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.
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.
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.
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.
