Description

접촉냉감 섬유시트{Cool-touch textile sheet}Cool-touch textile sheet}

본 발명은 접촉냉감 섬유시트에 관한 것으로 특히, 섬유시트의 일면인 피부접촉면에 열전도율이 높은 소재를 사용하여 체내의 열을 빠른 속도로 흡수 및 외부로 방출하여 접촉시 시원한 촉감을 형성하는 접촉냉감 섬유시트에 관한 것이다.The present invention relates to a cool-to-contact fiber sheet, and in particular, a cool-to-contact fiber that uses a material with high thermal conductivity on one side of the fiber sheet, the skin-contacting surface, to rapidly absorb and release heat from the body to the outside, creating a cool touch upon contact. It's about sheets.

일반적으로 열이 이동하는 방법으로는 매개체를 통하여 이루어지는 전도, 매개체 없이 직접적으로 이동하는 복사, 찬공기는 아래로 더운 공기는 위로 이동하여 순환하는 대류 현상에 의해 이동할 수 있다.Generally, heat moves through conduction through a medium, radiation, which moves directly without a medium, and convection, where cold air moves downward and hot air moves upward.

상기의 열의 근원이 되는 빛은 파장에 따라 자외선, 가시광선 및 적외선 등이 전체 파장의 90% 이상을 차지한다. Depending on the wavelength, the light that is the source of the above heat includes ultraviolet rays, visible rays, and infrared rays, accounting for more than 90% of the total wavelength.

자외선을 차단하는 방법으로 이산화티탄, 산화 아연 등의 무기물을 섬유에 방사 시 투입하거나, 자외선 흡수제를 섬유 표면에 코팅하여 원단으로 제조된 의복을 착용함으로서 90% 이상 차단 효과를 지니게 된다. As a way to block ultraviolet rays, inorganic substances such as titanium dioxide and zinc oxide are added to the fiber when spinning, or by coating the surface of the fiber with an ultraviolet absorber and wearing clothing made from the fabric, which has a blocking effect of more than 90%.

한편, 적외선에 있어서, 원적외선은 생체를 내부로부터 데워서 모세혈관을 비롯한 미세 동맥 및 정맥을 확장하여 전신의 혈액순환을 활성화 시키지만, 태양의 복사열에 가장 가까운 800 내지 1,400 nm 영역의 근적외선은 복사의 형태로 태양의 뜨거운 열이 전달되고, 침투력이 강해서 열선 역할을 하게 되어 의복 내부까지 침투하여 온도를 상승시켜 땀을 유발시킨다.Meanwhile, in infrared rays, far infrared rays warm the living body from the inside and expand fine arteries and veins, including capillaries, activating blood circulation throughout the body. However, near infrared rays in the 800 to 1,400 nm region, which are closest to the sun's radiant heat, are radiated in the form of radiation. The sun's hot heat is transmitted, and because of its strong penetrating power, it acts as a heat ray and penetrates into the inside of the clothing, raising the temperature and causing sweating.

특히, 여름에는 이러한 적외선의 복사열이 더 강하게 느껴지게 되기 때문에 한여름에 더위를 덜 느낄 수 있도록 하는 소재가 필요하다. In particular, since this infrared radiant heat is felt more strongly in the summer, materials that allow people to feel less heat in midsummer are needed.

상기의 이유로 얇고 밝은 원단으로 된 의복을 착용하면 시원하기는 하지만, 자외선이 통과되어 피부가 타게 된다. 반면, 두껍고 진한색의 원단으로 된 의복은 자외선이 차단되기는 하나, 근적외선 흡수율이 높아 의복 내부 온도가 상승하여 더위가 더욱 가중된다. For the above reasons, wearing clothes made of thin and bright fabrics may be cool, but UV rays will pass through and your skin will get burned. On the other hand, clothing made of thick, dark-colored fabric blocks ultraviolet rays, but has a high absorption rate of near-infrared rays, which increases the temperature inside the clothing, further aggravating the heat.

상기의 문제를 해결하기 위해 기존에는 흡습성이 양호한 천연섬유인 면이 이용되었는데, 이는 건조속도가 늦어 일정수분 이상 흡수하면 건조되지 않아 체온 상승을 유발시키게 된다.To solve the above problem, cotton, a natural fiber with good hygroscopicity, was previously used, but its drying speed is slow, so if it absorbs more than a certain amount of moisture, it does not dry, causing an increase in body temperature.

따라서, 여름에는 얇고 밝은 원단 외에도 어떤 색상이나 구조를 지니더라도 자외선뿐만 아니라 적외선도 차단되고, 더위를 느끼지 않도록 지속적인 냉감성이 부여된 원단의 필요성이 더욱 절실하다.Therefore, in the summer, in addition to thin and bright fabrics, there is an even more urgent need for fabrics that block not only ultraviolet rays but also infrared rays, no matter what color or structure they have, and are provided with constant coolness so that you do not feel hot.

종래의 냉감기능을 갖는 섬유시트는 섬유 또는 원단에 이산화티탄, 산화 아연 등의 무기물을 함유시켜 태양광의 자외선과 적외선을 반사 및 차단하여 냉감기능을 갖는 기술이 많이 사용되고 있다.Conventional fiber sheets 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 티탄산아연마그네슘(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 체내의 열을 배출하고 수분을 외부로 방출하는 기능성 소재의 개발이 필요하다.Therefore, the development of functional materials that dissipate heat from the body and release moisture to the outside is necessary.

본 발명에 따른 접촉냉감 섬유시트는 섬유시트 일면에 열전도율이 높은 소재를 형성하여 체내의 열을 빠른속도로 흡수 및 외부로 방출하여 접촉시 시원한 촉감을 형성하는 접촉냉감 섬유시트를 제공하는 것을 목적으로 한다.The purpose of the contact cooling fiber sheet according to the present invention is to provide a contact cooling fiber sheet that forms a material with high thermal conductivity on one side of the fiber sheet, absorbs heat inside the body at a rapid rate and releases it to the outside, thereby forming a cool touch upon contact. do.

또한, 섬유시트 표면층에서 흡수된 수분이 원단 이면층으로 일방향 전이되어 항상 건조한 착용감을 갖는 접촉냉감 섬유시트를 제공하는 것을 목적으로 한다.In addition, the purpose of the present invention is to provide a cool-to-contact fiber sheet that always has a dry feeling because moisture absorbed from the surface layer of the fiber sheet is transferred in one direction to the back layer of the fabric.

본 발명은 피부와 접해지는 표면층은 이면층으로 형성되는 접촉냉감 섬유시트에 있어서, 상기 표면층은 고밀도 폴리에틸렌 원사로 형성되는 도트(dot) 또는 줄무늬 형태의 소수부와 상기 소수부와 중첩되지 않는 친수성 원사로 형성되는 친수부로 형성되고, 상기 이면층은 친수성 원사를 포함하여 형성되며, 상기 표면층의 소수부는 표면층의 전체 면적의 70~90%로 형성되는 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.The present invention relates to a cool-contact fiber sheet in which the surface layer in contact with the skin is formed as a back layer, wherein the surface layer is formed of a dot- or stripe-shaped minority portion made of high-density polyethylene yarn and a hydrophilic yarn that does not overlap the minority portion. It is formed of a hydrophilic portion, the back layer is formed including hydrophilic yarn, and the hydrophobic portion of the surface layer is formed of 70 to 90% of the total area of the surface layer.

또한, 상기 친수성 원사는 나일론 6, 나일론 66, 레이온 중 어느 하나인 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, a contact cooling fiber sheet is provided, wherein the hydrophilic yarn is any one of nylon 6, nylon 66, and rayon.

또한, 상기 섬유시트는 이중직의 편물 또는 직물로 형성되는 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, the fiber sheet provides a contact cooling fiber sheet, characterized in that the fiber sheet is formed of a double-weave knit or fabric.

또한, 상기 이면층의 친수성 원사는 80중량%이상 함유하는 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, it provides a contact cooling fiber sheet, characterized in that the back layer contains more than 80% by weight of hydrophilic yarn.

또한, 상기 소수부와 친수부는 요철구조로 소수부가 친수부보다 볼록하게 형성되는 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, the hydrophobic portion and the hydrophilic portion provide a contact cooling fiber sheet, characterized in that the hydrophobic portion is formed to be more convex than the hydrophilic portion in a concavo-convex structure.

또한, 상기 고밀도 폴리에틸렌 원사는 산화아연이 함유되어 항균성을 갖는 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, the high-density polyethylene yarn contains zinc oxide and provides a cool-to-contact fiber sheet, characterized in that it has antibacterial properties.

또한, 상기 고밀도 폴리에틸렌 원사는 편평사로 편평비가 3 내지 6인 것을 특징으로 하는 접촉냉감 섬유시트를 제공한다.In addition, the high-density polyethylene yarn is a flat yarn and provides a contact cooling fiber sheet, characterized in that the aspect ratio is 3 to 6.

본 발명에 따른 접촉냉감 섬유시트는 피부접촉되는 표면층에 열전도율이 높은 고밀도 폴리에틸렌 원사로 형성되는 소수부를 통해 체내의 열을 빠르게 흡수 및 외부로 방출하여 접촉시 시원한 촉감을 형성하는 효과가 있다.The contact cooling fiber sheet according to the present invention has the effect of forming a cool touch upon contact by rapidly absorbing and discharging heat from the body to the outside through a hydrophobic portion formed of high-density polyethylene yarn with high thermal conductivity on the surface layer in contact with the skin.

또한, 표면층의 친수부를 통하여 일방향으로 수분이 빠르게 전이가 되어 표면층에서 항상 건조함을 가지는 효과가 있다.In addition, moisture is quickly transferred in one direction through the hydrophilic part of the surface layer, which has the effect of always keeping the surface layer dry.

The minority portion 110 is a component formed of high-density polyethylene yarn, and as the contact area increases, contact cooling properties improve. For the contact area, the high-density polyethylene yarn is preferably a flat yarn, and the long axis length (A) of the flat yarn is determined by It is preferable that the aspect ratio (A/B) of the length (B) of the orthogonal minor axis is 3 to 8. If the aspect ratio is less than 3, the effect of the flat yarn is small, and if the aspect ratio exceeds 8, the spinning fairness may be reduced.

또한, 본 발명에 따른 접촉냉감 섬유시트의 항균성을 위해 상기 고밀도 폴리에틸렌 원사는 산화아연이 함유되는 것이 바람직할 것이다.In addition, for the antibacterial properties of the cooling contact fiber sheet according to the present invention, it is preferable that the high-density polyethylene yarn contains zinc oxide.

상기 표면층(100)은 피부와 접촉되는 면으로 소수부(110)가 먼저 피부접촉될 수 있도록 상기 소수부(110)와 친수부(130)는 요철구조로 형성시키고, 소수부(110)가 친수부(130)보다 볼록하게 형성하여 접촉냉감성을 더욱 향상시킬 수 있을 것이다.The surface layer 100 is the surface in contact with the skin, and the hydrophobic portion 110 and the hydrophilic portion 130 are formed in a convex-convex structure so that the hydrophobic portion 110 can first contact the skin, and the hydrophobic portion 110 is formed with the hydrophilic portion 130. ), it will be possible to further improve contact cooling sensitivity by forming it more convexly.

상기 이면층(200)은 친수성 원사를 포함하여 형성되어 상기 친수부(130)를 통해 이동되는 수분을 저장한다.The back layer 200 is formed including hydrophilic yarn and stores moisture moving through the hydrophilic portion 130.

상기 표면층(100)의 친수부(130)를 형성하고, 이면층(200)에 함유되는 친수성 원사는 공정수분율이 높은 원사로 형성되는 것으로 나일론 6, 나일론 66, 레이온 중 어느 하나인 것을 사용할 수 있을 것이다.The hydrophilic yarn forming the hydrophilic portion 130 of the surface layer 100 and contained in the back layer 200 is formed of a yarn with a high process moisture content, and any one of nylon 6, nylon 66, and rayon can be used. will be.

상기 이면층의 수분흡입력을 위해 이면층의 친수성 원사 80중량%이상 함유하는 것이 바람직하며, 더욱 바람직하게는 이면층은 친수성원사 100중량% 형성되는 것이다.For the moisture absorption ability of the back layer, it is preferable that the back layer contains 80% by weight or more of hydrophilic yarns, and more preferably, the back layer is formed of 100% by weight of hydrophilic yarns.

상기와 같이 본 발명의 섬유시트는 표면층(100) 및 이면층(200)으로 구성되는 섬유시트로 제조 공정성을 위해 이중직의 편물 또는 직물로 형성되는 것이 바람직할 것으로 표면층은 고밀도 폴리에틸렌 원사 및 친수성 원사를 사용하고, 이면층은 친수성 원사로 사용하여 이면층의 친수성 원사를 연결사로 사용하여 이중직의 편물 또는 직물을 제조할 수 있을 것이다.As described above, the fiber sheet of the present invention is composed of a surface layer 100 and a back layer 200, and for manufacturing process, it is preferably formed of a double-weave knit or fabric. The surface layer is made of high-density polyethylene yarn and hydrophilic yarn. Using the back layer as a hydrophilic yarn, a double-weave knitted fabric or fabric can be manufactured by using the hydrophilic yarn of the back layer as a connecting yarn.

상기와 같이 친수성 원사를 사용하여 이면층(200)과 표면층(100)의 친수부(130)를 형성하는 편물 또는 직물을 제조하여 제조 공정성을 향상시킬 수 있을 것이다.As described above, the manufacturing process can be improved by manufacturing a knitted fabric or fabric that forms the hydrophilic portion 130 of the back layer 200 and the surface layer 100 using hydrophilic yarn.

상기와 같이 형성되는 본 발명에 따른 접촉냉감 섬유시트는 표면층(100)이 소수부(110)와 친수부(130)로 형성되고 이면층(200)이 친수성 원사로 형성되어 친수부를(130)를 통해 수분이 이면층으로 일방향 이동되는 특성으로 일방향 수분전이 특성을 위해 상기 친수부(130)의 폭은 0.5~5㎜로 형성되는 것이 바람직할 것이다.In the contact cooling fiber sheet according to the present invention formed as described above, the surface layer 100 is formed of a hydrophobic portion 110 and a hydrophilic portion 130, and the back layer 200 is formed of hydrophilic yarn through the hydrophilic portion 130. Since moisture moves in one direction to the back layer, it is preferable that the width of the hydrophilic portion 130 be formed to be 0.5 to 5 mm for unidirectional moisture transfer characteristics.

상기 친수부(130)는 소수부(110) 사이의 공간으로 섬유시트 표면층에 접촉된 수분을 흡수하여 이면층으로 전이시키는 통로 역할을 하는 곳으로 친수부(130)의 폭이 0.5㎜ 작으면 수분흡수가 원활하지 못하여 표면층이 축축해질 수 있으며, 친수부(130)의 폭이 5㎜보다 크면 수분이 흡수된 간극이 넓어 섬유시트 일면의 건조감이 저하될 수 있다.The hydrophilic portion 130 is a space between the hydrophobic portions 110 that serves as a passage to absorb moisture in contact with the surface layer of the fiber sheet and transfer it to the back layer. If the width of the hydrophilic portion 130 is less than 0.5 mm, moisture is absorbed. If the surface layer is not smooth, the surface layer may become wet, and if the width of the hydrophilic portion 130 is larger than 5 mm, the gap where moisture is absorbed is wide, and the dry feeling of one side of the fiber sheet may be reduced.

상기 표면층(100)은 도 3에서와 같이 도 3(a)와 같은 도트(dot) 형태, 또는 도 3(b)와 같은 줄무늬 형태, 또는 도 3(c)와 같은 격자무늬 형태 등 다양한 디자인된 문양으로 형성될 수 있고, 상기 친수부(130)는 수분흡수 시에 표면층에 친수부의 수분흡수에 따라 색상차이가 발생될 수 있다.As shown in FIG. 3, the surface layer 100 has various designs, such as a dot shape as in FIG. 3(a), a stripe shape as in FIG. 3(b), or a grid pattern shape as in FIG. 3(c). It may be formed in a pattern, and when the hydrophilic portion 130 absorbs moisture, a color difference may occur depending on the moisture absorption of the hydrophilic portion in the surface layer.

상기와 같이 형성되는 본 발명에 따른 접촉냉감 섬유시트는 고밀도 폴리에틸렌 원사로 형성되는 소수부(110)를 통해 접촉냉감성을 가지며, 도 2에서와 같이 소수부(110)와 친수부(130)이 형성된 섬유시트 표면층에 접하는 신체에서 발생된 수분은 소수부(110)의 발수성으로 흡수되지 못하고 2에서와 같이 친수부(130)에서 수분이 흡수되어 이면층(200)으로 수분이 이동된 후, 섬유시트 전방향으로 수분이 빠르게 흡수된다.The contact cooling fiber sheet according to the present invention formed as described above has contact cooling properties through the hydrophobic portion 110 formed of high-density polyethylene yarn, and is a fiber formed with the hydrophobic portion 110 and the hydrophilic portion 130 as shown in FIG. 2. Moisture generated from the body in contact with the surface layer of the sheet cannot be absorbed due to the water-repellent nature of the hydrophobic portion 110, and as shown in 2, moisture is absorbed in the hydrophilic portion 130 and moves to the back layer 200, and then flows in all directions of the fiber sheet. Moisture is absorbed quickly.

상기와 같이 섬유시트 이면층으로 흡수된 수분은 소수부(110)에 의해 섬유 표면층으로 전이되지 못하여 섬유시트 표면층서는 항상 건조감을 가지게 된다.As described above, the moisture absorbed into the back layer of the fiber sheet is not transferred to the surface layer of the fiber by the hydrophobic portion 110, so the surface layer of the fiber sheet always feels dry.
