Before cotton and linen are immersed in bleachingchemicals, such as natural impurities as wax and oilmust be removed.

The cloth is scrubbed and boiled in large kettles,

known as kiers. It is then placed for bleaching in a water solution of

sodium hypochlorite or calcium hypochlorite.

The hypochlorite ion, or the chlorine formed by the

decomposition of hypochlorite ions, oxidizes thenatural gray or brown coloring matter of the cloth,changing it into a colorless compound.

As a result the textile becomes white.
