| Abstract: | Scoured and bleached ramie fabrics were pretreated separately with four swe1lidg agents, viz. NaOH, EDTA, urea and phosphoric acid, and the consequent changes in tensile properties, extent of decrystallization, absorbency, dye uptake and fastness to washing light and rubbing for a monochlorotriazine reactive dye (C.I. Reactive Orange 13) were evaluated. Pretreatment with 20% urea or 20% NaOH under slack condition resulted in a more desirable balance in the above-mentioned properties including the improved dye uptake. Fastness to rubbing was poor and it was more pronounced at higher number of rub cycles. Both ring dyeing and higher coefficient of friction of ramie have been found to be responsible for this. To improve the rub fastness of reactive-dyed ramie fabric, post-treatment was carried out separately with catasoftener, silicone and polyethylene emulsion. Post-treatment with the last two finishing agents improved the rub fastness significantly on both NaOH (slack) and urea (slack) pretreated and reactive-dyed ramie fabrics. |
