In the textile industry, our sodium silicate and metasilicate are used for cleaning, scouring, bleaching and dye fixing operations. Dye fixation: Our sodium silicate is used as an alkaline buffer to maintain the stability of reactive dyes. Bleaching agent stability: peroxide, used for bleaching, degraded under the catalysis of copper, iron, manganese and other metals. Adding our water glass will deactivate these metals and prevent premature degradation of active oxygen. Cleaning: Our sodium metasilicate is particularly suitable for removing light or heavy grease and soil.
