Abstract: This paper is focused on change in shrinkage, GSM, Wales per Inch and Course per Inch due to structure and count variation and state variation. This work was carried out with 12 samples of single jersey, single lacoste and weft lock knit fabrics of different counts which were scoured with NaOH. After pretreatment process the samples were tested for widthwise shrinkage, width, GSM, Wales per Inch and Course per Inch and compared between different states like grey state and finished state. The result obtained in this research indicated that physical properties like structures with tuck stitch possess higher value of widthwise shrinkage, width, GSM and Wales per Inch and Course per Inch value lowers prominently in those structures having float or miss stitches. In both cases i.e. grey state and RFD state values of those properties are high in coarser yarn and low in finer yarn. During project knitted fabrics specification along with machine specification and major factors which are necessary to calculate different types of variation and variables on which the whole fabric construction depends were managed to watch carefully. Main efforts were to develop a dependable way so that the resulting fabric specifications with required configuration can be easily visualized and be forecasted. A great emphasization was provided to the adjustable points on which fabric GSM, stitch length, fabric width and shrinkage percentage directly or indirectly depends.
