unbleached linen is produced by a solution of a hypochlorite 

 which contains no free alkali, but rather some free chlorine or 

 hypochlorous acid. Excess of alkali retards the bleaching action, 

 just as it does in the case of other colouring matters. The 

 addition of a chloride to the solution sometimes accelerates and 

 sometimes retards the bleaching action (this depending upon 

 the amount of alkali in the solution), instead of, as is the case 

 with other colouring matters, always accelerating it.
