Soil and Stain Release Performance
topic
Soil release testing applies standardised stain agents including oil, lipstick, and food colorants to fabric specimens that are then laundered under specified conditions; residual stain is graded against AATCC stain release replicas from 1 (no release) to 5 (complete release) to quantify wash-off efficiency.
Role
Validates easy-care and soil-release finishing treatments on polyester and polyester-cotton blend workwear, hospitality textiles, and childrenswear where stain removal efficiency in domestic laundering is a primary consumer performance expectation.
