The strength and elastic recovery characteristics of ring-spun and rotor open-end-spun cotton, polyester, polyester/viscose rayon and cotton/polyester are examined at different strain levels. The cotton ring-spun and rotor-spun yarns can be strained up to 2％ extension without causing any permanent deformation to their structure, whereas the other yarns can be extended up to 3％ Sizing increases the yarn modulus by about 2.6 times up to 2％ strain level when compared to grey yarn. To forecast the performance of sized yarns in weaving, their modulus behaviour at 3％ extension may be given preference over their ultimate breaking tenacity.
