Abstract: Tearing strength of cotton fabrics made of ring- as well as compact-spun weft yarns has been studied in relation to certain process and loom parameters. It is observed that the fabrics made of compact-spun weft yarns are more tear resistant. The tearing strength further improves particularly in the weft-way direction with the increase in weft yarn linear density and weft tex twist factor. There is an initial increase in strength followed by a decrease as the number of picks/inch is increased in the cotton fabrics made of compact-spun yarns. However, for the fabrics made of ring yarns, it shows a general decreasing trend. The 2/2 designs are found to be superior in warp-way but inferior in weft-way directions. The fabrics woven on air-jet looms show lower tearing strength than those woven on projectile looms. The mechanical finish as well as the variation in shed opening do not affect the tearing strength of cotton fabrics produced from compact-spun weft yarns.
