Abstract
Novel oxidative desizing agent consisting essentially of from 10 to 80, preferably 50 to 80% by weight of a surfactant and from 20 to 90, preferably 20 to 50% by weight of potassium persulfate. This desizing agent may optionally also contain from 5 to 25% by weight of a solubilizer with a simultaneous reduction of the surfactant and persulfate portions.
Claims3
Oxidative desizing agent consisting essentially of, for use in an impregnation bath, a mixture of from 10 to 80% by weight of a surfactant selected from the group consisting of alkane sulfonates with from 8 to 20 carbon atoms, C.sub.8 -C.sub.20 -alkyl benzene sulfonates, C.sub.8 -C.sub.20 -olefinsulfonates, C.sub.10 -C.sub.18 -fatty alcohol sulfonates, polyethylene glycols with from 6 to 20 ethylene oxide units, C.sub.10 -C.sub.18 -fatty alcohol oxethylates with from 6 to 24 ethylene oxide units, C.sub.4 -C.sub.12 -alkylphenol oxethylates with from 6 to 20 ethylene oxide units and from 20 to 90% by weight of potassium persulfate, said mixture being prepared before use in said bath.
