도 1은 본 발명이 적용되는 복합 가연공정의 개략도이다.1 is a schematic diagram of a composite combustion process to which the present invention is applied.

본 발명은 편평단면 폴리에스테르 복합 가연사 및 이의 제조방법에 관한 것이다. 보다 상세하게는, 본 발명은 광택 및 터치가 우수하고, 특히 이를 포함하는 직물의 염색 가공시, 흡한속건성을 가짐과 동시에 농색성(濃色性), 드레이프성(drape property), 반발 탄력성 및 소프트 터치를 동시에 발현하는 편평단면 폴리에스테르 복합 가연사 및 이의 제조방법에 관한 것이다.The present invention relates to a flat cross-section polyester composite twisted yarn and a method for producing the same. More specifically, the present invention is excellent in gloss and touch, in particular during dyeing processing of the fabric containing the same, having a quick-drying sweat absorption, dense color, drape property, resilience elasticity and soft The present invention relates to a flat cross-section polyester composite twisted yarn which simultaneously expresses a touch and a method of manufacturing the same.

종래의 심,초(core-sheath) 구조의 복합 가연사는 두 종류의 섬유의 신도 차이를 이용하여 동일한 가연영역에서 가연 정도의 차이를 유발하여 신도가 낮은 원사는 복합 가연사의 심사(core yarn)로 하고 신도가 높은 원사는 복합 가연사의 초사(sheath yarn)로 하여 초사가 심사를 감싸는 구조를 가지게 함으로써 제조가 가능하게 되었다.Conventional core-sheath composite twisted yarns use the difference in elongation of the two types of fibers to induce the difference in the degree of flammability in the same flammable area. The high-yield yarns were made of composite twisted yarn (sheath yarn) so that the yarn could have a structure surrounding the screening.

초사로서는 신도가 높은 세섬도 폴리에스테르 미연신사 또는 부분 배향사 등 이 사용되고, 심사로서는 폴리에스테르 태섬도 필라멘트사 또는 고수축성 원사를 사용하여, 가공사 표면의 촉감은 초사에 의한 소프트 터치가 발현되고, 태섬도의 코어사에 의해 드레이프성과 반발 탄력성이 발현된다. As the super yarn, high-fiber fine-stretch polyester non-drawn yarn or partially oriented yarn is used, and as the screening, polyester tasumido filament yarn or high shrinkable yarn is used. Drape and resilience are expressed by the core thread of fineness.

이와 같은 폴리에스테르 복합 가연사의 제조방법에 대해서는 일본 공개특허공보 제(평)7-126944호, 제(평)8-16292호 등에 개시된 바 있으나, 심사에 의한 소프트 터치나 벌키성 면에서는 어느 정도 만족할 만한 정도였지만, 자연스러운 광택과 흡한속건성 등의 기능성 및 염색성 측면에서는 만족스럽지 않다는 점이 현재의 실정이다.As for the manufacturing method of such a polyester composite twisted yarn, JP-A-7-126944 and JP-A-8-16292 Although disclosed, etc., it was somewhat satisfactory in terms of soft touch and bulkiness by screening, but is currently unsatisfactory in terms of functionality and dyeing properties such as natural gloss and sweat drying.

본 발명자들은 위에서 언급한 바와 같은 선행기술의 문제점을 해결하고자 예의 노력한 결과, 편평단면 폴리에스테르 POY를 초사로서 사용하고, 심사로서는 반고수축 폴리에스테르 SDY를 사용하여 편평단면 폴리에스테르 복합 가연사를 제조하는 경우, 염색성, 드레이프성 및 소프트 터치감이 우수할 뿐 아니라, 초사로서 사용되는 편평단면 폴리에스테르 POY의 이형단면에 의한 소광효과 및 부드러운 광택, 기능성이 발현된다는 사실을 확인하여 본 발명을 완성하기에 이르게 되었다.The present inventors have made diligent efforts to solve the problems of the prior art as mentioned above, and use a flat cross-section polyester POY as a superfiber, and use a semi-high shrink polyester SDY as a screening to prepare a flat cross-section polyester composite twisted yarn In this case, not only the dyeing, the drape and the soft touch feeling are excellent, but also the matting effect and the soft gloss and the functional properties of the flat cross-section polyester POY, which is used as the superfiber, are expressed. It came.

결국, 본 발명은 자연스러운 광택, 흡한속건성, 우수한 염색성, 발색성, 드레이프성, 소프트 터치, 벌키성이 뛰어난 편평단면 폴리에스테르 복합 가연사를 제공하기 위한 것이다.After all, the present invention is to provide a flat cross-section polyester composite twisted yarn having excellent natural gloss, sweat-absorbent quick-drying, excellent dyeing, color development, drape, soft touch, bulkiness.

본 발명은 편평단면 폴리에스테르 복합 가연사 및 이의 제조방법에 관한 것 으로, 보다 상세하게는 모노데니어가 1.5 내지 7데니어, 총 섬도가 30 내지 120데니어인 반고수축 폴리에스테르 SDY를 심사(B)로서 사용하고, 모노데니어가 0.5 내지 2데니어, 총 섬도가 50 내지 120데니어의 부분 배향된 편평단면 폴리에스테르 POY를 초사(A)로서 사용하여, 150 내지 210℃의 가연온도에서 1.0 내지 1.3의 연신비(D/R)로 연신하는 동시에 가연(false-twist)하고, 2차 세팅하는 것을 특징으로 하는 편평단면 폴리에스테르 복합 가연사의 제조방법 및 이러한 방법으로 제조한 폴리에스테르 복합가연사에 관한 것으로 편평단면 폴리에스테르 POY인 초사와 반고수축 폴리에스테르 SDY인 심사와의 비는 40 내지 60%: 60 내지 40%가 되도록 한다.The present invention relates to a flat cross-section polyester composite twisted yarn and a method for manufacturing the same, and more particularly, semi-shrinkable polyester SDY having 1.5 to 7 denier and total fineness of 30 to 120 denier as the screening (B). And a draw ratio of 1.0 to 1.3 at a combustion temperature of 150 to 210 DEG C, using a partially cross-sectional flattened polyester POY having a monodenier of 0.5 to 2 deniers and a total fineness of 50 to 120 deniers as the superfine yarn (A). D / R), the method of manufacturing a flat cross-section polyester composite twisted yarn characterized in that the false-twist and secondary setting at the same time, and the polyester composite twisted yarn prepared by the method, the flat cross-section polyester The ratio between the superfine yarn of POY and the screening of semi-high shrink polyester SDY is 40 to 60%: 60 to 40%.

이 경우 초사의 총 섬도가 40% 미만이면 직물을 제조 할 경우 원단의 터치가 저하되고 60%를 초과하는 경우 후가공 공정이 저하되는 문제점이 발생한다. 또한, 심사의 모노 데니어가 7데니어를 초과하는 경우, 교락 불량으로 염반이 발생하고 1.5데니어 미만이면 원단의 반발감이 불량해진다. 가연 온도 및 연신비는 사용 원사의 섬도, 모노 데니어 등을 고려해서 적정 조건을 설정함이 중요하다.In this case, if the total fineness of the weaving yarn is less than 40%, the touch of the fabric is lowered when the fabric is manufactured, and if it exceeds 60%, the post-processing process is deteriorated. In addition, when the mono-denier of the screening exceeds 7 deniers, the entanglement occurs due to poor entanglement, and when the mono-denier of the screening is less than 1.5 deniers, the repulsive feeling of the fabric becomes poor. It is important to set appropriate conditions in consideration of the fineness of a yarn used, a mono denier, etc. as a flammable temperature and draw ratio.

이하에서 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.

도 1은 본 발명이 적용되는 복합 가연공정의 개략도로서, 편평단면 폴리에스테르 복합 POY(A)와 반고수축 폴리에스테르 SDY(B)는 각각 분리된 상태에서 튜브 가이드를 통해 공급 로울러로 공급된다. 1 is a schematic diagram of a composite combustion process to which the present invention is applied, wherein a flat cross-section polyester composite POY (A) and a semi-high shrink polyester SDY (B) are respectively supplied to a feed roller through a tube guide in a separated state.

공급 로울러를 통과한 사조(絲條)는 공기 교락장치에서 공기 혼섬되어 공급 로울러를 통해서 제 1히터(2)를 통과하고, 가연부(3)을 거쳐서 공급 로울러 사이에서 동일한 연신비로 연신되는 동시에 가연된다. 이때, 가연부(3)는 트위스트 벨트 이외에 스핀들식 또는 마찰식 등 임의의 가연장치를 사용할 수 있다. The thread thread passing through the supply roller is mixed with air in the air entanglement device, passes through the first heater 2 through the supply roller, and is drawn at the same draw ratio between the supply rollers via the combustor 3 and at the same time do. At this time, the combustor 3 may use any combustor such as spindle type or friction type in addition to the twist belt.

연신, 가연된 사조는 제 2히터(4)에서 열고정되고, 오일링 로울러에 의해 급유처리된 다음, 와인더(5)에 권취된다.The stretched and twisted thread is heat-set in the second heater 4, lubricated by an oil ring roller, and then wound on the winder 5.

이와 같이 반고수축 폴리에스테르 SDY인 심사와 부분 배향된 편평단면 폴리에스테르 POY인 초사를 연신과 동시에 가연함으로써, 신도가 높은 초사가 복합 가연사의 표면 효과사로서 작용하고 반고수축 폴리에스테르 SDY는 심사로서 구성되어 신축성을 발현하게 된다. 특히, 직물 또는 편물의 염색가공 공정에서 심사로서 사용된 반고수축 폴리에스테르 SDY는 일반 잠재권축성 섬유에 비해 높은 수축률을 가지므로 균염성 및 농색성이 향상된다.Thus, by stretching and burning the screening of semi-high shrink polyester SDY and the super-fiber of partially oriented flat cross-section polyester POY, the high-strength superfiber acts as the surface effect yarn of the composite twisted yarn, and the semi-high shrink polyester SDY is configured as the screening. It expresses elasticity. In particular, semi-high shrink polyester SDY used as a screening in the dyeing process of fabrics or knitted fabrics has a higher shrinkage rate compared to general latent crimped fibers, thus improving the leveling and thickening properties.

본 발명의 반고수축 폴리에스테르 SDY의 비수 수축률은 8 내지 12%인 것이 본 발명의 목적을 달성하기 위해 적합하다.It is suitable that the specific shrinkage of the semi-high shrinkage polyester SDY of the present invention is 8 to 12% to achieve the object of the present invention.

또한, 심사로 사용되는 반고수축 폴리에스테르 SDY는 일반 연신사 대비 농색 발현이 가능하고, 일반 폴리에스테르 복합가연사에 비하여 염색성 및 소프트성이 더욱 우수하다. 따라서, 본 발명의 편평단면 폴리에스테르 복합가연사는 통상적인 폴리에스테르 복합가연사에 비하여 소프트 터치, 염색성 및 드레이프성이 더욱 우수하게 된다.In addition, the semi-high shrink polyester SDY used as the screening can express deep color compared to general stretched yarn, and has better dyeing and softness than general polyester composite twisted yarn. Therefore, the flat cross-section polyester composite twisted yarn of the present invention is more excellent in soft touch, dyeing and drape than conventional polyester composite twisted yarn.

이하에서 구체적인 실시 예 및 비교 예를 가지고 본 발명의 기술적 구성과 작용효과를 보다 상세히 설명하지만, 이들 실시 예는 단지 본 발명을 보다 명확하게 이해시키기 위한 것일 뿐, 본 발명의 범위를 한정하거나 제한하고자 하는 것은 아니다.Hereinafter, the technical configuration and effect of the present invention will be described in more detail with specific examples and comparative examples, but these examples are only intended to more clearly understand the present invention, and are intended to limit or limit the scope of the present invention. It is not.
