- Abstract
The utilization of an argon-ion laser in low heat fixation of fiber reactive dye was explored. Dyed fabric was moved at three velocities past a fixed laser beam to achieve fine-line dye fixation at temperatures of 235C, 129C, and 94C. Laser treated specimens were compared to specimens fixed by a conventional hand iron and to control groups. Washfastness and lightfastness were evaluated by five raters and tensile strength was measured. The results of a factorial analysis of variance showed significant differences at the 0.05 level in the washfastness properties between laser treatments at 129 and 235C and laser treatment at 94C and hand iron treatment. Infrared spectroscopy data of laser treated, hand ironed and control samples showed no notable difference in the molecular structure of the substrates, indicating that no unique chemical bonds were formed due to laser treatment. Results suggest that in some cases, laser heat fixation is simply a more effective way to set fiber reactive dyes.
