[발명의 분야][Field of Invention]

본 발명은 신축 탄성 복합사의 제조방법에 관한 것이다. 보다 구체적으로 본 발명은 신축탄성사의 제조와 후가공에 의한 복합을 하는 현행의 2-단계공정을 방사공정 중에 방사 및 복합을 동시에 행함으로써 공정을 단축한 1-단계 신축 탄성 복합사의 제조방법에 관한 것이다.The present invention relates to a method for producing a stretch elastic composite yarn. More specifically, the present invention relates to a method for manufacturing a one-stage elastic elastic composite yarn in which the current two-stage process of manufacturing elastic elastic yarn and compounding by post processing is shortened by simultaneously spinning and compounding during the spinning process. .

[발명의 배경][Background of invention]

스판덱스(Spandex)를 통칭되는 폴리우레탄(Polyurethane)계의 탄성사 및 1990년대에 개발된 폴리에스트르(PET)계의 탄성사는 스트레치성을 강조하는 최근의 추세에 힘입어 그 용도가 계속 증가되고 있다. 그러나 스판덱스는 염색이 되지 않는 단점으로 단독으로는 사용이 불가능하다. 따라서 이는 PET, 나일론(Nylon)등의 합성섬유나 아세테이트(Acetate), 레이온(Rayon), 울(Wool)등의 천연섬유와 별도의 복합공정에서 복합하여 신축 탄성 복합사를 제조하는데 사용되고 있다. 스판덱스를 복합용 이펙트(effect)원사와 복합하는 공정으로는 일반적으로 커버링(covering)에 의한 공정이 보편화되어 있으며, I/L 노즐(Nozzle)을 사용한 별도의 복합공정에 의한 단순복합도 진행되고 있다. 이러한 방법에 의해 직물이나 편물로 상품화될 때 합성 및 천연섬유 등의 복합용 이펙트원사와 복합하는 별도의 공정 때문에 공정이 길어지고 이에 따라 제조원가가 올라가는 단점이 있다.Polyurethane-based elastic yarns, commonly referred to as spandex, and polyester-based elastic yarns, developed in the 1990s, are increasingly being used due to recent trends that emphasize stretchability. However, spandex is not dyed and cannot be used alone. Therefore, it is used to manufacture elastic elastic composite yarn by combining in a separate composite process with synthetic fibers such as PET, nylon (Nylon) or natural fibers such as acetate, rayon, wool. Generally, the process of covering spandex with compound effect yarn is common, and simple compounding by separate compound process using I / L nozzle is also progressing. . When the product is commercialized as a woven or knitted fabric by such a method, a process is lengthened due to a separate process of combining with a composite effect yarn such as synthetic and natural fibers, thereby increasing manufacturing costs.

따라서 본 발명자들은 복합용 이펙트원사를 후가공 공정에서 혼합하는 대신에 스판덱스의 방사공정 중에서 혼합시킴으로써 공정을 단축한 신축 탄성 복합사의 제조방법을 개발하기에 이른 것이다.Therefore, the present inventors have come to develop a method for producing a stretchable elastic composite yarn, which shortens the process by mixing in the spinning process of spandex instead of mixing the composite effect yarn in the post-processing process.

[발명의 목적][Purpose of invention]

본 발명의 목적은 신축 탄성 복합사의 제조와 후가공에서 복합을 하는 현행 2-단계공정을 방사공정 중에 방사 및 복합을 병행함으로써 공정을 1단계로 단축하여 100m/min 이하인 복합사(Intermingled yarn)의 제조속도를 방사속도인 900 m/min-1000m/min까지 올릴 수 있는 신축 탄성 복합사의 제조방법을 제공하기 위한 것이다.An object of the present invention is to produce a composite yarn (Intermingled yarn) of less than 100m / min by shortening the process to one step by spinning and compounding the current two-stage process of compounding in the production and post-processing elastic elastic composite yarn An object of the present invention is to provide a method for manufacturing a stretchable elastic composite yarn capable of increasing the speed to 900 m / min-1000 m / min.

[발명의 요약][Summary of invention]

본 발명에 따른 신축 탄성 복합사의 제조방법은 방사공정에서 오일링(Oiling)후에 고데트롤러1(E)과 고데트롤러2(G)사이에서 3배의 연신을 행하고 상기 연신공정 중에 고데트롤러1(E)과 고데트롤러2(G)사이에 설치된 사분가이드1(F1)을 통하여 복합용 이펙트원사(L)를 투입하는 단계로 이루어진다.In the manufacturing method of the elastic elastic composite yarn according to the present invention, the stretching process is performed three times between the GOD controller 1 (E) and the GOD controller 2 (G) after oiling in the spinning process, and the GOD controller 1 (E) during the stretching process. ) And the composite effect yarn (L) through the quadrant guide 1 (F1) installed between the high controller 2 (G).

상기 연신공정이 완료된 복합사는 고데트롤러1(E)과 고데트롤러4(I)를 통과하여 권취기(K)에 권취되면, 고데트롤러4(I) 통과한 후 I/L노즐(J)을 통과함으로써 스판덱스 원사와 복합용 이펙트원사가 교락된다.When the stretching process is completed, the composite yarn is passed through the gode controller 1 (E) and gode controller 4 (I) and wound around the winding machine (K), after passing through the gode controller 4 (I) and passes through the I / L nozzle (J) Thus, spandex yarn and composite effect yarn are entangled.

상기에서 사용되는 복합용 이펙트원사로는 PET, 나일론 등의 합성섬유나 아세테이트, 레이온, 울 등의 천연섬유가 있다.Composite effect yarns used above include synthetic fibers such as PET and nylon, and natural fibers such as acetate, rayon and wool.

이하 본 발명의 내용을 하기에 상세히 설명한다.Hereinafter, the content of the present invention will be described in detail.

[발명의 구체예에 대한 상세한 설명]Detailed Description of the Invention

본 발명에 따른 신축 탄성 복합사의 제조방법은 방사공정에서 오일링(Oiling)후에 고데트롤러1(E)과 고데트롤러2(G)사이에서 3배의 연신을 행하고, 상기 연신공정 중에 고데트롤러1(E)과 고데트롤러2(G) 사이에 설치된 사분가이드1(F1)을 통하여 복합용 이펙트원사(L)을 투입하는 단계로 이루어진다. 상기에서 사용되는 복합용 이펙트원사로는 PET, 나일론 등의 합성섬유나 아세테이트, 레이온, 울 등의 천연섬유가 있다.In the manufacturing method of the elastic elastic composite yarn according to the present invention, the stretching process is performed three times between the GOD controller 1 (E) and the GOD controller 2 (G) after the oiling in the spinning process, and the GOD controller 1 ( Through the quadrant guide 1 (F1) installed between the E) and the high controller 2 (G) is composed of the step of introducing the composite effect yarn (L). Composite effect yarns used above include synthetic fibers such as PET and nylon, and natural fibers such as acetate, rayon and wool.

제1도는 본 발명에 따른 신축 탄성 복합사를 제조하기 위한 방사기. 고데트롤러, I/S노즐 및 권취기의 시스템을 개략적으로 도시한 구성도이다.1 is a spinning machine for producing a stretch elastic composite yarn according to the present invention. A schematic diagram showing a system of a gode controller, an I / S nozzle and a winder.

본 발명에 의한 방사공정은 고데트롤러1(E)과 고데트롤러2(G)의 사이에 연신이력을 부여할 수 있도록 고데트롤러2(G)의 속도를 고데트롤러1(E)의 속도보다 3배로 빠르게 하여 고데트롤러1(E)과 고데트롤러2(G)사이의 연신비가 3이 되도록 한다. 고데트롤러3(H)과 고데트롤러4(I)의 속도는 기본적으로 고데트롤러2(G)와 동일하게 세팅하며 필요에 따라 언더 피드(under feed) 및 오버 피드(over feed)의 조절이 가능하다. 고데트롤러1(E)과 고데트롤러2(G)의 사이에 설치된 사분가이드(F1)를 통하여 복합에 사용할 다른종류의 복합용 이펙트원사(L)가 투입된다. 이렇게 투입된 복합사는 가이드를 거쳐 고데트롤러4(I)와 권취기(K) 사이에 설치된 I/L노즐(J)에 의해 교락을 부여받아 최종적인 복합사로 제조된다. 이때 고데트롤러3(H)과 고데트롤러4(I) 사이에 설치된 사분가이드2(F2)는 복합된 사가 인접되어 있는 사에 의해 사절되는 것을 방지하는 역할을 한다. 사분가이드2(F2)가 없는 경우에는 사도의 헌팅(Hunting)에 의한 사절이 빈번히 발생한다. 연신공정이 완료된 복합사는 고데트롤러1(E)과 고데트롤러4(I)를 통과하여 권취기(K)에 권취되면, 고데트롤러4(I) 통과한 후 I/L노즐(J)을 통과함으로써 스판덱스 원사와 복합용 이펙트원사가 교락된다.In the spinning process according to the present invention, the speed of the GD controller 2 (G) is three times the speed of the GD controller 1 (E) so that the stretching history can be imparted between the GD controller 1 (E) and the GD controller 2 (G). Speed it up so that the draw ratio between Gode Controller 1 (E) and Gode Controller 2 (G) is 3. The speed of the GODD controller 3 (H) and GODD controller 4 (I) is basically set the same as the GODD controller 2 (G), and the under feed and the over feed can be adjusted as necessary. . Another kind of composite effect yarn L to be used for compounding is introduced through the quadrant guide F1 provided between the high-detroler 1 (E) and the high-deleter 2 (G). The composite yarn thus added is entangled by an I / L nozzle (J) installed between the gode controller 4 (I) and the winding machine (K) through a guide and is manufactured as a final composite yarn. At this time, the quadrant guide 2 (F2) installed between the high-detro controller 3 (H) and the high-detro controller 4 (I) serves to prevent the composite yarn is cut by the adjacent yarn. In the absence of quadrant guide 2 (F2), trimming due to hunting of apostles occurs frequently. After the stretching process is completed, the composite yarn is wound around the winding machine (K) by passing through the gode controller 1 (E) and gode controller 4 (I), and then passes through the I / L nozzle (J) after passing through the gode controller 4 (I). Spandex yarns and composite effect yarns are entangled.

본 제조방법에 의한 신축 복합 탄성사의 제조시에는 고데트롤러1(E) 이전에 충분한 고화가 필요하다. 충분한 고화가 이루어지지 않은 상태에서 3배 연신이 이루어지면, 3배 연신 상태로 데니어 및 원사 물성이 고정되어 최종적으로 사용하고자 하는 복합사의 데니어가 달라지고 회복률이 저하되는등 원사물성이 저하된다. 연신공정이 완료된 복합사는 고데트롤러1(E)과 고데트롤러4(I)를 통과하여 권취기(K)에 권취되면, 고데트롤러4(I)를 통과한 후 I/L노즐(J)을 통과함으로써 스판덱스원사와 복합용 이펙트원사가 교락된다.In the production of the stretchable composite elastic yarn according to the present production method, sufficient solidification is required before the GODDELOTER 1 (E). When three times stretching is performed without sufficient solidification, the denier and yarn properties are fixed in the three times stretching state, so that the denier of the composite yarn to be finally used is changed and the recovery rate is lowered. After the stretching process is completed, the composite yarn is passed through the GOD controller 1 (E) and the GOD controller 4 (I), and then wound around the winding machine K, and then passes through the I / L nozzle J after passing the GOD controller 4 (I). Thus, spandex yarn and composite effect yarn are entangled.
