Abstract: Spirality is a major issue for single jersey knitted fabrics due to their asymmetrical loop formation. The reported study studied the effects of yarn count, loop length, course per inch (CPI), wales per inch (WPI), and fabric counts on spirality of five single jersey knitted fabric of different yarn counts. The reported study tested all controlled specimens of 100 % cotton and untreated fabrics. Six hypotheses were developed to test the relations. The American Society for Testing and Materials (ASTM) standard were used to determine standard atmospheric conditions for conditioning (ASTM D1776) and fabric count (ASTM-D3887). Industrial method was used to measure spirality, and loop length. All the statistical analysis was carried out using Statistical Package for the Social Sciences (SPSS) software. Collected data were analyzed by statistical means, t-test analysis, and Analysis of Variance (ANOVA). Significant correlations were found for yarn count, course per inch (CPI), wales per inch (WPI), and fabric counts to the spirality, but no significance found between the loop length and the spirality.
