The main purpose of the research is the development and analyzes the characteristics to increase the comfort for shoe insole application. Made of two separate fabric parts or layers, top and bottom and interlaced by yarns oriented in three dimensions, a warp-knitted spacer fabric is a real 3D fibrous structure. Therefore, in this research, warp knitted spacer fabrics used for shoe insole application were produced using polyester /nylon with Rachel double needle gauge of 28E, 6 guide bars. The spacer fabric characteristics were evaluated as per standard. The warp knitted spacer fabrics can replace the existing PU foam’s shoe insoles, made to have comfort, recyclable, and environmentally friend. Statistical Analysis System (SAS) software was used for analysis. The spacer fabrics have significant compressibility and porosity which result in good cushioning and permeability.

Raw materials & their quality are known to be the most important factors which determine the quality of yarn. There are various properties which determine the quality of yarn; some of them are known to be the prominent properties of ring spun yarn. In this study some prominent properties of Ring spun yarn produced from different types of cotton fiber including splice strength, Imperfection Index, Yarn hairiness, yarn unevenness, yarn RKM, Elongation, CSP were investigated in detailed. For this purpose, yarns from three different cotton types like Ivory Coast, Mali & Cameron of having same count were undergo various tests to find out the better-quality yarn. Result showed that there was significant difference between the ring spun yarns with respect to various properties.

The application of textile products in functional area like sportswear has been increasing in last decade. The thermal properties of knitted fabric sample made up of polyester and cotton were studied for football sportswear. Six samples were manufactured, two were plain, two ribs and two are bi-layer interlock structures. Airflow and WVP (Water vapor permeability), thermal properties, and drying capacity of bi-layer knitted samples made up of polyester as the inner surface and cotton as the outer surface. The outcome indicates bi-layer samples with polyester as the inner surface and cotton as the outer surface having single(one) tuck point of replication is preferable for football wear. The thickness, structure and weight of the sample have great influence on the thermal comfort properties of bi-layer knitted fabrics. As thickness of the sample increases the thermal property, air permeability and drying ability decreases and higher absorbency. The results are discussed together with Statistical analysis system (SAS) test results at a 95% significance level.
