Description
본 발명은 냉감성이 향상된 원착 폴리에틸렌 섬유에 관한 것으로 구체적으로는 폴리에틸렌 섬유를 형성하는 폴리에틸렌 수지의 분자량을 제어하여 냉감성을 향상시키고 색상을 가지는 냉감성이 향상된 원착 폴리에틸렌 섬유에 관한 것이다. The present invention relates to dope-dyed polyethylene fibers with improved cold sensitivity. Specifically, it relates to dope-dyed polyethylene fibers with improved cold sensitivity that improve cold sensitivity and have color by controlling the molecular weight of the polyethylene resin forming the polyethylene fiber.
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 clothing depending on the climate of the four seasons, and especially in summer, thin, breathable fabrics are used to avoid strong sunlight and hot temperatures. There are limits to the development of lightweight materials or increased breathability for summer clothing simply for the sake of refreshing, so many textile fabrics with direct cooling properties are being developed using functional materials that combine with moisture and absorb heat.
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 with a cooling function have a cooling function by reflecting and blocking ultraviolet rays and infrared rays of sunlight by containing inorganic substances such as titanium dioxide and zinc oxide in the fiber or fabric.
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.With this prior art, Korean Patent Publication No. 2001-91286 contains fibers that have a cooling effect due to solar light reflection properties, and more specifically, zinc magnesium titanate, which does not absorb sunlight but reflects it to the outside. This relates to a fiber that has a cooling effect by suppressing the increase in temperature of the fiber itself. Zinc magnesium titanate (ZMT), a composite oxide, is manufactured by sintering three components of zinc oxide, magnesium oxide, and titanium dioxide at high temperature, and mixing it with ultraviolet rays. A new fiber and its additives that have a cooling effect by efficiently reflecting solar energy and preventing the absorption of solar energy 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, as described above, the cooling function through ultraviolet rays using inorganic materials does not function at all indoors without sunlight, and has the disadvantage of being inadequate in blocking infrared rays from which heat is radiated. In addition, its function is only to block external heat from being absorbed, but its function to release internal heat to the outside is insufficient, and it is more difficult to feel cold when wet 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 cold sensitivity containing functional substances was developed. In Korea Patent Registration No. 10-897866, organic acid or its alkali salt, peppermint oil, jojoba oil, organic binder and residual amount were used. A cooling fabric manufactured and coated with a cooling functional composition containing purified water was proposed, and in Korean Patent Publication No. 2013-0013477, primary and secondary monomers, latent heat substances, natural oil, natural sugars, nucleating agents, and water were mixed. A cool-sensitive fabric was proposed by manufacturing a cool-sensitive functional composition and coating it with a secondary composition that mixes an antibacterial agent, an organic binder, etc. with a primary composition.
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, fiber fabrics with such cooling properties not only require mixing multiple additives to produce a separate cooling agent composition, but also require a separate post-processing process to adhere the cooling composition to the fabric surface, which takes a considerable amount of time to produce. Not only is it expensive and expensive, but there is a problem that the cooling function is deteriorated as the coated cooling composition is lost during friction or washing.
최근에는 열전도율이 높은 고밀도 폴리에틸렌(HDPE) 수지를 이용하여 냉감성을 가지는 원사를 사용하는 섬유원단이 개발되었다.Recently, textile fabrics using cold-sensitive yarns using high-density polyethylene (HDPE) resin with high thermal conductivity have been developed.
대한민국 등록특허 제2110306호는 접촉냉감이 우수한 폴리에틸렌 원단에 관한 발명으로 폴리에틸렌사를 사용한 폴리에틸렌 원단에 대해 개시되어 있으며, 제2202592호는 냉감성 원단과 이를 위한 폴리에틸렌 원사에 관한 발명으로 고밀도 폴리에틸렌 수지의 높은 열전도율을 통해 냉감성을 가지는 폴리에틸렌 원사에 대해 개시되어 있다.Republic of Korea Patent No. 2110306 is an invention regarding a polyethylene fabric with excellent contact cooling properties and discloses a polyethylene fabric using polyethylene yarn, and No. 2202592 is an invention regarding a cold-sensitive fabric and polyethylene yarn for the same, and the high density polyethylene resin has a high Polyethylene yarn that has cold sensitivity through thermal conductivity is disclosed.
그러나, 종래의 폴리에틸렌 수지를 이용하는 냉감성 섬유는 단순히 열전도율을 높은 폴리에틸렌 섬유를 이용하는 것으로 기존의 폴리에틸렌 섬유와 큰 차이가 없었다.However, cold-sensitive fibers using conventional polyethylene resins were not significantly different from existing polyethylene fibers as they simply used polyethylene fibers with high thermal conductivity.
또한, 폴리에틸렌 섬유는 치밀한 결정 구조상 섬유로 제조 후에 염색이 어려운 문제가 있으며, 염색시 팽윤제, 촉염제등을 사용하여 염색하고 있으나, 선명성 및 견뢰도가 높지 않은 문제점이 있었다.In addition, polyethylene fiber has a dense crystal structure, so it is difficult to dye after manufacturing. Although it is dyed using a swelling agent and a dye stimulant, there is a problem in that the clarity and fastness are not high.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위해 발명된 것으로 폴리에틸렌 섬유에 포함되는 폴리에틸렌 수지의 냉감성을 위해 수평균분자량과 Z평균분자량을 제어하여 냉감성이 향상된 원착 폴리에틸렌 섬유를 제공하는 것을 목적으로 한다.The present invention was invented to solve the problems of the prior art as described above, and provides a dyed polyethylene fiber with improved cold sensitivity by controlling the number average molecular weight and Z average molecular weight for the cold sensitivity of the polyethylene resin contained in the polyethylene fiber.
