High Shrinkage Yarn Production
The TSP electrical contact heater attachment enables high shrinkage yarn production on existing false twist texturing machinery, without permanent changes to the machine.
Depending on yarn type and process settings, shrinkage of 25% to over 30% can be achieved at processing speeds above 500 m/min. The heater configuration and yarn path are selected to suit the required shrinkage and yarn quality.
Heating and Yarn Handling
Lower Temperature Processing
Conventional vapour phase heaters have a typical minimum working temperature of 160°C.
The short electrical contact heater provides the lower temperature processing options required for high shrinkage applications.
Operating Temperature
The heater operates from ambient temperature to 245°C.
The working temperature is selected to suit the yarn and required shrinkage.
Two Yarn Tracks
Each heater has two yarn tracks, with capacity to process two yarns simultaneously.
Guides and Twist Stoppers
Twist stoppers and ceramic guides are positioned at the heater exit.
Rotating guides above the input feed direct the yarn towards the twist stopper.
Installation and Changeover
Clamp Mounting
The attachment clamps to the existing primary heater without permanent modification to the machine.
Standard Yarn Threading
The normal threading path remains accessible, allowing the operator to thread the machine for standard production.
Cooling System Alignment
The machine’s existing cooling tubes or tracks are reused.
The input end is lowered to align with the heater exit.
Return to Standard Production
The attachment can remain in place during standard production.
The cooling tube or track can be returned to its original position.
