Description
본 발명은 염색성이 우수한 초극세사 부직포 인공피혁의 제조방법에 관한 것이다. 보다 상세하게는 폴리아미드, 혹은 폴리에스테르를 제1성분(섬유성분)으로 하고 융점 120℃ 이하의 폴리에틸렌, 혹은 폴리스타이렌을 제2성분(피용출성분)으로 한 혼합방사를 통해 농색효과 및 염색 견뢰도가 우수한 초극세사 부직포 인공피혁을 제조하는 방법을 제공하는 것이다.The present invention relates to a method for producing a microfiber nonwoven artificial leather excellent dyeing properties. More specifically, the deepening effect and color fastness are obtained through mixed spinning using polyamide or polyester as the first component (fiber component) and polyethylene having a melting point of 120 ° C. or lower, or polystyrene as the second component (elution component). It is to provide a method for producing an excellent microfiber nonwoven artificial leather.
종래 극세사 부직포 인공피혁의 제조방법은 국내특허 공개번호 93-006245, 90-010138등에 개시되어 있으며, 나일론 혹은 폴리에스테르와 이용성 폴리머를 사용하여 복합방사를 통해 해도형 극세사 스테이플 섬유를 제조하여 니들펀칭으로 부직포 펠트를 만든 뒤 알카리 수용액으로 이용성 폴리머를 제거하여 구성섬유를 극세화한 다음, 아민 등의 산성염료와 친화력을 갖는 첨가제과 에스테를 타입, 혹은 에테르 타입의 폴리우레탄 혼합용액에 펠트를 함침시켜 탄성을 부여하고 염색, 버핑 등 일련의 후가공 공정을 거쳐 제조한다.Conventional methods of manufacturing microfibre nonwoven artificial leather are disclosed in Korean Patent Publication Nos. 93-006245, 90-010138, and the like, and needle-punching by producing island-in-the-sea microfiber staple fibers through composite spinning using nylon or polyester and a usable polymer. After making nonwoven fabric felt, remove the usable polymer with alkaline solution to make constituent fibers fine, and then impregnate the felt with additives or ester-type or ether-type polyurethane mixed solution having affinity with acid dyes such as amines to give elasticity. It is produced through a series of post-processing processes such as dyeing and buffing.
그러나 이러한 종래의 부직포 인공피혁의 제조방법은 단사섬도 0.01데니어 이하의 심색성을 지닌 초극세사 부직포 인공피혁 제조에는 여러 가지 문제점을 야기할 수 있다. 즉, 기존의 염색방법으로는 블랙이나 진한 브라운색 같은 농색을 지닌 0.01 데니어 이하의 초극세사 부직포 인공피혁을 제조할 수 없을 뿐만 아니라, 많은 량의 염료를 사용해야 하는 관계로 염색견뢰도가 1~2급 수준에 머물러 고품질의 부직포 인공피혁을 제조할 수 없다.However, the conventional manufacturing method of the nonwoven artificial leather may cause various problems in the production of ultra-fine nonwoven artificial leather having a deep color of less than 0.01 denier single yarn fineness. In other words, the existing dyeing method cannot produce artificial microfibres of 0.01 micron or less with a deep color such as black or dark brown color, and dyeing fastness is in the 1st ~ 2nd level because a large amount of dye must be used. It cannot stay and manufacture high quality nonwoven artificial leather.
또한, 폴리우레탄에 아민 등의 산성염료와 친화력을 갖는 첨가제를 혼합하여 함침시켜 부직포 인공피혁을 제조하는 방법은 단순한 폴리우레탄의 염색성의 향상만으로는 농색발현 및 염색 견뢰도가 우수한 부직포 인공피혁의 제조가 현실적으로 어렵다.In addition, the method of manufacturing nonwoven artificial leather by mixing impregnated with an additive having affinity with acid dyes, such as amines in the polyurethane, the production of non-woven artificial leather excellent in deep color expression and dyeing fastness by simply improving the dyeability of polyurethane. it's difficult.
일본 특개소 59-12789에서는 N-비닐피롤리돈이나 디알킬아민에틸 메타아크릴레이트 등을 폴리우레탄 탄성체에 공중합하여 염착좌석을 부여하는 방법이 개시되어 있으나 이 발명에 기술된 폴리우레탄 탄성체는 이중 결합이 없어 순수한 그라프트가 되었다고 보기 어렵고 공정이 상당히 복잡한 단점을 지니고 있다.Japanese Patent Laid-Open No. 59-12789 discloses a method of copolymerizing N-vinylpyrrolidone, dialkylamineethyl methacrylate, etc. to a polyurethane elastomer to impart a salted seat, but the polyurethane elastomer described in the present invention is a double bond. It is difficult to see that it is pure graft because of the lack of process, and the process is quite complicated.
본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로 농색의 발현이 용이하고 염색 견뢰도가 우수한 초극세사 부직포 인공피혁을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a microfiber nonwoven artificial leather that is easy to express the deep color and excellent in color fastness to solve the problems as described above.

이상의 실시예 및 비교예를 통하여 나타난 인공피혁의 염색견뢰도 및 농염성 등을 다음의 표 1에 나타내었다.Dyeing fastness and thick salt of artificial leather shown through the above Examples and Comparative Examples are shown in Table 1 below.
본 발명에 의해 나타나는 효과는, 종전 방사로 된 해도형 원사인 최종 단사섬도 0.01데니어 이상인 부직포 인공피혁과는 달리, 단사섬도 0.01데니어 이하의 초극세사 부직포 인공피혁은 염색되야 하는 원사표면적이 기존 원사에 비해 훨씬 넓어지는 관계로 착색이 된 원착사를 사용 부직포 펠트를 제조 이후에 염색함으로써 농색발현 및 양호한 염색견뢰도 확보에 용이한 장점을 지니고 있다. 이렇게 제조된 부직포 인공피혁은 천연피혁 대용으로 의료용 및 잡화용으로 사용할 수 있다.The effect of the present invention is that, unlike the non-woven artificial leather of the final single yarn fineness of 0.01 denier or more, which is the island-in-the-sea yarn made of conventional spinning, the ultra-fine nonwoven artificial leather of 0.01 denier or less of the single yarn fineness has a yarn surface area which must be dyed, compared to the conventional yarn. Since it is much wider, the nonwoven fabric felt is dyed after being manufactured using colored yarns which have been colored, which has the advantage of facilitating dark color expression and good color fastness. Non-woven artificial leather manufactured in this way can be used for medical and sundries instead of natural leather.
