Abstract
A method for preventing discoloration of durable press fabrics containing cellulosic fibers that have been previously finished using a non-formaldehyde finishing agent such as glyoxal in which the fabric is treated with an oxidative afterwash solution at elevated temperature followed by neutralization, rinsing and drying. The oxidative afterwash treatment may be performed in a continuous process as part of or immediately following the durable press finishing operation, or at a later time in a totally separate process.
