본 발명은 3성분 해도형 복합섬유에 관한 것으로서, 더욱 상세하게는 섬도와 배열이 다른 2종의 도성분이 해성분에 분산되어 있는 3성분 해도형 복합섬유에 관한 것이다.The present invention relates to a three-component islands-in-the-sea composite fiber, and more particularly, to a three-component island-in-the-sea composite fiber in which two island components having different degrees of fineness and arrangement are dispersed in sea components.
일반적으로 해도형 복합섬유는 인공피혁, 와이핑 원단 등의 재료로 널리 사용되고 있는데, 종래에는 해, 도성분, 즉 2성분으로 구성된 해도형 복합섬유가 주로 사용되어 왔기 때문에 해성분 용출 후 남아있는 1종의 도성분 폴리머에 의해 섬유의 특성이 좌우된다.In general, island-in-the-sea composite fiber is widely used as a material such as artificial leather, wiping fabric, etc. Conventionally, sea island-type composite fiber, which consists of two components, has been mainly used. The properties of the fiber depend on the island-based polymer of the species.
특히, 해성분이 알카리 이용출성 폴리머이고 도성분이 폴리에스테르인 경우 해성분 용출 후 도성분의 취화로 물성이 크게 저하되는 단점이 있다.In particular, when the sea component is an alkaline soluble polymer and the island component is polyester, there is a disadvantage in that physical properties are greatly reduced by embrittlement of the island component after the sea component is eluted.
또한, 용출 후의 물성을 보완하기 위해 3성분의 폴리머를 사용하여 제조하는 해도형 복합섬유의 경우 용융압출기, 계량펌프, 스태틱 믹서, 팩장치 등의 설비가 추가로 필요하며 복잡하여 설비의 가격이 고가인 단점이 있다.In addition, the island-in-the-sea composite fiber manufactured by using a polymer of three components to supplement the physical properties after dissolution requires additional equipment such as a melt extruder, a metering pump, a static mixer, and a packer. There is a disadvantage.
본 발명은 이러한 종래 기술의 문제점을 해결하기 위한 것으로, 해성분 중에 섬도가 같고 균일하게 배열된 제1도성분과 섬도가 다르고 불규칙하게 배열된 제2도성분이 형성되어 있어서, 기존의 방사 설비를 그대로 이용할 수 있으면서 해성분 용출 후의 섬유의 물성이 우수하고 세섬도 및 이수축 효과 발현이 가능한 3성분 해도형 복합섬유를 제공하는데 그 목적이 있다.The present invention is to solve the problems of the prior art, the first degree component is the same degree of fineness and uniformly arranged second degree component in the sea component is formed differently and irregularly arranged, to use the existing radiation equipment as it is It is an object of the present invention to provide a three-component islands-in-the-sea composite fiber capable of being able to express the fineness and bishrinkage effect of the fiber after the sea component elution.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 해성분과 도성분으로 이루어진 해도형 복합섬유에 있어서, 해성분(1)은 폴리에스테르 공중합량이 5∼25중량%인 공중합 폴리에스테르, 제1도성분(2)은 길이 방향으로 연속적이며 균일한 섬도와 규칙적인 배열을 갖는 폴리에스테르, 제2도성분(3)은 섬도가 다르고 불규칙적으로 분산, 배열되어 있는 폴리아미드인 것을 특징으로 하는 3성분 해도형 복합섬유에 관한 것이다.In the present invention, in the island-in-the-sea composite fiber composed of sea component and island component, sea component (1) is a copolymerized polyester having a polyester copolymerization amount of 5 to 25% by weight, and the first island component (2) is continuous and uniform in the longitudinal direction. Polyester having a regular degree of fineness and the second degree of constitution (3) relates to a three-component islands-in-the-sea composite fiber characterized in that the fineness is polyamide having different fineness and is irregularly dispersed and arranged.
이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명에서 해성분으로는 알카리 용해성이 우수한 공중합 폴리에스테르로서, 폴리에틸렌테레프탈레이트를 주성분으로 하고 부가성분으로서 폴리에틸렌글리콜, 폴리프로필렌글리콜, 1, 4-사이클로헥산디카르복실산, 1, 4-사이클로헥산디메탄올, 1, 4-사이클로헥산디카르복실레이트, 2-메틸-1,3-프로판디올, 2, 2-디메틸-1,3-프로판디올, 2, 2-디메틸-1, 4-부탄디올, 아디프산 중에서 선택된 하나 또는 둘이상을 5~25중량% 공중합시킨 것이다.In the present invention, as a sea component, a copolymer polyester having excellent alkali solubility, which is polyethylene terephthalate as a main component and polyethylene glycol, polypropylene glycol, 1,4-cyclohexanedicarboxylic acid, 1,4-cyclohexane Dimethanol, 1, 4-cyclohexanedicarboxylate, 2-methyl-1,3-propanediol, 2, 2-dimethyl-1,3-propanediol, 2, 2-dimethyl-1, 4-butanediol, 5 to 25% by weight of one or two or more selected from adipic acid is copolymerized.
만일 부가성분이 5중량% 미만이면 해성분의 용출성이 저하되고 25중량%를 초과하면 점도 하락으로 방사성이 나빠진다.If the additive component is less than 5% by weight, the solubility of the sea component is lowered, and if it exceeds 25% by weight, the radioactivity is deteriorated due to the viscosity decrease.
이러한 폴리에스테르 공중합 성분은 제2도성분 형성과 용출에 아주 유용한 성분이다. 예를 들어 금속 설포네이트기를 갖는 화합물을 공중합 성분으로 할 경우 제2도성분의 형성이 잘 안되며 방사성이 저하된다.These polyester copolymer components are very useful components for forming and eluting the second degree component. For example, when a compound having a metal sulfonate group is used as a copolymerization component, formation of the second degree component is poor and radioactivity is lowered.
또한, 제1도성분으로는 길이 방향으로 연속적이며 균일한 섬도와 규칙적인 배열을 가지는 폴리에스테르 또는 개질 폴리에스테르를 사용하고 제2도성분으로는 폴리아미드 및/또는 개질 폴리아미드를 사용하는 바, 나일론6, 나일론66, 나일론610 등이 효과적이며 해성분 중에 섬도 및 배열이 불규칙적으로 분산되도록 한다.In addition, as the first degree component, polyester or modified polyester having a continuous and uniform fineness and regular arrangement in the longitudinal direction is used, and as the second degree component, polyamide and / or modified polyamide are used. Nylon 6, nylon 66, nylon 610 and the like are effective and allow the fineness and arrangement of the sea to be distributed irregularly.
본 발명의 복합 섬유를 제조하는 방법을 설명하면, 우선 해성분과 제2도성분을 칩 상태로 혼합하여 용융압출기에 투입하는데 그 비율은 해성분이 40∼90중량%, 제1도성분이 60∼10중량%가 되도록 한다.Referring to the method of manufacturing the composite fiber of the present invention, first, the sea component and the second degree component are mixed in a chip state and introduced into a melt extruder, and the ratio is 40 to 90% by weight of the sea component and 60 to 10 weight of the first degree component. To%.
제1도성분은 다른 용융압출기에 공급하는데 그 비율은 해성분과 제2도성분의 합이 20∼50중량%, 제1도성분이 50∼80중량%가 되도록 한다.The first degree component is fed to another melt-extruder so that the ratio of the sea component and the second degree component is 20 to 50% by weight, and the first degree component is 50 to 80% by weight.
팩 장치로는 국내 특허 제45281호의 해도형 복합 섬유용 구금장치를 사용하여 방사속도 700∼1,500m/분으로 미연신사를 제조 후 연신하여 필라멘트 또는 스테이플을 제조한다.As a pack device, a filament or staple is manufactured by drawing and stretching an undrawn yarn at a spinning speed of 700-1,500 m / min using a detention device for island-in-the-sea composite fiber of Korean Patent No. 45241.
제1도성분의 해성분 용출 후 단사 섬도는 0.05∼0.15데니어이고, 제2도성분의 단사 섬도는 0.05데니어 이하이고 갯수는 10∼100개이다.The single yarn fineness after the sea component elution of the first degree component is 0.05 to 0.15 denier, the single yarn fineness of the second degree component is 0.05 denier or less and the number is 10 to 100.
이하, 본 발명을 실시예 및 비교예를 통하여 더욱 구체적으로 설명하겠는 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited by the Examples.
