A radiative cooling garment is proposed as a promising strategy for ordinary people to attain high thermal comfort indoors and outdoors. However, low production and poor cooling capability restrict its wide applications. Herein, a high‐performance fiber and its textile with pore and wrinkle structures are fabricated that consist of polyethylene (PE) and polyethylene oxide. This specific structure endows the fiber and textile with high IR absorbance/emissivity (90.97%) and sunlight reflectance (93.77%). Therefore, the hybrid porous PE fiber and textile show good cooling capabilities and avoid the human body overheating by 6.8 °C under direct solar irradiation. The inner temperature of the transparent house with a roof covered by the textile decreases by 20.3 and 12.5 °C compared to the states of no extra cover and cotton cover, respectively. Apart from that, the results of the simulating and real human body measurements demonstrate that the porous PE textile enables the human body to acquire the same thermal comfort as the bare state. More importantly, the porous PE fiber and textile are superlight, flexible, moisture‐permeable, and waterproof, and meanwhile, have excellent tensile strength and UV protection properties. The good comprehensive performance indicates that the textile is appealing for fabricating summer clothes.

可扩展混合纤维及其具有孔和皱纹结构的纺织品，用于被动式个人冷却

辐射散热服被建议为普通百姓在室内和室外获得高热舒适性的有前途的策略。但是，低产量和差的冷却能力限制了其广泛的应用。在此，制造了一种由聚乙烯（PE）和聚环氧乙烷组成的高性能纤维及其具有毛孔和皱纹结构的纺织品。这种特殊的结构使纤维和纺织品具有很高的红外吸收率/发射率（90.97％）和日光反射率（93.77％）。因此，混合的多孔PE纤维和纺织品显示出良好的冷却能力，并避免了在直接日光照射下人体过热6.8°C的情况。与没有额外覆盖物和棉花覆盖物的状态相比，带有被纺织品覆盖的屋顶的透明房屋的内部温度分别降低了20.3和12.5°C。除此之外，模拟和真实人体测量的结果表明，多孔PE织物使人体获得与裸露状态相同的热舒适性。更重要的是，多孔聚乙烯纤维和纺织品具有超轻，柔韧性，透湿性和防水性，同时具有出色的拉伸强度和紫外线防护性能。良好的综合性能表明该纺织品对制造夏季服装很有吸引力。具有出色的拉伸强度和紫外线防护性能。良好的综合性能表明该纺织品对制造夏季服装很有吸引力。具有出色的拉伸强度和紫外线防护性能。良好的综合性能表明该纺织品对制造夏季服装很有吸引力。
