<span style="font-size:11.0pt;font-family:" calibri","sans-serif";="" mso-ascii-theme-font:minor-latin;mso-fareast-font-family:"times="" new="" roman";="" mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">The effect of stretch during sizing on the frequency distribution of breaking elongation of sized yarn at break and its impact on warp breakage rate was studied. The frequency of low-elongation yarns increased out of proportion with increase in stretch, which in turn increased the warp breakage rate. The beam sized at high stretch level also behaved erratically in terms of warp breakage rate in the loomshed. A linear relationship between the warp stretch and the loss in yarn elongation during sizing was established.</span>
