摘要

Abstract The reflectance spectra and color properties of yarn when used in carpet are different from its cross-sectional direction as the pile of hand-woven carpet. This paper presents a comprehensive study of reflectance spectra and color properties of the pile in longitudinal direction and hand-woven carpet. For this purpose, the wool yarns were dyed with madder as a natural dye in various concentrations from 10% to 100% on the weight of sample. In order to study of the optical properties of the pile of hand-woven carpet, the dyed yarns were used to weave the hand-woven carpet. The obtained results showed that the yarn in longitudinal direction is lighter than the pile of hand-woven carpet, and so, the color strength of hand-woven carpet is more than the color strength of yarn. The spectrophotometric properties of samples were also studied by Principal Component Analysis (PCA). The difference between reflectance spectra of yarn in longitudinal direction and reflectance spectra of the pile of hand-woven carpet was also shown by PCA results.
