Description

토오크 없는 고벌키성 폴리에스테르 가연사의 제조방법 {Preparation of high-bulky torqueless draw textured polyester yarn}Manufacturing method of torque-free high-strength polyester twisted yarn {Preparation of high-bulky torqueless draw textured polyester yarn}

본 발명은 폴리에스테르 가연사의 제조방법에 관한 것으로서, 보다 구체적으로는 가연사 내부에 잔류토오크가 전혀 없는 고벌키성 가연사를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing polyester twisted yarn, and more particularly, to a method for manufacturing a high bulky twisted yarn having no residual torque inside the twisted yarn.

기존의 가연사 제조공정에서는 미연신 폴리에스테르 필라멘트의 가연사시에 디스크형, 핀형, 벨트형등의 기구를 사용하여 합사시키나 이들 공정에 의하면 두 필라멘트군이 s연인 경우에 합사후에는 z연이되어 합사후에도 가연사내에 토오크가 존재하게 되며 이로 인해 연신도를 높일경우에는 신축성이 저하되며, pet의 경우에는 신축성을 향상시키기 위해 특히 축소공정을 필요로 하여 공정이 번거롭고 비용 및 시간이 많이 드는 단점이 있었다.In the existing twisted yarn manufacturing process, the twisted yarns of the unstretched polyester filament are spliced by using a disk, pin, belt, etc., but according to these processes, when the two filament groups are s filament, they are z filamented after fusing. Torque is present in the twisted yarn afterwards, and thus, when the elongation is increased, the elasticity is decreased. In the case of pet, the process is cumbersome and costly and time-consuming because it requires a reduction process to improve the elasticity. .

따라서 본 발명은 상기한 바와 같은 선행기술의 제반 문제점을 해소할 수 있는 크림프 견뢰도가 높은 고벌키성 가연사를 제공하는 것을 기술적 과제로 한다.Therefore, the present invention is to provide a high bulky flammable yarn with high crimp fastness that can solve all the problems of the prior art as described above.

상기한 과제를 해결하기 위하여 본 발명자는 서로 반대의 가연방향을 가진 사끼리 합사하면 무연현상이 생기는 것에 착안하여 기존의 가연사공정에서의 합사에 잔재하는 토크를 제거하기 위하여 s-z동시가연용원반을 이용하여 s연을 가진 필라멘트와 z연을 가진 필라멘트를 제조하고 합사시켜 토크가 상쇄되도록 함과 동시에 복합사를 구성하는 미연신 폴리에스테르 필라멘트를 상기 가연공정전의 연신공정중에 기존의 열처리 온도보다 높은 온도로 열처리를 하고, 상기의 가연공정에서 기존의 가연계수보다 30%높은 가연계수로 가연을 함으로써 전체적으로 크림프 견뢰도가 향상되고 벌키성이 높은 폴리에스테르 가연사를 저비용의 간결한 공정으로 제조할수 있는 본 발명을 완성하게 된 것이다.In order to solve the above problems, the present inventors pay attention to the fact that lead-free phenomena occur when weaving yarns having opposite flammable directions to each other to remove the torque remaining in the coarse yarn in the conventional twisting yarn process. Manufacture filaments with s edges and filaments with z edges so that torque is canceled and at the same time the unstretched polyester filaments constituting the composite yarn are higher than the existing heat treatment temperature during the stretching process before the twisting process. In the present invention, the present invention can produce polyester twisted yarn with low cost and simple process by improving crimp fastness and high bulkiness by performing heat treatment with the above-mentioned. It is completed.

본 발명에 의하면 두군의 필라멘트를 200∼230℃로 열처리를 하고 연신을 한 후, 디스크형의 s-z동시가연용원반을 이용하여 s형 가연을 가진 필라멘트와 z형 가연을 가진 필라멘트를 제공하는 공정에 있어서 이 두군의 필라멘트군에 기존의 가연계수보다 20∼40%(바람직하게는 30%)의 가연(false twist)을 더 가하고 해연할 때 각 필라멘트군에 미세한 루프를 형성시켜 가연사를 제조하는 것을 특징으로 하는 토오크 없는 고벌키성 폴리에스테르 가연사의 제조방법이 제공된다.According to the present invention, after heat-treating and stretching two groups of filaments at 200 to 230 ° C., a process of providing filaments with s type combustibles and filaments with z type combustibles using a disk type sz simultaneous combustible disc. In this case, a false twist of 20-40% (preferably 30%) is added to these two groups of filaments, and a fine loop is formed in each group of filaments when decomposing them to produce false twisted yarn. There is provided a method for producing a torque-free high bulky polyester false twist yarn.

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

본 발명에서 출발물질로 사용되는 폴리에스테르 필라멘트군은 미연신 폴리에틸렌테레프탈레이트(PET) 필라멘트 또는 미연신 폴리트리메틸렌 테레프탈레이트(PTT) 필라멘트가 사용될 수 있다. 상기 미연신 폴리에스테르 필라멘트군을 s-z동시가연원반에 의한 가연공정을 하기전에 히터에 의해 통상의 열처리온도인 180 ∼210℃의 온도보다 10% 더 높은 200 ∼ 230℃(바람직하게는 210℃가 적당하다.)에서 열처리한다. 200℃미만의 온도에서는 우수한 크림프 견뢰성을 확보할 수 없으며 230℃를 초과하는 온도에서는 생산되는 추간의 염색편차가 크게 나타난다.The polyester filament group used as a starting material in the present invention may be an unstretched polyethylene terephthalate (PET) filament or an unstretched polytrimethylene terephthalate (PTT) filament. Before the unstretched polyester filament group is subjected to the sintering process using the sz simultaneous flammable disc, 200 to 230 ° C (preferably 210 ° C) is 10% higher than the normal heat treatment temperature of 180 to 210 ° C by a heater. Heat treatment). At temperatures below 200 ° C, excellent crimp fastness cannot be ensured, and at temperatures exceeding 230 ° C, the dyeing deviations of the intervertebral bodies produced are large.

상기의 열처리된 각각의 필라멘트군을 s-z동시가연원반을 이용하여 가연을 가하게 되는데 s-z동시가연원반의 벨트의 회전속도를 높임으로써 양 필라멘트군에 기존의 가연각인 42°보다 20∼40%(바람직하게는 30%) 높은 50.4∼58.8°의 가연각으로 가연하고, 해연할 때 각 필라멘트군에 미세한 루프를 형성시킨다. s-z동시가연원반에서는 원반의 양면에 각각 1개의 벨트가 접하도록 부설되어 있는데 이 두 개의 벨트사이로 각 필라멘트가 공급되면서 벨트와 원반의 마찰에 의해 한쪽은 s형 가연을 가진 필라멘트군이, 한쪽은 z형 가연을 가진 필라멘트군이 제조되며, 양 필라멘트군은 가연기를 벗어나면서 가연이 풀리게(해연) 되면서 다시 꼬임이 없는 필라멘트 다발이 되는 것이다.Each heat-treated filament group is subjected to combustion using sz simultaneous combustion disc. By increasing the rotational speed of the belt of sz simultaneous combustion disc, both filament groups are 20-40% (preferably 42 °, which is the conventional combustion angle). (30%), and burns at a high twist angle of 50.4 ~ 58.8 °, and forms a fine loop in each filament group when defrosting. sz Simultaneous flammable discs are laid so that one belt is in contact with both sides of the disc, and each filament is supplied between the two belts, and one side of the filament group has s-type flammable by friction between the belt and the disc, and one side is z A group of filaments with type flammables are produced, and both filament groups are untwisted and filament bundles as the filaments are released (haze) out of the combustor.

해연이 된 필라멘트군은 외관상으로는 꼬임을 가지지 아니하나 필라멘트 내부에 꼬임과 반대방향의 토오크가 잔류하게 된다. 가연기를 통과한 필라멘트군은 열처리를 다시 하여 안정화시키고 교락공정에 의해 합사를 하고 권취가 될 수 있는데 본 발명에서는 상기의 합사에 의해 두 필라멘트군에 잔류하는 반대방향의 토오크가 서로 상쇄되어 결과적으로 가연사 내부에는 토오크를 가지지 않게 된다.The filament group which is decomposed does not have a twist in appearance, but the torque in the opposite direction to the twist remains in the filament. The filament group passed through the combustor can be stabilized by heat treatment again, and can be spliced together by the entanglement process and can be wound. In the present invention, the opposite torques remaining in the two filament groups are canceled by the spliced yarn and consequently combustible There is no torque inside the yarn.

이하 다음의 실시예에서는 두군의 폴리에스테르 필라멘트사를 열처리하고, s-z동시가연원반에 의해 서로 반대방향의 토오크를 가진 필라멘트군으로 폴리에스테르 복합 가연사를 제조하는 비한정적인 예시를 하고 있다.In the following examples, a non-limiting example of heat-treating two groups of polyester filament yarns and manufacturing a polyester composite twisted yarn with a filament group having torques in opposite directions by the s-z simultaneous combustion disc is performed.

Increase the false twist at the angle of 54 ° for both filament groups, and form a fine loop when decomposing them, then heat-treat them again and set them together. PET twisted yarn was prepared.

상기의 가연사의 특성으로 CC 값(value)과 CS 값(value)은 헤버레인법(herberlein)에 의해 측정한 권축도의 평가방법이며 CC 값(value)은 크림프 컴포즈(crimp compose)성을 나타내는 수치이며, CS 값(value)은 크림프 스트레치(crimp stretch) 성을 나타내는 수치인데 양 수치가 높을수록 크림프견뢰도가 우수한 가연사이다.The CC value and CS value are characteristics of the false twisted yarn, and the crimping degree is measured by the Heberlein method, and the CC value indicates crimp compose. It is a numerical value, and the CS value is a value indicating crimp stretch property. The higher the value, the more false twisted yarn is the crimp fastness.

상기한 바와 같이 본 발명에 의하면 가연사 내부에 토오크가 잔류하지 않으면서도 크림프 견뢰도가 우수한 고벌키성 폴리에스테르 가연사를 제조하는 것이 가능하게 되며, 제사공정후의 연사, 연지 또는 사이징 등의 열처리 공정들에서도 크림프 견뢰도를 높이고 신축성을 향상시킬 수 있는 동시에 축소공정의 생략으로 인한 공정단축 및 비용절감의 효과를 얻을 수 있다.As described above, according to the present invention, it is possible to manufacture a high bulky polyester twisted yarn having excellent crimp fastness without remaining torque in the twisted yarn, and also in heat treatment processes such as twisting, rolling or sizing after the weaving process. It can improve the crimp fastness and improve the elasticity and at the same time, it can reduce the process and cost by omission of the reduction process.
