摘要

Dyeing behaviour and colour fastness characteristics of bleached, acrylamide and acrylic acid modified jute fibres dyed with reactive dyes, namely Reactive Red 120, Reactive Blue 5, Reactive Orange 14 and Reactive Brown 10 in aqueous medium were investigated. Dye absorption were greatly affected by the parameters variables, and depended on the dye and fibre characteristics. The effective dye absorption of each dye was determined. Grafting of acrylamide and acrylic acid increased the hydrophobic nature of bleached jute fibre and hence, affected the dye absorption. Grafting improved the sunlight, wash, alkali and organic acid fastness characteristics of modified dyed jute fibre. It also reduced the strength loss of the dyed fibre on exposure to sunlight in air, in which the dye particles normally enhanced photo-oxidative degradation by absorbing UV of sunlight.
