PROLEN®YARN is waterproof, it doesn´t fear stains and spots. PROLEN®YARN clothes do not shrink, do not become narrower and can be washed in the washing  machine at 40 degrees Celsius with only one third of the usual detergent. Stains and spots do no subside inside the fibre, but they stay on ist surface and this enables an easier and faster cleaning. PROLEN®YARN is not electrostatic and doesn´ t attract atmospheric dust. PROLEN®YARN garments dry fast and do not need ironing. After washing you just need to hang them for a while and then you can put them on and continue in your activities.
