A Novel Approach for Improving Wrinkle Resistance and Flame Retardancy Properties of Linen Fabrics

Abstract

Flax is an important fibre for textile industry not least because of its excellent properties. However, in its untreated form, linen fabrics possess poor wrinkle resistance and burn easily with a high flame velocity. Linen fabrics functional finishing researchs have been mainly focused on reducing these problems to achieve the desired fabric property for using its as wearing apparel, household textile and composite material. This study was undertaken to investigate the novel durable wrinkle resistant and flame retardant finishing of the linen by using 1,2,3,4-Butanetetracarboxylic acid, Nano polyurethane for cross-linking and Al₂O₃ nanoparticles for catalyst in padding process. Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy with Energy Dispersive X-ray analysis were used to characterization. Colour difference, whiteness and yellowness analysis was performed on the linen fabrics before and after the chemical treatment. Tensile strength tests of the warp and weft yarns were performed to evaluate the effect of finishing treatment. With the chemical treatment, linen fabrics wrinkle resistant and flame retardant properties enhanced. The durability of the functional properties were also tested after 5 washing cycle.
