Description

새로운 체온조절 셀룰로오스 섬유{.}New Thermoregulated Cellulose Fibers {.}

본 발명은 셀룰로오스계의 체온조절용 섬유에 관한 것으로, 보다 상세하게는 셀룰로오스에 열역학적 성질을 지니는 물질을 첨가, 혼합, 용해, 방사하여 얻어지는 셀룰로오스계 섬유로서 첨가된 물질이 열(체온)에 의해 상전이를 일으킴에 따라, 체온이 조절되는 체온조절 셀룰로오스 섬유 및 그 제조방법에 관한 것이다.The present invention relates to a cellulose-based fiber for controlling the temperature, and more particularly, a substance added as a cellulose-based fiber obtained by adding, mixing, dissolving, and spinning a substance having thermodynamic properties to cellulose, thereby causing phase change by heat (body temperature). According to the present invention, the present invention relates to a thermoregulated cellulose fiber whose body temperature is controlled, and a method of manufacturing the same.

폴리에틸렌글리콜(PEG)과 폴리에틸렌옥사이드(PEO)는 인간의 피부온도인 36℃ 근처에서 상전이(phase change), 즉 고체에서 액체로 변하거나 다시 액체에서 고체로 변한다. 이러한 성질을 이용하여 이들을 용해시켜 피복(fabric)에 도포(coating)함으로써 스키복, 운동복 등의 야외복에 추위나 더위로부터 체온을 조절하는 데에 쓰이고 있다.Polyethyleneglycol (PEG) and polyethylene oxide (PEO) are phase change, ie, from solid to liquid or back to liquid again, near the skin temperature of 36 ° C. By using these properties, these are dissolved and coated on a fabric, which is used to control body temperature from cold or heat in outdoor clothes such as ski clothes and sports clothes.

이에 본 발명자는 PEG 또는 PEO를 셀룰로오스(폐레이욘)에 첨가하여 새로운 기능성(체온조절) 셀룰로오스 섬유를 제조하는 연구를 거듭한 결과 기계적인 물성이 우수하고 인간의 체온 변화에 따라 상전이를 일으키는 새로운 셀룰로오스 섬유를 개발하기에 이르렀다.Therefore, the present inventors have repeatedly studied the manufacture of new functional (thermoregulated) cellulose fibers by adding PEG or PEO to cellulose (pulmonary rayon). As a result, new cellulose is excellent in mechanical properties and causes phase transition according to changes in human body temperature. It has led to the development of fibers.

본 발명의 목적은 기계적인 물성이 우수한, 따라서 의복용 섬유로 적합한 셀룰로오스 섬유 및 그 제조방법을 제공하는 것이다.It is an object of the present invention to provide a cellulose fiber excellent in mechanical properties and thus suitable for garment fibers and a method for producing the same.

본 발명의 다른 목적은 폐기물(폐레이욘, 폐면)을 재활용하고 또한 일반적인 섬유의 기계적인 성질외에 체온조절 기능성이 부여된 새로운 셀룰로오스 섬유 및 그 제조방법을 제공하는 것이다.It is another object of the present invention to provide a new cellulose fiber and a method for producing the same, in which waste (waste rayon, waste cotton) is recycled and endowed with thermoregulatory functionality in addition to the mechanical properties of ordinary fibers.

본 발명의 이러한 목적은 셀룰로오스와 PEG 또는 PEO를 함께 공용용매에 녹이고 이 용액을 응고액에 토출, 권취함으로써 달성될 수 있다.This object of the present invention can be achieved by dissolving cellulose and PEG or PEO together in a common solvent and discharging and winding the solution in a coagulation solution.

PEG와 PEO는 물이나 유기용매에 용해되어 식품첨가제, 식품포장재, 치약, 화장품, 약품 등에 첨가제로 쓰이고 있고, 분자량은 200내지 20,000 정도를 가지며 분자량에 따라 각기 다른 용융온도를 갖는다. 분자량이 1,000일 때 이들은 36℃내지 37℃에서 열에 의해 용융(고체에서 액체로)되며 그 이하온도가 되면 다시 결정화(액체에서 고체로)한다.PEG and PEO are dissolved in water or organic solvents and used as additives in food additives, food packaging materials, toothpaste, cosmetics, medicines, etc., and have molecular weights of about 200 to 20,000 and different melting temperatures depending on the molecular weight. When the molecular weight is 1,000, they are melted by heat (from solid to liquid) at 36 ° C. to 37 ° C. and then crystallized again (from liquid to solid) at temperatures below.

본 발명의 특징은 PEG 또는 PEO의 상전이 성질을 이용하여 몸이 더워지면 인체의 열을 빼앗아(흡열) 자체(PEG 또는 PEO)는 부드러워졌다가 인체가 다시 추워지면 자체의 열을 인체에 공급하면서(방열) 자체는 굳어지며 인체는 더워지는 원리에 의해, 인체는 이들 상전이 물질로 인해 체온조절이 가능하여 지는 것이다.The feature of the present invention is to take advantage of the phase transition properties of PEG or PEO to take away the heat of the human body when the body becomes hot (endothermic) itself (PEG or PEO) is softened while supplying its own heat to the human body when the body becomes cold again ( Heat dissipation) By itself hardens and the body warms, the human body is able to control the body temperature due to these phase change substances.

본 발명의 다른 특징은 상전이 성질을 갖지 않는 셀룰로오스에 상전이를 나타내는 물질을 첨가하여 상전이를 나타내는 새로운 셀룰로오스계 섬유가 제조된다는 것이다.Another feature of the present invention is that a new cellulose-based fiber exhibiting phase transition is prepared by adding a phase transition material to a cellulose having no phase transition property.

본 발명의 체온조절 셀룰로오스 섬유를 제조하기 위해서는 셀룰로오스와 상전이 물질에 대한 공용용매의 발굴 및 선택이 중요하다. 연구결과 가성소다(NaOH)가 약간(6-8%) 포함된 물이 우수한 공용용매임과 이 용매안에서 두 물질(셀룰로오스와 PEG 또는 셀룰로오스와 PEO)은 상분리를 일으키지 않고 서로 잘 섞여 있음을 발견하였다.In order to manufacture the thermoregulated cellulose fiber of the present invention, the discovery and selection of a common solvent for cellulose and a phase change material is important. The study found that water containing a small amount (6-8%) of caustic soda (NaOH) was a good cosolvent and that the two materials (cellulose and PEG or cellulose and PEO) were well mixed with each other without causing phase separation. .

본 발명의 체온조절 셀룰로스 섬유를 제조하는 데에 있어 셀룰로오스로는 폐레이욘, 폐면 또는 펄프가 사용될 수 있다. 그러나 폐레이욘을 용해시키는 데에는 전처리(가성소다수용액에 담가 두는)과정이 필요하지 아니하나 폐면과 펄프는 약 12시간 내지 24시간의 전처리과정이 필요하다.In preparing the thermoregulated cellulose fibers of the present invention, waste rayon, waste cotton or pulp may be used as the cellulose. However, dissolving waste rayon does not require pretreatment (soaking in caustic soda solution), but waste cotton and pulp require about 12 to 24 hours of pretreatment.

본 발명의 체온조절 셀룰로오스 섬유는 방사용액중의 셀룰로오스와 상전이 물질의 혼합비율에 따라 약간 다른 상전이 온도를 나타낸다. 대체로 방사용액에는 20내지 50중량%의 상전이 물질이 포함된다. 상전이 물질의 비율이 20이하가 되면 상전이 효과가 없고, 50이상이 되면 섬유형성이 어려웠다. 또한 비율이 20에서 50사이에서 상전이 온도는 36.5℃에서 34.1℃로 변하였다. 이는 대체로 성인보다 체온이 높은 어린아이들과 어린이보다 보통 1내지 1.5℃ 낮은 노인들을 위해 각기 다른 섬유를 제공할 수 있음을 의미한다.The thermoregulated cellulose fibers of the present invention exhibit slightly different phase transition temperatures depending on the mixing ratio of cellulose and the phase change material in the spinning solution. In general, the spinning solution contains 20 to 50% by weight of phase change material. When the ratio of the phase change material is 20 or less, the phase change is not effective, and when it is 50 or more, fiber formation is difficult. In addition, the phase transition temperature was changed from 36.5 ° C. to 34.1 ° C. at a ratio of 20 to 50. This generally means that different fibers can be provided for children with higher body temperatures than adults and older people who are usually 1 to 1.5 ° C lower than children.

다음 실시예는 본 발명을 더욱 구체적으로 설명하기 위해 예시한 것에 지나지 않으며, 본 발명은 실시예에 의해 한정되는 것은 아니다.The following examples are merely illustrated to illustrate the present invention in more detail, the present invention is not limited by the examples.
