Unverified防晒效果依赖织物密度与后整理涂层，深色（黑/藏青）比浅色UPF更高，浅色面罩需确认UPF实测值而非仅看颜色91% similarUnverified防晒UPF值和透气性权衡：UPF值靠高密度织物或涂层实现，高密度更闷热，涂层型多次水洗后防晒衰减，长期用选原纱防晒(面料本身抗紫外)89% 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88% similarUnverified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87% similarUnverified冰丝/凉感面料的防晒依赖涂层或密度，多次洗涤后UPF会衰减；标注'织物结构本身防晒（高密度锦纶+氨纶）'的产品耐洗性优于'涂层防晒'，认准非涂层工艺87% similar
