Abstract
The effect of different stitch combinations, namely, knit, tuck and miss stitches, on some of the physical properties of single jersey derivative fabrics have been studied. Fabrics which are in common commercial use in the textile industry were selected, and they are used as clothing fabrics. Knitted fabrics from 100% cotton yarn of 19.67 Tex on circular knitting machines were used in the study. The effect of knit structure on areal density, fabric thickness, air permeability, drape ability, stretch and recovery, shrinkage, and low-stress mechanical properties are investigated, and it was found that these properties are significantly affected by loop shape or knit structure, even though other knitting parameters remained the same. It was also found that the presence of tuck and float stitches for a given structure have a significant effect on fabric drape ability, width-wise extensibility, length-wise shrinkage, thickness, areal density and low-stress mechanical properties.
Highlights
Plain, rib, interlock and purl are the four basic wefts knitted structures from which all other weft-knitted structures can be derived
Three different single jersey derivative structures made from tuck stitch, knit stitch and miss stitch incorporated with knit stitch were produced (Figure 1)
It was shown that almost every stitch has a significant effect on dimensional and comfort properties even when other knitting and yarn parameters remain the same
Summary
Rib, interlock and purl are the four basic wefts knitted structures from which all other weft-knitted structures can be derived. The physical and mechanical properties of these basic structures differ widely. Due to the structural difference, knitted fabrics are used in different applications.[1] Different stitches and stitch combinations affect the properties of knitted fabric. The physical property of knitted fabric mostly depends on loop structure, stitch density, types of yarn ring, rotor, compact, type of raw material fiber, composition of yarn, twist level, and so on.[2] In addition to the knit structure, there are different factors, which affect the physical properties of weft-knitted fabrics. Some of them are:; yarn variables, such as yarn strength, count, evenness, twist, extensibility, rigidness and finishing treatment; machine variables such as machine gauge, speed, needle timing, needle arrangement, knitting elements and so on; knitting variables such as feeding type or input tension and fabric takedown tension; and state of a fabric, such as obtained just after production from knitting machine, dry relaxed state, fully relaxed state and finished state.[2]
