What Kind of Cloth Works Best for Dew Wick?

Choosing the Right Cloth

When selecting a cloth for a dew wick, it’s essential to consider the material’s absorption rate and water retention capacity. While cotton and its blends can be effective, microfiber cloths outperform them due to their smaller fiber diameter, which creates a larger surface area for water absorption. A microfiber cloth with a density of 150-200 grams per square meter (gsm) is an ideal choice.

Measuring Absorption Rate

To determine a cloth’s absorption rate, you can perform a simple test. Cut a 5-inch by 5-inch square of the desired cloth and weigh it. Then, place the cloth in a shallow dish of water and time how long it takes to absorb 2 milliliters (mL) of water. A cloth that absorbs 2 mL in under 10 seconds is considered effective. For a dew wick, you’ll want a cloth that absorbs water quickly, but also retains its moisture to maximize water collection.

Additional Considerations

When selecting a cloth for a dew wick, also consider its durability and resistance to wind and sun exposure. A cloth that can withstand repeated use and exposure to the elements will provide more consistent water collection. You can also consider treating the cloth with a waterproofing agent to enhance its performance and extend its lifespan.
