Description

폴리에스테르 섬유의 제조방법Method for producing polyester fiber

본 발명은 염기성 염료에 가염성인 동시에 섬유내에 알칼리에 가용성인 초미립자상의 규소화합물이 균일하게 분포되도록 하여서 감량가공후 천연섬유와 같은 외관 및 촉감을 가지도록 한 신규한 폴리에스테르 섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing a novel polyester fiber that is uniformly distributed in basic fibers with chlorine that is both soluble in basic dyes and soluble in alkali, and thus has the same appearance and feel as natural fibers after weight loss processing. .

종래의 각종 합성섬유 중, 특히 용융방사한 열가소성 섬유(폴리에스테르, 폴리아미드, 폴리올레핀 등)는 표면상태가 평활하고 합성섬유 자체의 단점들이 있어서 천연섬유에 비하여 광택, 촉감, 마찰특성, 수분흡수율 및 염색시 발색성 등이 열등하다.Among various conventional synthetic fibers, thermoplastic fibers (polyesters, polyamides, polyolefins, etc.) melt-spun, in particular, have a smooth surface and have disadvantages of synthetic fibers themselves. Inferior in color development and dyeing.

이중에서 폴리에스테르 섬유의 경우는 섬유의 표면상태를 변화시켜 이와같은 결점을 개선하고자 하는 연구가 종전부터 많이 행하여 졌고, 특히 일본에서는 규소화합물이 알칼리에 가용성인 점에 착안하여 폴리에스테르 섬유 제조시 규소화합물을 충입한 후 알칼리 금속 수산화물로 처리함으로서 미세한 요철이 섬유표면에 존재케하는 특수섬유의 제조법에 대하여 많은 연구를 하였다.In the case of polyester fiber, many studies have been conducted to improve such defects by changing the surface state of the fiber. Particularly, in Japan, the silicon compound is soluble in alkali, and the silicon in the polyester fiber manufacturing has been focused on. After charging the compound and treating with alkali metal hydroxide, many researches have been made on the manufacturing method of special fibers in which fine irregularities are present on the fiber surface.

그러나 이 경우에 있어서, 응집력이 큰 규소화합물이 잘 분산되어 있지 않고 또한 폴리에스테르 폴리머와 규소화합물 사이에 상용성이 없기 때문에 실을 제조하기가 어려웠고, 실을 제조한 후에도 강도, 신도가 약한 결점이 있으며, 염기성 염료에 대한 친화성이 없다.In this case, however, it is difficult to manufacture a yarn because a silicon compound having a large cohesion force is not dispersed well and there is no compatibility between the polyester polymer and the silicon compound, and a weak strength and elongation even after the yarn is produced. And no affinity for basic dyes.

이러한 문제점을 해결하기 위하여 본 발명자는 오랜동안 연구한 결과 규소화합물 및 아래 일반식(I), (II), (III)의 화합물을 사용하여 폴리에스테르 공중합체를 제조하면 종래의 알칼리 가용성 폴리에스테르 보다 월등히 뛰어난 분산성, 염색성, 감량율, 강도를 가지게 됨을 알게 되어 본 발명에 이르게 되었다.In order to solve this problem, the present inventors have studied for a long time to produce polyester copolymers using silicon compounds and the compounds of the following general formulas (I), (II) and (III). The present invention has been found to have excellent dispersibility, dyeing, weight loss, and strength.

즉, 폴리에스테르를 제조함에 있어 TPA 또는 DMT를 주로하는 2관능성 카르복실산 또는 그의 에스테르 형성 유도체에다 아래 일반식(I)의 화합물을 TPA 또는 DMT에 대해 0.5~5.0몰%, 바람직하게는 1.0~3.0몰% 함유시키고, 이와는 별도로 EG와 일반식(II)의 화합물을 규소화합물에 대해 0.1~0.5중량%, 아래 일반식(III)의 화합물을 규소화합물에 대해 0.1~5.0중량% 그리고 규소화합물을 DMT 또는 TPA에 대해 0.5~5.0중량%만큼 혼합하여 이들을 통상의 방법으로 중합하면 고유점도 0.5 이상, 감량을 20% 이상 및 염기성 염료에 가염성인 동시에 조업성이 월등히 폴리에스테르 공중합체를 얻을 수 있었다.That is, in preparing the polyester, the compound of the general formula (I) below 0.5 to 5.0 mol%, preferably 1.0 to the TPA or DMT, in addition to the bifunctional carboxylic acid or ester forming derivative thereof mainly comprising TPA or DMT. ~ 3.0 mol%, and separately EG and the compound of formula (II) 0.1 to 0.5% by weight of the silicon compound, the compound of formula (III) below 0.1 to 5.0% by weight of the silicon compound and the silicon compound Was prepared by mixing 0.5 to 5.0% by weight with respect to DMT or TPA and polymerizing them in a conventional manner to obtain a polyester copolymer having an intrinsic viscosity of at least 0.5, a weight loss of at least 20%, and a basic dye, and being highly soluble. .

본 발명을 더욱 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

즉, DMT와 DMT에 대해 0.5~5.0몰%의 R가 알킬인 벤젠술폰산금속염 유도체(I)과, EG와 에스테르 교환반응촉매를 투입하여 220~250℃ 온도에서 에스테르 교환반응을 실시하고, 이와는 별도로 DMT로 대해 0.5~5.0몰%의 규소화합물과 EG, 분산촉진 및 친화조제로 사용되는 (II)와 (III)의 화합물을 규소화합물에 대해 0.5~5.0중량%로 혼합하여 규소화합물의 2차 입자 크기가 0.5μ 이하인 EG 혼합 슬러리를 만들고 이들을 함께 혼합하여 폴리머에 대해 200~400ppm의 Sb2O3를 투입하여 270~290℃의 고온 및 0.6mmHg 이하의 고진공에서 증축합반응을 시켜서 고유점도 0.5 이상의 염기성염료에 가염성이며 알칼리 감량율이 20% 이상인 신규한 폴리에스테르 공중합체를 제조하고, 이를 통상의 방법으로 방사, 연신한다.That is, a transesterification reaction is carried out at 220-250 ° C. with a benzene sulfonic acid metal salt derivative (I) having 0.5-5.0 mol% of R as alkyl relative to DMT and DMT, and EG and a transesterification catalyst. 0.5 ~ 5.0 mol% of silicon compound with respect to DMT and EG, secondary particles of silicon compound by mixing 0.5 ~ 5.0% by weight of compound of (II) and (III) used as dispersing accelerator and affinity aid to silicon compound EG mixed slurry having a size of 0.5μ or less is made and mixed together, 200 ~ 400ppm Sb 2 O 3 is added to the polymer to carry out the condensation reaction at a high temperature of 270 ~ 290 ℃ and high vacuum of 0.6mmHg or less to intrinsic viscosity of 0.5 or more. A novel polyester copolymer that is salty to basic dyes and has an alkali reduction ratio of 20% or more is prepared, and is spun and stretched in a conventional manner.

본 발명에서 사용한 에스테르 교환반응 촉매는 Ca(OAc)2, Zn(OAc)2, Mn (OAc) 등으로 부터 선택한 것이다.The transesterification catalyst used in the present invention is selected from Ca (OAc) 2 , Zn (OAc) 2 , Mn (OAc) and the like.

위에서 2차 입자라고 함은 첨가되는 규소화합물(1차 입자)이 분산촉진제 및 친화조제에 의하여 분산이 된 다음에 생성된 입자를 말함.The secondary particles above refer to particles produced after the added silicon compound (primary particles) is dispersed by a dispersing accelerator and an affinity aid.

본 발명에서 사용하는 일반식(I)의 화합물을 TPA 또는 DMT에 대해 0.5몰%보다 작게 사용하면 제조되어지는 폴리에스테르의 염색성을 크게 개선시킬 수 없으며, 5.0몰% 보다 크게 사용하면 제조되어지는 폴리에스테르의 내열성 및 물성이 크게 취약하게 되어 후가공에서 많은 문제점을 나타낸다.When the compound of the formula (I) used in the present invention is used in an amount of less than 0.5 mol% with respect to TPA or DMT, the dyeability of the polyester may not be significantly improved. The heat resistance and physical properties of the ester are greatly weakened, which presents many problems in post processing.

또한 일반식(II)의 화합물을 규소화합물에 대해 0.5중량% 이하 사용하면 규소화합물을 잘 분산시키지 못하여 응집현상이 일어나 제사성 불량의 요인이 되며 5.0중량% 이상 사용하면 폴리머의 분해를 촉진시켜 중합이 지연되거나 제반 물성이 크게 저하하게 된다.In addition, if the compound of Formula (II) is used at 0.5 wt% or less with respect to the silicon compound, the silicon compound may not be dispersed well and coagulation may occur. This delay or overall physical properties are greatly reduced.

또한 (III)의 화합물을 TPA 또는 DMT에 대해 0.5중량% 이하 사용하게 되면 섬유 표면에 단위 면적당 존재하는 미립자의 갯수가 적어 천연섬유와 같은 광택 및 촉감등이 없게 되고, 5.0중량% 이상 사용하면 충입된 규소화합물의 미분산이 어려워 제사성 불량을 초래하게 된다.In addition, when the compound of (III) is used in an amount of 0.5 wt% or less with respect to TPA or DMT, the number of fine particles per unit area on the surface of the fiber is small, so that there is no gloss and feel like natural fiber, and when it is used in an amount of 5.0 wt% or more Undispersed dispersion of the silicon compound is difficult, resulting in poor rusting.

또한 본 발명에서의 폴리에스테르 공중합체를 제조할 때 인산, 아인산, 트리메틸 포스페이트, 트리스노닐페닐 포스파이트등의 인계안정제를 사용할 수 있다.Moreover, when manufacturing the polyester copolymer in this invention, phosphorus stabilizers, such as phosphoric acid, phosphorous acid, trimethyl phosphate, and trisnonylphenyl phosphite, can be used.

본 발명은 TPA, DMT법에 공히 적용할 수 있으며, 통상의 방사, 연신공정을 거쳐 필라멘트 또는 스테이플 파이버로 제조될 수 있다.The present invention can be applied to both TPA and DMT methods, and can be made of filament or staple fiber through a conventional spinning and stretching process.

본 발명에서의 폴리머의 융점은 DSC로 측정하였으며, 극한점도는 칩을 오르소 클로로페놀에 녹여 0.5중량%의 용액으로 한 후 유볼노드점도계로 25℃에서 측정하였다. 또한 알칼리 감량율은 다음과 같은 방법으로 구하였다. 필라멘트사를 합사하여 300데니어의 실을 만든 후 20게이지의 시험용 환편기를 사용하여 환편물을 만든다.Melting point of the polymer in the present invention was measured by DSC, the intrinsic viscosity was dissolved in ortho chlorophenol to 0.5% by weight of the solution was measured at 25 ℃ with a euboloid viscometer. In addition, alkali reduction rate was calculated | required by the following method. The filament yarns are plyed together to make 300 denier yarns, and then circular knits are made using a 20-gauge test circular knitting machine.

순도 99% 이상의 수산화나트륨과 순수를 사용하여 4중량%의 수산화나트륨 수용액을 제조한 후, 욕비 50:1로 100℃에서 1시간 처리한 후 수세하고, 0.5중량%의 초산수용액으로 중화한 후 다시 수세하고 건조한다. 건조 전후의 중량차이로 감량율을 구하였다.4% by weight of aqueous sodium hydroxide solution was prepared using sodium hydroxide and pure water of 99% or higher purity, treated with a bath ratio of 50: 1 at 100 ° C for 1 hour, washed with water, neutralized with 0.5% by weight of acetic acid solution, and then again. Wash and dry. The weight loss ratio was determined by the difference in weight before and after drying.

본 발명은 방사조업성이 우수하였으며, 제조된 폴리에스테르 섬유는 발색성, 광택 및 촉감이 양호하였으며 본 발명으로 제조된 폴리머는 극한점도가 0.5 이상, DEG가 1.5~2.0%로서 우수한 물성을 나타내었다.The present invention was excellent in spinning operation, the produced polyester fiber was good in color development, gloss and feel, and the polymer produced by the present invention exhibited excellent physical properties such as intrinsic viscosity of 0.5 or more and DEG of 1.5 to 2.0%.
