Comparison of color values of plain cotton fabrics knitted from ring- and compact-spun yarns

Abstract

The color values of dyed, plain-knitted, cotton fabrics, made from ring- and compact-spun yarns of different yarn counts and having the same constructional properties, were compared. Color values (lightness (L*), chroma (C*), color strength (K/S), and color difference (Delta E*)) changed with yarn count and type, and differed for undyed and dyed fabrics. As the yarn count increased, the C* and K/S values increased, but the L* values decreased for dyed fabrics, as opposed to undyed fabrics. The hairiness decreased with increased yarn count. The yarn hairiness, type, and count, together with the bulky structure of knitted fabrics, played a very important role in light reflectance. Fabrics knitted from ring-spun yarns appear darker and more saturated in color.
