This paper focuses on the anti-static performance of absorption and quick-drying knitted fabrics using in sportswear. Firstly, the parameters such as fiber component, fabric structure, thickness and density are obtained, and the anti-static performance of 11 kinds of knitted fabrics is tested using the static voltage. Secondly, the anti-static performance is explained by parameters based on improved regression and principal component analysis. According to the analysis, an explained and forecast model is build. This can be a guide to set the parameters during the multi-property knitted fabrics design and manufacture.
