Wool fibre and fabric have been treated with liquid ammonia and their surface characteristics investigated by means of scanning electron microscopy and electron spectroscopy for chemical analysis. The treated specimens were dyed with levelling and milling acid dyes. although no changes in nitrogen content and fibre surface properties were detected, the dyeing rate was increased considerably as was saturation dye exhaustion. Dyeing properties were similar to those of wool treated with low-temperature plasmas by glow discharge. Fabrics treated with liquid ammonia were dyed at various temperatures in the range 30-80℃, and dye uptake was similarly increased.
