The investigation of physical characteristics of compact yarn weft knitted fabrics after treatment with enzymatic scouring, bleaching and natural dyed with Acacia catechu have been studied and compared with ring yarn weft knitted fabrics. In this research work the physical characteristics such as weight loss (%) in abrasion, pilling resistance, air permeability, fabric tightness factor, loop shape factor, wickability, bursting strength, spirality and dimensional stability have been studied with various knit structures and stitch length. From the test results, the spirality (%) of the Com4 and Sussen Elite spun yarn knitted fabrics had lower values when compared to ring spun yarn knitted fabrics. The higher weight loss (%) in abrasion was noticed in ring yarn knitted fabrics compared to compact yarn knitted fabric made out of Sussen Elite and Com4 spun yarns. The pilling resistance of these knitted fabrics has been observed higher in case of 2.7 mm stitch length compared to 3.3 mm stitch length, because of the higher fibre content and probability to form fuzzing on the surface of the fabric. The compact spun yarn knitted fabrics in all the knit structures were noticed lower dimensional shrinkage and also noticed that the aerial shrinkage of the knitted fabrics mainly depends on the stitch length, loop shape factor and tightness factor of the fabrics. The significant differences of the physical characteristics of these knitted fabrics were analyzed using ANOVA multivariable data analysis. This research study will be helpful for particularly knitwear industries and designer who are analyzing and dealing with compact spun yarn knitted fabric and garments through eco-friendly processes.
