Investigate the effect of inlaid yarn on the mechanical properties and dimension stability of the weft-knitted double jersey structures for protective application

Abstract

Knitted fabrics finds wide applications in functional/protective areas, as the advancements in textile Industry happens. These fabrics were famous for their stretchable structure and soft feel. This study investigates the mechanical performance, stability, and puncture of weft knitted structures with and without inlay yarns. Specimens were developed using Jute and Flax yarn as inlay yarn while Kevlar® (para-aramid) and polyester yarn as main yarn. Main and inlay yarn effect on tensile strength, elongation, stretch and recovery, and puncture resistance was characterized. The results reveal that mechanical performance and stability of fabric were significantly increased with inlay yarn in the course direction. On the other hand, expansion was greatly reduced, but higher growth was observed in rib specimens without inlay yarn.
