Abstract: The physical, geometrical and metallurgical properties such as hardness, elemental composition, grain structure, nature of hardness, surface smoothness and geometrical profile of the various makes of imported and indigenous spinning rings have been critically analysed to study the performance of these rings in terms of end breakage rate, traveller damage and yarn quality. The occurrence of micro-welding is also studied in these rings. Imported rings show relatively less variation in their properties and are smoother in surface finish when compared to their indigenous counterparts. Hardness decreases for all the rings after usage. A marginally higher ring ovality helps the traveller to change its point of contact with rings and thus avoids the localized heating of traveller. A smaller off-set web results in reduced point of contact with the traveller and consequently higher burning rate and traveller weight loss. In the case of larger ring diameter, higher spindle speed and coarser count, the wearout of ring is faster. Performance study shows identical yarn quality for all makes of rings.
