Phase Change Temperature-Regulating Fiber, Phase Change Yarn, Air-Conditioning Fiber, Constant Temperature Yarn, L-PCM Lightweight Hollow Fiber

Phase Change Materials (PCMs) are materials capable of changing phase (solid, liquid, gas) at specific temperatures while providing latent heat. The process of phase transition is called the phase change process, during which the PCM absorbs or releases a large amount of latent heat, thereby enabling cold or heat storage functionality.

PCM was first used in NASA's lunar mission, developed as a new material for astronaut clothing systems to provide comfort and balance body temperature. It automatically regulates temperature to cope with the extreme heat, cold, and drastic temperature changes in space. This technology began in 1987 when NASA's Johnson Space Center collaborated with private companies to develop PCMs for extravehicular spacesuits, especially astronaut gloves. With the assistance of TRDC, NASA successfully applied textile materials containing microencapsulated phase change materials (mPCMs) to spacesuits. The core component of PCM, microencapsulated phase change materials, uses microencapsulation technology to encapsulate the phase change material (core material) within tiny capsule particles, protecting it from external environmental influences. When these materials transition from solid to liquid or vice versa, they absorb or release heat with almost no change in temperature, achieving an automatic temperature regulation effect.

Lingkong Phase Change Temperature-Regulating Fiber

01What is Phase Change Temperature-Regulating Fiber?

Lingkong Phase Change Temperature-Regulating Fiber is a temperature-smart management fiber developed by Shandong Rare Technology Development Co., Ltd. using aerospace-grade phase change materials and fiber substrates through unique nano-confinement encapsulation and polymerization technology. It combines intelligent temperature control with bidirectional temperature regulation, effectively preventing "cold-heat" stress responses and meeting comfort needs. Lingkong Phase Change Temperature-Regulating Fiber not only provides cooling in summer but also offers heat storage and warmth in winter.

02How Phase Change Temperature-Regulating Fiber Works

Heat Absorption Process:

When the ambient temperature rises, the phase change material begins to transition from solid to liquid. During this process, it absorbs heat from the surrounding environment, storing it as latent heat. For example, in hot summers, the human body generates excess heat, and the phase change material in Lingkong Phase Change Temperature-Regulating Fiber absorbs this heat, lowering the temperature around the body and providing a cooling sensation. This heat absorption process effectively mitigates the impact of high temperatures on the body, enhancing comfort.

Heat Release Process:

When the ambient temperature drops, the phase change material transitions from liquid to solid. During this process, it releases the stored latent heat, warming the surrounding environment. For example, in cold winters, the phase change material in Lingkong Phase Change Temperature-Regulating Fiber releases heat, providing additional warmth to the body and maintaining stable body temperature. This heat release process helps combat cold temperatures and reduces heat loss from the body.

Lingkong Phase Change Temperature-Regulating Fiber utilizes the unique phase transition properties of phase change materials to absorb or release heat during temperature changes, enabling bidirectional intelligent temperature regulation and providing excellent comfort in complex and variable temperature environments.

Wide Range of Applications

01Apparel: Creating Comfortable Wearable Experiences

In daily wear, Lingkong Phase Change Temperature-Regulating Fiber敏锐感知外界环境温度的变化. When summer heat arrives and external temperatures rise, the phase change material in the fiber quickly absorbs excess heat generated by the body, acting like an invisible mini air conditioner to keep people cool and comfortable. In cold winters, the phase change material releases stored heat, functioning like a贴心的小暖炉 to ward off the cold and reduce the need for频繁增减衣物.

For outdoor enthusiasts engaging in activities like hiking and trekking, where environmental temperatures vary widely,运动服装 made with Lingkong Phase Change Temperature-Regulating Fiber quickly adapts to these changes. Whether ascending from cold foothills to hot mountain peaks, it regulates body temperature in real-time, keeping the wearer comfortable and stable while reducing fatigue and injury risks due to temperature discomfort.

For specialized occupational clothing, Lingkong Phase Change Temperature-Regulating Fiber also offers benefits. For example, firefighters facing extreme heat from blazing fires can have protective gear embedded with this fiber to absorb大量热量, lower surface temperatures, and significantly reduce the risk of heatstroke and burns. Polar researchers in extremely cold environments benefit from clothing containing this fiber, which provides continuous warmth to ensure smooth operations.

In home textiles, Lingkong Phase Change Temperature-Regulating Fiber plays a crucial role. Applied to bed sheets, duvet covers, and pillowcases, it precisely adjusts to body temperature changes during sleep. As the body metabolizes and generates heat after falling asleep, the phase change material absorbs excess heat, providing a cool and comfortable feel. In the latter half of the night, as body temperature drops, the material releases heat to maintain warmth, improving sleep quality and ensuring a restful night.

In cold winters, phase change temperature-regulating blankets become贴心伴侣. They absorb excess heat upon contact to prevent overheating discomfort and slowly release heat when the body moves away, maintaining blanket warmth for reuse without feeling cold, offering continuous warmth.

03Healthcare: Aiding Rehabilitation and Care

In healthcare, Lingkong Phase Change Temperature-Regulating Fiber offers numerous benefits for patients and medical staff. In rehabilitation care, patients sensitive to temperature can use products like knee and waist supports made with this fiber, which intelligently adjust to local body temperature changes—absorbing heat when too high and releasing heat when too low—promoting blood circulation, alleviating pain, and aiding recovery.

In hospital operating rooms and wards, for temperature-sensitive patients such as newborns and the elderly, medical garments made with this fiber provide a stable and suitable temperature environment, protecting their health and supporting smooth medical care operations.

In aerospace, Lingkong Phase Change Temperature-Regulating Fiber plays an irreplaceable role. The space environment is extremely harsh with drastic temperature fluctuations. When spacecraft are in sun-exposed areas, temperatures can soar above 100°C; in shaded areas, they can plummet below -100°C.

Spacesuits equipped with phase change temperature-regulating fiber effectively handle these extreme changes. When external temperatures rise to the material's melting point, it transitions from solid to liquid, absorbing大量热量 to prevent heat-related issues for astronauts. When temperatures drop to the freezing point, it solidifies, releasing stored heat to maintain body temperature and prevent hypothermia in cold environments, ensuring astronaut safety and functionality in space. Additionally, applying this fiber to spacecraft interior materials helps regulate cabin temperature, creating a stable and comfortable working and living environment for astronauts.

In automotive applications, using Lingkong Phase Change Temperature-Regulating Fiber in car seats and interiors improves in-cabin temperature comfort. In hot summers, it reduces seat surface temperatures to prevent burns; in cold winters, it provides warmth, reducing passenger discomfort from low temperatures while decreasing the load on air conditioning systems and saving energy.

In construction, adding this fiber to building insulation materials helps regulate indoor temperatures. It absorbs heat when indoor temperatures rise and releases heat when they fall, reducing the need for air conditioning and heating, lowering energy consumption, achieving energy savings and emission reductions, and enhancing indoor comfort.
