Abstract
Description
제1도는 본 발명에 의해 제조된 섬유의 측면 확대사진.1 is an enlarged side view of the fiber produced by the present invention.
제2도는 본 발명에 의해 제조된 섬유의 단면 확대사진.Figure 2 is an enlarged cross-sectional picture of the fiber produced by the present invention.
본 발명은 세라믹 무기미립자가 섬유에 분포되게 한 다음 알카리처리함으로 중공단면인 섬유표면에 미세다공이 무수히 많은 폴리에스테르섬유의 제조방법으로, 일반 흡수성 폴리에스테르 섬유보다 흡수성이 영구히 지속되며 미세다공의 크기가 크고 물리적인 성질이 우수한 고흡수성 및 고드레이프성 폴리에스테르 섬유의 제조방법이다.The present invention is a method for producing a polyester fiber with a large number of micropores on the fiber surface of the hollow cross-section by allowing the ceramic inorganic fine particles to be distributed in the fiber and then subjected to alkali treatment. It is a method for producing superabsorbent and high-drape polyester fibers having large and excellent physical properties.
일반적으로 폴리에스테르 섬유는 높은 강도, 내약품성 등 우수한 성질을 갖고 있지만, 결정성이 높고 소수성 섬유인 동시에 화학적 반응성기를 갖고 있지 못하므로 대전성, 흡수성, 염색성이 떨어진다.In general, polyester fibers have excellent properties such as high strength and chemical resistance, but they have high crystallinity, are hydrophobic fibers, and do not have chemically reactive groups.
이를 개선하기 위하여 예를 들면 합성섬유에 흡수, 흡수성을 부여하는 방법으로는 대한민국 특허공고 제88-1642호, 89-1839호와 같이 폴리에스테르 주성분에 알칼리에 용해되는 유기화합물을 혼합하여 미세다공을 형성하는 방법과 또 다른 제조방법으로는 대한민국 특허공고 제86-397호, 86-1224호, 87-593호와 같이 무기미립자를 첨가한 다음 알카리 수용액으로 처리하여 폴리에스테르내에 무기미립자를 용해, 추출함으로 섬유의 표면과 내부의 중공을 관통하여 흡수성을 발휘하도록 하는 방법이 알려진 바 있으나, 유기화학물의 혼합방식은 만족스러운 흡수기능을 얻으려면 심각한 물성저하를 초래하는 단점이 있고, 무기미립자를 첨가하는 방법은 방사작업성이 불량하고, 팩압의 상승으로 인한 팩 라이프가 짧은 문제점이 있다.In order to improve this, for example, as a method of absorbing and absorbing synthetic fibers, fine pores may be mixed by mixing organic compounds dissolved in alkali with polyester main components such as Korean Patent Publication Nos. 88-1642 and 89-1839. As a method of forming and another manufacturing method, inorganic fine particles are added as in Korean Patent Publication Nos. 86-397, 86-1224, 87-593, and then treated with an aqueous alkali solution to dissolve and extract the inorganic fine particles in polyester. As a result, there has been known a method of exerting absorbency through the hollow of the surface and the inside of the fiber, but the mixing method of organic chemicals has a disadvantage of causing severe physical property deterioration in order to obtain a satisfactory absorption function. The method has a problem in that the spin workability is poor and the pack life is short due to the increase in the pack pressure.
본 발명은 이러한 종래 기술의 문제점을 해결한 것으로서, 본 발명의 목적은 무기미립자와 이산화티탄을 함께 첨가한 다음 아카리 처리하므로써 섬유표면에 미세다공을 무수히 형성시켜 흡수성 및 드레이프성이 향상된 폴리에스테르 섬유를 제공하는 데에 있다.The present invention solves the problems of the prior art, an object of the present invention is to add a fine particle and titanium dioxide together, and then akari treatment to form a myriad of micropores on the fiber surface to improve the water absorption and drape polyester fiber To provide.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 흡수성 폴리에스테르 섬유를 제조함에 있어서, 폴리에스테르 폴리머에 다음 일반식(I)로 표시되는 무기미립자와 이산화티탄을 중합공정이나 방사공정중에 첨가하여 섬유를 제조한 다음 알카리 수용액으로 감량처리하는 것을 특징으로 하는 흡수성 및 드레이프성이 우수한 폴리에스테르 섬유의 제조방법이다.In the present invention, in the preparation of absorbent polyester fibers, the inorganic polymer and titanium dioxide represented by the following general formula (I) are added to the polyester polymer during the polymerization process or the spinning process to prepare the fibers, and then weight loss treatment with an aqueous alkali solution. It is a manufacturing method of the polyester fiber excellent in the water absorption and the drape characterized by the above-mentioned.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명은 상기 일반식(I)로 표시되는 무기미립자와 이산화티탄을 통상의 폴리에스테르 중합공정 중 에스테르화 반응 말기에 첨가하거나 용융방사시 칩으로 브렌딩하면 되는 바, 상기 일반식(I)로 표시되는 무기미립자의 첨가량은 폴리에스테르에 대하여 0.1~25중량%가 정당한데 만일 첨가량이 0.1중량%미만이면 만족할 만한 물성을 얻기 어렵고 25중량%를 초과하면 방사, 연신시 작업성 불량이 발생한다.In the present invention, the inorganic fine particles and titanium dioxide represented by the general formula (I) may be added at the end of the esterification reaction in a conventional polyester polymerization process or may be blended into chips during melt spinning. The amount of inorganic fine particles added is just 0.1 to 25% by weight with respect to polyester. If the amount is less than 0.1% by weight, it is difficult to obtain satisfactory physical properties. If it exceeds 25% by weight, poor workability occurs during spinning and stretching.
이러한 무기미립자의 입자크기는 입경이 0.3~2㎛인 것을 사용하는 것이 바람직한 바, 입경이 0.3㎛ 미만일 경우 본 발명에서 목적하는 만큼의 충분한 효과가 발현되지 않으며 2㎛을 초과할 경우에는 물성저하의 문제점이 있다.The particle size of such inorganic fine particles is preferably used with a particle size of 0.3 ~ 2㎛ bar, when the particle size is less than 0.3㎛ does not express a sufficient effect as desired in the present invention, when the particle size exceeds 2㎛ There is a problem.
본 발명에 사용할 수 있는 무기미립자의 구체적인 예를 들면 활산바륨, 활산마그네슘, 황산칼슘 등이 있다.Specific examples of the inorganic fine particles that can be used in the present invention include barium active, magnesium active, calcium sulfate and the like.
또한, 이산화티탄은 알카리 처리시 무기미립자의 용출을 용이하게 하기 위하여 첨가하는 바, 이때 그 첨가량은 폴리에스테르에 대하여 0.01~5중량%가 적당하다. 만일 첨가량이 0.01중량%미만이면 표면에 미세다공을 형성하지 못하는 문제가 있고 5중량%를 초과하면 팩 라이프가 짧아지는 문제점이 있다.In addition, titanium dioxide is added in order to facilitate the elution of the inorganic fine particles during the alkali treatment, in which the amount is preferably 0.01 to 5% by weight relative to the polyester. If the amount is less than 0.01% by weight, there is a problem in that the micropores cannot be formed on the surface, and if the amount exceeds 5% by weight, the pack life is shortened.
이렇게 제조된 칩을 통상의 방법으로 방사, 연신하여 섬유를 제조한 다음 알카리 수용액에서 감량을 하는데 감량율 15~30%가 적당하다.The prepared chip is spun and stretched in a conventional manner to prepare fibers, and then to reduce the weight in an aqueous alkali solution.
만일 감량율이 15% 미만이면 충분한 흡수성을 발현시키지 못하며, 30%를 초과하면 강도저하가 야기된다.If the reduction rate is less than 15%, sufficient absorbency is not expressed, and if the reduction rate is greater than 30%, strength decrease is caused.
본 발명으로 제조된 섬유는 방사함에 있어서 중공타입을 갖는 섬유를 제조하는 것이 좋은 바, 종공의 형태는 다양한 형태를 가질 수 있으며, 여러 형태의 섬유에서도 동일한 효과를 얻을 수 있다.The fiber produced by the present invention is good to produce a fiber having a hollow type in spinning, the shape of the longitudinal hole may have a variety of forms, the same effect can be obtained in various types of fibers.
이하, 본 발명을 실시예를 통하여 더욱 구체적으로 설명하겠는 바, 실시예에 의해 본 발명이 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited by Examples.
