Unverified82% confidenceCautionTime unknown
防泼水（DWR涂层）不等于防水，洗涤后逐渐失效，一般30-50次洗涤后需重新喷涂免洗防泼水剂恢复；把DWR当防水裤买用于雨天会失望

Unverified作为入门级雨裤，防水涂层（DWR）经多次穿用洗涤后会逐渐失效，使用前建议确认是否需要单独购买防水喷雾进行补涂维护，否则长期使用防水性能会明显下降。93% similarUnverified防泼水依赖DWR涂层，实测水珠成球滚落即达标，但DWR会随洗涤磨损失效，约20-30次洗涤后需重新喷涂防水剂养护92% similarUnverified防泼水（DWR涂层）与真正防水是两回事：DWR只能应对小雨和短时暴露，涂层会随洗涤衰减（约20次水洗后失效），需靠熨烫或重新喷涂恢复；长期淋雨需求应选压胶防水面料92% similarUnverified防泼水涂层（DWR）经多次洗涤后防水效果会明显衰减，非真正防水面料，不适合在持续中雨或大雨中使用。92% similarUnverified防水裤的防水失效多来自DWR（耐久拒水涂层）衰减而非防水膜损坏，出现表面'湿透吸水'现象时可用洗涤后低温烘干或补喷DWR恢复，而非直接更换92% similar
