摘　　要： 根据新型机织针织复合织物的结构特点,选用玻璃纤维作经纱、纬纱和高强涤纶作针织纱编织了这种织物。为提供这种新型织物的应用依据,测试织物的横向、纵向拉伸性能,分析比较拉伸负荷和位移特征曲线。研究表明:机织针织复合织物在拉伸过程中,先由其中的机织结构在较低的伸长下承担较高的负荷,直至机织结构破坏,然后由针织结构在较高的伸长下承担较低的负荷,直至针织结构破坏;经纱、纬纱的屈曲与针织纱的穿套均影响纱线强力的利用。 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.
