Optical properties of dyed and colored PAN nanofibers

摘要

The optical properties of fibrous materials depend on their fineness and the optical properties of the additives such ascolorant.This work investigates the optical properties of white,colored and dyed PAN nanofiber in different rangeof diameter.The morphology and diameter of nanofiber were analyzed using the Scanning Electron Microscopy(SEM).The reflectance spectra,lightness and chroma of white,colored and dyed PAN nanofiber were measured byspectrophotometer to study the optical properties of nanofiber.The obtained results indicate that the reflectance,lightness and chroma of PAN nanofiber depend on the diameter of nanofiber.The reflectance and lightness aredecreased with increasing the diameter of nanofiber.As well,the chroma is increased with increasing the diameter ofnanofiber.Also,the reflectance and lightness of nanofiber is more than micron fiber and yarn.
