본 발명은 2 종의 열가소성 합성섬유 멀티 필라멘트사의 신도차를 이용하여 방적사풍의 다층 구조사를 제조하는 방법에 관한 것으로, 특히 신도차를 이용하여 다층 구조사를 제조함과 동시에 불균일 연신의 특징을 부여하여 태세효과를 발현한 복합 가연사의 제조방법에 관한 것이다.The present invention relates to a method for producing a multi-layer structured yarn of spun yarn wind using two different types of thermoplastic synthetic fiber multifilament yarns, and in particular, to prepare a multi-layered structured yarn using a new-difference and at the same time to impart nonuniform stretching characteristics The present invention relates to a method for producing a composite false twisted yarn having an effect.

기존의 신도차가 40 % 이상인 2 종의 열가소성 합성섬유 멀티 필라멘트사를 사용하여 방적사풍의 2 층 구조사를 제조하는 방법은 일본 공개특허 소 54-10194호, 동 55-98932호, 동 57-25432호, 동 57-25433호, 미국 특허 4307565호 등에 소개되어 있다.The method of manufacturing a two-layered yarn of spun yarn wind using two types of thermoplastic synthetic fiber multifilament yarn having an existing elongation difference of 40% or more is disclosed in Japanese Patent Application Laid-Open Nos. 54-10194, 55-98932, 57-25432, 57-25433, US Patent 4307565 and the like.

상기한 특허들의 기술적 구성은 신도차가 상이한 복수본의 원사를 유체분사에 의해 합사하여 주기적인 교락을 부여한 후, 연신 가연을 행하게 되는데 이때 신도가 적은 사는 장력을 많이 받아 심사가 되고, 신도가 큰사는 심사외부에 S,Z 교호연을 형성하면서 외층구조를 형성하게 된다. 상기한 특허 방법에 의해 제조된 2 층 구조사는 천연 섬유와 유사한 벌키성 및 촉감을 가지게 되나 천연섬유 고유의 섬도 및 색상 불균일성은 나타내지 못한다.In the technical configuration of the above patents, a plurality of yarns having different elongation differences are spliced together by fluid spraying to give periodic entanglement, followed by drawing combusting. The outer layer structure is formed by forming S and Z alternating edges outside the screening. The two-layer structured yarn produced by the above-described patent method has a bulkyness and feel similar to that of natural fibers but does not exhibit the fineness and color nonuniformity inherent in natural fibers.

본 발명은 상기한 단점을 극복하기 위한 것으로, 동일 소재의 원사 신도차만을 이용하여 태세효과를 발현하는 방적사풍의 다층 구조 가공사를 제조하는 방법을 제공하는 것이다.The present invention is to overcome the above-mentioned disadvantages, to provide a method of manufacturing a multi-layer structured yarn of a yarn-like yarn expressing the posture effect using only yarn elongation of the same material.

본 발명은 공급되는 2 종 원사의 신도차가 150% 이상되고, 심층부에 위치할 원사의 신도가 120%~135% 인 원사를 이용하여 오버피트율 0.5%~1.5%의 조건하에 강한 공기압을 이용하여 인터레이스 하고, 160℃이하의 온도로 연신 가연하여 제조하는 것을 특징으로 하는 다층 구조 가공사의 제조방법이다.The present invention uses a strong air pressure under a condition of 0.5% to 1.5% overfit rate by using a yarn having an elongation difference of 150% or more, and an elongation of 120% to 135% of the yarn to be located in the deeper portion. A method of producing a multilayered structured yarn comprising interlacing and stretching and burning at a temperature of 160 ° C. or less.

이하 도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에서는 신도차가 150% 이상인 2 종의 멀티 필라멘트사를 복합 가연하는데 이때 심사로 위치할 멀티 필라멘트사 (1) 의 데니어는 외층부에 위치할 멀티 필라멘트사 (2) 의 데니어 보다 작아야 한다. 이는 방적사 풍의 효과를 내기 위한 사는 외층부에 위치할 멀티 필라멘트사 (2) 로, 심사로 구성되는 멀티 필라멘트사 (1) 를 완전히 감쌀 수 있어야 하기 때문이다.In the present invention, two or more multifilament yarns having an elongation difference of 150% or more are composite twisted, wherein the denier of the multifilament yarns 1 to be positioned by the screening should be smaller than the denier of the multifilament yarns 2 to be positioned on the outer layer. This is because the yarn for producing the yarn-like effect is a multifilament yarn 2 to be placed on the outer layer, and must be able to completely wrap the multifilament yarn 1 composed of the screening.

심사로 위치할 멀티 필라멘트사 (1) 와 외층부에 위치할 멀티 필라멘트사 (2) 는 제 1 피이트 로울러 (3) 에 의해 오버 피드율 0.5~1.5% 로 공급된다. 이때의 오버 피드율은 제 2 피이트 로울러 (5) 와의 속도비이다. 이때 인터레이스 노즐 (4) 에서 공급되는 강한 공기에 의해 교락이 형성되는데 이때의 교락수는 50~80개m 공기의 압력은 3~4 kg으로 설정해 주는 것이 좋다.The multifilament yarns 1 to be positioned in the screening and the multifilament yarns 2 to be placed in the outer layer portion are supplied by the first feed roller 3 at an overfeed rate of 0.5 to 1.5%. The overfeed rate at this time is a speed ratio with the 2nd feed roller 5. At this time, the entanglement is formed by the strong air supplied from the interlace nozzle (4), the number of entanglement at this time it is good to set the pressure of air 50 ~ 80 m 3 ~ 4 kg.

교락이 형성된 사는 제 2 피이트 로울러 (5) 에 의해서 히타 (6) 및 가연 유니트 (7) 로 공급되어 지는데 이때 연신 로울러 (8) 와의 연신비는 1.6~1.8 이내, 히타의 온도는 160℃ 이하로 해 주어야 한다.The entangled yarn is supplied to the heater 6 and the flammable unit 7 by the second feed roller 5, wherein the draw ratio with the stretching roller 8 is within 1.6 to 1.8 and the temperature of the heater is 160 ° C or lower. You must do it.

히타를 통과해 연신된 사는 가연 유니트 (7) 를 통과하여 크림프 (Crimp)가 형성되는데 이때의 연수는 2400 T/M 이상 되어야 한다.The yarn drawn through the heater is passed through the combustion unit (7) to form a crimp, at which time the soft water must be at least 2400 T / M.

이러한 공정을 마치면 멀티 필라멘트 (1) 사는 심사로, 멀티 필라멘트 (2) 사는 위층부에 위치하여 S,Z 교호연을 형성하게 되며, 외층부에 위치한 멀티 필라멘트 (2) 사는 심층부의 멀티 필라멘트 (1) 사를 감싸게 되는데 이때 저온도 불균일 연신이 형성되어 섬도 및 색상의 혼합이 발현되는 태세 효과를 나타내게 된다.After this process, the multifilament (1) yarn is screened, and the multifilament (2) yarn is located in the upper layer to form an S, Z alternating lead, and the multifilament (2) yarn in the outer layer is multi-filament (1). ) The low temperature non-uniform stretching is formed at this time, showing the posture effect that the mixture of fineness and color is expressed.

이러한 방법으로 제조된 다층구조 가공사는 외층부의 멀티 필라멘트 및 심부의 멀티 필라멘트가 불균일 연신되어 각각 태세효과를 나타냄으로 해서 천연 방적사의 섬도 및 자연스러운 불균일성을 발현하는 다층구조 가공사를 얻을 수 있게 된다.The multi-layer processed yarn manufactured in this way has a multi-filament of the outer layer portion and the multi-filament of the core portion unevenly stretched to show the posture effect, thereby obtaining a multi-layer processed yarn expressing the fineness and natural non-uniformity of natural spun yarn.
