2이상의 실을 합사방식을 통한 복합사는 합성섬유가 가지고 있는 장점과 방적사가 갖고 있는 장점을 하나의 실에 결집시키고자 하는 광범위한 노력으로 개발되어 왔다.Composite yarns of two or more yarns have been developed with a wide range of efforts to combine the advantages of synthetic fibers and the advantages of spinning yarns into one yarn.
종래에는 단순히 합성섬유의 필라멘트와 천연섬유의 방적사를 가연하는 형태의 합사방법으로 복합사를 제조하였으나, 점차 합사기술의 발달과 소비자의 다양한 욕구를 충족하기 위해 많은 사가공 기술이 개발되었다.Conventionally, a composite yarn was manufactured by simply folding filaments of synthetic fibers and spun yarns of natural fibers. However, many yarn fabrication techniques have been developed to meet the needs of the consumer and the development of folding technology.
특히 폴리에스테르 복합사는 폴리에스테르의 기본적인 우수한 물성에 다양한 기능을 추가할 수 있는 폴리에스테르 복합사가 많이 개발되고 있다.In particular, polyester composite yarns have been developed in many polyester composite yarns capable of adding various functions to the basic excellent physical properties of the polyester.

However, the above method has excellent bulkiness and touchability, but can not expect a natural feel or color development due to the use of synthetic fibers.
더욱이, 종래의 폴리에스테르 복합사는 벌키한 특성은 발현가능하나, 흡수성이 미흡하고 천연섬유와 같은 느낌의 폴리에스테르 복합사에 대해서는 개발이 미흡한 실정이다.Furthermore, conventional polyester composite yarns can exhibit bulky characteristics, but have insufficient water absorbability and are insufficient in development for polyester composite yarns that have the same feel as natural fibers.

상기 사공급단계는 폴리트리메틸렌테레프탈레이트(PTT)와 폴리에틸렌테레프탈레이트(PET)로 형성된 사이드 바이 사이드형의 부분연신사를 심사로, 이형단면의 폴리에스테르 부분연신사를 효과사로 공급단계로 상기 심사와 효과사는 각각의 사를 미리 권취롤러에 준비하여 공급할 수 있다.The yarn supplying step is a step of inserting a side-by-side type partially drawn yarn made of polytrimethylene terephthalate (PTT) and polyethylene terephthalate (PET) And the effect yarns can be prepared and supplied to the winding rollers in advance.
또는, 상기 사공급단계 전에 상기 심사와 효과사를 각각 방사하는 방사단계를 더 포함하여 심사와 효과사를 제조와 동시에 공급하여 본 발명의 폴리에스테르 복합사를 제조할 수 있을 것이다.Alternatively, the polyester composite yarn of the present invention may be manufactured by further including a spinning step of spinning the yarn before the yarn supplying step and the yarn yarn before the yarn supplying step, respectively.

본 발명에서 사용되는 폴리트리메틸렌테레프탈레이트(PTT)와 폴리에틸렌테레프탈레이트(PET)로 형성된 사이드 바이 사이드형의 심사는 폴리우레탄사를 제외하고 합성섬유 중에서 가장 신축성이 우수한 섬유로 심사로 사용되어 복합사의 신축성을 향상시키는 역할을 수행한다.The side-by-side type examination of polytrimethylene terephthalate (PTT) and polyethylene terephthalate (PET) used in the present invention is the most flexible fiber among the synthetic fibers except polyurethane yarns, Thereby improving the elasticity.
상기 폴리트리메틸렌테레프탈레이트(PTT)와 폴리에틸렌테레프탈레이트(PET)로 형성된 사이드 바이 사이드형의 심사는 신축성이 20%이상인 것이 바람직하며, 신축성이 30%이상인 것이 가장 바람직할 것이다.The screening of the side-by-side type formed of PTT and polyethylene terephthalate (PTT) preferably has a stretchability of 20% or more and a stretchability of 30% or more.
또한, 본 발명에서 사용되는 이형단면의 폴리에스테르 부분연신사의 효과사는 실이나 원단으로 형성시에 무수한 기공을 발생시켜 수분을 모세관 현상으로 통해 흡수할 수 있는 기능을 부여한다.In addition, the effect yarn of the polyester partially stretched yarn having the modified cross-section used in the present invention gives a function of generating innumerable pores when forming the yarn or fabric and absorbing moisture through capillary phenomenon.
상기 이형단면의 폴리에스테르 부분연신사는 십자형 단면, 삼엽 단면, 5엽단면, 4엽 단면 등 원단으로 형성시 기공을 형성시킬 수 있는 이형단면이면 어느 것이나 가능하나, 십자형 단면인 것이 가장 바람직할 것이다.The polyester partially drawn portion of the above-mentioned modified cross-section may be any of cross-sectional shapes capable of forming pores when formed into a fabric such as a cross-sectional shape, a trilobal shape, a 5-shape cross-section and a 4-shape cross-section.
상기 합사단계는 상기 심사와 효과사를 공기 교락을 통해 합사하는 단계로 일반적인 공기 교락장치를 통해 상기 심사와 효과사를 합사하여 복합사로 제조할 수 있다.The yarn mixing step is a step of folding the yarn yarn and the yarn yarn through air entanglement, and the yarn yarn and the yarn yarn are folded through a general air entanglement device to produce a composite yarn.
상기 연신가연단계는 합사된 복합사를 150~180℃에서 연신하면서 가연하는 단계로 합사된 복합사는 연신비는 1.5~2.0로 연신되는 것이 바람직한 것으로 고온에서 연신되어 결정화도가 향상되고 물성이 향상된다. 상기 연신가연단계에서 연신비 1.7~1.9로 연신되는 것이 가장 바람직할 것이다.In the stretching and twisting step, the composite yarn is stretched at a temperature of 150 to 180 DEG C while being stretched at a temperature of 150 to 180 DEG C. The composite yarn is preferably stretched at a stretching ratio of 1.5 to 2.0, and is stretched at a high temperature to improve crystallinity and physical properties. It is most preferable that the stretching is carried out at a draw ratio of 1.7 to 1.9 in the stretching and twisting step.
상기 복합사는 연신과 동시에 가연되는 것으로 가연은 꼬임수 500~2000 T/M으로 가연시키는 것이 바람직할 것이다.It is preferable that the composite yarn is twisted at the same time as the elongation, and the false twist is preferably twisted at a twist number of 500 to 2000 T / M.
상기 연신가연단계에서 온도가 150℃ 미만이면 가연이 적게 될 수 있으며, 180℃를 초과하면 미해연 및 모우강도 현상이 발생할 수 있다.If the temperature is lower than 150 ° C in the elongation and tearing step, the amount of tearing may be reduced. If the temperature is higher than 180 ° C, a non-tearing and a rolling strength phenomenon may occur.
상기 해연단계는 가연된 복합사를 해연하는 단계로 가연된 복합사를 100% 해연하여 권축성이 향상되고 면과 같은 터치감을 갖게된다. In the above-mentioned maraging step, the twisted composite yarn is twisted, and the twisted composite yarn is 100% twisted to improve the winding property and have a touch feeling like a face.
또한, 효과사는 부분연신사로 신도가 약 100~150%정도에서 연신가연단계와 해연단계를 지나면서 신도도 낮아진다. 상기 해연단계 후의 신도, 즉 잔류신도에 따라 신축성 및 면 질감이 차이가 발생된다. In addition, the degree of elongation is lowered as the elongation at the stretching step and the seaweed step at about 100 to 150% of elongation at the stretching yarn of the effect yarn. There is a difference in stretchability and surface texture depending on the elongation after the seam step, that is, the residual elongation.
본 발명에서는 면 질감을 높이기 위해 상기 해연단계 후의 효과사의 잔류신도는 20~50%인 것이 바람직하며, 공정성을 위해 상기 효과사의 잔류신도는 30~40%인 것이 가장 바람직할 것이다.In the present invention, it is preferable that the residual elongation of the effect yarn after the maraging step is 20 to 50% in order to improve the surface texture, and the residual elongation of the yarn is preferably 30 to 40% for the sake of fairness.
상기 해연단계 이후에 복합사를 권취하는 권취단계가 더 수행될 수 있을 것이다. 상기 권취단계는 일반적인 권취단계로 실시될 수 있을 것이다.A winding step of winding the composite yarn after the smoothing step may be further performed. The winding step may be performed in a general winding step.
