한편, 일반적으로 많이 사용되고 있는 부직포는 장, 단섬유를 카딩하여 웹을 적층화시키고 접착 바인더를 이용하거나 열접착 방법을 이용하여 결속시킨 제품으로서 세탁이나 반복 사용시 탄성 구조가 쉽게 허물어져 탄성과 반발 회복 기능이 저하되어 완충재용 소재로의 사용에는 한계가 있었다.On the other hand, nonwoven fabrics that are commonly used are products that are laminated with webs by carding long and short fibers and bound by using an adhesive binder or a thermal bonding method. Since the function was deteriorated, there was a limit to the use of the buffer material.
따라서, 본 발명의 목적은 뛰어난 반발탄성력(복원력)과 내구성, 경량성 및 재활용 가능성이 우수하여 폴리우레탄 폼과 결합하여 사용하거나 폴리우레탄 폼의 대체재로 사용되어 카 시트 류의 커버 패드, 차량 내장재의 내피 재, 침구류의 매트리스, 방석용 패드, 브래지어 심지용, 스키복 또는 방한복의 패딩 재로 사용될 수 있는 고 탄성 부직포를 제공하는 데 있다.Accordingly, an object of the present invention is to use a combination of polyurethane foam or as a substitute for polyurethane foam to provide excellent resilience (resilience) and durability, light weight and recyclability of the car seat cover pad, vehicle interior materials To provide a highly elastic nonwoven fabric that can be used as a padding material for lining materials, bedding mattresses, cushion pads, bra wicks, ski suits, or winter clothes.

본 발명을 좀 더 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.
본 발명에 따른 고탄성 부직포는 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 10 ∼ 70중량%, 실리콘이 첨가된 오일로 표면 처리한 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 10 ∼ 70중량%, 저융점 열융착 바인더 화이버 10 ∼ 70중량% 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버 10 ∼ 70중량%로 구성되어지되 각각의 원료들을 혼합하고 카딩하여 단층 또는 다층으로 웹(web)을 적층한 다음, 적층된 웹을 미늘(barb)이 있는 니들(needle)을 이용하여 니들 펀칭하는 방법으로 결합하여 시트(sheet)를 형성하고, 시트를 건조로(dry box)와 가열로울러에 통과시켜 융착 결합시킨 것으로 특징지워진다.The high elastic nonwoven fabric according to the present invention is 10 to 70% by weight of polyester conjugate fiber, 10 to 70% by weight of polyester conjugate fiber (surface treated with oil to which silicon is added) and low melting point 10 to 70% by weight of the heat-sealed binder fiber and 10 to 70% by weight of the sheath type composite fusion fiber of polyester or polystyrene, each of the raw materials are mixed and carded to laminate a web in a single layer or multiple layers, The laminated web is joined by a needle punching method using a needle with a barb to form a sheet, and the sheet is fusion-bonded by passing through a dry box and a heating roller. Is characterized.
또한, 본 발명에 따른 고탄성 부직포의 제조 방법은 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 10 ∼ 70중량%, 실리콘이 첨가된 오일로 표면 처리한 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 10 ∼ 70중량%, 저융점 열융착 바인더 화이버 10 ∼ 70중량% 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버 10 ∼ 70중량%를 혼합하고 카딩하여 단층 또는 다층으로 웹(web)을 적층한 다음, 적층된 웹을 미늘(barb)이 있는 니들(needle)을 이용하여 니들 펀칭하는 방법으로 결합하여 시트(sheet)를 형성하고, 시트를 건조로(dry box)와 가열로울러에 통과시켜 융착 결합시키는 것으로 특징지워진다.In addition, the manufacturing method of the high elastic nonwoven fabric according to the present invention is 10 to 70% by weight of polyester conjugate fiber (polyester conjugate fiber), polyester conjugate fiber (polyester conjugate fiber) surface-treated with oil to which silicon is added 10% to 70% by weight of the low melting point heat fusion binder fiber and 10% to 70% by weight of the sheath type composite fusion fiber of polyester or polystyrene are mixed and carded to laminate a web in a single layer or multiple layers, and then laminated. It is characterized by joining the web by needle punching using a needle with barb to form a sheet, and fusion bonding the sheet through a dry box and a heating roller. .
본 발명에서 사용되는 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber)는 분자량이 서로 다른 폴리에스터 폴리머를 방사하여 섬유 가운데 기공이 형성되도록 하고, 연신과 열처리 과정을 거치면 폴리머간의 수축 차이에 의하여 스피럴 크림프(spiral crimp)가 형성되며, 고중공성으로 인하여 벌키성과 터치성이 우수해지는 섬유로서, 2 내지 10데니어의 단섬유를 사용한다.Polyester conjugate fiber used in the present invention is to spin the polyester polymer having a different molecular weight so that pores are formed in the fiber, and after stretching and heat treatment process, the spiral crimp ( spiral crimp) is formed, and as a fiber having excellent bulkiness and touchability due to its high porosity, 2 to 10 denier short fibers are used.
폴리에스터 콘쥬게이트 화이버의 심도가 10데니어를 초과할 경우에는 반발탄성력이 저하되는 단점이 있고, 2데니어 미만일 경우에는 내구성이 저하되는 문제점이 있다.When the depth of the polyester conjugate fiber exceeds 10 denier, there is a disadvantage that the resilience elasticity is lowered, when less than 2 denier there is a problem that the durability is lowered.
또한, 폴리에스터 콘쥬게이트 화이버를 단섬유 형태로 사용하지 않을 경우에는 다른 화이버들과 혼합이 용이하지 않아 균질한 제품을 얻기 어려운 단점이 있다.In addition, when the polyester conjugate fiber is not used in the form of short fibers, it is difficult to obtain a homogeneous product because it is not easily mixed with other fibers.
폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber)는 10 ∼ 70중량% 사용되는 것이 바람직하며, 사용량이 10중량% 미만일 경우에는 첨가 효과가 미약하여 반발탄성력이 저하되는 단점이 있을 뿐만 아니라 저융점 열융착 바인더 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버와의 융착이 용이하지 못해 내구성이 저하됨은 물론 저융점 열융착 바인더 화이버 10 ∼ 70중량% 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 증가하여 경량화가 어려운 단점이 있으며, 70중량%를 초과할 경우에는 저융점 열융착 바인더 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 적어 융착이 잘 이루어지지 않는 문제점이 있다.Polyester conjugate fiber (polyester conjugate fiber) is preferably used in 10 to 70% by weight, if the amount is less than 10% by weight, the addition effect is weak and the resilience elasticity is reduced as well as low melting point hot melt binder It is not easy to fusion with fiber and polyester or polystyrene, and it is not easy to be fused with the deep fusion composite fusion fiber, and the durability is lowered. When the weight is more than 70% by weight, there is a problem in that the low melting point heat fusion binder fiber and the amount of the deep seam composite fusion fiber of polyester or polystyrene are less used and the fusion is difficult.
실리콘이 첨가된 오일로 표면 처리한 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber)는 실리콘이 첨가된 오일로 표면 처리한 것을 제외하고는 상술한 폴리에스터 콘쥬게이트 화이버와 동일한 것을 사용한다.The polyester conjugate fiber surface-treated with the oil to which silicon is added is the same as the polyester conjugate fiber described above except that the surface is treated with the oil to which silicon is added.
실리콘이 첨가된 오일로 표면 처리한 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 역시 심도가 2 내지 10데니어인 단섬유를 사용하는 것이 바람직하며, 심도가 10데니어를 초과할 경우에는 반발탄성력이 저하되는 단점이 있고, 2데니어 미만일 경우에는 내구성이 저하되는 문제점이 있으며, 단섬유 형태로 사용하지 않을 경우에는 다른 화이버들과 혼합이 용이하지 않아 균질한 제품을 얻기 어려운 단점이 있다.Polyester conjugate fibers surface-treated with oils containing silicon are also preferably short fibers having a depth of 2 to 10 denier. If the depth exceeds 10 denier, the rebound elasticity is lowered. If there is a disadvantage, less than 2 denier has a problem that the durability is lowered, when not used in the form of short fibers it is difficult to obtain a homogeneous product because it is not easy to mix with other fibers.
실리콘이 첨가된 오일로 표면 처리한 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber)는 열융착시 표면에 처리된 오일로 인하여 다른 화이버들과 융착이 일어나지 않아 탄성력을 유지하도록 하는 작용을 하고, 10 ∼ 70중량% 사용되는 것이 바람직하며, 사용량이 10중량% 미만일 경우에는 첨가 효과가 미약하여 반발탄성력이 저하되는 단점이 있을 뿐만 아니라 저융점 열융착 바인더 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 증가하여 경량화가 어려운 단점이 있으며, 70중량%를 초과할 경우에는 폴리에스터 콘쥬게이트 화이버, 저융점 열융착 바인더 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 적어 폴리에스터 콘쥬게이트 화이버와 저융점 열융착 바인더 화이버 및/또는 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 융착이 잘 이루어지지 않는 문제점이 있다.Polyester conjugate fiber surface-treated with an oil added with silicone acts to maintain elasticity because the surface-treated oil does not fuse with other fibers when thermally fused. It is preferred to be used in a weight percent, if the amount is less than 10% by weight, the addition effect is weak and the rebound elasticity is reduced, as well as the low melting point heat-sealing binder fiber and polyester or polystyrene core sheath composite fusion fiber This increases the weight and makes it difficult to reduce the weight. If it exceeds 70% by weight, polyester conjugate fibers, low melting point heat-sealed binder fibers, and polyester or polystyrene core sheath-type composite fusion fibers have low amounts of polyester conjugate fibers. And low melting point hot melt binder fibers and / or poly Emitter, or there is a problem in the core-sheath type fusion bonding of the composite fibers of the polystyrene that is not well done.
저융점 열융착 바인더 화이버로는 융점이 80 ∼ 160℃이고, 표면 처리가 행하여지지 않았으며, 크림프가 형성되지 않은 폴리에스터 또는 폴리스티렌 섬유로서 섬도가 2 내지 10데니어인 단섬유를 사용하는 것이 바람직하다.As the low melting point heat-sealing binder fiber, it is preferable to use short fibers having a melting point of 80 to 160 DEG C, no surface treatment, and no crimped polyester or polystyrene fibers having fineness of 2 to 10 denier. .
저융점 열융착 바인더 화이버의 융점이 80℃ 미만일 경우에는 내열성이 현저히 저하되는 단점이 있고, 160℃를 초과할 경우에는 열융착시 고온을 사용하여야 하므로 화이버가 손상될 우려가 있을 뿐만 아니라 열융착에 많이 에너지가 사용되어야 하는 문제점이 있다.If the melting point of the low melting point heat-sealed binder fiber is less than 80 ° C., the heat resistance is remarkably lowered. If the melting point is higher than 160 ° C., the high temperature should be used during heat-sealing, which may damage the fiber and cause heat-sealing. There is a problem that much energy must be used.
저융점 열융착 바인더 화이버는 폴리에스터 콘쥬게이트 화이버(polyester conjugate fiber) 및/ 또는 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버와의 융착이 용이하게 이루어지도록 하기 위하여 표면 처리를 하지 않아야 하며, 크림프가 형성되면 융착이 않되는 부분이 발생하여 내구성이 저하되는 문제점이 있고, 심도가 10데니어를 초과할 경우에는 반발탄성력이 저하되는 단점이 있고, 2데니어 미만일 경우에는 내구성이 저하되는 문제점이 있으며, 단섬유 형태로 사용하지 않을 경우에는 다른 화이버들과 혼합이 용이하지 않아 균질한 제품을 얻기 어려운 단점이 있다.Low melting point thermobond binder fibers should not be surface treated to facilitate fusion with polyester conjugate fibers and / or polyester or polystyrene deep fusion composite fusion fibers, and crimped If there is a problem that the fusion does not occur and the durability is lowered, when the depth exceeds 10 denier has a disadvantage that the resilience elasticity is lowered, if less than 2 denier there is a problem that the durability is reduced, short fibers If it is not used in the form, it is difficult to obtain a homogeneous product because it is not easy to mix with other fibers.
저융점 열융착 바인더 화이버는 10 ∼ 70중량% 사용되는 것이 바람직하며, 사용량이 10중량% 미만일 경우에는 폴리에스터 콘쥬게이트 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 적어 폴리에스터 콘쥬게이트 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 융착이 잘 이루어지지 않는 문제점이 있고, 70중량%를 초과할 경우에는 폴리에스터 콘쥬게이트 화이버의 사용량이 저하되어 반발탄성력이 저하되는 단점이 있다.The low melting point heat-sealed binder fiber is preferably used in an amount of 10 to 70% by weight, and when the amount is less than 10% by weight, the polyester conjugate fiber and the polyester or polystyrene deep sheath composite fusion fiber have a low amount of polyester conjugate. There is a problem in that the fusion of the fiber and polyester or polystyrene deep fusion composite fusion fiber is not well made, and when it exceeds 70% by weight, the amount of the polyester conjugate fiber is lowered and the rebound elasticity is lowered.
폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버는 융점이 높은 폴리머가 내부에, 융점이 낮은 폴리머가 표면에 형성된 심초형 화이버로서 부드럽고 탄성이 좋으며, 표면을 구성하는 융점이 낮은 폴리머가 다른 황이버들과 융착이 용이하도록 하고, 열융착후 원단의 성질이 부드럽고 탄성이 뛰어난 제품으로서의 효과 를 발현하게 하는 것으로, 10 ∼ 70중량% 사용되는 것이 바람직하며, 사용량이 10중량% 미만일 경우에는 폴리에스터 콘쥬게이트 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 사용량이 적어 폴리에스터 콘쥬게이트 화이버 및 폴리에스터 또는 폴리스티렌의 심초형 복합 융착 화이버의 융착이 잘 이루어지지 않는 문제점이 있고, 70중량%를 초과할 경우에는 폴리에스터 콘쥬게이트 화이버의 사용량이 저하되어 반발탄성력이 저하되는 단점이 있다.Echo type composite fusion fiber made of polyester or polystyrene is an effervescent type fiber with high melting point inside and low melting point polymer on the surface. It is soft and elastic, and low melting point polymer fused with other sulfur fibers. To facilitate this, it is preferable to use 10 to 70% by weight, and when the amount of use is less than 10% by weight, to express the effect as a product having a soft and elastic property of the fabric after heat fusion and excellent elasticity. There is a problem that the polyester conjugated fiber and polyester or polystyrene deep fusion composite fusion fibers are difficult to be fused due to the low amount of polyester or polystyrene deep fusion composite fusion fibers, and when it exceeds 70% by weight The amount of ester conjugated fiber There is a disadvantage that the resisting spring force to decrease.
제조된 고탄성 부직포는 단독으로 사용될 수도 있고, 폴리우레탄 발포체와 스판본드(부직포)와 결합시켜 사용할 수도 있다.The prepared high elastic nonwoven fabric may be used alone or in combination with a polyurethane foam and a spanbond (nonwoven fabric).
