Abstract

This work deals with the development of nonwoven fabrics using spunlace technology. The work done by us is on hydroentanglement process of polyester, viscose and their blends including preparation process and characterization of the fabric. The material parameters such as type of fiber, blend ratio and process parameters like jet pressure were studied in this research. The performance characteristics of thus developed nonwoven fabric have been reported in terms of air permeability, mass per unit area, thickness, liquid absorbency time, liquid absorptive capacity and tensile strength. An expression for predicting the fabric properties as a function of the aforesaid process parameters has been developed. It is interesting to note that the output results predicted from the software showed a good correlation between predicted results and actual experimental results. There is decrease of liquid absorption capacity was found with increase in jet pressure whereas increase in jet pressure increases fabric breaking load.

摘要

这项工作涉及使用水刺技术的非织造布的开发。我们所做的工作是关于聚酯，粘胶纤维及其混合物的水力缠结过程，包括制备过程和织物特性。研究了诸如纤维类型，混合比和喷射压力等工艺参数的材料参数。已经报道了这样开发的非织造织物的性能特征，涉及透气性，每单位面积的质量，厚度，吸液时间，吸液能力和拉伸强度。已经开发出一种用于预测作为上述工艺参数的函数的织物特性的表达式。有趣的是，从软件预测的输出结果显示预测结果与实际实验结果之间具有良好的相关性。随着射流压力的增加，发现液体吸收能力降低，而射流压力的增加则增加了织物的断裂负荷。
