Prediction of Stitch Length of Knitted Fabric From Yarn Input Tension and Yarn Delivery: An Independent Technique Than What Industry Practitioners Use

---

Abstract

The industry practitioners calculated the required yarn delivery rate and adjusted the Quality Adjustment Pulley (QAP) to match between the drive belt speed and required yarn delivery rate for knitting. However, the required yarn delivery rate and subsequent stitch length are always higher than the actual stitch length in the fabric measured after knitting. The purpose of this study is a) to predict the stitch length from the measurement of yarn input tension and yarn delivery b) to determine the actual value of stitch length, and c) to determine the difference between these two independent measurements. Four cotton single jersey fabric specimens were knitted, and the yarn delivery rate was kept. A linear regression analysis was then implemented to predict course length. Six, two-sample t-test were carried out for the actual course. The analyzed data represented that the average actual course length was higher than the predicted one.
