| Abstract: | 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 thnmgh a special method proposed by the authors.Then the optical behaviours of dyestuff in fabric are studied.Results show that,the absorption coeffident of dye in fabric is non-scalable and exponential to dye concentrafion in fabric which is totally different from that of the dye in transparent medm like water. |
