 are joined by needle punching, and the outer shell 30 and the insulation material ( It may include a fusion portion 44 obtained by thermally bonding 20).

이와 같이, 커버(10)를 접합함에 있어서, 접합부(40)가 니들 펀칭을 통한 접합과 열 융착에 의한 접합의 복합적 접합 구조로 형성됨에 따라, 솜층(21)이 머금고 있는 습기를 쉽게 외부로 배출하면서도 접합부(40)가 쉽게 뜯어져 분리되는 것을 최소화할 수 있게 된다.In this way, when joining the cover 10, the joint portion 40 is formed as a complex joint structure of jointing through needle punching and jointing by heat fusion, so that the moisture contained in the cotton layer 21 can be easily released to the outside. It is possible to minimize the joint portion 40 from being easily torn and separated during discharge.

니들핀칭부(42)는 니들 펀칭(needle punching) 공정에 의해 접합된 영역을 의미할 수 있다. 니들 펀칭은 서로 겹쳐진 시트에 대해 예를 들어 수직방향으로 니들이 복수회 반복적으로 관통되면서 섬유웹을 상호 결합하는 것으로, 그 결합 구조나 작용에 대해서는 이미 알려져 있어 이하 상세한 설명은 생략한다.The needle pinching portion 42 may refer to an area joined by a needle punching process. Needle punching is a method of bonding fiber webs to each other by repeatedly penetrating overlapping sheets in a vertical direction with a needle, for example, multiple times. The bonding structure and action are already known, so a detailed description below will be omitted.

니들핀칭부(42)는 니들 펀칭에 의해 솜층(21)과 내피(22)의 섬유웹이 서로 엉키면서 상호 결합된다. 이에, 솜층(21)의 습기나 물이 니들 펀칭에 의해 내피(22)에 형성된 무수한 홀을 통해 쉽게 내피(22) 외측으로 배출될 수 있다. 이렇게 내피(22) 외부로 배출된 습기나 물은 외피(30)를 통과하여 커버(10) 밖으로 배출된다. 따라서, 솜층(21)의 습기가 내피(22)에서 배출되지 못하고 뭉쳐져 결국 터지는 현상을 효과적으로 방지할 수 있다.In the needle pinching portion 42, the fiber webs of the cotton layer 21 and the inner skin 22 are entangled and coupled to each other by needle punching. Accordingly, moisture or water in the cotton layer 21 can be easily discharged to the outside of the inner skin 22 through the numerous holes formed in the inner skin 22 by needle punching. Moisture or water discharged to the outside of the inner shell 22 passes through the outer shell 30 and is discharged out of the cover 10. Therefore, it is possible to effectively prevent the phenomenon in which moisture in the cotton layer 21 cannot be discharged from the inner skin 22 and clumps up and eventually bursts.

융착부(44)는 열 융착에 의한 접합 공정을 통해 접합된 영역을 의미할 수 있다. 열 융착이란 두 시트의 표면을 열과 압력을 가해 접합하는 것으로, 그 결합 구조와 작용에 대해서는 이미 알려져 있어 이하 상세한 설명은 생략한다.The fused portion 44 may refer to an area joined through a joining process using heat fusion. Heat fusion is a process of joining the surfaces of two sheets by applying heat and pressure, and the bonding structure and function are already known, so detailed descriptions are omitted below.

융착부(44)는 열 융착에 의해 솜층(21)과 내피를 포함한 보온재(20) 및 외피(30)를 서로 열과 압력으로 접합되면서 상호 결합된다.The fusion portion 44 is bonded to the cotton layer 21, the insulation material 20 including the inner skin, and the outer skin 30 by heat and pressure.

이와 같이, 본 실시예의 커버(10)는, 니들 펀칭과 열 융착을 이용한 복합적인 접합 구조로, 내부 습기를 효과적으로 제거하면서 접합 강도를 높일 수 있게 된다.In this way, the cover 10 of this embodiment has a complex bonding structure using needle punching and heat fusion, and can effectively remove internal moisture and increase bonding strength.

즉, 본 실시예의 접합부(40)는 열접합에 의한 융착부(44)를 구비하여, 솜층(21)과 내피(22) 및 외피(30)는 보다 견고하게 접합되어 반복적인 사용시에도 솜층(21)과 내피(22) 및 외피(30)가 서로 쉽게 분리되는 것을 방지할 수 있다. That is, the joint portion 40 of the present embodiment is provided with a fusion portion 44 by heat bonding, so that the cotton layer 21, the inner skin 22, and the outer skin 30 are more firmly joined, so that the cotton layer 21 remains intact even during repeated use. ) and the inner skin 22 and the outer skin 30 can be prevented from being easily separated from each other.

또한, 언급한 바와 같이 접합부(40)는 니들핀칭부(42)를 구비함으로써, 솜층(21)에 머금은 습기가 니들 펀칭의 형성된 미세한 구멍을 통해 용이하게 외부로 배출될 수 있다.In addition, as mentioned, the joint portion 40 is provided with the needle pinching portion 42, so that moisture contained in the cotton layer 21 can be easily discharged to the outside through the fine holes formed by needle punching.

종래 열 융착에 의해 접합된 커버의 경우, 커부 내부의 습기가 부직포 등의 내피를 통과하여 빠져나가지 못해 내부에서 뭉쳐져 한쪽으로 쏠리면서 커버가 터지는 문제가 발생된다. 또한, 니들 펀칭에 의해 접합된 커버의 경우 그 접합력이 약해 반복적인 사용시 접합 부위가 뜯어지면서 커버의 형태가 쉽게 변형된다. 비닐하우스 등의 온실에 설치되는 커버는 온실 개폐를 위해 반복적으로 말거나 펼치게 되는 데, 이러한 반복적인 작업에 의해 쉽게 접합부가 뜯어지게 된다.In the case of a cover joined by conventional heat fusion, the moisture inside the cover cannot escape through the inner layer of the non-woven fabric, etc., causing it to clump up inside and slant to one side, causing the cover to burst. In addition, in the case of a cover joined by needle punching, the bonding strength is weak, and the shape of the cover is easily deformed as the joint part is torn during repeated use. Covers installed in greenhouses such as greenhouses are repeatedly rolled or unfolded to open and close the greenhouse, and the joints easily become torn due to this repetitive work.

본 실시에에서, 융착부(44)는 고주파를 이용한 융착 공정으로 형성될 수 있다. 예를 들어 고주파 융착은 고주파수의 전류를 통해 순간적인 열을 발생시켜 솜층(21)과 부직포(22) 및 외피(30)를 접합할 수 있다.In this embodiment, the fusion portion 44 may be formed through a fusion process using high frequency. For example, high-frequency fusion can bond the cotton layer 21, the non-woven fabric 22, and the outer shell 30 by generating instantaneous heat through a high-frequency current.

도 2에 도시된 바와 같이, 본 실시예에서 융착부(44)의 폭(D)은 니들핀칭부(42) 폭(L)의 30 내지 70% 크기로 형성될 수 있다. 폭은 폭방향 길이를 의미할 수 있다. As shown in FIG. 2, in this embodiment, the width D of the fusion portion 44 may be formed to be 30 to 70% of the width L of the needle pinching portion 42. Width may mean length in the width direction.

예를 들어, 니들핀칭부(42)의 폭(L)은 50mm로 형성될 수 있으며, 이 경우 융착부(44)의 폭(44)은 15mm 내지 35mm로 형성될 수 있다. For example, the width L of the needle pinching portion 42 may be formed to be 50 mm, and in this case, the width 44 of the fusion portion 44 may be formed to be 15 mm to 35 mm.

니들핀칭부(42)의 폭(L)에 대한 융착부(44)의 폭(D)이 상기 범위보다 작은 경우에는, 접합부(40)의 접합 강도를 충분히 확보하지 못해 보온 커버(10)가 쉽게 뜯어질 수 있다. 니들핀칭부(42)의 폭(L)에 대한 융착부(44)의 폭(D)이 상기 범위보다 큰 경우에는, 보온 커부 내부의 습기가 효과적으로 배출되지 못해 내피(20)가 터지는 현상이 발생될 수 있다.If the width (D) of the fusion portion (44) relative to the width (L) of the needle pinching portion (42) is smaller than the above range, the joint strength of the joint portion (40) cannot be sufficiently secured and the thermal insulation cover (10) may easily be damaged. It can be torn. If the width (D) of the fusion portion (44) relative to the width (L) of the needle pinching portion (42) is greater than the above range, the moisture inside the thermal insulation portion cannot be discharged effectively, causing the inner skin (20) to burst. It can be.

또한, 본 실시예에서 융착부(44)는 니들핀칭부(42)의 중심부에 형성될 수 있다. 중심부라 함은 폭 방향을 따라 접합부(40)의 가운데 부분을 의미한다.Additionally, in this embodiment, the fusion portion 44 may be formed at the center of the needle pinching portion 42. The center refers to the middle portion of the joint 40 along the width direction.

이에, 보온 커버(10)의 공기층부(50) 형태를 전체적으로 안정적으로 유지하면서, 보온 커버(10)의 방향에 관계없이 공기층부(50) 내부의 습기를 안정적으로 배출시킬 수 있게 된다.Accordingly, while maintaining the overall shape of the air layer portion 50 of the thermal insulation cover 10 in a stable manner, moisture within the air layer portion 50 can be stably discharged regardless of the direction of the thermal insulation cover 10.

이하, 본 실시예의 보온 커버 제조 과정에 대해 설명하면 다음과 같다.Hereinafter, the manufacturing process of the thermal cover of this embodiment will be described as follows.

시트 형태의 솜층과 내피 및 외피를 준비하고, 준비된 솜층의 외측에 내피를 적층하여 공급한다. 솜층의 양 면에 부직포가 적층되어 연속적으로 공급될 수 있다. 이하 설명의 편의를 위해, 솜층과 내피가 적층된 구조를 보온재로 한다.Prepare a cotton layer, inner skin, and outer skin in the form of a sheet, and supply the inner skin by laminating it on the outside of the prepared cotton layer. Nonwoven fabric can be laminated on both sides of the cotton layer and supplied continuously. For convenience of explanation below, a structure in which a cotton layer and an inner layer are laminated is used as an insulating material.

그리고, 연속적으로 공급되는 보온재의 내피 표면을 따라 일정 간격으로 솜층과 내피를 1차 접합한다.Then, the cotton layer and the inner skin are first bonded at regular intervals along the inner surface of the continuously supplied insulation material.

본 실시예에서, 솜층과 내피의 1차 접합은 보온재를 니들 펀칭하여 이루어질 수 있다. 니들 펀칭 공정에 의해 보온재가 니들에 의해 촘촘하게 관통되면서 솜층과 내피의 섬유가 서로 엉켜 결합된 1차 접합부를 형성한다.In this embodiment, the primary bonding of the cotton layer and the inner skin can be accomplished by needle punching the insulation material. Through the needle punching process, the insulation material is closely penetrated by the needle, forming a primary joint where the fibers of the cotton layer and the inner skin are entangled and joined together.

니들 펀칭 공정을 통해 1차 접합이 완료되면, 준비된 외피를 보온재의 외측에 적층하여 공급한다. 보온재의 양 면에 외피가 적층되어 연속적으로 공급될 수 있다. Once the primary bonding is completed through the needle punching process, the prepared outer shell is laminated on the outside of the insulation material and supplied. The outer skin can be laminated on both sides of the insulation material and supplied continuously.

연속적으로 공급되는 보온재와 외피의 적층체를 따라 일정 간격으로 보온재와 외피를 2차 접합 한다.The insulating material and outer sheath are secondarily joined at regular intervals along the continuously supplied laminate of the insulating material and outer sheath.

본 실시예에서, 보온재와 외피의 2차 접합은, 니들펀칭 접합 영역의 일부에 상기 외피와 보온재를 열 접합하는 융착 접합 공정을 통해 이루어질 수 있다.In this embodiment, the secondary bonding of the insulation and the outer shell may be accomplished through a fusion bonding process in which the outer shell and the insulation are heat bonded to a portion of the needle punching joint area.

니들펀칭에 의해 접합된 1차 접합 영역의 일부에 대해 보온재와 외피를 열 접합하는 융착 접합 공정을 수행한다. 융착 접합 공정을 통해 솜층과 부직포 및 외피가 고온의 열과 압력에 의해 열 접합된다. A fusion bonding process is performed to thermally bond the insulation and the outer shell to a portion of the primary bonding area joined by needle punching. Through the fusion bonding process, the cotton layer, non-woven fabric, and outer shell are thermally bonded using high temperature heat and pressure.

따라서, 니들 펀칭 공정에 의한 접합 영역과 융착 접합 공정에 의한 융착 접합 영역을 갖는 접합부를 형성하여, 본 실시예의 보온 커버를 제조할 수 있다.Accordingly, the thermal cover of this embodiment can be manufactured by forming a joint having a joint area by a needle punching process and a fusion joint area by a fusion joint process.

이상 설명한 바와 같이 본 발명의 예시적인 실시예가 도시되어 설명되었지만, 다양한 변형과 다른 실시예가 본 분야의 숙련된 기술자들에 의해 행해질 수 있을 것이다. 이러한 변형과 다른 실시예들은 첨부된 청구범위에 모두 고려되고 포함되어 본 발명의 진정한 취지 및 범위를 벗어나지 않는다 할 것이다.Although exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments will occur to those skilled in the art. These modifications and other embodiments are to be considered and included in the appended claims without departing from the true spirit and scope of the present invention.
