Description
본 발명은 개질폴리에스터와 폴리아마이드를 방사형 복합방사한 4-20분할형 복합섬유의 피브릴화 방법에 관한 것이다.The present invention relates to a fibrillation method of 4-20 split composite fibers in which radially spun composite modified polyester and polyamide.
특히 분할형 복합섬유로 제조된 직편물을 액류염색기내에서 적절한 분할제를 사용하여 직편물의 고유한 물성을 유지할 뿐만 아니라 피브릴화율을 향상시키는 방법에 관한 것이다.In particular, the present invention relates to a method for improving the fibrillation rate as well as maintaining the inherent physical properties of the knitted fabric by using an appropriate dividing agent in a liquid dyeing machine.
종래에는 폴리에스터와 폴리아마이드로 제조된 분할형 복합섬유를 피브릴화시키기 위하여 3가지 방법이 주로 사용되어 왔다.Conventionally, three methods have been mainly used to fibrillate split composite fibers made of polyester and polyamide.
첫째, 복합섬유의 한 성분을 적정한 용매로 사용하여 용해시키거나, 둘째 양성분을 기계적인 방법으로 충격등을 주어 강제로 분리시키거나, 셋째 양성분을 화학처리로 팽윤이나 수축을 일으켜 피브릴화 하였다.Firstly, one component of the composite fiber is used as a suitable solvent to dissolve it, secondly, the cationic component is forcedly separated by impact, etc., or thirdly, the cationic component is swelled or shrunk by chemical treatment, resulting in fibrillation. It was.
이러한 방법들에 대한 기존의 기술들에 대한 문제점으로 용해에 의한 방법은 20%이상의 성분을 용해함에 따른 소재의 손실 및 용제의 독성과 취급방법이 매우 주의를 요하여 분할형 복합섬유의 피브릴화 공정으로 거의 사용되지 않고 있다. 기계적인 방법에 의한 피브릴화 방법은 공정시간이 길고, 피브릴화율이 낮다는 단점을 가지고 있다.As a problem with the existing techniques for these methods, the dissolution method requires fibrillation of split composite fibers due to the loss of material caused by dissolving more than 20% of the components, the toxicity of the solvent, and the handling method. It is rarely used as a process. The fibrillation method by the mechanical method has a long process time and a low fibrillation rate.
화학처리에 의한 복합섬유를 팽윤, 수축시키는 방법은 오늘날 전기 두 방법에 의하여 광범위하게 쓰여지는데, 주로 개미산, 초산, 페놀, 벤질알콜, 베타-페놀에틸알콜, 메타-크레졸, 계면활성제, 가성소다 등을 분할제로 선택 조합하여 사용하고 있다.Swelling and shrinking of composite fibers by chemical treatment are widely used today by two methods, mainly formic acid, acetic acid, phenol, benzyl alcohol, beta-phenol ethyl alcohol, meta-cresol, surfactants, caustic soda, etc. Is selected and used as a splitting agent.
이러한 조성물로 피브릴화된 복합섬유의 직편물은 피브릴화율이 완전하지 못할뿐더러, 페놀 또는 벤질알콜의 유화용액이나 개미산을 사용할 때 폴리아마이드 부분을 용해 또는 가소화를 심하게 일으켜 직편물의 강도, 탄성회복율등을 저하시킬 뿐만 아니라 촉감을 심하게 손상시킨다. 더구나 페놀계 용제는 인체독성이 강하고, 폐수처리 공정을 필수적으로 해야하는 결점이 있었다.The fibrillated composite fibers of such a composition may not have a complete fibrillation rate, and when the emulsion or formic acid of phenol or benzyl alcohol is used, the polyamide portion may be dissolved or plasticized severely, resulting in the strength of the knitted fabric, It not only lowers the elastic recovery rate but also damages the touch badly. In addition, phenolic solvents have a strong human toxicity, and the waste water treatment process must be essential.
상기와 같은 종래의 문제점을 해결하기 위하여 본 발명은 복합섬유의 고유한 광택과 물성을 저하시키지 않는 분할제의 선정 및 조합과 함께 피브릴화 공정을 종래의 윈스, 지거, 로타리워셔, 연속수세기에서 하던 것을 액류염색기에서 진행하여 피브릴화율을 높였다.In order to solve the above conventional problems, the present invention provides a fibrillation process in the conventional wins, jiggers, rotary washers, continuous centuries with the selection and combination of splitting agents that do not degrade the inherent gloss and physical properties of the composite fiber. It was carried out in the liquid dyeing machine to increase the fibrillation rate.
특히 종래의 복합섬유 피브릴화 방법에서는 주로 폴리에스터나 폴리아마이드를 분해시키는 알칼리나 페놀유화용액을 사용함으로서 복합섬유가 가지는 고유한 물성이 저하되었다.In particular, in the conventional composite fiber fibrillation method, the inherent physical properties of the composite fiber are reduced by using an alkali or a phenol emulsion solution mainly decomposing polyester or polyamide.
따라서 본 발명에서는 분할제로 알킬소디움설포네이트 또는 알킬아릴소디움설포네이트와 미량의 알칼리 및 피브릴화 촉진제로 주기율표상의 1A 또는 2A족 원소의 염 또는 캐리어중 하나 또는 두가지를 동시에 병용하므로서 복합섬유를 구성하고 있는 폴리에스터나 폴리아마이드에 상해를 주지않고 피브릴화를 할 수 있었다.Therefore, in the present invention, a composite fiber is formed by simultaneously using one or two of alkyl sodium sulfonate or alkyl aryl sodium sulfonate as a dividing agent and a salt or a carrier of a 1A or 2A group element of the periodic table with trace alkali and fibrillation accelerators. Fibrillation was possible without harming the polyester or polyamide.
이것은 본 발명의 대상이 되는 복합섬유의 소재중 개질 폴리에스터 부분이 금속술폰산염을 함유한 이소프탈레이트 성분이 분자쇄내에 불규칙하게 존재하고 있음으로써 음이온 계면활성제중 알킬소디움술포네이트 또는 알킬아릴소디움술포네이트가 비교적 침투가 빠르고 따라서 폴리아마이드와 개질폴리에스터의 계면에서 표면장력을 저하시켜 물의 침투 및 확산을 용이하게 하여 피브릴화의 조건을 만들게 된다. 뿐만 아니라 주기율표상의 1A 또는 2A족 원소의 염도 폴리아마이드에 대하여 상기와 같은 역할에 기여할 것으로 추측되며, 캐리어는 개질폴리에스터 분자쇄를 완화하여 열수축 온도를 저하시키고 피브릴화 온도인 95℃∼98℃에서의 분자쇄 운동성을 첨가하지 않을 때보다 더 크게 일으켜 복합섬유의 구성소재인 개질폴리에스터의 팽윤 및 수축을 높여서 피브릴화 촉진시킨다. 따라서 용제에 의한 복합섬유의 팽윤 및 수축에 의한 피브릴화 방법에서 발생하는 복합섬유의 용해 및 상해를 본 발명에서는 비용제형을 분할제로 사용함으로써 복합섬유의 물성을 보존할 수 있다.This is because the isophthalate component containing the metal sulfonate in the modified polyester portion of the composite fiber material of the present invention is irregularly present in the molecular chain, and thus alkyl sodium sulfonate or alkyl aryl sodium sulfonate in the anionic surfactant. It is relatively fast to penetrate and thus lowers the surface tension at the interface between the polyamide and the modified polyester, thereby facilitating the penetration and diffusion of water to create the conditions of fibrillation. In addition, the salts of elements 1A or 2A on the periodic table are also believed to contribute to the above role for polyamides, and the carriers relax the modified polyester molecular chain to lower the heat shrinkage temperature and the fibrillation temperature of 95 ° C to 98 ° C. Molecular chain motility in Essence is greater than when not added to increase the swelling and shrinkage of the modified polyester, a component of the composite fibers to promote fibrillation. Therefore, in the present invention, dissolution and injury of the composite fiber generated in the fibrillation method by swelling and shrinking of the composite fiber by the solvent can preserve the physical properties of the composite fiber by using the non-formulation as the dividing agent.
상기의 본 발명의 구성을 보다 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention in more detail as follows.
본 발명의 개질폴리에스터로는 구조식(Ⅰ)의 금속술폰산염을 함유한 이소프탈레이트 성분이 전체 디액시드의 0.3∼10.0몰퍼센트 함유된 폴리에스터 공중합체를 사용하였는데 이때 이소프탈레이트 성분이 0.3퍼센트이하일 경우에는 피브릴화가 곤란하고, 10.0퍼센트를 초과할 경우에는 제사가 곤란하다.As the modified polyester of the present invention, a polyester copolymer containing 0.3-10.0 mole percent of the total diacid in which the isophthalate component containing the metal sulfonate of formula (I) is used, wherein the isophthalate component is less than 0.3 percent Fibrillation is difficult, and when it exceeds 10.0 percent, ritual is difficult.
(단 R은 H 또는 탄소수 1∼6의 알킬기 또는 아릴기를 나타내고, M은 알칼리금속 화합물임)(Where R represents H or an alkyl or aryl group having 1 to 6 carbon atoms and M is an alkali metal compound)
그리고 분할제로는 구조식(Ⅱ)의 음이온계면활성제로써 예를들면 알칼디움설포네이트와 알킬아릴소디움설포네이트 등을 0.01∼0.5중량퍼센트 사용하고, 구조식(Ⅲ)인 미량의 알칼리를 0.01∼0.3중량퍼센트를 사용하였는데 이때 음이온계면활성제의 양이 0.01중량퍼센트 이하일 경우에는 피브릴화가 곤란하고 0.5중량퍼센트 이상에서는 작업성이 불량하였으며 알칼리는 0.01중량퍼센트이하일 경우 피브릴화가 곤란하고 0.3중량퍼센트를 초과할 경우에서는 강도 및 탄성회복율이 저하되는 것을 알았다.As the dividing agent, for example, an alkali surfactant of the structural formula (II) is used, for example, 0.01 to 0.5% by weight of an alkaldium sulfonate and an alkylaryl sodium sulfonate, and 0.01 to 0.3% by weight of a trace alkali of the structural formula (III). In this case, when the amount of the anionic surfactant is 0.01% by weight or less, fibrillation is difficult, workability is poor at 0.5% by weight or more, and when alkali is less than 0.01% by weight, it is difficult to be fibrillated and exceeds 0.3% by weight. It was found that the strength and the elastic recovery rate were lowered at.

또한 피브릴화 촉진제로는 주기율표상의 1A 또는 2A족 원소의 염 또는 캐리어중 하나 또는 두가지를 동시에 사용하였는데 주기율표상의 1A 또는 2A족 원소의 염은 구조식(Ⅳ)의 화합물중 하나를 0.01중량퍼센트 이상 사용하였고 캐리어로는 2,4-디클로로페놀의 에테르형, 디메틸테레프탈레이트, 메틸디클로페녹시아세테이트 또는 N-알킬나프탈이미드유도체중에서 하나를 0.1∼3중량퍼센트 사용하였는데 이때 주기율표상의 1A 또는 2A족 원소의 염은 0.01중량퍼센트 미만일 경우 피브릴화가 곤란하였으나 그 이상에서는 양호하였으며 특히 5.0중량퍼센트이하일 경우에 양호하였다. 그리고 캐리어의 경우 0.1중량퍼센트 미만에서는 피브릴화가 곤란하였고 3중량퍼센트를 초과할 경우에는 직편물상에 얼룩을 발생시키는 결점이 있었다.In addition, one or both salts or carriers of group 1A or 2A elements on the periodic table were used simultaneously as the fibrillation promoter. The salts of elements 1A or 2A on the periodic table used 0.01% by weight or more of the compound of formula (IV). As a carrier, 0.1 to 3% by weight of an ether type of 2,4-dichlorophenol, dimethyl terephthalate, methyldichlorophenoxyacetate, or N-alkylnaphthalimide derivative was used. The salt of the element was difficult to fibrillate when less than 0.01% by weight, but it was good above, especially when less than 5.0% by weight. In the case of carriers, fibrillation was difficult at less than 0.1% by weight, and when the carrier was more than 3% by weight, staining occurred on the knitted fabric.
