Análise colorística de estampa plastisol, funcionalizada com pigmento fotocrômico

Abstract

The textile industry is constantly evolving and changing all the time, with new developments appearing in various sectors. What is most striking is the technological advances in various sectors such as dyeing, finishing, printing, among others. The printing sector is always looking for innovation in order to be competitive among companies, but also to deliver more comfort, style and aesthetics to its customers. Within the printing sector, there are various procedures for making a print on a fabric, but screen printing is able to functionalize a fabric through its procedure. In order to functionalize a substrate using the screen printing process, it is necessary to functionalize the plastisol paste with the photochromic pigment so that the procedure can be carried out. The screen printing was applied to a 100% polyester half knit. This study carried out the characterization of the 100% polyester stockinette according to ABNT standards NBR 10588 and 10591. To functionalize the paste, a concentration of 1% and 5% of photochromic pigment was used and washing fastness tests were carried out. After washing, color analysis was carried out at times of 0, 30 and 60 seconds, with the variation in stimulus time being 10, 30 and 60 seconds of exposure. After the coloristic analysis, it was possible to confirm that the prints produced with 2 layers have better fixation on the polyester mesh and high wash fastness.
