DWR is unfortunately not permanent! Under usual wearing conditions the repellency rate will be 80% still after 20 household washes. However, tearing and pyhsical abrasion on the arms or caused by equipment like backpacks or belts, plus exposure to dirt, detergents, insect repellent, and other impurities is shorten this period.
In addition, once the water repellency is going down, the yarns of your outershell will be saturated more and more by water and leaving you feeling damp and clammy like a leaking garment although no water is coming really through.
But the repellency can be recovered and we recommend the following options:
1. Iron the dry garment on gentle setting (warm, no steam) by placing a towel or cloth between the garment and the iron. This will help reactivate the DWR treatment on your garment’s outer fabric.
2. once the DWR by ironing can no longer be reactivated, apply a new water-repellent treatment (either as wash-in product or as a pump-spray).
- please follow the suggestions made by the garment brand as well as from the wash-in manuals for the right type of product
- fabrics treated with our BD finish (C-0 typem of DWR) should be also reimpregneted with fluorocarbon free products.
