Ramie, tension-mercerized ramie, slack-mercerized ramie, and cotton fabrics are treated with 1,2,3,4-butanetetracarboxylic acid (BTCA) to obtain wrinkle-resistant properties, and their physical properties are compared. Tension mercerization slightly enhances the loss of both tensile and tearing strengths of the crosslinked ramie fabric, while slack-mercerized crosslinked ramie fabric has severe mechanical strength loss mainly due to the destruction of fiber orientation during mercerization. Both the tension- and slack-mercerized crosslinked ramie fabrics show increased moisture and water retention, as well as a very rigid handle. Both tension and slack mercerization minimize surface migration of the crosslinking agent.
