Fluorinated repellent products provide stain, oil and water repellency on fabrics. These fluorinated repellent products, including durable water repellents (DWRs), are usually applied in combination with other finishing auxiliaries by a pad-dry-cure process. In many cases they are applied with “extenders” which can be other repellents themselves (e.g., hydrocarbons such as waxes) or crosslinkers (e.g., melamine and isocyanate or blocked isocyanates). The use of these “extenders” enhances repellent performance and allows a reduction in the required amount of fluorochemical, with a corresponding reduction in costs for this treatment. While these chemistries perform well on garments and equipment, they may be harmful if released to the environment. This document is intended to provide an overview of Best Environmental Practices (BEP) to help mills and finishers minimize waste and environmental release, and keep the products on the textile. Product specific steps provided by the manufacturer and legal requirements override the practices offered here, so always verify with your specific supplier what steps are appropriate to take at your facility.
