Effect of Abrasion Process on Reflectance Factor and Color Change of ChenilleWoven Fabrics

This paper focuses on effect of abrasion process on color change and reflectance factor of dyed wovenfabrics containing 100% acrylic chenille yarns in weft and cotton warp yarns. Three fabrics having 12,14 and 16 weft per centimeter were dyed with three dyes in different hues i.e. C.I. basic yellow12, C.I.basic blue41, and C.I. basic red46. Four different abrasion levels, i.e. 50,200,400 and 650 were selectedto abrade samples. The results show that abrasion of samples leads to decrease of reflectance factor andincrease of color change up to specific levels of abrasion, although this variation was not the same fordifferent hues and weft densities. It was found that reflectance factor and color change of fabrics thathave higher weft density were more affected by abrasion at all abrasion levels. Finally analysis ofvariance and multiplr linear regression was performed at 95% confidence level. According to multiplelinear regression models weft density had the most dominant effect on reflectance factor. Moreover,number of abrasion cycle was the most significant parameter on color change of chenille wovenfabrics. The R2-value of regression model of color change, and reflectance factor, was 0.897, 0.963respectively, which confirms the good fitness of proposed models.
