Abstract
This study focused on the effects of varying the warp and weft densities and blend ratio on the overall liquid transport behavior of plain woven 100% cotton and polyester/cotton blended fabric. Overall Moisture Management Capability (OMMC) and Accumulative One-way Transport Index (AOTI) along with wetting and spreading time of the top and bottom surfaces was measured on moisture management tester. The results were used as a basis to grade the fabric for its moisture transport behavior. It was observed that polyester/cotton blends have an overall higher accumulative one-way transport index and overall moisture management capability than 100% cotton fabric. Furthermore, an increase in the polyester content in the fabric resulted in a significant increase in the transport of moisture. However less number of warp and weft yarns in the blended fabric improved the overall moisture management capability of the fabric.
Highlights
The thermo-physiological comfort level of apparel can be determined by its ability to transport perspiration from the layer next to the skin to the outer layer and subsequently to the environment
Fabrics that are coated with a layer and have impurities are not recommended for fabric thickness and moisture management testing as presence of these impurities have adverse effect upon the fabric absorbency and appearance
In order to evaluate the effects of blend ratio and density on the Accumulative One-way Transport Index (AOTI) and Overall Moisture Management Capability (OMMC) value of the fabrics Analysis of Variance (ANOVA) test was performed
Summary
The thermo-physiological comfort level of apparel can be determined by its ability to transport perspiration from the layer next to the skin to the outer layer and subsequently to the environment. In hot and humid climate, perspiration affects wearer comfort. Wearer will feel more comfortable when this is quickly transported away from the skin in the form of a liquid or vapour. This is because the fabric touching the skin will feel dry. An effective moisture management system includes complete transfer of moisture vapour and liquid from the skin to the environment [1]. The moisture management properties of a fabric are influenced by numerous factors such as the nature of fibre (hydrophilic or hydrophobic), blend ratio and yarn and fabric constructional parameters etc
