Effect of alkaline treatment on the physical and tensile properties of jute/polyester interwoven fabrics

Purpose The aim of this study is to investigate the effect of alkaline treatment of jute/polyester interwoven fabric with different concentration levels (0, 2, 4, 6%) on some properties such as the weight changes, water adsorption time, moisture content, vertical wicking, bending and tensile properties. Design/methodology/approach The plain weave jute/polyester fabric was interwoven using jute and filament polyester yarns in the warp direction (1:1 ratio) and jute yarns in the weft direction using a shuttle weaving machine. Jute/polyester fabrics were treated with different concentrated solutions of NaOH (0–6% w/v) in an aqueous medium with soaking time of 60 min at room temperature. After soaking, jute/polyester fabrics were washed with deionized water twice. Jute/polyester fabrics were then. After drying, jute/polyester fabrics were kept in a desiccator for the following tests. To compare the properties of untreated and treated samples, some properties were evaluated. Findings The results indicated a decrease in weight and bending rigidity with increasing NaOH concentration. In general, alkali treatment of jute/polyester interwoven fabrics improved the handle properties, moisture content and wicking capabilities, but this treatment decreased the tensile strength of the fabric. Originality/value Study of the effect of alkaline hydrolysis on jute/polyester interwoven fabrics This treatment will have dual effects on the fabric, namely, the changing of jute fibers and the hydrolysis of the polyester component.
