인조모발용 폴리에스테르사의 제조방법Manufacturing method of polyester yarn for artificial hair
[발명의 상세한 설명]Detailed description of the invention
[발명의 목적][Purpose of invention]
[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical field to which the invention belongs and the prior art in that field]
본 발명은 인조모발로 사용되는 폴리에스테르사의 제조방법에 관한 것이다. 더욱 구체적으로 설명하면 천연모발과 흡사하게 번쩍거림이 없으며 균제도(Evenness)가 우수한 인조모발용 폴리에스테르사의 제조방법에 관한 것이다.The present invention relates to a method for producing polyester yarn used as artificial hair. More specifically, the present invention relates to a method for preparing polyester yarn for artificial hair, which has no glazing similar to natural hair and has excellent evenness.
폴리에스테르사는 인조모발로 많이 사용되어온 폴리비닐 클로라이드사에 비하여 고강력이고 열세트내구성이 우수한 장점이 있는 반면에 번쩍이는 광택을 가지는 단점이 있다.Polyester yarns have the advantages of high strength and excellent heat set durability compared to polyvinyl chloride yarns, which have been widely used as artificial hairs, but have a disadvantage of having a shiny luster.
이와 같은 번쩍이는 광택을 감소시켜서 천연모발과 흡사하게 하기 위하여 폴리에스테르사의 표면에 광선을 난반사시키는 미세기공들을 형성시키는 기술들이 개발된 바 있다.In order to reduce the shiny luster and resemble natural hair, techniques have been developed to form micropores that diffusely reflect light rays on the surface of polyester yarns.
즉, 일본특개소 63-211311에 의하면 표면미세공형성제로 인화합물과알카리토금속화합물을 사용하고 있고, 일본특개평 5-086505와 한국특허공고 96-11597호는 이산화 규소미립자를 사용하여 감량처리함으로서 난반사에 의한 소광효과로 번쩍거림을 방지하도록 한 것이다.That is, according to Japanese Patent Application Laid-Open No. 63-211311, phosphorus compounds and alkaline earth metal compounds are used as surface micropore-forming agents, and Japanese Patent Application Laid-Open No. 5-086505 and Korean Patent Publication No. 96-11597 use weight loss treatment using silicon dioxide fine particles. It is to prevent glare by the quenching effect of diffuse reflection.
그러나 상기 방법들은 폴리머내에 미립자를 균일하게 분산시키기 어렵기 때문에 제사후에 섬유의 균제도가 저하되고 동시에 섬유물성의 불균일을 초래하였다.However, the above methods are difficult to uniformly disperse the fine particles in the polymer, so the uniformity of the fiber is reduced after the sacrifice, and at the same time, the uniformity of the fiber properties is caused.
[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]
본 발명은 저점도의 액상폴리에스테르를 분산제로 사용하여 폴리에스테르 폴리머내에 이산화규소 미립자가 균일하게 분산되도록하여서 번쩍거림이 방지되면서 균제도가 우수한 천영모발에 근사한 인조가발용 폴리에스테르사의 제조방법을 제공하는데 그 목적이 있다.The present invention uses a low-viscosity liquid polyester as a dispersant to uniformly disperse the silicon dioxide fine particles in the polyester polymer to provide a method of manufacturing a polyester wig for artificial wigs close to cheonyoung hair having excellent uniformity while preventing glare. The purpose is.
[발명의 구성 및 작용][Configuration and Function of Invention]
본 발명은 폴리에스테르를 용융방사, 연시하여 폴리에스테르사를 제조함에 있어서, 저점도 액상 폴리에스테르를 이산화규소마스터배치 칩에 대하여 무게비로 0.05 ∼ 2배 혼합 분산시킨 후 이 혼합물을 폴리에스테르에 첨가시키되 순수한 이산화규소(SiO2)미립자를 폴리에스테르의 중량에 대하여 2 ∼ 10 중량% 첨가시키는 것을 특징으로 하는 균제도가 우수한 인조모발용 폴리에스테르사의 제조방법이다.In the present invention, in the manufacture of polyester yarns by melt spinning and stretching polyester, low viscosity liquid polyester is dispersed in a weight ratio of 0.05 to 2 times with respect to the silicon dioxide master batch chip, and then the mixture is added to the polyester. Pure silicon dioxide (SiO 2 ) fine particles 2 to 10% by weight based on the weight of the polyester is characterized in that the uniformity is excellent manufacturing method of polyester yarn for artificial hair.
본 발명에서 사용하는 저점도액상폴리에스테르는 액체상태로 존재하는 액상폴리에스테르로서 아디프산, 세바신산, 아젤라인산, 글루탐산, 테레프탈산, 이소프탈산, 프탈산 및 프탈산 무수물둥과 같은 지방족 또는 방향족 디카르복실산과 에틸렌글리콜, 프로필렌글리콜, 부틸렌글리콜등과 같은 2가 알콜과의 증축합물이며, 분자량이 500 ∼ 3,000인 것이 적당하다. 액상폴리에스테르의 점도는 통상적으로 분자의 구조와 분자량에 의하여 좌우되는바, 본 발명에서 사용되는 것은 25℃에서 측정한 값이 5∼50 포아즈이고, 이때의 분자량은 500∼3,000이다.The low viscosity liquid polyester used in the present invention is a liquid polyester present in a liquid state, and is an aliphatic or aromatic dicarboxyl such as adipic acid, sebacic acid, azelaic acid, glutamic acid, terephthalic acid, isophthalic acid, phthalic acid and phthalic anhydride. It is a condensation product of an acid and dihydric alcohols, such as ethylene glycol, propylene glycol, butylene glycol, etc., and it is suitable that the molecular weight is 500-3,000. Since the viscosity of a liquid polyester is normally dependent on the structure and molecular weight of a molecule | numerator, the value used at this invention is 5-50 poises measured at 25 degreeC, and the molecular weight at this time is 500-3,000.
이와 같은 저점도액상폴리에스테르는 일종의 가소제로서 홀리에스테르와의 상용성이 우수하고 액상이므로 이산화규소입자를 운반하여 폴리에스테르의 내부에 골고루 침투시키기 때문에 이산화규소입자의 분산성을 개선시키게 되는 것이다.Such a low viscosity liquid polyester is a kind of plasticizer, which is excellent in compatibility with the holly ester and is a liquid, so that the silicon dioxide particles are transported evenly to the inside of the polyester to improve the dispersibility of the silicon dioxide particles.
이때 분자량이 500미만인 것을 사용하면 이산화규소의 분산성은 양호하나 칩의 점도 저하로 인하여 섬유의 강도 저하를 일으키며, 3,000을 초과할 경우에는 이산화규소 입자의 분산성이 불량하여 섬유의 강도저하 및 균제도이 불량을 초래한다. 또한 저점도 액상폴리에스테르의 첨가량이 순수한 이산화규소 입자에 대하여 무게비로 0.05배 미만일 경우에는 이산화규소 마스터 배치 칩이 저점도액상폴리에스테르에 충분히 분산되지 않게 되어 방사, 연신등의 제사공정 후 섬유의 균제도가 불량하게 되며, 2배를 초과하였을 경우에는 분산성은 양호하나 칩의 점도저하로 인한 제사 공정 후의 섬유의 강도저하가 심하여 인조모발용 섬유로서의 물성을 만족시키지 못한다. 한편 본 발명에서 사용하는 이산화규소는 폴리에스테르에 비하여 2 ∼ 10중량% 첨가되도록 사용하는 것이 바람직한데, 2중량%미만으로 사용할 경우에는 알칼리 감량후에 이산화규소입자에 의한 소광(消光)효과가 충분하지 못하고, 10중량%를 초과할 경우에는 용융압출시 팩내의 여과층에 걸려 팩압을 상승시키거나 여과층을 손상시켜 팩압을 불안정하게 함으로서 방사성을 오히려 나쁘게 하여 섬유물성의 불균일 및 균제도가 불량해지는 원인이 된다.If the molecular weight is less than 500, the dispersibility of silicon dioxide is good, but the strength of fiber is lowered due to the decrease of the viscosity of the chip. If it exceeds 3,000, the dispersibility of silicon dioxide particles is poor and the strength and uniformity of the fiber are poor. Brings about. In addition, when the addition amount of the low viscosity liquid polyester is less than 0.05 times by weight relative to the pure silicon dioxide particles, the silicon dioxide master batch chip is not sufficiently dispersed in the low viscosity liquid phase polyester, and the uniformity of the fiber after the weaving process such as spinning and drawing When it exceeds 2 times, the dispersibility is good, but the strength of the fiber after the weaving process due to the decrease in the viscosity of the chip is severe, and the physical properties of the fiber for artificial hair are not satisfied. On the other hand, the silicon dioxide used in the present invention is preferably used so as to add 2 to 10% by weight compared to the polyester, when less than 2% by weight is not sufficient for the matting effect by the silicon dioxide particles after alkali reduction. If it is more than 10% by weight, the melt pressure extrudes the filter layer in the pack and increases the pack pressure or damages the filter layer, thereby destabilizing the pack pressure, thereby making the radioactivity worse, resulting in poor fiber uniformity and uniformity. do.

[균제도 평가][Evaluation of fungi]
제조한 모노필라멘트사를 추별로 랜덤하게 5개 취하여 섬유의 굵기를 마이크로미터를 사용하여 각 시료별로 10미터 이상 간격으로 10회 이상 실측하여 그 평균값을 섬유 직경으로 하였다. 균제도 평가는 섬유직경의 평균값에 대한 실측값들의 편차범위를 백분율로 표시하며, 그 값이 2%미만인 경우 양호, 2%이상 3%미만이면 보통, 3%이상인 경우 불량으로 판정하였다.Five monofilament yarns were randomly taken by weight, and the thickness of the fibers was measured 10 times or more at intervals of 10 meters or more for each sample using a micrometer, and the average value was made as the fiber diameter. The homogeneity evaluation indicates the range of deviation of the measured values with respect to the average value of the fiber diameter as a percentage, and when the value is less than 2%, it is good;
※ 비교예 3의 경우 저점도 액상 폴리에스테르의 양이 너무 많아 칩이 전체적으로 저점도가 되어 강도가 충분하지 못하므로 불량으로 판정하고, 비교예 4의 경우 이산화규고의 첨가량이 충분하지 못해서 소광효과가 불량하므로 불량으로 판정하였다.※ In case of Comparative Example 3, the amount of low-viscosity liquid polyester is so large that the chip is low in overall viscosity and the strength is not sufficient, and in Comparative Example 4, the addition amount of silicon dioxide is not enough, so that the matting effect Since it was bad, it was determined to be bad.
