Tensionless Dryer
  • Tensionless Dryer
  • Tensionless Dryer

Usage of the machine:

This machine adopts three pass web belts tensionless drying, the hot air from the large centrifugal blower goes through the fabrics, the fabrics are shrunk through the three layers web belts, during the drying period, the fabrics move in large wave mode, completely non tension.

The fabrics stay long time in the drying chambers; so that the water inside the fiber and outside the fiber is uniform, eliminate the difference of the fabrics two sides radically. If fabrics dried by single pass dryer, inside and outside water of the fiber is difference, outside is too dry and inside is too wet, after treated, the fabrics colors changed, reduce the fabrics quality. But the three pass relax dryer had overcome this point.

The fabrics treated by this machine have soft hand-feeling, low water shrinkage and fabrics quality is enhanced. It has the advantage of saving energy、high efficient, high automatic and easy to operate. So it has become one of the most ideal drying devices.

The appearance of the machine is beautiful, the entire frame, chambers, panels are made of super carbon steel, and surface are specially treated.
