Tensile properties of co-woven-knitted fabrics

According to the structural features of co-woven-knitted fabric(CWK),the fabric is produced using glass filaments as warp and weft and high tenacity polyester as knitting yarn.For exploring application fields of CWK fabrics,tensile tests are carried out in the wale and course directions.The mechanical properties of the fabric are investigated by analyzing the stress-strain curves.The results reveal that woven structure bears high load in low elongation to failure,and then,the knitted structure commits the low load in high elongation until it damages.Interweaving between warp and weft yarns leads to large buckling of them and low strength utilization for warp and weft yarns.Intermeshing of knitting yarn also leads to low strength utilization for knitting yarns.
