石英纤维缎纹织物的剪切变形实验研究

摘要

在改进像框实验的基础上，对5枚缎纹和8枚缎纹石英纤维机织物的剪切性能进行实验观察，分析不同组织结构、经纬纱密度对织物剪切性能的影响。研究发现：在相同结构参数条件下，8枚缎纹织物比5枚缎纹织物更容易发生剪切变形；织物组织结构相同时，经纬纱密度越大，织物越不容易产生剪切变形。基于缎纹织物的单胞模型预测了5枚缎纹和8枚缎纹石英纤维机织物的锁紧角，预测结果与实验值基本一致。%Based on the modified experiments for picture-frame , the in-plain shear properties of the 5 h-satin and 8 h-satin of quartz fiber fabrics are studied. The effects of fabric architecture and yarn density on shear properties of fabrics are analyzed . The results show that 8 h-satin fabrics are easier to form shear deformation than 5 h-satin when other conditions are the same. The fabrics are not easier to form shear deformation when the yarn density in-creases with the same fabric structure. Based on the satin fabric unit cell model , the locking angles of the 5 h-satin and 8 h-satin fabrics are predicted, the predicted values show good agreement with the experimental ones.
