A Comparative Study on the Dyeability of Stabraq (Milkweed) Fibers with ‎Reactive Dyes

I n this work, raw fibers of a local ‎species of stabraq (milkweed) were ‎scoured, bleached and blended ‎with cotton fibers with a ratio of ‎‎75/25 (cotton/stabraq). The ‎improved stabraq fibers, scoured ‎and bleached cotton and the ‎blended fibers were spun into fine ‎yarns and then they were subjected ‎to dyeing with two types of reactive ‎dyes namely, cold brand and high ‎exhaustion brand reactive dye at ‎‎1% omf in a liquor ratio of 20:1, in ‎the exhaustion dyeing method. The ‎extent of exhaustion, colour ‎strength and other colorimetric ‎parameters of the dyeing were ‎determined and the results were ‎compared. The results suggested ‎that the dyeability of stabraq fibers ‎with two reactive dyes used, ‎resembles that of cotton yarns ‎more closely, and the blended ‎fibers exhibited superior dyeing ‎behavior than the alone fibers.‎
