Textile Check for Spin Finish Removal

For certain applications, it is important that the textiles are free of Spin Finish. Especially for bulletproof vests, Spin Finish has to be washed off completely. If Spin Finish is not fully removed, the bullet would slide through the vest despite the set-up of several overlaid textile layers. For other applications, Spin Finish has to be removed, too: for example, prior to surface functionalization for windproof or water repellent property. The minispec is able to detect Spin Finish down to very low concentrations. Thus, it is the method of choice to monitor the washing of Spin Finish on fibers and control the absence of Spin Finish.
