<span style="font-size:11.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-bidi-font-family:="" mangal;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:="" zh-cn;mso-bidi-language:hi"="" lang="EN-US">In this study, solo-sirofil yarns under 5-30 cN filament pre-tension have been produced using modified EJM-128K ring spinning frame. The hairiness, breaking strength, breaking energy and yarn evenness have been tested under standard test conditions. It is observed that at 15 cN pre-tension of filament, solo-sirofil yarns show the best performance with lower hairiness, higher breaking strength &amp; breaking energy, and better yarn evenness. The experimental results are helpful to understand the characteristics of the composite yarn produced by solo-sirofil system. </span>
