Textile softening is an essential finishing process in the making of fabrics. In softening, the fabric is passed through an immersion bath containing a softener solution via rollers. The concentration of the bath must be monitored and kept constant in order to obtain a consistent end-product quality.
Vaisala K-PATENTS® Refractometer PR-43-GC is installed in the recycling line of the bath after the pump. The refractometer is mounted on a pipe bend, for a better flow velocity and self-cleaning effect.
