Mercerised cotton takes up more dye than untreated cotton because

  • A.the fibre is very much thinner
  • B.the swollen cellulose is more accessible
  • C.the fibre surface becomes rougher
  • D.the caustic remains inside the fibre wall

Answer: B

Dye yield can rise by a quarter or more for the same application, which is a real saving. It also means mercerised and unmercerised goods cannot be dyed in the same bath to the same shade. Yield can rise by a quarter or more.
