The influence of polymeric shrink-resist finishes on the durability on wool of fluorochemical stain and soil repellents was examined. In some cases the durability to washing, drycleaning, and abrasion of the fluorochemical (as judged by oil and water-repellency tests) was improved. The best results were obtained by addition of FC-234 (3M Company) to Sirolan BAP pad treatments. This combination also showed improved durability on cotton and polyacrylonitrile when cured with organo metallic catalysts.
