All of the following are effects of mercerisation EXCEPT

  • A.increased water repellency
  • B.increased lustre
  • C.increased dye uptake
  • D.increased tensile strength

Answer: A

Correct answer: increased water repellency

Mercerisation does the opposite: the swollen, more accessible cellulose absorbs water more readily, which is part of why it takes up dye better. Lustre, dye uptake and tensile strength all increase, and so does dimensional stability - but nothing about the process makes the fibre hydrophobic.
