The aim of this study was to investigate the effect of crease resistant treatment on sewability and seam properties of cotton shirt fabrics. The effects of the fabric construction (plain, twill, and satin weaves), the concentration of crease resistant chemical, and the stitch density were investigated in terms of seam quality and sewability. Seam efficiency was calculated and the appearance of seams and creases were evaluated using standard methods. Furthermore, the sewability of the fabrics was measured with an L&M sewability tester. The results were then statistically evaluated. It was found that crease resistant treatment improved the seam efficiency, sewability, and appearance of creases, whereas no positive effect on seam appearance was observed.
In this study, 100% cotton fabrics' flame retardant properties were improved using commercial nanoclay (Cloisite 20A), clay-based montmorillonite. Flame retardancy and thermal decomposition behavior of the samples were characterized by the vertical burning test, limiting oxygen index (LOI), and thermogravimetric analysis (TGA). The surface morphology of untreated and treated fabric was examined using a scanning electron microscope (SEM). Fourier-transform infrared spectroscopy (FTIR) analysis was carried out for Cloisite 20A, untreated, and coated fabrics. The test results showed that the coating treatment, even at low nanoclay concentration, is enough to have a considerable flame retardant effect. This result was attributed to the barrier effect of the nanoclay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
