Synthetic fabrics are singed with more care than cotton because

  • A.they contain no size whatever
  • B.the melted fibre ends form hard beads
  • C.they burn a very great deal more slowly
  • D.they cannot be quenched at all

Answer: B

Polyester melts rather than burning cleanly, and the beads pick up dye differently and feel harsh. Blends are often singed after dyeing for this reason. Speed and flame setting both need adjusting. Cotton burns to ash rather than melting.
