Unverified85% confidenceCautionTime unknown
纯棉/纯人棉材质不适合作防晒衣：棉纤维本身UPF仅5-10，湿水后紫外线透过率剧增且不速干，防晒衣应选锦纶(尼龙)或涤纶为主的合成纤维，其分子结构本身对UVA有更强阻隔

Unverified锦纶（尼龙）本身分子结构就能阻挡紫外线，即使无涂层防晒性也优于纯棉；纯棉未染色织物UPF通常仅15-20，防晒披肩不建议选纯棉材质92% similarUnverified不建议选纯棉材质防晒衣，棉纤维本身UPF值低（约UPF5-10）、吸汗后紧贴皮肤更闷，且水洗后易变形缩水，孕妇防晒衣应选锦纶/涤纶混纺88% similarUnverified涤纶(聚酯纤维)本身防晒性优于棉、麻，且吸湿快干；纯棉袖套虽亲肤但湿水后防晒力和凉感均下降，长时间户外不推荐纯棉85% similarUnverified面料防晒能力看织物密度而非厚度：深色+高密度机织涤纶/锦纶防晒优于浅色棉麻，纯棉未经处理仅UPF5-10，湿水后防护力还会下降85% similarUnverified防晒裤的防晒能力主要来自纤维本身（涤纶/锦纶天然阻挡紫外线）而非涂层，纯棉即使加涂层也难持久，选涤纶或锦纶含量高的面料才能水洗多次不失效84% similar
