Abstract

Textile comfort is found to be directly related with the fabric’s hydrophilicity; therefore, polyester properties are intended to be improved through its surface modification. Considering the glycerol’s hygroscopic properties, different treatments are assayed by bath exhausting in a microwave or a thermostatic bath. In both, glycerol’s fixation in the fabric is pursued. In this way, the use of NaOH 1 M is contemplated, as well as a plasma pretreatment that generates free radicals in the fabric’s surface. The main goal is that the given hydrophile properties remain permanent at the fabric and are not eliminated after rinsing with water.
All PES fabrics, submitted to different treatments, are characterized. In particular, the water vapor absorption capacity is evaluated, simultaneously with the wicking properties, the glycerol’s retention, the sorption kinetics, and the breathability of the fabric. It is observed that all treatments enhance the fabric’s comfort, although a low permanence is achieved. Moreover, alkaline treatments affect the mechanical properties. Regarding plasma pretreatment, PES hydrophilicity is increased, despite its reactivity is insufficient to retain glycerol.
