Cotton fabric was modified using methacrylic acid (MAA) as the finishing agent in the presence of NaH2PO4 and K2S2O8 catalysts separately or in selected combinations, employing a pad-dry-cure technique. Treatment with 8% MAA at 30°C and at pH 6 produced optimum effects: a batching time of 45-60 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 produced most balanced improvements in the properties such as wrinkle recovery, abrasion resistance, extensibility and moisture regain with retention of more than 75% of the original strength. NaH2PO4 catalyst allowed esterification of MAA with the cellulosic constituent of the cotton, and K2S2O8 catalyst allowed radical polymerization of free MAA or cotton-bound MAA moieties; the said process ultimately led to some degree of cross-linking of the chain polymers of cotton. |
