According to the present invention, the blended filament comprises: one type of high-melting polymer yarn disposed at the central portion of the cross-section of the blended filament and selected from polyester and nylon; and an orange-type composite fiber disposed at the other edge portion of the cross-section of the blended filament except for the central portion. The orange-type composite fiber includes high-melting polymer segments (B) and low-melting polymer segments (A), in which a natural insect repellent-containing material is mixed, alternately arranged on the cross-section of the composite fiber. The low-melting polymer segments (A) include: (i) a straight portion extending from the center point of the cross-section of the composite fiber to the outer circumferential surface of the cross-section of the composite fiber up to 2/3 to 3/4 of the radius of the cross-section of the composite fiber; and (ii) a curved portion having a horn shape extending from one end of the straight part adjacent to the outer circumferential surface of the cross-section of the composite fiber to the outer circumferential surface of the same, wherein the total surface area ratio of the low melting point polymer segments (A) to the same of the composite fiber is less than 50%. Accordingly, the cross-section of the orange-type composite fiber forming the blended filament is not divided and the low-melting polymer segments (A) mixed with the natural insect repellent-containing material are exposed to a surface of the composite fiber, and thus a good insect repellent effect is provided for a long time. More than 50% of the total surface area of the fiber is made of the high-melting polymer segments that are nylon or polyester, and thus the blended filament can be dyed. Moreover, the blended filament includes the high-melting polymer yarn, thereby providing excellent strength.

Description

방충성이 우수한 혼섬사{Blended filament with excellent anti-insect property}Blended filament with excellent anti-insect property}

본 발명은 방충성이 우수한 혼섬사에 관한 것으로서, 보다 구체적으로는 적절한 강도를 구비하고, 방충성능이 서서히 오랫동안 발현되고, 염색이 가능하고, 혼섬사를 구성하는 복합섬유 내 폴리머 세그멘트 들이 쉽게 분할되지 않아 복합섬유의 단면 형태를 안정적으로 유지할 수 있는 방충성이 우수한 혼섬사에 관한 것이다.The present invention relates to a blended yarn having excellent insect repellency, and more specifically, has an appropriate strength, exhibits an insect repellent performance for a long time, can be dyed, and polymer segments in the composite fibers constituting the blended yarn are not easily divided. Therefore, it relates to a blended yarn having excellent insect repellency that can stably maintain the cross-sectional shape of the composite fiber.

방충성 합성섬유를 제조하는 종래방법으로는 방충제를 담지시킨 무기 담지체 또는 방충제를 담고 있는 마이크로 캡슐 (이하 "방충제 함유 물질" 이라고 한다)을 폴리에스터 또는 나일론을 용융방사할 때 방사공정에서 용융된 폴리에스터 또는 나일론 폴리머에 첨가하는 방법이 널리 사용되어 왔으나, 상기 종래방법으로는 방충제로 인체에 무해하지만 열안정성이 떨어지는 천연 성분의 방충제를 사용하는 경우 상기 천연 방충제가 용융방사 공정에서 가해지는 열에 의해 방충기능을 상실하게 되는 문제가 발생되었다.In the conventional method of manufacturing insect-repellent synthetic fibers, an inorganic carrier supporting an insect repellent or a microcapsule containing an insect repellent (hereinafter referred to as "repellent-containing material") is melted in the spinning process when polyester or nylon is melt-spun. Although the method of adding to polyester or nylon polymer has been widely used, in the conventional method, when using a natural insect repellent that is harmless to the human body as an insect repellent, but has poor thermal stability, the natural insect repellent is caused by heat applied in the melt spinning process. There was a problem that the insect repellent function was lost.

또 다른 종래기술로는 용융방사시 가해지는 열에 의해 천연 방충제의 방충기능이 상실되는 것을 방지하기 위해서 폴리올레핀계 폴리머 등과 같이 융점이 200℃ 이하인 저융점 폴리머 내에 천연 방충제 함유 물질을 첨가하여 천연 방충제 함유 물질이 첨가된 저융점 마스터 배치 칩을 제조한 다음, 상기 저융점 마스터 배치 칩과 폴리에스터 또는 나일론 등과 같은 고융점 폴리머 칩을 시스-코어(Sheath-Core)형 원사단면으로 복합방사할 때 저융점 폴리머를 시스 부위에 배치하고 고융점 폴리머를 코어부분에 배치되도록 복합방사하여 방충성 복합섬유를 제조하는 방법도 사용되어 왔다.In another prior art, in order to prevent the loss of the insect repellent function of the natural insect repellent due to heat applied during melt spinning, a natural insect repellent-containing substance is added to a low melting point polymer having a melting point of 200° C. or lower, such as a polyolefin-based polymer. After preparing the added low-melting-point master batch chip, the low-melting-point polymer when composite spinning the low-melting-point master batch chip and high-melting-point polymer chip such as polyester or nylon into a sheath-core yarn cross-section A method of preparing an insect-repellent composite fiber has also been used by disposing a high-melting-point polymer in the sheath portion and composite spinning so that the high-melting point polymer is disposed in the core portion.

그러나, 상기 종래방법으로 제조된 방충성 복합섬유는 강도가 떨어지고, 방충성분을 함유한 저융점 폴리머가 원사표면에 모두 노출되기 때문에 방충성능의 지속시간이 짧아지고, 저융점 폴리머로 폴리올레핀계를 사용할 경우 염색이 불가능하게 되는 문제점이 있다는 것을 확인하고 본 발명을 완성하게 되었다.However, the insect-repellent composite fiber produced by the above conventional method has low strength, and since the low-melting-point polymer containing the insect-repellent component is all exposed to the yarn surface, the duration of the insect-repellent performance is shortened. In this case, it was confirmed that there is a problem that dyeing is impossible, and the present invention was completed.

본 발명의 과제는 적정 강도를 구비하고, 염색이 가능하고, 혼섬사를 구성하는 복합섬유의 세그멘트들이 쉽게 분할되지 않아 형태 안정성이 우수하고, 방충성능이 오랫동안 지속적으로 발현되어 방충성능이 우수한 혼섬사를 제공하는 것이다.The object of the present invention is that the blended yarn has an appropriate strength, can be dyed, has excellent morphological stability because the segments of the composite fiber constituting the blended yarn are not easily divided, and has excellent insect-repellent performance for a long time. Is to provide.

When manufacturing a composite fiber with excellent insect repellency by composite spinning, (i) one high melting point polymer segment (B) selected from polyester and nylon and (ii) a material containing a natural insect repellent are mixed on the cross section of the composite fiber. The low-melting-point polymer segments (A) with a melting point of 200°C or less are arranged alternately, and the low-melting-point polymer segment (A) is arranged to prevent the cross-sectional shape of the composite fiber from becoming unstable due to the division of the segments constituting the composite fiber. ) Are (i) a straight portion extending from the center point of the cross-section of the composite fiber to a length of 2/3 to 3/4 of the cross-section radius of the composite fiber in the direction of the outer peripheral surface of the cross-section of the composite fiber; and (ii) the straight portion adjacent to the outer peripheral surface of the cross-section of the composite fiber.

Adjust it to less than.

본 발명은 혼섬사를 구성하는 오렌지형 복합섬유의 원사 단면이 분할되지 않으면서도 천연 방충제 함유 물질이 혼합된 저융점 폴리머 세그멘트(A)들이 원사 표면으로 노출되어 있어서 양호한 방충효과를 오랫동안 발현하고, 복합섬유 전체 표면적의 50% 이상이 나일론 또는 폴리에스터인 고융점 폴리머 세그멘트로 이루어져 염색도 가능하다.The present invention expresses a good insect repellent effect for a long time because the low melting point polymer segments (A) mixed with a natural insect repellent-containing material are exposed to the surface of the yarn while the yarn cross section of the orange composite fiber constituting the blended yarn is not divided.

It consists of a straight portion extending to a length of 2/3 to 3/4 of the radius; and (ii) a curved portion in the shape of a fallopian tube extending from one end of the straight portion adjacent to the outer peripheral surface of the cross-section of the composite fiber to the outer peripheral surface of the cross-section of the composite fiber.

상기 고융점 폴리머 원사 및 복합섬유의 고융점 폴리머 세그멘트(B)를 구성하는 폴리머 일례로는 폴리트리메틸렌테레프탈레이트, 폴리부틸렌테레프탈레이트, 폴리에틸렌테레프탈레이트 등과 같은 폴리에스터계 폴리머 또는 나일론 6, 나일론 66 등과 같은 폴리아미드계 나일론 폴리머가 사용되고, 상기 복합섬유의 저융점 폴리머 세그멘트(A)를 구성하는 폴리머 일례로는 폴리올레핀계 폴리머, 융점이 200℃ 이하인 공중합 폴리에스테르 또는 폴리락틱에시드(PLA) 폴리머가 사용될 수 있다.Examples of polymers constituting the high melting point polymer segment (B) of the high melting point polymer yarn and composite fibers include polyester polymers such as polytrimethylene terephthalate, polybutylene terephthalate, polyethylene terephthalate, or nylon 6, nylon 66 Polyamide-based nylon polymer such as, etc., is used, and examples of the polymer constituting the low-melting-point polymer segment (A) of the composite fiber include polyolefin-based polymer, copolymerized polyester or polylactic acid (PLA) polymer having a melting point of 200° C. or less. I can.

고융점 폴리머 원사 : 오렌지형 복합섬유의 혼섬 비율이 50~70중량% : 50~30중량%인 것이 방충성 향상 등에 바람직하다.It is preferable that the blend ratio of the high melting point polymer yarn: the orange composite fiber is 50 to 70% by weight: 50 to 30% by weight to improve insect repellency.

복합섬유 단면 상에있는 고융점 폴리머 세그멘트(B) 및 저융점 폴리머 세그멘트(A) 각각의 개수가 4~16개인 것이 바람직하다.It is preferable that the number of each of the high melting point polymer segment (B) and the low melting point polymer segment (A) on the cross section of the composite fiber is 4 to 16.

친환경성을 향상시키기 위해서 상기 고융점 폴리머 세그멘트(B)를 폴리트리메틸렌테레프탈레이트로 구성하고, 저융점 폴리머 세그멘트(A)를 폴리락틱에시드(PLA)로 구성하는 것이 바람직하다.In order to improve environment-friendliness, it is preferable that the high melting point polymer segment (B) is composed of polytrimethylene terephthalate, and the low melting point polymer segment (A) is composed of polylactic acid (PLA).

천연 방충제로는 유카리레몬, 레몬그라스, 시트로넬라, 오렌지 스위트, 비터, 계피, 클로브, 캐리커러웨이, 시나몬리프, 페퍼민트, 알벤시스민트, 베티바, 페니로열민트, 티트리, 니아우리, 히노키, 히바, 시더우드 아틀라스, 시더우드 버지니아, 홀리프 등이 사용될 수 있다.Natural insect repellents include Yukari Lemon, Lemongrass, Citronella, Orange Sweet, Bitter, Cinnamon, Clove, Caricature, Cinnamon Leaf, Peppermint, Albencis Mint, Vetiba, Penny Royal Mint, Tea Tree, Niauri, Hinoki , Hiba, Cedarwood Atlas, Cedarwood Virginia, Hollyf, etc. can be used.

저융점 폴리머 세그멘트(A)들이 상기의 직선부와 곡선부로 구성되기 때문에 복합섬유 단면상에서 상기 고융점 폴리머 세그멘트(B)의 복합섬유 동심원상 최대거리(d1)가 복합섬유 외주면상에 노출된 곡선 거리(d2)가 보다 더 길게 형성되고, 그로 인해 복합섬유를 구성하는 저융점 폴리머 세그멘트(A)들과 고융점 폴리머 세그멘트(B)들이 쉽게 분할되지 않아 복합섬유의 형태안정성이 향상된다.Since the low melting point polymer segments (A) are composed of the above straight and curved portions, the maximum concentric distance (d1) of the composite fiber of the high melting point polymer segment (B) on the cross section of the composite fiber is the curved distance exposed on the outer peripheral surface of the composite fiber. (d2) is formed longer, and thus the low-melting-point polymer segments (A) and high-melting-point polymer segments (B) constituting the composite fiber are not easily divided, improving the shape stability of the composite fiber.

본 발명은 도 1에 도시된 바와 같이 복합섬유 전체 표면적 대비 저융점 폴리머 세그멘트(A)들의 총 표면적 비율이 50% 미만이며, 그로 인해 고융점 폴리머 세그멘트(B)들이 복합섬유 외표면에 보다 많이 노출되어 분산염료 또는 산성염료에 의한 염색이 가능해 진다.In the present invention, as shown in FIG. 1, the ratio of the total surface area of the low melting point polymer segments (A) to the total surface area of the composite fiber is less than 50%, and thus, the high melting point polymer segments (B) are exposed more to the outer surface of the composite fiber. This makes it possible to dye with disperse dyes or acid dyes.

상기 천연 방충제 함유 물질은 천연 방충제가 담지되어 있는 무기 담지체이거나 천연 방충제가 담겨져 있는 마이크로 캡슐 등이다.The natural insect repellent-containing material is an inorganic carrier containing a natural insect repellent or a microcapsule containing a natural insect repellent.
