Abstract

This paper focuses on the assessment of color strength and chroma values that occur in dyed polyester fabrics after different cycles of abrasion for different fabric construction parameters. We used 12 polyester fabrics with various construction parameters in two experimental sets. The fabrics differed from each other by their cover factors. The warp yarn type and count, warp density, warp yarn twist and the fabric weave were the same for all of the fabrics in each experimental set. The dyeing of the fabric samples was performed by using a commercial disperse dye (CI Disperse Red 74:1). Four different abrasion cycles (2500, 5000, 7500, 10,000) were used. The main differences in color strength and chroma values were observed between 0 and 2500 cycles of abrasion. Increasing abrasion cycles after 2500 changed the appearance of the fabrics woven from staple weft yarns considerably. It is concluded that the rubbing motion of the Martindale instrument is related to the cover factor of the fabrics and dyeing concentration applied. The main effect of abrasion on color strength and chroma values was obtained up to 2500 cycles.
