Description

폴리에스테르 혼섬사의 제조방법Manufacturing method of polyester blended yarn

본 발명은 폴리에스테르 복합사의 제조방법에 관한 것으로서, 더욱 상세하게는 자연연신비가 서로 다른 2종의 원사를 공기교락 처리한 후 고온 연신하여 제직성과 후가공성이 양호하며, 직편성 후 열처리하였을 때 우수한 표면효과 및 벌키성을 나타내는 폴리에스테르 혼섬사의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester composite yarn, and more particularly, two kinds of yarns having different natural draw ratios are subjected to air entanglement, followed by high temperature drawing, so that weaving and post-processing properties are good, and excellent after heat treatment after knitting. The present invention relates to a method for producing a polyester blend fiber which exhibits surface effect and bulkiness.

종래 실의 길이 방향으로 미세구조를 부여하는 방법으로는 수축특성이 서로 상이한 2종의 원사를 유체교락장치를 통해 혼섬하는 방법이 보편화되어 있다( 일본 특허공고 81-27608호, 일본 공개특허 81-140114호).Conventionally, as a method of imparting a microstructure in the longitudinal direction of a yarn, a method of blending two kinds of yarns having different shrinkage characteristics through a fluid entanglement device is common (Japanese Patent Publication 81-27608, Japanese Patent Publication 81-27). 140114).

이러한 종래 기술로 제조된 이수축 혼섬사는 정련 축소 공정 후에는 저수축 성분이 원단상에 루프를 형성하여 상대적으로 무장력 열처리를 계속 받기 때문에 꾸준히 수축하여 최종 가공지 상에서의 미세구조 발현이 다소 미흡하며, 고수축 성분의 수축율 유지를 위해 비교적 고온 연신이 불가능하여 염색 불균일의 원인이 되어 왔다.The bishrink blended yarn prepared by the prior art shrinks steadily because the low shrinkage component forms a loop on the fabric and is subjected to relatively heat-free heat treatment after the refinement reduction process, and thus the microstructure on the final processed paper is somewhat insufficient. In order to maintain the shrinkage ratio of the high shrinkage component, it is impossible to draw at a relatively high temperature, causing dyeing unevenness.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로 연신전신장능력이 다른 두 사조를 개개의 신장능력에 따른 연신배율을 적용치 않고 신장능력이 많은 미연신사가 상대적으로 적은 연신비로 연신되도록 동시 연신배율을 부여함에 의해, 상기 사는 신장회복이 적어져서 사장차를 유발시키게 된다. 이는 사조간의 수축특성차가 아닌 40~80%의 신장회복 특성차에 의한 사장차로서, 본 발명의 목적은 제직성과 후가공성이 양호하며 직편성 후 열처리하였을 때 우수한 표면효과 및 벌키성을 나타내는 폴리에스테르 혼섬사를 제공하는 데에 있다.The present invention is to solve the problems of the prior art at the same time to draw two relatively different stretching capacity without stretching ratio according to the individual stretching capacity of the two yarns with the stretching ability to draw at a relatively small draw ratio By imparting, the yarn causes less kidney recovery, causing infertility. This is a dead-weight car by 40 ~ 80% elongation recovery property difference, not the shrinkage property difference between yarns. The object of the present invention is good weaving and post-processing, and polyester showing excellent surface effect and bulkiness when heat-treated after knitting. It is to provide the blended yarn.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 효과사와 심사를 교락처리한 후 연신하여 폴리에스테르 혼섬사를 제조함에 있어서, 효과사로서 자연연신비가 2.7~3.2배인 원사와 심사로서 자연연신비가 2.0~2.5배인 원사를 교락하되 두 원사의 자연연신비의 차를 0.5~1.2로 하여 이완상태에서 공기 교락처리한 다음, 제1연신 로울러의 온도를 유리전이온도보다 30~60℃ 높은 온도로 하고, 열처리판 온도를 100~230℃로 해서 동시 연신하는 것을 특징으로 한다.In the present invention, in the production of polyester blended yarn by drawing after entangled the effect yarn and the screening, the yarn is a natural draw ratio of 2.7-3.2 times as an effect yarn and a yarn having a natural draw ratio of 2.0-2.5 times as a screening yarn, but the two yarns After the air draw treatment in the relaxed state with the difference in the natural draw ratio of 0.5 to 1.2, the temperature of the first draw roller is 30 to 60 ℃ higher than the glass transition temperature, and the heat treatment plate temperature is 100 to 230 ℃ It is characterized by stretching.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

자연연신비가 1.2를 초과하는 원사들을 사용하는 경우에는 신장 탄성차가 커서 원사상태에서 이미 루프를 형성하여 제직통과성이 불량하므로 바람직하지 못하다.In the case of using yarns having a natural draw ratio of more than 1.2, it is not preferable because the stretch elasticity difference is large and weaving already forms a loop in the yarn state, so that the weaving permeability is poor.

또한, 자연연신비차가 0.5미만일 때는 사조간 신장특성이 비슷하여 본 발명의 효과를 기대할 수 없다.In addition, when the natural draw ratio is less than 0.5, the inter-extension stretch characteristics are similar, and the effect of the present invention cannot be expected.

유체노즐 중의 공기압은 1.0~3.0kg/㎤이 적당하며, 이 때 공기압이 3.0kg/㎤를 초과하면 염색시 교락점이 나타나게 된다.The air pressure in the fluid nozzle is suitably 1.0 to 3.0 kg / cm 3, and when the air pressure exceeds 3.0 kg / cm 3, an entanglement point appears during dyeing.

공기교락처리 후의 연신배율은 가장 낮은 자연연신비 원사의 자연연신비 부근의 연신배율로 하는 것이 바람직하다.It is preferable that the draw ratio after the air entanglement treatment be the draw ratio near the natural draw ratio of the lowest natural draw ratio yarn.

또한, 이 때의 연신은 유리전이온도보다 30~60℃ 높은 비교적 고온에서 실시하여야 자연연신배율 부근의 저배율 연신에 따른 연신 불균일을 억제할 수 있다. 즉, 불균일 연신부의 상대적 비결정부를 고온 연신으로 결정화와 배향을 증가시켜 불균일 연신 현상을 감소시킬 수 있다.In addition, the stretching at this time should be carried out at a relatively high temperature 30 ~ 60 ℃ higher than the glass transition temperature to suppress the stretching unevenness due to the low magnification stretching near the natural stretching magnification. That is, the non-uniform stretching of the non-uniformly stretched portion may be increased by high temperature stretching to increase crystallization and orientation, thereby reducing non-uniform stretching.

그리고 열판의 온도는 연신사의 주행안정성 및 열적 안정성을 고려하여 100~230℃가 바람직하다.And the temperature of the hot plate is preferably 100 ~ 230 ℃ in consideration of the running stability and thermal stability of the drawn yarn.

이상과 같이 처리된 연신사는 원사상태로 루프가 발현되지 않으므로 준비 및 제직 등 후공정 통과성이 우수하며, 후공정시 두 사조간 40~80%의 신장차를 발현하여 우수한 벌키성을 갖게 된다.Since the drawn yarn treated as described above does not express the loop in the yarn state, it has excellent post-process passability such as preparation and weaving, and has excellent bulkiness by expressing an elongation difference of 40 to 80% between the two yarns during the post-process.

또한, 고온연신시 결정화와 배향의 증가로 인해 섬유 비중이 증대되어 드레이프성이 향상된다.In addition, due to the increase in crystallization and orientation during high-temperature stretching, the specific gravity of the fiber is increased to improve drape.

이하, 본 발명을 실시예를 통하여 더욱 구체적으로 설명하겠는 바, 본 발명의 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. However, the present invention is not limited to the Examples.
