      다국어 초록 (Multilingual Abstract) kakao i 다국어 번역

      Strength and elongation have long accepted by many as the most vital characteristics of yarn,
      Tensile and elongation in physical properties of cotton yarn can be evaluated from single end strength and elongation at break,
      In this thesis, as the results of single end test, single end strength and elongation with varying yarn count and T.M.(Twist Multiplier) were measured by experiment and also the effects of T.M. on the single end strength and elongation were investigated in various yarns, thus conclusions could be found as follows:
      1. Optimum twist multipliers at maximum single end strength of open-end and ring spun cotton yarns were found to close at the point of T.M.6.3 in O.E.(open-end yarn) 10Ne,T.M.5.6 in C.D.(carded yarn} 20Ne,T.M.5.5 in C.D.30Ne and 40Ne,T.M.5.9 in C.M.(combed yarn)58Ne.
      2. Single end strength of open-end and ring spun cotton yarns decreased as the yarn became finer.
      3. T.M. at the minium single end strength CV% of cotton yarns was found to occur at the points of T.M.6.3 in O.E.10Ne, T.M.4.0 in C.D.20Ne, T.M.4.4 in C.D.30Ne, T.M.4.7 in C.D.40Ne, T.M.3.9 in 58Ne.
      4. Elongation at break of open-end ring spun cotton yarns increased as the yarn became coarser.
      5. Elongation at break of cotton yarn was found to increase whenever T.M was increased in C.D. 30Ne and C.M. 58Ne, but at first in O.E.10Ne and C.D.20Ne it increased, afterwards it was found to decrease suddenly at the points of T.M. 9.5 in O.E.10Ne, T.M.8.9 in C.D.20Ne.
