机织织物的产品参数，如编织、线密度、纱线密度和卷曲，决定了渗透性、渗透性和在聚合物复合结构中用作增强织物。然而，将这些参数与机织纺织品的渗透性联系起来的尝试很少。在这项研究中，19织造玻璃纤维纺织品被选中，以确定的编织，线密度，纱线密度，和卷曲的影响，在平面渗透性。测量已经进行了一个刚性的双面铝工具与八个线性电容传感器。本文用经纬纱的卷曲解释了各向同性组合织物的各向异性流动行为。具有较高卷曲比（经/纬）的织物分别显示出较高的渗透各向异性。通过比较三种相同结构的平衡和非平衡平纹织物和缎纹织物，发现了织物的编织密度（线密度和纱线密度的乘积）与渗透率-纤维体积分数曲线的斜率之间的关系，并观察到平纹织物的K2渗透率明显低于K1渗透率。因此，经编织物的各向异性更大。这项研究的结果允许选择和定制特定的，例如非常低或各向同性的，渗透性的机织纺织品。
Product parameters of woven textiles like weave, linear density, yarn density, and crimp determine permeability, infiltration, and use as reinforcement textile in a polymer composite structure. Nevertheless, attempts to link these parameters to the permeability of woven textiles are rare. In this study 19 woven glass fiber textiles were selected to determine the effect of the weave, linear density, yarn density, and crimp on in-plane permeability. The measurements have been conducted on a stiff two-sided aluminum tool with eight linear capacitive sensors. The anisotropic flow behavior of isotropically built-up textiles is explained by using the crimp in the warp and weft yarns. Textiles with a higher crimp ratio (warp/weft) showed a higher anisotropy in permeability respectively. A relationship between the weaving density (defined as the product of linear density and yarn density) of a textile and the slope of the permeability-fiber volume fraction curve was found. In a comparison of three identically built- up balanced and unbalanced twill and satin weave textiles it was observed that the K2 permeability of twill weave textiles is significantly lower compared to the K1 permeability. Consequently, twill weave textiles are more anisotropic. The results of this study allow the selection and tailoring of woven textiles with specific, e.g. very low or isotropic, permeabilities.
