본 발명은 스트레오-컴플렉스(Stereo-complex) 결정 구조를 갖는 고내열성 폴리락타이드(이하 "SC-PLA" 라고 한다)로 구성된 해도형 복합섬유(이하 "SC-PLA 해도형 복합섬유" 라고 한다)를 이용하여 생분해성으로 친환경적임과 동시에 내열성이 우수하고 공기투과도가 낮고, 강력, 내구성, 보온성 및 터치감 등이 양호한 다중직 텍스타일의 제조방법에 관한 것이다.The present invention relates to a sea-island type composite fiber (hereinafter referred to as "SC-PLA sea-island type composite fiber") composed of high heat-resistant polylactide (hereinafter referred to as "SC-PLA") having a stereo-complex crystal structure. It relates to a method of manufacturing a multi-woven textile that is biodegradable, eco-friendly, has excellent heat resistance, low air permeability, and has good strength, durability, warmth and touch.

다운자켓, 텐트, 침낭 및 가방(백팩) 제조용 원단의 경우에는 다운 충진제가 밖으로 빠져나오는 것을 효과적으로 방지할 수 있는 고밀도와 함께 우수한 강력 및 내구성과 양호한 보온성, 터치감 및 심색성이 동시에 요구되고 있다.In the case of down jackets, tents, sleeping bags, and bags (backpacks) manufacturing, high density that can effectively prevent down fillers from leaking out, as well as excellent strength and durability, good heat retention, touch and deep color are required at the same time.

다운자켓을 제조하는 종래기술로서, 대한민국 등록특허 제10-0915959호에서는 겉감과 안감 사이에 다운이 투입된 부분판들을 연결하여 다운자켓을 제조할 때, 부분판을 형성하는 겉감과 안감 사이에 고밀도 원단 테이프를 위치시킨 후 상기 겉감과 안감을 함께 봉제하여 다운 격실을 형성하는 방법을 게재하고 있으나, 상기 종래기술은 다운 충진제가 외부로 빠져나오는 것을 방지하기 위한 제조공정이 복잡한 문제가 있었다.As a prior art for manufacturing a down jacket, Korean Patent Registration No. 10-0915959 discloses a high-density fabric between the outer and lining forming a partial plate when manufacturing a down jacket by connecting partial plates to which down is inserted between the outer and lining. Although a method of forming a down compartment by sewing together the outer and inner linings after positioning the tape is disclosed, the prior art has a complicated manufacturing process for preventing the down filler from escaping to the outside.

다운자켓을 제조하는 또 다른 종래기술로서, 대한민국 공개특허 제10-2012-0032528호에서는 직물 상에 수지가 01~5g/㎡의 도포량으로 코팅되어 있는 박막코팅 직물을 사용하여 다운 충진제가 외부로 빠져나오는 것을 방지하는 방법이 게재되어 있으나, 상기 종래기술은 코팅원단 사용으로 터치감이 저하되는 문제가 있었다.As another prior art for manufacturing a down jacket, in Korean Patent Application Laid-Open No. 10-2012-0032528, a thin-film coated fabric in which a resin is coated on the fabric at an application amount of 01 to 5 g/m 2 is used, and the down filler is leaked out. Although a method for preventing it from coming out is disclosed, the prior art has a problem in that the touch feeling is lowered by using a coated fabric.

한편, 이중직 원단에 대한 종래기술로서, 대한민국 등록특허 제10-0317115호에서는 경사 및 위사가 폴리에스터 멀티필라멘트 표리 양면 지조직과 비스코스 인견 멀티필라멘트의 파일로 구성되어 번 아웃트 벨벳과 같은 효과를 갖는 파일 이중직의 편물을 하고 있고, 대한민국 등록특허 제10-1566634호에서는 온도 적응성이 우수한 이중직 환편물을 게재하고 있으나, 상기의 이중직 편물 또는 이중직 환편물은 밀도가 낮아 다운 자켓 제조용 직물로 사용시 다운 충진제가 외부로 쉽게 빠져 나가는 문제와 강도 및 내구성이 떨어지고, 터치감 및 심색성도 불량한 문제가 있었다.On the other hand, as a prior art for a double weave fabric, in Korean Patent Registration No. 10-0317115, the warp and weft yarns are composed of polyester multifilament front and back both sides paper tissue and viscose pull multifilament pile, which has the same effect as burnout velvet. A pile double weave is knitted, and Korean Patent No. 10-1566634 discloses a double weave circular knitted fabric with excellent temperature adaptability, but the double weave knitted or double weave circular knitted fabric has a low density, so when used as a fabric for manufacturing down jackets, down filler is There was a problem of easily escaping to the outside, poor strength and durability, and poor touch and deep color.

한편, 대한민국 등록특허 제10-2053234호에서는 다단연신된 가염성 폴리에스테르 멀티필라멘트를 경사 및/또는 위사로 사용하여 다중직 텍스타일을 제조하는 방법을 게재하고 있으나, 상기 방법으로 제조한 다중직 텍스타일은 기존의 종래 다중직 텍스타일들과 같이 생분해되지 않아 친환경적이지 못한 문제가 있었다.On the other hand, Korean Patent Registration No. 10-2053234 discloses a method of manufacturing a multi-woven textile using multi-stage stretched dyeable polyester multifilaments as warp and/or weft yarns, but the multi-woven textile manufactured by the method is There was a problem that it was not eco-friendly because it was not biodegradable like the conventional multi-woven textiles.

한편, 생분해성인 통상의 폴리락타이드 원사로 다중 텍스타일을 제조하는 방법도 일부 시도되어 왔으나, 통상의 폴리락타이드 원사의 용융온도가 낮기 때문에 제조된 다중 텍스타일의 내열성이 크게 저하되는 문제가 있었다.On the other hand, some methods for producing multi-textiles from biodegradable conventional polylactide yarns have been tried, but there is a problem in that the heat resistance of the multi-textiles produced is greatly reduced because the melting temperature of the conventional polylactide yarns is low.

본 발명의 과제는 생분해성을 구비하여 친환경적임과 동시에 내열성도 우수하고, 공기투과도가 낮아 다운자켓 제조용 원단 등으로 사용시 다운 충진제가 빠져나오는 현상을 효과적으로 방지할 수 있고, 양호한 보온성, 터치감, 강력 및 내구성을 구현할 수 있는 다중직 텍스타일을 제조하는 방법을 제공하는 것이다.The object of the present invention is to have biodegradability, so it is environmentally friendly and has excellent heat resistance, and its low air permeability can effectively prevent the down filler from leaking out when used as a fabric for down jacket manufacturing.

구체적으로, 본 발명은 먼저 (ⅰ) 폴리-L-락틱 애시드(Poly-L-lactic acid : PLLA) 및 폴리-DL-락틱 애시드(Poly-DL-lactic acid : PDLA)중에서 선택된 1종의 폴리머를 해도형 복합섬유 방사용 구금의 도성분 형성부(1)에 공급하고, 나머지 1종의 폴리머를 해도형 복합섬유 방사용 구금의 해성분 형성부(2)에 공급하여 상기 폴리-L-락틱 애시드(PLLA)와 폴리-DL-락틱 애시드(PDLA)를 서로 분리된 상태로 열처리하면서 복합방사하여 스트레오-컴플렉스(Stereo-complex) 결정 구조를 갖는 고내열성 폴리락타이드 해도형 복합섬유를 제조한다.Specifically, the present invention provides first (i) one polymer selected from poly-L-lactic acid (PLLA) and poly-DL-lactic acid (PDLA). The poly-L-lactic acid is supplied to the island component forming unit (1) of the spinneret for spinning a sea-island type composite fiber, and the remaining one type of polymer is supplied to the sea component forming unit (2) of the spinneret for spinning a sea-island type composite fiber. (PLLA) and poly-DL-lactic acid (PDLA) are heat-treated while separated from each other and composite spinning to prepare a high heat-resistant polylactide sea-island composite fiber having a stereo-complex crystal structure.

이때, 상기 고내열성 폴리락타이드 해도형 복합섬유를 구성하는 폴리-L-락틱 애시드(PLLA) 분자와 폴리-DL-락틱 애시드(PDLA) 분자간의 거리가 폴리-L-락틱 애시드(PLLA)의 결정 사이즈 및 폴리-DL-락틱 애시드(PDLA)의 결정 사이즈 보다 작게 조절해 준다.At this time, the distance between the poly-L-lactic acid (PLLA) molecules and the poly-DL-lactic acid (PDLA) molecules constituting the high heat-resistant polylactide sea-island composite fiber is determined by determining the poly-L-lactic acid (PLLA).
