Fabric & Apparel After Wash Stability Testing
At SR Labs, we know that a product’s true quality is proven not when it’s new, but after it has been used and washed. Our comprehensive After Wash Stability Testing services are designed to rigorously simulate real-world washing conditions to ensure your fabrics and apparel maintain their quality, appearance, and integrity. This crucial testing helps you guarantee customer satisfaction, minimize returns, and protect your brand’s reputation.
Our Key Analytical Tests
SR Labs uses internationally recognized standards, including AATCC and ISO methods, to deliver accurate and reliable results. Our key analytical tests include:
Dimensional Stability
The Process: We mark a precise grid on the fabric, wash it according to a specified method (simulating a home laundry machine), and then re-measure the dimensions to calculate the percentage of shrinkage or growth.
Colorfastness to Washing
The Process: A fabric sample is washed with a multi-fiber swatch (containing different fiber types like cotton, wool, and nylon). After the wash, we use a Gray Scale to visually grade both the color change of the original fabric and any staining on the multi-fiber swatch.
Appearance Retention
Pilling: We test the fabric’s resistance to forming small, unwanted balls of fiber (pills) on its surface.
Seam Puckering: We check for undesirable wrinkling or puckering along the seams, which can affect a garment’s fit and look.
Skewing
We measure for fabric twisting, which can cause a T-shirt’s side seams to shift towards the front or back after washing.
Why is After Wash Stability Testing Essential?
- Confirm Product Durability: We test for how well the fabric withstands repeated washing cycles.
- Ensure Consistent Sizing: We verify that your garments will not shrink or grow beyond acceptable industry standards.
- Uphold Brand Quality: We help you prove that your products are made to last, building confidence and loyalty with your customers.
