Abstract

In this research, the effect of some drawing parameters on the physical properties of polyester filament yarn was investigated. Heating operations were carried out with two methods: simultaneous (heating with drawing) and sequential (heating after drawing). The results showed that the tenacity and initial modulus of PET yarns increased with increasing the draw ratio at a selected optimum heating operation. The simultaneous method gives rise to the resultant drawn yarn with superior tensile properties and low shrinkage.
