Air covered yarn is manufactured by creating a physical intermingle of INVIYA® yarn with other synthetic filament like Polyester or Nylon with the help of compressed air applied through a nozzle.
INVIYA® is applied during a draw texturizing process of Polyester or Nylon to avoid the extra process of spandex application.
Core spun yarn is characterized by having a central core wrapped with staple fibers. These are produced in a single operation by simultaneously feeding a core filament and staple fibers through the delivery rollers of a spinning frame.
Applications of Core-Spun yarn
– Core spun yarn are inherently fire-resistant fibres.
– To make fire barriers for mattresses and furniture.
Suitability of Air Covered Yarn
INVIYA® I-400 is suitable to apply during the 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 to a wide range of drafts during the draw texturizing process depending on the required content. The 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 the start, middle, and bottom of the spool.
INVIYA® can run on a high-speed texturizing machine keeping the efficiency high.
Load and unload power of INVIYA® is balanced which is appropriate for the required stretch and recovery property of the finished fabric.
INVIYA® retains its properties during heat setting in a secondary heater at 180o C however; its stretch power may get affected with temperature going beyond 180o 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 170o C to 180o C for a dwell time of maximum of 30 seconds
