Description
본 발명은 제전성능이 우수하면서도 일반 폴리에스터섬유의 장점과 우수한 제전성능을 갖는 폴리에스터 제전사의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester electrostatic yarn having excellent antistatic performance but having the advantages of the general polyester fiber and excellent antistatic performance.
폴리에스터섬유는 내열성, 내약품성, 강신도, 결정성, 굴곡강도 등의 물성이 우수하여 의류용으로 크게 각광을 받고 있지만 저온, 저습할때 마찰에 의한 정전기의 발생으로 먼지들을 흡착, 오염이 쉽게 되고 착용자에게 쇼크나 불쾌감을 주게 되는 문제점이 있다.Polyester fiber is attracting much attention for clothing because it has excellent physical properties such as heat resistance, chemical resistance, elongation, crystallinity, and flexural strength, but it is easy to adsorb and pollute dust due to the generation of static electricity by friction at low temperature and low humidity. There is a problem that gives the wearer shock or discomfort.
이러한 정전기 문제를 해결하기 위한 방법으로서 폴리옥시알킬렌글리콜을 블록공중합시 폴리알킬렌글리콜의 양말단을 카르복실기나 아민기로 변성시켜 폴리아미드블록공중합체로 만든 폴리알킬렌에테르아미드를 대전방지제로 사용하는 기술이 일본 특허공보 소화 44-16178호 및 동 44-7713호에 제안되어 있고 블록폴리알킬렌에테르아미드를 폴리에스터 내부에 분산시키는 기술이 일본 특허공보 소화 48-10380호 및 50-107206호에, 블록폴리알킬렌에테르아미드와 유기전해질을 사용하는 기술이 동 45-17547호에 소개되어 있다.As a method for solving the electrostatic problem, when polyoxyalkylene glycol is block copolymerized, polyalkylene etheramide made of polyamide block copolymer by modifying the sock end of polyalkylene glycol with a carboxyl group or an amine group is used as an antistatic agent. The technique is proposed in Japanese Patent Laid-Open Nos. 44-16178 and 44-7713, and the technique of dispersing block polyalkylene etheramide in a polyester is disclosed in Japanese Patent Laid-Open Nos. 48-10380 and 50-107206, Techniques for using block polyalkylene etheramides and organic electrolytes are described in US Pat. No. 45-17547.
그러나 이들 방법은 통상의 용융중합법으로는 충분한 중합도를 얻기가 어려운 단점이 있다.However, these methods have a disadvantage in that it is difficult to obtain a sufficient degree of polymerization by conventional melt polymerization.
한편, 폴리에스터에 알칼리금속염을 배합하여 사용하는 일본 공개특허공보 소화 52-66236호와 52-131443호는 대전방지성능이 미흡하고 염색공정후나 또는 세탁후 제전성능이 떨어지는 단점이 있다.On the other hand, Japanese Patent Laid-Open Nos. 52-66236 and 52-131443, which use an alkali metal salt in combination with polyester, have disadvantages of insufficient antistatic performance and poor antistatic performance after a dyeing process or after washing.
본 발명은 이러한 문제점을 해결한 것으로 보다 상세히 설명하면 다음과 같다.The present invention solves this problem and described in more detail as follows.
본 발명은 폴리에스터에 공중합성분을 첨가하여 제전성을 부여하는 폴리에스터 제전사의 제조방법에 있어서, 공지의 알킬술폰산금속염 및 폴리알킬렌에테르아미드 또는 폴리옥시알킬렌글리콜과 함께 아래의 화합물(1)을 투입하여 공중합시키는 것을 특징으로 하는 폴리에스터 제전사의 제조방법에 관한 것이다.The present invention provides a method for producing a polyester electrostatic yarn by adding a copolymerization component to the polyester to impart antistatic properties, the following compounds (1) together with a known alkyl sulfonate metal salt and polyalkylene etheramide or polyoxyalkylene glycol It relates to a method for producing a polyester entrepreneur, characterized in that the copolymerization by adding).
종래에는 제전성을 부여하기 위한 공중합 성분으로 폴리옥시알킬렌글리콜 또는 폴리알킬렌에테르아민 구조를 갖는 성분과 아래 식(2)와 같은 알킬술폰산금속염을 투입하여 공중합시키는 방법이 주로 사용되어 왔다.Conventionally, a method of copolymerizing a component having a polyoxyalkylene glycol or polyalkylene etheramine structure with an alkylsulfonic acid metal salt such as the following formula (2) as a copolymerization component for imparting antistatic properties has been mainly used.
R2: C3∼C25인 알킬기 또는 C7∼C30인 아릴기R 2 : C 3 -C 25 alkyl group or C 7 -C 30 aryl group
M : Li, K, NaM: Li, K, Na
그러나, 본 발명자들은 제전성을 향상시키기 위해 연구한 결과, 비교적 선상 구조(LINEAR)적인 알킬술폰산금속염보다 벌키한 구조를 갖는 (1)의 화합물을 함께 사용하는 것이 제전성을 향상시키는데 유리함을 알게 되었다.However, the present inventors have studied to improve the antistatic property, and found that it is advantageous to use the compound of (1) having a bulkier structure than the alkyl sulfonate salt having a relatively linear structure (LINEAR). .
본 발명에서 사용하는 (1)의 화합물은 입체구조를 가지며 4개의 말단에 카르복시기를 가지는 것이다.The compound of (1) used in the present invention has a steric structure and a carboxyl group at four terminals.
본 발명에서는 (1) 화합물과 식(2)의 알킬술폰산염과의 중량비를 1 : 1∼1 : 20으로 하고 두 화합물의 함량을 최종 폴리에스터 대비 0.01∼2중량% 첨가하도록 한다.In the present invention, the weight ratio of the compound (1) and the alkyl sulfonate of formula (2) is 1: 1 to 1:20, and the content of the two compounds is added to 0.01 to 2% by weight relative to the final polyester.
첨가량이 0.01중량% 미만이면 중합물의 점도가 낮아지며, 2중량%를 넘으면 중합물의 점도가 지나치게 높아지고 폴리에스터의 결정성을 심하게 억제하므로 좋지 않다.If the added amount is less than 0.01% by weight, the viscosity of the polymer is lowered. If it is more than 2% by weight, the viscosity of the polymer is too high and the crystallinity of the polyester is severely suppressed.
또한, 본 발명에서 사용하는 폴리알킬렌에테르아민 구조를 갖는 화합물은 아래 식(3)의 화합물이다.In addition, the compound which has a polyalkylene ether amine structure used by this invention is a compound of following formula (3).
R3: C1∼C13인 알킬기 또는 HR 3 : C 1 -C 13 alkyl group or H
R4: C2∼C16인 알킬렌기R 4 : alkylene group having 2 to 16 carbon atoms
R5: H 또는 NH2 R 5 : H or NH 2
n : 20∼150의 정수n: integer of 20 to 150
폴리옥시알킬렌글리콜 또는 상기 식(3)의 화합물의 첨가량이 0.01중량% 미만이면 제전성의 개선효과가 미약하고 2중량%를 넘으면 사의 고유물성이 저하되는 문제점이 발생하므로 적정한 첨가량은 0.01중량%∼2중량%이다.If the addition amount of the polyoxyalkylene glycol or the compound of the formula (3) is less than 0.01% by weight, the effect of improving the antistatic property is insignificant. It is-2 weight%.
또한 일반적으로 폴리에스터의 중합에 사용되는 촉매의 사용이 가능하고 인 화합물로써 열안정성을 향상시킬 수도 있다.In addition, it is possible to use a catalyst generally used for the polymerization of polyester and to improve the thermal stability as a phosphorus compound.
본 발명에 의한 폴리에스터 제전사는 폴리에스터섬유 고유의 물성을 저해하지 않으면서도 제전성능이 우수하여 의류용 및 기능복에 널리 사용이 가능하다.The polyester antistatic yarn according to the present invention is excellent in antistatic performance without compromising the inherent physical properties of polyester fibers, and thus can be widely used for clothing and functional clothing.
