Printing dyes or Hot dyes. These Reactive Dyestuffs are used for Printing on Cellulose textiles.
Reactive Printing dyes react with cellulosic fibre in the presence of alkali and under the influence of heat.
Conventional thickening such as starch, guar gum etc. are not recommended because they react with the dye and produce prints of harsh feel, lower fastness and staining of the ground fabric. Sodium Alginate alone or in combination with an emulsion is highly recommended. An addition of sequestering agent (for example Sodium Hexametaphosphate) is recommended to improve the flow properties of the print-paste.
It is prepared by slow addition of 40 parts of sodium alginate (Manutex Rs) to 960 parts of cold water under high speed stirrer till homogeneous paste is obtained.
