Bamboo lyocell fiber had gained global recognition for its sustainability and functional performance. In this experimentalwork there is analysis and characterization of four types of knitted fabrics having blend compositions such as 100 % bamboolyocell, 100 % cotton, 70:30 bamboo lyocell/cotton, and 50:50 bamboo lyocell/cotton. The yarn and fabric samples wereanalyzed for their functional properties such as pilling resistance, dimensional stability (shrinkage), air permeability, watervapor transmission, and wicking behavior. The one way ANOVA results indicate that fiber blend proportion significantlyinfluences most of the evaluated fabric properties. No significant effect was observed for shrinkage in the wale direction(p=0.9820). However, course-wise shrinkage, air permeability, water vapour permeability and wicking behavior exhibitedhighly significant difference (p˂0.001). Fabrics with higher bamboo content demonstrated a more pronounced effect onthese performance characteristics The findings of experiment revealed that the 100% bamboo fabric exhibited superior airpermeability (125cm³/cm²/s) and water vapor transmission (5.88 g/m²/day), outperforming other blends. Resultshighlighted the potential of bamboo lyocell and bamboo lyocell/cotton blends to deliver enhanced moisture managementand breathability, offering sustainable solutions for both performance and casual wear applications. The functionalperformance had shown that the bamboo lyocell's may be potential source of sustainable, high comfort alternative in knittedapparel fabrics, offering significant environmental benefits.
