摘要
Wool yarn has been dyed with natural colourant extracted from the bark of neem (Azadirachia indica) branchlets under the optimum conditions. Neem bark colourant shows two absorption maxima at 275 and 374 nm. Dyeing of wool yarn under the optimum conditions (pH, 4.5: colourant conc.. 0.05g per gram of wool; treatment time, 60 min; and treatment temp., 97.5degreesC) shows very good light and wash fastness properties without deteriorating the quality of wool. The chemistry of wool dyeing process has also been discussed.
