What is Durable Water Repellent (DWR) and how can it be tested?

In textile production, polymeric PFASs play a significant role in various applications, particularly as treatments that enhance the water, stain, and oil repellence of fabrics. This enhancement is commonly referred to as Durable Water Repellent (DWR) finishing. DWR finishing involves impregnating the fabric to prevent or delay water penetration, resulting in water-repellent, water-resistant, and waterproof properties. The test plan will evaluate the fabric's resistance to water and other liquids, as well as assess the durability of the treatment.

Test Item (Either One):

• Water resistance – Rain test
• Spray test
• Water resistance – Hydrostatic head (up to 5000mm)

What is Item Care and how can it be tested?

While garments endure abrasion and daily wear, the most significant damage occurs during washing and drying. Mechanical agitation, moisture exposure, and high temperatures can accelerate the breakdown of seams and materials over time. Testing will be conducted before and after care, you should follow the care label that accompanies your product. If your sample is expected for one-time use only or no cleaning procedures are allowed, please contact our experts for assistance.

• Washable – Test sample as received and after washes
• Drycleanable – Test sample as received and after commercial dryclean
• Washable & Drycleanable – Test sample as received, after wash and after commercial dryclean

Remarks:

The test items will be tailored based on your product type and target age range. Only specific tests will apply to the selected product type, test category, and destination market. A detailed list of test items will be included in the order confirmation email after your purchase.
