To waterproof polyester pants, you typically apply a Durable Water Repellent (DWR) treatment, often in the form of a spray. This process helps the fabric shed water effectively.
Polyester is a synthetic fiber known for its durability and resistance to stretching and shrinking. While some polyester fabrics might have inherent water-resistant qualities or be treated during manufacturing, a common method to enhance or restore waterproofing is using a DWR finish.
Here's how to apply a DWR spray to your polyester pants, based on the provided reference:
Steps to Apply DWR Spray
Applying a DWR treatment is a straightforward process that you can do at home. Follow these steps for the best results:
- Clean and Dry: Before applying any treatment, make sure the garment, shoes or bag is clean and dry. This is crucial because dirt and residues can prevent the DWR from bonding properly with the fabric fibers.
- Apply Spray: Spray an even layer of DWR spray over the garment or gear. Ensure you cover the entire surface you wish to waterproof.
- Wipe Excess: Let it air dry for a couple of minutes and then wipe away the excess liquid. This ensures an even coating and prevents potential residue buildup.
- Allow Complete Drying: Let the garment or gear air dry completely and wait about 24 hours before using. Full drying time is important for the DWR to properly cure and bond to the fabric, maximizing its water-repelling effectiveness.
Tips for Application
- Work in a well-ventilated area.
- Follow the specific instructions on the DWR product you purchase, as drying and curing times can vary slightly between brands.
- For heavily used or older pants, you might need to reapply DWR periodically as the treatment wears off over time and with washing.
Applying a DWR spray helps water bead up and roll off the surface of the pants instead of soaking in, enhancing their water resistance for wet conditions.
