Abstract: The relationship between the magnitudes of the instrumental measurement of the inverse relaxation and some yarn factors has been investigated. It is observed that the inverse relaxation index and load induced are influenced by the blend composition, yarn linear density and first jet pressure. In MJS yarns, a systematic decrease in yarn linear density greatly increases the inverse relaxation index. The use of higher first jet pressure produces higher inverse relaxation but reduces load induced. Also, the inverse relaxation index increases with the increasing retraction level but shows descending relationship with the increasing polyester content.
