쿠션재 제조방법{Cushioning pad method} [0001] Cushioning pad method [0002]

본 발명은 쿠션재 제조방법에 관한 것으로서 보다 상세하게는 단섬유가 수평상태로 적층되어 형성된 웹적층물을 조직변환장치 내부에서 개섬 시켜 적층 형태가 랜덤 형태로 변화시켜 두께와 밀도가 균등하게 형성되도록 함으로서 탄성력, 흡음력, 인장력이 향상되도록 한 쿠션재 제조방법에 관한 것이다.
The present invention relates to a cushioning material manufacturing method, and more particularly, to a method of manufacturing a cushioning material by making a web laminate formed by laminating short fibers in a horizontal state into a tissue transformer to change the lamination form to a random shape, Elasticity, sound absorption, and tensile strength of the cushioning material.

일반적으로 쿠션재는 주로 침대 매트리스 소재와 같은 침장용으로 사용되어 왔으나, 최근에는 유리면이나 암면 등과 같은 기존의 단열 및 흡음자재에 비하여 인체에 무해하고, 재활용이 가능한 환경친화적인 소재라는 특징이 있어 이들의 대체재로서 크게 각광받고 있다. Generally, the cushioning material has been mainly used for a bed such as a bed mattress material, but recently it is characterized as an environment-friendly material which is harmless to the human body and can be recycled compared with existing insulating and sound-absorbing materials such as glass surface and rock surface. As a substitute.

상기와 같은 쿠션재의 제조 방법으로 첨부도면 도 1a에 도시된 융점이 서로 다른 저융점 단섬유와 고융점 단섬유를 개섬수단(10)을 이용하여 새털 같은 원사로 개섬하고 개섬된 섬유를 일정한 두께와 폭을 갖는 카딩수단(20)을 이용하여 웹층을 형성한다.The low melting point staple fibers and the high melting point staple fibers having different melting points as shown in Fig. 1A are opened with the use of the opener 10 by the method of producing the cushioning material as described above, A carding means 20 having a width is used to form a web layer.

상기 카딩수단(20)에 의하여 형성된 웹을 이송벨트 상에 골고루 펼쳐지게 깔고 일정한 두께를 형성하도록 웹적층수단(30)을 이용하여 웹을 수회 적층하여 웹적층물을 형성시킨다.A web laminate is formed by laminating a plurality of webs by using the web laminating means (30) so that the web formed by the carding means (20) spreads evenly on the conveying belt and forms a constant thickness.

상기 웹적층수단(30)에 의하여 일정한 높이로 적층되어 형성된 웹적층물을 이송벨드로 이송하면서 가열/압착수단(40)을 경유시 웹적층물이 가열과 동시에 압착되어 일정한 두께 예컨데 300mm로 적층된 웹적층물을 50mm의 두께를 갖도록 형성하고 냉각시켜 고밀도를 갖는 일반적인 쿠션재를 제조한다.The web laminate is squeezed at the same time as heating while the web laminate is stacked at a predetermined height by the web laminating means 30 and is fed to the conveying belt while the heating / The web laminate is formed to have a thickness of 50 mm and cooled to produce a general cushioning material having high density.

이와 같이 일반적인 쿠션재는 카딩수단(20)에 의해 제조된 웹을 웹적층수단(30)에 의하여 여러 장의 웹을 적층한 후 가열/압착수단(40)에 의해 가열과 동시에 압착한 후 냉각수단(50)을 이용하여 냉각하는 순서에 의해 제조된 쿠션재를 살펴보면 첨부도면 도 1b에 도시된 바와 같이 카딩수단(20)에 의해 웹이 적층되어 이루어진 웹적층물을 확인할 수 있다.The common cushioning material is obtained by laminating a plurality of webs by the web laminating means 30 to the webs produced by the carding means 20, pressing them together with the heating and pressing means 40, The cushioning material manufactured by the procedure of cooling using the cushioning material 20 can be identified by the carding means 20 as shown in FIG.

상기와 같이 웹적층물을 형성시키기 위하여 단섬유를 일정한 폭을 갖도록 저장수단에 적층하게 되는데 이때 상기 적층되는 단섬유가 어느 일측으로 편중되어 적층되거나 또는 개섬 되어 적층 될 시 어느 한 곳에 뭉쳐져 적층 되어 배출되면 웹 형성시 밀도가 균일하게 형성되지 못하여 상기 웹적층물 형성시 전체적인 밀도 역시 균등하지 못하고, 어느 한 부분에 많은 양의 단섬유가 뭉치어져 조밀한 밀도를 형성하여 탄성력, 흡음력, 인장력 등을 저하시켜 품질을 극감 시키는 커다란 문제점이 있다.
In order to form the web laminate as described above, the short fibers are stacked on the storage means so as to have a constant width. In this case, when the laminated short fibers are stacked on one side and laminated, The density is not uniformly formed during the formation of the web, so that the overall density of the web laminate is not uniform during formation of the web, and a large amount of short fibers are bundled in one portion to form a dense density, thereby lowering the elasticity, sound absorption, So that there is a great problem that the quality is drastically reduced.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 2는 본 발명의 기술이 적용된 쿠션재 제조방법을 보여주는 공정도로서, 이에 따른 본 발명의 쿠션재 제조방법은 서로 뭉쳐진 단섬유의 덩어리를 풀기 위한 개섬수단을 이용하여 개섬단계(S100)를 수행한다. FIG. 2 is a process diagram showing a method of manufacturing a cushioning material to which the technology of the present invention is applied. In the method of manufacturing a cushioning material according to the present invention, the opening step S100 is performed using opening means for loosening the loops of the single- .

상기 개섬단계(S100)는 통상적으로 표면에 침봉이 다수 돌출된 롤러를 다단으로 설치한 것을 사용하며, 본 발명에서의 개섬수단은 개섬기 및 소면기를 포함한다. 이와 같이 개섬된 섬유를 두께와 폭을 형성하도록 리저버 탱크에 투입하여 얇은 웹형태로 배출하는 웹배출단계(S200)를 수행한다. In the opening step S100, a roller in which a large number of needle sticks are protruded on the surface is used in a multi-stage manner, and the opening means in the present invention includes a can opening and a small side. The web discharging step (S200) for discharging the open fiber into the reservoir tank to form a thickness and a width and discharging the thin web is performed.

상기 웹배출단계(S200)에서 배출되는 웹을 좌, 우로 이동시키면서 수평 방향이면서 다층으로 적층하여 두께를 형성시키는 웹적층단계(S300)를 수행한다. 상기 웹적층단계(S300)에 의해 적층된 웹적층물(P1)을 이송 및 밀도를 균일하게 하기 위해 개섬 시키는 조직변환단계(S400)을 수행한다. A web stacking step (S300) is performed in which the web discharged in the web discharging step (S200) is shifted left and right while being stacked in layers in a horizontal direction to form a thickness. The web laminate P1 stacked by the web lamination step S300 is subjected to a tissue transformation step S400 for making the webs and the density uniform.

상기 조직변환단계(S400)는 웹적층물(P1)의 밀도를 균등하게 하기 위해 소정의 간격으로 챔버 내부에 다수의 침봉이 형성된 개섬로울러가 서로 대향 되게 설치되어 있어 상기 개섬로울러 사이를 통과하는 웹적층물은 한번 더 개섬 되는 것이다.In order to equalize the densities of the web piles P1, the tissue transformation step S400 is carried out such that the webbing passes through the gap between the web rollers P1, The laminate is once again carded.

이를 좀더 구체적으로 설명하면 상기 웹적층물의 단섬유는 수평 상태로 조직변환장치에 공급되지만 상기한 조직변환장치에 의해 랜덤 형태로 적층물의 조직이 변화되면서 즉, 웹적층물이 풀어헤쳐 지면서 단섬유의 적층 형태가 변화되면서 적층물의 밀도가 균일하게 형성된다. To be more specific, the short fibers of the web laminate are supplied to the texture converting apparatus in a horizontal state, but the texture of the laminated material is changed in a random form by the texture converting apparatus described above. That is, as the web laminate is loosened, The density of the laminate is uniformly formed while the laminate shape is changed.

이와 같이 조직변환단계(S400)에 의해 개섬된 랜덤적층물(P2)은 도 3에 도시된 바와 같이 밀도가 균일하게 형성되어 이루어진다. 상기와 같이 조직변환단계(S400)에 의해 개섬된 랜덤적층물(P2)의 단섬유와 단섬유를 서로 연결결합되도록 열융착결합 시키도록 가열압착단계(S500)를 수행한다. As described above, the random laminate P2 opened by the tissue transformation step S400 is formed with uniform density as shown in Fig. The hot pressing step S500 is performed so that the short fibers and the short fibers of the opened random laminate P2 are thermally welded to each other so as to be connected to each other by the tissue transformation step S400.

이와 같이 랜덤적층물(P2)이 가열압착단계(S500)에 의해 성형 되며 이를 냉각시키는 냉각단계(S600)를 수행하여 쿠션재(1)로 이루어진다. Thus, the random laminate P2 is formed by the cushioning material 1 by performing the cooling step S600 in which the random laminate P2 is formed by the hot pressing step S500 and cooled.

이상 설명한 바와 같은 본 발명의 쿠션재는 웹을 다층으로 적층시켜 두께를 형성된 웹적층물로 배출되는 웹적층물을 개섬 시키면 도 3에 도시된 바와 같이 랜덤적층물로 조직이 변화되며 변화된 랜덤적층물의 조직 전체가 균일한 밀도로 분포되어 쿠션재의 전체가 탄성력, 흡음력, 인장력 균등하게 이루어지는 효과가 있다. As described above, the cushioning material of the present invention has a structure in which the web is laminated in multiple layers and the web laminate discharged through the web laminate having a thickness is opened, the structure is changed into a random laminate as shown in FIG. 3, And the whole is distributed with a uniform density, so that the entire cushioning material has the effect that the elasticity, the sound absorption power, and the tensile force are uniform.

상기 조직변환단계(S400)에 의해 형성된 랜덤적층물(P2)을 도 4에 도시된 바와 같이 상기 조직변환단계(S400)에 의해 배출되는 랜덤적층물(P2)의 형태를 유지함과 이송시키도록 이송로울러가 구비된 정렬단계(S420)가 더 포함하여 이루어진 것이 바람직하다. The random laminate P2 formed by the texture transformation step S400 is transferred to maintain and transfer the shape of the random laminate P2 discharged by the texture transformation step S400 as shown in FIG. And an aligning step S420 provided with a roller.

이상 설명한 바와 같은 본 발명의 쿠션재는 단섬유가 수평상태로 적층되어 이루어진 웹적층물을 조직변환장치 내부에서 개섬시켜 적층 형태를 랜덤 형태로 변화시켜 밀도가 균일하게 형성되어 이루어지는 효과가 있다.
As described above, the cushioning material of the present invention has the effect of uniformly forming densities by changing the lamination shape into a random shape by opening the web laminate in which short fibers are laminated in a horizontal state.
