摘　　要：对轻薄型聚氨酯涂层面料只采用有机溶剂进行溶解剥离,效果不太理想。通过试验发现,采用氢氧化钠溶液先对样品进行碱处理,四氢呋喃、二甲基甲酰胺对轻薄型PU涂层的剥离效果大为改善,丙酮、乙酸乙酯对基布与涂层也能实现分离。分离后基布能满足定量分析的要求,碱处理后溶剂选择范围也得到扩大,对不同基布纤维成分的试样有很好的适用性。For some light PU coated fabrics,only organic solvent is used to dissolve and peel,so the effect is not ideal.It is found that the stripping effect of tetrahydrofuran and dimethylformamide on the light PU coating is greatly improved by alkali treatment with sodium hydroxide solution,and acetone and ethyl acetate could also separate the substrate from the coating.After separation,the substrate could meet the requirements of quantitative analysis,and the range of solvent selection after alkali treatment is also expanded,which has a good applicability for samples with different substrate fiber composition.
