Title: Improvements in or relating to the bleaching of cellulosic material
Inventor: WHITE WILFRED ARTHUR STEPHEN
IPC: D06L4/70
Filed: 1952-03-03
Abstract: Cellulosic material is bleached with a hot aqueous solution of an alkali or alkaline-earth metal chlorite applied in at least two stages, each two stages being separated by an alkali scour.  The material may be subjected to a preliminary desizing, scouring or chlorination.  A preliminary chlorination may comprise treatment with an acid aqueous hypochlorite solution followed by neutralization with an alkaline solution of an alkali-metal sulphite, bisulphite or thiosulphate, or it may comprise treatment with hypochlorite in two stages, the first at a pH below 8.0 and the second at a pH above 8.0, the two stages being either separate treatments or a single treatment in which the pH of the bath of the first stage is increased without removing the material.  After the alkali scour and before the second chlorite stage the material may be treated with an acid or neutral hypochlorite solution followed by antichlor treatment or neutralization and rinsing. The material may be washed after each operation.  The chlorite baths may comprise solutions of sodium chlorite buffered to a constant pH between 4 and 5.5 with a solution of sodium acetate in acetic acid or with sodium dihydrogen phosphate. The temperature of these baths may be between 70 DEG  and 95 DEG  C. A weak solution of sodium silicate, sodium hydroxide or sodium carbonate may be used for the alkali scour.  In a typical example, a linen fabric is scoured in soda ash solution at 100 DEG  C., rinsed, treated with a solution of sodium hypochlorite and acetic acid at 20 DEG  C., washed and neutralized with caustic soda, rinsed and treated at 95 DEG  C. with a solution of sodium chlorite, sodium acetate and acetic acid; this sequence of steps is then repeated.  Jute, hemp or cotton fabrics may also be treated.  Specifications 648,632 and 662,890 are referred to.
