Abstract

본 발명은 상용성이 없는 두가지 고분자를 복합방사한 후 후가공 공정에서 각각의 세그먼트로 분할시키는 분할형 복합섬유에 있어서 한 성분은 폴리에스테르, 다른 한 성분은 폴리프로필렌에 폴리부틸렌테레프탈레이트를 첨가시킨 분할형 복합섬유이다.In the present invention, in the split composite fiber in which two polymers having incompatibilities are mixed and spun into each segment in a post-processing process, one component is polyester, and the other component is polybutylene terephthalate added to polypropylene. Split composite fiber.

종래의 폴리에스테르-폴리올레핀계 극세섬유의 경우 부직포 등으로 주로 사용되었는데 본 발명에서는 의류용으로 전개하기 위해 폴리프로필렌에 폴리에스테르의 일종인 폴리부틸렌테레프탈레이트를 일정량 첨가하므로서 각 세그먼트간에 적절한 계면접착력을 갖게하여 알칼리감량 및 염색공정에서만 세그먼트가 분리되어 방사작업성 및 가공성이 향상되도록 하고, 염색성이 우수한 폴리부틸렌테레프탈레이트 성분을 첨가시킴으로서 폴리프로필렌의 염색성도 개선되도록한 것이다.Conventional polyester-polyolefin-based microfibers were mainly used as nonwoven fabrics, but in the present invention, a suitable amount of interfacial adhesion between segments is added by adding a certain amount of polybutylene terephthalate, a kind of polyester, to polypropylene for development in clothing.

Description

염색성과 작업성이 우수한 폴리에스테르-폴리프로필렌 분할형 복합섬유Polyester-polypropylene split composite fiber with excellent dyeability and workability

제1도는 본 발명에 의한 분할형 복합섬유의 단면도로, A부는 폴리에스테르, B부는 폴리부틸렌테레프탈레이트가 첨가된 폴리프로필렌.1 is a cross-sectional view of a split composite fiber according to the present invention, in which A is polyester and B is polybutylene terephthalate.

본 발명은 후가공 공정중에서 각 세그먼트로 분리되어 극세섬유를 형성하는 폴리에스테르-폴리프로필렌으로 구성되는 분할혈 복합섬유로서 염색성과 작업성이 개량된 것이다.The present invention is a divided blood composite fiber composed of polyester-polypropylene that is separated into each segment in the post-processing step to form ultrafine fibers, and the dyeability and workability are improved.

오늘날의 합성섬유는 소비자의 다양한 욕구와 고급화 추세에 부응하여 고부가 가치 제품에 대한 개발 및 생산이 활발하게 진행되고 있다.Today's synthetic fiber is actively developing and producing high value-added products in response to various needs and high-quality trends of consumers.

특히 이중에서도 극세섬유의 사용 용도가 점점 확대되어 가고 있는 가운데 레저스포츠 용품 및 산업용 섬유재로와 패션섬유제품 분양에서 이미 그 특성을 인정받아 호황을 누렸으며, 생활수준의 향상과 함께 하이터치가 더욱 요구되는 경량의 쾌적성 의복 개발에 효과적으로 사용되고 있다.In particular, the use of microfibres has been gradually increasing, and booming has already been recognized for its characteristics in leisure sports goods, industrial textile materials, and fashion textile product distribution. It is effectively used to develop the required lightweight comfort clothing.

이러한 극세사의 개발은 직접방사법외에 복합방사법을 응용한 분할형 또는 용해형법에 의해서 생산되고 있다. 분할형 복합방사법은 하나의 필라멘트 안에 이종의 고분자를 동시에 방사한 후 이들 고분자의 물리화학적 특성에 의해 그 계면을 분할하는 방법으로서 주로 사용되는 고분자는 폴리에스테르-폴리아미드와 폴리에스테르-폴리올레핀계이며, 한 성분을 용해 제거하여 분할시키는 방법에서 주로 사용되는 고분자는 폴리에스테르-개질폴리에스테르이다.The development of such microfibers is produced by the split type or melt type method in which the complex spinning method is applied in addition to the direct spinning method. The split type compound spinning method is a method of dividing a heterogeneous polymer into a single filament at the same time and then dividing the interface by the physical and chemical properties of these polymers. The polymers are mainly polyester-polyamide and polyester-polyolefin type. The polymer mainly used in the process of dissolving and dividing one component is polyester-modified polyester.

폴리에스테르-폴리아미드의 경우 폴리아미드의 가격이 폴리올레핀계 고분자에 비해 고가이며 폴리에스테르와 폴리아미드의 염색 메카니즘이 서로 달라 2욕 염색을 해야하기 때문에 제조원가가 증가하는 단점이 있다. 폴리에스테르-개질폴리에스테르 역시 개질폴리에스테르의 제조원가가 고가이며 각 세그먼트로 분리시 개질 폴리에스테를 용해 제거하기 때문에 생산성저하 및 용해된 성분의 처리에도 어려움이 있다. 한편 폴리에스테르-폴리올레핀계의 경우는 폴리올레핀 고분자의 낮은 융점을 이용하여 부직포의 용도로 주로 개발되고 있다.In the case of polyester-polyamide, the cost of polyamide is higher than that of the polyolefin-based polymer, and the manufacturing cost increases because the dyeing mechanisms of polyester and polyamide are different from each other and two-bath dyeing is required. Polyester-modified polyester also has a high production cost of the modified polyester and is difficult to reduce the productivity and treatment of the dissolved components because the modified polyester is dissolved and removed when separated into each segment. On the other hand, in the case of polyester-polyolefin type, it is mainly developed for the use of a nonwoven fabric using the low melting point of a polyolefin polymer.

본 발명에서는 폴리에스테르-폴리올레핀계 의류용 극세섬유를 개발하기 위해 폴리올레핀계 고분자의 하나인 폴리프로필렌을 사용하였다. 폴리프로필렌은 내화학약품성, 항균방취성, 경량성, 속건성, 물반발력 등이 우수하여 스포츠웨어, 수영복, 의장용 등으로 사용할 수 있으며 가격도 다른 의류용 고분자 보다 저가이다. 폴리프로필렌은 폴리에스테르와 상용성이 전혀 없기 때문에 이 성질을 이용하여 후가공 공정 단계에서 분할시키는데는 유리하지만 제사 및 제직공정에서 물리적 힘에 의해 분할되어 모우발생으로 인한 작업성이 떨어지고 또한 폴리프로필렌은 분자구조가 치밀하고 염착좌석이 없어 염색이 불가능한 단점이 있다.In the present invention, polypropylene, which is one of polyolefin-based polymers, was used to develop microfibers for polyester-polyolefin-based garments. Polypropylene is excellent in chemical resistance, antibacterial deodorization, light weight, quick drying, water repellency, etc., and can be used for sportswear, swimwear, design, etc., and the price is lower than other clothing polymers. Since polypropylene is not compatible with polyester at all, it is advantageous to use this property to divide it in the post-processing step. There is a disadvantage that the dyeing is impossible because of the compact structure and no seating.

본 발명의 목적은 폴리에스테르-폴리프로필렌 복합섬유를 제조할 때 제사 및 제지공정에서의 작업성이 우수하면서 후가공 최종단계인 감량 및 염색단계에서 완전 분할되고 1욕염색에 의해서 효과적인 염색이 가능한 폴리에스테르-폴리프로필렌 분할형 복합섬유를 제공하는데 있다.It is an object of the present invention to produce polyester-polypropylene composite fibers, which are excellent in workability in the weaving and papermaking process, and are fully divided in the reduction and dyeing stages, which are the final stages of post-processing, and which can be effectively dyed by one bath dyeing. To provide a polypropylene split composite fiber.

본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명의 섬유는 폴리에스테르-폴리프로필렌 분할형 복합섬유로서 그 단면의 기본 형상은 제1도와 같이 폴리에스테르성분(A)과 폴리프로필렌성분(B)의 각 세그먼트가 교호로 배열되어 있다. 본 발명의 특징은 폴리에스테르와 폴리프로필렌의 계면에 적당한 정도의 친화성을 부여해서 제사 및 제직공정중에서는 분리가 일어나지 않을 정도의 계면 접착력을 지니고 있도록 하고, 후가공 공정중의 알칼리 감량과 염색시에만 분할이 일어나게 하기 위해 폴리프로필렌에 폴리에스테르계 고분자중 분자구조특성상염색성이 우수한 폴리부틸렌테레프탈레이트 성분을 첨가하므로서 폴리프로필렌의 염색성도 개선되도록 한 점에 있는 것이다.The fiber of the present invention is a polyester-polypropylene split composite fiber in which the basic shape of the cross section is arranged in alternating segments of the polyester component (A) and the polypropylene component (B) as shown in FIG. A feature of the present invention is to provide a moderate degree of affinity to the interface between polyester and polypropylene, so that it has an interface adhesive force such that no separation occurs during the weaving and weaving process, and only during alkali reduction and dyeing during the post-processing process. In order to cause the splitting, polydyne terephthalate component having excellent dyeing properties due to the molecular structure of the polyester polymer is added to the polypropylene to improve the dyeability of the polypropylene.

본 발명에서 폴리부틸렌테레프탈레이트의 첨가량은 폴리프로필렌 세그먼트의 전체 중량에 대해 5~15중량가 되도록 하였다.In the present invention, the amount of polybutylene terephthalate added is 5 to 15 weight based on the total weight of the polypropylene segment. Was made.

본 발명에서 폴리부틸렌테리프탈레이트 성분의 첨가량이 15중량를 초과하면 폴리부틸렌테레프탈레이트는 폴리프로필렌과 상용성이 없기 때문에 방사시 용융파단에 의한 사절이 발생하고, 폴리부틸렌테레프탈레이트는 폴리에스테르계이므로 폴리에스테르 세그먼트를 구성하고 있는 폴리에스테르와 상용성이 있어 각 세그먼트의 계면접착력이 필요이상으로 증가하여 분할단계에서 효과적인 분할을 기대할 수 없게 된다. 또 폴리부틸렌테레프탈레이트 성분을 5중량미만으로 첨가할 경우 각 세그먼트의 계면접착력이 너무 낮게되어 제사 및 제직공정중 분할되어 모우발생으로 작업성이 불량해질 뿐만 아니라 폴리프로필렌성분의 염색성 개량에도 큰 효과가 없게 된다.The amount of the polybutylene terephthalate component added in the present invention is 15 weight If it exceeds, polybutylene terephthalate is not compatible with polypropylene, so trimming occurs due to melt fracture during spinning. Since polybutylene terephthalate is polyester, it is compatible with polyester constituting the polyester segment. As a result, the interfacial adhesion of each segment increases more than necessary, so that effective segmentation cannot be expected in the segmentation step. In addition, 5 weight of polybutylene terephthalate components When added below, the interfacial adhesive force of each segment becomes too low and is divided during the weaving and weaving process, resulting in poor workability due to the occurrence of blemishes, and also does not have a great effect on improving the dyeability of the polypropylene component.

본 발명에서 A성분과 B성분의 복합비는 80~60 중량대 20~40중량가 적당하다.Compound ratio of A component and B component in the present invention is 80 ~ 60 weight 20-40 weight Is suitable.

상술한 바와 같이 폴리에스테르와 폴리부틸렌테레프탈레이트를 첨가한 폴리프로필렌을 사용하여 통상의 복합방사법으로 미연신사를 제조한 다음에 연신하여 연신사로 제조하거나 고속방사설비 및 스핀드로우 방사장치를 통하여 직접연신사로 제조하여 사용할 수 있다.As described above, undrawn yarns are prepared by conventional composite spinning using polypropylene with polyester and polybutylene terephthalate added, followed by drawing to be drawn yarns, or directly drawn through high-speed spinning equipment and spin-draw spinning equipment. It can be manufactured and used.
