Description
본 발명은 접촉냉감이 우수한 해도형 복합섬유에 관한 것으로 접촉냉감이 우수하면서도 해도형으로 형성되어 염색성이 우수한 접촉냉감이 우수한 해도형 복합섬유에 관한 것이다.The present invention relates to a sea-island type composite fiber with excellent contact cooling feeling, and relates to a sea-island type composite fiber with excellent contact cooling feeling, which is formed in a sea-island type and has excellent dyeability.
의복은 사계절 기후에 따라 다양한 종류가 있으며, 특히 여름철에서 강한 햇빛과 더운 기온을 피하기 위해 얇고 통풍이 우수한 원단을 사용한다. 여름용 의복은 단순히 청량감을 위해 통기성을 높이거나 가벼운 소재의 개발에는 한계가 있어 수분과 결합하여 흡열하는 기능성 물질을 이용하여 직접적인 냉감성을 갖는 섬유원단이 많이 개발되고 있다.There are various types of clothes according to the climate of the four seasons, and especially in summer, thin and breathable fabrics are used to avoid strong sunlight and hot temperatures. For summer clothing, there is a limit to simply increasing air permeability for a sense of coolness or developing lightweight materials, so many textile fabrics with direct cooling sensation are being developed using functional materials that absorb heat by combining with moisture.
종래의 냉감기능을 갖는 섬유원단은 섬유 또는 원단에 이산화티탄, 산화 아연 등의 무기물을 함유시켜 태양광의 자외선과 적외선을 반사 및 차단하여 냉감기능을 갖는 기술이 많이 사용되고 있다.Conventional textile fabrics having a cooling function include inorganic substances such as titanium dioxide and zinc oxide in fibers or fabrics to reflect and block ultraviolet rays and infrared rays of sunlight, and technologies having a cooling function are widely used.
이러한 종래기술로 대한민국 특허공개 제2001-91286호에서는 태양광반사 특성에 의한 냉감 효과를 갖는 섬유, 좀더 상세하게는 태양광을 흡수하지 않고, 외부로 모두 반사하는 특성을 지닌 티탄산아연마그네슘을 함유함으로써 섬유 자신의 온도 상승을 억제하여 냉감효과를 갖는 섬유에 관한것으로, 산화아연-산화마그네슘-이산화티탄 3성분을 고온에서 소결 처리하여 복합산화물인 티탄산 아연마그네슘(ZMT)을 제조하고, 이를 혼입하여 자외선을 효율 좋게 반사함으로써 태양광 에너지의 흡수를 방지하여 냉감효과를 지닌 새로운 섬유 및 그 첨가물이 제안된 바 있다.As such a prior art, Korean Patent Publication No. 2001-91286 discloses a fiber having a cooling effect by reflecting sunlight, and more specifically, zinc magnesium titanate having a characteristic of reflecting all externally without absorbing sunlight. It relates to a fiber that has a cooling effect by suppressing the temperature rise of the fiber itself. Zinc oxide-magnesium oxide-titanium dioxide is sintered at high temperature to produce a composite oxide, zinc magnesium titanate (ZMT), which is mixed with ultraviolet rays. A new fiber and additives thereof having a cooling effect by preventing absorption of solar energy by efficiently reflecting the fiber have been proposed.
그러나 상기와 같이 무기물을 사용하여 자외선을 통한 냉감기능은 태양광이 없는 실내에서는 아무런 기능을 하지 못하며, 열이 복사되는 적외선 차단에 있어서는 미흡한 단점이 있었다. 또한, 외부의 열이 흡수되는 것을 차단하는 기능일 뿐 체내의 열을 외부로 방출시키는 기능은 미흡하고, 격렬한 운동시 발생하는 땀에 의해 젖은 상태에서는 냉감성을 느끼기가 더욱 어렵다.However, the cooling function through ultraviolet rays using inorganic materials as described above does not function at all in a room without sunlight, and there is an insufficient disadvantage in blocking infrared rays from which heat is radiated. In addition, the function of blocking the absorption of external heat is insufficient, and the function of dissipating heat from the body to the outside is insufficient, and it is more difficult to feel a sense of coolness in a wet state due to sweat generated during intense exercise.
따라서, 실내외에서 냉감 기능을 갖게하기 위해 기능성 물질이 함유된 냉감성을 갖는 섬유원단이 개발된 것으로 대한민국 특허등록 제10-897866호에서는 유기산 또는 이의 알칼리염, 페퍼민트오일, 호호바오일, 유기 바인더 및 잔량의 정제수를 포함하여 이루어지는 냉감 기능성 조성물을 제조하여 코팅시킨 냉감원단이 제안되었으며, 대한민국 특허공개 제2013-0013477호에는 1,2차 모노머, 잠열물질, 천연오일, 천연당류, 조핵제, 물을 혼합한 1차 조성물에 항균제, 유기 바인더 등을 혼합한 2차 조성물로 냉감 기능성 조성물을 제조하여 코팅한 냉감원단이 제안되었다.Therefore, in order to have a cooling function indoors and outdoors, a textile fabric with cooling properties containing functional materials has been developed, and in Korean Patent Registration No. 10-897866, organic acids or alkali salts thereof, peppermint oil, jojoba oil, organic binders, and remaining amounts A cooling fabric coated with a cooling functional composition comprising purified water has been proposed, and Korean Patent Publication No. 2013-0013477 discloses a mixture of primary and secondary monomers, latent heat materials, natural oil, natural sugars, nucleating agent, and water. A cooling fabric coated by preparing a cooling-feeling functional composition with a secondary composition in which an antibacterial agent, an organic binder, etc. are mixed with one primary composition has been proposed.
하지만, 이와 같은 냉감성을 갖는 섬유원단은 다수의 첨가제를 혼합하여 별도의 냉감제 조성물을 제조해야 함은 물론, 냉감 조성물을 원단 표면에 고착하기 위한 별도의 후가공 공정이 요구됨에 따라 생산에 상당한 시간과 비용이 소모됨은 물론, 마찰이나 세탁시 코팅된 냉감 조성물이 소실됨에 따라 냉감기능이 저하되는 문제가 있다.However, such a fiber fabric having a cool feeling requires a separate post-processing process for adhering the cool feeling composition to the surface of the fabric, as well as preparing a separate coolant composition by mixing a number of additives, so that a considerable amount of time is required for production. In addition to excessive cost, there is a problem in that the cooling function is deteriorated as the coated cooling composition is lost during friction or washing.
최근에는 열전도율이 높은 고분자 수지를 이용한 접촉냉감성이 높은 섬유원단이 개발되었다.Recently, a fiber fabric having high contact coolness using a polymer resin having high thermal conductivity has been developed.
상기 접촉냉감성이 높은 섬유원단은 열전도율이 높은 폴리아미드 수지를 이용한 복합섬유로 폴리아미드 수지를 시스부로 폴리에스테르 수지를 코어부로 사용하여 형성되는 시스-코어형 복합섬유이다.The fiber fabric with high contact coolness is a composite fiber using a polyamide resin having high thermal conductivity, and is a sheath-core type composite fiber formed by using a polyamide resin as a sheath part and a polyester resin as a core part.
그러나, 폴리아미드 수지와 폴리에스테르 수지로 형성되는 복합섬유는 단면구조로 염색성이 좋치 않으며, 폴리아미드 수지의 냉감 성능 향상에 제한이 있었다.However, composite fibers formed of a polyamide resin and a polyester resin have poor dyeability due to their cross-sectional structure, and there is a limitation in improving the cooling performance of the polyamide resin.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위해 발명된 것으로 접촉냉감성 향상을 위해 열전도율이 우수한 고밀도 폴리에틸렌 수지를 사용하면서 섬유의 물성을 유지하는 폴리에스테르 수지를 사용하여 접촉냉감이 우수한 해도형 복합섬유를 제공하는 것을 목적으로 한다.The present invention was invented to solve the problems of the prior art as described above, and is a sea-island type with excellent contact coolness by using high-density polyethylene resin with excellent thermal conductivity to improve contact coolness and using a polyester resin that maintains the physical properties of fibers.
