This paper describes the tensile and frictional behavior of wool-cotton union fabrics developed using different wool-cotton blended warp yarns, and mixed wool weft yarns spun on khadi spinning system. The tenacity and elongation at break of fabric increase with the blending of cotton with JK crossbred wool in the warp direction and high content of Australian merino wool in the weft direction, however, initial modulus decreases. The static and dynamic coefficient of friction positively correlates to the wool content in warp yarn and negatively correlates with linear density and the proportion of Australian merino wool in weft yarn.
