A. Riva et al., SORPTION OF NONIONIC AUXILIARY PRODUCTS BY WOOL AND ITS INFLUENCE ON DYEING WITH ACID DYES, Journal of the Society of Dyers and Colourists, 112(4), 1996, pp. 114-116
Pretreatment of wool fibres with nonionic auxiliary products recommend
ed for low-temperature dyeing resulted in an increase in dyebath exhau

roduct was absorbed to a certain extent by the wool. This absorption o
ccurred rapidly and produced an increase in dyebath exhaustion and imp
roved the levelness of the resultant dyeings
