본 발명은 저수축성 폴리에스터사와 고수축성 폴리에스터사를 사용하는 폴리에스터 복합교락사의 제조방법에 관한 것으로서, 더욱 구체적으로는 상기 2종의 사에 열처리를 달리하고 공급율을 달리함과 동시에 공기교락처리함으로서 3차원의 교락구조와 이색조(two-tone)의 염색효과를 주는 폴리에스터 복합교락사의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester composite entangled yarn using a low shrinkage polyester yarn and a high shrinkage polyester yarn, and more specifically, to the two yarns by varying the heat treatment and supply rate, and at the same time, air handling treatment. The present invention relates to a method for producing a polyester composite entangled yarn which gives a three-dimensional entanglement structure and a two-tone dyeing effect.

일본특허공고 소 61-629는 필라멘트사를 단순하게 합사하면서 공기교락시키는 교락사의 제조방법인 바, 이 방법은 수축율차가 거의 없는 2본의 사를 연신가연기에 공기분사노즐만 설치한 장치로 교락사를 제조하는 것이므로 오버피드율의 조절이 불가능하고 분사공기에 의한 교락도와 교락수의 제어가 어려웠다.Japanese Patent Publication No. 61-629 is a manufacturing method of kinlock yarns which simply entangle filament yarns and entangle air.This method is a device in which two yarns with almost no difference in shrinkage rate are installed with an air spray nozzle only in a drawing combustor. It is impossible to control the overfeed rate and to control the degree of entanglement and the number of entanglements by injection air.

또 상기 방법은 권취방법이 링트래버스(Ringtraverse) 형식이므로 드레이프성과 촉감이 우수한 고품위의 호부용 직물의 경사를 제조하기에는 부적합하였다. 또 2종의 폴리에스터사를 사용하는 종래의 방법은 차등열처리, 오버피드율의 조정이 어려웠기 때문에 이 수축율의 극대화와 이색조의 충분한 발현이 매우 곤란하였다.In addition, since the winding method is a ring traverse type, the method is unsuitable for producing a warp fabric of a high quality calligraphy fabric having excellent drape and touch. In addition, in the conventional method using two kinds of polyester yarns, it is difficult to maximize the shrinkage rate and sufficiently express the dichroic color because the differential heat treatment and the adjustment of the overfeed rate are difficult.

본 발명은 이와 같은 종래의 문제점을 해결한 것으로서, 이하 상세히 설명하면 다음과 같다.The present invention solves such a conventional problem, described in detail below.

본 발명은 방사속도 5,000m/분 이상으로 제조한 결정화도 40% 이상 비정배향도 0.35이하, △n 140이하, 비수수축율 5% 이하인 폴리에스터사(이하 저수축사라 한다)와 비수수축율이 30~40%인 고수축 폴리에스터사(이하 고수축사라 한다)를 사용한다.The present invention is a polyester yarn (hereinafter referred to as a low shrinkage yarn) and a non-shrinkage ratio of 30% to 40% or more crystallinity degree 0.35 or less, Δn 140 or less, non-shrinkage rate 5% or less and the non-shrinkage is 30-40% Phosphorous high shrink polyester yarn (hereinafter referred to as high shrink yarn) is used.

고수축 폴리에스터사는 공중합성분으로 네오펜틸글리콜, 1, 4-부탄디올, 이소프탈릭애시드를 첨가하여 공중합하고 2,000~3,000m/분으로 방사한 것이다.High shrink polyester yarn is copolymerized by adding neopentyl glycol, 1, 4-butanediol, and isophthalic acid as a copolymerization component and spun at 2,000 to 3,000 m / min.

저수축사(A)는 공급롤러(2), 열판(H), 공급롤러(3)과 (4)를 거치도록 하며, 고수축사(B)는 공급롤러(1)과 공급롤러(4)를 거치도록 한다.The low shrinkage yarn (A) passes through the feed roller (2), the hot plate (H), the feed rollers (3) and (4), and the high shrinkage yarn (B) passes through the feed roller (1) and the feed roller (4). To do that.

이때 오버피드율은 공급롤러(1)에서는 0.5~2%, 공급롤러(2)에서는 2~4%, 공급롤러(3)에서는 1.0~3%, 그리고 공급롤러(4)에서는 0.5~1.0가 되게 한다.At this time, the overfeed rate is 0.5 to 2% in the feed roller 1, 2 to 4% in the feed roller 2, 1.0 to 3% in the feed roller 3, and 0.5 to 1.0 in the feed roller 4. do.

공급롤러(4)에서, 고, 저수축사는 합사되고 이어서 공기교락처리된 다음 권취된다.In the feed roller 4, the high and low shrinkage yarns are spun and then air entangled and then wound up.

공급롤러(1)의 오버피드율이 0.5% 미만이면 사절로 작업이 불가능하고, 2%를 초과하면 교락이 불균일해서 후공정에서 열수축이 교락이 풀리게 될 우려가 있다.If the feed roller 1 has an overfeed rate of less than 0.5%, it is impossible to trim the work. If the feed roller 1 exceeds 2%, the entanglement becomes uneven, and there is a concern that the heat shrinkage is released in the post process.

본 발명에서 공급롤러(1)의 오버피드율을 공급롤러(4)의 것보다 크게 한 이유는 공급롤러(4)에서의 사절을 방지하기 위함이다.The reason for making the overfeed rate of the feed roller 1 larger than that of the feed roller 4 in the present invention is to prevent trimming in the feed roller 4.

또 본 발명에서 공급롤러(2)의 오버피드율을 2.0~4.0%로 하여야 저수축사(A)가 열판(H)을 통과할때 발생하는 수축율만큼을 보상할 수 있고, 4%를 초과하면 열판(H)통과시 융착이 발생할 우려가 있다.In addition, in the present invention, the overfeed rate of the supply roller 2 should be 2.0 to 4.0% to compensate for the shrinkage rate generated when the low shrinkage yarn A passes through the hot plate H, and if it exceeds 4%, the hot plate (H) Fusion may occur during passing.

또 본 발명에서 공급롤러(3)의 오버피드율을 1.0~3.0%로 한 이유는 열판(H) 통과시에 발생되는 저수축사(A)의 수축율을 감안함과 동시에 공급롤러(4)에서의 사절을 방지하기 위함이고, 3%를 초과하면 롤러에 감길 우려가 있다. 본 발명에서는 공급롤러(2)의 오버피드율을 공급롤러(3)의 것과 같거나 크게하는데, 이는 공급롤러(2)의 오버피드율이 공급롤러(3)의 것보다 작으면 열판(H) 통과시 수축이 억제되어 저수축화가 진행되지 않으므로 가공지상에서의 크램프발현효과가 충분하지 않게 되기 때문이다.In the present invention, the overfeed rate of the feed roller 3 is set to 1.0 to 3.0% in consideration of the shrinkage rate of the low shrinkage yarn A generated when the hot plate H passes. In order to prevent thread trimming, if it exceeds 3%, the roller may be wound. In the present invention, the overfeed rate of the feed roller 2 is equal to or larger than that of the feed roller 3, which means that if the overfeed rate of the feed roller 2 is smaller than that of the feed roller 3, the hot plate H This is because the shrinkage is suppressed during the passage, so that the shrinkage does not proceed, and thus the effect of cramp expression on the processed paper is not sufficient.

또 본 발명에서는 공급롤러(3)의 오버피드율을 공급롤러(4)의 것보다 크게 하여서 저수축사(A)와 고수축사(B)의 주위를 피복하고 있는 형태의 코어-이펙트효과가 발현되도록 하였다.In the present invention, the overfeed rate of the feed roller 3 is made larger than that of the feed roller 4 so that the core-effect effect of the form covering the low shrinkage yarns A and the high shrinkage yarn B is expressed. It was.

공급롤러(4)의 오버피드율은 0.5~1.0%가 적합한데, 0.5% 미만이면 교락도가 떨어지고, 1.0%를 초과하면 불균일한 교락이 발생하기 때문이다.The feed rate of the feed roller 4 is suitably 0.5 to 1.0%, because if less than 0.5%, the degree of entanglement decreases, and if it exceeds 1.0%, uneven entanglement occurs.

또 본 발명에서는 저수축사(A)를 열판(H)에 통과시킨 다음 고수축사(B)와 합사시킴으로서 고, 저수축사간의 수축율차를 더욱 극대화시켰으며, 이때 열판(H)의 온도와 저수축사(A)의 통과시간을 변경시키면 저수축사(A)의 불균일한 수축성으로 말미암아 고수축사(B)와 합사, 공기교락시킨 후에 더욱 3차원의 교락구조와 이색효과를 발현시킬 수 있게 된다.In the present invention, the low shrinkage yarn (A) is passed through the hot plate (H) and then combined with the high shrinkage yarn (B) to maximize the difference in shrinkage between the high and low shrink yarns, wherein the temperature of the hot plate (H) and the low shrinkage yarn If the transit time of (A) is changed, the non-uniform shrinkage of the low shrinkage yarn (A) causes the three-dimensional entanglement structure and the dichroic effect to be expressed even after the high shrink yarn (B) is entangled and entangled with air.

본 발명에서 열판(H)의 온도는 150℃~190℃가 적합하며 접촉속도는 5~10m/초로 하였다.In the present invention, the temperature of the hot plate (H) is suitable 150 ℃ ~ 190 ℃ and the contact speed was 5 ~ 10m / sec.

종래에는 접촉속도를 합사하는 공급롤러(4)에 의해서만 조절하였으나, 본 발명에서는 공급롤러(3)를 두어 열처리시의 오버피드율과 접촉속도를 정확히 조절하도록 하였다.Conventionally, the contact speed is adjusted only by the feed roller 4, but in the present invention, the feed roller 3 is placed so as to accurately control the overfeed rate and the contact speed during heat treatment.

만약 190℃보다 높거나 접촉속도가 5m/초미만이면 저수축사가 융착되거나 비결정영역이 줄어들어서 최종사가 딱딱해진다.If it is higher than 190 ° C or the contact speed is less than 5m / second, the low shrinkage yarn is fused or the amorphous area is reduced and the final yarn becomes hard.

또 150℃보다 낮거나 접촉속도가 10m/초를 초과하면 코어-이펙트효과의 발현이 충분하지 못하다.If the temperature is lower than 150 ° C. or the contact speed exceeds 10 m / sec, the expression of the core-effect effect is insufficient.

본 발명에서 적당한 공기압력은 2.5~3.0kg/cm2이다.Suitable air pressure in the present invention is 2.5 ~ 3.0kg / cm 2 .

상술한 바와 같이 제조된 폴리에스터 복합교락사는 교락도와 교락수가 우수하고, 특히 열수축특성이 우수하여서 3차원구조의 크림프가 발현되었으며 최종직물상에서 미세한 파형(wave)효과를 나타내었다.The polyester composite entangled yarn prepared as described above was excellent in entanglement and entanglement, in particular, excellent in heat shrinkage characteristics, so that the crimp of three-dimensional structure was expressed and showed a fine wave effect on the final fabric.

아울러 염색후에 우수한 이색효과를 발현시켰다.In addition, after the dyeing, excellent dichroic effect was expressed.
