Abstract

The effect of chemical treatment on strength of dyed cotton fibres using a simple light microscope and "Dumbell" test was studied. The results indicated that the drop in strength of treated cotton fibres(scoured, bleached, and dyed with seven different dyes) was accompanied by a drop in quality numbers, or/and with the increase in he number of damaged fibres. For dyed cotton fibre, the maximum drop in quality number was higher with Drimarene dyes than that with Direct dyes.
