Unverified遮阳篷面料的防晒性能主要来自紧密织造与涂层，纯棉/纱布类面料透气好但UPF往往不足，涤纶加涂层款UPF更高，机洗后涂层会逐渐衰减需注意保养85% similarUnverifiedUPF防晒性能与透气性存在矛盾：致密涂层/高密织物防晒强但闷热，蜂窝网眼款透气但需依赖织物本身UPF而非涂层，选购时优先看原纱防晒而非后整理涂层（涂层水洗后易衰减）85% similarUnverified防晒和透气存在矛盾：织物越密UPF越高但越闷热，腋下/背部有激光打孔或网眼拼接的款可缓解，但拼接处防晒会打折，需权衡场景84% similarUnverified防晒效果主要取决于面料织物密度和涂层，深色比浅色UPF高1-2档；冰丝凉感面料防晒普遍偏弱，需额外确认UPF数值84% similarUnverified防晒性能主要靠面料涂层和织物密度，纯棉/亚麻等天然透气材质UPF普遍偏低（15-25），高UPF往往依赖聚酯纤维+防晒涂层，透气性与防晒力存在矛盾83% similar
