Cotton Mercerizing: What It Is, What It Does to the Fiber and How to Control the Process
Mercerizing treats cotton yarn or fabric with concentrated caustic soda under tension. It gives luster, strength, dimensional stability and higher dye uptake when concentration, temperature, time, tension and washing are under control. The process variables, the difference from causticizing, how to check the result and the usual defects.
