摘要: 选用玻璃纤维作经纱、纬纱和高强涤纶作针织纱编织机织针织复合织物,测试这种织物的横向、纵向的拉伸性能,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、纬纱的屈曲和针织纱的穿套均影响了纱线强力的利用。

Abstract: Co-woven-knitted (CWK) fabric is produced 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 results revealed that woven structure bear high load in low elongation to failure, and then, the knitted structure commits the low load in high elongation until it damage. Interweaving between warp and weft yarns leads to large buckling of them and low strength utilization for warp and weft yarns. Intermeshing of stitch yarn also leads to low strength utilization for stitch yarn.
