The effects of chemical treatments and modifications on the tensile properties of ring‐and rotor‐spun cotton yarns is discussed. The rotor‐spun yarns treated with zinc chloride show a higher tenacity at low stretch levels compared to sodium hydroxide, whereas with sodium hydroxide, the rotor‐spun yarns show higher tenacity at higher stretch levels compared with zinc chloride. The aqueous‐treated rotor‐spun yarns show a higher change in tenacity compared to ring‐spun yarns. Sodium hydroxide‐treated yarns before resin treatment show a higher retained tenacity compared to zinc chloride‐treated yarns. The substitution treatment after swelling and stretching to 100% shows a higher tenacity than that of the slack substituted yarns. © 1995 John Wiley & Sons, Inc.
