Print paste is thickened chiefly in order to

  • A.increase the dye concentration in it
  • B.raise the fixation yield achieved
  • C.reduce the drying time that is needed
  • D.stop the design spreading on the cloth

Answer: D

Without a thickener the paste would wick along the yarns and the design would lose its edges. The thickener has to be washed out afterwards, which is a significant part of the water use in printing. Sharp edges are what a good thickener delivers.
