Abstract
Three test methods were developed and validated to assess the repellency performance of repellent cotton fabrics using a number of test liquids with low and high surface tensions, from 22 mN/m to 72 mN/m. These methods were assessed using cotton fabrics coated with a diblock copolymer made of a sol-gel block which grafts the polymer to the cotton and a fluorinated block which imparts the liquid repellent properties.
