Inexpensive.
Runs at lower temperature.
Requires less alkali than other forms of bleaching to achieve the desired pH.
Less bleaching time.
Bleaches much slower than calcium hypochlorite.
It is already in a liquid form; therefore, solubility is not a problem as it is with calcium hypochlorite.
It penetrates the seams and double folds easier than calcium hypochlorite and gives a more uniform bleach. This is very apparent on the hip pockets.
At an acid pH dangerous gases are liberated.
Corrosion-resistant equipment preferably 316 stainless steel (not 304 stainless steel) is necessary.
The chemical strength is affected by ultraviolet rays, extreme heat or extreme cold; therefore, the storage life is very short. Titration for bleach strength of sodium hypochlorite needs to be conducted each shift and dosages adjusted accordingly.
Uneven bleaching of the garments will result if you bleach at a pH of 8 or lower.
Oxidative degradation of cotton fiber if the bleach is left on the fiber at neutral to acid pH.
Garments will yellow if the hypochlorite is not completely neutralized.
Can damage synthetic fibers.
Harmful to skin in concentrated form.
Adversely affects tensile strength if process is not controlled.
