Abstract
Textile materials and articles are bleached to a "dead white" by immersing them in a vat in a solution containing sodium chloride, a peroxide such as hydrogen or sodium peroxide, and sodium sulphate. If the materials are also to be cleansed, detergents comprising fixed alkalis, sodium or potassium hydrate, and sodium carbonate are added. The contents of the vat are boiled and then the materials are rinsed in hot and cold water successively. If the materials are to be dyed, a water solution of a dye paste such as "sky-blue" dye is added to the cold water rinse and the materials are allowed to stand for about five minutes. The contents of the vat are then heated to about 130 DEG F. and left for a period sufficient to produce the desired shade.
