3D warp interlocks p-aramid fabrics for composite reinforcement and ballistic vest applications: Effect of yarn density on its formability characteristics

摘要

The material forming capability becomes one of the most important characteristic of textile performance in the manufacturing of three-dimensional (3D) components to fit a 3D surface in various technical applications. In this study, different forming characteristics of 3D warp interlock fabrics in dry fabric condition were investigated. 3D warp interlock architecture with different areal density from same para-aramid yarn with a linear density of 168dtex were systematically designed and produced on automatic dobby loom with standard atmospheric conditions. The approach utilizes a low speed forming process with a predefined hemispherical shape of punch for the analysis of different forming behaviour of the fabrics specimen. The same blank-holder pressure was chosen for all the samples for better comparisons. Among several forming properties, some important characteristics have been observed, measured and analysed for a better understanding of the material forming behaviour of the different samples specimen. The research results with independent warp and weft yarn densities show a significant impact on the forming behaviours 3D warp interlock fabric. Moreover, the result of the investigation also will give a better understanding on different forming behaviours of 3D warp interlock fabric with various densities while applying in different textile application including women soft body armour.
