Investigation on Physical Properties of Fluorescent Dyed Cotton Knit Fabric

摘要

This study attempted to dye the knit fabric with fluorescent dye in different shade percentages(5%,7.5% & 10% )and investigate their effects on physical properties of dyed fabrics e.g. strength, stiffness, fastness properties, k/s value, handle properties etc. Exhaust dyeing method was applied in the experiments for 100% cotton knitted fabrics. The physical properties of the dyed knitted fabrics , before and after the treatment of fluorescent dyes were determined and evaluated . Also knit dyed fabrics were compared with woven fabrics in terms of color exhaustion. This work evinces that fluorescent dye has no inauspicious effect on the physical properties of cotton knit fabric.
