摘　　要：以不同混纺比的棉纤维与聚酯纤维混纺织物作为试验对象,分别研究了不同纤维配比的单层试样和双层试样在紫外波段内的透射率变化情况。结果表明,织物阻隔紫外线属纯物理叠加效应,不同纤维成分的织物在紫外波段内的透射率曲线具有一定的特征变化,混纺织物的曲线具有一定的特征加和性,符合假设的线性加和模型。The greige fabrics with different cotton-polyester fiber ratio are selected as experimental samples,and the ultraviolet transmittance variation of single-layer and double-layer samples are studied respectively.The result shows that the process of ultraviolet transmission over fabric is a pure physical superimposed effect,the ultraviolet transmittance-wavelength curves of fabrics with different fiber ratio show certain regular changes,and cotton-polyester blended fabrics’curves have the additivity of characteristic wavelengths,which is accord with the assumption of the linear additivity model.
