Sodium Silicate is used to condition fabrics and fibers by removing waxes, greases, and lanolin. It improves cleaning efficiency and prevents the reaccumulation of dirt.

Sodium silicate solution is used as a mordant in hand-dyeing processes, particularly with dyes that react in high pH environments to interact with textile fibers. It also helps reduce the degradation of bleaching agents, provides a protective coating to prevent fiber damage, and extends the colorfastness in batik work.
