Abstract:

The colour values of plain woven cotton fabrics made from ring- and compact-spun warp and weft yarns have been compared. Ring and compact cotton yarns were spun from 100% combed cotton at different yarn counts; ring-spun yarns having slightly higher mass irregularities and much higher hairiness than the compact-spun yarns. Fabrics having the same constructional properties were woven under the controlled mill conditions and then dyed with C.I. Reactive B lack 5 dye. It is observed that the colour values change with the change in yarn counts and differ in undyed and dyed fabrics. The yarn hairiness plays a very important role in light reflectances with regard to chroma values and fabrics woven from compact yarns appear lighter in colour because of the more regular structure of the compact-spun yarns.
