在全球高温经济崛起与双碳战略深化的背景下，山东稀有科技发展有限公司（稀有高科）推出新品：冰晶®辐射制冷纤维/纱线，以颠覆性技术突破，重构制冷纺织品行业格局。依托独特光子调控结构，这款创新材料无需任何额外能耗，即可实现“太阳光反射+中红外辐射散热”双效制冷，实测降温幅度达 3-8℃，完美解决传统制冷材料坚硬、不可纺织的核心痛点，兼具传统纤维的轻薄质感、柔性特质与可纺织性能，为多领域提供零碳降温解决方案。
Against the backdrop of the booming global heat‑driven economy and further advancement of the dual‑carbon strategy, Shandong Rare Technology Development Co., Ltd. (Rare Hi‑Tech) unveils its new product: IceCrystal® radiative‑cooling fiber/yarn. With disruptive technological breakthroughs, it reshapes the landscape of the cooling textile industry.
Relying on its unique photon‑modulated structure, this innovative material delivers dual‑effect cooling via solar light reflection and mid‑infrared radiative heat dissipation without any extra energy consumption. It achieves a measured cooling effect of 3‑8℃. Perfectly addressing the core pain points of conventional cooling materials such as stiffness and poor spinnability, it inherits the lightweight texture, flexibility and textile processability of traditional fibers, and provides zero‑carbon cooling solutions for multiple industries.
核心技术：光子调控 + 仿生设计，解锁辐射制冷密码
冰晶（IceCrystal）的制冷原理源于对自然智慧与前沿科技的深度融合。其独特的光子调控结构灵感源自撒哈拉沙漠银蚁的纳米毛发，通过精密的微观结构设计，可反射 90% 以上的太阳辐射能，同时高效透过大气窗口释放中红外波段热量，实现 “被动辐射制冷” 的绿色降温模式。这种技术突破了传统凉感面料依赖表面涂层的局限，制冷功效源于纤维本身，经 50 次水洗后凉感保留率仍≥80%，远超行业平均水平。
与传统制冷材料相比，冰晶®纤维在保持硬核降温性能的同时，彻底打破“制冷必耗能”“降温不舒适”的行业困局，其柔软度、透气性与纺织适配性可媲美天然纤维，可无缝融入各类纺织加工工艺。
The cooling mechanism of IceCrystal stems from the in‑depth integration of natural wisdom and cutting‑edge technology. Inspired by the nanoscale hairs of Saharan silver ants, its unique photon‑modulated structure is precisely engineered at the micro level. It reflects over 90% of solar radiant energy while efficiently dissipating heat in the mid‑infrared band through atmospheric windows, realizing the eco‑friendly cooling mode of passive radiative cooling.
Breaking the limitations of conventional cool‑touch fabrics that rely on surface coatings, its cooling capability originates from the fiber itself. After 50 washing cycles, the cool‑feeling retention rate remains ≥80%, far exceeding the industry average.
Compared with traditional cooling materials, IceCrystal® fiber delivers robust cooling performance while resolving long‑standing industry dilemmas: “cooling must consume energy” and “cooling equals poor comfort”. Boasting softness, breathability and textile compatibility comparable to natural fibers, it can be seamlessly adapted to various textile processing procedures.
