摘要

Polyester is one of the important fibers among man-made fibers. One of the finishing processes for improving the performance of polyester fabrics is weight reduction treatment. This treatment has a considerable effect on the mechanical properties of such fabrics. In this research, the effect of weight reduction treatment on changes in the Poisson's ratio of a microfiber polyester woven fabric treated with four different sodium hydroxide concentrations was studied. Poisson's ratio of the fabric at 10 levels of extension was measured. Results show that from 1% to about 5%, the Poisson's ratio increases non-linearly. After this point up to 10%, the Poisson ratio decreases by a linear trend. There is a significant variation in the results at lower extensions, and by increase in extension, this variation reduces. Statistical analysis showed that weight reduction at percentages lower than 25% does not affect the Poisson's ratio of the fabric. In the range of 6-10%, there is a high non-linear correlation between the weft crimp and Poisson's ratio. In addition, there is a high non-linear correlation between Poisson's ratio and fabric cover factor.
