1 Madder Bleach
The most thorough bleach that cotton cloth receives. The process takes about four days and consists of several long boilings with alkalies and a final treatment with bleaching powder. It gives a full white and is generally used for goods to be printed. The usual procedure is as follows: - (1) Singeing to burn off all loose fibre. (2) Grey soaking, a simple steeping in water. (3) Lime boil, boiling in lime water for about ten hours under pressure, then washed in water. (4) Lime sour, a washing in cold acid solution of about 1 per cent strength. (5) and (6) Lye boilings in dilute solutions of caustic soda with resin soap for about ten hours. The sixth operation omits resin soap. (7) Chemicking, treatment in cold dilute solutions of bleaching powder, afterwards washing in water. (8) White sour, treatment in cold dilute acid solution as in No. 4. (9) Thorough washing in water and then drying. -
