玄武岩纤维针织物的尺寸特性

摘要

This paper was devoted to investigate the effect of fiber property on the dimensional properties of basalt fiber knitted fabrics, and the basalt fiber knitted fabrics with different structures of plain, 1 × 1 rib, full gauge 1 × 1 rib and Milano rib were made on V-bed machine in 5 sinking depths. The dimensional parameters of basalt fiber knitted fabrics were tested after relaxation to discuss the rule of dimensional change with time in cross, longitudinal directions and in fabric area. The regression analysis has shown that the fabric densities have linear relationship with the inverse of loop lengths. Meanwhile,the loop shape of the basalt fiber knitted fabrics was compared with that of wool/acrylic knitted fabrics.Since basalt fiber is high in bending rigidity, the loop shape of its knitted fabrics exhibited more flattened. By means of this study, the dimensions of the fabrics can be predicted before knitting.%为研究纤维性能对针织物尺寸特性的影响,在横机上编织了5种弯纱深度的平针、1+1罗纹、满针罗纹和米拉诺组织玄武岩纤维针织物.通过对松弛后织物尺寸参数的测试,分析玄武岩纤维针织物纵向、横向以及面积尺寸随时间的变化规律,并对织物密度进行回归分析.结果表明,玄武岩纤维织物密度与线圈长度倒数呈正线性相关的关系.比较了玄武岩纤维针织物与毛/腈针织物的线圈形态,由于玄武岩纤维具有较高的抗弯刚度,其针织物的线圈形态较为扁平.通过对玄武岩纤维针织物尺寸特性的研究,可实现织前对织物尺寸的预测.
