The polyester yarn samples have been treated in a rel axed state with variolls concentrations of TCAC mixture at room temperature for different durations. It is observed that the TCAC treatment causes significant changes in strell gt h and elongation behaviour of orig inal fine filament and microdenier polyester yarns. The solvent-treated yarns exhibit higher breaking elongation, improved work of rupture and lower ten ac it y. The improvement in elongation and work of rupture is found to be less in the case of heat-set polyester yarns due to th e subsequent TCAC treatment. The influence of treatment time a nd heat sellin g temperature on strength, elongation, yie ld behaviour and work of rupture of TCAC-treated yarns has al so been investigated.Read More
