ABSTRACT

The functional properties of jute adhesive-bonded 120 g/m² nonwoven fabric were studied considering three process parameters, i.e. adhesive concentration, squeezing pressure, and curing temperature using central composite rotatable design considering the use of that fabric in disposable light-weight carry bag. Mathematical models have been proposed for each functional property. The models can be used to predict and discuss the properties satisfactorily. The contour diagrams help to design a jute adhesive-bonded fabric for carry bag. To get the optimum functional properties of 120 g/m² fabric, the process parameters was 20% adhesive concentration, 1.2 N/cm² squeezing pressure and 120°C curing temperature. Comparison with commercial fabric showed that the properties of the developed fabric are better for using as carry bag. The performance of the developed bag in hanging test, repeated wetting test, drop test, and atmospheric test is better compared to commercial plastic carry bag. The developed PVA bonded jute nonwoven disposable carry bags as compared to plastic carry bag are heavier in weight, costlier and prone to more moisture absorption not having any water-repellent/water proof character.

摘要

研究了黄麻胶粘 120 g/m ²无纺布的功能特性，考虑了该织物在一次性轻便手提袋中的使用，考虑了该织物的粘合剂浓度、挤压压力和固化温度三个工艺参数，采用中央复合可旋转设计。 . 已经为每个功能特性提出了数学模型。这些模型可用于令人满意地预测和讨论属性。等高线图有助于设计用于手提袋的黄麻粘合织物。为获得 120 g/m ²织物的最佳功能性能，工艺参数为 20% 粘合剂浓度，1.2 N/cm ²挤压压力和120°C固化温度。与商业织物的比较表明，开发的织物的性能更适合用作手提袋。与商用塑料手提袋相比，开发的袋子在悬挂测试、反复润湿测试、跌落测试和大气测试中的性能更好。与塑料手提袋相比，开发的 PVA 粘合黄麻无纺布一次性手提袋重量更重，成本更高，并且更容易吸湿，没有任何防水/防水特性。
