Mercerisers

Mercerising can be done at different stages during the pre-treatment process. This could be after De-sizing or after Scouring or after Bleaching. When done after desize-washing, it induces maximum lustre onto the fabric. However, contamination of lye can occur, which reduces life of the caustic lye. High degree of whiteness can be achieved if the bleaching process is done after mercerisation. Mercerisation after scouring and bleaching prevents contamination of caustic lye but effects the whiteness and absorbency. Mercerising can be done either on wet fabric with a lye concentration controller or on dry fabrics. Mercerising could be done with either cold lye or with hot caustic.
