Technical properties of polyester fabric produced with different weft densities / Nurul Syazwani Abdul Latif

Physical and technical properties of woven fabric together play an important role to produce good quality fabric. The objective of this study is to analyse the effect of polyester woven fabric technical properties which includes air permeability, abrasion resistance, wrinkle recovery, stiffness and friction when produced with different weft densities. Weft density refers to the number of weft yarn in centimeter. In addition, this study aims to investigate the relationships between physical and technical properties of fabric using pearson correlation coefficient. Plain polyester woven fabric was produced using Sulzer Rapier Loom machine with three different weft densities, which are 15 weft per centimeter (wfcm), 20wfcm and 25wfcm. The fabric samples underwent both physical and technical testing. Physical measurements includes cloth cover factor, crimp, weight, and thickness. The results were analyzed using Pearson Correlation Coefficient. It is revealed that the changes in weft densities has an effect on the performance of the fabric's technical properties. The fabric stiffness and friction were directly proportional to the increment number of weft density. Meanwhile, fabric abrasion resistance, air permeability and wrinkle recovery were inversely proportional to fabric weft density Furthermore, results have also shown the analysis using Pearson correlations Coefficient for all technical properties which include fabric weight, thickness, cloth cover factor, density and crimp have high relationships toward the technical properties except for abrasion resistance.
