银胶涂层遮光布正面朝室内会反光且手感偏硬、时间久易脱层开裂；优先选黑丝纱（三织黑丝）一体成型工艺，遮光靠纱线本身而非涂层，可水洗且更耐用

Unverified遮光原理分两类：银胶/黑胶涂层布靠背面涂层遮光（涂层可能开裂脱落，怕高温），高密度提花/黑丝布靠织物本身密度遮光（更耐用、可水洗但价格高），追求长期耐用选后者91% similarUnverified银胶/黑胶涂层遮光布不可机洗且不能暴晒，涂层遇高温摩擦会脱落龟裂；追求可机洗应选原纱染色的高密度提花遮光布（三防面料）91% similarUnverified涂层遮光布（银胶/黑丝涂层）遮光率高但不透气、易折痕开裂，且部分银胶涂层不可机洗；提花/多层织物遮光布更耐用透气，适合长期使用和潮湿地区91% similarUnverified银胶/黑丝涂层遮光布遮光率高但透气差、易在潮湿环境发霉且不耐水洗，三层编织（黑纱夹层）遮光布可机洗更适合长期使用91% similarUnverified黑丝布（三层黑纱）遮光率高但透气差易发闷，涂层银胶布遮光同样好但易开裂脱落，长期使用优先选夹层黑丝而非表面涂层工艺89% similar
