摘要
Device for controlling the rate of pigment depletion in a dyeing liquor includes a density measuring instrument connected to the dyeing vat and the measurement of rate of variation of density is used to control rate of pigment depletion. Device is more accurate than the colour sensitive photo-electric means of prior art.
