<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" calibri;mso-fareast-theme-font:minor-latin;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:arial;mso-ansi-language:en-us;mso-fareast-language:en-us;="" mso-bidi-language:ar-sa"="">Studies conducted on the effectiveness of new air texturing jets {Hema Jet T100 and Taslan XX) in opening up and bulking twisted filament yarns show that these jets are able to texture continuous filament yarns twisted in both Z and S directions. While the physical bulk of the textured yarn made from pre-twisted feeder yarn is lower than that of the textured yarn made from zero twist feeder yarn, the former has a more stable structure. An increase in twist density in the feeder yarn reduces bulk but enhances stability and tenacity of the textured yarns. The direction of twist in the feeder yarn has no effect on texturability.</span>
