The raw materials features, product development ideas and spinning technology of Australian wool/hemp/cashmere 60/30/10 knitted yarns (19.2 texx2) were characterized in this paper. The fabric blended with hemp fiber, Australian wool and cashmere blended woven fabric have natural antibacterial function. In order to meet consumers' requirements on antibacterial fabrics, it is necessary to improve the antibacterial ability of yarns.
