Abstract: The effect of doubling on physical properties of regular ring-spun and compact yarns has been studied in terms of structural parameters, like fibre extent, spinning-in coefficient, fibre pair overlap length, packing coefficient and migration of fibres. The structural parameters, like fibre extent, spinning-in coefficient, fibre pair overlap length and packing density increase and migration parameters decrease after doubling for both the ring-spun and compact yarns. The percentage increase in tensile strength and percentage decrease in breaking elongation are found to be higher and lower respectively in ring-spun yarn than in compact spun yarn on doubling. Doubling process also reduces the hairiness of both ring-spun and compact yarns; the extent of hairiness reduction on doubling is higher for ring-spun yarn
