Analyzing the Factors by One-Way ANOVA Associated with Plain Weft Knitted Fabrics’ Production

Bangladesh has achieved a significant reputation for RMG exporting over the last three decades, particularly in knitwear. The knitwear sector is one of the self-supporting sectors of Bangladesh, which could meet 90% of the fabric requirements. However, there is an empirical relationship between machine diameter and fabric diameter. It’s assumed that the machine diameter determines the fabric diameter. Therefore, the objectives of the study were to test the significance of average shifting in fabric diameter from machine diameter and the overall effect of machine diameter on fabric diameter. Empirical research has been conducted for such an investigation. This study was carried out with a few factories and a full lot of each factory was inspected. Based on the collected data, diameters of machines were grouped into three levels to understand the variation of fabric diameters. Then, SPSS software was used to analyze the collected data, applying one sample t test and one-way ANOVA. However, the result of the analysis revealed that machine diameter has no effect but indicative means reduction were found in fabric diameters. In the future, more comprehensive studies could be done by including larger data. But now, these findings will help all the personnel related to the quality and production of knitted fabric.
