Study of Thermal Comfort Properties of Cotton/Regenerated Bamboo Knitted Fabrics

2 Abstract: This paper presents the thermal comfort properties of single jersey knitted fabric structures made from cotton, regenerated bamboo and cotton-bamboo blended yarns. Cotton, bamboo fibre and blends of the two fibres (100% cotton, 100% bamboo, 50:50 cotton: bamboo, 67:33 cotton: bamboo, 33:67 cotton: bamboo) were spun into yarns of identical linear density (20 tex). Each of the yarns so produced was converted to singl e jersey knitted fabrics with loose, medium and tight structures. The thermal conductivity of the fabrics was generally found to decrease with increase in the proportion of bamboo fibre. The water vapour permeability and air permeability of the fabrics were observed to increase with increase in bamboo fibre content. Statistical analysis also indicates that the results are significant for air permeability, thermal resistance, thermal conductivity and water vapour permeability of the fabrics.
