Air covered yarn

INVIYA^® I-400 is suitable to apply during draw texturizing process at various drafts as per the required stretch in the covered spandex yarn. It can be applied on both the type of attachments like with auto-spool changer and manual-spool changer of spandex spools without affecting the performance.

• INVIYA^® can be applied on a wide range of draft during draw texturizing process depending on the required content. A minimum content of 5% is advisable for imparting optimum recovery to the fabric.
• Uniform run-ability of Spools maintains the performance and properties of INVIYA^® between start, middle and bottom of spool.
• INVIYA^® can run on high speed texturizing machine keeping the efficiency high.
• Load and unload power of INVIYA^® is balanced which is appropriate for required stretch and recovery property of finished fabric.
• INVIYA^® retains its properties during heat setting in secondary heater at 180^o C however; its stretch power may get affected with temperature going beyond 180^o C.
• Since INVIYA^® goes through one heat treatment process during texturizing, a complete heat setting process of fabric is generally not required. However, if the fabric width is not stable, it can be heat-set at 170^o C to 180^o C for a dwell time of maximum 30 seconds

The below application parameters are broad guidelines for Air Covering with INVIYA^® during texturizing process which may vary with machine parameters, running speed, fibre content, etc.
