Evaluating the thermal properties of knit fabric made of 100% conventional cotton and BCI cotton

The study discusses research findings on the thermal characteristics of BCI cotton, 100% conventional cotton, and blends with polyester and elastane. The investigation emphasises single-jersey, rib jersey, and single-jersey blend arrangements. The thermal properties of the recommended knitted material configuration were assessed. The results indicate that each fabric composition with a varied structure exhibits distinct thermal characteristics. BCI cotton fabrics have good uniformity and structure due to cultivation compliance, better thermal conductivity, air permeability, and thermal transmittance. They are eventually better for sportswear and summer apparel products. However, it is essential to consider that the other side of both rib and single jersey fabrics made of conventional cotton with less uniformity includes a more significant CLO and thermal resistance value than BCI cotton fabrics, giving a warmer feeling and being more fruitful for winter clothing with better-trapped air and heat. Thermo-physiological comfort is influenced by various factors such as fiber content, yarn quality, fabric finish, structure, and heat and water vapor resistance, which increase with material thickness and air entrapment in the fabric.
