【摘要】 四组纱线以45°角相互交织,在交织点处呈"米"字形结构的织物,称之为平面四轴向机织物。平面四轴向机织物由于斜纱的存在,具有各向均匀性好、耐冲击性优良、形态稳定性好等优点。对相同面密度的四轴向机织物、叠层四向机织物和常规机织物的厚度和顶破强力进行了试验对比分析。结果表明:平面四轴向机织物的厚度大于常规机织物,但小于叠层四向机织物;平面四轴向机织物的顶破性能明显优于叠层四向机织物和常规机织物。更多还原

【Abstract】 Woven by interlacing four sets of yarns ends at 45° angles,formed a "米"shape in the interlacing point,a tetra-axial fabric is fabricated.Because of the existence of the bias yarns,the tetra-axial fabric has the similar tension in all directions,excellent impact resistance,good stability of fabric structure and so on.The tetra-axial fabric,the quadri-directional laminated fabric and the conventional woven fabric are compared in their bursting property and their thicknesses,on the condition they have the same areal density.The results show that the thickness of tetra-axial fabric is bigger than that of conventional woven fabric,and smaller than that of quadri-directional laminated fabric.Meanwhile,its bursting property is obviously better than that of quadri-directional laminated fabric and conventional woven fabric.更多还原
