Clues

  • Application of starch or polymers to stabilise warp yarns to reduce breakages. (3, 7, 6)
  • Changing the shape of the cotton fibre (swelling) by impregnating with ~22% sodium hydroxide solution. (13)
  • Mechanical. Improves wettability by burning off surface fibres. (8)
  • Oxidation or reduction of the yellow chromaphores in cotton. Typical bleaching agents: hydrogen peroxide, sodium chlorite, sodium hyphochlorite. (9)
  • Removal of natural and added impurities by various processes depending on cotton type. (8)
