摘　　要：合理的弯曲刚度使得汽车座椅面料在缝合过程中不易出现缝合位缩皱,在使用过程中不容易起拱变形,因此它是评价汽车座椅面料质量的一个重要指标。采用LLY-01型电子硬挺仪,对影响针织结构汽车座椅复合面料弯曲刚度的因素进行测试分析。结果表明,对于同种纤维原料的汽车座椅复合面料,面料面密度、海绵厚度、面料密度、花色组织等都对面料的弯曲刚度具有一定的影响;其中由于海绵的复合,面料密度的影响不再占主要地位。Appropriate bending rigidity enables the knitted automotive upholstery materials to avoid the sewing place wrinkling , and decrease the chance to be out of shape when they are used .It is an important indicator to assess the quality of automotive upholstery materials .The bending rigidity was tested by the LLY-01 Fabric Stiffness Tester and the factors , affecting the property of knitted composite fabric , were analysed .The results show that the weight per square meter , the sponge thickness , the fabric density as well as fabric structure affect the bending rigidity of the composite fabrics with the same fiber .However, the fabric density plays little part in the bending rigidity of the composite fabrics because of the sponge .
