Abstract: Knit fabric manufacturers particularly those who are involved in producing weft knitted fabrics are continuously facing the problem of adjusting different quality parameters in producing a fabric of predefined structure. Predicting the yarn count, stitch length and appropriate machine gauge in order to produce fabric of certain GSM is of great importance in this regard. This study aims at emphasizing the importance of the linear relationship among those quality parameters and implementing statistical methods and techniques in order to develop a linear relationship among different quality parameters in making different weft knitted fabrics.
