It is characterized by adding catalysts of 2-15g/L of ZnSO4 and 2-10g/L of MnSO4 in the colouring solution of concentrated sulfuric acid in which chromic anhydride is added and making chemical colouring at 33-50 deg.C. ADVANTAGE-. Said method is easy to control, good in reproducibility,...

The colour yields of the dye on the wool were found to be highly dependent of the pH, optimum results being obtained at pH 4. The K/S of wool increased in the order of the dyeing using KAl (SO4)2>MnSO4>CoSO4>FeSO4>none>ZnSO4>CuSO4. Un-mordanted samples have good properties of ...
Threads or staple fibres having improved dyeability with direct acid and premetallized dyes are formed by spinning a fibre-forming composition comprising viscose in which is incorporated an N-vinyl lactam polymer into a coagulating bath containing H2SO4 and Na2SO4 with or without ZnSO4 or MgSO4...
