Modification of cotton by acrylic acid (AA) in the presence of NaH2PO4 and K2S2O8 as catalysts under thermal treatment

摘要: Abstract Cotton fabric was modified using acrylic acid (AA) as the finishing agent in presence of K2S2O8 and NaH2PO4 catalysts separately or selected combinations, employing a pad-dry-cure technique. Treatment with 8% AA at 30°C pH 7 produced optimum effects: batching time 30–45 min followed by drying batched 95°C for 5 curing dried 140°C most balanced improvements textile related properties. catalyst allowed esterification cellulosic constituent cotton, radical polymerization free-AA cotton bound moieties, ultimately leading to some degree crosslinking chain polymers cotton.
