    摘要: Vinylsulfonyl dyes, if padded from acidic liquors, produce on wool merely dyeings having a poor yield and only moderate fastness properties if the pad-beam method is used. It has been found according to the invention that padding from weakly alkaline liquor (pH 7-9) with sodium bicarbonate as fixing alkali and subsequent batching (6-24 hours) of the material produces good coloristic results especially on wools with a low-felting or non-felting finish.
