종래의 멜란지(Melange) 효과를 가지는 직편물은 패턴 및 종류도 다양하여 직편물상에서 멜란지 효과를 부여하는 기술은 다양하게 적용될 수 있다. 예를 들면 염색성이 상이한 이종 소재 필라멘트(천연섬유를 포함하여)를 공기교락 장치에 의해 교락을 부여한다든지 또는 연사공정 등에서 합연을 하든지 또는 교편(배열직물) 등을 통해 직편물상에서 스트라이프를 부여하든지 하는 기술들은 공지의 기술로 알려져 있다.The conventional knitted fabric having a melange effect has a variety of patterns and types, and thus a technique of providing a melange effect on the knitted fabric may be variously applied.

There are a variety of products.

본 발명의 목적은 폴리에스테르 복합 가연사의 제조방법 및 폴리에스테르 복합 가연사에 있어서, 직편물상에서 고도의 부품성을 가지며 우수한 멜란지 효과를 발현할 수 있는 폴리에스테르 복합 가연사의 제조방법 및 폴리에스테르 복합 가연사를 제공하는데 있다.An object of the present invention is a method for producing polyester composite twisted yarn and polyester composite twisted yarn, a method for producing polyester composite twisted yarn and polyester composite twisted yarn which can express excellent melange effect with high component properties on knitted fabric. To provide four.

본 발명에 의하면 폴리에스테르 복합 가연사의 제조방법에 있어서, 폴리에스테르 염반사와 양이온 염료 가염성 폴리에스테르사를 공기교락장치를 사용하여 90%보다 높은 교락강도 및 교락수 60개/m 이상으로 교락한 후, 얻어진 교락사를 100℃<복합 가연온도<160℃ 범위 내의 복합 가연온도 및 1.05<복합 가연연신비<1.15 범위 내의 복합 가연연신비의 조건하에서 복합가연하는 것을 특징으로 하는 폴리에스테르 복합 가연사의 제조방법이 제공된다.According to the present invention, in the method for producing a polyester composite twisted yarn, the polyester salt reflector and the cationic dye salt soluble polyester yarn are entangled with an entanglement strength higher than 90% and the number of entanglements more than 90% / m using an air entanglement device. Thereafter, the obtained twisted yarn is subjected to composite combustion under the conditions of the composite combustion temperature within the range of 100 ° C. <composite combustion temperature <160 ° C. and the composite combustion draw ratio within the range of 1.05 <composite combustion ratio <1.15. This is provided.

또한 본 발명에 의하면 폴리에스테르 복합 가연사에 있어서, 상기 기재의 제조방법으로 제조된 폴리에스테르 복합 가연사가 제공된다.Moreover, according to this invention, in polyester composite twisted yarn, the polyester composite twisted yarn manufactured by the manufacturing method of the said base material is provided.

이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명은 폴리에스테르 염반사와 양이온(Cation) 염료 가염성 폴리에스테르사를 사용하여 가연기상에서 복합가연 가공을 행할 때 특별한 가연 가공조건을 통하여 사에 크림프 특성 및 심초사 구조를 부여하여 직편물상에서 고도의 부품성을 가지면서 특이한 멜란지 효과를 갖도록 하는 신규한 폴리에스테르 복합가연사의 제조방법 및 폴리에스테르 복합 가연사에 관한 것이다.The present invention is to give the crimp characteristics and deep weed yarn structure to the yarn through the special twist processing conditions when performing the composite twist processing on the combustor using polyester salt reflecting and cationic dye salt-resistant polyester yarn The present invention relates to a novel polyester composite twisted yarn production method and polyester composite twisted yarn having a high component properties and a unique melange effect.

좀 더 구체적으로 설명하면 상기 폴리에스테르 염반사와 양이온 염료 가염성 폴리에스테르사를 크릴부에서 합사하고 가연부 이전에서 공기 교락장치에 의해 교락을 부여한 다음 가연부에서 저온 열처리함을 특징으로 하는 복합가연 방법이다.In more detail, the composite flame retardant, characterized in that the polyester salt reflection and the cationic dye salt soluble polyester yarns are spliced in the krill portion, impregnated by an air interlocking device before the combustible portion, and then subjected to low temperature heat treatment at the combustible portion. Way.

일반적으로 신도 차이가 있는 이종 소재, 예를 들면 폴리에스테르 필라멘트 및 폴리에스텔 부분배향사를 공기교락 장치에 의해 교락을 부여한 복합사를 직편물로 제조하게되면 후공정에서 축소공정등의 열처리를 거치게 되면서 이러한 복합사는 심초형 구조를 발현하게 되는데, 이는 고신도인 폴리에스테르 부분배향사가 열처리 공정등을 거치면서 더 이상 수축현상이 발현되지 않거나 심지어는 신장하는 거동을 보이는 반면에 폴리에스테르 필라멘트는 여전히 수축현상이 발현되어 두 소재간의 길이 변화를 수반하게 되고 공기 교락장치에 의해 부여된 교락점이 고정되어 있어 이 두소재의 길이변화를 잡고 있기 때문에 심초형 복합구조를 나타내게 되고 따라서 직편물 상에서 부품성이 우수한 특성을 발현하게 된다.In general, when heterogeneous materials having different elongation, such as polyester filament and polyester partial alignment yarn, are manufactured from a knitted fabric in which a composite yarn impregnated with an air entanglement device is subjected to heat treatment such as a reduction process in a post process. These composite yarns develop a deep eccentric structure, which is that the high-strength polyester partial alignment yarn no longer contracts or even elongates during the heat treatment process, while the polyester filament still shrinks. This results in the change of length between the two materials and the interlock point given by the air entanglement device to fix the length change of the two materials. Will be expressed.

즉, 본 발명은 특유한 가연조건을 통하여 직편물 상에서 심초형 복합구조를 발현시켜 고도의 부품성을 부여하고 각 사에 크림프 특성을 가미하여 부드러운 질감을 구현함과 동시에 연사등 후공정에서 공정 문제를 야기하지 않으면서 양이온 염료로 염색시 태세의 멜란지 효과를 가지는 복합가연사를 제조하는 것이다.In other words, the present invention expresses a deep sheath-type complex structure on the knitted fabric through the unique flammable conditions to impart a high degree of part properties, and adds a crimp characteristic to each yarn to realize a smooth texture and at the same time to process problems in post-processing such as twisting It is to produce a composite twisted yarn having a melange effect of poised when dyed with a cationic dye without causing.

본 발명의 폴리에스테르 복합 가연사의 제조방법은 폴리에스테르 염반사와 양이온 염료 가염성 폴리에스테르사를 공기교락장치를 사용하여 90%보다 높은 교락강도 및 교락수 60개/m 이상으로 교락한 후, 얻어진 교락사를 100℃<복합 가연온도<160℃ 범위 내의 복합 가연온도 및 1.05<복합 가연연신비<1.15 범위 내의 복합 가연연신비의 조건하에서 복합가연하는 것을 특징으로 한다.The method for producing polyester composite false twisted yarn of the present invention is obtained by entangled polyester salt reflector and cationic dye salted polyester yarn with an entanglement strength of more than 90% and the number of entanglements of 60 or more using an air entanglement device. The twisted yarn is characterized in that the composite twist is carried out under the conditions of the complex flammability ratio within the range of 100 ° C. <complex combustion temperature <160 ° C. and the complex flammability ratio within the range of 1.05 <compound flammability ratio <1.15.

본 발명의 폴리에스테르 염반사와 양이온 염료 가염성 폴리에스테르사는 공기교락장치를 사용하여 90%보다 높은 교락강도 및 교락수 60개/m 이상으로 교락하는 것이 바람직하다. 여기서 교락강도는 0.15g/d 하중부여시 잔류 교락수를 백분율(%)로 나타낸 것으로, 0.15g/d 하중부여시 잔류 교락수 %가 90% 보다 높아야 하고 교락수가 60개/m 이상이어야 후공정, 특히 연사공정중 펀와인딩(Pirn-winding) 공정에서의 해사속도 및 장력에 대응하여 공정 문제를 야기하지 않는다. 이러한 수준을 만족시키기 위해서는 가연부 이전에서 공기 교락장치에 의해 폴리에스테르 염반사와 양이온 염료 가염성 폴리에스테르사에 교락을 부여할 때에 공기압 1.5㎏/㎠ 이상, 교락부여 노즐의 직경이 1.4㎜ 이상, 공급(Feeding)부에서의 과공급율(Over Feed) 1∼3% 부여에 의하여 사장력을 5g 이하로 관리하여 달성할 수 있다.It is preferable to entangle the polyester salt reflector of the present invention and the cationic dye chlorinated polyester yarn to an entanglement strength of more than 90% and the number of entanglements of 60 or more using an air entanglement device. In this case, the entanglement strength is the percentage of residual entanglement when loading 0.15g / d as a percentage, and when the loading is 0.15g / d, the percentage of entanglement should be higher than 90% and the number of entanglements should be more than 60 / m. In particular, it does not cause process problems in response to the dissolution speed and tension in the punch-winding process. In order to satisfy such a level, when the entanglement is applied to the polyester salt reflection and the cationic dye chlorinated polyester yarn by an air entanglement device before the combustible portion, the air pressure is 1.5 kg / cm 2 or more, the diameter of the entanglement nozzle is 1.4 mm or more, It can be achieved by managing the dead force to 5g or less by giving 1 ~ 3% of over feed in the feeding part.

또한, 복합 가연온도가 100℃ 이하인 경우는 복합가연시 가연장력이 지나쳐 적정 사도를 형성하기 곤란하며 가연에 의한 크림프 특성이 저하되고 복합가연사 제조이후 후공정, 예를들면 연사-연지 공정등의 열처리 공정에서 수축성 차를 유발하게 되어 직물상에서 양변색차를 일으키는 등 품질특성을 저하시키게 된다. 또한 복합 가연온도가 160℃ 이상인 경우는 사용된 폴리에스테르 염반사의 태세(Thick & Thin) 효과를 반감시킬뿐 아니라 태(Thick)부위의 미해연 발생등으로 품질을 저하시키게 된다.In addition, when the composite combustion temperature is 100 ° C or less, it is difficult to form an appropriate slope due to excessive flammability at the time of composite combustion, deterioration of crimp characteristics due to combustion, and heat treatment of post-processing, for example, twist-delay process after the production of composite twisted yarn. The shrinkage difference is caused in the process, and thus the quality characteristics such as the color change difference are caused on the fabric. In addition, when the composite flammable temperature is higher than 160 ° C, not only the half-thickness and thinning effect of the polyester salt reflector used is deteriorated, but also the quality is deteriorated due to the non-flammable generation of the thick part.

또한, 복합 가연연신비가 1.05 이하인 경우는 적정한 가연장력을 유지하기 곤란하여 실걸이성 곤란등 작업 공정성이 불량하게 되고, 복합 가연연신비가 1.15이상일 경우는 사용된 폴리에스테르 염반사의 태세(Thick & Thin) 효과를 반감시킬뿐 아니라 직편물로 제조시에 후공정에서 축소공정등의 열처리를 거치게 되면서 심초형 구조발현 특성을 약화시키게 된다.In addition, when the composite flammability ratio is 1.05 or less, it is difficult to maintain an appropriate flammability, resulting in poor work fairness, such as difficulty in thread hooking, and when the composite flammability ratio is 1.15 or more, the state of used polyester salt reflector (Thick & Thin) In addition to halving the effect, the fabrication of the knitted fabric undergoes a heat treatment such as a post-shrinkage reduction process, thereby weakening the characteristics of the myocardial structure.

본 발명의 폴리에스테르 염반사는 자연 연신비(Necking Draw Ratio) 1.32∼2.25로 방사되어 배향도가 20×10-3∼60×10-3인 부분 배향사를 연신한 것이 바람직하다.It is preferable that the polyester salt reflecting yarn of the present invention is spun at a natural draw ratio of 1.32 to 2.25 to draw a partially oriented yarn having an orientation of 20 × 10 −3 to 60 × 10 −3 .

또한, 본 발명의 폴리에스테르 염반사는 부분 배향사를 연신할 때 0.85≤연신비/자연연신비≤1.05 범위 내의 연신비/자연연신비 및 유리전이온도(Tg)<연신기의 연신온도<Tg+80℃ 범위 내의 연신기의 연신온도의 조건하에서 수행되는 것이 바람직하다.In addition, the polyester salt reflecting yarn of the present invention, when stretching the partial orientation yarn, the draw ratio / natural draw ratio and the glass transition temperature (Tg) <draw temperature <Tg + 80 ℃ range within the range of 0.85≤ draw ratio / natural draw ratio ≤ 1.05 It is preferably carried out under the condition of the stretching temperature of the stretching machine in the chamber.

부분 배향사를 연신비/자연 연신비가 0.85 이하로 연신할 경우에는 연신된 폴리에스테르 염반사의 태(thick,太)부위의 길이가 세(thin,細)부위의 길이보다 길어져서 가연기에서 양이온 염료 가염성 폴리에스테르사와 복합가연공정시에 공정성이 불량하고 복합가연의 가공범위가 적으며, 이러한 복합 가연사를 사용하여 직편물을 제조하면 태(thick)부위가 강조되어 멜란지 효과가 나빠져 직편물의 품위를 떨어뜨린다.When the partial orientation yarn is drawn at a draw ratio / natural draw ratio of 0.85 or less, the length of the thick portion of the stretched polyester salt reflecting yarn is longer than that of the thin portion so that the cationic dye in the combustor Poor processability in the composite flame retardant polyester yarn and composite flame retardant process, and the processing range of the composite flame retardant is small. When fabrics are manufactured using such composite flame retardant yarns, thick parts are emphasized, and the melange effect is worsened. Degrades dignity.

또한, 부분 배향사를 연신비/자연 연신비가 1.05 이상으로 연신할 경우에는 연신된 폴리에스테르 염반사의 태(thick)부위의 길이가 세(thin)부위의 길이보다 지나치게 짧아져서 염반 효과가 불충분하여 최종 직편물상의 멜란지 효과를 반감시킨다.In addition, when the partial orientation yarn is drawn with a draw ratio / natural draw ratio of 1.05 or more, the length of the thick portion of the drawn polyester salted yarn becomes too short than the length of the thin portion, resulting in insufficient salt effect. Half the melange effect on the knit fabric.

본 발명의 폴리에스테르 염반사는 연신기를 사용하여 일반적인 방법으로 제조하는것도 가능하며, 스핀 드로우 방식으로 제조하는 것도 가능하다. 폴리에스테르 염반사를 연신기를 사용하여 일반적인 방법으로 제조하는 경우에는 상기와 같이 연신온도가 폴리에스테르의 유리전이온도(Tg)보다 높고 폴리에스테르의 유리전이온도(Tg) + 80℃보다 낮게하여 연신하는 것이 바람직하며, 스핀드로우 방식으로 제조하는 경우에는 연신온도가 폴리에스테르의 유리전이온도(Tg)보다 높고 폴리에스테르의 유리전이온도(Tg) + 25℃보다 낮게하여 연신하는 것이 바람직하다.Polyester salt reflection of the present invention can be produced by a general method using a stretching machine, it is also possible to produce a spin draw method. When polyester salt reflection is produced by a general method using a drawing machine, as described above, the drawing temperature is higher than the glass transition temperature (Tg) of the polyester and lower than the glass transition temperature (Tg) of the polyester + 80 ° C. In the case of the spin draw method, the stretching temperature is higher than the glass transition temperature (Tg) of the polyester and lower than the glass transition temperature (Tg) of the polyester + 25 ° C.

폴리에스테르 염반사를 연신기를 사용하여 일반적인 방법으로 제조하는 경우 연신온도를 폴리에스테르의 유리전이온도(Tg) 이하로 하는 경우에는 제조된 폴리에스테르 염반사의 비수수축율이 과다하게 커지게 되어 가연기 상에서 복합가연 가공시에 사에 과다 수축 현상이 발생하여 장력 조절이 용이하지 않아 가연 공정성을 저해하게 될뿐 아니라 짧은 태(thick)부위가 많이 발생하여 최종 직편물에서 멜란지 효과를 반감시킨다. 또한, 연신온도를 폴리에스테르의 유리전이온도(Tg) + 80℃ 이상으로 하는 경우에는 제조된 폴리에스텔 염반사의 태(thick)부위와 세(thin)부위의 구분이 불명확해져 최종 직편물상에서 멜란지 효과를 기대하기 어렵다.When polyester salt reflection is produced by a general method using a drawing machine, when the stretching temperature is less than or equal to the glass transition temperature (Tg) of the polyester, the non-shrinkage rate of the produced polyester salt reflection becomes excessively large, resulting in the combustor phase. In the composite twist processing, overshrinkage occurs in the yarn, which is not easy to control the tension, which impairs the flammability process, and also generates a lot of short thick parts to halve the melange effect in the final knitted fabric. In addition, when the stretching temperature is higher than the glass transition temperature (Tg) of the polyester + 80 ° C, the distinction between the thick and thin portions of the polyester dyed yarn produced is unclear and the melange on the final knitted fabric Hard to expect effects.

또한, 본 발명의 폴리에스테르 염반사는 부분 배향사를 연신할 때 0.85≤연신비/자연연신비≤1.05 범위 내의 연신비/자연연신비 및 유리전이온도(Tg)<스핀드로우 공정의 연신온도<Tg+25℃ 범위 내의 스핀드로우 공정의 연신온도의 조건하에서 수행되는 것이 바람직하다.In addition, the polyester salt reflecting yarn of the present invention draws a draw ratio / natural draw ratio and glass transition temperature (Tg) in the range of 0.85 ≦ stretch ratio / natural draw ratio ≦ 1.05 when stretching the partially oriented yarn <Tg + 25 ° C. It is preferably carried out under the conditions of the stretching temperature of the spin draw process in the range.

폴리에스테르 염반사를 스핀드로우 방식으로 제조하는 경우 연신온도를 폴리에스테르의 유리전이온도(Tg) 이하로 하는 경우 및 연신온도를 폴리에스테르의 유리전이온도(Tg) + 25℃ 이상으로 하는 경우는 연신기를 사용하여 일반적인 방법으로 제조하는 경우와 마찬가지 이유로 바람직하지 않다. 특히, 연신온도를 폴리에스테르의 유리전이온도(Tg) + 25℃ 이상으로 하는 경우는 스핀드로우 공정중 사떨림 현상이 발생하여 공정이 나빠진다.In the case of producing the polyester salt reflection by the spin draw method, the stretching temperature is lower than the glass transition temperature (Tg) of the polyester and the stretching temperature is higher than the glass transition temperature (Tg) of the polyester + 25 ℃ It is not preferable for the same reason as that produced by the general method using the group. In particular, when the stretching temperature is more than the glass transition temperature (Tg) of the polyester + 25 ° C., a blurring phenomenon occurs during the spin draw process, and the process worsens.
