相变材料（PCM）是能够在特定温度下转变相态（固体、液体、气体）并能提供潜热的材料。转变物质相态的过程称为相变过程，这时伴随着相变材料吸收或释放大量的潜热从而产生蓄冷或蓄热的功能。

Phase change materials (PCM) are materials that can change their phase (solid, liquid, gas) at a specific temperature and provide latent heat. The process of changing the phase of a substance is called a phase change process. During this process, the phase change material absorbs or releases a large amount of latent heat, thereby achieving the functions of cold or heat storage.

      PCM最早在美国国家航空航天局（NASA）登月计划中使用，是为宇航员服装系统开发舒适体感、平衡体温的新材料而研发，它能对温度进行自动调节，以应对太空极热极冷，温度剧烈变化的环境。这项技术始于1987年，NASA约翰逊航天中心与私营企业合作开发了用于舱外航天服尤其是宇航员手套的相变材料。在TRDC公司的协助下，NASA成功将含有相变微胶囊（mPCM）的纺织材料应用于宇航服。

PCM was first used in NASA's moon landing program in the United States. It was developed as a new material for the astronaut's clothing system to provide a comfortable feel and balance body temperature. It can automatically regulate temperature to cope with the extremely hot and cold, and the drastic temperature changes in space. This technology began in 1987. NASA's Johnson Space Center collaborated with private enterprises to develop phase change materials for extravehicular spacesuits, especially astronaut gloves. With the assistance of TRDC Company, NASA successfully applied textile materials containing microcapsules of phase change materials (MPCM) to spacesuits.

      PCM其核心物质相变微胶囊是利用微胶囊包覆技术将相变材料（芯材）封装在微小的胶囊颗粒中，避免了相变材料受外界环境的影响，当这些材料从固态变为液态或反之时，它们能在温度几乎不变的情况下，吸收或释放热量，从而达到自主调温的效果。

The core material of PCM, phase change microcapsules, is obtained by encapsulating phase change materials (core materials) in tiny capsule particles through microcapsule coating technology. This prevents the phase change materials from being affected by the external environment. When these materials change from solid to liquid or vice versa, they can absorb or release heat at almost constant temperatures, thereby achieving the effect of self-regulating temperature.

This lightweight air phase change temperature regulating fiber not only provides a cool sensation in summer but also stores heat for warmth in winter.

02相变调温纤维工作原理

Working principle of phase change temperature regulating fiber

吸热过程 Endothermic process：

      当环境温度升高时，相变材料开始从固态转变为液态。在这个过程中，相变材料吸收周围环境热量，将其储存形成潜热。例如，在炎热的夏季，人体会产生大量热量，轻空相变调温纤维中的相变材料吸收这些热量，从而降低人体周围的温度，使人感觉凉爽，这个吸热过程可以有效地缓解高温对人体的影响，提高人体舒适度。

When the ambient temperature rises, the phase change material begins to transition from a solid state to a liquid state. During this process, the phase change material absorbs heat from the surrounding environment and stores it as latent heat. For example, in the hot summer, the human body generates a large amount of heat. The phase change material in the lightAIR phase change temperature-regulating fiber absorbs this heat, thereby reducing the temperature around the human body and making people feel cool. This heat absorption process can effectively alleviate the impact of high temperatures on the human body and improve human comfort.

放热过程 Exothermic process：

      当环境温度降低时，相变材料开始从液态转变为固态。在这个过程中，相变材料释放出之前的潜热，向周围环境释放热量。例如，在寒冷的冬季，轻空相变调温纤维中的相变材料释放热量，为人体提供人外的温暖，保持人体的体温稳定。这个放热过程可以在一定程度上抵御寒冷，减少人体热量的散失。

When the ambient temperature decreases, the phase change material begins to transition from a liquid state to a solid state. During this process, the phase change material releases the latent heat it previously stored, releasing heat to the surrounding environment. For example, in the cold winter, the phase change material in the lightAIR phase change temperature-regulating fiber releases heat, providing external warmth to the human body and maintaining stable body temperature. This heat release process can resist the cold to a certain extent and reduce the loss of body heat.

      轻空相变调温纤维，利用独特相变材料的相态转变特性，在温度变化时吸收或释放热量，实现对温度的双向智能调节，为人们在复杂多变的温度环境中提供了优秀的舒适体感。

 LightAIR phase change temperature-regulating fiber utilizes the unique phase transition characteristics of phase change materials to absorb or release heat during temperature changes, achieving bidirectional intelligent temperature regulation and providing excellent comfort for people in complex and variable temperature environments.

02家纺领域：营造优质睡眠环境

Home textile field: Creating a high-quality sleep environment

      在家纺领域，轻空相变调温纤维同样发挥着重要作用。应用于床单、被罩和枕套等床上用品时，它能根据人体睡眠时的体温变化进行精准调节。当人入睡后，身体代谢产生热量，体温逐渐升高，此时相变材料会吸收多余的热量，使人感觉凉爽舒适；而当后半夜体温有所下降时，相变材料又会释放出热量，保持温暖，有助于提高睡眠质量，让人们拥有一个安稳的夜晚。

In the field of home textiles, lightweight phase change temperature-regulating fibers also play a significant role. When applied to bedding items such as bedsheets, quilt covers, and pillowcases, they can precisely adjust according to the body temperature changes during sleep. After a person falls asleep, the body generates heat through metabolism, causing the body temperature to gradually rise. At this time, the phase change material absorbs excess heat, making people feel cool and comfortable. However, when the body temperature drops in the latter part of the night, the phase change material releases heat to maintain warmth, which helps improve sleep quality and ensures a peaceful night's sleep.

      在寒冷的冬天，相变调温毛毯更是成为人们的贴心伴侣。它可以在人体接触时吸收多余的热量，避免过热带来的不适；当人体离开后，又能缓慢释放热量，保持毛毯的温度，再次使用时不会感到寒冷，为人们提供持续的温暖。

 In the cold winter, phase change temperature regulating blankets become an intimate companion for people. They can absorb excess heat when in contact with the human body, avoiding discomfort caused by overheating; when the human body leaves, they can slowly release heat to maintain the temperature of the blanket, so that it won't feel cold when used again, providing continuous warmth for people.

03医疗保健领域：助力康复与护理

Healthcare: Assisting in rehabilitation and nursing

      在医疗保健领域，轻空相变调温纤维为患者和医护人员带来了诸多便利。在康复护理方面，一些患者对温度较为敏感，使用轻空相变调温纤维制作的护膝、护腰等康复用品，可以根据患者身体局部的温度变化进行智能调节。当局部温度过高时，吸收热量；温度过低时，释放热量，促进血液循环，缓解疼痛，有助于患者的康复。

In the field of healthcare, lightweight air phase change temperature regulating fibers have brought numerous conveniences to both patients and medical staff. In terms of rehabilitation care, some patients are sensitive to temperature. Rehabilitation products such as knee pads and waist supports made from lightweight air phase change temperature regulating fibers can intelligently adjust according to local temperature changes in the patient's body. When the local temperature is too high, they absorb heat; when it is too low, they release heat, promoting blood circulation, alleviating pain, and facilitating the patient's recovery.

      在医院的手术室和病房，对于一些对温度要求较高的患者，如新生儿、老年人等，轻空相变调温纤维制成的医疗服装能为他们提供稳定适宜的温度环境，保护他们的身体健康，辅助医疗护理工作的顺利开展。

04航空航天领域：保障宇航员生命安全

Aerospace field: ensuring the safety of astronauts

      在航空航天领域，轻空相变调温纤维发挥着不可替代的作用。太空环境极其恶劣，温度变化极为剧烈。当航天器处于太阳直射区域时，温度可高达100多摄氏度；而进入背阳面时，温度又会骤降至零下100多摄氏度。

In the aerospace field, lightweight phase change temperature regulation fibers play an irreplaceable role. The space environment is extremely harsh, with drastic temperature changes. When a spacecraft is in the direct sunlight area, the temperature can reach over 100 degrees Celsius; however, when it enters the shaded area, the temperature can plummet to over minus 100 degrees Celsius.

      宇航员所穿着的航天服中使用相变调温纤维，能有效应对这种极端的温度变化。当航天服外温度升高到相变材料的熔点时，相变材料从固态转变为液态，吸收大量热量，防止宇航员因高温而中暑或身体机能受损。而当温度降低到相变材料的凝固点时，相变材料从液态转变为固态，释放出之前储存的热量，为宇航员保持体温，避免在寒冷环境中失温，保障宇航员在太空中的生命安全和正常工作。此外，在航天器的内部装饰材料中应用相变调温纤维，还可以调节舱内的温度，为宇航员创造一个相对稳定、舒适的工作和生活环境。

The space suits worn by astronauts incorporate phase change temperature-regulating fibers, which effectively cope with such extreme temperature variations. When the temperature outside the space suit rises to the melting point of the phase change material, the material transitions from a solid to a liquid state, absorbing a large amount of heat and preventing astronauts from suffering heatstroke or impaired bodily functions due to high temperatures. Conversely, when the temperature drops to the freezing point of the phase change material, the material transitions from a liquid to a solid state, releasing the heat it has previously stored, thereby maintaining the astronauts' body temperature and preventing hypothermia in cold environments, ensuring their safety and normal functioning in space. Furthermore, the application of phase change temperature-regulating fibers in the interior decoration materials of spacecraft can also regulate the temperature inside the cabin, creating a relatively stable and comfortable working and living environment for astronauts.
