Abstract
The main aim of this study is to determine the thermo-physiological comfort properties of single knit fabrics and their derivatives. As the Single Jersey knitted fabrics are the most widely used fabrics in the apparel sector, they have been selected for the analysis purpose. Derivatives of single jersey are developed and compared in order to understand the influence of structural variations. Physical properties e.g. thickness and areal density were evaluated for all knitted fabrics with 100% cotton yarn having three different yarn linear densities and after different stages of relaxation. Various thermo-physiological properties have been studied by changing the combed cotton yarn linear density as well as the structure of single knit fabric. Air permeability, thermal insulation and relative water vapor permeability of the fabrics were observed and investigated under wet relaxed states. It is determined that fabric physical properties are affected by changing yarn linear density and by the dry or wet relaxation stages. The percentage/number of tuck stitches (NTS), location of tuck stitches (LTS) and ratio of tuck to knit stitches (RTKS) have strong influence on physical and thermo-physiological properties of single knit fabrics, even though other knitting parameters remained the same.
Highlights
A dominant segment of consumer market is occupied by knitted fabrics due to their exceptional properties like light weight, economic production and excellent elasticity
The study mainly focused on effect of combed yarn linear density and loop pattern of single jersey knitted structures on their thermo-physiological comfort related properties
During evaluation of experimental study findings with respect to comfort, it was observed that air permeability, thermal resistance and moisture management properties of single jersey knitted fabrics and derivatives are affected by the change of stitch type
Summary
A dominant segment of consumer market is occupied by knitted fabrics due to their exceptional properties like light weight, economic production and excellent elasticity. As knitted garments provide excellent comfort and high flexibility, their application is wide spread to versatile areas like medical, protection, sports and geo applications. Different types of weft knitted structures are produced e.g. single jersey and double jersey. Single jersey is widely used for regular and sports t-shirts, leggings and for other garments. Its derivatives can be produced by changing types of stitches and their arrangements for design purposes (Islam, 2014; Kane et al, 2007). The understanding of fabric properties and their relationship with end use becomes a basis for research, classification, quality control and selection of fabrics used for apparel. Most important component of the clothing functionality is thermo-physiological
