Answer» a) Four factors need to be kept in mind before choosing the process of washing: Fiber contents Type of yarn Fabric construction techniques Finishes used b) Two types of circulation systems: Air of relatively low temperature is circulated at high velocity: the air present in the room enters a drier from under the front panel, passes over the heat source and then through clothes and leaves through an exhaust and therefore the temperature and humidity of the room stays normal. Air at high temperature is circulated slowly: In this, after the air enters the drier and passes over the heat source, it is drawn by a small fan through perforations at the top of the drier, then downwards through the clothes and out through the exhaust. Since the movement of the air in this drier is slow, the relative humidity of the exhausted air is high.
