Introduction
The Stenter machine consist of seven drying chambers, padded rollers and a weft straightening section which enables the machine to control spiraling, shrinkage, GSM during the fabric is passed through the padding section or squeezer for properly squeezing the fabric and processing softening treatment of the fabric through feed roller and guide roller. Then it goes through the weft, straightening section where, by bowing roller, fabric spiraling is controlled and then passed through a chain rail for shrinkage control.

Function
- To adjust the length and width of the fabric
- To dry the fabric
- To give the dimensional stability of the fabric
- Used for heat setting
- Used for straightening the weft or coarse yarn.
Hot Air Circulation System
In Stenter and dryer machines, air is recirculated, which passes from the exhaust stubs and air controller flaps. Then the air is passed over the nozzles through which fabric is passed and routes it over to the heat exchanger, which lets the air be heated by the burner. The circulating air fan allows the hot air to pass uniformly through the nozzles to the fabric where the air controller flaps control the upper and lower nozzle air and thus the fabric is heated. Finally, the used hot air is passed on to the exhaust air duct.
Finishing Effect of Stenter Machine
Process Description
The selvages are held by two endless chains typically 40 to 60 meters in length and the fabric is conveyed through a series of heated compartments or bays. Hot air is directed onto the fabric equally from above and below. The selvages are held either on pins about 5 mm long mounted in baseplates or by clips that grip the selvages between smooth surfaces. Lubrication of the chain is important and this takes place automatically during running. The lubricant must be completely stable during continuous high temperature operation.
