Equipment companies apply a water repellent durable finish, or DWR, all sorts of things today: jackets, of course, but also sleeping bags, pants, even hats. This is what makes the water drip and roll. Because many traditional raincoats have facial tissues, DWR is important to ensure that it is not clogged and stifles the breathability of the underlying waterproof membrane. When DWR layer does not work, the outer tissue absorbs water (which is called "wetting"), which carries weight and loses the ability to breathe the key.
The good news is that the DWR treatment is just a coating and can be easily revived. Next, we'll show you how to make the most of it and apply a new finish.
# 1. Wash first (and often)
"Most of the time, when someone says, 'My jacket is not waterproof, just wash it,' says Lindsey Stein, marketing manager of Rainy Pass , one of the largest hardware repair states states. out in the country. The dirt, body oil, sunscreen and especially the smoke of the fire worsen the DWR, allowing water to penetrate the tissue. Wash impurities can return. "Many people think that cleans one of the DWR jacket eliminates," adds Heidi Allen, vice president of marketing Nikwax . " That's not true, it's better to wash. "Who do not use it every time he uses it instead means using it as a good pair of jeans and washing your jacket when you start to wash their jackets stone at least once a season and after long trips and more often for aerobics jackets, if you sweat a lot in it.
# 2. Use a technical washcloth
Household cleaners can leave residues that act as oil and dirt and can attract water. In contrast, Gear Aid and Nikwax have biodegradable soaps that are softer on textiles and the environment than detergents.
# 3. Try the DWR
Dry the jacket according to the care label and test the DWR by spraying or spraying water on the shoulders, waist and back. If the water will bead and roll, your jacket is good for another ride. If water on the jacket is filtered or the fabric color changes, the DWR must be reapplied. You can also say that when you wear your own jacket in the rain. If the rain does not overlap or the fabric feels damp, it is time to reapply.
# 4. Choose your application method
DWR cleaners come in the form of aerosols and sprays or a rinse treatment. Since aerosols tend to use environmentally harmful chemicals, we do not recommend them. The washing works like washing soap and soaking the garment in the DWR treatment. It's the best for shell jackets. "It eliminates user errors," says Allen. "They will not lose any space and the washings will have no impact on breathability." The liquid spray is applied with a bottle of water outside the jacket. It works best with insulated and multi-layered jackets and sleeping bags, where the insulation absorbs much of the laundry.
spraying
After washing (drying is optional), hang your jacket and spray everywhere, including the hood and underarms. Give the shoulders, chest, and waist a few extra shots where most of the abrasion occurs and the water repellent wears off faster. Wipe off additional liquid.
laundry application
Read the DWR label to see how much you need to add for the amount of laundry and your washing machine type. Most bottles can apply two or three jackets at once. Insert the DWR and clothing into a washing machine cycle as instructed, usually a hot water wash and a slow turn.
# 5. Read the label before drying
Some types of waterproof and breathable membranes should never get into the dryer, while some DWRs are better revitalized with heat: read the label for drying instructions. If the garment gets into the dryer, Stone recommends the lowest heat setting for only 15 to 20 minutes.
