A process for producing sodium bicarbonate and sodium carbonate. The process includes reacting within a reactor sodium sulfate in aqueous solution with ammonia and carbon dioxide to precipitate sodium bicarbonate and form a first mother liquor. The sodium bicarbonate is separated and dried to produce sodium bicarbonate product.

Scouring is the third steps of pre-treatment. This process is performed for removing impurities of the textile materials. Bleaching is another important step which is used to reduce natural color of the raw materials. Dyeing performance depends on it much more. Mercerizing is the special types of treatment.
