Abstract:

This paper was devoted to investigating 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 comparing 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.
