Dyeing of Grafted Jute Fibre with Reactive Dyes and its Improved Properties

Graft copolymerization of acrylic acid onto bleached jute fibre has been studied in aqueous solution with redox initiation system KzSzOniFeSOa. The bleached and grafted jute fibres were dyed with reactive dyes viz. Reactive Red 2, Reactive Orange 14, Reactive Blue 4 and Reactive Brown 10. It has been observed that the percentage of dye exhaustion decreases with the increase of grafting percentage. The colour fastness of dyed fibre with light, acid and alkali perspiration, and washing and spotting tests, has been assessed. For all cases grafted fibre possesses better colour fastness. The tensile strength of grafted jute fibre with prolonged exposure to sunlight, to sunlight has been measured. The grafted fibre shows greater tensile strength than that of bleached fibre
