Textiles Softening Bath

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.

During the treatment, the fabric may bring some water with it (e.g. if it comes from a previous dyeing step), thus diluting the bath. In such cases, the softener needs to be replenished to bring its concentration back to the optimal level.
On the other hand, if dry fabric is treated, it will absorb some water and increase the concentration of softener.

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.
