Description
본 발명은 볼륨감과 청량감이 우수한 레이온 필라멘트-열융착 합성 필라멘트 복합섬유(이하 "레이온-열융착 필라멘트 복합섬유"라고 약칭한다) 및 이로 제조된 원단에 관한 것이다.The present invention relates to a rayon filament-heat-sealed synthetic filament composite fiber (hereinafter referred to as "rayon-heat-sealed filament composite fiber") excellent in volume and coolness, and a fabric made therefrom.
보다 구체적으로, 본 발명은 볼륨감과 청량감을 동시에 발현할 수 있는 레이온-열융착 필라멘트 복합섬유 및 이를 경사의 전부 또는 일부나 위사의 전부 또는 일부로 사용하여 제조된 원단에 관한 것이다.
More specifically, the present invention relates to a rayon-heat-sealed filament composite fiber capable of expressing a sense of volume and a refreshing feeling at the same time and a fabric manufactured by using all or part of the warp yarn or all or part of the weft yarn.
의류용 원단의 경우에는 우수한 볼륨감과 청량감이 요구되고 있으나, 종래 기술로서는 볼륨감과 청량감이 동시에 우수한 원단을 제조하는데에는 한계가 있었다.In the case of the fabric for clothes, excellent volume and refreshing feeling are required, but there is a limitation in manufacturing a fabric having excellent volume and refreshing feeling at the same time.
구체적으로, 면 방적사 또는 양모 방적사의 경우에는 어느정도의 볼륨감은 얻을 수 있으나 청량감이 부족한 문제점이 있었다.Specifically, in the case of cotton yarn or wool yarn we can get some sense of volume, but there was a problem of lack of cooling.
또한, 합성섬유 필라멘트의 경우에는 어느정도의 청량감을 얻을 수 있으나 볼륨감이 부족한 문제점이 있었다.In addition, in the case of synthetic fiber filament can be obtained a certain degree of cooling feeling, there was a problem of lack of volume.
또한, 면 방적사 또는 양모 방적사와 합성섬유 필라멘트를 합사 또는 연사한 복합섬유의 경우에는 복합섬유내 면 방적사 또는 양모 방적사가 효과적으로 복합섬유 표면으로 부출하지 못해서 만족스런 볼륨감을 얻을 수 없으며, 청량감도 합성섬유 필라멘트 단독 사용시 보다 떨어지는 문제가 있었다.
In addition, in the case of a composite fiber in which yarn or yarn is spun or twisted with cotton spun yarn or wool spun yarn, the cotton spun yarn or wool spun yarn in the composite fiber is not effectively fed to the surface of the composite fiber, and a satisfactory volume feeling is not obtained. There was a problem of lowering when using the filament alone.
이와같은 종래의 문제점들을 해결할 수 있도록, 본 발명에서는 볼륨감과 청량감이 동시에 우수한 레이온-열융착 필라멘트 복합섬유 및 이로 제조된 원단을 제공하는 것을 과제로 한다.
In order to solve such problems in the prior art, the present invention is to provide a rayon-heat-sealed filament composite fiber and a fabric made therefrom excellent in volume and coolness at the same time.
이와같은 과제를 달성하기 위해서, 본 발명에서는 (ⅰ) 융점이 서로 상이한 2종의 섬유형성성 폴리머들이 원사단면 상에서 열융착되어있는 열융착 합성 필라멘트와 (ⅱ) 상기 2종의 섬유형성성 폴리머들 중에서 융점이 상대적으로 낮은 1종의 섬유형성성 폴리머와 열융착되어 있는 레이온 필라멘트로 구성되며, 상기 2종의 섬유형성성 폴리머들 중 적어도 하나의 섬유형성성 폴리머 내에 무기입자가 함유되어 볼륨감과 청량감이 우수한 레이온 필라멘트-열융착 합성 필라멘트 복합섬유 및 이로 제조된 원단을 제공한다.

Figure 2 is a cross-sectional view of a heat-sealed synthetic filament in the form of side by side (side by side) used in the production of rayon-heat-sealed filament composite fiber according to the present invention.
이하, 첨부한 도면 등을 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 레이온-열융착 필라멘트 복합섬유는 (ⅰ) 융점이 서로 상이한 2종의 섬유형성성 폴리머(A와 B 또는 C와 S)들이 원사 단면상에서 열융착되어 있는 열융착 합성 필라멘트와 (ⅱ) 레이온 필라멘트로 구성된다.The rayon-heat-sealed filament composite fiber according to the present invention comprises (i) a heat-sealed synthetic filament in which two kinds of fiber-forming polymers having different melting points (A and B or C and S) are heat-sealed on a yarn cross-section, and (ii) ) Consists of rayon filament.
상기 열융착 합성 필라멘트는 도 1 내지 도 2에 도시된 바와 같이 2종의 섬유형성성 폴리머(A와 B 또는 C와 S)들이 원사 단면상에서 시스-코어(Sheath core) 형태 또는 사이드 바이 사이드(Side by side) 형태로 열융착되어 있는 단면구조를 갖는다.The heat-sealed synthetic filament is a two-fiber forming polymer (A and B or C and S) in the form of a sheath-core (Sheath core) or side-by-side (Side) on the yarn cross-section as shown in FIG. It has a cross-sectional structure that is heat-sealed in the form of by side).
도 1 내지 도 2는 열융착 합성 필라멘트의 단면도이다.1 to 2 are cross-sectional views of heat-sealed synthetic filaments.
열융착 합성 필라멘트의 단면형태가 도 2와 같은 사이드 바이 사이드 형태인 경우에는 레이온 필라멘트의 열융착이 잘 일어나도록 시스(S) 부분을 융점이 상대적으로 낮은 섬유형성성 폴리머로 형성하는 것이 바람직하다.When the cross-sectional shape of the heat-sealed synthetic filament is a side-by-side shape as shown in FIG. 2, it is preferable to form the sheath (S) portion of the fiber-forming polymer having a relatively low melting point so that the thermal fusing of the rayon filament occurs well.
상기 2종의 섬유형성성 폴리머들 간의 융점차이는 30~130℃인 것이 열융착 합성 필라멘트의 잠재권축성을 향상시켜 레이온 필라멘트를 원사 표면으로 효과적으로 부출시키고, 레이온 필라멘트와 열융착 합성 필라멘트를 효과적으로 융착시키는데 바람직하다.The melting point difference between the two fiber-forming polymers is 30 to 130 ° C. to improve the latent crimpability of the heat-sealed synthetic filament, thereby effectively blowing the rayon filament to the yarn surface, and effectively fusing the rayon filament and the heat-sealed synthetic filament. It is preferable to.
상기 2종의 섬유형성성 폴리머들은 융점이 상이한 동일계 폴리머 이거나 융점이 상이한 이성질계 폴리머로서, 나일론계 폴리머, 폴리에스테르계 폴리머 또는 폴리프로필렌계 폴리머 등이다.The two fiber-forming polymers are in-situ polymers having different melting points or isomeric polymers having different melting points, such as nylon polymers, polyester polymers, or polypropylene polymers.
상기 열융착 합성 필라멘트를 구성하는 2종의 섬유형성성 폴리머들 중 적어도 하나의 섬유형성성 폴리머에는, 다시말해 2종의 섬유형성성 폴리머 모두 또는 2종의 섬유형성성 폴리머 중 1종의 섬유형성성 폴리머에는, 청량감을 향상시킬 목적으로 무기입자가 함유되어 있다.At least one of the fiber-forming polymers of the two fiber-forming polymers constituting the heat-sealed synthetic filament, that is, all of the two fiber-forming polymers or one of the two fiber-forming polymers The polymer contains inorganic particles for the purpose of improving the refreshing feeling.
상기 무기입자로는 산화티탄, 황산바륨, 산화아염, 실리카, 알루미나 수화물 또는 이들의 혼합물 등이 사용될 수 있다.Titanium oxide, barium sulfate, zinc oxide, silica, alumina hydrate or a mixture thereof may be used as the inorganic particles.
섬유형성성 폴리머내 무기입자의 함유량은 섬유형성성 폴리머 전체중량대비 1~10 중량%인 것이 바람직하다.The content of the inorganic particles in the fiber-forming polymer is preferably 1 to 10% by weight based on the total weight of the fiber-forming polymer.
상기 함유량이 1 중량% 미만이면 청량감 개선효과가 미미하게 되고, 10 중량%를 초과하게 되면 제사 조업성이 나빠질 우려가 있다.If the content is less than 1% by weight, the effect of improving the refreshing feel is insignificant, and if the content is more than 10% by weight, there is a concern that deterioration of the manufacturing operation is deteriorated.
상기 무기입자의 평균직경은 실험결과 0.15~2 ㎛인 것이 청량감 향상에 바람직하다.The average diameter of the inorganic particles is preferably 0.15 ~ 2 ㎛ as a result of the experiment to improve the refreshing feeling.
본 발명에 따른 레이온-열융착 필라멘트 복합섬유는 레이온 섬유와 열융착섬유를 합사, 연사 또는 커버링 한 후에 열판 또는 열튜브를 통과시키면서 상기 열융착 필라멘트 복합섬유를 구성하는 2종의 섬유형성성 폴리머들 중에서 융점이 상대적으로 낮은 섬유형성성 폴리머(A 또는 S)를 용융시켜 상기 복합섬유내 레이온 필라멘트와 열융착 합성 필라멘트 상호간을 열융착시키는 방법 등으로 제조할 수 있다.Rayon-heat-sealed filament composite fiber according to the present invention comprises two types of fiber-forming polymers constituting the heat-sealed filament composite fiber while passing through a hot plate or a heat tube after weaving, twisting or covering the rayon fiber and the heat-sealed fiber. It can be prepared by melting a relatively low melting point fiber-forming polymer (A or S) in the heat-bonding between the rayon filament and the heat-sealed synthetic filament in the composite fiber.
그로인해, 상기 레이온 필라멘트는 상기 열융착 합성 필라멘트와 열융착 되어진다.Thereby, the rayon filament is thermally fused with the thermal fusion synthetic filament.
상기 레이온 필라멘트와 열융착 합성 필라멘트의 복합 비율(중량기준)은 레이온 필라멘트 20~80 중량%와 열융착 합성 필라멘트 80~20 중량%인 것이 청량감과 볼륨감을 동시에 향상시키는데 바람직하다.The composite ratio (weight basis) of the rayon filament and the heat-sealed synthetic filament is 20 to 80% by weight of the rayon filament and the 80 to 20% by weight of the heat-sealed synthetic filament is preferable to improve the refreshing feel and the volume.
레이온 필라멘트 복합비율이 20 중량% 미만인 경우에는 볼륨감이 저하되고, 80 중량%를 초과하는 경우에는 청량감이 저하될 수 있다.If the rayon filament composite ratio is less than 20% by weight, the feeling of volume may be lowered, and if it exceeds 80% by weight, the cooling feeling may be reduced.
레이온 필라멘트와 열융착 합성 필라멘트의 복합비율은 상기 범위내에서 용도 등에 따라 적절하게 조절된다.The composite ratio of the rayon filament and the heat-sealed synthetic filament is appropriately adjusted according to the use and the like within the above range.
본 발명에서 볼륨감이 향상되는 원리를 살펴보면, 레이온 필라멘트의 열수축율 보다는 열융착 합성 필라멘트의 열수축율이 상대적으로 높기 때문에, 열처리시 열수축율이 상대적으로 큰 열융착 합성 필라멘트가 보다 많이 수축되면서 열수축율이 상대적으로 작은 레이온 필라멘트를 레이온-열융착 필라멘트 복합섬유의 표면으로 부출시키기 때문에 볼륨감이 향상된다.Looking at the principle of improving the sense of volume in the present invention, since the heat shrinkage of the heat-sealed synthetic filament is relatively higher than the heat shrinkage of the rayon filament, the heat shrinkage rate as the heat-shrinkage synthetic filament relatively large shrinkage during heat treatment The relatively small rayon filament is ejected to the surface of the rayon-heat-sealed filament composite fiber, thereby improving the volume.
