Influence of Fractal Structure on Light Absorption of down Fiber Assembly

Abstract:

Ultraviolet and visible light absorption property of fiber assembly is considered to be determined by the material structure. In this paper, X-ray computed tomography was implemented to characterize the internal porous structures of down fiber assemblies. And then fractal methods were used to clarify the nonlinear structures. Ultraviolet and visible spectrophotometer was adopted to measure the UV and visible light absorbance of down fibers. The peak of absorption curve appeared red or blue shift according to the different fractal dimensions. The relationship between the absorption peak and fractal dimensions was built up.
