Bleaching of textiles

The textile bleaching 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. All raw textile materials, when they are in natural form, are known as 'greige' material.

They have their natural color, odor and impurities that are not suited to clothing materials.
Not only the natural impurities will remain in the greige material, but also the add-ons that were made during its cultivation, growth and manufacture in the form of pesticides, fungicides, worm killers, sizes, lubricants, etc.
The removal of these natural coloring matters and add-ons during the previous state of manufacturing is called scouring and bleaching.
