This study investigates the influence of 3D weft-knitted fabric fibre composition on the risk of puncture
and tear and evaluates the air permeability of these protective knits. For this purpose, different 3D weftknitted
fabrics, consisting of outer (protective), binding, and inner (suitable for contact with skin) layers,
were produced on an E20 circular weft-knitting machine using different quantities of high molecular
weight polyethylene (HMWPE) (from 49% to 24%) and inorganic yarns (from 0% to 23%) in the outer
layer while the quantity of polyester in the inner layer and polyamide in the binding layer was kept the
same. The puncture and tear resistance tests were conducted to determine the resistance of the 3D weftknitted
fabrics to mechanical risks. The air permeability test was performed to assess the comfort
properties of the protective 3D weft-knitted fabrics. According to the puncture and tear resistance testing
results, it was determined that the highest HMWPE percentage content in the outer layer of 3D weftknitted
fabric provided the highest resistance to these mechanical risks. Based on the air permeability
test results, it was found that knit with the highest inorganic yarns content in the outer layer achieved
the highest air permeability value.
