Abstract
Oxidative desizing agent consisting substantially of from 5 to 20 weight % of sodium or ammonium persulfate or potassium, sodium, ammonium or calcium peroxodiphosphate, from 20 to 50 weight % of one or more surfactants selected from the group of C.sub.8 -C.sub.20 -sec.-alkanesulfonates, C.sub.4 -C.sub.12 -alkylphenol-oxethylates having 6 to 12 ethylene oxide moieties, or C.sub.10 -C.sub.18 -fatty alcohol-oxethylates having 3 to 8 ethylene oxide moieties, and water in the amount remaining to give 100%. The advantage of this desizing agent resides in the fact that a substantially smaller amount of persulfate is required than for desizing with persulfate alone. Moreover, this desizing agent is liquid and thus easy to be dosed.
