Elastic weft knitted single jersey fabrics are produced by plating of elastane (elastomeric polyurethane) yarn with lyocell yarn in a circular knitting machine with positive feeder. This type of fabrics and their cloths have great response in the market as they have the tendency to re-gain their original size and shape due to physical extension by any part of human body. This research analyzed the effect of elastane plating on the physical and thermal comfort properties such as GSM, thickness, stitch density, air permeability, water vapor transmission rate, thermal conductivity and thermal resistivity of lyocell single jersey knitted fabrics by varying the loop length. The work revealed that the physical properties like stitch density, thickness and GSM increased with increase in elastane content and decrease in increasing of loop length. The air permeability, water vapor transmission rate and thermal resistivity of the fabrics decreased with increasing of elastane plating and increased with increasing of loop length. The thermal conductivity values of the fabrics are not much significant at 95% significance level. [ABSTRACT FROM AUTHOR]

After reviewing the past work into the characterization of weave structures and their relationships with various properties of fabrics, an account is given of the present knowledge of them on comfort properties which represents one of the major areas that have been neglected in garments. The shortcomings of this knowledge are shown to be that, although many studies have been conducted on comfort, there have been no systematic studies of weave structures and their impact on comfort. Thermal comfort properties of fabrics are affected by a gamut of fiber, yarn, and fabric properties. In this study, the characterization in the comfort properties, namely thermal resistance and thermal conductivity, has been studied as a function of weave structures and other geometrical properties.

The influence of air, oxygen and argon plasma treatment on the thermal comfort behavior of cotton woven fabric which is spun from modified yarn path in ring spinning has been investigated in this study. The cotton fabric samples were undergone different plasma treatment namely air, argon and oxygen. The fabric air permeability has tend to be decreased with the plasma treatment and the oxygen plasma-treated fabric has least air permeability. The untreated fabric shows higher air permeability followed by left diagonal yarn path, straight path and right diagonal yarn path. It was also observed thermal resistance and water vapor permeability of the fabric has increased with the plasma treatment and the oxygen plasma-treated fabric has higher thermal resistance and water vapor permeability. The untreated fabric shows lower thermal resistance and water vapor permeability followed by left diagonal yarn path, straight path and right diagonal yarn path. [ABSTRACT FROM AUTHOR]

Effect of Musa acuminata SAP on the air permeability of the finished cotton fabric Water vapor permeability The influence of I Musa acuminata i SAP on the water vapor permeability of the finished specimen is described in Figure 3.

Two-way ANOVA was utilized to identify the significance of differences between finished and controlled fabric samples and fabric physical properties, thermal comfort properties of woven finished fabric samples.

The tri-layer knitted fabrics created for the aim of active sportswear have been enhanced with the help of microdenier filament polyester yarn, spun polyester yarn, polypropylene, and cotton in this study. These developed trilayer knitted fabrics are then examined for the thermal comfort properties. The results evidently showed that Microdenier Polyester/Microdenier Polyester/Cotton tri-layer knitted fabrics combination shows exceptionally appreciable thermal comfort properties due to their structural factors such as filamentous nature, lesser thickness, low areal density, and lesser bulkiness. The effect of fiber chosen also plays a crucial part with respect to the thermal comfort properties of tri-layer fabrics developed. Samples such as Microdenier Polyester/Polypropylene/Cotton, Polypropylene/Microdenier Polyester/Cotton also performed better next to that of the Microdenier Polyester/Microdenier Polyester/Cotton combination because polypropylene also possesses a good wicking characteristic. A poor thermal behavior was found in the Microdenier Polyester/Cotton/Polypropylene sample because of the reasons such as protruding fibers of cotton, increased thickness, high areal density, etc. Also on comparing between the filament and the spun yarn, the filament yarn is highly recommended due to its appreciable behavior. Results evidently show that Microdenier Polyester/Microdenier Polyester/Cotton combination possesses an exceptionally appreciable thermal comfort property. [ABSTRACT FROM AUTHOR]

In this study, 100% Eri Silk, 85:15% Wool/Eri silk, Cotton, and Micro-denier Acrylic yarns have been used to develop double-layered knitted fabrics. The thermal comfort properties such as air permeability, thermal resistance, thermal conductivity, and water vapor transmission have been evaluated. In this study, it is found that 100% eri silk double-layered knitted fabrics have better air permeability properties when compared with the other fabrics (85:15% Wool/Eri silk and 100% micro-denier acrylic fabrics) due to their thin and porous structure. As far as thermal conductivity is concerned, 100% Eri silk double-layered knitted fabrics have better thermal conductivity, whereas 85:15% wool/Eri silk double-layered knitted fabrics show poor thermal conductivity. In the case of thermal resistance, 85:15% wool/Eri silk double-layered knitted fabrics have maximum thermal resistance and 100% Eri silk shows poor thermal resistance when compared to other samples. A total of 100% Eri silk double-layered knitted fabrics have better water vapor transmission and 85:15% wool/Eri silk double-layered knitted fabrics have poor water vapor transmission when compared to other samples.
