Abstract: The relationship between magnitudes of the instrumental measurement of the elastic recovery properties and some yarn parameters has been studied. In general, the coarse yarns have low immediate elastic recovery, high delayed elastic recovery, and a large permanent set than the fine yarns prepared under the identical processing conditions. The use of higher first nozzle pressure and main draft produces high immediate elastic recovery but low delayed elastic recovery and permanent set. Both amplitude and rate of extension produce a large variation in the elastic recovery properties, the magnitude being dependent mainly on processing factors.
