Abstract: Jute fabric has been modified using methacrylic acid as the finishing agent in the presence of K₂S₂O₈ and Na₄P₂O₇ catalysts separately or in selected combinations, employing a pad-batch-dry-cure technique. It is found that the treatment with 100g/L methacrylic acid at 30°C and pH 7 using batching time of 60-75 min at 30°C followed by drying of the batched fabric at 95°C for 5 min and curing of the dried fabric at 140°C for 5 min under the catalytic influence of K₂S₂O₈ and Na₄P₂O₇ produces most balanced improvement in the textile-related properties, such as wrinkle recovery angle, flexibility, abrasion resistance, elongation-at-break and resistance to photo-yellowing with retention of strength.
