摘要
Fabric is a kind of turbid materials with strong light scattering, to which the Kubelka-Munk theory can be applied to describe it optical behavior. In this paper, the light absorption coefficients of dyestuff in fabrics are obtained by test and calculation through a special method proposed by the authors. Then the optical behaviours of dyestuff in fabric are studied. Results show that, the absorption coefficient of dye in fabric is non-scalable and exponential to dye concentration in fabric which is totally different from that of the dye in transparent media like water.
