Permanent press

Description

A finishing process in which a fabric is chemically treated to increase its wrinkle resistance. Permanent press finishing is usually accomplished by impregnating the fiber with a thermosetting resin. Once the fabric is sewn and pressed, the garment is heat treated to set the shape. The thermosetting resin is usually made from formaldehyde and maleic anhydride. One chemical process crosslinks cellulose with dimethylol carbamate. An alternative to chemical treatment is to blend natural fibers with crease resistant synthetic fibers such as polyester, nylon, or acrylic.
