    Development of 2.5D Multi-Layer Stitched Woven Anti-Ballistic Fabric on a Conventional Handloom
    (University of Management and Technology, 2017) Shahid, Arooj
    Anti-ballistic armours are of vital importance for personal protection equipment. High-tech organic aramid fibres are chiefly used for imparting anti-ballistic properties. In recent times, 3D weave emergence, in the technical textiles sector is on the run of uncurtaining vast novel opportunities and advancements. The research focuses on developing 2.5D multilayer stitched woven fabric on a conventional handloom, incorporating technical yarns for imparting anti-ballistic properties. Multifilament Kevlar® 49 having a linear density of 1420 denier was used as technical material. Samples of four, six, eight and ten layer stitched multilayer weave structures were successfully drafted and fabricated on a conventional handloom, in addition to a plain weave sample. The increased number of layers displayed gradual increase in the thickness generating a compact stitched fabric construction. As, more the layers better will be the impact resistance and greater will be the energy dissipation The stitched weave structure design may compensate the varied ends spaced open construction with higher number of picks to form a considerable thickness. In future it may fulfil the anti-ballistic performance and impact resistance properties followed by further ballistic testing and manufacturing such multilayer stitched woven body armour on high speed mechanical looms.
