A Study of the Damage Caused to Dyed Cotton Fibres and its Effects on the Properties of Rotor- and Ring-Spun Melange Yarns
Research and development
BRAK AUTORA Full text | Abstract: A detailed study of the effect of flock dyeing of cotton fibre on the damage and different properties of rotor- and ring-spun (100% dyed, 50% dyed and 50% grey melange) yarns is reported. It was found out that flock dyeing increases fibre damage when compared with grey fibres. The higher degree of damage of the dyed cotton fibres mixed with white ones has a negative effect on the quality of the melange cotton yarn. The quality of the melange yarn depends considerably on the blending stage, as well as the spinning systems. The higher number of drawing stages when blending black and white fibres in the draw frame results in better mechanical properties, but greater hairiness for the yarn. The presence of dyed fibres in the melange leads to a considerable decrease in the mechanical properties of rotor spun yarns, but ring spun yarns do not seem to be considerably affected. |
