Textile Term: Durable Water Repellent
Durable water repellent, commonly known as DWR, is a chemical treatment applied to fabrics and textiles to make them resistant to water. This treatment is applied to the surface of the fabric, creating a barrier that causes water to bead up and roll off the fabric instead of being absorbed.
DWR is commonly used on outdoor apparel and gear such as jackets, pants, and tents to protect wearers from getting wet in rainy or wet conditions. It is important to note that DWR does not make fabrics completely waterproof, but rather, water-resistant. Over time, the DWR treatment can wear off due to regular wear and tear, washing, and exposure to the elements.
DWR is typically made up of a fluorocarbon-based chemical compound, which has raised concerns about its environmental impact. Fluorocarbons are known to be persistent in the environment and have been linked to adverse health effects in humans and animals. In response to these concerns, some textile manufacturers have developed eco-friendly alternatives to traditional DWR treatments.
Overall, DWR is an important technology in the textile industry for providing water resistance to fabrics and textiles. However, it is important for manufacturers to consider the potential environmental impact of the chemicals used in DWR treatments and to explore alternative, more sustainable options.
