Bleach is the generic name for any chemical product that is used industrially or domestically to remove color from (i.e. to whiten) fabric or fiber (in a process called bleaching) or to disinfect after cleaning.
They include the following chemicals: sodium hypochlorite (active agent in bleach), chloramine, halazone, and sodium dichloroisocyanurate. [2] They are widely used to disinfect water and medical equipment, and surface areas as well as bleaching materials such as cloth. The presence of organic matter can make them less effective as disinfectants ...
The textile bleaching (or bleaching of textiles) is one of the steps in the textile manufacturing process. The objective of bleaching is to remove the natural color for the following steps such as dyeing or printing or to achieve full white. [1] All raw textile materials, when they are in natural form, are known as 'greige' material. They have ...
Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as chlorine bleach, which is a household chemical widely used (since the 18th century) as a disinfectant and bleaching agent.
Its bleaching action is based on ''destroying the phenolic groups and the carbon–carbon double bonds.''. [6] A major source of chemical bleaching is hydrogen peroxide (H 2 O 2) that contains a single bond, (–O–O–). When the bond breaks, it gives rise to very reactive oxygen specie, which is the active agent of the bleach.
It is known as a bleach activator for active oxygen sources, allowing formulas containing hydrogen peroxide releasing chemicals (specifically sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide) to effect bleaching at lower temperatures. [1]

These materials must be removed between bleaching stages to avoid excessive use of bleaching chemicals, since many of these smaller molecules are still susceptible to oxidation. The need to minimize water use in modern pulp mills has driven the development of equipment and techniques for the efficient use of available water. [13]
