Abstract: Co-woven-knitted (CWK) fabric and Multi-layered Biaxial Weft knitted (MBWK) fabric are produced with the same yarns and loop length, using glass filaments as inserted yarns and high tenacity polyester as stitch yarn. 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 strength comparison is made between the CWK fabric and MBWK fabric. The results revealed that inserted yarns bear high load in low elongation to failure, and then, the knitted structure commits the low load in high elongation until it damage. Interwoven between warp and weft yarns leads to large buckling of them, the strength of the CWK fabric is lower than the MBWK fabric, but the interwoven makes knitting yarn in a station of pre-draft, reflecting the knitting yarn being a the role of better bundled on warp and weft.
