단열(Thermal insulation)의 주된 목적은 열손실이나 열취득을 억제하여 냉난방에 따른 에너지 소비량을 절약하기 위한 것으로서, 단열을 위한 재료로는 다양한 것이 있을 수 있으나, 그 중에서 공기층에 의한 단열효과는 매우 뛰어나다.The main purpose of thermal insulation is to save energy consumption by heating and cooling by suppressing heat loss and heat absorption. There are various materials for insulation, but the insulation effect by air layer is very excellent .

특히 오리, 닭, 거위 등의 깃털인 우모를 이용하여 단열재를 구성하게 될 경우에는 우모 내부에 포함되어 있는 공기에 의한 단열효과는 증대되게 된다.
Particularly, when a heat insulation material is formed using a feather of a feather, such as a duck, a chicken, or a goose, the heat insulation effect by the air contained in the heat insulation material is increased.

상기 우모를 적용하여 개시된 기술로는 대한민국등록특허 10-0918075(등록일자 2009년09월11일)의 '우모 직물과 그의 제조 방법 및 상기 우모 직물을 이용한 오일 처리 물품', 대한민국등록특허 10-0092613(등록일자 1995년09월14일)의 '우모포대', 대한민국등록특허 10-0302467(등록일자 2001년07월03일)의 '우모를 이용한 유흡착재의 제조방법 및 그로부터 생산된 유흡착재', 대한민국등록특허 10-0648190(등록일자 2006년11월14일)의 '우모 이불 및 그 제조방법' 및 대한민국등록특허 10-1032121(등록일자 2011년04월22일)의 '우모를 이용한 오일 흡착포 및 그 제조 방법' 등이 있으며, 이와 같이 개시된 기술들은 모두 우모와 직물 또는 부직포등이 직접적으로 얽히도록 하여 제조하는 것으로서, 이와 같은 방법을 이용하여 직물, 부직포 등을 사용하게 되는 경우에는 공기층의 부피가 현저하게 줄어들게 되어 단열효과가 급격히 떨어지게 되어 단열효과를 제대로 내기 어렵다는 문제를 갖고 있었다.Examples of the techniques disclosed by applying the above-described wool include Korean Patent No. 10-0918075 (filed on September 11, 2009), "Umo Textile, Method for Manufacturing the same, and Oil Treatment Product Using the Umo Fabric", Korean Patent No. 10-0092613 (Date of Registration: Sep. 14, 1995), Korean Patent No. 10-0302467 (filed on July 03, 2001), and a method of manufacturing a sorbent material using the same, and a sorbent material produced therefrom, Korean Patent Registration No. 10-0648190 (registered on November 14, 2006) and the Korean Patent No. 10-1032121 (registered on April 22, 2011) And a method of producing the same. The techniques disclosed above are all produced by entanglement of wool, a fabric or a nonwoven fabric directly.

상기 우모 부직포를 제조하기 위한 기술 구성으로서,As a technical configuration for manufacturing the wool nonwoven fabric,

폴리에틸렌 또는 폴리프로필렌 수지 80~99wt%와, 에틸렌-비스(테트라브로모프탈이미드), 테트라브로모 비스페놀 A, 디브로모크레실에테르, 트리브로모페놀, 트리브로모페닐 트리아진, 트리브로모페닐아릴에테르, 퍼클로로시클로데칸, 퍼클로로시클로펜타데칸 중 선택되는 어느 1종 또는 2종 이상의 난연제 1~20wt%의 혼합으로 조성된 혼합물을 1.5in 압출기에 도입하여 290℃의 방사노즐을 통해 방사하되, 방사속도 1,500 m/min로 방사한 섬도 2.2 denier의 단섬유를 이용하여 시트형의 부직포를 제조하는 단계와,80 to 99 wt% of polyethylene or polypropylene resin, ethylene-bis (tetrabromophthalimide), tetrabromo bisphenol A, dibromocresyl ether, tribromophenol, tribromophenyl triazine, tribro Mixture composed of a mixture of any one or two or more flame retardants selected from phenyl aryl ether, perchlorocyclodecane, perchlorocyclopentadecane 1 to 20wt% was introduced into a 1.5in extruder, Spinning, but manufacturing a sheet-like nonwoven fabric using short fibers of fineness 2.2 denier spun at a spinning speed of 1,500 m / min,

상기 시트형 부직포의 테두리를 따라 박음질을 통해 메쉬망과 부직포를 연결하는 단계와,Connecting the mesh net and the nonwoven fabric through a stitched along the edge of the sheet-shaped nonwoven fabric;

우모를 채운 부직포의 개방된 일측을 테두리를 따라 박음질하는 단계를 포함하여 이루어지는 우모 부직포 제조방법을 주요 기술적 구성으로 한다.
The main non-woven fabric manufacturing method comprising the step of stitching the open side of the nonwoven fabric filled with the feather along the rim as a main technical configuration.

본 발명에 따른 부직포는 우모를 사용하여 부직포를 제조하되, 기존의 방식과 달리 부직포 내부의 공기층을 충분히 확보하여 단열효과를 극대화시킴으로써 단열효과를 극대화시키고, 이에 따른 에너지 절감효과를 갖는다.
The nonwoven fabric according to the present invention is manufactured using non-woven fabric, but unlike the conventional method, the air layer inside the nonwoven fabric is sufficiently secured to maximize the insulation effect, thereby maximizing the insulation effect, and thus has an energy saving effect.

도 2는 본 발명에 따른 부직포의 구조를 보인 단면도.
도 3은 본 발명의 부직포를 구성하고 있는 메쉬망의 구조를 보인 사시도.1 is a cross-sectional view showing a conventional nonwoven structure.
Figure 2 is a cross-sectional view showing the structure of a nonwoven fabric according to the present invention.
Figure 3 is a perspective view showing the structure of a mesh network constituting the nonwoven fabric of the present invention.

이하, 상기의 기술 구성에 대한 구체적인 내용을 도면과 함께 살펴보고자 한다.Hereinafter, a detailed description of the technical configuration will be described with reference to the accompanying drawings.

도 1에 도시된 바와 같이, 본 발명에서 개선하고자 하는 부직포의 구조를 살펴보면, 우모층을 사이에 두고 상,하로 부직포층을 구성하여 샌드위치 구조를 이루어 우모와 부직포의 엉킴을 수행하여 최종적으로 우모를 포함하고 있는 부직포를 구성하게 되나, 앞서 살펴본 바와 같이, 이와 같은 구조의 부직포를 사용하게 되는 경우에는 부직포 내부에 포함되어 있는 우모 내의 공기층의 충분히 활용하기 어려울 뿐만 아니라, 공기층의 부피가 현저히 줄어들게 되어 공기층에 의한 단열효과를 극대화시키기 어렵다.
As shown in Figure 1, looking at the structure of the nonwoven fabric to be improved in the present invention, by forming a sandwich structure by forming a nonwoven layer up and down with a feather layer interposed between the feather and the nonwoven fabric to finally entangle the feather As described above, when the nonwoven fabric having such a structure is used, it is difficult to fully utilize the air layer in the wool contained in the nonwoven fabric, and the volume of the air layer is significantly reduced. It is difficult to maximize the insulation effect.

도 2는 상기 도 1에서 보인 부직포의 구조를 개선한 것을 보인 것으로서, 도 1에 도시된 것과 달리 메쉬망(30)을 더 포함하여 우모 부직포(1)를 구성한다.2 shows that the structure of the nonwoven fabric shown in FIG. 1 is improved, and unlike FIG. 1, the nonwoven fabric 1 further includes a mesh network 30.

즉, 상기 우모 부직포(1)는 우모(10)와,That is, the feather nonwoven fabric (1) is a feather (10),

상기 우모를 사이에 두어 샌드위치 구조를 이루는 부직포(20)와,Nonwoven fabric 20 to form a sandwich structure between the feathers,

상기 우모(10)와 부직포(20) 사이에 놓이는 메쉬망(30)을 포함하여 이루어진다.
It comprises a mesh net 30 which is placed between the feather 10 and the nonwoven fabric 20.

상기 부직포(20)는 난연특성을 부여하여 보온효과에 기능성을 더욱 보완한 것으로서, 부직포에 의한 화재위험성을 최소화할 수 있도록 한다.The nonwoven fabric 20 provides flame retardant properties to further complement the thermal insulation effect, thereby minimizing the risk of fire caused by the nonwoven fabric.

즉, 상기 부직포(20)는 폴리에틸렌 또는 폴리프로필렌 수지 80~99wt%와,That is, the nonwoven fabric 20 is 80 to 99wt% polyethylene or polypropylene resin,

에틸렌-비스(테트라브로모프탈이미드), 테트라브로모 비스페놀 A, 디브로모크레실에테르, 트리브로모페놀, 트리브로모페닐 트리아진, 트리브로모페닐아릴에테르, 퍼클로로시클로데칸, 퍼클로로시클로펜타데칸 중 선택되는 어느 1종 또는 2종 이상의 난연제 1~20wt%의 혼합으로 조성된 혼합물을 1.5in 압출기에 도입하여 290℃의 방사노즐을 통해 방사하되, 방사속도 1,500 m/min로 방사한 섬도 2.2 denier의 단섬유를 이용하여 부직포를 제조함으로써 부직포에 난연성을 부여할 수 있다.Ethylene-bis (tetrabromophthalimide), tetrabromo bisphenol A, dibromocresyl ether, tribromophenol, tribromophenyl triazine, tribromophenylaryl ether, perchlorocyclodecane, per A mixture of 1 to 20 wt% of any one or two or more flame retardants selected from chlorocyclopentadecan is introduced into a 1.5-inch extruder and spun through a spinning nozzle at 290 ° C., with a spinning speed of 1,500 m / min. One can also impart flame retardancy to nonwovens by making nonwovens from 2.2 denier short fibers.

상기 난연제의 사용량은 난연성의 특성을 최대한 유지하되, 부직포의 품질 특성을 저해하지 않는 범위 내에서 투입하는 것으로서, 그 사용량이 1wt% 미만인 경우에는 부직포의 난연 특성이 미미하여 난연 효과를 기대하기 어렵고, 20wt%를 초과하게 되는 경우에는 단섬유의 인장신율 등의 특성이 떨어져 상기 단섬유를 이용한 부직포의 제조가 용이하지 않을 수 있으므로, 상기 난연제의 사용량은 1~20wt%의 범위 내로 한정하는 것이 바람직하다.
The amount of the flame retardant to be used is kept within a range that does not impair the quality characteristics of the nonwoven fabric while maintaining the flame retardancy as much as possible. When the amount is less than 1 wt%, the flame retardancy of the nonwoven fabric is insignificant, %, The properties such as tensile elongation of the staple fibers may deteriorate and the production of the nonwoven fabric using the staple fibers may not be easy. Therefore, the use amount of the flame retardant is preferably limited to a range of 1 to 20 wt%.

본 발명에 따른 우모 부직포는 부직포 내의 공기층이 충분히 확보될 수 있도록 하기 위하여 메쉬망(30)을 넣어 부직포를 구성함에 특징이 있는 것으로서, 상기 메쉬망(30)는 도 3에 도시된 바와 같이 수지 망사(301)에 의한 그물 구조를 이룸과 동시에 상기 수지 망사가 상호 교차하는 교차점에는 부직포(20)와 우모(10)가 서로 일정한 간격을 유지할 수 있도록 수직방향의 상,하로 돌출 형성되어 있는 간격유지부재(302)를 구비하고 있다.
The feather nonwoven fabric according to the present invention is characterized in that the mesh net 30 is put in a nonwoven fabric so that the air layer in the nonwoven fabric is sufficiently secured, and the mesh net 30 is a resin mesh as shown in FIG. 3. At the same time that the resin mesh meshes with each other at the same time, the nonwoven fabric 20 and the feather 10 are formed to protrude upward and downward in the vertical direction so as to maintain a constant distance from each other. 302 is provided.
