본 발명은 내열성 및 내약품성이 우수한 폴리페닐렌 설파이드(이하 PPS라 칭함) 복합섬유에 관한 것으로, 특히, 시스-코아 복합방사법을 사용하여 PPS와 다른 중합체를 복합방사함으로써 PPS 섬유의 우수한 특성을 그대로 유지토록 하려는 것이다. 일반적으로 PPS 섬유는 내열성, 내약품성 등 우수한 특성으로 인하여 산업용 섬유로서 사용이 급속히 신장되고 있으나, 중합체의 가격이 비싸 이로인한 제조경비가 높아 사용상 많은 제약이 따르게 되었다.The present invention relates to a polyphenylene sulfide (hereinafter referred to as PPS) composite fiber having excellent heat resistance and chemical resistance, and in particular, the excellent properties of PPS fibers are maintained as they are by splicing PPS and other polymers by using a cis-core composite spinning method. It is to be maintained. In general, PPS fiber is rapidly being used as an industrial fiber due to its excellent properties such as heat resistance and chemical resistance, but due to the high production cost due to the high cost of the polymer, many constraints have been placed on use.

이러한 단점을 해결하기 위해 종래에는 다른 고분자와 블렌딩하여 혼합방사하거나 또는 PPS를 커버링사(絲)로서 사용하였으나 이는 모두 PPS 섬유의 특성인 내열성 또는 내약품성을 유지하는데 한계가 따르거나 상기의 제조경비를 크게 절감시키지 못하는 문제점이 있었다.In order to solve this disadvantage, conventionally, blended spinning with other polymers or mixed spinning or PPS was used as a covering yarn, but all of them have limitations in maintaining heat resistance or chemical resistance, which are characteristics of PPS fibers, There was a problem that can not greatly reduce.

따라서 본 발명에서는 PPS 중합체와 다른 중합체를 시스-코아 복합방사법에 의해 복합섬유로 제조함으로써, PPS 섬유의 우수한 특성은 그대로 유지함과 아울러 제조경비 또한 절감시키려 함에 그 목적이 있는 것이다.Therefore, in the present invention, the PPS polymer and other polymers are prepared by the composite fiber by the cis-core composite spinning method, to maintain the excellent properties of the PPS fibers as well as to reduce the manufacturing cost.

이하 첨부된 도면과 관련하여 상세히 설명하면 다음과 같다.Hereinafter will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 의해 제조된 복함섬유의 횡단면 구성도로서, 본 발명에서 언급하고 있는 시스성분과 코아성분은 제1도에서와 같이 복합섬유(J) 횡단면도의 중심부를 코아성분(C)이라 하고, 외곽부는 시스성분(S)이라 한다.1 is a cross-sectional configuration of the composite fiber produced by the present invention, the cis component and the core component referred to in the present invention is the core of the cross-sectional view of the composite fiber (J) as in FIG. The outer portion is referred to as the sheath component (S).

상기 코아성분(C)에는 플레에스터, 폴리아마이드, 폴리올레핀 등 용융방사 가능한 중합체를 사용하고 시스성분(S)에는 멜트플로인댁스(Melt Flow Index : 이하 MI라 칭함)가 5∼300g/10min(ASTM-D-1238-70)인 PPS 중합체를 사용하되, 시스성분인 PPS는 하기의 일반식과 같은 구조를 가지며,The core component (C) is a melt-spun polymer such as polyester, polyamide, polyolefin, etc., and the sheath component (S) has a melt flow index (hereinafter referred to as MI) of 5 to 300 g / 10 min ( PPS polymer of ASTM-D-1238-70) is used, but the cis component PPS has a structure as shown in the following general formula,

단, m : n=100 : 0-50 : 50(몰비)However, m: n = 100: 0-50: 50 (molar ratio)

상기한 바에서 MI가 5이하 또는 300을 초과시에는 제사가 곤란하며, 바람직하게는 MI 50∼200인 중합체를 사용하여 통상의 시스-코아 복합방사법으로 섬유를 제조한다. 이때 시스성분은 전체 면적비율로 30∼70%이고, 나머지는 면적비율은 코아성분일때 공정성은 양호하면서 PPS의 특성인 내약품성을 그대로 유지하는 섬유를 제조할수 있다.As described above, when the MI is less than 5 or more than 300, it is difficult to make a yarn, and fibers are prepared by conventional cis-core composite spinning using a polymer having a MI of 50 to 200. At this time, the sheath component is 30 to 70% in the total area ratio, and the remainder in the core ratio is the core component can be produced a fiber that has good processability while maintaining the chemical resistance characteristics of the PPS.

그러나 시스성분이 전체 면적비율의 30% 이하일 경우 즉, 코아성분이 70% 이상이 되면 코아성분이 섬유상에서 한쪽으로 치우치거나 섬유표면으로 돌출되는 현상이 발생하여 결과적으로 전체 섬유의 내약품성이 저하된다.However, if the sheath component is 30% or less of the total area ratio, that is, the core component is 70% or more, the core component may be biased to one side or protrude to the fiber surface, resulting in a decrease in chemical resistance of the entire fiber. do.

또 시스성분이 전체 면적비율의 70% 이상일 경우 즉, 코아성분이 30% 이하로 되면 방사시 코아성분이 섬유 중심축에 자리잡기가 어려우며 제조경비의 절감효과도 크지 못하게 된다.In addition, when the sheath component is 70% or more of the total area ratio, that is, the core component is less than 30%, the core component is difficult to settle on the fiber central axis during spinning, and the effect of reducing the manufacturing cost is not great.

따라서 상기와 같은 본 발명의 적용조건으로 복합방사에 의해 PPS 섬유를 제조할 경우 단독방사로 제조한 PPS 섬유에 비해 제조경비가 크게 절감되면서 PPS의 특성인 우수한 내열성, 내약품성 등을 그대로 유지할 수 있으므로 요구되는 산업용 섬유분야에서 경제적으로 사용할 수 있는 효과를 갖게 되는 것이다.Therefore, when manufacturing PPS fiber by the composite spinning according to the application conditions of the present invention as described above, it is possible to maintain the excellent heat resistance, chemical resistance, etc. of the characteristics of the PPS while significantly reducing the manufacturing cost compared to the PPS fiber produced by single spinning It will have an effect that can be used economically in the field of industrial textiles required.

이하 본 발명을 실시예 및 비교예를 통하여 보다 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.
