종래, 견면은 저융점 섬유와 고융점 섬유 및 융점이 서로 다른 폴리머가 시스코어형 또는 병렬형으로 복합된 섬유, 특히 단섬유를 일정한 비율로 혼합 및 개섬한 후, 소정의 두께를 갖는 웹으로 만들고, 얻어진 웹을 소정의 두께로 적층하고 가열, 융착한 다음, 냉각 프레스 롤러를 사용하여 두께조정 및 표면정리를 하여 제조하여 왔다. Conventionally, the plush is made of a web having a predetermined thickness after mixing and opening fibers having a low melting point fiber and a high melting point fiber and polymers having different melting points in a ciscore type or in parallel, in particular, a single fiber, The obtained web was laminated to a predetermined thickness, heated and fused, and then produced by adjusting the thickness and surface finishing using a cold press roller.

그러나, 종래의 견면제조방법은 특정 수준 이상의 고 밀도를 갖는 견면을 제조하는 것이 불가능하였다.
However, the conventional method of manufacturing a plush has not been possible to produce a plush having a high density above a certain level.

따라서, 본 발명은 고밀도의 견면을 제조할 수 새로운 방법을 제공하는 것을 기술적 과제로 한다.Therefore, it is a technical object of the present invention to provide a new method for producing a high-density plush.

이러한 본 발명의 목적은 저융점섬유와 고융점섬유가 혼합된 섬유, 또는 저융점 성분과 고융점 성분이 복합된 섬유를 개섬하여 웹으로 형성시키고, 형성된 웹을 적층한 후 이를 열처리하고, 가열압착하여 소망하는 두께의 견면을 제조하는 방법에 있어서, 상기 가열압착 공정이 저융점 섬유 또는 저융점 성분의 융점±20℃의 온도로 조절된 제 1 및 제 2 프레스롤 수단과 90±30℃의 온도로 조절된 제 3 프레스롤 수단에서 처리하는 것을 포함하는 것을 특징으로 하는 고밀도 견면의 제조방법에 의하여 달성된다.An object of the present invention is to form a web of the fibers mixed with a low melting point fiber and a high melting point fiber, or a fiber of a low melting point component and a high melting point component to form a web, laminating the formed web and then heat-treating it, and hot pressing In the method for producing a plush of a desired thickness, the hot pressing process is a temperature of 90 ± 30 ℃ and the first and second press roll means adjusted to a temperature of the melting point ± 20 ℃ of the low melting fiber or low melting component It is achieved by a method for producing a high density plush, characterized in that it comprises processing in a third press roll means adjusted to.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

첨부도면 도 1에 도시된 바와 같이 견면은 섬유가 개섬공정(10)에서 개섬되어 웹형성공정(20)에서 웹으로 형성시키고 적층공정(30)에서 웹을 소정의 두께로 적층시키고, 오븐과 같은 열처리수단을 통과시켜 열처리(40)한 후, 가열압착(50)하고, 소정의 크기로 절단하는 것에 의해 제조될 수 있다. As shown in Fig. 1, the plush fiber is opened in the opening step 10 to form a web in the web forming step 20, and the web is laminated in a lamination step 30 to a predetermined thickness, such as an oven. After the heat treatment means 40 through the heat treatment means, it can be produced by hot pressing 50, cut to a predetermined size.

본 발명에 있어서, 웹을 구성하는 섬유는 섬유의 융점차이를 이용하여 부직포를 제조하는데 사용되는 섬유로서 이러한 용도의 섬유는 당분야에 잘 알려져 있다. In the present invention, the fibers constituting the web are fibers used to make nonwoven fabrics using the melting point difference of the fibers, and fibers for such use are well known in the art.

이러한 섬유의 예로는 저융점 섬유와 고융점 섬유의 혼합섬유, 또는 융점이 서로 다른 폴리머가 시스코어형 또는 병렬형으로 복합된 섬유이다. 특히 바람직한 구성 섬유는 폴리에스테르계 섬유이다. Examples of such fibers are mixed fibers of low melting point fibers and high melting point fibers, or fibers in which polymers having different melting points are combined in a cis core type or in parallel. Particularly preferred component fibers are polyester fibers.                     

본 발명의 견면제조방법의 주된 특징은 가열압착공정에 있다. 본 발명에 의하면, 열처리된 웹적층물의 가열압착은 저융점 섬유 또는 저융점 성분의 융점±20℃의 온도로 조절된 2단의 프레스롤 수단과 90±30℃의 온도로 조절된 1단의 프레스롤 수단에서 처리하는 것을 포함한다. The main feature of the method of manufacturing a plush of the present invention is a heat compression process. According to the present invention, the heat compression of the heat-treated web laminate is a two-stage press roll means adjusted to a temperature of melting point ± 20 ° C. of low melting point fiber or low melting point component and a one-stage press controlled to a temperature of 90 ± 30 ° C. Processing in the roll means.

이와 같은 가열압착공정을 이용하게 되면 고밀도의 견면, 특히 두께가 20mm이하이고 밀도가 100㎏/㎥ 이상인 견면을 제조하는 것이 가능하게 된다. The use of such a hot pressing process makes it possible to produce a high density cotton, in particular, a thickness of 20 mm or less and a density of 100 kg / m 3 or more.

이러한 가열압착공정을 수행하기 위한 장치의 일예가 첨부도면 도 2에 도시된다. 도시되는 가열압착장치는 저융점 섬유 또는 저융점 성분의 융점±20℃의 온도로 조절된 제1 프레스롤 수단(51) 및 제2프레스롤 수단(52)과 그 후단에 설치되며 90±30℃의 온도로 조절된 제3 프레스롤 수단(53)이 일정간격으로 설치,구성된다. An example of an apparatus for carrying out such a hot pressing process is shown in FIG. 2. The illustrated hot pressing apparatus is installed at the first press roll means 51 and the second press roll means 52 and the rear end of the low melting point fiber or the low melting point component at a temperature of melting point ± 20 ° C, and is 90 ± 30 ° C. The third press roll means 53 adjusted to a temperature of is installed and configured at regular intervals.

이러한 프레스롤 수단들은 2개의 롤이 한조를 이루며, 하부 롤은 고정형이며 상부의 롤은 유동형으로 형성하는 것이 바람직하다.These press roll means are preferably two sets of rolls, the lower roll is fixed and the upper roll is formed in a fluid form.

열처리된 웹적층물을 가열압착하는데 있어서, 제1 및 제2 프레스롤 수단의 온도조건은 견면 또는 웹을 구성하는 저융점 섬유 또는 저융점 성분의 종류에 따라 다르게 적용되어야 하며, 바람직한 온도 조건은 저융점 섬유 또는 저융점 성분의 융점±20℃이다. In thermocompression bonding of the heat-treated web laminate, the temperature conditions of the first and second press roll means must be applied differently depending on the type of low melting fiber or low melting point component constituting the plush or web, and the preferred temperature conditions are low. Melting point The melting point of the fiber or low melting point component is ± 20 ° C.

예를 들어 구성섬유가 폴리에스테르계 혼합섬유 또는 복합섬유인 경우, 제1 및 제2 프레스롤 수단의 온도는 120℃∼160℃가 적당하다. For example, when the constituent fibers are polyester-based mixed fibers or composite fibers, the temperature of the first and second press roll means is suitably 120 ° C to 160 ° C.

저융점 섬유 또는 저융점 성분의 융점±20℃의 온도로 조절된 2단의 프레스 롤을 통과한 견면은 후단에 설치된 90±30℃의 온도를 갖는 1단의 프레스롤에 의해 고온으로 가열 압착된 견면이 상온으로 인출될 때 물성의 변화와 형태의 변화를 방지하기 위하여 서서히 냉각시키는 효과가 있다.The cotton wool passed through a two-stage press roll adjusted to a temperature of melting point ± 20 ° C. of low melting point fiber or low melting point component was heated and pressed at a high temperature by a one-stage press roll having a temperature of 90 ± 30 ° C. installed at the rear end. When the plush is drawn to room temperature, there is an effect of slowly cooling to prevent the change of physical properties and the change of shape.

특별히 한정하기 위한 것은 아니지만, 본 방법은 고밀도를 갖는 얇은 두께의 견면의 제조에 특히 바람직하다. 본 방법에 의하면 프레스롤 수단의 롤 사이의 간격을 조절하여, 두께가 20mm 이하이면서, 밀도가 100㎏/㎥ 이상, 바람직하게 100∼800㎏/㎥ 이상인 고밀도의 견면을 제조하는 것이 가능하게 된다. Although not particularly limited, the present method is particularly preferable for the production of a thin thickness dog face having a high density. According to this method, by adjusting the space | interval between the rolls of a press roll means, it becomes possible to manufacture the high-density cotton wool whose thickness is 20 mm or less, and whose density is 100 kg / m <3> or more, Preferably it is 100-800 kg / m <3> or more.

한편, 제3 프레스롤 수단은 롤 표면이 평활면 및/또는 소정 형상의 무늬가 조각된 조각면을 갖도록 할 수 있다. 제3 프레스롤 수단의 롤 표면을 조각면으로 형성하면 견면 표면에 용이하게 무늬를 새겨넣을 수 있어 효과적이다. On the other hand, the third press roll means may have a roll surface having a smooth surface and / or a engraving surface in which a pattern of a predetermined shape is carved. When the roll surface of the third press roll means is formed into a piece surface, the pattern can be easily engraved on the surface of the shoulder, which is effective.

본 방법에 있어서, 웹적층물은 열처리공정에서 처리하기 전에 저융점섬유 또는 저융점 성분의 융점 이하의 온도로 예열처리하면 이송되는 웹적층물이 흐트러지지 않고 웹과 웹이 원활하게 접착되는데 도움을 줄 수 있으므로 보다 균일한 품질의 견면을 제조하는 것이 가능하게 되어 바람직하다. 웹적층물의 예열처리는 저융점섬유 또는 저융점 성분의 융점 이하, 특히 바람직하게 60℃∼80℃의 온도에서 수행하는 것이 효과적이다.In this method, the web laminate is preheated to a temperature below the melting point of the low melting point fiber or the low melting point component before being treated in the heat treatment process to help the web laminate to adhere smoothly without being disturbed. Since it is possible to produce a more uniform quality cotton, it is preferable. The preheating of the web laminate is effective to be carried out at the melting point of the low melting point fiber or the low melting point component, particularly preferably at a temperature of 60 ° C to 80 ° C.

이상 설명한 바와 같이, 본 발명에 따라 열처리된 웹적층물을 3단으로 가열압착하면 고밀도를 갖는 얇은 두께의 견면, 특히 두께가 20mm 이하이면서, 밀도가 100㎏/㎥ 이상인 고밀도의 견면을 제조하는 것이 가능하게 된다. As described above, when heat-compression of the heat-treated web laminate according to the present invention in three stages, manufacturing a high-density plush having a high density, especially a high-density plush having a density of 20 kg or less and a density of 100 kg / m 3 or more It becomes possible.
