Investigation Into the Color Variation of Textile Materials Using Digital Imaging Devices Sohail Shahamatjoo s shahamatjoo@tx iut ac ir September Department of Textile Engineering Isfahan University of Technology Isfahan Iran Degree M Sc Language Persian Dr H Khalili khalili@cc iut ac ir Dr H Izadan izadan@cc iut ac ir Abstract Development of the techniques to improve the appearance of fabrics has long been important for the researchers in textile and its related industries Thus techniques are usually done in subjective and objective methods The subjective methods are conducted by visual assessment which is observer dependent and usually does not have an acceptable repeatability The objective methods are often difficult to calculate however due to the important benefits of them many researches have been conducted using these methods such as analysis of spectral data the application of digital devices and image processing techniques One of the important appearance properties of fabrics is color levelness In the present research the objective method of color levelness assessment are used and compared with the visual assessment of the color levelness of fabric To do this panels which have been prepared in a previous research by Ms Doustkami are used It is claimed that these panels cover reasonable proportion of color space These panels then judged by observers males females in order to assess the color levelness of them Using a steps Likert scale and a categorical judgment technique the visual data were converted to an interval scale data Also the reflectance of the panels was measured in different random locations of them with two different small and large spectrophotometer measuring apertures After converting the spectral data into L a b under D illuminant and degree standard observer the average DE and CMC color difference between the L a b of the locations of each of the panels and the average L a b of all the locations were calculated and considered as a measure of color levelness of the panels This measure then is compared with some important measured used in previous researches PDF created with pdfFactory trial version www pdffactory com
