Is 100% Nylon Jacket Waterproof?.
Nylon's Water Resistance: Demystifying the Durable Water Repellent Factor
Nylon, a versatile synthetic fiber, has long been a popular choice for outdoor apparel due to its lightweight, durable, and breathable nature. However, a common misconception arises regarding its water resistance. While nylon itself is not inherently waterproof, it can be rendered water-resistant through various treatment methods, including the application of a durable water repellent (DWR) coating. This article delves into the intricacies of nylon's water resistance, demystifying the role of DWR and explaining how to maintain the water repellency of your nylon garments.
Understanding Nylon's Water Absorption
In its pure form, nylon is hydrophilic, meaning it has an affinity for water. This characteristic makes nylon susceptible to moisture absorption, leading to dampness and discomfort when worn in rainy or wet conditions. To combat this issue, manufacturers employ DWR treatments to repel water from the surface of the nylon fabric.
DWR: The Secret to Water-Resistant Nylon
DWR, also known as water-repellent finish, is a coating applied to the surface of nylon fabrics that alters the fabric's surface tension. Rather than allowing water molecules to form beads and roll off, DWR treatment creates a microscopic layer that causes water droplets to bead up and slide off, preventing them from penetrating the fabric.
Measuring Water Resistance: The Importance of Hydrostatic Head
The effectiveness of DWR treatments is often measured by a metric called hydrostatic head (HH). HH is expressed in millimeters and indicates the pressure at which water can penetrate a fabric. A higher HH rating indicates greater water resistance, with values of 1,000 HH or more considered waterproof or near-waterproof.
Maintaining the Water Repellent Properties of Nylon Jackets
Regular care and maintenance are crucial for preserving the water repellency of your nylon jackets. Here are some tips to keep your jacket at its best:
-
Machine Wash in Cold Water: Use a mild detergent and a cold water setting to avoid harsh chemicals that can damage the DWR coating.
-
Drying Method: Air-dry your jacket whenever possible. Avoid drying it in a tumble dryer, as the heat can break down the DWR treatment.
-
Reapply DWR Treatment: After regular wear or extended periods of storage, the DWR coating may diminish. Reapplying a DWR spray or liquid can restore the jacket's water-resistant properties.
-
Avoid Harsh Chemicals: Avoid exposing your jacket to harsh chemicals, such as solvents or strong detergents, as these can damage the fabric and DWR coating.
-
Regular Inspection: Regularly inspect your jacket for tears or worn areas, as these can compromise its water resistance.
Nylon's Versatility and Water-Resistant Applications
Nylon's water-resistance, coupled with its durability and breathability, makes it an ideal choice for a wide range of outdoor apparel. Whether you're hiking in light rain, cycling through showers, or simply needing a windbreaker for brisk walks, nylon jackets offer the perfect combination of protection and comfort.
Conclusion
Nylon, in its natural form, is not waterproof. However, through the application of DWR treatments, nylon can be rendered water-resistant, providing protection from light rain or drizzle. By following proper care and maintenance guidelines, you can ensure your nylon jackets retain their water repellency and continue to serve you well in various outdoor activities.
