Humidification plant in a textile spinning mill consumes energy in order to

  • A.dry the yarn after it leaves the ring frame
  • B.hold the relative humidity the yarn requires
  • C.cool the spinning machinery's bearings
  • D.remove dust from the spinning hall

Answer: B

Fibre breaks and static build up if the air is too dry, so the mill must be kept humid whatever the weather, and the plant may take a fifth of the mill's electricity. Controlling it to the actual requirement rather than a fixed setting is the saving.
