Abstract

본 발명에 따른 건조기용 진동방지 패드는 방적 후 폐기되는 천연섬유, 특히 양모에 합성섬유를 혼합하여 제조함으로써 마찰계수를 낮추고 마찰에 따른 마모를 감소시킬 수 있다. 또한 충분한 벌키성을 확보함으로써 진동과 이에 따른 소음을 크게 줄일 수 있다.
여기에 천연섬유의 방적 시 사용하는 방적유의 조성을 특정함으로써 내열성, 내마모성 및 내충격성을 더욱 높여 패드의 사용수명을 연장함과 동시에 진동, 소음을 줄이고 건조기의 사용전력을 낮추는 효과를 가진다.The anti-vibration pad for a dryer according to the present invention can lower the coefficient of friction and reduce wear due to friction by manufacturing it by mixing synthetic fibers with natural fibers, especially wool, which are discarded after spinning. Additionally, by ensuring sufficient bulkiness, vibration and resulting noise can be greatly reduced.
In addition, by specifying the composition of the spinning oil used when spinning natural fibers, heat resistance, abrasion resistance, and impact resistance are further increased, which has the effect of extending the service life of the pad, reducing vibration and noise, and lowering the power usage of the dryer.

Description

건조기용 진동방지 패드 및 이의 제조방법{A anti-vibration pad for clothes dryer}Anti-vibration pad for dryer and manufacturing method thereof {A anti-vibration pad for clothes dryer}

본 발명은 건조기용 진동방지 패드 및 이의 제조방법에 관한 것으로, 상세하게는 세탁물 건조용 건조기의 드럼 양단부에 설치되어 세탁물을 건조하기 위하여 드럼에 열풍을 공급할 때에 그 공급되는 열풍의 누기를 방지함과 동시에 내마모성과 내충격성, 내진동성을 달성할 수 있는 건조기용 진동방지 패드 및 이의 제조방법에 관한 것이다.The present invention relates to an anti-vibration pad for a dryer and a method of manufacturing the same. Specifically, the present invention relates to an anti-vibration pad for a dryer and a method of manufacturing the same. Specifically, it is installed at both ends of a drum of a dryer for drying laundry and prevents leakage of the supplied hot air when hot air is supplied to the drum for drying laundry. It relates to an anti-vibration pad for a dryer that can achieve wear resistance, impact resistance, and vibration resistance at the same time, and a method of manufacturing the same.

일반적으로 세탁물을 건조하는 건조기는 그 내부에 드럼이 설치되게 되고, 그 드럼의 내부에는 세탁물을 건조하기 위한 열풍이 공급되어 상기 세탁물을 건조하게 되는데, 이때 상기 드럼으로 공급되는 열풍이 외부로 누기 되는 것을 방지하기 위하여 드럼의 양단부에 실링용 가스켓 패드가 설치된다.In general, a dryer for drying laundry has a drum installed inside the drum, and hot air for drying the laundry is supplied to the inside of the drum to dry the laundry. At this time, the hot air supplied to the drum leaks to the outside. To prevent this, sealing gasket pads are installed on both ends of the drum.

한편 상기 세탁물 건조기는 세탁이 완료된 젖은 상태의 세탁물을 자동으로 건조시켜 주는 기기로서, 건조기 본체의 내부에 회동가능한 드럼과, 그 드럼을 회동시키는 구동장치와, 상기 드럼의 앞쪽과 뒤쪽을 막아 건조공간을 형성하고 드럼의 선단과 후단을 지지하는 프론트서포터 및 리어서포터와, 고온 건조한 열풍을 만드는 히터가 구비되어 세탁을 자동으로 건조시킨다.Meanwhile, the laundry dryer is a device that automatically dries wet laundry that has been washed, and includes a rotatable drum inside the dryer body, a driving device that rotates the drum, and a drying space that blocks the front and back of the drum. It is equipped with a front supporter and a rear supporter that support the front and rear ends of the drum, and a heater that generates high-temperature dry hot air to automatically dry the laundry.

상술된 구조를 갖는 세탁물 건조기의 프론트서포터와 드럼 및 리어서포터와 드럼 사이에는 열풍의 누기를 방지하기 위한 펠트(felt) 소재의 가스켓 패드가 설치된다.A gasket pad made of felt is installed between the front supporter and the drum and the rear supporter and the drum of the laundry dryer having the above-described structure to prevent leakage of hot air.

이러한 가스켓 패드는 드럼의 선단과 후단의 외주 연을 감싼 채로 접착제로 접착되어 설치되는데, 이때 상기 가스켓 패드가 열풍에 장시간 영향을 받으면 드럼에서 분리되거나 신축성이 상실되어 실링성이 저하되는 문제점이 발생한다.These gasket pads are installed by attaching them with an adhesive while covering the outer edge of the front and rear ends of the drum. At this time, if the gasket pad is affected by hot air for a long time, it may separate from the drum or lose elasticity, causing a problem of deterioration of sealing performance. .

가스켓 패드와 관련된 선행문헌으로는 공개번호 제10-2010-0037382호의 "열가소성 엘라스토머 및 이로 제조된 드럼세탁기용 가스켓" 등이 제공되어 있으나, 이들은 모두 가스켓 패드를 장시간 사용하게 되면 열변형 되거나 그로 인한 실링력의 저하가 발생하였으며, 건조기의 가동 시 발생하는 진동을 억제하는 효과가 현저히 떨어지는 문제점이 발생하였다.Prior literature related to gasket pads includes Publication No. 10-2010-0037382 titled “Thermoplastic elastomer and gaskets for drum washing machines made therefrom,” but these are all subject to thermal deformation or sealing if the gasket pad is used for a long period of time. A decrease in power occurred, and a problem occurred in which the effect of suppressing vibration occurring when the dryer was operated was significantly reduced.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 드럼의 선/후단을 감싸며 실링하는 가스켓 패드에서 그 공급되는 열풍의 누기를 방지함과 동시에 내마모성과 내충격성, 내진동성을 달성할 수 있는 건조기용 진동방지 패드 및 이의 제조방법의 제공을 목적으로 한다. The present invention was developed to solve the above problems, and prevents leakage of hot air supplied from the gasket pad that surrounds and seals the front and rear ends of the drum, while achieving wear resistance, impact resistance, and vibration resistance. The purpose is to provide an anti-vibration pad for a dryer and a manufacturing method thereof.

The anti-vibration pad for a dryer according to the present invention can lower the coefficient of friction and reduce wear caused by friction by mixing synthetic fibers with natural fibers, especially wool, which are discarded after spinning. Additionally, by ensuring sufficient bulkiness, vibration and resulting noise can be greatly reduced.

여기에 천연섬유의 방적 시 사용하는 방적유의 조성을 특정함으로써 내열성, 내마모성 및 내충격성을 더욱 높여 패드의 사용수명을 연장함과 동시에 진동, 소음을 줄이고 건조기의 사용전력을 낮추는 효과를 가진다.In addition, by specifying the composition of the spinning oil used when spinning natural fibers, heat resistance, abrasion resistance, and impact resistance are further increased, which has the effect of extending the service life of the pad, reducing vibration and noise, and lowering the power usage of the dryer.

본 발명에서 펠트원단은 니들펀칭에 의해 제조되는 부직포(non woven fabric)를 뜻하는 것으로, 단섬유 또는 장섬유를 바늘로 교락하여 엉키게 함으로써 제조되는 원단을 뜻한다. 이렇게 제조된 펠트원단은 다양한 기공에 의해 벌키성, 흡음성, 차폐성을 확보할 수 있으며, 제조방법이 간단하고 우수한 내구성을 가질 수 있다.In the present invention, felt fabric refers to a non-woven fabric manufactured by needle punching, and refers to a fabric manufactured by entangling short fibers or long fibers with a needle.

를 포함할 수 있다.may include.

본 발명에서 상기 a) 단계는 원단섬유를 제조하는 단계로, 천연섬유와 합성섬유를 혼합하여 시트 형태로 제조하는 단계이다.In the present invention, step a) is a step of manufacturing fabric fibers, and is a step of mixing natural fibers and synthetic fibers to form a sheet.

본 발명에서 상기 천연섬유는 화학적 가공을 거친 인조섬유와 다르게 쾌적성이 뛰어나며, 특히 통기성, 흡수성이 우수하고 건조가 빠르기 때문에 마찰에 따른 정전기의 발생을 억제할 수 있다.In the present invention, the natural fiber has excellent comfort, unlike chemically processed artificial fibers. In particular, it has excellent breathability and absorbency and dries quickly, so it can suppress the generation of static electricity due to friction.

본 발명에서 상기 천연섬유로 예를 들면 모섬유, 면섬유, 마섬유 및 견섬유 등을 들 수 있으며, 이들 중 모섬유를 사용하는 것이 가장 바람직하다.In the present invention, examples of the natural fibers include wool fibers, cotton fibers, hemp fibers, and silk fibers, and among these, it is most preferable to use wool fibers.

상기 모섬유는 자체에 친수기가 많고 비결정 부분이 많아 섬유 중 가장 흡습성이 큰 섬유 중에 하나로서(흡수성: 14 내지 16%)로 섬유 자체의 무게의 30%까지 흡수하는 것으로 알져져 있다. 또한 수분 흡수 시 표면에 소수성 스케일층에 의한 발수성에 의해 물을 튕기며, 이에 따라 수분을 많이 흡수해도 별로 젖은 감을 주지 않아 쾌적함을 주며, 물결모양의 천연 권축은 원단섬유에 통기성과 신축성, 내진동성 등을 갖게 한다. 또한 축융성이 있고 표면에 스케일을 가지고 있어 서로 쉽게 엉키기 때문에 각 섬유들 간의 결합력을 증대시킬 수 있어 내마모성 등의 기계적 강도를 높일 수 있다.The hair fiber is one of the most hygroscopic fibers among fibers because it has many hydrophilic groups and many amorphous parts (absorbency: 14 to 16%), and is known to absorb up to 30% of the weight of the fiber itself. In addition, when moisture is absorbed, the water is repelled by the hydrophobic scale layer on the surface, which does not give a wet feeling even if a lot of moisture is absorbed, providing comfort. The wave-shaped natural crimp gives the fabric fibers breathability, elasticity, and vibration resistance. Have your back. In addition, since it is condensable and has scales on the surface, it is easily tangled with each other, so the bonding force between each fiber can be increased, thereby increasing mechanical strength such as abrasion resistance.

본 발명에서 상기 모섬유는 방적공정을 거친 의류용 모섬유를 사용하여도 좋으나, 제조원가를 절감하기 위해 방적공정에서 발생한 폐섬유를 사용하는 것이 바람직하다. 특히 제품화 과정에서 발생하는 스크랩을 타면공정 처리하여 생산된 재활용 섬유를 사용하는 경우, 일반 모섬유와 동일한 진동 및 소음 감소 효과를 달성하면서도 제조비용을 줄여주는 효과를 가진다.In the present invention, the wool fiber may be clothing wool fiber that has undergone a spinning process, but it is preferable to use waste fiber generated in the spinning process to reduce manufacturing costs. In particular, when using recycled fiber produced by processing scrap generated during the commercialization process, it has the effect of reducing manufacturing costs while achieving the same vibration and noise reduction effects as regular wool fiber.

이때 상기 천연섬유, 특히 모섬유는 섬유에 방적성능을 부여하고 사질을 향상시키기 위해 방적 유제를 사용하여 표면처리하는 것이 좋다.At this time, it is recommended that the natural fibers, especially wool fibers, be surface treated using a spinning emulsion to provide spinning performance to the fiber and improve yarn quality.

일반적으로 섬유 덩어리를 펴고 당겨서 가지런히 하여 꼬임을 주어 실을 제조하는 방적 공정에 있어서는, 섬유 상호 및 섬유와 방적 기계를 구성하는 금속 또는 고무 등의 접촉부와의 사이에 마찰이 중요한 요소로 작용하는데, 특히 모섬유는 기본적으로 표면에 스케일을 가지고 있으며, 구부러진 경우가 많기 때문에 섬유 덩어리를 펴고 당기는 것 자체가 상당한 힘을 소비한다. 또한 섬유 제조 과정에서 연속되는 방적 작업으로 발생한 열에 의해 실이 끊어지는 현상이 종종 발생하게 된다.In general, in the spinning process of manufacturing yarn by stretching, pulling, aligning, and twisting a mass of fibers, friction is an important factor between the fibers and the contact parts such as metal or rubber that make up the fiber and the spinning machine. In particular, hair fibers basically have scales on the surface and are often bent, so stretching and pulling the fiber mass itself consumes a considerable amount of force. Additionally, during the textile manufacturing process, thread breakage often occurs due to heat generated during continuous spinning operations.

본 발명은 이러한 문제점을 해결함과 동시에 제조되는 패드의 진동 흡수 효과 및 내마모성을 더욱 항상시키기 위해 상기 합성섬유와 혼섬되기 전에 상술한 방적유로 표면처리를 진행하는 것이 좋다.In order to solve this problem and further improve the vibration absorption effect and wear resistance of the manufactured pad, the present invention recommends surface treatment with the above-described spinning oil before mixing with the synthetic fiber.

It is preferable to include 1 to 10 parts by weight and 1 to 5 parts by weight of additives.

상기 광물유는 주로 원유를 정제하는 과정에서 생성되는 부산물로서, 주성분은 알칸(alkane)과 파라핀이며, 이들의 예를 들면 미네랄오일 파라핀왁스, 페트롤라툼 오일 등을 포함하며, 정제과정의 정도에 따라 감압 증류유, 산처리유, 용매처리유, 수소처리유, 화이트오일, 방향족유, 혼합유 등을 포함할 수 있다. The mineral oil is mainly a by-product produced in the process of refining crude oil, and its main components are alkane and paraffin. Examples of these include mineral oil, paraffin wax, petrolatum oil, etc., and are depressurized depending on the degree of the refining process. It may include distilled oil, acid-treated oil, solvent-treated oil, hydrogen-treated oil, white oil, aromatic oil, mixed oil, etc.

상기 광물유는 기타 물성을 한정하지는 않으나, 동점도가 40℃에서 8cSt 내지 96cSt인 것이 좋다. 동점도가 상기 범위 미만인 경우 윤활성이 불충분할 수 있으며, 상기 범위 초과인 경우 점도 과다로 인해 작업성이 떨어지고 쉽게 오염될 수 있다.The mineral oil is not limited to other physical properties, but it is preferred that the kinematic viscosity is 8 cSt to 96 cSt at 40°C. If the kinematic viscosity is below the above range, lubricity may be insufficient, and if it is above the above range, workability may be poor and easily contaminated due to excessive viscosity.

본 발명에서 상기 알칼리 금속염은 대전방지성을 향상시키기 위해 첨가하는 것으로, 나트륨 또는 칼륨염, 특히 이들의 스테아레이트가 바람직하며, 첨가량을 한정하는 것은 아니나 상기 광물유 100 중량부 대비 1 내지 10 중량부를 첨가하는 것이 윤활성 등을 해치지 않으면서도 충분한 대전방지성을 확보할 수 있다.In the present invention, the alkali metal salt is added to improve antistatic properties, and sodium or potassium salts, especially their stearates, are preferred. The amount added is not limited, but is added at 1 to 10 parts by weight relative to 100 parts by weight of the mineral oil. This ensures sufficient antistatic properties without compromising lubrication, etc.

상기 실록산계 유제는 평활성, 집속성을 높이기 위해 첨가하는 것으로, 특히 폴리디메틸실록산은 조성물의 표면장력을 크게 낮춤으로써 확전성(쉽게 펴지는 성질), 침투성이 강하고, 얇은 피막을 형성할 수 있으며, 온도에 의한 점도 변화를 줄이고 내화학성을 높이며, 동시에 마찰계수를 낮출 수 있기 때문에 내마찰성과 내진동성을 동시에 상승시키는 효과를 달성할 수 있다.The siloxane-based emulsion is added to increase smoothness and cohesion. In particular, polydimethylsiloxane significantly lowers the surface tension of the composition, has strong spreadability and permeability, and can form a thin film. By reducing the change in viscosity due to temperature, increasing chemical resistance, and lowering the friction coefficient at the same time, it is possible to achieve the effect of simultaneously increasing friction resistance and vibration resistance.

상기 실록산계 유제는 상기 광물유 100 중량부 대비 10 내지 30 중량부 첨가하는 것이 좋다. 실록산계 유제가 상기 범위 미만 첨가되는 경우 상술한 내마찰성, 내진동성의 상승 효과를 달성하기 어려우며, 상기 범위를 초과하는 경우 평활성 및 집속성이 크게 떨어질 수 있다.It is recommended to add 10 to 30 parts by weight of the siloxane-based emulsion based on 100 parts by weight of the mineral oil. If the siloxane-based emulsion is added below the above range, it is difficult to achieve the synergistic effect of friction resistance and vibration resistance described above, and if it exceeds the above range, smoothness and focusing properties may be significantly reduced.

상기 폴리올은 조성물의 대전방지성, 고온안정성을 높이기 위해 첨가하는 것으로, 일예로 폴리에틸렌글리콜 등을 들 수 있다. 특히 상기 폴리에틸렌글리콜은 조성물의 혼합 후 방치 시 시간 경과에 따른 조성물의 상분리를 방지할 수 있어 바람직하다.The polyol is added to increase antistatic properties and high temperature stability of the composition, and examples include polyethylene glycol. In particular, the polyethylene glycol is preferred because it can prevent phase separation of the composition over time when the composition is left to stand after mixing.

상기 폴리올은 분자량을 한정하지 않으나 100 내지 1,000의 중량평균분자량을 갖는 것이 바람직하며, 첨가량은 상기 광물유 100 중량부 대비 1 내지 10 중량부를 첨가하는 것이 상술한 경시안정성을 확보할 수 있어 바람직하다.The molecular weight of the polyol is not limited, but it is preferable to have a weight average molecular weight of 100 to 1,000, and the addition amount is preferably 1 to 10 parts by weight based on 100 parts by weight of the mineral oil to ensure the above-mentioned aging stability.

상기 첨가제는 조성물의 물성, 특히 윤활성, 내열성을 향상시키기 위해 첨가하는 것으로, 상기 목적을 해치지 않는 한에서 종류를 한정하지 않는다. 이러한 첨가제로 예를 들면 알코올, 물 등의 용매; 수산화칼륨, 초산칼륨 등의 알칼리 성분; 콜로이달 실리카, 이산화티탄 등의 충전재; 폴리옥시에틸렌 알킬에테르; 채종유, 피마자유 등의 유제; 등을 포함할 수 있다. The additive is added to improve the physical properties of the composition, especially lubricity and heat resistance, and the type is not limited as long as it does not impair the above purpose. Examples of such additives include solvents such as alcohol and water; Alkaline components such as potassium hydroxide and potassium acetate; Fillers such as colloidal silica and titanium dioxide; polyoxyethylene alkyl ether; Emulsions such as rapeseed oil and castor oil; It may include etc.

특히 상기 충전재로 바람직하게는 탈크 및 실리카의 혼합물을 사용하는 것이 바람직하다. 상기 탈크는 내마찰성을 줄이는 효과를 가지며, 상기 실리카는 내마모성을 높이는 효과를 가진다. In particular, it is preferable to use a mixture of talc and silica as the filler. The talc has the effect of reducing friction resistance, and the silica has the effect of increasing wear resistance.

이러한 첨가제는 첨가량 또한 한정하지 않으며, 예를 들어 상기 광물유 100 중량부 대비 각각의 첨가제 1 내지 500 중량부를 포함하는 것이 좋다.The amount of these additives is not limited, and for example, it is recommended to include 1 to 500 parts by weight of each additive relative to 100 parts by weight of the mineral oil.

또한 상기 방적유는 충격과 진동을 흡수하고 내마모성을 더욱 높이기 위해 바인더 및 탄성체 입자를 더 포함할 수 있다.In addition, the spinning oil may further include a binder and elastomer particles to absorb shock and vibration and further increase wear resistance.

상기 바인더는 상기 탄성체 입자를 상기 천연섬유 표면에 부착하기 위해 첨가하는 것으로, 상술한 조성물 내 용매에 용해될 수 있는 것이라면 종류에 한정치 않는다.The binder is added to attach the elastic particles to the surface of the natural fiber, and the type is not limited as long as it can be dissolved in the solvent in the composition described above.

상기 바인더로 예를 들면 비닐 알코올-비닐 아세테이트 공중합체(vinyl alcohol-vinyl acetate copolymer), 폴리비닐 피롤리돈(polyvinyl pyrolidone), 폴리비닐 알코올(polyvinyl alcohol), 카제인(casein), 콩 단백질(soya protein), 젤라틴(gelatine) 및 리그닌 술포네이트(lignin sulphonate) 등이 있으며, 이들은 단독으로 또는 둘 이상 혼합하여 사용하여도 좋다.Examples of the binder include vinyl alcohol-vinyl acetate copolymer, polyvinyl pyrolidone, polyvinyl alcohol, casein, and soy protein. ), gelatin, and lignin sulphonate, etc., and these may be used alone or in a mixture of two or more.

상기 바인더로 바람직하게는 폴리비닐 알콜을 들 수 있다. 상기 폴리비닐알콜은 상술한 용매들에 쉽게 용해되어 작업성이 우수하며, 화학적 안정성과 절연성이 우수하기 때문에 반복적인 마찰에도 열에 의한 변형이 발생하지 않고 탄성체 입자를 잡아두는 역할을 할 수 있다.The binder is preferably polyvinyl alcohol. The polyvinyl alcohol is easily soluble in the above-mentioned solvents and has excellent workability, and because it has excellent chemical stability and insulation, it can serve to hold elastic particles without causing thermal deformation even after repeated friction.

상기 폴리비닐알콜은 중합도 등을 한정하는 것은 아니나, 중합도(polymerisation degree)는 2,000 내지 3,000, 중량평균분자량은 10,000 내지 100,000 g/mol인 것이 상술한 물성을 가질 수 있어 바람직하다.The degree of polymerization of the polyvinyl alcohol is not limited, but it is preferable that the polymerization degree is 2,000 to 3,000 and the weight average molecular weight is 10,000 to 100,000 g/mol so that it can have the above-mentioned physical properties.

상기 바인더는 광물유 100 중량부 대비 10 내지 30 중량부 첨가하는 것이 좋다. 바인더가 상기 범위 미만으로 첨가되는 경우 탄성체의 부착 효과가 미비하며, 상기 범위를 초과하는 경우 조성물의 점성 증가로 인해 작업성이 크게 떨어질 수 있다.It is recommended to add 10 to 30 parts by weight of the binder based on 100 parts by weight of mineral oil. If the binder is added below the above range, the adhesion effect of the elastic body is minimal, and if the binder is added above the above range, workability may be greatly reduced due to increased viscosity of the composition.

본 발명에서 상기 탄성체는 패드의 충격 흡수, 진동 흡수 효과를 높이기 위해 첨가하는 것으로, 폴리우레탄을 주성분으로 하기 때문에 신축성이 우수한 고무 탄성을 발현할 수 있다. In the present invention, the elastic body is added to increase the shock absorption and vibration absorption effects of the pad, and because it is mainly composed of polyurethane, it can exhibit rubber elasticity with excellent elasticity.

상기 탄성체는 일반적인 폴리우레탄의 제조방법, 즉 폴리올과 이소시아네이트를 중합함으로써 제조할 수 있으며, 필요에 따라 사슬연장제를 더 첨가하여 반응시킬 경우 입자의 크기를 조절할 수 있다.The elastomer can be manufactured by a general polyurethane manufacturing method, that is, by polymerizing polyol and isocyanate, and if necessary, the particle size can be adjusted by adding a chain extender for reaction.

이때 상기 폴리올로는 에테르계, 에스테르계, 폴리카프로락톤계, 폴리카보네이트계 폴리올들을 사용할 수 있으며, 이소시아네이트로는 파라-페닐렌 디이소시아네이트를 포함하는 것이 바람직하다. 또한 사슬연장제는 통상적으로 사용되는 4,4-메틸렌비스(2-클로로아닐린)(4,4-Methylenebis(2-chloroaniline)), 1,4-부탄디올(1,4-butanediol), 트리메틸올프로판(Trimethylolpropane), m페닐렌디아민(Phenylene diamine), 디에틸톨루엔디아민(Diethyltoluenediamine), 헥사메틸렌디아민(hexamethylenediamine) 등에서 하나 또는 복수를 포함하는 것이 좋다. 또한 이들의 첨가량을 한정하는 것은 아니나 폴리올과 이소시아네이트가 1 : 1 내지 1.3 중량비로 첨가하며, 상기 사슬연장제는 폴리올 100 중량부 대비 0.1 내지 20 중량부 첨가하는 것이 좋다.At this time, ether-based, ester-based, polycaprolactone-based, and polycarbonate-based polyols can be used as the polyol, and the isocyanate preferably includes para-phenylene diisocyanate. In addition, commonly used chain extenders include 4,4-Methylenebis(2-chloroaniline), 1,4-butanediol, and trimethylolpropane. It is recommended to include one or more of (Trimethylolpropane), m-phenylene diamine, diethyltoluenediamine, and hexamethylenediamine. In addition, the amount of addition is not limited, but polyol and isocyanate are added at a weight ratio of 1:1 to 1.3, and the chain extender is preferably added at 0.1 to 20 parts by weight based on 100 parts by weight of polyol.

상기 탄성체는 입자 형태로 첨가되는 것이 좋으며, 이때 입자의 직경을 한정하지 않으나, 0.1 내지 5 ㎜의 크기를 갖는 것이 바람직하다. 또한 상기 탄성체는 상기 광물유 100 중량부 대비 10 내지 50 중량부 포함하는 것이 바람직하다.The elastic body is preferably added in the form of particles, and the diameter of the particles is not limited, but preferably has a size of 0.1 to 5 mm. In addition, the elastic body preferably contains 10 to 50 parts by weight based on 100 parts by weight of the mineral oil.

본 발명은 상기 방적유의 적용 방법을 한정하지 않는다. 일예로 상기 방적유 조성물이 담겨진 욕조에 상기 천연섬유를 담지하거나, 방적유의 분무 액적에 천연섬유를 통과시켜 적용하는 것이 바람직하다. 이때 상기 방적유의 급유분으로는 0.5 내지 1%(o.p.u, Oil Pick-Up)가 되도록 하는 것이 좋다.The present invention does not limit the application method of the spinning oil. For example, it is preferable to apply the natural fibers by placing them in a bathtub containing the spinning oil composition or by passing the natural fibers through spray droplets of the spinning oil. At this time, it is recommended that the oil content of the spinning oil be 0.5 to 1% (o.p.u, Oil Pick-Up).

본 발명에서 상기 합성섬유는 상기 천연섬유, 특히 모섬유의 단점인 약한 내구성과 기계적 물성을 보완하기 위해 첨가하는 것으로, 종류를 한정하는 것은 아니나 폴리에틸렌, 폴리프로필렌, 폴리부틸렌 등의 폴리올레핀, 폴리에스테르, 폴리아미드, 폴리아크릴 및 레이온에서 선택되는 어느 하나 또는 복수를 포함할 수 있다.In the present invention, the synthetic fiber is added to compensate for the weak durability and mechanical properties, which are the disadvantages of the natural fiber, especially wool fiber, and is not limited to the type, but includes polyolefin such as polyethylene, polypropylene, and polybutylene, polyester, It may include one or more selected from polyamide, polyacrylic, and rayon.

본 발명에서 상기 합성섬유로 바람직하게는 폴리에틸렌을 들 수 있다. 폴리에틸렌 섬유는 합성, 제조가 쉽고 밀도 등을 조절함에 따라 원하는 기계적 물성을 확보할 수 있기 때문이다. 예를 들어 상기 폴리에틸렌 섬유는 중합되는 고분자의 점도를 조절하여 고강도, 저수축의 물성을 발현할 수도 있으며, 분자량 분포의 조절을 통해 내열성을 조절할 수도 있다.In the present invention, the synthetic fiber is preferably polyethylene. This is because polyethylene fibers are easy to synthesize and manufacture, and desired mechanical properties can be secured by controlling density, etc. For example, the polyethylene fiber can exhibit high strength and low shrinkage properties by adjusting the viscosity of the polymer being polymerized, and heat resistance can be adjusted by adjusting the molecular weight distribution.

본 발명은 이러한 물성을 제한하지 않으며, 예를 들어 용융지수가 0.6 내지 2 g/10min, 분자량 분포지수가 1 내지 10이며, 주요 반복단위가 에틸렌인 폴리에틸렌 수지로 방사된 섬유이면 족하다.The present invention does not limit these physical properties, and for example, a fiber spun from a polyethylene resin having a melt index of 0.6 to 2 g/10 min, a molecular weight distribution index of 1 to 10, and the main repeating unit of ethylene is sufficient.

또한 본 발명에 따른 합성섬유는 내마모성, 내진동성을 더욱 강화하기 위해 상기 폴리에틸렌 섬유의 일부를 탄성섬유로 치환할 수 있다.In addition, in the synthetic fiber according to the present invention, part of the polyethylene fiber can be replaced with elastic fiber to further enhance wear resistance and vibration resistance.

상기 탄성섬유는 수분흡습성이 용이하여 이에 따른 기계적 물성 강화 효과를 얻을 수 있으며, 특히 신장율이 증가하기 때문에 내마모성 및 진동 억제 효과를 크게 상승시킬 수 있다.The elastic fiber has easy moisture absorption, so the effect of strengthening mechanical properties can be obtained. In particular, since the elongation rate increases, the wear resistance and vibration suppression effect can be greatly increased.

구체적으로 상기 탄성섬유는 폴리에테르 에스테르 엘라스토머로서, 하드 세그먼트의 원료인 에틸렌 글리콜과 부틸렌 글리콜을 디메틸 테레프탈레이트와 촉매하에서 에스테르화 반응을 진행한 후, 이 반응물에 금속염과 소프트 세그먼트의 원료인 폴리에틸렌 글리콜을 축중합하여 제조할 수 있다.Specifically, the elastic fiber is a polyether ester elastomer. After ethylene glycol and butylene glycol, which are the raw materials of the hard segment, are esterified with dimethyl terephthalate in the presence of a catalyst, metal salt and polyethylene glycol, which is the raw material of the soft segment, are added to this reactant. It can be manufactured by condensation polymerization.

이때 상기 반응물은 금속염으로 유기 술폰산 금속염을 공중합하는 것이 폴리에테르에스테르 엘라스토머의 고유점도를 용이하게 향상 시킬수 있으며, 또한 얻어지는 탄성 섬유의 흡습률 및 흡수신장률을 훨씬 높게 할 수 있다. 이러한 금속염으로 예를 들면 게르마늄 화합물, 안티몬 화합물, 티탄 화합물, 코발트 화합물, 주석 화합물을 포함할 수 있으며, 본 발명이 이에 제한되는 것은 아니다.At this time, copolymerizing an organic sulfonic acid metal salt with a metal salt as the reactant can easily improve the intrinsic viscosity of the polyether ester elastomer, and can also significantly increase the moisture absorption rate and absorption elongation rate of the obtained elastic fiber. Such metal salts may include, for example, germanium compounds, antimony compounds, titanium compounds, cobalt compounds, and tin compounds, but the present invention is not limited thereto.

상기 합성섬유는 전체 폴리에틸렌 섬유 100 중량% 중 30 내지 50 중량%를 폴리에테르에스테르 엘라스토머 섬유로 치환하는 것이 바람직하다. 치환되는 양이 상기 범위 미만인 경우 원단의 진동억제 효과가 미비하며, 상기 범위를 초과하여 첨가하는 경우, 원단의 신장율이 지나치게 증가하여 형태안정성, 차폐성이 하락할 수 있으며, 이에 따른 소음 차폐 효과가 떨어질 수 있다.It is preferable that 30 to 50% by weight of the synthetic fibers out of 100% by weight of the total polyethylene fibers are replaced with polyetherester elastomer fibers. If the amount of substitution is less than the above range, the vibration suppression effect of the fabric is insufficient, and if it is added in excess of the above range, the elongation of the fabric may increase excessively, which may reduce dimensional stability and shielding properties, and thus the noise shielding effect may be reduced. there is.

본 발명에서 상기 원단섬유는 섬도나 섬유장을 한정하지 않는다. 일예로 상기 원단섬유를 구성하는 천연섬유, 합성섬유 모두는 10 내지 100㎜인 것이 상기 범위에서 웹 형성 및 교락이 제대로 이루어져 바람직하다. 또한 섬도는 1 내지 100 데니어, 바람직하게는 10 내지 50 데니어인 것이 결속력을 유지하면서 카딩(carding) 시 원사 이송이 원활할 수 있어 좋다.In the present invention, the fineness or fiber length of the fabric fiber is not limited. For example, it is preferable that the natural fibers and synthetic fibers that make up the fabric fibers are 10 to 100 mm because web formation and entanglement are properly achieved within this range. In addition, a fineness of 1 to 100 denier, preferably 10 to 50 denier, is good because it maintains binding force and allows smooth transfer of yarn during carding.

본 발명에서 상기 a) 단계는 일반적인 니들펀칭을 위한 웹 제조방법과 동일한 방법을 적용할 수 있다. 예를 들어 먼저 천연섬유와 합성섬유 모두 표준상태(25℃±3, 상대습도 50 내지 60%)에서 24시간 내외로 보관하여 방적공정 중에 발생한 정전기를 제거한 후, 상기 섬유들을 혼섬하여 웹을 제조한다. In the present invention, step a) can be performed using the same method as the general web manufacturing method for needle punching. For example, first, both natural fibers and synthetic fibers are stored at standard conditions (25℃±3, relative humidity 50 to 60%) for about 24 hours to remove static electricity generated during the spinning process, and then the fibers are mixed to produce a web. .

상기 소면공정은 통상의 카딩 방법으로 제조할 수 있으며, 다만 상대습도는 표준상태에서 진행하는 것이 부유섬유 발생에 따른 웹의 불균질 증가를 방지할 수 있다. 상기 소면 공정을 통해 천연섬유와 합성섬유 모두 균일하게 혼합된 균일한 웹을 형성할 수 있다.The carding process can be manufactured by a normal carding method, but carrying out the relative humidity at a standard condition can prevent an increase in web heterogeneity due to the generation of floating fibers. Through the carding process, a uniform web in which both natural fibers and synthetic fibers are uniformly mixed can be formed.

본 발명에서 상기 b) 단계는 상기 원단섬유를 니들펀칭하여 펠트원단으로 제조하는 단계로, 상기 펠트원단은 니들펀칭법을 통해 제조할 수 있다.In the present invention, step b) is a step of manufacturing a felt fabric by needle punching the fabric fibers, and the felt fabric can be manufactured through a needle punching method.

상기 니들펀칭은 부직포를 제조하는 한 방법으로, 기본적으로 예비펀칭 및 메인펀칭의 2회에 걸쳐 실시하는 것이 좋다. 또한 상기 원단섬유는 한번에 원하는 수준의 기분 중량을 달성하기 어려우므로, 웹의 적층 방향을 바꾸어 여러번 적층하는 크로스랩핑법으로 제조하는 것이 바람직하다.The needle punching is a method of manufacturing non-woven fabric, and is basically recommended to be performed twice: preliminary punching and main punching. In addition, since it is difficult to achieve the desired level of weight at once, the fabric fiber is preferably manufactured by a cross-wrapping method in which the web is laminated several times by changing the lamination direction.

구체적으로 상기 웹은 섬유 배열이 수직 교차 또는 대칭 교차할 수 있도록 한다. 이는 여러 방향으로 균일한 특성을 부여하기 위한 것으로, 섬유층의 두께와의 조합으로 등방성을 향상시키기 위해 더욱 바람직하다.Specifically, the web allows the fiber arrays to intersect perpendicularly or symmetrically. This is to provide uniform properties in various directions, and is more desirable to improve isotropy in combination with the thickness of the fiber layer.

니들펀치는 상하왕복 운동을 하는 펀칭헤드에 고정되어 있는 다수의 니들이 가이드 평판을 통과하여 적층체 내부를 통과하여 실시된다. 이때, 적층체를 통과하는 니들의 상하운동에 의해 적층체 내부 섬유는 두께 방향으로 배열되어 이와 다른 배열의 섬유들과 엉키게 되면서 섬유층 내부에서 섬유들 사이에서와 동시에 섬유층간 결속이 강화된다. Needle punching is performed by passing a number of needles fixed to a punching head that moves up and down through a guide plate and inside the laminate. At this time, due to the vertical movement of the needle passing through the laminate, the fibers inside the laminate are arranged in the thickness direction and become entangled with fibers of other arrangements, thereby strengthening the bond between the fibers within the fiber layer and at the same time between the fiber layers.

상기 니들은 측면에 돌출된 바브(barb)가 있거나 니들의 끝부분이 갈라진 포크(fork)가 있는 형상이 바람직하나 반드시 이에 제한되는 것은 아니다. 바람직하게는 섬유의 직경이 작을수록 바브가 유리하고, 섬유의 직경이 클수록 포크가 유리하다. 니들의 측면에 돌출된 바브는 크기가 작아 직경이 큰 섬유는 바브에 걸려서 이송되기 어렵고, 니들의 끝부분이 갈라진 포크는 직경이 큰 섬유도 효과적으로 이송할 수 있으나, 직경이 작은 섬유에 포크를 적용 시 섬유 절단이 이루어지기 쉬우므로 섬유의 직경을 고려하여 니들 형상을 선택하는 것이 중요하다.The needle is preferably shaped to have a protruding barb on the side or a fork at the end of the needle, but is not necessarily limited thereto. Preferably, the smaller the fiber diameter, the more advantageous the barb is, and the larger the fiber diameter, the more advantageous the fork. The barb protruding from the side of the needle is small in size, so large-diameter fibers get caught on the barb and are difficult to transport. The fork with a split end of the needle can effectively transport large-diameter fibers, but the fork is applied to small-diameter fibers. It is important to select the needle shape considering the diameter of the fiber because it is easy to cut the fiber during operation.

본 발명에서 니들펀치 시 니들삽입깊이는, 니들이 섬유층과 만나는 지점으로부터 섬유층 내부로 삽입되는 총 깊이를 의미하는 것으로, 바람직하게는 10mm 내지 60mm일 수 있다. 니들삽입깊이가 10mm 미만인 경우, 니들삽입이 불충분하여 니들펀치 효과가 미미하여 층간 결속이 제대로 이루어지기 어려우며, 니들삽입깊이가 60mm 초과인 경우 니들이 섬유를 과도하게 깊이 끌고 들어감에 따라 섬유가 손상되거나 끊어지는 문제가 발생할 수 있다. In the present invention, the needle insertion depth during needle punching refers to the total depth inserted into the fiber layer from the point where the needle meets the fiber layer, and may preferably be 10 mm to 60 mm. If the needle insertion depth is less than 10 mm, the needle punch effect is minimal due to insufficient needle insertion, making it difficult to properly bind the layers, and if the needle insertion depth is more than 60 mm, the needle pulls the fiber excessively deep, causing damage or breakage of the fiber. Problems may arise.

또한, 니들펀치 시 펀치밀도를 조절할 수 있다. 상기 펀치밀도는 단위면적 당 펀치회수를 의미하는 것으로, 펀치밀도를 높여 적층체 내부에 두께방향의 섬유량을 늘릴 수 있으나, 과도한 섬유 손상이 있을 수 있어 펀치회수를 조절하는 것이 바람직하다. 상기 펀치밀도는 크게 제한되는 것은 아니지만, 10 내지 25 침투수/㎠이며, 보다 바람직하게는 15 내지 20 침투수/㎠인 것이 더욱 좋다. Additionally, the punch density can be adjusted when needle punching. The punch density refers to the number of punches per unit area. By increasing the punch density, the amount of fibers in the thickness direction inside the laminate can be increased, but excessive fiber damage may occur, so it is desirable to adjust the number of punches. The punch density is not greatly limited, but is 10 to 25 penetrations/cm2, and more preferably 15 to 20 penetrations/cm2.

또한, 펀칭헤드에 고정되어 있는 다수의 니들은 각 니들 사이의 간격이 일정한 것이 좋다. 바람직하게는 상기 니들 간격이 0.5mm 내지 20mm 사이인 것일 수 있다. 상기 범위를 벗어나면 섬유층이 쉽게 손상되거나 층간 결속 효과가 충분히 구현되지 않을 수 있다. In addition, it is better for the multiple needles fixed to the punching head to have constant spacing between each needle. Preferably, the needle spacing may be between 0.5 mm and 20 mm. If it is outside the above range, the fiber layer may be easily damaged or the interlayer binding effect may not be sufficiently realized.

다음으로 상기 c) 단계와 같이 상기 펠트원단을 재단 및 재봉하는 단계를 수행할 수 있다. 다만 상기와 같이 제조된 펠트원단을 재단, 재봉하기 전에 열처리를 먼저 진행하여 원단의 마찰력과 내구성을 더욱 높이도록 할 수 있다.Next, the step of cutting and sewing the felt fabric can be performed as in step c) above. However, before cutting and sewing the felt fabric manufactured as above, heat treatment can be performed first to further increase the friction and durability of the fabric.

상기 열처리는 100 내지 300℃로 가열된 롤러에 상기 펠트원단을 통과시켜 압축하는 공정으로, 이때 롤러는 하나 또는 두 개 모두 가열된 것일 수 있다. 특히 모든 롤러를 가열하여 원단의 양면 모두를 열처리하는 경우, 원단 표면에 발생할 수 있는 단섬유의 탈리를 방지할 수 있으며, 특히 합성섬유가 열에 의한 수축으로 인해 천연섬유를 잡아주기 때문에 니들펀칭에 의한 섬유간 교락이 더욱 공고해질 수 있다.The heat treatment is a process of compressing the felt fabric by passing it through rollers heated to 100 to 300° C. In this case, one or both rollers may be heated. In particular, when all rollers are heated and both sides of the fabric are heat treated, detachment of short fibers that may occur on the fabric surface can be prevented. In particular, since synthetic fibers hold natural fibers due to shrinkage by heat, needle punching The inter-fiber bridging may become more solidified.

상기와 같이 열처리하여 압축한 후에는 건조기 드럼에 적용하기 위한 폭을 갖도록 필요한 크기로 재단하고, 재단된 면을 재봉할 수 있다.After heat treatment and compression as described above, it can be cut to the required size to have a width for application to a dryer drum, and the cut side can be sewn.

상기 재단된 펠트섬유 원단은 열처리 된 표면 일측 가장자리 길이방향을 따라 신축밴드를 재봉하는데, 상기 신축밴드의 이면에는 신축밴드보호부재가 접착된 것을 사용하는게 바람직하다. 이는 상기 신축밴드의 재질이 신축성. 즉, 탄성력을 갖는 고무, 합성수지, 실리콘 중 어느 하나로 이루어질 수 있는데, 이러한 신축성을 가진 재질들은 내구성이 대부분 약하므로, 그 신축밴드에 견고함을 더해 주기 위함이다.The cut felt fiber fabric is sewn with an elastic band along the longitudinal direction of one edge of the heat-treated surface, and it is preferable to use an elastic band protection member attached to the back of the elastic band. This means that the material of the elastic band is elastic. In other words, it can be made of any one of elastic rubber, synthetic resin, and silicon. Since these elastic materials are mostly weak in durability, this is to add sturdiness to the elastic band.

또한, 상기 신축밴드의 이면에 신축밴드보호부재가 접착되지 않을 경우 신축밴드가 열을 받고 냉각되는 과정이 반복되면서 신축성이 저하됨은 물론이고 크랙(crack)의 발생 또는 절단되는 등의 문제점이 발생할 수 있으므로, 이를 방지하기 위해 신축밴드의 이면에는 신축밴드보호부재가 접착된 것을 사용하는게 바람직하다. 그리고, 상기 신축밴드보호부재는 구조의 특성상 내구성이 강한 망사형 섬유로 형성함이 바람직하다.In addition, if the elastic band protection member is not adhered to the back of the elastic band, the process of heating and cooling the elastic band is repeated, which not only reduces elasticity, but also causes problems such as cracks or cutting. Therefore, in order to prevent this, it is desirable to use an elastic band protection member attached to the back of the elastic band. In addition, the elastic band protection member is preferably formed of a highly durable mesh-type fiber due to the nature of the structure.

이때, 상기 신축밴드를 사용하는 이유는, 드럼의 실링부위. 즉, 드럼의 외주연을 감싸며 실링될 때에 펠트섬유 원단에 견고함을 부여함은 물론 신축밴드의 신축성으로 인해 드럼의 외주연 실링력을 향상시키기 위함이다. 한편, 상기 신축밴드를 재봉할 때에는 그 신축밴드의 양측 가장자리를 재봉함이 바람직하다.At this time, the reason for using the elastic band is the sealing part of the drum. In other words, it is intended to provide sturdiness to the felt fiber fabric when sealing by wrapping around the outer periphery of the drum, as well as to improve the sealing force around the outer periphery of the drum due to the elasticity of the elastic band. Meanwhile, when sewing the elastic band, it is preferable to sew both edges of the elastic band.

상기와 같이 펠트섬유 원단의 일측 표면 가장자리에 펠트섬유 원단의 길이방향을 따라 신축밴드가 재봉되면, 그 다음에는 상기 신축밴드가 재봉되지 않은 펠트섬유 원단의 타측 가장자리 일부를 펠트섬유 원단의 열처리가 되지 않은 이면 방향의 길이방향을 따라 접고 재봉하는데, 그 이유는, 펠트섬유 원단을 중첩시켜 재봉함으로써 펠트섬유 원단의 견고함을 증대시켜주고, 이와 아울러 드럼의 선/후단부와 면 접촉되는 건조기의 주변장치. 즉, 프론트 서포터 및 리어 서포터와의 면 접촉력을 향상시키기 위함이다.When an elastic band is sewn along the longitudinal direction of the felt fiber fabric on one surface edge of the felt fiber fabric as described above, then a part of the other edge of the felt fiber fabric on which the elastic band is not sewn is not subjected to heat treatment of the felt fiber fabric. It is folded and sewed along the longitudinal direction of the back side, which is not covered, and the reason is that the sturdiness of the felt fiber fabric is increased by overlapping and sewing, and in addition, the surrounding area of the dryer that is in contact with the front/rear end of the drum is used. Device. That is, the purpose is to improve the surface contact force with the front supporter and rear supporter.

상기와 같이 타측 가장자리를 접어 재봉되면, 그 재봉된 펠트섬유 원단을 드럼의 외경 길이와 준하는 길이를 갖도록 재단하고 그 재단된 펠트섬유 양단의 양 끝단을 상호 맞대기 접촉시킨 후, 그 접촉된 양 끝단을 상호 재봉하여 일체화시킨다.When the other edge is folded and sewn as described above, the sewn felt fiber fabric is cut to have a length similar to the length of the outer diameter of the drum, and both ends of the cut felt fiber are brought into contact with each other, and then both ends are brought into contact. They are sewn together and integrated.

상호 맞대기 접촉된 펠트섬유 원단의 양 끝단 재봉방법은, 일 구현예로서, 먼저 상기 가장자리를 접어 재봉한 재봉선의 연이어지는 방향으로 일정 폭 만큼 수회 반복하여 재봉하고, 그 후 맞대기 접촉선을 따라 지그재그 방향으로 재봉하는데, 상기 재봉선의 연이어지는 방향으로 일정 폭 만큼 수회 반복하여 재봉하는 이유는, 절단된 양 끝단의 재봉선이 풀릴 수 있음으로, 그 재봉선이 풀리는 것을 방지하기 위함이다.A method of sewing both ends of a felt fiber fabric in butt contact with each other is, as an embodiment, first folding the edges and sewing them repeatedly several times for a certain width in a continuous direction of the sewn sewing line, and then in a zigzag direction along the butt contact line. The reason why the sewing line is repeatedly sewn several times for a certain width in the direction in which the sewing line continues is to prevent the sewing line from unraveling because the sewing line at both cut ends may unravel.

또한, 상기 절단된 양 끝단을 맞대기 접촉시키고, 그 맞대기 접촉선을 따라 지그재그 방향으로 재봉하는 이유는, 재봉된 양 끝단이 단턱없이 평평하게 하기 위함이다. 가령, 상기 양 끝단에 단턱이 발생하면 그 단턱으로 인한 실링력이 저하되는 문제점이 발생할 수 있다.In addition, the reason why the cut ends are brought into butt contact and sewn in a zigzag direction along the butt contact line is to ensure that both sewn ends are flat without any unevenness. For example, if a step occurs at both ends, a problem may occur in which the sealing force is reduced due to the step.

상기 맞대기 접촉선을 따라 지그재그 방향으로 재봉이 완료되면, 그 다음에는 상기 신축밴드가 재봉된 가장자리를 열처리가 되지 않은 이면 방향으로 길이방향을 따라 접어 재봉하되, 그 재봉선에서부터 접은 가장자리 단부 까지를 드럼의 외경을 감싸는 연장부로 형성시킨다.When sewing is completed in the zigzag direction along the butt contact line, the edge where the elastic band is sewn is folded and sewn along the length direction in the direction of the non-heat treated back side, and the edge from the sewing line to the end of the folded edge is sewn on the drum. It is formed into an extension that surrounds the outer diameter.

상기 연장부를 형성시키는 이유는, 드럼의 외경을 견고히 감싸며 기밀성을 유지하도록 하기 위함이다. 다만, 상기 연장부의 내면과 드럼의 외경 간에는 접착제를 이용하여 접착 고정시키는게 바람직하다.The reason for forming the extension is to tightly surround the outer diameter of the drum and maintain airtightness. However, it is preferable to use adhesive to secure the inner surface of the extension portion to the outer diameter of the drum.

본 발명은 상기와 같은 제조방법으로부터 제조된 건조기용 진동방지 패드를 포함할 수 있다. 본 발명에 따른 제조방법으로 제조된 건조기용 진동방지 패드는 방적 후 폐기되는 천연섬유, 특히 양모에 합성섬유를 혼합하여 제조함으로써 마찰계수를 낮추고 마찰에 따른 마모를 감소시킬 수 있다. 또한 충분한 벌키성을 확보함으로써 진동과 이에 따른 소음을 크게 줄일 수 있다. The present invention may include an anti-vibration pad for a dryer manufactured using the above manufacturing method. The anti-vibration pad for a dryer manufactured by the manufacturing method according to the present invention can lower the coefficient of friction and reduce wear due to friction by mixing synthetic fibers with natural fibers, especially wool, which are discarded after spinning. Additionally, by ensuring sufficient bulkiness, vibration and resulting noise can be greatly reduced.

[표 2][Table 2]

상기 표 2와 같이 본 발명에 따라 제조된 패드는 양모 또는 폴리에틸렌 섬유로만 제조된 비교예에 비해 우수한 인장강도와 함께 내마모성 및 내진동성이 크게 상승한 것을 알 수 있다. 구체적으로 합성섬유로 엘라스토머 섬유를 더 포함한 실시예 2는 실시예 1에 비해 내진동성이 크게 상승하였으며, 여기에 바인더 및 탄성체를 천연섬유 표면에 적용한 실시예 3은 실시예 3에 비해 내진동성이 50% 상승한 것을 알 수 있다.As shown in Table 2 above, it can be seen that the pad manufactured according to the present invention has excellent tensile strength and significantly increased abrasion resistance and vibration resistance compared to the comparative example made only of wool or polyethylene fiber.
