TECHNICAL ANALYSIS OF KNITTING PARAMETERS FOR BASIC STRUCTURES OF WEFT KNITTED FABRIC
Hundred percent Cotton knitted fabrics have a habit of certain dimensional changes due to different yarn count selection, knitting parameters and considering points prior to knitting. The research conducting area was knitted fabric manufacturing and quality assurance zone in a textile sector. This study was carried out to compare the influence of different yarn counts, stitch lengths, machine gauge and fabric structure on the GSM of knitted fabric. In this investigation the experimental outcomes indicated that when yarn counts were fixed, the raise of stitch length results reduction of GSM. On the contrary, when stitch length is fixed, the raise of yarn count results reduction of GSM. Out of four basic structures three basic structures were investigated in this study. All the analysis was compared to theoretical implications and approached with some advisable points to be considered prior to knitting production. This comparative study built a bridge to select adequate yarn count with suitable machine gauge to facilitate stitch length calculation. To produce fabric of certain GSM (gram per square meter) is really a challenging job for the manufacturing personnel as because the total activity highly dependent on yarn count, stitch length, machine gauge, operating conditions and other related factors. Most of the knit fabric manufacturer used historic data for predicting those quality parameters, while others used trial and error method in order to keep the GSM of the produced fabric close to the required value. It was seen that machine gauge and yarn count holds a key role in knit fabric structures and design. It had been recognized that to meet buyers required finished GSM of the fabric machine gauge should be considered carefully to select right yarn count which influenced on stitch length calculation and proper machine setting.
