The short care programme: Washing and caring for membrane clothing correctly

How often membrane clothing needs to be washed depends on how often we wear the garment and how dirty it is - and also on the type of membrane. Before putting functional textiles in the washing machine, you should take a look at the care label, as not every laminate can cope with everything.

How often should a rain jacket be washed?

Manufacturers of microporous membranes (e.g. Gore-Tex, E-Vent etc.) point out that sweat, salt crystals, dirt and skin oils can impair the breathability and durability of bonded seams and the membrane. They therefore recommend regular washing of clothing. The manufacturers of non-porous membranes (e.g. Sympatex, Dermizax) emphasise that their membranes cannot become clogged and therefore retain their function regardless of how often they are washed.

Washing and caring for functional clothing correctly

• Fully close all zips, cover strips, Velcro fasteners and straps before washing.
• Follow the instructions on the care label.
• Washing machine: low load, set gentle cycle at 30 degrees (some modern washing machines have a special programme for outdoor textiles).
• Use as little liquid mild detergent as possible or special detergents for functional clothing. The amount depends on the soiling and the water hardness.
• Do not use heavy-duty detergent with brighteners or bleach! Fabric softener is also taboo as it damages the impregnation!
• Do not spin (or only at very low speed).
• Some manufacturers recommend tumble drying as this reactivates the impregnation. Low temperatures and short drying times (approx. 20 minutes) are important.
• Ironing also reactivates the impregnation. However, the ironing temperature should not exceed 110 degrees (1 point/level 1). To be on the safe side, place a thin cotton cloth (e.g. a tea towel) between the functional fabric and the iron.
• Dry cleaning is possible for some textiles, but not necessary.
