A fluorocarbon-free, durable water repellent (DWR) that keeps fabrics dry with high laundering durability. This DWR is based on hydrophobic acrylic polymer chemistry that crosslinks on the surface of fibers for excellent adhesion. The coating has good laundering durability, having achieved a “100” spray rating on polyester and nylon fabrics after 50+ home laundering wash-dry cycles. Similar to other DWRs, fabric is dipped in a bath of the DWR-water mixture, squeezed, and then thermally cured between 280 °F (138 °C) and 380°F (193 °C). The coating does not noticeably affect the appearance or handfeel of fabrics. Based on wash tests by the Hohenstein Institute, coated fabrics received AATCC spray ratings of 90–100 after 20 washes, and ISO spray ratings of 4–5. This DWR is also bluesign® approved. Applications include fabrics for apparel.
