POLYAMIDE ROLL

Polyamide Roll

Polyamide rolls are the modern form of Calendaring roll which are produced by mounting a casted polyamide cylinder on the solid steel shaft. Polyamide material is more resilient and tougher than cotton bowl and paper bowl and therefore it provides higher hardness, better nip and more speed.
Similar to cotton bowl polyamide rolls are used on Textile calendars for calendaring which can be 3-bowl configuration or 5-bowl configuration.

Advantages of Polyamide Roll:

  • High hardness: Hardness is achieved by using best grade of polyamide for high hardness without the sacrifice of the toughness. This means that the roll is still mark resistant and cannot be easily indented by the selvedge marks.
  • High Gloss: The polyamide sleeve can attain the higher surface finish value since it is produced from the long chain polymers.
  • High Speed: The polyamides can run on more speed compared to the cotton roll as the nip load is much higher in this roll. This increases the total production quantity and more lusture
  • Easy Installation: Polyamide rolls are ready to use and requires no conditioning like cotton rolls which takes 36-48 hours of time before taking it in the production.
  • Lesser grinding frequency: The polyamide rolls do not require frequent grinding and whenever required only few millimetres are lost in the grinding and hence lasts longer.
