Notes:
Cotton/polyester fabrics were treated with 14C-labeled acrylic soil release polymers, either alone or with a durable press reagent, dimethyloldihydroxyethyleneurea (DMDHEU). Both two-bath and one-bath applications were used. Rate of removal of polymer in laundering was determined experimentally by radiotracer methods. Removal was faster in the order polymer alone (no DMDHEU) 〉 two-bath process 〉 one-bath process. The difference was much more significant when high molecular weight emulsion polymer was used than partially neutralized low molecular weight solution polymer. It is concluded that condensed DMDHEU serves as a coupling agent to bind polymer to fabric, thereby retarding removal of polymer in laundering. The significance of the results with respect to soil release of treated fabrics is discussed.
