Influence of Mole Ratio and Pressure on Properties of UHMWPA6/GdCl₃ Fiber by Dry-Spinning Method

Abstract:

In this work, the solution of PA6/GdCl3 with different complex ratios were prepared, using gadolinium trichloride (GdCl3) as complexing agent, formic acid and hydrochloric acid as solvent. The fibers were then prepared by dry spinning method and characterized with scanning electron microscope (SEM), Fourier transform infrared (FTIR) spectroscopy and Instron tensile testing. The results indicated that fibers with good morphology and mechanical properties could be obtained when mole ratio (MR) was 0.04 and PA6 concentration was 22wt%. Moreover, we found that spinning pressure had significant influence on the properties of fibers.
