Description
본 발명은 폴리에스테르 이형단면사에 관한 것이다. 보다 구체적으로, 본 발명은 친환경적 알칼리 감량을 통하여 마이크로슬릿의 형성을 용이하게 하고, 그 결과 기존의 원형단면 폴리에스터 원사에 비해 부드러운 감촉과 우수한 흡습성능을 갖는 폴리에스테르 이형단면사에 관한 것이다. 본 발명은 또한 상기 폴리에스테르 이형단면사를 제조하는 방법도 포함한다.
The present invention relates to a polyester modified cross-section yarn. More particularly, the present invention relates to a polyester release cross-section yarn which facilitates the formation of micro slits through an environmentally-friendly alkali reduction and, as a result, has a soft feel and excellent hygroscopicity compared to conventional circular cross-section polyester yarns. The present invention also encompasses a method for producing said polyester modified cross-section yarn.
폴리에스테르 원사는 다양한 목적으로 개발되어 사용되고 있지만, 그 중의 하나는 종래의 레이온 원사 대용으로 개발되고 있다는 것이다. Polyester yarns have been developed and used for various purposes, but one of them is being developed as a substitute for conventional rayon yarn.
일반적인 레이온 섬유는 목재 또는 무명의 부스러기 등을 적당한 화학적 방법으로 처리하여 순수한 섬유소로 이루어진 펄프를 만들고, 이를 화학적으로 용해한 다음 다시 섬유상으로 응고시켜 제조한다. 레이온 원사는 감촉이 부드러운 소프트 촉감, 흡습성, 발색성 등이 우수하지만, 내수성이 크게 떨어지고, 탄성이 적으며, 강도, 형태안정성, 및 품질의 균일성 확보가 어렵고, 가격이 비싼 단점이 있다.Typical rayon fibers are made by treating wood or cotton waste with suitable chemical methods to make pulp of pure cellulose, chemically dissolving it, and then solidifying it in a fibrous form. Rayon yarn is excellent in soft touch feeling, hygroscopicity, colorability, etc., but has a disadvantage in that water resistance is greatly lowered, elasticity is low, strength, form stability, and uniformity of quality are difficult to obtain and the price is high.
이에 반해 폴리에스테르 섬유는 소프트 촉감, 흡습성, 자연적 느낌 등이 열등하지만, 강도가 높고, 염가공성 및 형태안정성이 우수하며, 가격이 저렴한 장점이 있다. 따라서 폴리에스테르의 장점을 살려서 레이온 섬유에 근접한 원사를 개발하고자 하는 많은 연구가 진행되어 왔다. 폴리에스테르 수지를 개질하거나 형상을 변경함으로써 레이온 섬유의 단점을 보완하고 폴리에스테르의 장점을 살린 폴리에스테르 원사를 개발하고자 한 것이다. On the other hand, polyester fibers are inferior in soft feel, hygroscopicity, and natural feeling, but they are high in strength, excellent in sinterability and shape stability, and low in price. Therefore, many researches have been conducted to develop a yarn which is close to rayon fiber by utilizing the advantages of polyester. The present inventors have attempted to develop a polyester yarn that can compensate for the disadvantages of the rayon fibers by modifying or changing the shape of the polyester resin and taking advantage of the advantages of the polyester.
합성섬유인 폴리에스테르가 레이온과 유사한 성능을 보유하기 위한 기술은 하기와 같이 크게 두 가지로 설명된다. 하나는 폴리에스테르 수지에 첨가제를 투입하는 방법이다. 대한민국특허출원 제2005-0019424호는 ‘고광택 원사 제조용 폴리에스테르 조성물 및 그로부터 제조되는 고광택원사’에 관한 발명으로, 황산바륨 입자와 폴리에스테르 고상중합칩을 혼합한 마스터배치법을 이용하여 드레이프(drape)성을 높인 폴리에스테르를 개시한다. 그러나, 이는 마스터배치법에 의한 폴리에스테르 내 황산바륨의 분산성 저하로 인하여 방사시 팩(pack) 압력이 상승하고, 레이온의 광택특성의 개선이 어려우며, 레이온의 소프트한 촉감 및 흡습성 개선도 어렵다.Techniques for the synthetic fiber polyester to possess similar performance to rayon are described in two broadly as follows. One method is to add additives to the polyester resin. Korean Patent Application No. 2005-0019424 relates to a polyester composition for high-gloss yarn production and a high-gloss yarn produced therefrom. The master batch method in which barium sulfate particles and polyester solid-state polymer chips are mixed is used to produce drape- Is increased. However, it is difficult to improve the gloss characteristics of the rayon, and it is also difficult to improve the soft touch of the rayon and the hygroscopicity due to the increase of the pack pressure during spinning due to the lowering of the dispersibility of barium sulfate in the polyester by the master batch method.
레이온과 유사한 성능을 보유하기 위한 다른 기술로는 이형단면을 갖는 원사를 제조하는 방법이다. 이형단면사를 제조하는 방법은 크게 방사구금을 이형화하거나 이성분 방사법을 통해 일성분을 용출하는 방법으로 구분할 수 있다. 이형단면사는 특히 심색화나 흡한속건성 등의 기능향상을 위해 다수 사용되고 있다. Another technique for retaining similar performance to rayon is to produce yarns with a modified cross-section. The method of producing the modified cross section yarn can be roughly divided into a method of releasing the spinneret or a method of eluting one component by the binary spinning method. The modified cross section yarns are mainly used for improvement of functions such as deepening of color and sweat fastness.
대한민국특허출원 제2006-0129230호는 ‘이형단면 폴리에스테르 섬유 및 그 제조방법’에 관한 발명으로, 설포네이트 금속염과 폴리에옥시알킬렌 에스테르 화합물을 이용하여 폴리에스테르 공중합물을 제조한 후, 감량가공을 통해 마이크로슬릿을 형성시켜 레이온과 유사한 촉감 및 외관을 갖는 폴리에스테르 이형단면사 제조기술을 개시한다. 그러나 이는 촉감 개선은 우수하지만, 중합공정에서 금속염 화합물이 응집되어 섬유제조시 염색줄이 발생하고, 마이크로슬릿 형성이 용이하지 않으며, 알칼리 감량시에 환경법상 산업폐기물에 해당하는 다량의 폴리에스테르 공중합물 올리고머와 안티몬과 같은 중금속을 발생시킨다. 상업 폐기물에 해당하는 폴리에스테르 공중합물과 안티몬과 같은 중금속은 폐수처리 비용을 증가시키고 환경오염을 유발시킨다. Korean Patent Application No. 2006-0129230 is an invention related to "modified cross-section polyester fiber and method of manufacturing the same", wherein a polyester copolymer is produced using a sulfonate metal salt and a polyoxyalkylene ester compound, Discloses a technique for producing a polyester modified cross-section yarn having a tactile feel and an appearance similar to rayon by forming a micro slit. However, the improvement of the feel is excellent, but the metal salt compound is aggregated in the polymerization process, and staining occurs in the production of fiber, micro slit formation is not easy, and when the alkali is reduced, a large amount of polyester copolymer It generates heavy metals such as oligomers and antimony. Polyester copolymers corresponding to commercial waste and heavy metals such as antimony increase the cost of wastewater treatment and cause environmental pollution.
본 발명자는 상기와 같은 종래의 문제점을 해결하여, 알칼리 감량시에도 친환경적인 방법으로 감량할 수 있고, 레이온과 유사한 부드러운 촉감과 흡습성을 갖는 본 발명의 이형단면 폴리에스테르 복합섬유소재를 개발하기에 이른 것이다.
DISCLOSURE OF THE INVENTION The present inventors have made efforts to develop a polyester cross-linked composite fiber material of the present invention having a soft touch and hygroscopicity similar to rayon, which can be reduced by an environmentally friendly method even in the case of reducing the amount of alkali, will be.

상기 표 1의 결과로부터 알 수 있는 바와 같이, 알칼리 함량이 증가함에 따라 PLA의 감량율이 증가하는 것을 알 수 있으며, 용출된 PLA에 의해 PET 표면에 마이크로슬릿이 형성되는 것을 알 수 있다. 제2도는 실시예 1A-1E에서 용출된 PLA에 의해 PET 표면에 마이크로슬릿이 형성된 것을 나타내기 위한 현미경 사진이다. 표 1에서와 같이 감량율이 12 % 이상인 실시에 1C-1D 원사에서 제작된 직물들은 소프트 촉감이 매우 우수하였으나, 원사강도 결과에서 볼 수 있듯이 본 발명의 감량율 범위를 벗어날 경우(과감량시), 즉 실시예 1E인 경우, PET 섬유에 손상에 따라 원사의 강도가 지나치게 낮아지게 된다. 결과적으로 실시예 1C-1D 만이 본 발명의 바람직한 범위라 할 수 있다.
As can be seen from the results of Table 1, it can be seen that the weight loss rate of PLA increases with the increase of the alkali content, and micro-slits are formed on the PET surface by the eluted PLA. FIG. 2 is a photomicrograph showing the formation of micro-slits on the PET surface by the PLA eluted in Examples 1A-1E. As shown in Table 1, the fabrics made from the 1C-1D yarn exhibited excellent soft touch feeling when the weight loss rate was 12% or more. However, as can be seen from the yarn strength results, when the weight loss rate was out of the range of the present invention , That is, in the case of Example 1E, the strength of the yarn becomes excessively low due to damage to the PET fiber. As a result, only Example 1C-1D is the preferred range of the present invention.

PET 수지 95 wt%에 PLA 5 wt %를 블렌딩하여 이형단면 방사구금을 통해 원사를 제조하였다. 실시예 1에서의 결과에서 원사강도 및 직물촉감이 우수한 조건인 알칼리 함량 10 g/L 조건에서 감량시간에 따라 원사강도 및 마이크로 슬릿의 형성 정도를 평가하였으며 또한 이를 직물로 제작한 후 물성을 측정하였다. 시험조건 및 물성결과를 표 2에 나타내었다.
5 wt% of PLA was blended with 95 wt% of PET resin, and yarn was prepared by spinning spinning. From the results in Example 1, the yarn strength and the formation of micro slits were evaluated according to the weight loss time under the conditions of an alkali content of 10 g / L, which is an excellent condition of the yarn strength and texture of the fabric, and the fabric properties were measured . Test conditions and physical properties are shown in Table 2.

상기 표 2의 결과로부터 알 수 있는 바와 같이, 알칼리 감량 시간이 증가함에 따라 PLA의 감량율이 증가하는 것을 알 수 있으며, 용출된 PLA에 의해 PET 섬유 표면에 마이크로슬릿이 형성되는 것을 알 수 있다. 표 2에서와 같이 감량율이 11 % 이상인 실시예 2C-2E에서 제작된 직물들은 소프트 촉감이 매우 우수하였다.
As can be seen from the results in Table 2, it can be seen that the weight loss rate of PLA increases with increasing alkali reduction time, and micro-slits are formed on the surface of PET fibers by the eluted PLA. As shown in Table 2, the fabrics produced in Example 2C-2E having a weight loss rate of 11% or more had excellent soft touch.

The yarn was prepared in the same manner as in Example 1C except that a polyester copolymer resin was used in place of PLA. The amount of oligomers produced by antimony and polyester copolymer was measured to be 578 ppm when the alkali was reduced. The corresponding amounts of antimony and polyester copolymer oligomers produced during the alkali reduction were measured for Examples 1C and 2C and found to be 0 ppm.
